              Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine and sweat and water that condenses from exhaled air．They said"cheers"，clicked drinking bags and toasted NASA workers on the ground who were sipping their own version of recycled drinking water．
              The recycling system is needed for astronaut outposts on the moon and Mars．It will also save NASA money because it won't have to ship up as much water to the station by space shuttle or cargo rockets．Besides，it's important as the space station is about to expand from three people living on board to six．
              The recycling system had been brought up to the space station last November by space shuttle Endeavour，but it couldn't be used until samples were tested back on Earth．So when it came time to actually drink up，NASA made a big deal of it．The threeman crew stood，holding their drinks and congratulated engineers in two NASA centers that worked on the system．
              "This is something that had been the stuff of science fiction，"Barratt said before taking a small mouthful．"The taste is worth trying．"
              NASA deputy space shuttle manager LeRoy Cain called it"a huge milestone"．
              The new system takes the combined urine of the crew from the toilet，moves it to a big tank，where the water is boiled off，and the vapor is collected．The rest of the urine is thrown away．The water vapor is mixed with water from air condensation，and then it goes through filters．When six crew members are aboard it can make about six gallons from urine in about six hours．
              "Some people may find the idea of drinking recycled urine distasteful，but it is also done on Earth with a lot longer time between urine and the tap，"said Marybeth Edeen，the space station's national lab manager．
              The technology NASA developed for this system has already been used for quick water purification after the 2004Asian tsunami，Edeen said．
              "We are happy to have this water work through the system-we're happy to have it work through our systems，"Barratt siad．

              American scientists reported Wednesday that they had cloned embryos（胚胎）from a 9yearold male monkey and gained stem（主干）cells from them，reaching a longsought goal that may pay off someday in new treatments for people．
              The researchers warned that even if their procedure could be used to produce human stem cells，it is far too inefficient to be used in medicine．Human eggs are in short supply and are slow to obtain．The monkey work required 304eggs from 14female monkeys to produce just two batches（批）of stem cells，they wrote．
              Still，Dr．George Daley of the Harvard Stem Cell Institute，who was familiar with the work，told the AP it was"a very important evidence"that the process is practical in primates（灵长类动物），the group that includes monkeys and humans．
              Nature also published an evidence of the results by an Australian team．In an email to the AP，the journal said one reason was the highly publicized 2004fraud（欺骗）that came out of South Korea，where researchers claimed to have produced stem cells from a cloned human embryo．The journal emphasized that its request did not indicate mistrust of scientists in the cloning field．Instead，the statement said，because of"questions will likely be raised about the truth of the （American） experiments，given recent history in the cloning field，we view this as a relatively easy way of putting these questions to test．"
              The Australian study，by David Cram and others at the Monash University，used DNA analysis of the male monkey，the two monkeys that donated eggs for creating the embryos，and the stem cells．The result"proves beyond any doubt"that the stem cells came from cloned embryos，the Australians wrote in their Nature paper．

              (1) What's the main idea of the passage？ ______
              A. American scientists cloned embryos from a male monkey and gained stem cells from them．
              B. American scientists reached a longsought goal that may pay off someday．
              C. Human eggs are in short supply and are slow to obtain．
              D. South Korea claimed to have produced stem cells from a cloned human embryo．
              (2) What do the researchers mean according to the second paragraph？ ______
              A. The procedure could be used to produce human stem cells．
              B. There is still a long way to go to produce human stem cells．
              C. The monkey work required 304 eggs from 14 female monkeys．
              D. The procedure could not be used to produce human stem cells．
              (3) The attitude of Dr．George Daley to the research work of cloned embryos is ______ ．
              A. shocked
              		B. negative
              		C. approval
              		D. annoyed
              (4) The author gives the example of the 2004fraud of South Korea ______ ．
              A. to criticize South Korea
              B. to show this research is doubtful
              C. to emphasize this research is true
              D. to give recent history in the cloning field
              (5) From the last paragraph we can infer that ______ ．
              A. the Australian scientists are also doing the same experiment now
              B. the Australian scientists donated eggs for creating the embryos
              C. David Cram and others from the Monash University work in the USA
              D. the Australian scientists confirmed the truth and success of the procedure．

