11、LeiUnit7 词汇讲解1. populationpopulation意为“人口”时，是一个集体名词，被看作一个整体，在句中做主语时，后面的谓语动词用单数形式。例如：The population ofChinais large.中国人口众多。【拓展】（1） 当表示一个城市、地区或国家有多少人口时，常用以下两种结构，即“the population of + 某地 + is + 数词”或“某地 + has a population of + 数词”。The population of London is over ten million. =London has a population of

12、 over ten million.伦敦的人口超过一千万。（2） population可与large，small搭配，但不能与many，few搭配。The city with its large population has become crowded.这个人口众多的城市变得拥挤不堪了。（3） 询问人口数量常用what或how large。Whats the population of the city? =How large is the population of the city?这个城市有多少人口？（4） population前有修饰词，如分数、百分数时，表示整体人口中的一部分，谓语

13、动词用复数形式。One half of the population of the city are farmers.这个城市的一半人口是农民。2. protectprotect作及物动词，意为“保护”。常用搭配protect sb./sth. from/against，意为“保护某人/某物免受伤害”。We should protect rare animals.我们应该保护珍稀动物。Parents protect their young from danger.父母保护他们的儿女不受伤害。3. includeinclude作动词，意为“包括；包含”。The price for the hot

14、el includes breakfast.旅店的费用包括早餐在内。The parcel included a dictionary.那包裹里有一本字典。including除了是include的现在分词/动名词之外，在日常运用中一般被当作介词使用，和其后的名词/代词一起形成介宾短语，意思是“包括在内”。There are many different kinds of moon cakes, including fruit, coffee and ham.有很多种月饼，包括水果的，咖啡的和火腿月饼。There are 40 students in the classroom, includin

15、g me.班里有40名学生，包括我在内。同样，included也有介词用法，且：including + 宾语 = 宾语 + included。所以上个例句亦可写成：There are 40 students in the classroom, me included.4. succeedsucceed作不及物动词，意为“成功”；表示做某事做成功了，succeed 后通常接in doing sth。His plan succeeded.他的计划成功了。At last he succeeded in solving the problem.他终于把那个问题解决了。She succeeded in

16、passing the exam. 她考试及格了。（1）success 表示抽象意义的“成功”，作不可数名词；表示具体意义的“成功的人或事”, 则是可数名词。Failure is the mother of success.失败是成功之母。His new book was a great success.他新出版的书获得了巨大成功。（2）successful作形容词，意为“成功的”。The performance was successful. 演出很成功。It was a successful experiment.那是一次成功的试验。5. achieve（1）achieve作及物动词，意为

17、“完成；实现”。You will never achieve anything if you spend your time that way.你若总是这样消磨时间，就永远不会有所成就。Everybody should be given the chance to achieve their aims.要让每个人都有机会实现自己的目标。No one can achieve anything without effort.谁也不可能不努力而有所作为。（2）achieve作及物动词，意为“达到；赢得”。The actor achieved fame when he was only ninetee

18、n.那位演员十九岁时就成名了。She achieved no success. 她没有获得成功。achievement作名词，意为“成就；成绩”。The invention of the computer is a great achievement.发明电脑是一大成就。6. force（1）force作名词，意为“力；力量；武力”。The force of the explosion broke all the windows in the building.爆炸的力量震碎了这座建筑上的所有窗户。The law should remain in force.法律应当有效力。Well sett

19、le the problem by force if necessary.如果有必要的话，我们会用武力解决这个问题。（2）force作动词，意为“强迫”。force sb. to do sth.意为“强迫某人做某事”。I cant force him to stay.我不能强迫他暂时留下来。7. weighweigh表示“称的重量”，是及物动词；表示“重（多少）”，是不及物动词。He weighed the fish. 他称了这条鱼。Do you often weigh yourself? 你经常称体重吗?He weighs 60 kilos. 他体重60公斤。The meat weighs

20、five pounds. 这肉重五磅。weight是名词，意为“重量，体重”。Whats your weight? 你体重是多少？比较：by weight 和 in weightby weight表示“按重量”，in weight表示“重量上”。Do they charge carriage by weight?他们是按重量收取运费吗?Its smaller in size but greater in weight.它体积比较小，但分量比较重。8. take intake in意为“吸入；吞入（体内）”。On weekends the Smiths usually drive to the

21、countryside and take in the fresh air there.周末，史密斯一家常驱车到农村去呼吸那里的新鲜空气。（1）take in意为“领会；理解”。Before you translate a sentence, you should first take in the meaning of the words.动手翻译句子之前，首先要理解单词的含义。（2）take in意为“欺骗；蒙蔽”。Law will protect the girl taken in and sold by the abductor.法律将保护那位被人贩子欺骗和拐卖的姑娘。（3） take

22、 in意为“接收；收留”。The poor man had nowhere to live in, so we took him in.那个可怜的人没有地方住，所以我们让他住在我家。练一练：I. 英汉短语互译。1出生时_2跌倒_3和某人一起玩_4砍伐_5吸入；吞入（体内）_6in the future_7talk about_8walk into_9as far as I know_10give up_II. 根据汉语或首字母提示完成单词。1Every year thousands of t_ come to visit my hometown2The Great Wall is an a_

This spirit of these climbers shows us that we should never give up trying to achieve our dreams.give up是动词短语，意为“放弃；停止；戒除”。give up doing something意为“放弃做某事；半途而废”。She doesnt give

27、 up easily. 她不会轻易放弃。The doctors had given her up but she made a remarkable recovery.医生们已放弃了治愈她的希望，而她却恢复得很好。You ought to give up smoking; I gave it up last year.你应该戒烟，我去年就戒掉了。give的相关短语：give away赠送，分发；give off放出，释放；give in屈服，让步；give out分发，用完；give back归还3. Scientists say there are now fewer than 2,000

28、pandas living in the remaining forests.本句中living in the remaining forests为现在分词短语，修饰名词pandas。分词短语作定语时，应置于被修饰名词之后。The man standing by the window is our teacher.站在窗边的那个人是我们老师。（standing by the window就是一短语，也就是说不是一个单词，在此作定语表主动）Suddenly there appeared a young woman dressed in green.突然出现一个穿绿色衣服的女青年。（过去分词短语作定语表被动或完成）【注意】区别：现在分词作定语表示动作正在发生或与谓语动作同时（或基本同时）发生，表示主动意义；及物动词的过去分词作定语表完成或被动的动作；不及物动词的过去分词作定语只表完成不表
