B．in case

C．so that

D．but

Answer 1

B

解析試題分析：句意:老師又解釋了一次，以防學(xué)生們在做實(shí)驗(yàn)時(shí)有困難。Although盡管；in case萬一；so that以便；but但是。根據(jù)句意故選B。
考點(diǎn)：考查連詞的用法。
點(diǎn)評(píng)：本題難度適中。判斷從句中用哪個(gè)連詞，需用記住連詞的用法，在句中的作用，連詞也是高考的熱點(diǎn)，需要考生平時(shí)多練習(xí)。需要考生會(huì)分析句子成分理解句意。
即學(xué)即練：—Why were you absent yesterday?
—I caught a cold,___________I had been walking around in the rain. A.but       B.so       C.and       D.for
解析：D�？疾楸硎揪売傻倪B詞。for在這里表示補(bǔ)充原因，因此選D。
