虚拟语气考点透析
考点一、虚拟语气的基本用法
1.与现在事实相反的虚拟语气，基本结构为：主语+动词的一般过去时（be动词用were）+其他成分+if+ should/would/could...+动词原形+其他成分。例如：
①if it were not for the fact that she ______ sing，i would invite her to the party.
a. couldn’t b. shouldn’t c. can’t d. might not
解析 句意为：如果不是因为她不会唱歌的事实，我会邀请她来参加那次聚会的。that从句为同位语从句，描述的是事实，用陈述语气。正确答案为c。
2.与过去事实相反的虚拟语气，基本结构为：主语+动词的过去完成时+其他成分+if+should/would/could...+have done+其他成分。例如：
if the weather had been better，we could have had a picnic.but it ______ all day.
a.rained b.rains c.has rained d.is raining
