例句难点解析_英语论文

1.What do you think they should do to solve their problems?

　　 此句为双重疑问句,由一般疑问句和特殊疑问句混合而成。 
掌握该句型需要注意以下几点:①一般疑问句(如本句的do you think)用疑问语序;②特殊疑问句应注意形式或语序的变化,即特殊疑问词提到句首(如本句的what),并用陈述语序;③可用于此句型的动词除think之外,还有say, believe, guess, suggest, imagine, suppose等。如:

　　 Where do you guess we can see him?

　　 你认为我们能在什么地方见到他?

　　 Who do you think we must ask for help?

　　 你认为我们该找谁帮忙?

　　2.Chuck survives the crash and lands on a deserted island.

　　 survive既可以用作及物动词,表示“经历……活下来”,也可用作不及物动词,表示“活下来”。如:

　　 Only a few soldiers survived the battle.

　　 经过那次战斗,仅有少数士兵幸存。

　　 She survived in the desert for a week on biscuits and water. 她在沙漠中靠饼干和水活了1周。

　　3.He realises that he hasn’t been a very good friend because he has always been thinking about himself.

　　 句子中has always been thinking about himself是现在完成进行时态,说明某动作或状态从过去某时刻开始一直延续到现在,有可能继续进行下去,也有可能刚刚结束,其中副词always用来加强语气。如:

　　 Mr Jones has been picking the apples at his farm with his children.

　　 琼斯先生一直在他的农场和他的孩子们一起摘苹果。

　　 Where have you been? We have been looking for you.

　　 你去哪里了?我们一直在找你。

4.The lesson we can learn from Chuck and all the others who have unusual friends is that friends are teachers.

　　 该句的主句为The lesson...is that...。 
其中we can learn...unusual friends为定语从句,修饰先行词the lesson; who have unusual friends为另一定语从句,修饰先行词the others;that引导的从句为名词性从句,在句中作表语。

　　 名词lesson在这里表示“体会,教训”,常构成词组learn a lesson from...表示“从……得到教训”,teach sb. a lesson 表示“给某人一个教训”,而give sb. a lesson除表示“给某人一个教训”之外,还可表示“给某人上课”。如:

　　 His father will teach the boy a lesson if he doesn’t work hard.

　　 如果那个男孩不努力学习的话,他父亲将会教训他。

　　 What lesson can you learn from this story you read?

　　 你从刚读的这个故事中能获得什么体会(教训)?
