一、初中英语名词性从句
1.________ the weather will not clear up until next week is bad news for us.
A. As B. If C. Whether D. That
【答案】 D
【解析】【分析】考查主语从句。句意:直到下周天气才放晴,这对我们来说是坏消息。此处是that引导的主语从句,that无实义,只其引导作用,故答案为D。
【点评】主语从句属于名词性从句,在名词性从句中,that无实义,只起连接作用,不做句子成分;if/whether起连接作用,不做句子成分,有实义“是否”。做题时注意看从句是否少成分。

A. what that B. which C. that D. that what
【答案】 D
【解析】【分析】句意:有人指出,驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句,it作形式主语,真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.,主语从句中又有一个主语从句,且此主语从句中缺少主语,所以用what引导。故选D。
【点评】考查名词性从句,本题涉及what引导的主语从句。

4.________ his failure lies is expected ________ clear to us.
A. What… to make B. How… made C. Where… to be made D. Why… making
【答案】C
【解析】【分析】句意:他的失败之处有可能被我们弄清楚。分析句子可知,主语从句中的lie为不及物动词,所以主句中缺少状语,因此填where。expect sth.to do.固定短语,“期望某事发生”,sth. be expected to do.意为”某事有可能发生“。make sth. clear to sb为固定搭配,意为“向某人阐明某事,使某人弄清某事”。本句中make的宾语是where his failure lies是被弄清楚,要用动词不定式的被动形式。因此选C。

【解析】【分析】句意:——是什么让她对她自己感到羞愧?——是她获得了她班上的最低分让她惭愧。A中的what是句子的主语,但是because引导的从句不作主语,是原因状语从句,故排除;B的第一空是错误形式,故排除;C、D两项的第一个选项是一样的,说明第一个题干是一个强调句型,特殊疑问句下的强调句型,有what引导;第二个空是对what的回答,因为what是上一句的主语,That she got the lowest mark in her class是从句,可以作主语;而D项的get是动词原形,不能作主语,故答案为C。
