Fourteen-year-old Sean MeCallum lay in a hospital bed waiting for a new heart. Without it, Sean would die. Sean’s case is not unusual. Everyday many people die because there just aren’t enough human organs to go around.
Now scientists say they can alter the genetic make-up of certain animals so that their organs may be acceptable to 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 2008.
That prospect, however, has stirred up strong opposition among animal right activists. They protest that the whole idea of using animal is cruel and unjust. Some scientists also fear such transplants may transmit unknown diseases to humans.
Others believe transplanting animal organs into humans is unnecessary. Millions of dollars spent on breeding pigs for their organs could be better spent on health education programs. They believe seventy-five percent of the heart disease cases that had lead to a need for organ transplant are preventable. The key is to convince people to eat healthfully, 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. If enough people were educated about organ donations, everyone who needed an organ could be taken off the waiting list in a year.
Not only is the gene-altering technique a technical issue, according to the passage, but also it______.
选项
A、introduces an issue of inhumanity
B、raises the issue of justice in medicine
C、presents a significant threat to the human nature
D、pushes the practice of organ transplant to the limits
答案
A
解析
细节题。本题题意是:“本段文字认为,基因改变技术不仅是技术问题,还提出了人道(不人道)的问题。”第二段告诉我们有些科学家说,可以通过基因技术改变猪的基因使之适用于人类。第三段则告诉,我们动物权利激进分子反对这一做法,认为太残忍、对动物不公平。所以选A。
