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.
小題1:The underlined word “they” (in paragraph 2) refers to “_________”.
A．dreams
B．problems
C．dream
D．scientists
小題2:The underline word “terrifying” (in paragraph 3) is closest in meaning to _________.
A．frightening
B．interesting
C．disappointing
D．a(chǎn)mazing
小題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.
小題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.
小題5:What is the best title of the passage?
A．Daydream of You
B．Enjoy Your Dream

It was so dark outside the car window that it was hard to see anything.
“ Can I have a carrot, Mom?” Bruce asked.
“I don’t have any carrots,” his mom said. “How about an apple?”
“No,” said Bruce. “It has to be a carrot.”
“Why do you want a carrot?” asked his mom
“You always say carrots help your eyes.” said Bruce. “If I eat one now, it might help me see in the dark.”
Would eating a carrot really help Bruce? What is special about carrots? What makes a carrot special is its color. Carrots are orange because they contain(包含) bta-carotene( 胡蘿卜素). Beta-carotene is a way of saying vitamin A. Your eyes need vitamin A. It helps them work.
When light hits your eye, very small parts inside turn the light into messages. The messages go to your brain（大腦）, and then you know what you’re looking at. Your eye can only turn light into messages when it has a special chemical(化學物質(zhì)). Your eyes use vitamin A to make the special chemical. Every time your eye changes light into messages, a little bit of the chemical is used up. By the end of the day, you’ve looked at hundreds of things. That uses up a lot of the chemical. Your eyes need to make more.
What should you eat if you don’t like carrots? Don’t worry. Other fruits and vegetables have vitamin A, too. The secret is in their color. Most orange or red fruits and vegetables contain beta-carotene, or vitamin A, Sweet vegetable, red peppers（胡椒）, Mangoes(芒果) are a few foods that have the same orange secret.
小題1: Bruce wanted a carrot because he thought _______.
A. he liked it
B. it could help him see in the dark
C.  it was sweet and delicious
小題2:How does vitamin A help your eyes work?
A. The special chemical can stop your eyes from using up vitamin A.
B. The special chemical is used to make Vitamin A which turns the light into messages
C. Vitamin A is used to make the special chemical which turns light into messages.
小題3: Which of the following is NOT true according to the passage?
A. Carrots are orange because they store beta-carotene.
B. Any food which is orange or red must have some Vitamin A.
C. Most fruits that are orange or red store some beta-carotene or Vitamin A.
小題4: Sweet vegetable, red peppers, and mangoes don’t have the same orange secret, do they?
A. No, they don’t.     B. Yes, they do.     C. I’m not sure.
小題5: The passage mainly tells us that _______.
A. we can’t see in the dark unless we eat many carrots every day
B. we can’t see unless we eat a lot of orange or red food every day
C. we should eat some food containing vitamin A so that we can see well
