grammar (语法：名词性从句之宾语从句和表语从句)系统记忆：1 概念：在复合句中做宾语的从句叫宾语从句； 在联系动词后面做表语的从句叫表语从句。系动词：be / look / seem---2 引导词：1> that 2> if / whether 3> who, whom, whose, what, which, when, where, how, why--- (as if / as though也可引导表语从句) i know what he is worried about. that is what he is worried about. （所---的事或东西） it seems that (as if) it is going to snow.3 注意： 1> 宾语从句的“介宾结构和形容词加宾语” it depends on how well we cooperate. i’m not sure if he will come. // i’m afraid that i’ve made a mistake. 2> 名词性从句都必须用陈述句语序。 3> 是陈述句的引导词，在宾语从句中可省略，在表语从句中不可。 4> it 做形式主语是主语从句，做形式宾语是宾语从句。 he has made it clear that he won’t agree to the plan.加强练习：1 i know nothing about the young lady except ________ she is from beijing.2 she has never satisfied with ___________ she had achieved.3 someone is knocking at the door. please go and see __________ it is.4 i wonder __________ she can come on time or not.5 why not try your luck in the city, bob? that’s __________ the best jobs are.6 choosing a right dictionary depends on ________ you want to use it for.7 the poor young man is ready to accept _________(what / whatever) help he can get.8 he spoke proudly of his part in the game, without mentioning _________ his teammates had done.9 as soon as he comes back, i will tell him ________ you will come and see him.10 elephants have their own way to tell _________ an object is rough or smooth.11 i was surprised by her words, which made me recognize _______ silly mistakes i had make.12 the bus i took was broken on the way. this was ________________(我来晚的原因)13 the problem is __________________________________(我们到哪拿那么多钱).14 can you tell me ___________________________________(如何才能到博物馆).