              Parents say that honesty is the best policy，but they regularly lie to their children as a way of influencing their behavior and emotions，finds new research from the University of Toronto and the University of California．
              Surprisingly little has been published on the subject of parental lying，so Gail Heyman，professor of psychology at the University of California，Diem Luu，a former student of the University of California，and Kang Lee，professor at the University Toronto，set out to explore the under-researched phenomenon．They asked US participants in two related studies about parents lying to their children-either for the purpose of promoting appropriate behavior or to make them happy．
              In one of the studies，many parents reported they told their young children that bad things would happen if they didn't go to bed or eat what they were supposed to．Other parents reported inventing magical creatures．One explained，"We told our daughter that if she wrapped up all her pacifiers（橡皮奶嘴）like gifts，the fair would come and give them to the children who needed them．"
              In the other study，the researchers surveyed college students'recollections about their parents'lying and obtained similar results：parents often lie to their children even as they tell them that lying is unacceptable．
              The researchers refer to this practice as"parenting by lying"．"We are surprised by how often parenting by lying takes place，"said Lee．Though Heyman thinks that there are occasions when it is appropriate to be less than truthful with a child，she urges parents to think through the issues and consider alternatives before using lies．
              "Children sometimes behave in ways that are disruptive or are likely to harm their long-term interests，"said Heyman．"It is common for them to try out a range of strategies，including lying，to stop them．However，parents should be concerned about the possible long-term negative consequences to children's beliefs about honesty．"

              (1) The subject of parental lying ______ ．
              A. was not allowed to be researched in the past
              B. attracts little attention because it is common
              C. hasn't got many published results about it
              D. is becoming more and more popular
              (2) What does Heyman think of parental lying？ ______
              A. It is a great parenting strategy．
              B. Parents should think twice before using it．
              C. It usually does more good than harm．
              D. Parents should do something to make up for it after using it．
              (3) Parents usually ______ when their young children don't go to bed properly．
              A. turn off the bedroom lights and play some music
              B. shout at them loudly
              C. shut the door and let them alone
              D. make up some magical creatures to let them believe
              (4) In which part of a newspaper would you most probably find the passage？ ______
              A. Business．
              		B. Education．
              		C. Technology．

              Several times my daughter had telephoned to say，"Mum，you must come and see the daffodils（黄水仙） before they are over．"I wanted to go，but it was a twohour drive from Laguna to Lake Arrowhead．"I will go next Tuesday，"I promise，a little unwillingly，on her third call．
              The next Tuesday dawned cold and rainy．Still，I had promised，and so I drove there．When I finally walked into Carolyn's house and hugged and greeted my grandchildren，I said，"Forget the daffodils，Carolyn!The road is invisible（看不见的） in the cloud and fog，and there is nothing in the world except you and these children that I want to see！"
              My daughter smiled calmly and said，"We drive in this weather all the time，Mum．You will never forgive yourself if you miss this experience．"
              After about twenty minutes，we turned onto a small road and I saw a small church．On the far side of the church，I saw a handlettered sign that read"Daffodil Garden"．
              We got out of the car and each took a child's hand，and I followed Carolyn down the path．As we turned a corner of the path，I looked up and gasped（倒抽气）．Before me lay the most beautiful sight．There were five acres of flowers!But who has done this？"I asked Carolyn．"It's just one woman，"Carolyn answered．"That's her home，"Carolyn pointed to a wellkept Aframe house that looked small and modest in the midst of all that glory．We walked up to the house．On the wall，we saw a poster．"Answer to the Questions I Know You Are Asking"was the headline．
              The first answer was a simple one．"50，000bulbs（鳞茎），"it read．The second answer was，"One at a time，by one woman．"The third answer was，"Began in 1958．"
              I thought of this woman whom I had never met，who，more than fifty years before，had begun-one bulb at a time-to bring the beauty and joy to the mountain top．

