A
“We’re going,” Mimi called out to her mother in the family’s grocery store next to her house. This was her first date, and Robert Rovere had just arrived to take her to a dance. She could hardly believe it was happening. During the long wait she had wondered again and again what to wear, finally putting on her favourite blouse. Now at last Robert was here. He looked beautiful to her. His hair was neatly combed and he wore a yellow sweater she hadn’t seen before. Mimi felt wonderful.
As they stepped out of the door, Mimi’s mother popped out of the store and said hello to Robert. Then she put a package wrapped in white paper into Mimi’s hand.
“Limbur ger cheese for Sally Thompson, Mimi. We got a case of imported Limburger in today.
I promised Sally you’d deliver it tonight.”
“Tonight!” Mimi echoed, staring down at the cheese. “Why not tomorrow?”
“Sorry, but I promised Sally,” her mother said , “Well, have fun, you two.”
“Oh well, Robert, let’s go,” she said.
Her first date ever, her first date with Robert Rovere, and she was stuck with a large, smelly, messy package of cheese! She tried to forget it. “Here I am,” she said to herself, “going to a dance w ith Robert Rovere.” She glanced up at him.
“That cheese smells,” he said.
She held the cheese in the hand farthest from him, but the smell seemed to be crawling up her arm.
They turned onto Montcalm Street. Mimi didn’t know the house number, but she though t she’d recognize the house because she’d passed there once before. “Oh, here it is.” She rang the bell but nobody answered. Then she noticed that the name under the bell wasn’t Thompson. She had come to the wrong house. Oh, how embarrassing, she thought. She dropped the cheese into her coat pocket and rejoined Robert.
“Wrong house,” she said. “I was sure she lived there.”
“What do we do now?” Robert asked.
Mimi bit her lip. She couldn’t bring the cheese home again now. It would just have to go to the dance with her. “Let’s go,” she said. She was so miserable she couldn’t think of anything else to say, and she and Robert walked the rest of the way in a silence as thick as the bad smell of the cheese.
When they arrived at the dance, the place was full of people and there was no room to hang their coats. Mimi wanted to wash her hands, but Robert led her straight onto the dance floor. Mimi noticed that Robert smelled sweet, like lily of the valley. She smelled of Limburger cheese.
Mimi danced with all her heart. Robert’s eyes were close d，probably trying to forget her and her smell, she thought.
...
56. What particular point suggests that Mimi was nervous about her date?
A. She could hardly believe she had taken such a long time to get ready.
B. She kept Robert waiting for a long time until she was ready.
C. She spent a long time making herself look nicer.
D. She wondered many times whether Robert would like the yellow sweater.
57. What happened when Mimi brought the cheese to the house?
A. At first Mimi didn’t realize that it was someone else’s house.
B. It was not the right house but the house number was correct.
C. The wrong person came to the door.
D. There was no one at the Thompson’s home.
58. Why did Mimi bring the cheese with her into the dance hall?
A. Robert said nothing about the cheese on the way to the dance.
B. She couldn’t find any place to leave it.
C. She thought the cheese was not as smelly as the lily of the valley.
D. The room for hanging coats was full of people.
59. Which of the following was most likely to happen in the end?
A. Their first date was a success.
B. The smell ruined the date.
C. Robert took all the cheese after the dance.
D. They quarreled over the smelly cheese.

MALAYSIA'S Prime Minister, Mahathir Mohamad, retired on October 31. But he didn't go quietly. In his final speech, he blamed the Jewish people for the problems between Israel and the Palestinians.
"The Jews have taken land of the Muslims," he said. "What if part of America was given to the Jews as Israel? Would the Americans let it happen? Of course not."
His words angered many western governments, but Mahathir doesn't care. "I like to speak my mind," the 77-year-old explained. "Sometimes people don't like it. But that is what leadership is all about."
Loved by some and disliked by others, his 22 years in power have seen great changes in Malaysia. He has taken it from being one of Asia's poorest countries to the world's 18th largest trading nation. It is also a peaceful country with native Malaysians living alongside minority groups. Chinese make up a quarter of the population, while a further 7.4 percent are of Inidan origin. Teenage girls wearing Muslim headscarves happily walk around large stores as ethnic Chinese play mah-jong (麻将) in nearby cafes.
But Mahathir has made enemies at home and abroad and some people will be glad he has gone. The US was unhappy when he often blamed it for globalization. Meanwhile, critics say that he has limited the freedom of the Malaysian people in order to stay in control of the country. Despite this, he is a hero to leaders in Southeast Asia as well as those in the Islamic (伊斯兰) world. "He marked out the path to success for developing nations in the region to follow," said Thai President Thaksin Shinawatra.
Now he just wants to enjoy his retirement and insists that he will not take on a special role in government. "I'm a nobody," he said. But many Malaysians do not agree with this.
60. What does Mahathir probably mean by “But that is what leadership is all about.”?
A. The Jews have taken land of the Muslines by strong power of their leadership.
B. America should give part of its land to Israel though its leadership is powerful.
C. Leadership has the obligation to speak up what you think is right or wrong.
D. As a leader of a country, you have the right to teach those in other countries what to do
and how.
61. Which is NOT true about the following?
A. Malaysia was no longer poor after Mahathia came into power.
B. Malaysia is a country with natives and other minorities like Jews living alongside
peacefully.
C. Malaysia developed a lot within Mahathia’s powe r but freedom of Malaysians was
limited.
D. Mahathia’s role in the world is both a hero to leaders in Southeast Asia but also a possible
enemy of some countries.
62. The best title of this passage would be __________ .
A. A Religion Enthusiast
B. Mahathia’s Political Policy
C. Mahathia Is Malaysia
D. Hero of the World

