given位于句首需倒装【二】

2 . 答案C 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do, 而不能说 Weren&#;t I to do

3 . 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，英语语法《虚拟条件句的倒装》。

4 . 如果我是你，就会去找他。

5 . Had you come earlier, you would have met him
