When I contacted famous researchers to suggest cooperating，as is typically required for high­profile projects，they frequently replied enthusiastically to start，agreeing my project sounded interesting and promising.But when they learned I had just established my lab，they became skeptical and hesitant，ultimately saying no.And when I sought grant funding，my lack of experience and reputation was cited as a reason to deny support for my ambitious proposals. I spent about two years being stuck in this mindset，excited about my big ideas but making little actual progress，leading to frustration and depression.As I neared my breaking point，I began to ask myself：Were big projects really the only route? When I shifted to small projects，I became brave enough to step into fields I was not familiar with.By reading papers in new areas，I found creative ideas to pursue.When I discussed these adventurous，low­cost projects with early­career researchers，they were glad to cooperate.We secured funding.When I published papers out of these projects，they were not exciting enough to make headlines—but for me，it was a moment of joy and self­contentment. It has now been 3 years since I embraced this “small” approach.Sometimes senior colleagues say I'm wasting time with projects that aren't important enough.But I disagree.When I do these studies，I also find clues for future big projects.Going forward，I will still commit part of my time to exploring small projects，which I think can help pursue more fundamental questions. 4．What is the author trying to do with big projects? A．Pursue his graduate studies. B．Seek a route to academic success. C．Apply for an associate professorship. D．Establish an academic research center. 5．What prevented the author pursuing his big project? A．Lack of necessary support. B．The toughness of work. C．Shortage of academic talents. D．The opposition from colleagues. 6．How did the author carry out his small project? A．By publishing influential papers. B．By getting young colleagues' funding. C．By exploring and initiating new ideas. D．By cooperating with senior colleagues. 7．What does the author learn from his experience? A．Good jobs require a high degree. B．Ambition isn't fit for the young. C．Success results from preparation. D．Small doesn't mean unimportant. 【语篇解读】本文是一篇记叙文。文章讲述了作者本想以大项目作为寻求学术成功的途径，但是由于缺乏经验和声誉没能成功。 后来作者转向小项目，找到了可以追求的创造性想法，逐步走向成功。 由此作者感悟到小项目不代表不重要，反而更有助于解决更基本的问题。 4．B　[解析]细节理解题。根据第一段中的“This was the only way to lay a foundation for a successful academic research career.”可知，作者想以大项目作为寻求学术成功的途径。故选B。 5．A　[解析]细节理解题。根据第二段中的“But when they learned I had just established my lab ... deny support for my ambitious proposals.”可知，缺乏必要的支持阻止了作者追求他的大项目。故选A。 6．C　[解析]细节理解题。根据倒数第二段中的“When I shifted to small projects，I became brave enough to step into fields I was not familiar with.By reading papers in new areas，I found creative ideas to pursue.”可知，作者通过探索和提出新的想法来进行他的小项目。故选C。 7．D　[解析]推理判断题。根据最后一段中的“Going forward，I will still commit part of my time to exploring small projects，which I think can help pursue more fundamental questions.”可知，作者从他的经历中学到小不代表不重要。故选D。 Ⅱ.完形填空 One day，a young man，Cesar Larios，visited a tall building to move something for his boss.The building is too tall，so taking the lift is quite __1__． __2__，the lift stopped working.The young man was __3__ inside the lift.Inside the lift，Rita Jung，an elderly __4__，got into the same trouble as him.She knew it would be difficult for her since she could not stand for a long time and immediately __5__ out her worry.Rita __6__ she would feel very uncomfortable or even a(n) __7__ in her knees if she stood there too long.

