              No one can change the weather． Nobody can control the weather． But if we read correctly the signs around us， we can tell what the more important changes in the weather will be． This way of telling what the weather will be like on the following day or two is called weather forecasting．
              For many centuries and in all countries， people have studied the weather and tried to make weather forecasting． Rings around the sun are a sign of coming rain． Many people feel their joints（关节） hurt in their bones if wet weather is coming． Some birds fly high if fine weather is coming， but they fly near the ground if rainy or stormy weather is on the way． It is probably because of the insects （昆虫） which they are hunting that they fly low． If you see a rainbow （彩虹） during rainy weather， this is a sign that the weather will become clear and fine． Such rainbows come in the evening． If the stars twinkle clearly at night， then fine weather will continue． If a fog appears in the morning just above a river， then the day will be warm． If the sunset is mostly red in color， then the following day will be fine． If a rainbow appears in the morning， rainy weather will probably come． Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting．
              (1) Which is true about weather forecasting？ ______
              A. Weather forecasting is a recorder about the weather on the following day or two．
              B. Weather forecasting is a way of telling what the weather will be like．
              C. Weather forecasting is a sign of coming rain．
              D. People can change the weather．
              (2) According to the passage， people's joints ache ______ ．
              A. is a sign of coming rain

              C. because they are ill
              D. because of the insects
              (3) The birds fly high and the stars twinkle clearly is a sign that the weather will ______ ．

              How does a big company like Dannon come up with a new kind of food for kids？ What's the science that goes into it？ To find the answers to these questions， I visited the Dannon Innovation Center， in New York．
              Greek-style yogurt is becoming more and more popular with adults． But Dannon USA did surveys and found that while parents are eating Greek yogurt， their kids aren't． "We didn't know why，" said Dannon's Michael．" Kids told us that Greek yogurt was too thick and too sour．"What did Dannon do with this information？ They looked for ways to make the yogurt interest kids．
              Making yogurt is simple， explained Dr Thierry Saint-Denis， Dannon's director "Talk milk． Mix in bacteria． Keep it warm for a few hours． Then a natural chemical process called fermentation turns the milk into yogurt．"
              What makes yogurt "Greek"？ it's thicker than usual yogurt， and less sweet． Dannon's scientists looked for special bacteria that would make their Greek yogurt feel less thick and taste sweeter to kids． Dr Saint-Denis said that after many tests， they found those bacteria． But he couldn't tell TFK which bacteria： they are trade secrets．
              Finally， I got to taste the finished Greek-style yogurt． Out of the five new flavors， my favorite was Mixed Berry Half-Pipe． It is neither too thick nor too sour．

              I always felt sorry for the people in wheelchair． Some people，old and weak，cannot get around by themselves． Others seem perfectly healthy，dressed in business suits． But whenever I saw someone in a wheelchair， I only saw a disability，not a person．
              Then I fainted at Euro Disney due to low blood pressure． This was the first time I had ever fainted，and my parents said that I must rest for a while after First Aid． I agreed to take it easy， but as I stepped toward the door，I saw my dad pushing a wheelchair in my direction! Feeling the color burn my cheeks，I asked him to wheel that thing right back to where he found it．
              I could not believe this was happening to me． Wheelchairs were fine for other people but not for me，as my father wheeled me out into the main street，people immediately began to treat me differently．
              Little kids ran in front of me，forcing my father to stop the wheel chair suddenly． I felt sad as I was thrown back and forth． " Stupid kids一they have perfectly good legs． Why can't they watch where they are going？" I thought． People stared down at me， pity in their eyes． Then they would look away，maybe because they thought the sooner they forgot me the better．
              "I'm just like you! " I wanted to scream． "The only difference is you've got legs，and I have wheels． "
              People in wheelchairs are not stupid． They see every look and hear each word． Looking out at the faces，I finally understood： I was once just like them． I treated people in wheelchairs exactly the way they did not want to he treated． I realized it is some of us with two healthy legs who are truly disabled．
              (1) The author once ______ when she was healthy．
              A. laughed at disabled people
              B. imagined herself sitting in a wheelchair
              C. looked down upon disabled people
              D. saw some healthy people moving around in wheelchairs
              (2) The experience of the author tells us that ______ ．
              A. life is the best teacher
              B. people often eat their bitter fruit
              C. life is so changeable that nobody can foretell
              D. treating others in the way you want to be treated
              (3) Which is the best title for this passage？ ______
              A. How to Get Used to Wheelchairs
              B. The Wheels Are as Good as Two Legs
              C. People with Two Legs Are Truly Healthy

