7. These trousers are dirty and wet — I’ll change into my _____.

A. another                                                B. trousers

C. others                                                  D. other

【陷阱】容易误选A、B。

【分析】最佳答案为C。是从语法上看，another 后通常接单数名词，而不接trousers 这样的复数名词（若用 another pair 则可以）；也不能选 trousers 是因为填它句子意思不通。最佳答案应选C，others 相当于 other trousers，其中的 other 与前面的 these 相对照。

8. Her lecture was hard to follow because she kept jumping from one subject to _____.

A. other                                                   B. the other

C. the others                                             D. another

【陷阱】容易误选B。选择依据可能是one … the other …这一常用结构。

【分析】最佳答案为D。使用one … the other … 时，我们通常是针对两者而言的，即指“两者中的一个……，另一个……”；如果所谈论的情况不是针对两者而言的，而是针对多者而言的，那么我们就不宜在 one 后使用 the other，而考虑用 another。又如(答案均选D，即选 another)：

(1) Those cakes look delicious. Could I have _____ one?

A. other                                                   B. the other

C. the others                                             D. another

(2) I have many such novels. I’ll bring _____ tomorrow.

A. other                                                   B. the other

C. the others                                             D. another

(3) Saying is one thing and doing is _____.

A. other                                                   B. the other

C. the others                                             D. another

比较以下各例：

(1) Shut ____ eye, Jim.

A. another                                                B. some other

C. other                                                    D. the other

答案选D，因为人的眼睛只有两只，故用 one … the other … 结构。

(2) It’s sometimes hard to tell one twin from _____.

A. another                                                B. some other

C. other                                                    D. the other

答案选D，twin 意为“孪生子之一”、“双胞胎之一”，即指两者之一，故用 one … the other … 这一结构。

9. There are four bedrooms, ______ with its own bathroom.

A. all                                                       B. each

C. every                                                   D. either

此题容易误选A，认为既然前面出现了 four bedrooms，故填 all 与之对应。其实，此题的最佳答案应为B，原因是空格后的隐藏信息 its，它表示空格处应填一个单数代词，但是不能选C，因为 every 不能这样单独使用。

10. “It’s said that he is a wise leader.” “Oh, no, he is _____ but a wise leader.”

A. anything                                              B. anyone

C. anybody                                               D. anywhere

【陷阱】容易误选B、C。因为句子主语指人，似乎只有B、C才与之一致。

【分析】其实，正确答案应选A。因为 anything but 是习语，意为“根本不是”或“一点也不”，不仅可用于事物，也可用于人。如：

I’ll do anything but that. 我绝不会干那种事。

The party was anything but a success. 晚会根本不成功。

Her father was anything but a poet. 她父亲根本不是诗人。

Such a man was anything but a hero. 那样的人绝不算英雄。
