求解答英语选择题 关于虚拟语气
If only I __ play the guita as well as you.
A would B should C could D might.
为什么不选A\C,只选B?
If your car__any attention during the first 12 months, take it to an authorize dealer.
为什么选should need,而不是would need?

虚拟语气中,如果从句是表示不成立的一个事件,从句中可以用should+动词原形,should可以省略。一般来说,表示建议,坚持,命令等的句子,从句就要用虚拟语气。

这两句话并不是虚拟语气的句子。第一句的if表示“是否”的意思,是宾语从句;第二句中if表示“如果”的意思,是条件状语从句。虚拟语气的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形” 如If I were you, I would go with them。

虚拟条件句中的情态动词只有一个,就是should

这个是个专业基础知识
但是很遗憾
你没得悬赏分

这两个句子都是对将来情况的取反,从句用should+动词原型,或者用were to do 其他形式不可以.
