you should do it yourself.这个句子如果加个by蛮好理解,这里没有,请问反身代词也可以做状语吗? maybe you,should do IT by yourself 什么意思? 句子中什么动词后出现反身代词,要在反身代词前加by You should look at it yourself这句话yourself 前为什么不加by 反身代词做主语,可以吗 反身代词可以做主语吗? do it by yourself 写做 do it yourself 为什么? No one can help you but yourself.请问这里的but yourself在这里做什么状语? 听英语老师讲：My mother said,"you should do it by yourself".又有听到He 定语从句和状语从句自己本打算写一个状语从句,可写完以后发现好像理解成时间状语从句也可以,句子如下：you should You 'd better do it yourself 的yourself前不加by吗? 英译汉 do you think you can do it by yourself?
