1. (2016·江苏)It is often the case ____________anything is possible for those who hang on to hope.
A. why B. what
C. as D. that
【答案】D
【解析】
【详解】考查主语从句。句意:通常对于那些心存希望的人来说一切皆有可能。此句中It为形式主语,that从句为真正的主语。从句的句意和句子结构完整。故D项正确。
【名师点睛】that 引导主语从句:由连词that引导的主语从句,在大多数情况下不放句首,用it 作形式主语来代替它的位置。常见的以it作形式主语的主语从句的句型有三种:
一、It + be +形容词+that从句.
适用于这种句型的常见形容词有:necessary,clear,true,strange,important,wonderful,possible,likely,obvious,surprising等。如:
1. It’s clear that they badly need help。很明显,他们急需援助。
2. It’s possible that we can carry out the project at last. 最终我们有可能实施这个项目。
当表语为 necessary,clear,true,strange, important, wonderful,possible, likely, obvious, surprising, astonishing, etc.等形容词时,谓语动词的形式一般为"should+动词原形"。如:
3. It is necessary that you (should) master the computer. 你很有必要掌握电脑。
4. It is strange that he should have killed himself.真奇怪,他竟然自杀了。