Culture begins with the “honeymoon stage”．This is the period of time when we first arrive in a country where everything about the new culture is strange and exciting.We may be suffering from “jet lag” but we are thrilled to be in the new environment，seeing new sights，hearing new sounds and language，eating new kinds of food. Unfortunately，the second stage can be more difficult.After we have settled down into our new life，we can become very tired and begin to miss our homeland and our family，friends，and pets.All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture. The third stage comes when you begin to realize that things are not so bad in the host culture.Your sense of humor usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place.Things are still difficult，but you are now a survivor. The fourth stage can be called “at ease at last”．Now you feel quite comfortable in your new surroundings.You can cope with most problems that occur.You may still have problems with the language，but you know you are strong enough to deal with them. There is a fifth stage of culture shock which many people don't know about.This is called “reverse culture shock”．Surprisingly，this occurs when you go back to your native culture and find that you have changed and that things there have changed while you have been away.Now you feel a little uncomfortable back home.Life is a struggle! 1．When does culture shock happen? A．When you reach your teens. B．When you begin an urban life. C．When you go to live in a foreign culture. D．When you meet foreign people for the first time. 2．How do you feel during the first stage of culture shock? A．Happy and excited. B．Bored and homesick. C．Lonely and depressed. D．Angry and frustrated. 3．How could the third stage be described? A．Adjustment. B．Rejection. C．Enthusiasm. D．Embarrassment. 4．Why might reverse culture shock be a problem? A．It hardly ever happens. B．It is extremely stressful. C．It is out of expectation. D．It only happens to young people. 【语篇解读】本文是一篇说明文。心理学家告诉我们，当我们进入并生活在一种新的文化环境时，会经历文化冲击的四个基本阶段，在返回本土文化环境后还可能会遭受逆向文化冲击。 1．C　[解析]细节理解题。根据第一段内容、第二段中的“Culture begins with the ‘honeymoon stage’．This is the period of time when we first arrive in a country where everything about the new culture is strange and exciting.”及最后一段中的“There is a fifth stage of culture shock which many people don't know about.”可知，当人们进入一个新的文化环境时，即开始生活在外国文化中，会发生文化冲击，故选C。 2．A　[解析]细节理解题。根据第二段中的“Culture begins with the ‘honeymoon stage’．This is the period of time when we first arrive in a country where everything about the new culture is strange and exciting.” 以及we are thrilled to be in the new environment可知，在文化冲击的第一阶段，你会感到快乐和兴奋，故选A。 3．A　[解析]推理判断题。根据第四段中的“The third stage comes ...Your sense of humor usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place.”可知，在文化冲击的第三阶段你通过学习如何在新环境中照顾好自己，变得越来越强大。由此推知，你在调整自己适应环境，故文化冲击的第三阶段被称为“调整阶段”，故选A。 4．C　[解析]细节理解题。根据最后一段中的“There is a fifth stage of culture shock which many people don't know about.”可知，逆向文化冲击可能成为一个问题，这是因为人们对逆向文化冲击不了解，所发生的一切出乎人们的意料，故选C。 B One of the improv(即兴表演) classes I attended regularly was taught by Jim Cranna every Saturday afternoon.Sometimes，as many as twenty­five to sixty­plus folks showed up.Jim made sure to fit everyone in so they could improve their skills.The class lasted for three hours.The usual cast of comic actors played improv comedy games.And we would go to the nearest mini market located in the building and get a snack or coffee during breaks. One day，three of us were standing outside the building，when Robin Williams—an internationally famous actor and comic walked by，enjoying the fresh bay air.Completely frozen，my fellow comics couldn't summon up the courage to just say “hi” to Robin，who was with a friend.I froze for a moment，but then I composed myself. I told them，“Hey，if you guys can't handle it，then I will ask him to come and join us for the second half of class.” I could hear them mumble under their breath，“Yeah，sure，right.You're going to ask Robin Williams to come to our comedy class.Good luck with that one！” So I went up to Robin and his friend and asked him to join us.“We're having an improv comedy class.We're on break now，but we would be most humbled and honored if you would join us for the second half of the class.”Robin looked directly in my eyes and said with little hesitation，“Okay.” It was like a grown­up child being asked to come and play.With that，he and his friend followed me up to the class. When he saw Robin，Jim said，“Oh my goodness，look who Micheline is bringing to class.”Jim's eyes were all in astonishment and delight.“Why，it's Robin Williams！” Robin and his friend stayed the rest of the class and at the end of the class，Robin and Jim performed a skit(滑稽短剧).We actually watched him shape­shift as he prepared physically and mentally for his made­up character.He gave it his all.It was truly magical. What a delight for all of us that Saturday afternoon! All I know is that if I hadn't mustered up the courage to ask Robin to join us，none of us would have had that experience. 5．What does the underlined word “composed” mean in Paragraph 2?
