第三部分:阅读理解:(共20小题;每小题2分,满分40分)阅读下列短文,从每题所给的四个选项中,选出最佳选项。

(A)

What makes a house a home? A home is a place of companionship with people in it who love each other, who are harmonious (和谐的) and closer with one another than with those in the workplace or with classmates at school. A home is a place that’s so magnetic(有吸引力的) that it’s difficult to leave. In a home there is love, sharing and appreciation, and the members help one another.

I have seen families on the street. But if they live, sleep, talk, and eat together, they are a family, even if they are poorly off. You don’t need a roof to make a home. The truly homeless are some of the rich people who build multi-million-dollar houses and are too busy to really live in them. The truly homeless are those who have turned their home into a hotel lobby. The parents work and the children misbehave. They don’t talk and eat together every day. They rarely see each other. The truly homeless people are those with babysitters, caretakers, gardeners and maids. However, people are unaware of this, as they are too busy making money outside the home that they don’t live in. This is another way of looking at the rich and the homeless. Who is to be pitied?

Control of the computer and the Internet is also important to make a house into a home. If the computer is on all the time, the house turns into an office, even if everyone is at home. Many homes these days are just offices. Human communication has stopped. The computer eats up all the time that one should be giving to others within the home. Using the computer moderately gives us time for play and communication, not with a screen, but with other people.

56. Which of the following may serve as the best title for this passage?

A. How to make a house a home?

B. What makes a house a home?

C. Who are truly homeless?

D. What is a home for?

57. The purpose of the first paragraph is to _________.

A. tell us that where there is home there is love

B. tell us what people think a home is

C. tell us the author’s concept(理解)of home

D. tell us how to have a happy home

58. The underlined word “those” refers to ________.

A. people who build multi-million-dollar houses

B. people who have lost their family members

C. people who don’t spend time with the family

D. homeless families living on the street in America

59. Which of the following is FALSE according to the passage?

A. A home is a place where you are willing to stay.

B. Even the poorest people can have a happy home.

C. Computers and the Internet are important for a happy home.

D. Sometimes it’s the rich that should be pitied.

     Today, there's hardly an aspect of our life that isn't being upended (颠覆) by the tons of information

available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in

constant touch with each other via electronic mail. "If the automobile and aerospace technology had

exploded at the same pace as computer and information technology," says Microsoft, "a new car would

cost about $ 2 and go 600 miles on a small quantity of gas. And you could buy a Boeing 747 for the cost

of a pizza."

     Probably the biggest payoff, however, is the billions of dollars the Internet is saving companies in

producing goods and serving for the needs of their customers. Nothing like it has been seen since the

beginning of the Industrial Revolution, when power-driven machines began producing more in a day than

men could turn out in nearly a year. "We view the growth of the Internet and e-commerce as a global

trend," says Merrill Lynch, "along the lines of printing press, the telephone, the computer, and electricity."

     You would be hard pressed to name something that isn't available on the Internet. Consider: books,

health care, movie tickets, construction materials, baby clothes, stocks, cattle feed, music, electronics,

antiques, tools, real estate, toys, autographs of famous people, wine and airline tickets. And even after

you've moved on to your final resting place, there's no reason those you love can't keep in touch. A

company called FinalThoughts.com offers a place for you to store "afterlife e-mails" you can send to

Heaven with the help of a "guardian angel".

     Kids today are so computer literate that it in fact ensures the United States will remain the

unchallenged leader in cyberspace for the foreseeable (能预测的) future. Nearly all children in families

with incomes of more than $75,000 a year have home computers, according to a study by the David and

Lucile Packard Foundation. Youngsters from ages 2 to 17 at all income levels have computers, with 52% of those connected to the Internet. Most kids use computers to play games (some for 30 hours or more

a week), and many teenage girls think nothing of rushing home from school to have e-mail chats with

friends they have just left.

     What's clear is that, whether we like it or not, the Internet is an ever growing part of our lives and

there is no turning back. "The Internet is just 20% invented," says cyber pioneer Jake Winebaum. "The

last 80% is happening now."

1. What can we learn from the Microsoft's remark?

A. Today's cars and airplanes are extremely overpriced.

B. Information technology is developing at an amazing speed.

C. Information technology has reached the point where improvement is difficult.

D.There's more competition in information technology industry than in car industry.

2. The author gives the example of FinalThoughts.com to make the point that____.

A. there are some genius ideas on the Internet

B. almost anything is available on the Internet

C. people can find good bargains on the Internet

D. some websites provide novel services to increase hits

3. What can we learn from the fourth paragraph?

A. There is a link between income and computer ownership.

B. Many American children don't put computers to good use.

C. Studies show that boys are more computer literate than girls.

D. The U.S. will stay ahead in the information technology in years.

4. Which sentence has the phrase that possesses the same meaning as the one underlined

    in the fifth paragraph?

A. Some can tell you that he has changed their lives, while others think nothing of him.

B. Think nothing of it. It was my pleasure.

C. He thinks nothing of staying up all night in the Caf? bar.

D. He thinks nothing of the pain in his back for the moment.

5. What is the message the author intends to convey?

A. The Internet is going to get firm hold of our lives some day.

B. The Internet is going to influence our lives even more greatly.

C. We should have a positive attitude towards the changes the Internet brings.

D. Children should be well prepared for the challenges in the information age.
