17、for the first time. The hill out of the starting gate looked so scary that I backed off. My parents took me back for another try the next week. I fell almost immediately but still managed to win the second place. Ive loved racing ever since.I turned pro at 15, which isnt possible now. You have to be

18、 17 to compete professionally. Around the time I went pro, BMX became an Olympic sport and I decided to pursue it after high school. Im the youngest woman with a professional title in the United States.BMX isnt judged on tricks or how you handle barriers, but its an extreme sport. Its like horse rac

19、ing mixed with riding a roller coaster. It starts with a huge burst of speed I go 40 mph by the time Im two and a half seconds out of the gate. Then I try to come out in front of seven competitors at the end of the track, which includes 40-foot jumps. I keep chasing the high that comes from prestart

20、 nervousness, big jumps, and that feeling of crossing the finish line first. Strength and balance are key in competition, so I work out at least five days a week to prepare. I do tons of resistance and agility (灵活) training, both on and off the bike. I also do mental drills with a sports psychologis

21、t to make sure Im focused and confident going into competition. If I make a mistake on the course, I have to move on.

Ambitious and hard-working.D. Independent and cooperative.CA calorie deficit is a state in which you burn more calories than

25、you consume. As one of the most popular approaches to losing weight, how does it work? For example, if you burn 2,500 calories per day but only eat 2,000, you have created a deficit of 500 calories per day. There is mathematical certainty. But, this by no means tells the whole story about how calori

26、es deficit affects our lives.Before wondering what a calorie deficit is, its probably best to learn what a calorie is. A calorie is a unit that we use to track our bodys energy expenditure (消耗) and storage. In order to just stay alive, human beings (and animals) burn calories. This means, even befor

27、e we perform any activity, our bodies are already using energy (measured in calories) to keep us alive. Around 70% of the calories we consume are spent on just keeping our vital organs running. Thus, if a person consumes calories far less than needed to look thin,it may have negative effects on the

28、body. When people pick up a calorie deficit, they often merely note that the calorie math is irrefutable (无可辩驳的). The question here is that not all calories are the same. If you eat a few bags of potato chip worth of calories to support the calorie intake needed to maintain or cut down on your weigh

29、t, it will work. But, this doesnt have the same effect on your body and overall health as a balanced nutritional meal containing the same amount of calories. It seems like a simple unit of energy has become an object of our societys obsession. It neednt be that way. Remember, calorie deficits are ju

30、st a tool, which serves a purpose in losing some weight and keeping track of your calorie intake seems simple enough.28. What do we know about the calorie deficit?A. It helps people lose weight.B. It is a way of doing exercises.C. It affects peoples lives positively.D. It means the calories people c

31、onsume.29. Which of the following statements can be learned in Paragraph 2?A. A calorie is a unit to store daily energy.B. People need to burn calories to be alive.C. Calorie intake is merely to keep our organs operating.D. Living animals only burn calories after activities.30. What is suggested for

32、 people to lose weight healthily?A. Focusing on the calorie math when eating.B. Focusing on different calories when eating.C. Having bags of potato chips containing enough calories.D. Having balanced nutritional diets containing proper calories.31. What is the text mainly about?A. Influences of calo

33、rie deficits.B. Approaches to lose weight.C. Distinctions between calories.D. Ways to track calorie intake.DDelivery robots, once a sci-fi fantasy, became a reality this year. Theyre increasingly being seen as a solution to last-mile delivery delivering goods from a local warehouse to their final de

34、stination. But how do robots find the door? Its not always simple. GPS can take the robot to the right address, but cant tell it whether the door is to the left of the garage or at the end of the garden path. Thats why researchers at MIT have developed a new robot navigation (导航) system. In the new

35、system, which covers an area of three suburban neighborhoods, they trained the algorithm (算法) on satellite maps. Michael Everett, a graduate student in MIT, color-coded the maps based on environmental features sidewalks yellow, driveways blue, doors gray. He trained the program using both complete i

36、mages of the landscape and images that were partly covered, since a moving robot will often have its view partially blocked by street features, cars or pedestrians.Everett and his team then developed a cost-to-go estimator algorithm for choosing a path of maximum efficiency (and thus minimum cost).

37、This algorithm created a second map, where darker locations are farther from the goal, and lighter locations are closer. A road or sidewalk might be darker, while a driveway would be lighter and the lighter it is, the closer it gets to the front door. The front door the destination is the lightest.