              (1) The author didn't go to see the daffodils at first because ______ ．

              A. Delighted．
              		B. Surprised．
              C. Suspicious．

              B. Nothing is impossible to a willing heart．
              C. We can change the world by growing flowers．

              Whether in the home or the workplace，social robots are going to become a lot more common in the next few years．Social robots are about to bring technology to the everyday world in a more humanized way，said Cynthia Breazeal，chief scientist at the robot company Jibo．
              While household robots today do the normal housework，social robots will be much more like companions than mere tools．For example，these robots will be able to distinguish when someone is happy or sad．This allows them to respond more appropriately to the user．
              The Jibo robot，arranged to ship later this year，is designed to be a personalized assistant．You can talk to the robot，ask it questions，and make requests for it to perform different tasks．The robot doesn't just deliver general answers to questions； it responds based on what it learns about each individual in the household．It can do things such as reminding an elderly family member to take medicine or taking family photos．
              Social robots are not just finding their way into the home．They have potential applications in everything from education to health care and are already finding their way into some of these spaces．
              Fellow Robots is one company bringing social robots to the market．The company's"Oshbot"robot is built to assist customers in a store，which can help the customers find items and help guide them to the product's location in the store．It can also speak different languages and make recommendations for different items based on what the customer is shopping for．
              The more interaction the robot has with humans，the more it learns．But Oshbot，like other social robots，is not intended to replace workers，but to work alongside other employees．"We have technologies to train social robots to do things not for us，but with us，"said Breazeal．

              (1) How are social robots different from household robots？ ______
              A. They can control their emotions．
              B. They are more like humans．
              C. They do the normal housework．
              D. They respond to users more slowly．
              (2) What can Oshbot work as？ ______
              A. A language teacher．
              		B. A tour guide．
              C. A shop assistant．
              		D. A private nurse．
              (3) We can learn from the last paragraph that social robots will ______ ．
              A. train employees
              		B. be our workmates
              C. improve technologies
              		D. take the place of workers
              (4) What does the passage mainly present？ ______
              A. A new design idea of household robots．
              B. Marketing strategies for social robots．
              C. Information on household robots．

              A study has showed that the brain makes decisions about 10seconds before a person realizes it．
              Experts involved in the study said that looking at brain activity while making a decision，they could predict the choices the subjects would make，before they realized that they had made a decision．Lead researcher John-Dylan Haynes，a neuroscientist （神经学家）at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig，said that the new findings called into questions for"consciousness"of decisions that people make，and might even challenge ideas as to how"free"people are to make a decision at a particular moment．
              "We think our decisions are conscious，but these data show that consciousness is just the tip of the iceberg，"Nature magazine quoted （引用） him as saying．Thinking the results"quite dramatic"，Frank Tong of Vanderbilt University in Nashville，Tennessee，said that 10seconds is"a lifetime"in terms of brain activity．
              During the study，the brains of 14volunteers were imaged as they performed a decision-making task．The subjects had two buttons before them，each to be operated by a different hand，which they could press when they felt the urge to．They were simultaneously （同时地）shown a stream of letters，which appeared on a screen at half-second intervals （间隔）．The volunteers had to remember which letter was showing when they decided to press their button．
              Upon analysis of the data，the researchers realized that the earliest signal they could catch started seven seconds before the volunteers reported having made their decision．Given the delay of a few seconds in the imaging，they reckoned （估计） that the brain activity could have begun about ten seconds before the conscious decision．The researchers showed that the signals were picked up from a region （区域）called the frontopolar cortex （脑额极皮层），which is located at the front of the brain，immediately behind the forehead．
              While writing about the observations made during the research in his study report，Haynes said that the frontopolar cortex might be the brain region where decisions are started．He also showed that the next step in the research would be to speed up the data analysis so as to enable his team to predict people's choices as their brains would make them．

