We need some information for him.
We need some information to him.
这在句意和组成成分上有不同吗？
1. We need some information for him.
这个句子可以说。譬如，大家研究团队由他负责写作论文或报告，大家需要一些资料提供给他：for him = for his report。这里，for him 作定语。
2. We need some information to him.
这个句子有问题，过于省略了，to 的意思非常不清楚。假如改一下就能了：
We need some information to be given to him.
这里，to be givento him 也是作定语，修饰some information。（看作宾补也可）
