新概念第二册摘要写作参考答案（Lessons 57）新概念英语第二册第57课词汇学习 Word study 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。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： Lets not waste any more time.我们别再浪费时间了。 Lets take a taxi.我们坐出租车吧。 其否定形式除Lets not外也能够用Dont lets： Dont lets 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lets： Please let us have more time, will you?请多给我们一点时间好吗? I wont let you ride my bicycle.我不让你骑我的自行车。 Let him speak.让他说话。 let后面能够跟一个被动的、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 didnt 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。新概念英语第二册第57课课后练习答案 Key to written exercises 1.难点练习答案 1 Dont let him bully you. 2 Why dont you make. him apologize for his behaviour? 3 No one can make me believe hes telling the truth. 4 Will your parents let you come to the theatre with us? 5 Lets go for
