Hesuddenlyfellill,______preventedhimfromattendinghisfriend’swedding.A.wh

He suddenly fell ill, ______ prevented him from attending his friend’s wedding.A.whyB.whatC.that D.which

D解析试题分析：句意:他突然生病了，这阻止他不能参加朋友的婚礼。这是非限制性定语从句，that不能引导；what不能引导定语从句；why不能在定语从句中作主语，这里先行词是逗号前的句子，which在从句中做主语，故选D。考点：考查非限制性定语从句的用法。点评：本题难度适中。非限制性定语从句是高中的重要的语法项目，在句中所用的关系有限制，提醒考生牢记它们的用法及意义。即学即练：—Alice told me you called yesterday.—Yes, I had a problem with Jane, ______ I thought you could help me with, but you were not in.A. who B. whom C. that D. which解析：D。考查定语从句。第二句句意为：是的，我与珍妮有点问题，我想你能帮我处理，但是你不在。which在定语从句中作with的宾语。
