Fill in each blank with word or phrases that best fits the context.It was an autumn morning shortly after I moved into our first house. I was looking out of the window when my father moved around 36 on the front grass land.“What are you doing out there?” I called to him. He looked up, smiling. “I’m making you a 37 .”Knowing my father well, I thought it could be just about anything. As a jobber(个体手艺人), he was always building things out of some little things, so I soon 38 his words.Until one raw day of the following March, I glanced out of the window, little piles of dirty snow still stubbornly littering the grass land. Would winter never end? Suddenly, a dot of pink amazingly came out of a drift in the yard. Was it a dream image? I 39 my coat and headed outside for a closer look.Across the muddy grass and melting snow, I stopped and 40 the grass land. They were crocuses(番红花), distributed throughout the front lawn. Blue, yellow and my favorite pink-little faces were waving in the 41 wind. I smiled, remembering the bulbs (球茎)my father had secretly planted last autumn. He knew how the dark and dull winter always got me down. How blessed I was, not only for the 42 , but for him.The crocuses bloomed each spring for the following years, bringing to me that same thought every time they arrived: Hard times are to be over. 43 and light is coming soon. However, a spring came with only half the usual blooms and none from then on. I felt down again.Many years passed by and I 44 the crocuses very much. And every time I passed the grass land, I would have a glance at it. Then, on a pale spring afternoon this year, while I was turning my 45 into my driveway, suddenly a dot of pink attracted me. Was it a crocus? I couldn’t believe it because they had not blossomed in the past ten years? But there was really one pink crocus, 46 waving in the wind. Tears filled my eyes as I realized its significance. The pink crocus bloomed for only a day, but it built my 47 for a lifetime. As a result, I no longer felt down in the following winter days.36.

A young beautiful but serious woman teacher came in. “You are not permitted to interrupt me in the course of class unless...”. She was speaking 49 I heard a voice “Lily, Lily” from outside the door. My grandmother was standing there, witha pair of socks in her hand. I didn’t realize that I was bare feet50 then. I shook my head, meaning “Don’t wait here any 51 . Leave quickly.” As I did so, I still fixed my eyes on the teacher，52 wanting her to take notice of me, 53 she did. She went out to get the socks. I was so nervous that my shaking hands couldn't get 54 onto my feet easily.Just then I heard my name called and a voice, “Can you count the numbers from one to one hundred?” the teacher said. I nodded and did very well. Finally she said, “Be seated, please. Study hard.” I Looked up at her and found55 smile on her face. I felt relaxed at last. My first day at school has stayed in my memory as something embarrassing but sweet.PART THREE READING COMPREHENSIONDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.AI was a medical student. To gather data for my paper, I started visiting patients at Dr Sardjito Hospital, where I would review the medical records of patients and then interview them.One evening, I was in a ward, desperately “hunting” for the fina l three patients I needed to complete my study. Holding a patient questionnaire, I walked towards a room. A patient called Ms A was lying in bed, clearly still weak. There were no relatives or friends with her. Even the bed beside her was empty. I sat down on a chair next to her bed, and in a low voice I introduced myself and asked if I could gather some additional information from her. She agreed. After I finished, I prepared to leave. Before I could stand up, Ms A said, “ I haven’t seen you here before, doctor. Are you new?” “Not really, Madam. It’s just that I don’t come here every day,” I replied. Ms A started talking about herself. She shared her difficulties and sufferings, talked about her husband, who was killed in a car accident, and that she struggled to earn money. All I did was nod my head as a way of showing my sympathy.Without realizing it, I had begun holding Ms A’s hand. Finally, Ms A stopped talking. “I’m very sorry for keeping you here to listen to my problem, but I feel relieved now. I had no one to pour out my problems to.” Tears fell from the corner of her eyes. Finally, I knew what to say. “It’s OK, Madam. It’s part of my duty.” I stood up and waved goodbye. A few days later, when I returned to the ward, I discovered Ms A had left the hospital as her condition had improved.Ms A taught me the most important lessons a doctor can learn. Sometimes patients do not need expensive medicine. They just need someone with the patience and willingness to lend an ear and spare a little of their time.56.