              (1) The passage tells us that ______ ．
              A. we are aware of our whole process of decision-making
              B. people don't make decisions until they realize it
              C. experts have no way to tell what decision one will make
              D. the decision-making process starts before it is made
              (2) The underlined word"subjects"in Para.2probably refers to ______ ．
              A. the topic of the experts'research paper
              B. the scientific subjects that the experts were studying
              C. the things that experts don't know clearly
              D. the volunteers that the experts worked on for their research
              (3) The underlined sentence"consciousness is just the tip of the iceberg"in Para.4means that ______ ．
              A. our decision-making is conscious
              B. the data contains a lot of information besides consciousness
              C. consciousness is the major part of the data
              D. 10seconds is"a lifetime"in terms of brain activity
              (4) The final purpose of the research ______ ．
              A. is not stated clearly in the passage
              B. is not acknowledged by experts
              C. is to show where decision-making starts
              D. is to analyze the data picked up

              A. the research has been completed
              B. the research was conducted by two experts

              Dear all，
              Please read Professor Hume's email about his next lecture on Rosa Parks．
              Susan Miller
              Secretary              ************************
              Dear Susan，
              Please forward this message to students of my history class．Besides the life story of Rosa Parks in the textbook，the students are also required to read the passage below and some related stories that can be borrowed from the school library．
              Ted HumeThe early experiences of Rosa Parks（1913～2005），long known as the"mother of the civil movement"，were not different from those of many AfricanAmericans at that time．The black woman，however，turned the course of American history in December 1955when she refused to give up her seat on a bus to a white man．"By sitting down，"remarked John Lewis，"she was standing up for all Americans．"
              Among the numerous awards Parks received in her life were the Presidential Medal of Freedom（1996）and the Congressional Gold Medal（1999）．
              Parks died on Oct 24，2005．At St．Paul A．M．E．Church in Montgomery，a large crowd including Secretary of State Condoleezza Rice celebrated her life．Rice said she and others，who grew up when the political activities of Parks held public attention，might not have realized her impact（影响）on their lives，"but I can honestly say that without Mrs．Parks，I probably would not be standing here as Secretary of State．"
              After her casket（灵柩）was placed at the Capitol，U．S．President Bush，members of Congress and ordinary Americans paid their respects．In American history Parks is the first woman to lie in state at the Capitol，a very high regard usually reserved for Presidents of the United States．

              (1) What is the main purpose of Susan's email？ ______
              A. To make arrangements for Professor Hume's class．
              B. To introduce to the students Rosa Parks．
              C. To help the students organize a lecture．
              D. To answer Professor Hume's last email．
              (2) What does the underlined word"forward"mean？ ______
              A. Explain．
              		B. Send．
              		C. Take．
              		D. Read．
              (3) The political impact of Rosa Parks lies in the fact that she ______ ．
              A. helped Condoleezza Rice achieve political success
              B. joined the civil rights movement at a young age

              The Internet brings us many advantages．
              With the Internet，people can send and receive e-mails．On the Internet，people can skim over news．Using the Telnet，the user anywhere on the Internet can log into any other machine on which he has an account．It is possible to use the FTP program to copy files from one machine on the Internet to another．
              But the Internet also brings us troubles．
              Internet use seems to cause a fall in psychological （心理的） health，according to research at Carnegie Mellon University．Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often，the two-year study showed．And it wasn't that people who were already feeling bad spent more time on the Internet，but that using the Net actually seemed to cause the bad feelings．
              Researchers are puzzling over the results，which were completely opposite to what they had expected．They expected that the Net would prove socially healthier than television，since the Net allows users to choose their information and to communicate with others．
              The fact that Internet use reduces time used for family and friends may be the reason for the drop in health，researchers said．Faceless，bodiless"virtual"（虚拟的） communication may be less psychologically satisfying than actual conversations，and the relationships formed through it may not be so deep．Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives．
              "But it's important to remember this is not about the technology； it's about how it is used，"said one of the researchers．"It really points to the need for considering social factors （因素） when you design new inventions．"

