关键使用提醒

1.tolerate 是及物动词：后面必须接宾语，不能说 “He tolerated.”，正确表达是 “He tolerated the delay.”。

2.接动词时要注意：tolerate 后面必须接动名词（doing），不能接动词原形，比如 “忍受熬夜” 是 tolerate staying up late，不是 tolerate stay up late。

3.同源词联动记忆：tolerate（动词，容忍）→ tolerance（名词，宽容）→ tolerant（形容词，宽容的），写作时可灵活转换。

比如 “我们应该对他人宽容” 可以说 “We should be tolerant of others.” 或 “We should show tolerance to others.”。
