congratulate的宾语有何特点
1. 其宾语通常是人，不是事；要表示因某事而祝贺某人，可用congratulate sb on [upon] sth。如：
我祝贺他取得成功。
正：I congratulate him on his success.
误：I congratulate his success.
2. 其后习惯上不接不定式的复合结构作宾语，即不说congratulate sb to do sth，可改为congratulate sb on doing sth。
He congratulated us on getting married. 他祝贺我们结婚大喜。
3. 有时接反身代词作宾语。如：
You can congratulate yourself on having done a good job. 你的工作干得出色，你应该感到自豪。
