　　1.serve vt., vi.

　　(1)帮佣，当仆人，给……干活：

　　Mary served (in) the family as a cook for more than ten years.玛丽在那户人家当了十多年厨师。

　　(2)服务;服役;供职：

　　Have you ever served in the army?你服过兵役吗?

　　She served the firm as a secretary for two years.她在这家公司当过两年秘书。

　　(3)接待(顾客)：

　　The assistant was eager to serve her this time.那个售货员这回接待她的态度非常殷勤。

　　Tom served in a restaurant when he was 18.汤姆18岁时在餐馆当过侍者。

　　2.make与let

　　这两个动词后面都跟不带to的不定式，但意义和用法上有区别。

　　(1)make+名词/代词+不带to的不定式表示"迫使"、"致使"：

　　That beard makes you look much older than you really are.您的胡须使您看上去比您的实际年龄大得多。

　　What made him change his mind?是什么使他改变了主意?

　　She made the assistant bring almost everything in the window.她迫使那位售货员把橱窗里几乎所有的东西都拿了出来。

　　在被动语态中含有上述意义的make后面必须带to:

　　He was made to work fourteen hours a day.他被迫一天工作14小时。

　　He was made to change his mind.他被迫改变了主意。

　　(2)let有两种用法，一是用于祈使句，建议包括说话者在内的人采取某一行动：

　　Let's not waste any more time.我们别再浪费时间了。

　　Let's take a taxi.我们坐出租车吧。

　　其否定形式除Let's not…外也可以用Don't let's…:

　　Don't let's waste any more time.我们别再浪费时间了。

　　这种祈使句中的let相当于助动词。

　　let的第2种用法是表示"允许"，其结构与make相同，即 let+名词/代词+不带to的不定式。如果宾语是us,则不能缩写成let's:

　　Please let us have more time, will you?请多给我们一点时间好吗?

　　I won't let you ride my bicycle.我不让你骑我的自行车。

　　Let him speak.让他说话。

　　let后面可以跟一个被动的、不带to的不定式：

　　He let it be known that the house was his.他让大家知道那房子是他的。

　　但是let一般不用于被动意义来表示"被允许"，这时可用allow:

　　They didn't let us speak.他们没有让我们讲话。

　　We were not allowed to speak.我们没有被允许讲话。
