    题目列表(包括答案和解析)


    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( 胡萝卜素). 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（大脑）, and then you know what you’re looking at. Your eye can only turn light into messages when it has a special chemical(化学物质). 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.
    【小题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
    【小题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.

    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.
    【小题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.
    【小题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

    Do you know of anyone who uses the truth to cheat? When someone tells you something that is true, but leaves out (略去) important information that should be inside, he can give you a false picture.
    For example, someone might say, “I just won a hundred dollars on the lottery(彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”
    This guy is a winner, right? Maybe, maybe not. We then discover that he bought $ 200 worth of tickets, and only one was a winner. He’s really a big loser!
    He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half truths are not technically lies, but they are just as dishonest.
    Some politicians (政客) often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and got three million jobs. Then she tries to get another term. One of her opponents (竞争对手) says, “During Governor Smith’s term, the state lost one million jobs!” That’s true. However, an honest statement would have been, “During Governor Smith’s term, the state had increased two million jobs.’’
    Advertisers will sometimes use half–truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to say that they only asked ten doctors and nine of them work for the Yucky Company.
    This kind of cheating happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
    小题1:We may infer that the author believes people should ________.
    A．buy lottery tickets if possible
    B．make use of half–truths
    C．be careful about what they are told
    D．not trust the Yucky Company
    小题2:How many examples does the writer give to show how the truth is used to cheat?
    A．OneB．TwoC．Three D．Four
    小题3:Which of the following is TRUE according to the passage?
    A．Using half truths is against the law.
    B．Technically, half truths are in fact lies.
    C．Yucky Pills is a very good medicine for toothache.
    D．Governor Smith did a good job during her last term.
    小题4:Which of the following best expresses the main idea of the passage?
    A．He’s really a big loser!
    B．Sometimes the truth can lie as well.
    C．Advertisers will sometimes use half truths.
    D．It’s against the law to make false statements.
