13.Heis going to stay(stay) here until the end of this month if he is allowed to,isn't he?分析 句意:如果允许的话,他将在这里一直待到这个月末,不是吗?
解答 答案:is going to stay 根据后文isn't he?不是吗?这是一个反义疑问句,后面用否定,前面就用肯定;同时,if作为连词,引导条件状语从句,表示"如果".在复合句中如果主句用将来时,则if引导的状语从句用一般现在时,反之也可.本题中if he is allowed to是一般现在时,故前面主句用将来时is going to stay.
点评 if作为连词,引导条件状语从句,表示"如果"等.在复合句中如果主句用将来时,则if引导的状语从句用一般现在时.
