A.The weather is fine B.Should the weather be fine

Answer 1

你问的是关于 虚拟语气中if的省略 的问题.
虚拟条件句中有were,had,should时,可把if省略,而把were,had,should
放在主语前,用倒装结构,这种结构主要用于书面语中．
如：
1．Were it necessary,I might resign．＝If it were necessary,I might resign．
2．Had you informed me earlier,I would not have signed the contract．
＝If you had informed me earlier,I would not have signed the contract．
3．Should I have time,I would call on her．＝If I should have time,I would call on her．
4．Should it rain tomorrow,we would have to put off the visit to the Summer Palace．
＝If it should rain tomorrow,we would have to put off the visit to the Summer Palace．
5．Should I meet her,I would tell her．= If I should meet her,I would tell her．
6．Were I in your position ,I would do it better．= If I were in your position,I would do it better．
7．Were he to tell us everything,we could try to solve his problem．
8．There is a real possibility that these animals could be fright ened,should there be a sudden noise．
9．Had they made preparations,they would have succeeded．= If they had made preparations,they would had succeeded．
10．Were I in school again,I would work harder.= If I were in school again,I would work harder．
11．Had you been here earlier,you would have seen him．＝If you had been here earlier,you would have seen him．
12．Were it not for the expense,I would go to Italy．＝If it were not for the expense,I would go to Italy.
你的问题和上面的例题3、4、5一样的,正常语序是 If the weather should be fine ,we would go on a picnic .此外本题if从句是对将来的推测,所以可用should+do 的形式,不知你明白了吗?
