Question

閱讀下面的短文，并根據(jù)短文后的要求答題（請(qǐng)注意問題后的字?jǐn)?shù)要求）。

       Now scientists say that they can change the genetic makeup of certain animals so that their organs may be        humans. With this gene-altering technique to overcome our immune rejection to foreign organs, scientists hope to use pig hearts for transplants by the year 2010.

       Animal-rights activists say the whole idea of using animal organs is cruel and unjust. "Animals don't exist as tools for human beings, or for replacement parts," they protest. Some scientists also worry about unforeseen consequences of this technique. They fear such transplants may transmit unknown disease to humans.

       Others believe transplanting animal organs into humans is unnecessary. The millions of dollars spent on breeding cows and pigs for their organs could be better spent on health education  programs. Seventy-five per cent of the heart and liver disease cases that lead to a need for organ transplant are preventable, they say. The key is to convince people to have a healthy diet, and not to smoke or drink alcohol. Scientists could also use research funds to improve artificial organs.

       Still others believe that though new inventions and prevention programs may help, spending money to encourage more people to donate their organs is an even better idea. "Each year we lose 50,000 to 80,000 organs because doctors don't tell us about deaths, or because families say no," says Swasey, who had a heart transplant seven years ago. "If we educated enough people about organ donations, we could take everyone who needed an organ off the waiting list in a year."

72．The key is to convince people to have a healthy diet, and not to smoke or drink alcohol.

73．put into

74．I don’t agree. It’s cruel and unjust to use animals as organs donor. And it is likely to transmit unknown diseases to humans. We should spend more effort on health education programmes.

75．如果我們教育足夠的人捐獻(xiàn)器官，我們就可以在一年之內(nèi)把所有需要器官的人從等待的名單中刪除。
