高中英语 前有do后无to是在任何句子中都适用吗?比如The only thing that he can do is 我觉得这是错误句 应该是 The only thing that we can do is to the only thing that we can do is to give you some advice.这个句 the only thing that you should do is to try your best.语法有问题么 英语翻译The man who can only do one thing that is eat is a fool. 英语语法the thing that we need to do is to keep clam.这个句子是正确的吗?我 The only thing that I can do is give you some money.为什么可以省略t Maybe this is the only thing that i can do now啥意思? the only thing you can do is pay the fee to recover the serv I think the only thing I can do is hold you tight.is后面加to吗 为 The only thing I can do is wish you happy the that be only will do to thing now这些组成句子
