1、 高一英语备课组预习学案（4）预习目标：掌握名词性从句的用法.预习自测：在复合句中起名词作用的从句叫名词性从句(Noun Clauses)。名词性从句的功能相当于名词或名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。一、主语从句(划出句子中的名词性从句 )1 That he will succeed is certain.2 Whether he will go there is not known.3 What he said is not true.4 Where he hi
2、d the money is to be found out .5 Whoever comes is welcome.6 How we can help the twins will be discussed at the meeting. 7 When theyll start the project has not been decided yet.为避免主语冗长,句子头重脚轻,经常用 it 作形式主语,主语从句放在后面作真正的主语。1.

3、re.3. It has not been decided yet when theyll start the project.常见句型：Its likely / possible / important / necessary / clear that 很可能/重要的是/ 必要的是/很清楚Its said / reported that 据说/ 据报道It seems / appears / happens that 似乎/好像/ 碰巧.Its been announced / declared that已经通知/ 宣布Its no wonder that 并不奇怪/无疑Its a pity
