常见错误

❌ 错误:I request you helping me with this task.
✓ 正确:I request that you help me with this task. / I request you to help me with this task.

错误:request 后不能直接接“宾语 + 动词-ing”。正确:应用 request that + 从句(动词用原形)或 request + 宾语 + to do 结构。

❌ 错误:He made a request of a promotion.
✓ 正确:He made a request for a promotion.

错误:介词 of 在此不适用。正确:表示请求内容时,名词 request 常与 for 连用,如 a request for something。