Louis have identified a gene that is required for proper development of the mouse ear, providing clues to deafness.In humans, this gene is known as FGF20. “When we inactivated(阻止活动) FGF20, we saw they were alive and healthy,” says senior author David M. Ornitz, Professor of Developmental Biology. “But then we figured out that they had absolutely no ability to hear.”The results show that disabling the gene causes a loss of outer hair cell, a special type of sensory cell in the ear responsible for amplifying(扩大) sound. While about two-thirds of the outer hair cells were missing in mice without FGF20, the number of inner hair cells, the cells responsible for transmitting the amplified signals to the brain, appeared normal.“This is the first evidence that inner and outer hair cells develop independently of one another,” says first author Sung-Ho, PhD, research associate. “This is important because most age-related deafness and heari ng loss caused by noise are due to the loss of outer hair cells.”As such, Ornitz and Huh believe that FGF20 signaling will be a required step toward the goal of regenerating outer hair cells in mammals, incapable of hearing restoration.The FGF20 gene stands for one member of a family of proteins known as fibroblast (纤维组织母细胞) growth factors. In general, members of this family are known to play important and broad roles in embryonic(胚胎的) development, tissue maintenance and wound healing.Ornitz and his colleagues found that FGF20 signaling must occur on or before day 14 of the embryo’s development to produce a normal inner ear. Even if FGF20 signaling occurred on day 15 or later, the inner ear still did not develop properly.“In mice, the cells that can bec ome outer hair cells must be exposed to the FGF20 protein at an early stage,” Ornitz says. “After embryonic day 14, it doesn’t matter if they see the protein. It’s too later for them to become outer hair cells.”66. After FGF20 was inactivated in mice, they __________.A. were not able to walk any moreB. didn’t appear abnormal immediatelyC. died without any symptoms soonD. saw an increase of outer hair cells67. According to the study, inner hair cells __________.A. are not affected by the absence of FGF20B. are responsible for regenerating soundC. will be missing if there isn’t FGF20D. have only been found in mice so far.68. The underlined word “regenerating” in Para. 5 can be replaced by“________”A. reducingB. fighting B. preventing D. reproducing69. What can we learn from the passage?A. Mammals are capable of restoring hearing themselves.B. Age-related deafness may be cured with FGF20 signaling.C. Most deafness among people is caused by the loss of inner hair cells.D. To generate outer hair cells, cells must meet the FGF20 protein on day 14.70. What is the passage mainly about?A. Why people become deaf.B. How to cure deafness.C. A new discovery about the gene PGF20.D. How the ear works.PART FOUR WRITINGSECTION ADirections: Read the following passage. Complete the diagram/Fill in the numbered blanks by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.We all know eating out can be a lot of fun. There’s th e experience of having someone wait on your every need, the social aspect of being in a restaurant with friends and, of course, the great benefit of the lack of in-home cleanup.We all also know eating out can be expensive, and I’m pretty sure college isn’t the most financially successful time in a normal person’s life. That’s why eating at home for a majority of meals really is the only option for many college students.Eating at home doesn’t have to be dull, boring, or difficult. It can and should be an e nergetic, creative experience that transforms the way you look at food. When you cook for yourself, you know exactly how your pasta（意大利面）is going to turn out. You know where the greens in your salad come from. You know the olive oil you’re using really comes from olives that are pressed for the first time. Use eating at home as an opportunity to learn and develop