I have nothing to do but read 这里的read是原型还是过去式,but后加什么?能加过去式吗 Nothing else but后加doing还是to do have been后加动词原型还是过去式谢谢了, I was + 后的动词如何变化,加原型还是过去式 you've后加动词原型还是加动词过去式 单词加es的过去式等于原型的过去式吗?如does的过去式=do的过去式? have to加动词的过去式,had to加什么? enjoy nothing but + to read/reading 请问read的过去式read 读音有什么不同吗 I have said n times.but you read nothing.的中文意思是什么 关于"I have nothing to do but..."句子的问题 ……but to do sth,but后加to do 是不是只限用于I have no choice but to do
