(4)宾语从句的否定转移。将think，believe，suppose，expect，fancy，imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。如：

①I don’t think I know you．我想我并不认识你。

(5) 在于表示命令、建议、要求等一类词后面的宾语从句谓语用 should +动词原形（insist, order, command, suggest, advise, propose, require, request, demand, desire ）

特别提示

(1)as/as if/as though引导的表语从句常跟在特定动词后面，

如seem，appear，look，taste，sound，feel等。常用虚拟形式，即表示与现

在事实相反，用过去式；与过去事实相反用过去完成式 (had done).如：

①It sounds as if someone was knocking at the door．听上去好像有人在敲门。

②He speaks/ spoke as if he had known about it

(2)当主句的主语是reason时，表语从句一般由that引导，这种用法常见于句型The reason why…is that…。如：The reason why he came late was that he got up late．他来得晚是因为起床晚了。

考点3 同位语从句

同位语从句在句子中作某一名词的同位语，一般位于该名词之后，说明该名词的具体内容。这些名词常见的有idea，fact，news，hope，belief，thought，doubt，promise，suggestion，order等。

1．通常用连词that引导同位语从句，that无词义，也不作句子成分，但不能省略。注意从句用陈述句语序。如：

①They expressed the hope that we would go and visit Shanghai again．他们表示希望我们再去访问上海。

②I have no idea that she quit her present job．我不知道她辞掉了现在的工作。

③Give me your promise that you will come to our party this evening．答应我，你今天晚上会来参加我们的聚会。

②I have no idea why he was excited at that time．我不知道当时他激动的原因。

1. 在suggestion / proposal / order / plan / advice / idea / request 等名词后的表语和同位语从句中要用“should＋动词原形”should可以省略．

My idea is that we (should ) think it over before accepting it.

考点4 名词性从句需要注意的事项

1．that的用法。在主语从句、表语从句和同位语从句中that一般不能够省略；在宾语从句中有时可以省略，一般需要注意下面两点：

(1)当that从句作介词宾语时，that不能省略。如：They share little in common except that they are from the same country．除了来自同一个国家之外，他们几乎没有共同点。

(2)当主句谓语动词后接两个或两个以上的宾语从句时，可以省略第一个that，其他的不省略。如：

I believe(that)you’ve done your best and that things will improve．我相信你已经尽力了，而且情况也会得到改善。

2．that与what的区别。that在从句中不能够充当句子成分，也没有含义；what可以在从句中作主语、表语、宾语或定语，意思是”什么，……的事情”。如：

①The hope that he may recover is not gone yet．他会康复的希望没有消失。(that不充当成分，也无含义)

②What he said proved to be true．他所说的话证明是正确的。(what作said的宾语，可以翻译为“……的话”)

3．定语从句与同位语从句的区别。定语从句是从句对其先行词的修饰或限制；而同位语从句是对从句前面的抽象名词作进一步的说明和解释。如：

①The news that our team has won the game was true．我们队赢了那场比赛的消息是真的。(同位语从句，补充说明news到底是一个什么消息)

②The news that he told me yesterday was true．昨天他告诉我的那个消息是真的。(定语从句，news在从句中作told的宾语)

③I made a promise that if anyone set me free 1 would make him very rich．我许诺如果谁让我自由，我就让他非常富有。

(同位语从句，补充说明promise的内容)

④The mother made a promise that pleased all her children．妈妈许下了一个令她的孩子们高兴的诺言。(定语从句，promise在从句中作pleased的主语)

如何学好高中英语语法

我是一个高考的过来人，高考成绩129分，平时大考碰运也考过130+的分数。首先我想请阁下明白一个道理冰冻三尺非一日之寒，所以坚持很重要，英语是一门很看重积累的科目。

虽然我高考已经好多年了，而且今年即将大学毕业，踏入社会。但英语一直没有丢，英语一直是我的排头兵！我对英语的自信还有，我觉得学好英语不难，重要的是你要有恒心，急躁冒进，三天打渔两天晒网都是不行的。在这里我就毛遂自荐一下我的学习方法吧：

首先先你要端正心态，不要急躁，，你做你自己的事，这样才能静下心来学习。要成为英语高手就必须比别人走更多的路，做更多的事。你应该明白一个事实，英语是单词和语法的综合，所以单词和语法都要拿下。

其次，对于单词，有如下几种方法，第一个，是加强记忆的频度，也就是说，早上记了几个，隔几个小时又看一次，总之一天之内，记忆的间隔不要太长，否则你辛苦积累的记忆会随着时间的延长而淡化，第二个，是可以根据自己的理解编顺口溜，比如good morning 是狗摸你…（见笑了）…，第三个，最重要的是，记单词的时候，不要忘了阅读，一边记单词，一边看文章，这样可以把孤立的单词串联起来，记忆的效果会加倍，第四个。我建议你记单词要分门别类记忆，要形成一个意群，比如，重要性用magnitude magnificence ，表示非常，大大地有exceedingly，tremendously，extremely……这样做在你写作时，是十分有好处的，写作时不要尽写一些低级词汇，你要写高级词汇，比如重要性写magnitude，许多写a multitude of 或者handsome。

再次，是语法。学习语法，首先要明白什么是主谓宾定状补，什么是系动词，什么是直接宾语，间接宾语，这些是学习语法的基础，语法是房子，主谓宾定状补等是沙石砖瓦。然后就要多做一些语法专项练习，并在此过程中不断总结，并时时回顾那些了解，那些依然不理解，需要注意的是，那些不理解的一定要花时间弄清楚，否则对自己的不负责将会导致英语语法一知半解的结局！

这对于想成为英语高手的人来说，是十分不利的！（注：本人从开始时不知主谓宾，到熟练掌握语法，把语法书看了不下二十遍，书都翻烂了！莫笑本人愚笨……）

此外，对于完形填空以及阅读理解，那就只能靠平时的练习了，在这个过程中，你要时时总结，纵深对比，千万不要陷入题海战术只做题，不总结的误区当中。在做题的过程中，你把各种体型都总结了一遍，积累了丰富的经验，而且你还提升了自己的阅读速度，一举两得，所以做题是很重要的！

其实，完形填空无非就是单项选择加语境分析，也就是说，做完形填空你的语法要好，而且你要积累比较多的固定搭配，短语，特殊用法等，完形填空的语法还是很重要的！对于阅读，我个人感觉是，纯粹是个人经验积累多少的问题，只有保证一定的练习量，你才能用质的提高！

最后，我建议你，平时读报，或者做题的时候，发现有好的句子好的词汇，你要抄下来，长期下来，你的作文会有提高的，需要说明的是，这个提高过程可能很缓慢，但是最后能收到很好的效果，以前25分的作文我都能保证在21-23这个级别，靠的就是对语法的熟练掌握和积累了许多较高级的词汇，句型，句子。

我个人的理解是，在你的语法达到基本不会出错的程度上，作文便应该以词汇取胜，因为在这个层次上，大家的语法都差不多，没什么变化，唯一有变化的就是你的词汇！给你打个比方吧，很多想到“许多”就用many，但是你别忘了many a ；handsome；massive，innumerable；很多人想到“专家”就写expert，但很少人会想到specialist，很多人在想到“擅长”这词，就写be good at ，却不知还有更高级的表达法：be expert at 或者excel in ……高手和庸才，就体现在这些细微的差别上 ！
