如题所述
由that引导的表语从句如：
The trouble is that he misunderstood me.麻烦的是他误解了我 that是不可以省的
有时,引导表语从句的连词that可以省略
The truth is (that) I didn’t finish my term essay. 事实是我没有写完学期论文。
表语从句中应注意：
1. 连接词that一般不能省略，但当主句中含动词do的某种形式时，that可以省略。如：
What I want to do is (that) I can go up to him and thank him. 我想做的事是走到身边去感谢他。
2. 当句子的主语是：advice, demand, decision, desire, idea, insistence, instruction, order, plan, proposal, recommendation, request, requirement, suggestion, wish等名词时，表语从句须用虚拟语气，即：should +do。如：
My advice is that you should go to apologize to him. 我的建议是你应该去向他道歉。追问

那第一种省略的情况与不省略的区别是什么第二种主句含有do的某种形式懂了
