4、 Henry solved the problem.,1.引导表语从句的连接词一般不省略。 .,Our purpose is that he can realize his faults.,2.表语从句表示“是否” 只用“whether” 而不用“if”,The question is whether it is worth doing.,3.如果句子的主语是suggestion, advice. order等名词时,后面引导的表语从句用should+动词原形,should可省略.,他建议我们立刻完成工作。 He suggests that we (should) finish the work at once.

5、 come here.,1.that在宾语从句中不充当任何成分，在口语或非正式的文体中常常被省去。,2. what不可省,有意义,充当成分.,I dont know what he likes.,3.如果主句中有形容词或名词作宾语补足语时，一般用it来作形式宾语，把从句放在宾补后面。,We think it our duty that we should help others.,I find it impossible that he should finish the work in two days.,think + it + adj,+ to do sth. find + it + adj, + to do sth. make + it + adj, + to sth.

Word came that our team won the gam

7、e.,不同之处,1.作用不同：同位语从句用来进一步说明前面名词的内容；定语从句用来修饰,限定前面的名词。,e.g. The news that our team has won the final match is encouraging. （从句说明“消息”的内容：我们队取得了决赛胜利。） The news that you told us is really encouraging. （从句对“消息”加以限定：是你告诉我们的，而非来自其他渠道。但消息是何内容却不得而知。）,2、引导从句的关联词that的功能不同：that引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句的that是关系代词，既指代先行词又须在从句中充当成分。,Dad made a promise that he would buy me CD player if I passed the English test. （that 不充当任何成分）,Dad made a promise that excited all his children. （that指代promise，又在从句中充当主语。）,3.引导

This is the place where the accident happened.,Practice,His proposal that we go there on foot is acceptable. 2. Many teachers

9、hold the view that teenagers should not spend too much time online. 3. He made an excuse that his car broke down on the way. 4.The first request that he made was to ask for freedom. 5.
