第三部分阅读理解(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。

Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk, juice, eggs, and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other cultures.

A very popular breakfast food in America is the pancake－a thin, flat cake made out of flour and often served with syrup(糖浆). The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China.

Bagels, a round thick bread with a hole in the middle, are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe.

In the late 1800s, thousands of Jews from Eastern Europe traveled to the United States and brought the recipe for bagels with them. Today, New Y ork bagels are said to be the best in the world. Many people have them with cream cheese for breakfast on the go.

Doughnuts (usually spelled “donut” in the United States)came from France. They were served to American soldiers in France during World War I. After the war, American soldiers asked cooks in the United States to make doughnuts for them. Now, served with coffee, they are a very popular breakfast food across the United States.

56. The oldest breakfast food in the passage is______.

A. the pancake

B. the bagel

C. the doughnut

D. not mentioned in the passage

57. Which sentence is true for both bagels and donuts?

A. They both came from Europe.

B. They are both sweet.

C. They are both easy to make.

D. People in New York make them best.

58. Who brought bagels to America?

A. Polish people.

B. Chinese people.

C. Jewish people.

D. American soldiers.

59. Who served donuts to American soldiers during World War I?

A. French people.

B. Other American soldiers.

C. Jewish people.

D. Cooks from the United States.

A lot of us lose life's tough battles by starting a frontal(正面的) attack－when a touch of humor might well enable us to win. Consider the case of a young friend of mine, who hit a traffic jam on his way to work shortly after receiving an ultimatum(最后通牒) about being late on the job. Although there was a good reason for Sam's a being late－serious illness at home－he decided that this by－now－familiar excuse wouldn't work any longer. His supervisor was probably already pacing up and down preparing a dismissal speech.

Yes, the boss was, Sam entered the office at 9：35. The place was as quiet as a locker room(更衣室); everyone was hard at work. Sam's supervisor came up to him. Suddenly, Sam forced a grin and stretched out his hand. “How do you do！” he said. “I'm Sam Maynard. I'm applying for a job, which, I understand, became available just 35 minutes ago. Does the early bird get the worm？”

The room exploded in laughter. The supervisor clamped off a smile and walked back to his office. Sam Maynard had saved his job－with the only tool that could win, a laugh.

Humor is a most effective, yet frequently neglected(忽略), means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying “no”，criticizing, getting the other fellow to do what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialog may start a quarrel. For example, many believe that comedians(喜剧演员) on television are doing more today for racial and religious tolerance(忍受力) than people in any other forum.

60. Why was Sam late for his job?

A. Because he was ill.

B. Because he got up late.

C. Because he was caught in a traffic jam.

D. He was busy applying for a new job.

61. The main idea of this passage is ______.

A. Sam Maynard saved his job with humor

B. humor is important in our lives

C. early bird gets the worm

D. humor can solve racial discriminations

62. Which of the following statements can we infer from the passage?

A. Many lose life's battles for they are lacking in a sense of humor.

B. It wasn't the first time that Sam came late for his work.

C. Sam was supposed to come to his office at 8：30.

D. Humor is the most effective way of solving problems.

Across the globe, single parent homes are on the rise. In the US, the 2000 census (人口普查) showed 24.8 million, or nearly 24 percent of the nation's 105.5 million households, were traditional two－parent homes. By comparison, 9.8 million households, or 9 percent of all US households were headed by an adult raising a child alone. The 1990 census showed 26 percent of homes were led by a married mother and father, and 8 percent of homes were led by a single parent.

Similar increases occurred in other countries. In the UK, lone－parent homes increased from 3.3 percent in 1990 to 5.5 percent in 1999. Single parent households in Australia rose from 5.8 percent in 1990 to 7.6 percent in 1999. Belgium saw the increase from 1.8 percent to 2.7 percent during the same period of time. These countries tend to have greater acceptance of the single parent because there are fewer nearby family members to disapprove, Riche, a Census Bureau director, said.

Just as in the US, those changes raised new questions about how involved govenment should be in helping single parent families. Some research suggests children raised in two－parent families are better off than those who depend on one.

“The position of one－parent families in any country is very much a gender (性别) issue－women's opportunities, especially working－class women on low income，” said Sue Cohen, coordinator (协调员) of the Single Action Parents Network in England.

67. Not considering the exact number of the single－parent families, which country saw

the fastest rise rate in 1999, compared with 1990?

A．UK. B．Australia. C．America. D．Belgium.

68. What is the cause of the rise of single parent families across the globe?

A. The nearby family members have a favourable opinion.

B. A lone parent is well off enough to support his /her children.

C. A lot of problems have arisen in two－parent families.

D. We cannot get enough proving information from the text.

69. Which of the following is TRUE about the increase of single parent families according to the passage?

A. It will somewhat limit the growing population of younger generation.

B. Governments should take actions about the social problems brought about by it.

C. Single parent families are not looked down upon in any country mentioned here.

D. Generally speaking, the single parents needn't worry since they are highly paid.

70. Which of the following diagrams correctly shows the rise of single parent families in the US from 1990 to 2000?

A．B．C．D．、

范文：Some students think that it is useless for Senior Grade Two students to have art lessons. They have much pressure both in their studies and mind. They have to study hard every day in order to be admitted into good universities. They have no extra energy to take art lessons.

However, some other students think it is quite necessary for them to learn art. In their opinion, art can not only regulate the boring life but also mould their temperament and improve their creativity. The society in the future needs not only people who have much knowledge but also people who are creative. I think it is necessary for Senior Grade Two students to have art lessons even though they are busy with their studies.
