题目内容

2．-Would you like to go out to play football with me，Sam？
-I'd love to．But I haven't finished my homework _________．（　　）
A．yetB．alreadyC．ever

分析 --萨姆，你愿意出去和我踢足球吗？
--我想去，但是我还没完成我的作业．

解答 答案：A．
yet意思是"已经，还"常用于否定句和疑问句，yet 用于现在完成时作"已经"讲，只用于否定句和疑问句；already意思是"已经"常用于肯定句中；ever意思是"曾经"；根据"I haven't finished my homework"我还没完成我的作业，这是一个否定句，句中用了现在完成时，所以要用yet来填空，综上所述，故选A．

点评 首先要掌握这几个副词的意思，然后结合具体的题目，就可以确定正确答案．