38、This cost-to-go estimator map helps a robot make informed decisions on the fly. The new system proves to be both efficient and accurate. It is an important step in achieving faster real-time delivery, says Mohit Bansal, a professor at the University of North Carolina.Bansal says the next hurdle will

39、 be to enable robots to handle longer commands, including commands with negation (such as dont go to the side door). Another challenge will be developing robots that can ask questions if they get lost or confused.My vision there is that all our robots are going to be able to just understand really c

40、asual human instructions like, hey, robot, go grab a coffee for me. Everett says.32. Why do MIT researchers develop a new navigation system?A. To avoid the signal failure.B. To improve the function of GPS.C. To take robots to the right address.D. To guide robots to deliver goods precisely.33. We can

41、 infer that the purpose of using partly-covered images is to .A. instruct robots to catch colorful picturesB. enable robots to identify cars and pedestriansC. redirect robots when they are disabled by trafficD. help robots better recognize environmental features34. What is Michael Everetts attitude

42、towards the future of robots?A. Objective.B. Optimistic.C. Cautious.D. Ambiguous.35. What is the best title for the text?A. Forget About the Post Office-Robots Can HelpB. Helping Delivery Robots Find Your Front DoorC. Covering the Last Mile So Close Yet So FarD. Open Your Door to the MIT Delivery Se

43、rvice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。选项中有两项为多余选项。In everyday life, we are often faced with important decisions such as whether to apply for a new job or start a new course. 36 The more we can test our limits and abilities, the more we will learn about ourselves. New challenges are

44、 opportunities for us. 37 Rather than seeing the opportunity, often, we focus on what it will be like to fail. As a result, taking on a new challenge can be frightening. In these cases, we may avoid the challenge altogether and carry on down the same path we were on.We make some excuses to ourselves

45、 so that we can stay in our comfort zone. 38 By avoiding challenges, we dont have the opportunities to learn about ourselves. We feel trapped. We are troubled by discomfort, anxiety, and the sense that things are not quite right.There are times when we might want to avoid a challenge for good, reali

46、stic reasons. Perhaps, deep down, we are frightened of what other people might say and of what we might learn about ourselves. But instead of acknowledging that, we tell ourselves that now is not a good time, or that this isnt the right opportunity. 39 To lead an successful life, we need to take on

47、new challenges that give us more opportunities to be ourselves. It is not that successful people dont feel the same fear; rather, they are simply more willing to face their fear. 40 The question is not how to lead a life in which we never feel the fear of failure, but rather, how we can moved forwar

48、d despite our fear.A. In reality, it is our fear talking.B. The fear of failure can be too much to bear.C. However, we dont always see it that way.D. People think we can stay in our comfort zone and keep learning.E. Taking on such challenges is an important part of growing as a person.F. But the tru

49、th is that staying in our comfort zone is not necessarily comfortable.G. They are open to new experiences, cherishing the challenges of learning about themselves.第三部分 语言知识运用(共两节,满分45分)第一节 (共20小题;每小题1. 5分,满分30分)阅读下面短文,从短文后各题所给的 A、B、C 和 D 四个选项中,选出可以填入空白处的最佳选项。It was10:15 p.m. when Esposito arrived at

73、了现实。他们越来越被视为“最后一英里送货”的解决方案将货物从当地仓库运送到最终目的地。但是机器人如何找到门呢?这并不总是简单的。GPS 可以把机器人带到正确的地址,但不能告诉它门是在车库的左边还是在花园小路的尽头。这就是为什么麻省理工学院的研究人员开发了一种新的机器人导航系统。在这个新的系统中,他们在卫星地图上训练了这个算法。迈克尔埃弗雷特,麻省理工学院的一名研究生,根据环境特征对地图进行了颜色编码,人行道是黄色的,车道是蓝色的,门是灰色的。他用完整的风景图片和部分被覆盖的图片来训练这个程序,因为移动机器人的视野经常会被街道、汽车或行人部分挡住。埃弗雷特和他的团队随后开发了一种“成本估算”算法

74、,用于选择效率最高的路径(从而使“成本”最低)。该算法创建了第二张地图,其中较暗的位置离目标较远,较亮的位置离目标较近。道路或人行道可能较暗,而车道颜色可能较亮。车道越靠近前门颜色就越亮,目的地前门,颜色最亮。这个成本估算图可以帮助机器人在飞行中做出明智的决定。北卡罗来纳大学教授莫希特班萨尔说:“这是实现更快实时传输的重要一步。”。班萨尔说,下一个障碍将是使机器人能够处理更长的命令,包括带有否定的命令(例如“不要走到侧门”)。另一个挑战将是开发可以提出问题的机器人,如果他们迷路或困惑的话。埃弗雷特说:“我的设想是,我们所有的机器人都将能够理解非常随意的人类指令,比如,嘿,机器人,去给我拿杯咖啡

75、。”。七选五:【答案】36-40 : E C F A G 文章大意:鼓励人们走出舒适区,接受挑战,面对恐惧。36. 结合下文,说的是挑战可以使人突破极限获得成长,可见本句是在鼓励接受挑战。故选E。37. 结合下文的 rather than,说的是人们只会看到失败的可能性,可见本句要提到人们不会看到挑战的好处。故选C。38. 结合上下文,前文在说人们往往找寻借口待在自己的舒适区,后文在说待在舒适区的种种坏处,可见本句在说舒适区不是件好事情。故选F。39. 结合前文的 frightened,说的是人们有时候其实是出于害怕而不做某事,却要找借口说这不是合适的时机,可见本句要反驳这个借口,表明实际是因
