should do在此表示万一的意思。即if从句发生的可能性不大,但也不是没有,万一发生的话,就...。
如果if 从句用一般现在时,则意味着从句所说的情况是可能发生的。如果发生,就...、
If these biscuits should arrive in a damaged condition,please inform the factory at once.
If these biscuits arrives in a damaged condition,please inform the factory at once.
请问If条件从句用虚拟语气和陈述语气区别是什么?
1.意思一样,语体不同 should arrive是古英语更正式,arrives是现代英语非正式?
2.陈述语气表示从句内容很可能会发生,虚拟语气表示从句内容不太可能发生/未定是事实?
是以上两种情况的一种呢还是都不对,求各位大神指导!
【1】If these biscuits should arrive in a damaged condition,please inform the factory at once.
相当于:Should these biscuits arrive in a damaged condition,please inform the factory at once.
【2】If these biscuits arrives in a damaged condition,please inform the factory at once.
