On my fourth day in a self-driving car, I finally felt comfortable enough to let it stop itself. Before then, Id allowed the car- a Volvo S90 sedan to control the direction, with my hands still on the wheel, and to adjust speed in traffic. By Day 4, I was ready to make a jump into the future. With the car traveling on a busy road, I activated the driverless mode. Soon, a traffic light turned red. For a split second, I prepared to get on the brakes. There was no need. The cameras and computers in the Volvo recognized the traffic conditions and smoothly began applying the brake. If you're anything like most people, you're familiar with this anxiety. Almost 80 percent of Americans fear traveling in a self-driving car, a recent survey found. Researchers at the University of Chicago have conducted some clever experiments studying the phenomenon. They asked participants to complete tasks and compared their performance with a computer system's. After the computer made a mistake, people were unwilling to use it again. After the people made mistakes, their self-confidence wouldn't change. It didn't matter that the human beings made more mistakes than the computer. So it is with driving. More than 37,000 Americans died in crashes last year, most from human error. The death count from cars goes beyond that from guns. So if you are shocked and angry by guns and want things to change, you should feel the same about car crashes. Technology creates an opportunity to save lives. Computers don't get drunk or distracted by text messages, and they don't have blind spots. Just look at commercial airlines: Automation has helped all but get rid of deadly crashes among American air carriers. The last one happened in 2009. The technology for self-driving cars still isn't good enough. But it is improving rapidly. Within a few years, many cars will have advanced crash-avoidance systems and driving will be revolutionized sooner than many people now understand. 1.How does the author introduce the topic? A.By offering a piece of news. B.By describing an experience. C.By giving background information. D.By introducing a latest car. 2.What can we know from the fourth paragraph? A.The participants lost self-confidence after making mistakes. B.The participants would ignore the mistakes made by the computer. C.Car crashes is no less shocking than gun incidents. D.The death count from cars is the same as that from guns. 3.The author mentioned commercial airlines___________. A.to advertise for the commercial airlines. B.to assess the security of driverless cars. C.to find fault with computers. D.to prove the advantage of technology. 4.What's the author's attitude towards self-driving cars? A.Favorable.

Tyler and I stopped by our corner store. A few police cars caught Tyler's attention. ''Mom, can I use my allowance money and buy the policemen some doughnuts to say 'thank you'? '' he asked. ''Certainly! '' I said, feeling proud that I was achieving my aim to raise my children to be grateful, tender-hearted and caring. After we left the store, Tyler asked a question that would change our lives and the lives of countless others forever. ''Why were the police so happy about the doughnuts? '' I explained some people are not always friendly to police officers. Tyler was very sad to hear this, and instead of shrugging it off, he said that he was going to thank every cop in America and buy them each a doughnut! I was shocked, but it never occurred to me to say ''no''. In fact, I thought it was an excellent but unachievable idea. I suggested many other options, but nothing was enough for him on the new found mission (使命) I didn't know how to put this passion into action, but I knew one thing: Tyler had found his purpose, and it was my duty to help him. I e-mailed our local police office and asked if Tyler could host a thank-you event for them. They were delighted. At the event, they called Tyler ''The Donut Boy'', a name that has become known throughout the nation. Then we kept planning thank- you events and many caring people joined. We were invited to TV stations, and flew to Washington, D.C. for National Police Week. It has been three years since a simple act of kindness sparked a wonderful idea in an eight-year-old boy. In forty-eight states, more than 90,000 doughnuts have been delivered so far, with no end in sight. We've made memories that will last a lifetime, but most importantly, we have served those who serve us daily and made our mark on this world. 1.What quality of Tyler made the author feel proud? A.Independence. B.Honesty. C.Kindness. D.Cautiousness. 2.How did the author react to Tyler's wish to thank all the police at first? A.She praised him for his ambition. B.She told him it was impossible. C.She expressed her doubt about it. D.She tried to change his idea. 3.Which of the following is true according to the text? A.Tyler got the idea of buying the policemen doughnuts from the author. B.The policemen were confused about Tyler's behavior. C.Tyler has achieved his mission. D.More people joined Tyler in doing Thank-you events. 4.What is the author trying to tell us? A.A grateful heart can make a difference. B.Curiosity is the key to children growth. C.It's never too old to learn. D.It's better to be famous at an early age.