Many people believe the glare from snow causes snowblindness. Yet, dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of “snow light”.
The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. A man’s eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain(地域). So his long look continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and eyeballs become sore and the eye muscles ache. Nature offers this discomfort by producing more and more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision became not clear, then is not easily seen and the result is total, even though not very long, snowblindness.
Experiments led the Army to a simple method of solving this problem. Scouts, ahead of a main body of troops, are trained to shake snow from evergreen bushes creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their eyes focus on a bush and have something to see. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is solved.
63. The first paragraph is mainly concerned with ____.
A. need for dark glasses
B. the whiteness from snow
C. headaches, watering eyes and snowblindness
D. snow glare and snowblindness
64. According to the author, recent work on snowblindness shows that it is caused by ________.
A. exposure to bright light
B. failure to focus on an object
C. a loss of vision which doesn’t last long
D. focusing on dark colored objects for a very long time
65. Suppose you walk across a completely snow-covered area, what should you do to solve the
problem of snowblindness?
A. By wearing dark sun glasses.
B. By throwing an extra pair of black shoes ahead.
C. By asking the Army for help.
D. By walking backwards.
66. A suitable title for this passage would be ____.
A. Snowblindness and How to Avoid it
B. Nature’s Cure for Snowblindness
C. Soldiers in Snow
D. Snow Vision

For a 400-year-old art form, operas had a bad fame: overweight actresses singing the words which are hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $ 145 a performance, opera goers also have a certain appearance in people’s mind: rich, well-dressed and old.
But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to bring the opera to the audience. It needs to keep it alive, the young and not-so-rich.
Opera producers have found that to attract this crowd, they need to make the opera closer to common people. That means no formal suits, old-styled theatre or band-breaking ticket prices. And because young people don’t or won’t come to the opera, companies are bringing the opera to them, giving performances in such unusual places as parks, libraries and public schools.
The Houston Grand O pera’s choice is the public library, where it performs “mobile operas”, shortened versions (剧本) of child-friendly operas. This summer’s production is Hansel & Gretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists’ Training Program.
67. Which is the main idea of this passage?
A. Opera is famous for its long history.
B. Opera is only performed for rich people.
C. Young people are not interested in opera.
D. Opera companies are trying to keep opera alive.
68. The underlined phrase “loosening their ties and kicking off their shoes” (paragraph 2) means
_______.
A. breaking up the old rules
B. changing the formal suits
C. making the audience at ease
D. advertising themselves
69. Opera companies prefer to perform short versions because ________.
A. it is hard to find long versions
B. short versions are easy to perform
C. they can perform in public libraries
D. they can make more people come to opera
70. The San Francisco Opera Company employs student actors in order to _______.
A. celebrate its 75th anniversary
B. reduce the cost
C. attract young people
D. make Cinderella popular
71. From the passage we can infer that ______.
A. the tickets for operas are very expensive
B. operas are performed in a difficult language
C. operas are not so popular an art form today
D. students enjoy performing operas very much

Dear Carol,
I wear braces (牙箍) and I know I look just terrible in them. Is there anything I can do to improve my appearance until they come off?
Connie N.
Philadelphia, PA Dear Connie,
Start by thinking about how good you are going to look when your braces come off. If you are negative about your appearance, people will pick that up right away about you. In the meantime there are several things that you can do to lift your spirits:
●Change your hairstyle. Be sure to get a good cut so that the shape of your hair will be
flattering to your face and also good for your type of hair (fine, thick, straight, curly, etc.) Choose a hairstyle that draws attention away from your face. Hair pulled back into a pony-tail or into a ball on top or slightly off-center can be attractive and practical for this purpose.
●Keep skin clean. If you choose to wear makeup, it should look natural. Blusher and lip gloss
in light tones of peach or pink are best.
●Be well-groomed. Neatness really counts. People see a total look about you before they ever
become aware of your braces. And first impressions are lasting ones!
72. Why did Connie write to Carol?
A.Because she really care about her clothes.
B.Because she cared much about her appearance.
C.Because her teeth were not good.
D.Because she didn't know how to make up.
73. Carol's idea about one's appearance is ______.
A.change your hairstyle and you will look beautiful
B.keep your skin clean and you will look good
C.neatness really counts
D.if you yourself don't think you look smart, neither will people
74. Carol tries to let Connie know that _______.
A.the deepest impressions one leaves on others is the first ones
B.spirits are important when we talk about one's appearance
C.there are some practical ways to draw people's attention away from where you don't feel
good
D.all of the above
75. The underlined word “count” means “________” in the passage.
A. say numbers in order
B. be of importance
C. not include
D. be accepted

My wife and I got he theater whenever we can. But before we buy tickets, we like to know if the play is good or bad. When a new play opens, we usually read the newspaper to get information
about it. Last week a new play opened at the theater. The newspaper story said it was very interesting so we decided to go on Saturday night.
My wife took a long time to make up her mind what to wear and we left our house a little late. By the time we got to the theater, the first act had already begun. We are sorry we missed part of the play, because the rest of it was very funny. The newspaper had been right. It was very good.
After the play was over, we met some friends we hadn’t seen for a long time. They wanted to go to a night club. It had been many years since my wife and I had gone dancing, but I finally agreed. By the time we got home, it was about two o’clock in the morning. I’m not accustomed to staying out so late and I was extremely tired.
When I was younger, I didn’t have the money to go out for an evening like this. Now that I can afford it, I don’t have the energy to r eally enjoy it.
