【题目】阅读理解
B
What will man be like in the future—in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller, so we may assume (假定) that man will continue to grow taller. Again, as time goes on, we shall have to use our brains more and more. This is likely to bring about a physical change to the head, in particular, the forehead will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs, which, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.
Perhaps all these give the impression that in the future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us.
【1】What does the passage mainly tell us?
A. Man’s life will be different in the future.
B. Future man will look quite different from us.
C. Man is growing taller and uglier as time passes.
D. Man’s organs’ functions will be weaker.
【2】What serves as the evidence that man is changing?
A. Man’s hair is getting thinner and thinner.
B. Man has got stronger eyes now than he ever had.
C. Man’s arms and legs have become lighter and weaker.
D. Man has been growing taller over the past 500 years.
【3】What can learn about a human being in the future?
A. He thinks and feels in different ways.
B. He has smaller eyes and wears better glasses.
C. He is hairless because hair is no longer useful.
D. His fingers grow weaker because he doesn’t use them.
【4】According to the passage, we can learn that ________.
A. human beings will become less attractive in the future
B. less use of a part of the body will become weaker
C. human beings hope for a change in the future life
D. future life is always predictable

【题目】阅读理解
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。
As I was walking home, a boy seemed to be singing a song in a very low voice, walking in front of me and carrying some of the same high school books I had with me. I caught up to him, and said “Hello”. I could tell he was startled, and dropped one of his books. I picked it up and as I handed it to him, he said “Thank you” in a strange way, like with a strong accent (口音).
We soon began walking together and talking. It turns out he was in my science class, and I didn’t even know it!
His name was Ahmad, and his family had just moved here this school year. He invited me into his house, and his family treated me like a special guest, which made me feel very welcome. He said hospitality (好客) is very basic to his culture, and strangers were always treated very kindly. His mom brought out some great food, and offered me some tea. Ahmad’s father and two sisters wanted to hear all about me and my family, and my schooling.
Ahmad’s whole family had to leave their lifelong home because war had broken out, and it wasn’t safe there anymore. They left with only what they could carry. His family was happy to feel safe, and they got used to American culture quickly. They seemed pleased that Ahmad had brought a friend home to meet them.
And as my friendship with Ahmad has continued, I now realize that the world is so much bigger than I thought! I also realize that your friends don’t have to be just like you. Differences make the world go round.
【1】What does the underlined word “startled” in Paragraph 1 mean?
A. Excited. B. Moved. C. Surprised. D. Interested.
【2】Why was the writer treated like a special guest by Ahmad’s family?
A. They liked strangers who came to their home for help.
B. They wanted to know more information about the writer.
C. Strangers were always treated very kindly in their culture.
D. The writer was an American and knew much about their culture.
【3】Where does the writer probably come from?
A. Canada. B. America. C. China. D. Australia.
【4】What can we learn from the passage?
A. People from different countries can be good friends.
B. Friends need different cultures and different accents.
C. Your friends should have a lot of things the same with you.
D. You can’t make friends with people from other countries.
