学习必备欢迎下载（附件：虚拟语气和定语从句that 用法的归纳）虚拟语气（ subjunctive mood）虚拟语气是历年TEM4 语法考点的重点，用于强调怀疑或不可能，动作只存在于讲话人想象中的“假设” ，而不是当作客观事实中的真实事件。因此，当学生看到含有“怀疑/推测 /愿望 /假设”等意味的句子时，就要打起精神，仔细辨别。1．常用“（should）+动词原形”表虚拟语气的结构a. 表示主观判断、推测和表示命令、决定、要求、建议之类的词的相关从句中，可用于：◆宾语从句：He suggested that we (should) stay home. ◆表“命令、决定、要求”等名词的同位语从句He put forward the suggestion that we (should) stay home. ◆上述名词的表语从句His suggestion was that we (should)stay home. ◆主语从句It was suggested that we (should) stay home. 例题：He left orders that nothing__________touched until the police arrive here.
