Agricultural biotechnology seems to attract a lot of attention these days. The problem is that the debate on this topic seems to have been hijacked by extremists on both sides; environmentalists crying disaster and corporate spokespersons telling us soothingly that there's nothing to worry about. Both extremes are wrong. Certainly global disaster isn't just around the corner. On the other hand, with the introduction of any remarkable new technology, unforeseen consequences are inevitable. One possible consequence is addressed in detail by Charles C. Mann in this issue'

s cover story, \Goes Wild\Mann reveals that crops genetically engineered to produce or resist pesticides could interbreed with wild plants, giving rise to \weeds\that could be very hard to eradicate and might choke food crops. And the fact is that science can't yet tell us whether to be alarmed. Why are we still in ignorance on this important issue? One reason is that the biologists who engineer genes into plants aren't trained to think about the whole organism and its habitat; they're molecular folk, lacking an ecological perspective. Another reason is the patchwork of US regulatory agencies that govern agricultural biotech; the Food and Drug Administration (FDA), the Environmental Protection Agency (EPA), and the Department of Agriculture (USDA). Mann writes that none of these agencies is responsible for superweeds, which could grow between the bureaucratic cracks. The FDA doesn't look at plants engineered to express pesticides, because pesticides are exempt from the agency's reach. The EPA is required to treat such foods as pesticides and simply establish human tolerances for each compound. USDA tries to make sure the crop grows as the producer says it will. There's only one thing omitted from this patchwork; the public interest. To stitch it back in two things are needed. One is additional research, from biotech companies and the federal government on the ecological consequences of genetic engineering. The other is a revision of the regulatory framework to make at least one of the agencies responsible for testing the environmental consequences of agribiotech. These changes would acknowledge the growing impact of this remarkable new technology and help us steer a course between wrongheaded extremes.

The author thinks that the biologists who engineer genes into plants ______.

A . are nothing more than any other substances because they are made of molecule too

B . pay special attention to living things and their relation to their environment C . insert the genes of one species among the genes of another and test the environment consequences

D . modify the genes of our food crops without considering the influence on the whole organism

正确答案:modify the genes of our food crops without considering the influence on the whole organism

题目详解:了解作者对biologists的总的看法后再做答。作者的观点是:the biologists who engineer genes into plants aren't trained to think about the whole organism and its habitat.

2. The disadvantage of the patchwork of US regulatory agencies that govern agricultural biotech is that ______.

A . one thing is omitted from the patchwork; human tolerance for pesticides B . pesticides are exempt from FDA's reach

C . there is bureaucratic cracks and the public interest is ignored D . none of these agencies is responsible for wild plants

正确答案:there is bureaucratic cracks and the public interest is ignored

题目详解:不能被一些细节的描写所蒙骗。所有细节都指向一个根本性的问题。注意这样概

括性的表达:Mann writes that none of these agencies is responsible for superweeds, which could grow between the bureaucratic cracks. 和There's only one thing omitted from this patchwork: the public interest.

3. In the last paragraph, the author thinks that ______.

A . additional research on the ecological consequences of genetic engineering should put the public interest at the core

B . to acknowledge the growing impact of the genetic engineering is to be ready for global disaster

C . it's necessary to establish new agencies to take responsibilities for testing the environmental consequences of agribiotech

D . it's necessary to stitch the public interest in wrongheaded extremes

正确答案:additional research on the ecological consequences of genetic engineering should put the public interest at the core

题目详解:要理解:There's only one thing omitted from this patchwork: the public interest. To stitch it back in two things are needed. One is additional research也就是说在试验研究中要考虑公众利益。

4. Which of the following statements is true of \ A . Superweeds could eradicate food crops.

B . Superweeds could hinder food crops' growth. C . Superweeds could grow between cracks.

D . Crops genetically engineered to resist pesticides could make superweeds grow high.

正确答案:Superweeds could hinder food crops' growth.

题目详解:文中句子:crops genetically engineered to produce or resist pesticides could interbreed with wild plants, giving rise to \that could be very hard to eradicate and might choke food crops.是说基因工程抗虫的作物与野草杂种繁殖,产生superweeds, 这种superweeds可能很难斩草除根,并阻碍农作物的生长。

\is a word that is used carelessly today. It is used to refer to matters of taste, belief, and judgment. This casual use would probably cause little confusion if people didn't attach too much importance to opinion. Unfortunately, most to attach great importance to it. \have as much right to my opinion as you to yours, '' and ''Everyone's entitled to his opinion, '' are common expressions. In fact, anyone who would challenge another's opinion is likely to be branded intolerant.

 Is that label accurate? Is it intolerant to challenge another's opinion? It depends on what definition of opinion you have in mind. For example, you may ask a friend “what do you think of the new Ford cars?\And he may reply, \my opinion, they're ugly.\In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, ''It's pointless to argue about matters of taste.\

 But consider this very different use of the term. A newspaper reports that t

he Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not shale their personal preferences, their mere likes and dislikes, they stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation.

 Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence.

 Is everyone entitled to his opinion? Of course, this is not only permitted, but also guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others.

题目详解:问题中\free to act on one's opinion\指的是最后一段的最后一句\so long as, in doing so, we do not harm others\由此,可以看出选项中的\mean that one has the right to do things at will\和本句的语义相关。

All that we really need to plot out the future of our universe are a few good measurements. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we do not know about the way the universe is put together. But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.

Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we cannot. There is no ambiguity if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.

When we think about the future of the universe, we can see our \many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed. ________________________________________
