At first, I thought Lucy was able to ride her bike along the track, but she quickly found that her bike was too low to the ground and kept getting stuck on top of the bumps.Lucy looked at me with fear because she was still a biking newbie. I tried to encourage her, too, but really, I was thinking — this is going to be a disaster. Not because I thought she would get hurt. More because I thought she wouldn't be able to pick up enough speed to balance, then get really discouraged, and give up quickly. I imagined her throwing her bicycle to the ground and then crying all the way home.But I was only half right. Lucy did have a lot of trouble riding the bike. She couldn't find her balance. She fell many times. At one point, she almost started crying because other younger kids were getting angry that she was slowing everyone else down. But she did not give up. She kept picking herself up and trying again. She even took the bike off the track and into the main park to practise pushing off and picking up speed on a flat ground. When she felt more confident, she came back. Then she did it over and over again until she finally reached her goal of going around the whole track without falling once. Then she didn't want to leave and everyone was cheering her on.This was not a day that ended in a disaster. It was a day when Lucy learnt that perseverance (坚持不懈) pays off.11.Why was Lucy taken to the park last weekend?A.To play with other kids.B.To discover a track for fun.C.To find her speed was too slow.D.To ride her bike along the track.12.What can we infer from the underlined sentence “this is going to be a disaster” in Paragraph 2?A.Lucy would get hurt and cry all the way home.B.Lucy would fear to ride the bike and get discouraged.C.Lucy would lose balance and slow the younger kids down.D.Lucy would have trouble riding the bike and give up soon.13.What did Lucy take the bike into the main park for?A.Being cheered on by everyone.B.Getting practice in an easier way.C.Feeling more confident and coming back.D.Reaching her goal of riding the bike at once.14.Which one is the right order of the events?a. Lucy fell and got up lots of times.b. Lucy picked up speed on a flat ground.c. Lucy found her bike was too low for the bumps.d. Lucy rode her bike around the whole track without falling once.A.a-b-c-d.B.c-b-a-d.C.c-a-b-d.D.a-c-b-d.15.What is the best title of the passage?A.Playing in the Park Is FunB.Perseverance Pays offC.Don't Be Afraid of Fall inD.Riding Bikes Is Art.阅读理解As children patients sometimes require long hospital stays, they often miss school or have little communication with their friends. This can lead to a sense of loneliness. That's why the global nonprofit(不盈利的) organization, TEACH, which stands for Together Educating All Children in Hospitals, has appeared.For the past seven years, students from 15 universities have volunteered in about 30 hospitals worldwide to bring an educational program to sick children, which helps develop their interest in science and nature. And most importantly, they have raised the spirits and improved the confidence of thousands of sick children.Isaac Snyder, TEACH Executive Director, said that it's heartwarming to watch the older students help the younger patients with some of the more advanced activities, such as engineering experiments. Unlike other programs, the program of TEACH makes children experience more than just reading coloring books, watching movies or playing online games. It teaches kids how science can be used for their own illness. Besides inspiring kids to see science in a new light, it helps kids understand the diseases that are putting them in the hospital. "It has a great effect on kids. And it can reduce their fears and help them have a positive attitude towards science," Isaac explained.Isaac knows TEACH can also inspire volunteers to start a career in medicine. Take Isaac as an example. Though Isaac started out as just a volunteer, he finally studied medicine and made a difference to the lives of children patients. When people asked Isaac what he had seen in the patients' spirits as those patients joined in the program of TEACH, he shared, "The parents told the volunteers that this was the first time their children had smiled in days, and they were so happy. "16.What is TEACH?A.hospital room.B.A travel program.C.A medical technology.D.A volunteer organization.17.What is the greatest achievement of TEACH for children patients?A.To take care of them scientifically.B.To encourage them to be hopeful.C.To offer them medical education.D.To help them understand hospitals.18.Which is the most important in helping children become less afraid of illness?A.Making friends with them.B.Telling them funny stories.C.Playing online games with them.D.Giving them knowledge of diseases.19.Which of the following can best describe TEACH's program?A.Easy and relaxing.B.Boring but important.C.Creative and successful.D.Expensive but worthwhile.20.What is the best title for the passage?A.Sick children can have a lot of fun in the hospitalB.How TEACH has an effect on volunteers' careersC.How to reduce sick children's loneliness and sadnessD.TEACH uses an educational program to help sick children.