wait for与expect的区别
两者均含有“等”之意，但是有区别：wait for (等候)通常指在一个地方呆着，不采取任何行动，一直等到某事发生，它主要强调时间的流逝且含有耽误之意，有时暗示某人来得太晚或某事发生得太迟等；而 expect(期待，预料)则指某事(可指好或不好的事)很可能会发生或到来，不强调时间的迟早，只说明一种心情。比较：
他在校门口等他母亲。
误：He was expecting his mother at the school gate.
正：He was waiting for his mother at the school gate.
我们在等乔治的来信。
误：We are waiting for a letter from George.
正：We are expecting [looking forward to] a letter from Goerge.
那么我 10 点整等你。
误：Then I’ll wait for you at exactly ten o’clock.
正：Then I’ll expect you at exactly ten o’clock.
