would be 的用法?
我经常看到一些文章中用这个词,语法,语态各是什么?
最好举例子说说~
表示对将来的假想
句型:条件从句 主句
一般过去时 should+ 动词原形
were+ 不定式 would + 动词原形
should+ 动词原形
If you succeeded,everything would be all right.
If you should succeed,everything would be all right.
If you were to succeed,everything would be all right.
虚拟条件句的从句部分如果含有were,should,或had,可将if省略,再把were,should或had 移到从句句首,实行倒装.
Were they here now,they could help us.
=If they were here now,they could help us.
Had you come earlier,you would have met him
=If you had come earlier,you would have met him.
Should it rain,the crops would be saved.
=Were it to rain,the crops would be saved.
注意:
在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was,即在从句中be用were代替.
If I were you,I would go to look for him.
如果我是你,就会去找他.
If he were here,everything would be all right.
如果他在这儿,一切都会好的.
一般还是用虚拟语气比较多.楼主如果有兴趣可以在百度百科查下虚拟语气.