阅读理解When we hear the word "virus", we naturally think of something dangerous. However, some viruses coexist (共 ) with us and we can even make good use of some of them, according to recent studies.Biologists suggest that 380 trillion viruses are living on and within your body right now. These viruses are collectively known as the human virome (病毒组). Some can cause illness, but many simply coexist with you.It appears that our viromes begin to accumulate when we are born. Studies have shown different viruses in the babies' bodies shortly after birth, suggesting that they probably come from the babies' mothers. The viromes grow in number as the kids grow up. They are not likely to change during adulthood."The virome looks like a partner that can influence our daily lives positively as well as negatively. We could even use the virome to improve our own health," said David Pride, an expert from the US.One way is to use parts of viruses to cure diseases. Researchers in the US have got a chemical from a virus that kills bacteria (细菌) found in patients.The other way is to develop viruses' value. Many viruses in our viromes infect bacteria. When the viruses move around the body, some arrive at the surfaces of our bodies such as the nose, throat and stomach. Viruses cannot divide and produce exact copies of themselves there, but they can wait for a bacteria to arrive. This process makes it possible to prevent us from getting certain diseases.21.What does the underlined word "accumulate" in paragraph 3 mean?A.produce matters.B.create problems.C.increase the quantity.D.examine the body.22.Which of the following statements is NOT TRUE?A.Viruses even appear in the body of a baby.B.Not all viruses cause illnesses in our body.C.There are less than 380 trillion viruses in a baby's body.D.The number of viromes grows largely in the body of adults.23.How can viruses benefit people?A.They help people avoid certain diseases.B.They have a chemical that can cure cancer.C.They can copy themselves to kill harmful bacteria.D.They can turn harmful bacteria into a harmless one.24.What is the author's main purpose in writing the text?A.To describe how viruses come into being.B.To explain how viruses can be very useful.C.To show the importance of human viromes.D.To introduce our relationship with viruses.25.Where is this text most likely from?A.A science fiction.B.A health guidebook.C.A technology newspaper.D.A biology magazine.三、阅读填空（共5小题，每小题1分）.请阅读下列短文，并从下列方框里的六个句子中选择五个还原到原文中，使原文的意思完整、连贯。

What will students learn if they take the online course?A. The way to write a resume．B. The way to put an advertisement．C. The skills of talking with others．D. The skills of improving reading．2. Who is the online course intended for?A. Trainers．B. Interviewers．C. Job seekers．D. College students．3. Which ofthe following best describes the online course?A Cheap． B. Practical． C. Long-standing． D. World-class．BHave you ever noticed that some people can eat what they want and stay in shape, while others carefully watch what they eat and still put on weight? How annoying! However, scientists are beginning to believe that some people get the ability to stay thin from their parents.Scientists say that when some people eat, their bodies will naturally store the excess energy from food as fat. These people gain weight if they eat more than they need each day. Meanwhile, other people eat more than they need but their bodies are able to “burn off” the extra food without making fat, so they rarely have weight problems.To show that this is true, scientists have experimented on laboratory mice. They gave the mice a special diet with a lot of fat. Some mice gained weight while the other mice stayed thin, even though both groups of mice ate the same amount of food and got the same amount of exercise. Scientists concluded that weight gain seemed to be influenced by genetic (基因的) factors. They also believe they have now identified the genes that may cause this tendency. These genes, according to the scientists, get passed down the generations. Armed with this knowledge, they believe it may be possible to develop medicines thatcan target the genes and stop people from gaining weight.The study of weight gain is becoming more important as the numbers of people who are overweight continues to grow. In theUnited States, over seventy percent of the population have weight problems. This means they are at risk of illness such as high blood pressure and heart disease.Current medicines for weight control do not work very well because they can have serious side effects, such as heart problems. However, it takes a long time to develop and thoroughly test new drugs. Therefore, despite this breakthrough in the study of weight-loss drugs, scientists and health professionals all agree that currently the best way to control weight gain is to have a healthy, balanced diet and an active lifestyle with daily exercise. This will not only help people avoid becoming overweight, but also help them stay healthy and energetic.4. According to the scientists, some people ________.A. are able to stay thin because of genetic factorsB. can eat what they want and stay healthy foreverC. usually keep doing exercise to lose their weightD. don’t eat anything every day but still put on weight5. Some people don’t need to worry about weight problems because ________.A. they eat many vegetablesB. they eat less than othersC. they don’t store any energy from food as fatD. they can burn off the extra food without making fat6. What can we learn from the passage?A. Fewer people will have weight problems in the future.B. People with weight problems may suffer from heart trouble.C. We now have good medicine for people with weight problems.D. The result of the experiments on mice and humans are different.7. What does the last paragraph imply?A. Current medicine solve weight problems well.B. We should exercise regularly and eat properly.C. Taking exercise every day may