| 词组 | provide |
| 释义 | 1．下面四句意思相同： We provided them with board and lodging. We provided board and lodging for them. We provided board and lodging to them. We provided them board and lodging. 第三句不及第二句普通。第四句里 provided 有双宾语，是比较新的结构。 2．provide（规定）后面的以 that 引导的从句里用 shall 或 should，不用 will 或 would。例如：The contract provides that only the best materials shall be used.和 The contract provided that only the best materials should be used.有时用虚拟现在式。例如：The contract provides（或provided）that only the best materials be used. 3．provided 用作连接词，原来是 provide（规定）的过去分词，provided...或 provided that...作“规定……”解，也就是“以……作条件”的意思。也有人用 providing 代替 provided，但有人认为不算正当。 provided...或 provided that...可以说等于 if...，通常都用在比较正式的英语里。例如：I will go provided (that) you will go with me. ＝I will go if you will go with me.但并不是一切可以用 if 的场合都可以用 provided 或 provided that 代替它。因为 provided 原来作“规定”解，它所引导的从句该是一种“规定”，而且那“规定”该是那“规定者”所认为该实现的。如 I will go provided(that) you will go 里的 you will go 是“规定”，I 是“规定者”，I 认为那“规定”该实现，就是说 I 认为 you will go 该是事实。I will not go provided (that) you will not go 便不对，该把 provided (that) 改作 if，因为这里的“规定者”I 并不认为那“规定”you will not go 该实现。下面各句里的 if 都不可改作 provided 或 provided that： You may lose your membership if you make the same mistake again. What will happen if they see us? He said he would punish me if I was lazy. Things would have been different if we had taken another course of action. 假使你觉得 provided 难用，你尽可以不用它，在一切可以用 provided 的场合用 if 总是不错的。 |
