     Is the world too crowded? Well, that's a hard question to answer. It's all a matter of perspective (视角).
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 (十亿). 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 (相当于) too many
people. But everyone agrees that the more people there are, the more resources (资源) 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.

1. From the first paragraph we can know that _____.

A. Montana is too crowded

2. The population is increasing fast partly because _____.

A. people live longer than before

3. What was the world's population 100 years ago?

A. 450 million.
B. About 2 billion.
C. 40 billion.
D. 7 billion.

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

5. From the passage we can learn that the writer _____.

It is said that all dreams serve a purpose（目的）. While there is no agreement among scientists about why we dream, there are many ideas about the different kinds of dreams we have.
One common kind of dream is the repeating dream, in which the same story is repeated again and again, often for many months or even years. Some believe these are a sign people have a problem in their life and once that problem is gone then the dream will stop. Others think they are a way to help people remember something very important.
Another well-known kind of dream is the nightmare. The pictures and stories in such dreams make people very afraid and dreamers usually remember them far more clearly than normal dreams. The cause of such dreams may be seeing something terrifying such as a car accident or some deadly snakes. Others think such dreams may be trying to make a person pay attention to something that is dangerous in their life.
Daydreams happen during wake-time when we forget where we are or what we are doing and find ourselves in a made-up story or unreal world. We often daydream when we are doing something that is not interesting or exciting. They help us think about our future.
Lucid dreams are the most fun. These happen when dreamers suddenly understand that they are dreaming. Instead of waking up, they stay in the dream and are able to control what happens in the dream as if they are making a movie.
【小题1】The underlined word “they” (in paragraph 2) refers to “_________”.

A．dreams

B．problems

C．dream

D．scientists

【小题2】The underline word “terrifying” (in paragraph 3) is closest in meaning to _________.

A．frightening

B．interesting

C．disappointing

D．amazing

【小题3】When might a person daydream?

A．During a very interesting movie.

B．While playing at a fun park.

C．While listening to an uninteresting talk.

D．When making a movie.

【小题4】How do we know if we are lucid dreaming?

A．We can remember the dream very clearly.

B．We can control what happens in the dream.

C．We think that the dream is like a movie.

D．We feel very nervous after we wake up.

【小题5】What is the best title of the passage?

A．Daydream of You

B．Enjoy Your Dream

C．What Dreams Mean

D．Where Dreams Go
