英语名词性从句的六个命题切入点

所谓-ever词，指的就是那些以-ever结尾的连接代词，其中最重要的有三个：whatever, whoever, whichever。从意义上看，whatever表示“无论什么……”，whoever表示“无论谁……”，whichever表示“无论哪个……”；从句法上看，它们在从句中可用作主语和宾语（其中whichever和whatever还可用作定语）。同学们做题时，就可以从意义和句法两个方面入手进行分析。请看以下高考实例：

1. We promise ______ attends the party a chance to have a photo taken with the movie star. (福建卷)

A. who                     B. whom                C. whoever               D. whomever

2. The newcomer went to the library the other day and searched for ______ he could find about Mark Twain. (辽宁卷)

A. wherever             B. however               C. whatever              D. whichever

3. As many as five courses are provided, and you are free to choose ______ suits you best. (陕西卷)

A whatever               B. whichever            C. whenever              D. wherever

解析：第1题选 C。whoever 在此引导宾语从句，相当于 anyone who。句意为：我们承诺，凡是参加晚会的人都有机会与电影明星合影。

第2题选C。由于从句中的 find 缺宾语，所以可排除不能用作宾语的连接副词 A 和 B。whatever 与 whichever 的区别是，前者所暗示的选择范围是不明确的，而后者所暗示的选择范围则是明确的。根据句意，C更符合句意。句意为：那个新来的人前几天去了图书馆，寻找任何他能找到的有关马克·吐温的书。

第3题选B。由于从句缺主语，所以可排除不能用作主语的连接副词 C 和 D。至于A和B，根据句子前面说的As many as five courses are provided 可知，选择范围是明确的，故选 B。句意为：提供了多达五门课程，你可以自由选择最适合你的。
