【问】 一九八一年攻读硕士学位研究生英语考试试题第1.14题：

The electric shaver________ before it can be used.

A. needs repairing B. requires to be repaired C. should in repair D. has to be repairableE. must repair

标准答案规定选A。但是，我认为选B也是正确的，不知您以为然否?

【答】 同意你的说法。A. J. Herbert 在The Structure of Technical English (Longmans，1965.

P. 42)一书中认为，need repairing，need to be repaired，require repairing，require to be repaired是平行结构：

Thed bearings to be lubricated.

轴承需要润滑。

Radiation is the most efficient form of transmission for heat which requires to be transmittedin all direction.(P. 43)

对于需要在所有方向上的传热来说，辐射是最有效的传热方式。

权威性的英语著作A Comprehensive Grammar of the English Language也作了同样的论述。该书在列举了下面的例句之后，指出require与need具有相同的用法(第16.39节)：

That door needs.

那扇门需要油漆一下。
