18、 the trouble with him yesterday?二、从句中的虚拟语气问题1. 主语从句：(1) It is important/ natural/ necessary/ essential/ strange/ that (should) do (2) It is suggested/ advised/ demanded/ ordered/ requested that (should) doe.g. It is important that every student (should) learn a foreign language.

22、th. I don t doubt that he told the truth. The doctor s doubt is whether my mother will recover from the disease soonI have no doubtthat Tom is a talented actor.2. sure -be sure用于肯定句或疑问句时，后接that 引导的名词性从句；用于否定句时，后接 whether 引导的名词性从句。e.g. I m sure that Ive found the answer to this question. Are you sure

23、 that youve found the answer to this question.I m not sure whether Ive found the answer to this question. 3. 主语是 reason 时，表语要用that 引导而不是because ：e.g. The reason why he was late was that he missed the train by one minute this morning. 4. what和 that - that 在从句中不充当成分，不含疑问意义，而what 在从句中充当主语、宾语或表语，且含有疑问意义

What Tom learned in university helps him a lot in his job. =All that Tom learned in university helps him

26、ts them to do. (=anything that he wants them to do)6. This/ That is why和 This/ That is becausee.g. The reason why I came late is that my car broke down on the half way.He came late. Thats because his car broke down.His car broke down on the half way. Thats why he came late. 7. 几个特殊句型之间的转换It is known

Will you please see to it that the children get a hot meal after their swimming?I hate it when they talk with their mouth full of food. 五、同位

30、语从句和定语从句的区分e.g. The idea that one can do the work without thinking is wrong （同位语从句，that在从句中不充当成分，不可省略，从句具体说明idea 的内容）。The idea that you put forward at the meeting is wrong (定语从句， that 代替 idea在从句中做put forward的宾语， that 可以省略 )。The suggestion that we discuss the problem all over again is a good one. The suggestion that he gave at the meeting was a good one. 【名词性从句的解题思路】：高考中考查名词性从句时，经常考查连接词的选用。解题时应先判断从句的类型，然后判断从句是否缺少成分以及意义是否完整，最后根据引导名词性从句的连词的特点确定特定的连接词。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 5 页，共 5 页 - - - - - - - - -
