Question

Last night I was watching some news about the American financial crises(金融危機) on TV _______ the power went off.

A．while

B．as

C．when

D．during

Answer 1

C

試題分析：句意：昨天晚上我正看著電視上播出美國金融危機的事情這時突然停電了。空格前后是句子，所以這里缺少連詞，故排除D；表示正在做某事突然發生另一件事，只有when有這種用法。
點評：本題難度適中。連詞是近幾年高考的熱點，不僅在單選，完形和短文改錯中都是常考的知識點，需要考生記住每一個連詞的用法，意義及區別。
即學即練：_______ the wage of the job was low, there were few applicants for it.
A. While               B. As           C. When            D. During
解析：B。句意：作為一名初出茅廬的記者，他要了解報界生涯的內幕。
