第二部分阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A 、B 、C 和D ）中，选出最佳选项。
A
I told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, ―You mean fortunately.‖ He explained that I should be glad of the extra exercise that the hill provided.
My attitude to the hill has now changed. I used to grumble as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smile of satisfaction as I reach the top of the hill.
Problems are there to be faced and overcome. We cannot achieve anything with an easy life. Helen Keller was the first deaf and blind person to gain a university degree. Her activism and writing proved inspirational. She wrote, ―Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved.‖One of the main determinants of success in life is our attitude towards adversity (逆境). From time to time we all face hardships, problems, accidents, afflictions and difficulties. Some are of our making but many confront us through no fault of our own. While we cannot choose the adversity we can choose our attitude towards it.
Douglas Bader was 21 when in 1931 he had both legs cut off following a flying accident．He was determined to fly again and went on to become one of the leading flying aviators in the Battle of Britain with 22 aerial victories over the Germans．He was an inspiration to others during the war. He said, ―Don‘t listen to anyone who tells you that you can‘t do this or that. That‘s nonsense. Make up your mind, you‘ll never use crutches (拐杖) or a stick, then have a go at everything. Go to school, and join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or
impossible.‖
The biographies (传记) of great people are full of examples of how they took steps to overcome the difficulties they faced. The common thread is that they did not become depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.
Nevertheless, there is still the problem of how you change your attitude towards adversity.
21. Which of the following is true according to the author of the passage?
A. People are silly to pay to go to the gym.
B. Climbing hills on bicycles is the best way to take exercise.
C. Those who want to achieve success can‘t expect to live an easy life.
D. People‘s attitude towards adversity is the only factor that determines whether they will succeed.
22. By quoting what D ouglas Bader said, the author intends to tell us ―.‖
A. Failure is the mother of success．
B. A fall into the pit, a gain in your wit.
C. If you venture (冒险) nothing, you will have nothing.
D. Nothing is difficult to the man who will try.
23. Following this passage, the author will further talk about .
A. how his friend helped him to change his attitude towards the adversity he faced
B. what steps to take to change your attitude towards the adversity you face
C. why it is important to keep optimistic in face of adversity
D. what great people have in common
24. Which of the following can best function as the title of the passage?
A. Face adversity with a smile
B. Different attitudes towards adversity
C. Nothing is impossible
D. Life is full of adversity
B
Audrey Hepburn won an Academy Award as Best Actress for her first major American movie, Roman Holiday, which was released in 1953. But she is remembered as much for her aid work as for her acting.
Born in Belgi um in 1929, Audrey‘s father was British and her mother was Dutch.
Audrey was sent to live at a British school for part of her childhood. During World WarⅡ, she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks. Audrey studied dance as a teenager and during college when she returned to London after the war. But she realized she wasn‘t going to be a ballerina. So s he began taking acting parts in stage shows. Later she began to get small parts in movies.
But it was Audrey Hepburn‘s move to America that brought her true fame. In 1951 she played the character ―Gigi‖ in the Broadway play of the same name to great cr itical praise. Two years later, Roman Holiday made her a star at the age of 24.
Audrey made more than 25 movies. Among her most popular roles was Holly Golightly in Breakfast at Tiffany‘s in 1961. Three years later she played Eliza Doolittle in My Fai r Lady.
She got married two times and had one son by each husband. In 1989, the UN Children‘s Fund named Audrey a goodwill ambassador. She travelled all over the world in support of UNICEF projects. The UN agency said she was a tireless worker. She often gave 15 interviews a day to gain money and support for UNICEF projects.
Audrey Hepburn often said her loyalty to UNICEF was the result of her experiences as a child during World WarⅡ. She said she knew what it was like to be starving and to be saved by international aid. She was a goodwill ambassador until her death in 1993 from colon cancer.

