Is the world too crowded? Well, that’s a hard question to answer. It’s all a matter of perspective(視角).In Montana, you might drive for a mile in any direction and not see another human being. In Macao, 60,000 people live in every square mile!
What is true is that the world’s population doesn’t stay the same. It has been increasing at a very fast rate(比例).That’s in part because in each generation(代) these are more people who then have children than in the last generation.
Five hundred years ago, the population of the world was about 460 million. In 1900,the world’s population was under 2 billion(十億).Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Wow! Now that’s a whole lot of people! Soon the world’s population will probably reach 7 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth equals(相當(dāng)于) too many people. But everyone agrees that the more people there are, the more resources(資源) the world needs to feed, house and take care of all of them, and the more need there is to think carefully about how we live and use the earth’s resources.
小題1:From the first paragraph we can know that ­________.
A．Montana is too crowded
B．Macao is too crowded
C．the world is too crowded
D．the world is not too crowded
小題2:The population is increasing fast partly because ________.
A．people live longer than before
B．there are less wars than before
C．medicine is developing faster than before
D．more couples now would like to have children than before
小題3:What was the world’s population 100 years ago?
A．450 million.B．a(chǎn)bout 2 billion.
C．40 billion.D．7 billion.
小題4:The writer thinks that with the population increasing, we should ________.
A．find more resources
B．use more resources
C．think about our ways of living
D．move to other places
小題5:From the passage we can learn that the writer ________.
A．thinks the world already has too many people
B．thinks the world can feed no more than 7 billion people
C．is not sure when the world’s population will reach 7 billion
D．is not sure what the largest population that the world can feed is

小題1:B
小題2:D
小題3:B
小題4:C
小題5:D
本文主要講述了人口的不斷增長(zhǎng)，以及人口的增長(zhǎng)和資源的問題。
小題1:根據(jù)第一段最后一句：在Montana你向任何方向開車一英里，可能看不到任何人，但是在澳門每平方英里有6萬(wàn)人。可以看出澳門的人多，故答案選B。
小題2:根據(jù)第二段的最后一句that’s in part because in each generation there are more people who then have more children than in the last generation..可知答選D。
小題3:根據(jù)第三段的第二句In1900, the world’s population was under 2 billion.在1900年世界的人口不足兩億，可知答案選B。
小題4:根據(jù)文章的最后一句可以得知“由于人口的增長(zhǎng)，我們可以考慮我的生活方式了”，因此，答案選擇C項(xiàng)。
小題5:由最后一段中的But there is a lot of disagreement about just how many people on earth equals too many people.可以判斷得知。

Americans think a great deal about time. From childhood they learn to value（珍惜）time. As children, they are taught to be on time to go to school, to do work and to do everything. When they are having a good time, they say that time flies. When a person is dying, they say he is living on borrowed time. Time is money. Time is knowledge. Time is everything in America. A working American has to work hard for 8 hours a day or 40 hours a week. This is the working time. In his free time, he also works hard for more money. Even Saturday and Sunday are filled with（充滿）activities. In the street you can hardly see a man who walks slowly. They walk very fast. In fact, they are running. They love time because time brings them money, comforts and progress. But sometimes they also hate time, for they feel they have become servants（仆人）of the clock.
