Part Ⅵ READING COMPREHENSION (開始Part Ⅵ READING COMPREHENSION計時)
Direction: In this section there are four passages followed by fifteen questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the correct answer. Mark your choice on your answer sheet.
TEXT A It is impossible to reverse knowledge, but it is societys prerogative to state which pieces of knowledge should remain unused. "Can do" never implies "must do". It is rightly illegal to clone a human being in the UK, but it would not be beyond human perversity for someone to try to do it elsewhere in the world. One UK doctor, who has publicly condemned the very idea, claims to have had people offering themselves for cloning or asking to have it done to loved ones. It would appear that some are attracted by the idea, but maybe they have not fully understood the implications. Even supposing someone would be stupid enough to try, there are many serious obstacles to be overcome. There is firstly the risk of imprisonment. A scientist would take the risk of ostracism from a disapproving medical and scientific establishment, and know that a journal would possibly refuse to publish any paper on the subject. Then he or she would have to persuade or induce dozens of people to take part in prolonged illegal experiments. It would need donors, egg cell recipients and surrogate mothers in fairly large numbers, to take part in experiments. Abnormally large progeny have resulted in animal cloning done to date, which suggests that there are serious risks to the health of the mother and potential embryo. In order to prevent the genie from coming out of the bottle, there should be immediate moves to set up, if possible, an internationally binding treaty to ban experiments regarding human cloning worldwide.
66. This short article is mainly about ______
A) that it's illegal to clone human beings.
B) what you do with a Genie out of the Bottle and why you do so.
C) how a scientist could do this kind of experiments successfully though it's illegal.
D) the bad effects that "cloning humans" brings.
67. Why does putting "cloneman" to practice face so many obstacles?
A) All the people oppose it.
B) The technique is not mature.
C) Its against the humans ethic.
D) Both B and C.
68. In order to prevent the genie from coming out of the bottle, we should do all the followings except that ______
A) we should really know the implication carried by the idea of cloning a human being.
B) we shouldnt let us be used for the illegal experiment done by some ambitious scientists.
C) we should do our best to appeal to stopping all the "clone" experiments whether its on men or on other species.
D) we should make our efforts to put a worldwide ban on the experiments on humans.
69. All of the following are the obstacles that a doctor can meet when trying to clone a human being except ______
A) serious risks to the health of the surrogate mother.
B) the risk of imprisonment
C) the risk of being executed.
D) the risk of resistance from medical establishments.
TEXT B No one knows who was the first to invent the dice as we know them. What is remarkable is that they have remained virtually intact across national boundaries and all through the age -- small cubes marked by dots from 1 to 6, so placed that the sum of the dots on opposite sides equals 7. Dice much like those used today were found in China in unearthed cultural relic dating from 600 BC and in ancient Egyptian tombs dating from 2000 BC, as well as in the ruins of Babylon. The playing of dice was popular in Greece and even more so in Rome, and dice were used throughout the Middle Ages. In the simplest play with dice each player throws, or shoots, for the highest sum. In China and in the United States the most popular dice game is played with two dice. The number of random numbers that can be expressed by two dice is very limited; the number are. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, all eleven of them. The most probable throw is 7. The probability of 7 is six times that of 12. Therefore it would be ideal if a new kind of dice could be invented with an equal distribution of chances for each number. Well, such dice have already been invented by a British amateur astronomer by the name Aires. The new version, which the inventor calls "heartbreak dice", also consists of two dice. But the number of random numbers that can be expressed by the new dice is more than three times that of the traditional ones, and the chances for each number are strictly equal.
70. According to passage one, we Chinese had played dice ______
A) more than 2500 years before.
B) 1400 years earlier than Egyptians had done so.
C) in the Middle Ages.
D) just a little earlier before Christ was born.
71. Which of the following statements on the dice in China is true?
A) The dice in ancient China was quite different from what it is today.
B) The dice in China is very different from the ones in other countries.
C) In China, people never play dice games with only a dice.
D) The rule of playing in dice game in China is the same as the ones in other countries -- to get the highest sum.
72. In regarding to the new kind of dice, we can know that ______
A) it isn't a practical thing though raised by an Englishman in principle.
B) it is also named "Aires" though it's called "heartbreak dice" at last.
C) it's famous for the equal distribution of chances for every possible number.
D) it also uses digits from 1 to 6 on it.
