conjunction
军队英文连词是一种虚词, 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(coordinating conjunctions)和从属连词(subordinating conjunctions)。
并列连词用来连接平行的词、词组和分句。如:and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both…and, not only…but also, either…or, neither…nor, (and) then等。
上述并列连词又可分为: 一般连词(simple conjunction) , 关联连词(correlative conjunction)
coordinating conjunct(并列连词)
, or, not only… but also, as well as等表示并列
She plays (both) the piano and the guitar. = If you make up your mind, you'll get the chance.
Make up your mind, and you'll get the chance.
There is no air or water in the moon. =There is no air and no water on the moon.
She plays not only the piano but (also) the guitar.
Neither you nor he is to blame.
注意:
(1) 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。如:Not only does he like reading stories, but also he can even write some.
(2)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。请选择:
---I don‘t like chicken ___ fish.
---I don’t like chicken, ___ I like fish very much.
A. and; and B. and; but
C. or; but D. or;and
改错:
We will die without air and water.
We can't live without air or water.

4.表原因
for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。
so, therefore
eg. He hurt his leg, so he couldn‘t play in the game.

引导名词性从句的从属连词
引导定语从句的从属连词
