第五讲名词性从句
从属连词that, whether与if引导的名词性从句
[全析考法]
单句语法填空/单句改错
1.(2018·11月浙江高考)It is possible ________ caffeine may cause birth defects (缺陷) in humans, too.
解析:that 分析句子结构可知,该句是一个主从复合句,it作形式主语,that从句为真正的主语。
2.(2017·天津高考改编)She asked me________ I had returned the books to the library, and I admitted that I hadn't.
解析:whether/if 句意:她问我是否已经把书还给图书馆了,我承认说我还没有还。分析句子结构可知,空格处引导宾语从句,且在从句中不作任何成分,只起连接作用;又根据句意可知此处表示"是否",故用whether或if引导宾语从句。
3.(2016·北京高考改编)The most pleasant thing of the rainy season is________ one can be entirely free from dust.
解析:that 句意:雨季最令人高兴的事情就是人们可以完全远离灰尘。分析句子结构可知,本句包含一个表语从句,且表语从句中句子结构完整,故使用that引导表语从句,that在表语从句中不作句子成分,只起连接作用。
4.(2016·天津高考改编)The manager put forward a suggestion ________ we should have an assistant. There is too much work to do.
解析:that 句意:经理提出了一个建议,我们应该有一个助手。工作太多了。分析句子结构可知,空处引导同位语从句,解释说明suggestion的具体内容,故填that。
5.(2016·江苏高考改编)It is often the case________ anything is possible for those who hang on to hope.
