Question

It was in the lab_________was taken charge of by Johnson_________they did the experiment.

A．where; which

B．which; that

C．which; which

D．that; which

Answer 1

B

試題分析：第一空是which引導(dǎo)的定語(yǔ)從句，先行詞是lab，which在定語(yǔ)從句中主語(yǔ)。第二空是that，是強(qiáng)調(diào)句型里的that。這是強(qiáng)調(diào)句型其結(jié)構(gòu)是It was+被強(qiáng)調(diào)部分+ that+其他，判斷強(qiáng)調(diào)句型的方法是把It was that去掉整個(gè)句子不缺成分，是成立的。
點(diǎn)評(píng)：本題難度適中。強(qiáng)調(diào)句型是高中階段的重難點(diǎn)之一，它的考查往往與定語(yǔ)從句放在一起，而是句子更加復(fù)雜，需要考生有分析理解句子結(jié)構(gòu)的能力。
即學(xué)即練：It was not until midnight______they reached the camp site.
A. that    B.when   C.while   D. as
解析：A。該題強(qiáng)干擾項(xiàng)是B，考生容易因強(qiáng)調(diào)時(shí)間狀語(yǔ)until midnight而誤選。
