would be与 may be的区别和用法 最好有些例句

在may be中,may是情态动词,be是动词原形,两者构成完整的谓语形式,与主语形成系表结构,意为“也许是、可能是”.
I can’t find my watch.It may be in your pocket.
我找不到我的手表了,它可能在你的口袋里.
He may be a soldier.他可能是军人.
would be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.
总的来说没什么区别...
