If you want to do a flat ride, you may go on _A.Sunday, October 29 , 2017B.Wednesday, November 1, 2017C.Sunday，October 22, 2017D.Friday, November 3，2017BMy professor gave me an assignment (任务)that is going to take at least twenty hours to complete—community (社区)service.We are all part of a community. The quality of a community is largely dependent on how citizens treat each other，So go out into your communities and do a service in a way that you don’t get paid. You might be surprised what can happen in those twenty hours，” said the professor.After doing some research, I found an after-school tutoring(辅导）program for a fourth-grade boy named Steven. He was small for his age，wore glasses and was a Harry Potter fan. He was a little on the quiet side for the first few weeks，but it was obvious that he was a very bright boy. He didn't need a tutor as much as he needed a friend. It seemed that his classmates mostly ignored him.When I started, I only planned to complete the required hours for my assignment. But when the hours were done，I liked Steven. And I could tell that he had already grown attached(依恋)to me.As the end of the school year came, Steven said, “I don't want the school year to end. Because when the school year is over, I won't see you any more. ”I had signed an agreement stating that at the end of the school year I wouldn't have a relationship with the child I tutored. I'm going to miss you, too, Steven, but I promise I will never, n ever forget you. ”It took me some time to get used to not heading over to that old elementary school and seeing that sweet，smiling boy waiting for me. But then I realized I had my own sittings (兄弟姐妹).I had been so busy being an adult that I really didn't pay any attention to them at all，It was time to change that.24.Why did the professor ask his students to do community service?A.To develop their spirit of working hard.B.To judge their ability of communication.C. To increase their sense of helping others.D.To test their belief in the service.25. According to the writer, Steven .A.looked like Harry Potter with his glassesB.was like a pet of his teachers at schoolC.had few words in class most of the timeually felt lonely at school26.What did the writer promise to do before tutoring Steven?A.Not to keep in touch with him Later.B.To remember the good days with him.c.To continue the service if it is necessary,D.To pay attention to his progress forever.27.How did the community service change the writer?A.She realized the importance of the community.B.She started to care about her family members.C.She became a volunteer in the community.D.She spent most of her time at homeCEven if all goes well for you in high school—you keep your grades up，join in activities and never fall on your face in front of everyone in the dining hall—that time of life still can be hard. There are so many subjects to learn and social activities to join in. But of all those challenges, making good friends might be the most important.Researchers found that those with strong, close relationships with their friends at age 15 were more likely to be healthy and happy later.They have more self-worth(自信）and less anxiety and depressive symptoms(抑郁症状）by early adulthood(人）.Importantly, popularity—explained as Lots of people liking you generally, but not closely—wasn't found to have the same advantage as close friends.The researchers followed the 169 teens every year for ten years. They got data in real time from these teens as they grew.Importantly，too, the teens were 58 percent whites, 29 percent African American, and 8 percent of different faces, and with families of $40,000 to $59,999 a year.“Our study proves that forming strong close friendships is likely one of the most important pieces of the being well-liked by a large group of teenage social experience，” said Joseph Allen.Why does this matter? Because, as Allen wrote, “For high schoolers,people cannot replace developing deep and supportive friendships. And these experiences stay with us，over and above what happens later. As technology makes it increasingly easy to make many superficial(表面的)friends, spending time and attention in developing close connections with a few people s hould be a main concern. ”28. According to the study, making good friends at high school will .A.help you believe in yourselfB.help you keep away from anxiety in lifeke away your symptoms of depressionD.make you experience more worry29. What do the numbers in paragraph 3 show about the research?A.It costs researchers a Lot of money.B. It is scientific.C.It is carried out by teenagers themselves.D. It is made in both America and Africa.30.What can we learn from the last paragraph?A. High schoolers prefer to be liked by strangers,B. Friendships have nothing to do with technology.C. True friendship calls for much energy.D. A few people can’t be a social net,31. What might be the best title for the passage?A.Friends Make a Difference to Your LifeB. Close Friendships Can Give You Strength in LifeC. Being Popular at High School Is. Really ImportantD. Good High School Friends Add to Your Happiness LaterDThere is a new kind of glasses that permits people considered legally blind (弱视）to see again. The company eSight invented them. A camera is set in the middle of the glasses, it catches video pictures of whatever is before it. The computer in the glasses immediately deals with the video and shows it on two screens in front of the user, s eyes. The video is improved by the glasses’ technology so that the user is able to see the picture.The glasses themselves also focus(聚焦)very quickly between short, middle and long distance vision(视力). This makes the user move easily from reading a book,to watching TV or to looking out of a window.Jeffrey Fenton says users of the glasses can see things almost as if their eyes were good.“The glasses are almost bombarding the eyes with so much information to send to the brain through the eyes that they can present them “with a picture that is pretty much what you would see or I would see. ”Users are advised to take time to get used to the glasses. In the beginning，they should wear them just a few hours at a time while their eyes adjust (调整）.The eSight glasses are expensive. But, user Julissa Marquez says the cost was worth it. Marquez lost most of her eyesight from an attack in 2013. After more than ten operations she was left with about 30 percent vision inone eye. Through the eSight glasses，however, she says her eyesight is “amazing”. a...1 get to see my sons. J am going to see him graduate* That is something huge for me because I love my child. He is my world. ”32. What is the first paragraph mainly about?A. What video pictures the glasses provide.B. How the electronic glasses work.C. How far a person with the glasses can see.D. What role the computer plays in the glasses.33. What does the underlined word “bombarding” in paragraph 3 mean?A.Protecting,B.Improving.C.Providing.D. Covering.34.What should users keep in mind while wearing the glasses?A. Adjust them every few hours a day.B.Wash them frequently to keep them clean.C.Don’t use than) while looking in the distance.D.Never wear them all the time at first.35. According to Julissa, we can know that .A. she thought highly of the new glassesB.she couldn't bear the sufferings of being blindC.she expected her son to have a better sightD.she lost her eyesight in her operation accident第二节(共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。
