以下是引用LES在2004-5-23 20:03:00的发言:40. In metalwork one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bonding, is effected continuously over a broad surface instead of a series of regularly spaced points with no bonding in between. (A) instead of (B) as opposed to (C) in contrast with (D) rather than at(D) (E) as against being at 想请教大家的是这里 and hence the bonding算是什么用法?插入语?为什么用and连接,却又不影响谓语动词的数?真奇怪!
说说我的想法:
我觉得从逻辑意思上理解,这里想说的是
the contact is effected continuously over......, and hence the bonding is effected continuously over.....
就是说the contact和the bonding都is effected continuously.....于是就二个放在一起,省略了后面那个the bonding后面相同的部分。我不知道这用语法术语怎么说,但我记得在阅读里这种现象好象有看到。
请指教。 |
