another还是the other

请看下面的一道题，是考查one…the other还是考查one…another?

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

A. other                        B. the other                        C. the others                        D. another

【分析】此题容易死套搭配 one … the other…而误选B，其实最佳答案为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 are wonderful. 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。
