              Every day，people come into contact with thousands of chemicals．These chemicals are said to be harmless to human health．In fact，the chemicals are considered so safe that we wash with them．We put them on our bodies and even our faces．Other chemical products are used throughout our homes．
              By the time you walk out of your front door，you have already been exposed to thousands of chemicals．
              On its own，each chemical seems harmless．But in combination with other chemicals，they may become deadly．That is the finding of a two-year study by a high-profile（高调的）task force of scientists．The task force was told to investigate the cancer-causing possibility of chemical mixtures．
              Linda Gulliver was one of the 174 scientists on the task force．Their job was to study the cancer-causing potential of 85 chemicals．All 85 are said to be common in the environment．
              Ms．Gulliver explains that chemicals have the potential or ability to form dangerous mixtures．Even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products．
              Working in groups，the scientists explored how different chemical mixtures could lead to cancer．Ms．Gulliver's team looked at the ability of different combinations to support the increase of malignant（恶性的）human cells．
              She says the current way to identify whether chemicals cause cancer is to test them one at a time．This method leads，she adds，to a long list of supposedly"safe"chemicals．She and her team say that approach needs to change．
              "We definitely need certain research…to find out what mixtures of chemicals would be more harmful than others； what groups of chemicals，when together，would produce more harmful effects．And at the moment，that is not known．"
              An estimated one in five cancers has been linked to chemical exposure．It may turn out that the cancer-causing villain（恶棍）is not a single chemical at all．

              (1) What effect may one single chemical have on us according to the text？ ______
              A. It may destroy our body．
              B. It may not cause danger to us．
              C. It may let us suffer from cancer．
              D. It may let our body make a change．
              (2) What can we learn about Ms．Gulliver's research？ ______
              A. She has found 85 cancer-causing chemicals．
              B. She has found reasons for five kinds of cancers．
              C. She has found that only one chemical can cause cancer．
              D. She is not sure what mixtures of chemicals are more harmful．
              (3) According to the text，we can infer that the study ______ ．
              A. is just wasting time and money
              B. is still in need of great efforts
              C. will cause panic in public
              D. will be resisted by the public
              (4) What is the best title for the text？ ______
              A. Mixtures of Safe Chemicals May Cause Cancer
              B. Being Exposed to One Chemicals Is Dangerous
              C. How Mixtures of Safe Chemicals Come into Being？
              D. What Is the Real Cause For Cancer？

              When I first started university，I remembered hearing about bone marrow（骨髓）donation during Freshman's Week．Some students volunteers from a group called Marrow tried to convince me to attend an event so I could learn more about it．The word"bone"immediately made me think that donating would be a painful procedure，so I refused． Back then，there was no way I could have known three years later，I would be one of the many people that desperately needs a bone marrow donor to save their lives．
              I am currently waiting to be matched with a donor and if I am lucky enough to find a good match，it will be this lovely stranger that saves my life．I received my cancer diagnosis in June．It is only at that time that I realized how ignorant I had been about the bone marrow donation process．
              The process of donating stem cells is actually very simple．In 90% of cases，donors are asked to donate their blood stem cells，the other 10% will give their bone marrow．Lots of donors say that both these things are virtually pain free，and nothing to be scared about．Being a bone marrow donor should be something to be proud of，as every donor has an opportunity to save someone's life!
              At the moment I know that the doctors are busy searching for a match，I simply live every day in the hope that there will be a donor right for me．If I have an opportunity for life，I won't waste it．
              When I was a first year at university，I made the mistake of walking away from becoming a stem cell donor．Please don't make the same mistake that I did．There are so many people out there，including myself，that need your help； and by undergoing a simple，pain-free procedure，you could have the chance to proudly say that you saved someone's life．

              (1) Why did the author refuse to learn more about bone marrow donation before？ ______
              A. Because she could get nothing from it．
              B. Because she thought that donating would be painful．
              C. Because she had known nothing about it．
              D. Because she was in poor health．
              (2) What can we learn from the underlined sentence in paragraph1？ ______
              A. The author was concerned about others．
              B. The author was confident about the bone marrow donation．
              C. The author needs the bone marrow donation now．
              D. The author donates her bone marrow to save others．
              (3) The author needs the bone marrow because she got ______
              A. cancer
              		B. headache
              		C. flu
              		D. high blood pressure
              (4) The author told us her story to ______
              A. show us the experience of her college life．
              B. explain the cause of her cancer．
              C. recall her painful past．
              D. encourage people to be a bone marrow donor．

               A man hated his wife’s cat and decided to throw it away. One day, he drove it over one mile from his home and left it in a park.

              But when he got home, he saw that his wife was playing with the cat.

                 The next day he drove the cat about three miles away. He put the cat out of the car and went home. Driving back his driveway（私人车道）, the cat was there already.

                 The man keep taking the cat further and further away and the cat would always get home before him. At last he decided to drive more than ten miles away. He turned right, then left, past a bridge, then right again and another right until he thought he was far enough from home and left the cat there.

                 Hours later the man was still driving home. He was lost! He called home and asked his wife,“Jen, is the cat there?”

                “Yes,” his wife answered,“why do you ask?”

                 The man answered,“Put it on the phone. I’m lost and need directions.”

              Dear Alfred，

                     I want to tell you how important your help is to my life.

                     Growing up, I had people telling me I was too slow, though, with an IQ of 150+ at 17, I’m anything but stupid. The fact was that I was found to have ADHD (注意力缺陷多动障碍). Anxious all the time, I was unable to keep focused for more than an hour at a time.

