单选题 Protests at the use of animals in research have taken a new and fearful character in Britain with attempted murder of two British scientists by the terrorist technique of the pre-planted car-bomb.
The research community will rightly be alarmed at these developments, which have two objectives: to arouse public attention and to frighten people working in research with animals. The first need is that everything should be done to identify those responsible for the crimes and to put them on trial. The Defense Research Society has taken the practical step of offering a reward of 10,000 pounds for information leading to those responsible, but past experience is not encouraging. People are unlikely to be tempted by such offers. The professional police will similarly be confronted by the usual problem of finding a needle in a haystack.
That is why the intellectual community in Britain and elsewhere must act more actively in its own defense. There are several steps that can be taken, of which the chief one is to demand of all the organizations that exist with the declared objectives of safeguarding the interests of animals that they should declare dearly where they stand on violence toward people. And it will not be enough for the chairmen and chairwomen of these organizations to make placatory (安抚的) statements on behalf of all their members. These people should also undertake that it will be a test of continuing membership in their organizations that members and would-be members should declare that they will take no part in acts of violence against human beings. Even such undertakings would be fully effective: people, after all, can lie. But at least they would distinguish the organizations entitled to a continuing voice in the dialogue with the research community about the rights of animals in research from the organizations that deserve no say.

单选题 The underlined words "these developments" in paragraph 2 most probably refer to ______.

【正确答案】 A

【答案解析】参见第一段：Protests at the use of animals．．．the pre-planted car-bomb．以及第二段第一句The research community will rightly be alarmed at these developments．．．(针对用动物作试验的抗议活动在英国出现新的令人生畏的发展迹象——有人试图通过安置汽车炸弹的恐怖手段谋害两名英国科学家。对这些发展情况，科研群体完全有理由感到惊恐。)

单选题 What does the author think will likely happen to the car-bomb planting terrorists?

单选题 What does the underlined word "they" in paragraph 3 refer to?

【正确答案】 B

【答案解析】指代关系判断题。参见第三段第二句：There are several steps that can be taken，of which the chief one is to demand of all the organizations that exist with the declared objectives of safeguarding the interests of animals that they．．．(目前已采取数项措施，其中主要的一项是要求所有以保护动物利益为明确目标的组织清楚地声明他们在反人类的暴力行为问题上的立场)该长句结构“demand of all the organizations (that exists with．．．animals)that．．．”是动词词组“demand sth of sb”的变异用法，其中“that exists with．．．animals”为修饰organizations的定语从句。

单选题 The author's purpose in writing this article is to demand that animal-protecting organizations ______.

【正确答案】 B

【答案解析】全文主旨题。本文第一、二段提及有人为抗议利用动物作试验而对科学家采取恐怖活动，警方与“防御研究协会”随即对恐怖分子展开追查，但破案成功的概率不大。因此作者在第三段提出，研究人员要更加积极地自我防卫，采取有效措施，其中一项措施就是要求动物保护协会明确表态不参与暴力活动。参见第三段第二句与倒数第三句．．．members and would-be members should declare that they will take no part in acts of violence against human beings，由此可见，作者的写作目的是要求动物保护组织放弃暴力。

单选题 In the author's opinion ______.

【正确答案】 D

【答案解析】细节题。参见第三段第一、二句：That is why the intellectual community in Britain and elsewhere must act more actively in its own defense．There are several steps that can be taken．．．(因此无论是英国还是其他地方的知识分子团体都必须积极行动起来保护自己，可以采取多项措施……)
