It is no longer _ it was 20 years ago

2、, _ it was so poorly equipped. （05安徽卷） A. what; when B. that; which C. what; which D. which; that A A前句考查的是 that 与 what 的区别。that 在名词性从句中不充当任何成分，而 what 可充当名词性的成分。前句的表语从句中还缺少表语，故只能用 what。后句是定语从句，修饰 20 years ago，所以须用 when。问题问题2：1) What the doctors really doubt is _my mother will recover from the seriou

5、oever 与 no matter who; whatever 与 no matter what 等的区别。wh-ever 既可引导名词性从句也可引导状语从句，而 no matter wh- 只能引导状语从句。问题问题4：1) I was surprised by her words, which made me recognize _ silly mistakes I had made. （05湖南卷） A. what B. that C. how D. which 2) Parents are taught to understand _ important education is to

9、es our village look like B. what our village looks like C. how does our village look like D. how our village looks like D DB B名词性从句中都用陈述语序，不用倒装语序。题1中的干扰项是B，对想要知道的人提问或应答都用 it 而不用人称代词 he, I , you 等。题2只要注意是介词宾语就行了。4. 名词性从句中的虚拟语气名词性从句中的虚拟语气 A、宾语从句中的虚拟语气、宾语从句中的虚拟语气在动词 suggest, order, demand, request, des
