He says he's staying( at a youth hostel)就划线部分提问 关于I have just和he is just,谢谢!Penny:'I have just arrived in Scotland and I'm staying at a Youth Hostel.'Grandmother:Eh?Penny:He says he's just arrived in Scotland. He says he's staying at a Youth Hostel. You know he's a member of the Y.H. 关于I have just和he is just,Penny:'I have just arrived in Scotland and I'm staying at a Youth Hostel.'Grandmother:Eh?Penny:He says he's just arrived in Scotland.He says he's staying at a Youth Hostel.You know he's a member of the Y.H.A.新概念 1.He says he's just arrived in Scotland.2.He says he's staying at a Youth Hostel.请问第一句话的he's=he has 是现在完成时态 第二句话 he's=he is 是一般现在时态 He says he's just arrived in Scotland.saysHe says he's just arrived in Scotland.says后不加that? He says he's just arrived in Scotland.he's=he has? 是he says还是says he的 He says he's just arrived in Scotland.为什在says后面不加个that he says he is busy 这里的 says 为什么加 s How long is he staying?He's staying ___ a week.A at B for C in D from he says是什么意思 he says soberly He says he needs a book.say已经加s了,为什么need还要加s? he is staying at a youth hostel 对staying后面的提问 i think he will come back soon 变为否定句 he can not write a novel 变为反义疑问句 My cat has drunk all its milk变为一般疑问句 he says he has finished his homework 对says后 he's the man who he says bought these books.这句语法有没有错?