your kitchen skills. I promise you they will remain useful and rewarding for the rest of your life.Another important concept is to keep in mind that when it comes to shopping for food—less quantity, more quality. Buy base ingredients that are fresh, as local as possible and beautiful, and anything you cook will improve greatly. I promise you will be just as satisfied by eating a little bit less of something with a lot more quality.I am not saying eating out is a bad thing. But I insist there are many more places that are not worth your cash. Put a little more effort into cooking for yourself at home and you will gain experience and appreciation for the world of food.Title : Eating out or at home?I. Eating out: 71 but expensive★having someone wait 72★being in a restaurant 73★Freeing people from in-home cleanup.★Meeting financial problems because of 74II. Eating at home: to be creative and rewarding★Providing an experience to change your view on how you 75 — the way of the pasta turning out, the greens in salad 76 and the truth of olives being pressed for olive oil★77 skills in the kitchen★Being satisfied by eating a little less quantity with 78III. 79★80 and you will gain experience and appreciation for the food worldSECTION BDirections: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.I still remember the days when I was a youthful student in an engineering school. I lived a casual life, without caring about the future. I smoked, drank with friends and made girl friends. Little did I realize that casualness would certainly lead to loss.Two years had passed and I was staring down a report card that highlighted FALL in more than half the subjects. I didn’t care, at least not until my dad found about it. You see, I studied In India and unlike the United States where the students are expected to finance their own education, my dad financed me.Then came the day when my dad found out my habit of smoking. He lost his temper but he just told me, “Son, your allowance is cut in half from this moment on”. It hit me like a roundhouse kick.(回旋踢) from Bruce Lee. I was shocked out of my bones. I couldn’t comprehend how to pay off the debts that I had accumulated in college. I owed everybody money: the grocery store, the bars, the restaurants, my friends, etc. I was living a life filled with credit.When I went back to college, I knew that if I don’t change the way I live my life I won’t be able to pay everybody off. So I decided to make some changes. I quit smoking, cut off from my friends who led me down the wrong the road, starting hanging out in libraries and reading my engineering books.One year later, I went from a miserable failure to a magna cum laude(优等成绩). Life was never the same again. This incident made me know that anything is possible if you take action and do something about it, however small or large. Even today it still motivates me when I feel that I’m about to lose or give up. It reminds me that I can do it.81. What kind of life did the author live in the engineering school? (No more than 12 words)82. When did the author begin to care about the serious situation? (No more than 14 words)83. How did his father deal with his son’s problem? (No more than 8 words)84. What did the author learn from this incident? (No more than 12 words)SECTION CDirections: Write an English composition according to the instructions given below in Chinese.请你以“My recipe (秘方) for success”为题，写一篇120词左右的短文。

王国维在中国文论史上可谓是独树一帜。
《人间词话》集中代表了他的文论思想，其中提出了非常有影响的“境界说”。
境界说主要是在围绕文学的一种审美特质“真”而言，这里的“真”指的是真情，即真我之情。
王国维将境界定为文学的最高审美标准，他在《人间词话》中认为在文学作品中表现“真我”是有境界的重要标准之一。
而“真”这一美学概念，实际上与道家所说的“自然”有着某种内在的传承。
道家的文化思想是崇尚自然，而这个自然的本质是在强调真。
道家强调的是人的自然本性的实现，他们将人的本性看做是最本质，也是最美的东西。
在王国维看来，他所赞赏的作品都是美的，是真实的，是自然的。
在他的审美意识中，美与真实、自然有着一脉相承的关系。
王国维在《人间词话》中频繁地强调“真”的思想，对于李后主、纳兰性德的评价尤其之高。
他认为李后主是“生于深宫之内，长于妇人之手”，不谙世事，保持着一颗纯真的心，所以后主的词可以表现出真实的自我，有着超然于他人的地方，而得写词的真谛。
而纳兰性德的祖先为游牧民族，他们还有着没有被汉文化所同化的地方，保持着那种蛮荒而真实的野性和天真，这也是词人得以表现那份真我的重要原因。
这里的“真”说的就是真性情，是真实感受的流露。
王国维所言“真”强调的是“自然”，他言境界未曾离真，言真又未曾离自然，由此可知，自然乃真之内涵。