cause heart problems.D. Testing new drugs is hard because of the side effects.C“They’re harming your brain.” “They’re ruining your eyes.” “They’re turning you into a violent person.” The words said publicly against video games are so common, but are these worries founded on actual science? Countless studies have offered different opinions on whether video games are bad for you. We’ve rounded up the most notable reports and studies below, so you can weigh up the evidence for yourself.In 2013,psychologist(心理学家) Simone Kuhn studied the influences of spending long hours on video games on the brains of young adults and found that several areas became bigger than before. These areas are connected with highercognitive functions(认知功能), memory formation andfinemotor(精细运动) function.Last year, psychologists said that video game players who favour violent games are more likely to be violent when offline. Dr. Mark Appelbaum of the American Psychological Association said that there was a relation between violent video game use and increases in violent behaviour.Dr. Daphne Bavelier is an expert in the field of Brain & Cognitive Sciences. Bavelier presented the audience with a colour-word test, where non-gamers are easily puzzled by the test, and those who spend long periodsplaying on their computers are more likely to pass the test with flying colours.“Actually, those video game players have many other advantages in terms of attention,” said Bavelier, “and one part of attention which is also improved for the better is our ability to follow the movements of objects.”“So, in a sense, when we think about the influence of video games on the brain, it’s very similar to the influence of wine on the health. There are some very poor uses of wine. There are some very poor uses of video games. But when drunk in reasonable amounts, and at the right age, wine can be very good for health,” said Bavelier.8. What can be learned from Simone Kuhn’s study？A. Video games make you happier.B. Video games make your brain grow.C. Video games play a key role in memory.D. Video games teach you how to learn fast.9. What was Dr. Mark Appelbaum’s attitude towards video games？A. He was against them.B. He was hopeful of them.C.He was in favour of them.D. He was uncertain about them.10. Which of the following may Dr. Daphne Bavelier agree with？A. Video games fix attention problems.B. Video games make kids do well in exams.C. Video games encourage violent behaviour.D. Video games help increase colour knowledge.11. Why are the uses of wine mentioned in the last paragraph？A. To remind people to avoid video games.B. To show the disadvantages of video games.C. To help people learn more about video games.D.To ask people to make good use of video games.DWhat will future schools look like in 100 years? Imagine future schools in which students are totally engaged in a class. They are concentrating on working together to solve real-world problems. They are self-driven and are coming up withamazing ideas on the spot. They are concerned with each other’s well-being as part of a team. Their concerns reach far beyond the classroom to others all over the globe.The school of the future will be an amazing melting pot of different peoples coming together to solve real-world problems.Will they even be called “schools” in the future?The teacher-student relationship is changing. Teachers are acting more as helpers rather than keepers of all knowledge. Students are driving their own education to the path that they feel best fits them. In the future, employers may not be as concerned with a diploma. They’ll look more at cases and examples of how students contribute to solving real-world problems. They’ll want to know how well they work in a team.What will problem-solving look like in the future?Information from the Internet is accessible everywhere and at unimaginable speeds. Kids are connected to news around the world in real time. Imagine someone could put out a request to the global community to help solve an issue in their own community! Classes can adopt an issue and work with other classes around the world in real time to create solutions.What will information look like in the future?It’s already everywhere. Users can get flooded by the constant flow of information. The need to understand what is true and what is not is important. The flipped classroom (翻转课堂) has already completely changed lecture-based lessons. It presents interesting content to students before they even come to class. They can access the Internet as many times as they want to review the lessons.12. What is the key message of the first paragraph?A. The things students will do in the future school.B. The situation where students will be in the future.C. The attention students will pay to in the classroom.D. The methods students will use to study in the classroom.13. What will be thought highly of when students solve real-world problems?A. Respect.B. Patience.C. Teamwork.D. Concern.14. What can we infer from the fourth paragraph?A. Teachers encourage students to develop leadership.B Students are really relaxed with their heavy study.C. The employers value students’ diplomas most.D. Students have the right to choose the most suitable lessons.15. What’s the purpose of the flipped classroom?A. To help students to improve the problem-solving ability.B. To provide the lessons for students to study before or after class.C. To help students to keep in contact with the outside world.D. To help students to understand the most difficult content.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
