Passage Four
Why haven’t British government bodies initiated any studies
A．Because they do not take the problem of sleepy drivers on motorways as of great significance.
B．Because they have not been aware of the seriousness of the problem of sleepy drivers.
C．Because they have no figures on the number of accidents caused by drivers’ sleepiness.
D．Because they plan to support relevant researches or a general study on "driver behaviour".
参考答案：A
解析：
[分析]： 因果关系的判断和理解 原文提到英国政府还没有对睡眠引发车祸的问题进行任何研究，通过上下文羊系，听者可判断其后的内容The Department of Transport claims that it is“aware of the problems”， but does not regard it as a high-priority issue... 应是相关原因，即交通部承认该问题已引起注意，但并不认为它是头等重要的问题。由此可见，A项内容与原文意思相符，因此是正确答案。[解题关键] 1)理清上下文句义间的内在逻辑关系；2)掌握同义词转换，如A项中 of great significance与原文high-priority意思相当。
