2、谓语说明主语所发出的动作或具有的特征和状态。

4、除少数句子(如祈使句和感慨句等)外，一句话必须同时具有主语和谓语所表达的意思才能完整。
主语是针对谓语而言的，是一句话的主题，谓语用来说明主语的情况，为主语提供信息。

在正常情况下，英语的主语和谓语的位置与汉语一致，也就是说主语在前，谓语紧跟其后。

状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。
其位置一般放在句末，但也可放在句首或句中，修饰动词、形容词、副词等.7、补语的作用对象是主语和宾语,具有鲜明的定语性描写或限制性功能,在句法上是不可或缺的。
补语是起补充说明作用的成份。
最常见的是宾语补足语。
名词、动名词、形容词、副词、不定式、现在分词、过去分词都可以在句子中作宾补。
8、表语是用来说明主语的性质,身份,特征和状态。
表语须和系动词一起构成句子的复合谓语。
表语一般放在系动词之后。
表语可以由名词,形容词或起名词和形容词作用的词和短语担任。
9、同位语当两个指同一事物的句子成分放在同等位置时，一个句子成分可被用来说明或解释另一个句子成分，前者就叫做后者的同位语.这两个句子成分多由名词(代词)担任，同位语通常皆放在其说明的名词(代词)之后。

2020年9月大学生英语四六级必备资料——考试七种重点语法
2020年9月大学生英语四六级必备资料——考试七种重点语法2020年9月大学生英语46级必备资料——考试7种重点语法1.英语46级考试中虚拟语气。
强调说话人的主观欲望和假想情况。
考生应侧重温习能引发虚拟语气的某些介词、介词短语和连词(如lest,incase,otherwise 等);1部份表示建议、主张、命令、紧要等概念的词语，由于本身隐含说话人的主观欲望，其后的主语从句、宾语从句、同位语从句常常采取should+动词原形;虚拟倒装句;在wouldrather,wish,asif,itstimethat等句型中使用适当情势表达主观欲望;混合虚拟句。
2.英语46级考试中主谓1致。
这类考题灵活性大，需要根据实际情况判断谓语动词的单复数情势。
1部份具有生命意义的集合名词做主语时谓语动词多采取复数情势，如people,poultry,militia等;用and连接的成份表单1概念时谓语动词用单数;就近原则：主语中含有某些连词(如aswellas,besides,inadditionto等)时，谓语动词的数同第1个主语保持1致。
3.英语46级考试中倒装结构。
表示强调或突出，分为全部倒装和部份倒装。
那些否定词(组)、介词短语能引发倒装句，部份倒装和全部倒装有和区分，as 在倒装结构中的用法及意义等等，都是考生应当重视的地方。
4.非谓语动词。
这是辞汇与结构考试中语法部份的重中之重，解题时可以从3个方面入手：①根据非谓语动词同其所修饰的名词或逻辑主语的1致关系，肯定使用主动语态或被动语态，然后斟酌采取现在分词、现在分词被动式或过去分词;②非谓语动词同主句谓语动词动作产生的前后关系。
动作正在进行的用现在分词进行式，同时产生或不分前后产生的用现在现在分词1般式或过去分词;在主句谓语动词之前产生的用现在分词完成式、不定式完成式;产生在主句谓语动词以后的多用不定式1般式;③表状态多用分词，表目的多用不定式。
5.英语46级考试中独立主格题。

1.Has your TV set been repaired?你的电视机修了吗?2.Was the kite broken?风筝破了吗?3.Has the work been done?工作结束了吗?被动语态的否定式是在助动词后面加 not.1.The letter has not been sent out.信还没有发出去。