              A. the Internet can bring people many advantages
              B. the Internet use may cause psychological problems

              D. we shouldn't use the Internet
              (2) Why are the researchers puzzling over the results？ ______
              A. Because the results were completely different from what they had thought．
              B. Because the Net proved socially healthier than television．
              C. Because the Internet users were all healthier．
              D. Because the Internet users experienced less depression and loneliness．

              C. People who are already feeling bad spend much more time on the Internet．
              D. Relationships formed through the Internet are usually deep．
              (5) What does the underlined part in the last paragraph mean？ ______
              A. What matters is not the technology but how it is used．
              B. This passage is not about the technology but about how it is used．
              C. We should remember to learn about the technology．

              A home computer not only helps children master the old ways of learning，but also opens up possibilities that simply aren't available in traditional education．Some software，for example，allows kids to make decisions and see the results in different situations．The World Wide Web encourages young minds to move easily from link to link，topic to topic．The best software draws children into learning by making them curious-what if I click on this picture，drag this over here，visit that website？
              Knowing how to use a computer also encourages a child's confidence．Kids figure out quickly that computers are powerful，and mastering the machine makes them feel grown-up．In turn，feeling confident on a computer often translates to academic （学术的） confidence．Researchers have found that attitudes toward writing，for example，improve when students write on a computer．
              Perhaps most importantly，computers can enrich family life．Forget the idea that computer kids are separated．Children like to use the computer with adults and other kids，asking questions and comparing results．"The Internet is a unique opportunity to bring resources home，"notes Susan Haugland，PhD，Cape Girardeau，Mo．，author of Computers and Young Children：A World of Discovery．
              Although the benefits of computers are real，they have disadvantages，too．Kids can lose their way，wasting hours on mindless software or violent games．Just as parents have always helped children make good choices about everything from friends to food，books to TV，now we must make sure they get the best out of computers．

              A. the disadvantages of children's using computers
              B. the advantages of children's using computers
              C. the development of computers

              (2) Which of the following is NOT an advantage of a home computer？ ______
              A. It provides new ways of learning．

              C. It can enrich family life．
              D. Kids can play violent games on it．
              (3) What effects do computers have on family life？ ______
              A. They reduce the connection between family members．
              B. They destroy the relationship between parents and kids．
              C. They provide more opportunities of communication．
              D. They make all the family members study together．
              (4) According to the last paragraph，we can learn that we should ______ ．
              A. let children use computers freely
              B. forbid children to use computers in their spare time
              C. permit children to use any software they like

              Your gestures and how you hold yourself during a presentation convey as much as words might．You should face the audience rather than turn your back to them．Here are some more tips．
              Don't gaze down．Never look away from your audience．Never lose eye contact with those who have come to hear you speak．Eye contact helps you connect with people and win their trust．
              Don't play with your hands．Playing with your hands is distracting．Unless you are pointing to something in your presentation or making a big movement，keep your hands by your side．
              Don't turn away from the audience．"Nobody wants to look at your back，"says Rosenthal，CEO of Communispond in East Hampton，NY．And you often can't be heard if you are speaking to the screen．Rosenthal likes the"think，turn，talk"method．Look at an item you are discussing to gather your thoughts，turn to look at the audience，and then start speaking．
              Don't roll your eyes．You don't want to distract your audience with visual effects like rolling your eyes．This is especially true when you're responding to questions，or comments，and you don't want to appear impatient．
              Don't chortle （咯咯笑）．"Nobody wants to see a clown performing unless，of course，you're at the circus，"says Rosenthal．
              Don't haw （支吾）．Do your best to avoid"filler"words．Keep the"um"，"you know"and"like"out of your speech．
              Don't look messy．You should be neat and organized．Dress for the environment．
              So what should you do？Smile．Stand．Make eye contact．Open your arms．Speak loudly．Rosenthal says，"Plan for success．Look good，sound good，and know your material．"
