98、连词
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。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等等。
99、not only…but (also), as well as不但…而且)
She plays not only the piano, 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 reading stories, but also he can even write some.
but表示转折,while表示对比。
not 和but 后面的用词要遵循一致原则。
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。
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 couldn't play in the game.
although… yet…,但although不与 but连用。 |