                     However, when something did interest me, I could become absorbed. In high school, I became curious about the computer, and built my first website. Moreover, I completed the senior course of Computer Basics, plus five relevant pre-college courses.

                     While I was exploring my curiosity, my disease got worse. I wanted to go to college after high school, but couldn’t. So, I was killing my time at home until June 2012 when I discovered the online computer courses of your training center.

                     Since then, I have taken courses like Data Science and Advanced Mathematics. Currently, I’m learning your Probability course. I have hundreds of printer paper, covered in self-written notes from your video. This has given me a purpose.

                     Last year, I spent all my time looking for a job where, without dealing with the public, I could work alone, but still have a team to talk to. Luckily, I discovered the job—Data Analyst—this month and have been going full steam ahead. I want to prove that I can teach myself a respectful profession, without going to college, and be just as good as, if not better than, my competitors.

                     Thank you. You’ve given me hope that I can follow my heart. For the first time, I feel good about myself because I’m doing something, not because someone told me I was doing good. I feel whole.

              This is why you’re saving my life.

              Yours,

              Tanis

              It was Mother’s Day morning last year and I was doing my shopping at our local supermarket with my five-year-old son, Tenyson. As we were leaving,we found that only minutes earlier an elderly woman had fallen over at the entrance and had hit her head on the concrete.Her husband was with her,but there was blood everywhere and the woman was embarrassed and clearly in shock.

              Walking towards the scene,Tenyson became very upset about what had happened to the couple.He said to me,“Mum,it’s not much fun falling over in front of everyone.”

              At the front of the supermarket a charity(慈善)group had set up a stand selling cooked sausages and flowers to raise funds.Tenyson suggested that we should buy the lady a flower.“It will make her feel better,”he said.I was amazed that he’d come up with this sweet idea.So we went over to the flower seller and asked her if we could buy a flower for the lady to cheer her up.“Just take it,”she replied.“I can’t take your money for such a wonderful gesture.”

              By now paramedics(救援人员)had arrived,and were attending to the injured woman.As we walked up to her, my son became intimidated by all the blood and medical equipment.He said he was just too scared to go up to her.

              Instead I gave the flower to the woman’s husband and told him,“My son was very upset for your wife and wanted to give her this flower to make her feel better.”

              At that,the old man started crying and said,“Thank you so much,you have a wonderful son.Happy Mother’s Day to you.”

              The man then bent down and gave his wife the flower, telling her who it was from.Though badly hurt and shaken,the old lady looked up at Tenyson with love in her eyes and gave him a little smile.

                  February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.

                  On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals(花瓣)! This is what you see on Valentine’s Day, a day named after Valentine who was a priest（牧师） in the third century Rome. When the emperor(皇帝) decided that single men could become better soldiers than those with wives, he didn’t allow marriage.

              But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter which he signed “from your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint(圣徒), as well as becoming one of history’s most romantic characters.

              Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share the spirit of St. Valentine.

              (1) Why did the emperor in Rome not allow marriage in his country?

                  

              A. Because there were few women in his country at that time.

              B. Because he wanted to control the birth rate.
              C. Because there wasn’t enough food for so many people.
              D. Because he thought men without wives could be better soldiers.

              (2) Valentine was put into prison because           .

                

              A. he killed one of the soldiers                                  
              B. he stole a lot of food

              C. he didn’t obey the emperor’s order                        
              D. he didn’t want to be a soldier

              (3) The last paragraph mainly tells us         .

                

              A. students in China send cards to their teachers

              B. it is a good idea to celebrate Valentine’s Day in China
              C. Valentine’s Day is also popular in China now
              D. it is interesting to celebrate Valentine’s Day in China

              (4) The best title for this passage should be        .

                   

              A. Valentine’s Day                                           
              B. A Brave Priest

              C. Valentine’s Day in China                                    ​
              D. A Romantic Man

              My daughter Kelly is a cautious person．She needs to warm up to situations，and is hesitant to try new things．When with close friends，she becomes a leader who laughs loudly and chants，"Girls rule，boys drool （流口水）"But when that comfort zone is not around her，she is shy and nervous．
              This had been challenging for me at times．"Shy"is not a word that I think has ever been used to describe me．But this has been a year of"firsts"for my girl that has filled her with a new sense of confidence．This year she moved to lap lane in swimming where she was preparing for a swim team．This year she learned to ride a bike without training wheels．And this year she completed her first kids'triathlon （三项全能）．
              On Saturday，with a thunderstorm coming soon and my son's birthday party later in the day，we all went out in the dark of the morning for Kelly to participate in her first triathlon．We practiced transitions （过渡） from swim to bike to run with her，we got all the equipment she'd need，and we kept talking about the race．But as we waited the two hours for the older kids to finish before her turn，she held my leg a little harder and told me she loved me many times．She was nervous but trying to keep it together．
              And then it was her turn．From the second she jumped into the water，my face lit up．My daughter transformed into the most confident human being I had ever seen．She dominated （主宰） that swim，won that bike ride and ran to the finish with the biggest smile on her face．
              I can honestly say that I never felt so proud of someone in my entire life．It wasn't because she did a sport or anything like that．It was because she was afraid of something and conquered （克服） that fear with confidence and a fire I hadn't seen before．
              All day I would find myself just looking over at her and smiling．She might be wearing the finalist medal but I felt like I won that day．I won the chance to see my girl shine．
              Shine on，sweet baby．
