最近，有小伙伴在询问最后阶段，考研英语该如何备考才最有效。最后阶段，我们应该将备考的重点放在复习和了解考试上，多去练习历年真题和模拟试题。下面，51题库考试学习网为大家带来考研初试的一些模拟试题，一起来看看吧。

The term“genetically modified”(G-M)is an offspring of another term：biotechnology，a word that‘s been around for about 30 years.Biotechnology was coined in the shadow of new techniques that allowed scientists to modify the genetic material in living cells.Roughly，that means imitating biological processes to produce substances that，arguably，benefit things like agriculture，medicine and the environment.

Proponents of G-M foods argue using biotechnology in the production of food products has many benefits：it speeds up the process of breeding plants and animals with desired characteristics;can be used to introduce traits that a product wouldn‘t traditionally have;can improve the nutritional value of products;and can produce cheaper and more environmentally-friendly fertilizers.And，say the supporters，a11 of this is done safely.Bart Bilmer，an officer of biotechnology at the Canadian Food Inspection Agency，reinforces this.He says before being put on the shelves，all foods go through rigorous tests to ensure they’re up to snuff.The standard for“safe”is the food that‘s already being sold in grocery stores.It’s called the principle of substantial equivalence.And there‘s no doubt in Bilmer’s mind that it‘s a system that’s working and working well.

Advocacy groups，like the Council of Canadians and Greenpeace，don‘t see things quite the same way.They cite studies done by groups such as the British Medical Association which argue G-M foods could have disastrous consequences to our health.1)To the groups on this side of the issue，that“could”provides more than enough reason to proceed with extreme caution，something they say isn’t being done at present.Those on this side of the debate say there are a number of problems with the current approach to G-M foods.To begin with，they argue the notion of substantial equivalence is not a standard they trust.They want a new testing system independent from the industry.As well，G-M critics say enough time hasn‘t passed to study the long-term effects of the foods.Without knowing，argues Jennifer Story of the Council of Canadians，Canadians are“part of this giant experiment involving a radical and frontier science”。

One side says the foods on the shelves of Canada‘s grocery stores are safe.The other side says they’re not so sure.Both sides agree consumers may be confused with the information out there but don‘t agree on how to address that confusion.One side says the answer lies’in voluntary labels，the other says mandatory ones are the bare minimum.2) Whatever the case， it\'s a debate that makes us consider the role technology has in our lives.What makes this debate unique is that every meal we eat is at its very core.And that fact means one thing：it‘s an issue to be discussed not only around policy tables，but dinner tables.

1. The expression“are up to snuff”(Para.2 )probably means____.

[A]be healthy [B]be pleasant to taste

[C]meet the standard [D] be nutritious

2. The“principle of substantial equivalence”(Para.2 )is one by which____.

[A]G-M foods can be produced and processed

[B]one can define the safety of G-M foods

[C]foods can be genetically modified up to standard

[D]foods can be tested before they are sold at grocery stores

3. Those who advise taking a cautious attitude toward G-M foods warn that____.

[A]G-M foods will have disastrous consequences to people‘s health

[B]the long-term effects of G-M foods remain largely unknown

[C]most G-M foods do not meet the principle of substantial equivalence

[D]most fertilizers used in raising G-M foods are harmful to the environment

4. What Jennifer Story says implies____.

[A]she considers genetic food modification desirable

[B]she believes G-M food will have disastrous consequences to our health

[C]she predicts more and more Canadians will like G-M foods

[D]she takes a cautious attitude towards food modification

5. The author‘s attitude towards the issue of G-M food is____.

[A]positive [B]negative

[C]radical [D]impartial

参考答案：

1. [C] 这是一个俚语，意为“符合标准的”。第二段中该句的下一句实际上解释了该词组的意思。

2. [B] 该句的上一句实际上说明了其意思。

3. [B] 在第三段，认为应该慎重对待这种新型食物的人提到了两点理由：一是他们认为目前测试其安全与否的标准不可靠;二是认为这种食物投放市场的时间尚短，还没办法研究其长期效应(long-term effects)。

4. [D] 在第三段最后一句她说，加拿大人毫无意识地成为一种全新的前沿科学的试验品。她说的这一句话与上一句话的意思应该是一致的。由此推断，在她看来，人们应该谨慎做事，因为人们还不了解新型食物的长期效应。

5. [D]意为：客观的。作者列举了拥护者和反对者的意见，对于孰是孰非并没有提出自己的看法，所以在最后一句作者指出，问题还将继续争论下去。
