文档介绍：一、非谓语动词
“非谓语动词”可分为动词不定式、动名词和分词。它在句子中的作用很多:除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语)。有些及物动词后面接不带to的不定式作复合宾语。这些动词归纳如下:一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe)。再加上help somebody(to)do something和美国英语look at somebody do somthing。还有“二让”属特殊:get somebody to do something 与keep somebody doing。而有些及物动词后面接动名词(the -ing form)作宾语。这些动词归纳为一句话:Papa C makes friends。这是由如下动词的开头字母组成:permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受)。为了容易记住,也可以编成顺口溜:“允许完成练****建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”。其相对应的动词依次是:permit/allow,finish,practise;
advise/suggest, avoid,risk: consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand。
二、复合句
1、学生最容易混淆的是定语从句与同位语从句的区别。
例如:A、The news that our team has won the match is true. (同位语从句)
B、The news that he told us surprised everybody here. (定语从句)
关键的区别在于连接或关系代词that:有意义的是定语, 无意义的是同位。因为引导定语从句的that在从句中作主语或宾语,而引导同位语从句的that只起到连接词的作用。
2、接着容易混淆的是引导定语从句的关系代词that与 which:that之前是不定(代词)、序数(词)、(形容词)最高级:which之前是介词短语与逗号(非限制性)。
例如:A、All that we have to do is to practise every day.
B、The first lesson that I learned will never be forgotten.
C、I have lost my pen,which I like very much.
D、The house in front of which there is a garden is my home.
三、It的用法
1、It除了代替人和物以外,还可以作形式主语。而真正的主语(不定式、动名词或从句)则放于谓语或表语之后。
例如:It is nor easy to
