初中英语语法归纳(连词)

初中英语语法归纳：连词初中英语学习最难的是语法，因为英语的语法跟汉语的语法有很大的不同。

初中英语连词有很多种。

下面为大家讲解一下初中英语连词的用法。

连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。

连词主要可分为两类：并列连词和从属连词。

第一类表示并列关系的连词并列连词：并列连词用来连接平行的词、词组和分句。

1）and 和判断改错：（错）They sat dow n and talk about someth ing.（错）They started to dance and sang.（错）I saw two men sitt ing beh ind and whisper there.（对）They sat dow n and talked about someth ing.（对）They started to dance and sing.（对）1 saw two men sitting behind and whispering there.解析：第一句：and连接两个并列的谓语，所以talk 应改为talked 。

第二句：and连接两个并列的动词不定式，第二个不定式往往省略to，因此sang应改为si ng 。

第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因此whisper 应改为whispering 。

注意：1. and 还可以和祈使句或名词词组连用表示条件。

（or也有此用法）Make up your mind, and you'll get the cha nee.=If you make up your mind, you'll get the cha nee.One more effort, and you'll succeed.=If you make one more effort, you'll succeed2, A and B 当表示整体或者指同一人时谓语动词用单数，当and连接的单数名词前分别有each，every，many等词修饰时，谓语也用单数。

bread and butter a knife and forkThe mother and teacher is very strict with her son.No teacher and no stude nt is allowed to smoke in class.3. and连接的是两个相同意思的词，表示“渐渐”，或加强语气Read it aga in and aga in2) both…and 两者都She plays (both) the pia no and the guitar.3) neither…nor意思为”既不........ 也不 ... "谓语动词采用就近原则，与nor后的词保持一致。

Neither you nor he is to blame.4) not only …but (also) 不但.............. 而且 ..........She plays not only the pia no, but (also) the guitar.注意：not only…but also关联两个分句时，一个分句因有否定词not而必须倒装。

Not only does he like readi ng stories, but also he can even write some.5) as well as 以及，也，与• ••同样The teacher, as well as the stude nts, is in terested in the activity.比较and和or1) 并列结构中，or通常用于否定句，and用于肯定句。

2) 但有时and也可用于否定句。

请注意其不同特点：There is no air or water in the moon.There is no air and no water on the moon.在否定中并列结构用or连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

第二类表示选择关系的连词1) or 意思为”或则"。

Which do you prefer, tea, coffee, or juice2) either…or 意思为”或者.......... 或者 .... ”。

注意谓语动词采用就近原则。

Either you or I am right.3) or else/ otherwise 否则Be sile nt, or else you will be kicked out.I am tired, otherwise, I would play.第三类表示转折或对比关系的连词1) but 但是He is rich but un happy.while 然而，表示对比意味Some people love cats, while others hate them.yet 然而She said she would be late, yet she arrived on time.however 然而，可是，不过She does not like him, however, I like him.2) not…but… 意思为”不是 ....... 而是 ... "not和but后面的用词要遵循一致原则。

They were not the bones of an ani mal, but (the bon es) of a huma n being.第四类表因果关系的连词1) for 因为，做并列连词使用时，是在对先行的句子补述原因或者理由，只可以连接句子与句子，通常不置于句首。

He is abse nt today, for he is ill.2) so, therefore 因此He hurt his leg, so he could n't play in the game.I thi nk, therefore I am3) then 那么，因而Hide behind the wall, then they won ' t see you.注意：a. 两个并列连词不能连用，但therefore, then, yet. 可以和并列连词连用。

You can watch TV, and or you can go to bed.He hurt his leg, and so / and therefore he could n't play in the game.b. although …yet …，但although 不与but 连用。

(错) Although he was weak, but he tried his best to do the work..(对) Although he was weak, yet he tried his best to do the work.从属连词从属连词不同与并列连词，只能用来引导从句，而不能引导词或者词组。

从属连词一般可以引导名词性从句和状语从句。
