虚拟语气的考点可以归纳如下：
1. (should)+动词原形的情形(已考)
2. if或but for等引导的条件句(已考)
3. wish, if only, it is time…的用法
(should)+动词原形的情形
1．在动词suggest, order, demand, propose, command, request, desire, insist, require, decide, promise, resolve, argue, maintain, determine, recommend, advise, advocate, persuade等表示“命令”、“建议”、“要求”动词后的宾语从句中。