He was extremely worried as the suitcase had all his important papers, including his passport. He reported the case to the police and then sat there, lost and lonely in a strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 Every night after dinner, my grandparents would turn on TV for the 6 o'clock news. No matter how hard I tried to act the grown-up and watch with them, I would inevitably(不可避免地) get distracted until 6:30 when Wheel of Fortune came on. My grandma would play along, trying to guess the answers before the players. Her shouts of excitement when she succeeded could be heard across the house. As I grew older, my love of reading and writing blossomed, and I would join my grandma in yelling out letters. Soon, I was experiencing the thrill of solving the puzzles faster than the contestants(选手) and even my grandma. I was hooked. Due to constant moving around with my mom and father, I started to spend less time with my grandparents, but our bond remained strong. My grandparents provided me with the stability, love and support that I desperately needed when I grew up. When I was in a bad mood, I would remember those sweet nights. A few years later, I was living with my grandpa in Chicago. While watching an episode(集) of Wheel of Fortune, we had a wave of nostalgia(怀旧). With application, I didn't think much of it until I received a mail months later, announcing that the Wheel of Fortune casting team would come to Chicago. In order to be considered for an in-person audition(试演), applicants would need to submit a sixty-second video explaining why they wanted to be a contestant. All my childhood memories of watching the show came flooding back, and I knew I was meant to spin(旋转) the wheel for real. Immediately, I recorded a video and submitted it. A couple of weeks later, I received an e-mail inviting me to audition in person. I was very nervous on the audition day. I couldn't believe I was trying out for ''America's Game''! After two rounds of intense auditioning, with half of the hopefuls letting go after the first round, it was over. All of us applicants were told we would receive a letter in the mail within two weeks if we were selected. 注意： 所续写短文的词数应为 150 左右; 2. 至少使用 5 个短文中标有下划线的关键词语; 3. 续写部分分为两段，每段的开头语已为你写好; 4. 续写完成后，请用下划线标出你所使用的关键词语 Paragraph 1: I ran to the mailbox every day but there was nothing. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph 2： Then one morning while getting ready for work, I checked my mail and let out the loudest scream ever. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

It is amusing that yogurt, which was invented to make milk last longer before the days of refrigeration, now makes grocery shopping last longer. Full-fat, or nonfat? Greek, or regular? 1. A key recommendation when it comes to fat is to choose low-fat or fat-free yogurt. That's because dairy fat is mostly saturated (饱和的), the type linked with increased risk of heart disease. Besides, full-fat dairy has more calories than nonfat. This view, however, has been challenged by a few recent studies. Researchers think that full-fat dairy might offer some as-yet-unknown health benefits. It might also help with weight management because the fat in it makes it more satisfying, helping keep our appetite in check. 2. Until there are further findings, it might be wiser to choose low-fat or fat-free yogurt and add healthy fat by topping it with nuts. 3. Many of them also have a hard time deciding whether to buy Greek yogurt or regular yogurt. Greek yogurt, which was rare about a decade ago, dominates the store shelves with dozens of flavors today. It has become popular partly because it features a thick, creamy texture (口感) and contains more protein and less sugar than regular yogurt. Greek yogurt has these qualities because of its unique liquid-removing process. Unfortunately, lots of nutrients, including calcium (钙), are sometimes drained, too. Therefore, thickened yogurt and regular yogurt offer different nutritional benefits. 4. Finally, it is worth mentioning that it's the added sugar, not the naturally- occurring sugar (which is removed in Greek yogurt), that should be the cause of our concern. Fruit-flavored yogurts that appear to be healthy may have little actual fruit and plenty of added sugar instead. 5. A.Consumers, however. are not confused only about fat. B.Mixing them up and enjoying both might be a good idea. C.With so many conflicting headlines about fat these days, it's no wonder people are confused when buying dairy products. D.Our best bet might be to buy plain yogurt and sweeten it ourselves using fresh fruit. E.There are so many choices that we often find it hard to decide which yogurt to buy. F.They're naturally ''packaged'' with so many important nutrients that it would be misguided to avoid them. G.Yet more research needs to be done for us to fully understand dairy fat’s health impact .
