    7．This passage mainly tells us . A．the main types of twins B．what has been found out about twins C．how twins are formed D．how a scientist studied twins C There were two interesting pieces of news items in the paper a few years ago. One was about a man who received a bill from the telephone company for $ 2,000 a month for doing nothing. The connection between the two news items is simple; computers-the best invention of the 20th century. The telephone bill came from a computer which made a terrifying mistake; that man’s bill was only $ 23.26. The other item was not as amusing. A man walked into the unguarded computer room of a large packaged food company and expertly programmed the computer to pay him $ 2,000 a month for raw meat which he “supplied to the company. Of course he never sent the meat, but he certainly received the money . The computer wrote out a bill, and even “signed it. It was only a random check that uncovered the trick. It could be happening in thousands of other companies all over the world. Computers are not the magical workers that some people say they are. They make mistakes, they’re sometimes slower than human beings and they’re easily fooled. The US used to conscript people with the help of a computer. The army sent out a card, which had to be filled in and sent back. It was easy to avoid being called up simply by spreading candle-wax(腊) on the card. The computer couldn’t read the card, and did nothing with it. It’s in our everyday life that computers cause many problems. Let’s get back to using people instead of computers, before a mistake that we can’t put right. 【查看更多】

    　　There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in the mother's body which divides to form two separate babies. Identical twins look the same, and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separate eggs at the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.

    　　In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.

    　　There is a third type of twins, but it is a very unusual one. Twins which are joined together at birth are known in western countries as Siamese twins.

    (1)It is difficult to tell identical twins apart because ________.

    [　　]

    A．they are dressed in the same clothes

    B．they are dressed in the same color

    C．they are very alike

    D．they are standing side by side

    (2)If the twins are easy to tell from each other, they are ________.

    [　　]

    A．very probably non-identical twins

    B．actually not brothers or sisters

    C．surely identical twins

    D．always a brother and a sister

    (3)Which of the following is NOT true according to this passage?

    [　　]

    A．In the 1970s and 1980s a scientist did some research into the two main types of twins.

    B．In the week of tests, he tested their speed of thinking, their speech, their memory and some other things.

    C．There were twins who had been separated from each other as soon as they were born.

    D．Very often, separated twins were found to choose things of the same kind, the same shape and the same color.

    (4)This passage mainly tells us ________.
