请问下面几个英语造句对不对
1.Had I got up earlier,I wouldn't be punished to sing
2.If I weren't to sing(shouldn't sing at class),I could even do anything
3.If I knew I had to sing at class,I would have pretended(been pretending) to be ill at home
括号里面的也可以吗？

答案

第一句：I wouldn't have been punished to sing .（对过去的事情虚拟语气要用完成时呀!wouldn't 用在对现在时的虚拟上面哦）
第二句我不太懂你想表达什么,你是想说我除了唱歌什么也做不了么?如果是的话最好用I couldn't do any ting except singing in class.（这句话是说一个实事,为什么你要用虚拟语气呢?）
第三句：If I had known that I had to sing in class,I would have pretended to be ill at home.（括号里面这个一般没有这么说的,挺奇怪的,感觉意思变成了：我会一直假装生病,但是你开始应该是没有跟老师说你病了的吧~所以从何而来你一直假装自己病了呢,是吧?）
