will he come today这句对吗?可不可以用is或者does换掉will? he is come 用he will come back行不行? Does he need a haircut?He is not sure.变复合句 He will come tomo 连词成句come,the,will,problem,he,is,whether 为啥用When does he come ,而不是 when will he come come,do,think,I,will,today,not,he.连词成句 That he will come is certain. That she will come is almost certain.可不可以改成She will come tha He will come two weeks later 对吗,为什么 It does not matter whether he will come?这句话中的whether可以用if代替吗 I'm sure he will come tomorrow.(同义句）He is ______ ______ ____ 1,He will come here tomorrow if he can.(同义句)He will come her
