题目

用适当的疑问代词和关系代词填空
1：______ is your car?---The red one in front of the tree.（不知道该用which还是where,感觉两个都行昂）
2：The necklace ______ she is wearing is beautiful.（我觉得应该是填with或what）
3：Do you know the person _______ lost his bike?（不知道该用who还是whom丫= =+ 传说中两难的境地）
4：Most people _______ live in less developed countries are quite poor.（感觉应该填whom,
By the way：讲下who 和whom的区别）

答案

1.which
2.that或不填
3.who
4.who
who：主语
whom：宾语
现在一般who也可用做宾语
但whom绝不可以替代who
就如第三题和第四题似的
相信我嘛!...嘿嘿..
