题目内容
9．-Are you going to help John with his Chinese this evening？-No．He to England．He will be back next month．（ ）
| A． | returned | B． | has returned | C． | returns | D． | will return |
分析 --你今晚将要去帮助约翰学习汉语吗？
--不，他已经返回英格兰了，他下一个月才回来．
解答 答案：B．
现在完成时的构成：have/has+过去分词，表示过去发生的动作对现在造成的影响或结果或表示过去的动作或状态持续到现在．根据"He will be back next month．"他下一个月才回来，又根据"He to England．"可知他已经返回英格兰了，造成的结果是他不在这里，我不去帮他学汉语，所以要用现在完成时，故选B．
点评 首先要掌握现在完成时的构成以及用法，然后结合具体的题目，就可以确定正确答案．
