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。
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：
-
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。
-
We have a memorial service every year lest we (should) forget our debt to those who died 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。
-
I avoided mentioning the subject lest he be offended. (LEG) 我回避提到这个问题,以免触犯他。
