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：“允许完成练习，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.
