【问】 He suggested that a double railway tunnel should be built. (New Concept English，Book 2.L. 64)

一本美国出版的托福教程认为suggest that he should be的用法是错误的。而必须改为suggest that he be。这样看来，上面的句子是错误的了。

【答】 美国出版的Barron’s TOEFL一书确实持有这种观点。但是，这是独尊美国英语、排斥英国英语的做法。事实上，suggest(insist，request，require)that he should be的用法在英国是用得非常普遍的。而且美国作家有时也采用这种用法(例1)：

1. Lester suggested to Jennie that they should go for a drive. (Dreiser)

莱斯特向珍妮建议他们开车出去兜兜。

2. He suggested that this state should be known as the “radiant”.

他建议把这种状态称为“辐射”状态。

3. Carol suggested that I should have another apple. (CGEL)

卡罗尔建议我再吃一个苹果。