Call it what you will—coincidence, fortune, luck or even fate—sometimes events combine together to show us that this is indeed a very small world. We‘ve probably all had at least one experience where we‘ve said ―What a coincidence!‖ because there‘s no logical explanation for what has happened. Take the following stories from writer Lorri Benedik as examples:
My friend, Emma Daniels, spent the summer of 1974 travelling in Israel. During her a month–long stay in Jerusalem she frequented a café called Chocolate Soup. It was run by two men, one of whom, Alex, was a former Montrealer (蒙特利尔人). One morning when Emma went in for coffee, while chatting with her new friend Alex, she mentioned that she had just finished the book she was reading and had nothing else to read. Alex said he had a fabulous (寓言的) book she might like, and that he‘d be happy to lend it to her. As he lived just above the café, he quickly ran up to get it. The book he handed to Emma just minutes later was Markings，a book of spiritual writings by former Secretary–General of the United Nations Dag Hammarskjld.
Emma had never read it, nor had she ever purchased a copy. But when she opened it up, she was floored to see her own name and address inside the cover, in her own handwriting. It turned out that the summer before, at a concert back in Montreal, Emma had met a Californian who was in town visiting friends. They decided to exchange addresses, but neither of them had any paper. The man had opened up a book he was carrying in his backpack and asked Emma to write her name and address inside. When he returned to California, he left the book behind in Montreal, and his friend Alex kept it. When Alex later relocated to Jerusalem, he took the treasured book along.
Then there was the time that my husband voluntarily answered the phone at my parents‘ house, something he has never done in more than a dozen years of visiting them almost every weekend. But this time he got up from the dinner table, without being asked, when the phone rang. He was gone for quite a while and was quite pale when he returned to the dining room. It was a wrong number, he told us, but he had recognized the voice. It was his estranged(疏远的) sister, with whom he hadn‘t spoken in years.
29. What does the underlined word ―floored‖ in the third paragraph mean?
A. interested.
B. shocked.
C. frightened.
D. excited.
30. From the last paragraph we can draw a conclusion that .
A. Lorri Benedik‘s husband often paid visits to her parents‘ house at weekends
B. Lorri Benedik‘s husband knew it was his sister‘s phone when he went to answer it
C. Lorri Benedik persuaded her husband to answer the phone of her estranged sister
D. His estranged sister made the phone call to Lord Benedik‘s husband on purpose
31. Which of the following statements is TRUE according to the passage?
A. Emma Daniels stayed in Israel in 1974 for half a year.
B. Emma Daniels once stayed in Montreal for some time.
C. The book ―Markings‖ was completed by Lord Benedik in a very short time.
D. Emma Daniels and the Californian kept in touch with each other by writing letters.
D
Cole Bettles had been rejected by a number of universities when he received an e-mail from the University of California, San Diego, last month, congratulating him on his admission and inviting him to tour the campus. His mother booked a hotel in San Diego, and the 18-year-old Ojai high school senior arranged for his grandfather, uncle and other family members to meet them at the campus for lunch during
the Saturday tour.
―They were like ?Oh my God, that‘s so awesome (棒的)‘‖ Bettles said. Right before he got in bed, he checked his e-mail one last time and found another message saying the school had made a mistake and his application had been denied.
In fact, all 28, 000 students who turned away from UC San Diego, in one of the toughest college entrance seasons on record, had r eceived the same incorrect message. The students‘ hopes had been raised and then dashed (破灭) in a cruel twist that shows the danger of instant communications in the Internet age.
UCSD admissions director Mae Brown called it an ―administrative error‖ but refused to say who had made the mistake, or if those responsible would be disciplined (受训).
The e-mail, which began, ―We‘re thrilled that you‘ve been admitted to UC San Diego, and we‘re showcasing (展示) our beautiful campus on Admit Day, ‖ was sent to the full 46, 000 students who had applied, instead of just the 18, 000 who got in, Brown said.
The error was discovered almost immediately by her staff, who sent an apology within hours.
―It was really thrilling for a few hours; now he‘s crushed (压垮),‖ said Cole‘s mother, Tracy Bettles. ―It‘s really tough on them.‖
The admissions director said she was in the office on Monday until midnight answering e-mails and phone calls from disappointed students and their parents. She said she took full responsibility for the error. ―We accessed the wrong database. We recognize the incredible pain receiving this f alse encouragement caused. It was not our intent.‖
32. How many students received an admission e-mail from the University of California, San Diego
(UCSD)？
A. 18, 000
B. 28, 000
C. 46, 000
D. 18
33. Which of the following statements is TRUE about the wrong e-mail message?
A. The mistake was made on purpose to cause pain among the applicants.
B. It was UCSD admissions director Mae Brown who made the mistake.
C. UCSD admissions staff got information from the wrong database.
D. Staff did not discover the mistake until next Monday.
34. The admissions director Mae Brown did what she could to __________.
A. make up for the mistake
B. punish herself for the mistake
C. protect the person who made the mistake
D. help the disappointed students enter the university
35. What does the passage mainly talk about?
A. Cole Bettles was admitted to the UCSD.
B. Cole Bettles was rejected y a famous university.
C. USCD admissions office often makes ―administration errors‖.
D. False admission information raised the students‘ hopes and then dashed them.

Recently some American scientists have given a useful piece of advice to people in
industrialized nations. They say people should eat more of the same kind of food eaten by
humans living more than 10,000 years ago. 36
The scientists say that the human life has changed greatly. Our bodies have not been able
to deal with these changes in lifestyle and this had led to new kinds of sicknesses. 37
So they are called ―diseases of civilization‖. Many cancers and diseases of the blood system are examples of such diseases.
Scientists note that people in both the Old Stone Age and the New Stone Age enjoyed
very little alcohol or tobacco, probably none. 38 However, a change in food is one of the
main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat, which had much less fat than
domestic ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or
any other dairy products, and they made very little use of grains. 39 We eat six times
more salt than our ancestors. We eat more sugar. We eat twice as much fat but only one third as
much protein and much less vitamin C.
40 But scientists say that we would be much healthier if we eat much the same
way the ancient people did, cutting the amount of fatty, salty and sweet food.
A. Stone Age people lived a simple life.
B. But today, we enjoy eating a lot of these.
C. In that case, they would live much healthier.
D. Ancient people also got lots of physical exercise.
E. These new sicknesses were not known in ancient times.
F. People today probably don‘t want to live like our ancestors.
G. Modern people used to suffer from ―diseases of civilization‖.

45 , he began to wash his son‘s windscreen. I could f eel he was a caring man through the glass.
I learned another lesson about love a few years later. My father often 46 me early in the morning. ―Buy Xerox. It‘s a good sharp price,‖ he might say when I answered the phone. No pleasant 47 or inquiry about my life, just financial instructions. This manner of his 48 me and we often quarreled. But one day, I thought about my father‘s success in business and realized that his concern for my financial security lay behind his 49 morning calls. The next time he called and told me to buy a stock, I 50 him.
When my social style has conflicted with that of my friends, I‘ve often felt 51 . For example, I always return phone calls 52 and regularly contact with my friends. I expect the same from them. I had one friend who rarely called, answering my messages with short e-mails. I rushed to the 53 : She wasn‘t a good friend! My anger 54 as the holidays approached. But then she came to a gathering I 55 and handed me a beautiful dress I had fallen in love with when we did some window-shopping the previous month. I was 56 at her thoughtfulness, and regretful for how I‘d considered her to be 57 . Clearly I needed to change my expectations of friends.
Far too often, I ignored their 58 expressions, eagerly expecting them to do things in my 59 . Over the years, however, I‘ve learned to 60 other persons‘ love signs.