              In nature， you may see many insects and animals of different colors． Have you ever wondered why Locusts are super delicious food for birds， but it is not always an easy job for birds to catch them． It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies． The reason is that the colors of locusts change with the colors of crops（庄稼）． When crops are young， locusts look green． But when autumn comes， locusts change to the yellow and brown color as crops do．
              Brown bears， tigers and other animals move quietly through forests． They can't be seen easily by their enemies． This is because they have colors similar（类似的） to the trees． For the same reason， polar bears that live on a land of snow and ice are white． Butterflies and bees living among the flowers are colorful like flowers． Soil（土壤）insects are mostly dark-colored and they live under the soil in a dark and wet environment． However， insects with colors different from plants can easily be found and eaten by others． So in order to survive， they have to hide themselves in the daytime and appear only at night．
              Have you ever noticed some even stranger acts？ The ink fish（墨鱼） in the sea can send out some very black ink when it faces danger． As the ink spreads over（散开） ， its enemies（敌人） will find themselves suddenly in a dark world． At the same time the ink fish immediately swims away． That is how it keeps itself safe though it is not strong at all．

              (1) It is not easy for birds to catch locusts because ______ ．
              A. locusts are good runners

              Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you. Companies like Google and Tesla have been designing and testing these cars, and the technology is there.

              So how? The cars have sensors（感应器）all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems（卫星导航系统）are used so the car knows how to get where you want to go. All you have to do is type in the address! Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.

              Sound like your idea of heaven (天堂)? Sitting back, looking out of the windows and even watching a film or reading a book while ‘driving’ would be possible with this new technology. You wouldn’t have to worry about remembering directions to where you’re going. In addition, computers would also drive more safely than people — they would obey the rules and have quicker action times when in dangerous situations.

              However, there are many drawbacks of driverless cars. Computers would have difficulties making ethical (道德) decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly and potentially kill the car’s passengers? Moreover, I personally find driving fun –I’d miss never driving a car myself. There would also be many other decisions to be made –should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?

              I’m not certain I’d want a driverless car – but it’s only a matter of time before they’ll become more affordable and popular on our roads.

              (1) When using a driverless car, you need only ________.

              A. read the road signs carefully                       
              B. check the cameras

              C. put the address into the computer          
              D. remember the directions

              (2) The third paragraph mainly tells us about the ________ of driverless cars.

              A. instructions            B. standards               
              C. advantages D. tests

              (3) The underlined word “potentially” in Paragraph 4 means “________“.

              A. possibly               B. successfully      
              C. especially       D. naturally

              (4) What’s the writer’s opinion about future driverless cars?

              A. They’ll cause more accidents.                
              B. They’ll be less expensive.

              C. They’ll use less energy.                      
              D. They’ll run much faster.

                  At night, you fall asleep while listening to beautiful music. In the morning, you are   (1)   up by the singing of birds outside. You can enjoy all of these things because of one important organ(器官)－the ears. March 3 is Ear Care Day. It helps us remember the   (2)   of our ears and encourages us to take good care of them. You may wonder: how do the ears   (3)   ? The ear has three different parts: the outer ear, the middle ear, and the inner ear. The outer ear is the part you can see. It collects   (4)   around you. The sound then travels down to the middle ear, the inner ear and then to your brain.

                  Your ears never stop working, even   (5)   you are asleep! Thatˈs why you may sometimes wake up suddenly in the middle of the night－your brain   (6)   something, but you donˈt know what it was, since you were asleep.

                  But ears do more than hear. They help you keep your balance, too. In the inner ear, there are organs that are filled   (7)   liquid(液体)and covered in small hairs. When you move your head, the liquid and hairs move, too. They send   (8)   to your brain about the position of your head.

                  More surprisingly, ears even help with   (9)   food. If something happens to your ears, you may have a hard time telling different tastes, according to the website of Peopleˈs Daily.

                  The ears are   (10)   important organs. Everyone should make sure to protect their own ears as well as they can.

              (1) A. taken              B. cheered           
              C. woken              D. dressed

              Taking away a cityˈs rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we canˈt eat or use. If we kept these things we would soon have a mountain of rubbish.

              In some cities the rubbish is collected and taken outside of city to a dump. Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs and other places.

              To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish---filled land. Finally, a house or a school may be built there, and then youˈd never know that this had once been an old rubbish dump.

              In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called hurnus, which looks like black earth. It is rich with the kinds of things that feed plants and help them grow.
