核心问题
These fish provide the main food for whales.
上句中的provide...for与provide...with有无区别？
词典解答
provide for 与 provide with 虽然都作“给提供”解,但它们的用法是不同的。前者用于 provide sth. for sb. or sth. 结构(即 for 表示“向谁提供”),而后者用于 provide sb. with sth. or sb. 结构(即 with 表示所提供的物或人)。请对比下列实例:
-
It is the duty of the government to provide homes for old people. 给老年人提供住房是政府的职责。
-
He provided the wine for the meal. 他为这顿饭提供了酒。
-
They provided him with money and clothes. 他们给他提供了钱和衣服。
-
His firm provides him with a car. 他的公司给他提供了一辆汽车。
