【问】 Edison kept phosphorus carefully in a bottle lest it

《英语考试题典》(本科生、硕士生专用，P.533)只给出唯一的一个答案should burn，但我认为还应给出另一个答案：burn。不知您是否同意我的看法。

【答】 同意你的看法。在英国英语中一般采用lest he should do这种格式，在极正式的场合则采用lest he do这种格式。在美国英语中较为流行的，是后一种格式。我们在出题时绝不应忽略这一点。请看下面的实例：

1. The President must reject this proposal，lest it cause strife and violence. (CGEL)

总统必须拒绝此项提议，以免发生争斗和暴力。

2. The animals must be destroyed lest the disease spread.

必须把这些动物消灭掉，以防此病的蔓延。

3. Be careful lest you fall.(《远东英汉大词典》)

小心点，别跌倒。

4. We have a memorial service every year lest we(should) forget our debt to those whodied in battle. (LEG)

我们每年举行一次悼念会，以不忘我们对阵亡战士的缅怀。

5. I avoided mentioning the subject lest he be of fended.(LEG)

我回避提到这个问题，以免触犯他。
