答案解析:
1.【答案】D。解析:考查定语从句。句意:众所周知,太多的压力会造成疾病。句中已有谓语动词can cause,说明句子前半部分是从句,故而排除It;分析句子结构可知,设空处引导非限制性定语从句位于句首,且从句中缺少主语,所以只能选择关系代词as引导该句子,且as指代后面的too much stress can cause disease部分做主语。故答案选D。
2.【答案】B。解析:考查并列连词。句意:你不要那样做,否则会发生事故的。在这四个并列连词中,只有or含有这样的意思,故选B。
3.【答案】D。解析:考查主语从句。句意:众所周知,知识来源于实践。句子出现两个动词,需要一个连接词,“________ knowledge comes from practice”为从句部分,位于系动词之前,为主语从句,从句不缺成分,句意完整,应填从属连词that,故选D。
4.【答案】B。解析:考查固定搭配。句意:过去,他总是负债累累。但是近几年他通过和当地商人做生意而谋生。in debt欠债,earn one’s living谋生,维持生计。故选B。
