中国有凌驾 5000 的悠久历史。比美国的历史长多了。中国有世界最高山峰。

词汇:as…as, population,the Yangtze River ,the third longest ,much longer, Qomolangma【优秀满分范文】Dear Dave, I’m happy to be your pen pal. I’d like to tell you something about China. China is the biggest country in Asia. It’s almost as big as the USA. China has the biggest population in the world. The people here are friendly and hard-working. The Yangtze River is one of the longest rivers in the world. China is over 5000 years old. It has a much longer history than the US. The Qomolangma is the highest mountain in the world. I love China very much. Welcome to China and play with me. Yours,Li LeiUnit7 词汇解说1. populationpopulation意为“人口”时,是一个团体名词,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) 当表现一个都会、地域或国家有几多人口时,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”。

例如: The population of London is over ten million. = London has a population of over ten million. 伦敦的人口凌驾一千万。(2) population可与large,small搭配,但不能与many,few搭配。例如: The city with its large population has become crowded. 这小我私家口众多的都会变得拥挤不堪了。(3) 询问人口数量常用what或how large。

例如: What’s the population of the city? = How large is the population of the city? 这个都会有几多人口?(4) population前有修饰词,如分数、百分数时,表现整体人口中的一部门,谓语动词用复数形式。例如: One half of the population of the city are farmers. 这个都会的一半人口是农民。2. protectprotect作及物动词,意为“掩护”。常用搭配protect sb./sth. from/against…,意为“掩护某人/某物免受……伤害”。

例如: We should protect rare animals. 我们应该掩护珍稀动物。Parents protect their young from danger. 怙恃掩护他们的后代不受伤害。3. includeinclude作动词,意为“包罗;包罗”。

例如: The price for the hotel includes breakfast. 旅馆的用度包罗早餐在内。The parcel included a dictionary. 那包裹里有一本字典。【拓展】including除了是include的现在分词/动名词之外,在日常运用中一般被看成介词使用,和其后的名词/代词一起形成介宾短语,意思是“包罗……在内”。

例如: There are many different kinds of moon cakes, including fruit, coffee and ham. 有许多种月饼,包罗水果的,咖啡的和火腿月饼。There are 40 students in the classroom, including me. 班里有40名学生,包罗我在内。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“乐成”;表现做某事做乐成了,succeed 后通常接in doing sth。例如: His plan succeeded.他的计划乐成了。At last he succeeded in solving the problem. 他终于把谁人问题解决了。

She succeeded in passing the exam. 她考试及格了。【拓展】(1)success 表现抽象意义的“乐成”,作不行数名词;表现详细意义的“乐成的人或事”, 则是可数名词。例如: Failure is the mother of success. 失败是乐成之母。

His new book was a great success. 他新出书的书获得了庞大乐成。(2)successful作形容词,意为“乐成的”。例如: The performance was successful. 演出很乐成。

It was a successful experiment. 那是一次乐成的试验。5. achieve(1)achieve作及物动词,意为“完成;实现”。

例如: 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. 要让每小我私家都有时机实现自己的目的。No one can achieve anything without effort. 谁也不行能不努力而有所作为。(2)achieve作及物动词,意为“到达;赢得”。

例如: The actor achieved fame when he was only nineteen. 那位演员十九岁时就成名了。She achieved no success. 她没有获得乐成。

【拓展】achievement作名词,意为“成就;结果”。例如: The invention of the computer is a great achievement. 发现电脑是一大成就。

6. force(1)force作名词,意为“力;气力;武力”。例如: The force of the explosion broke all the windows in the building. 爆炸的气力震碎了这座修建上的所有窗户。

The law should remain in force. 执法应当有效力。We’ll settle the problem by force if necessary. 如果有须要的话,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”。例如: I can’t force him to stay. 我不能强迫他暂时留下来。7. weighweigh表现“称……的重量”,是及物动词;表现“重(几多)”,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 five pounds. 这肉重五磅。【拓展】weight是名词,意为“重量,体重”。

例如: What’s your weight? 你体重是几多?比力:by weight 和 in weightby weight表现“按重量”,in weight表现“重量上”。例如: Do they charge carriage by weight? 他们是按重量收取运费吗? It’s smaller in size but greater in weight. 它体积比力小,但分量比力重。

8. take intake in意为“吸入;吞入(体内)”。例如:On weekends the Smiths usually drive to the countryside and take in the fresh air there.周末,史女士一家常驱车到农村去呼吸那里的新鲜空气。

【拓展】(1)take in意为“领会;明白”。例如: Before you translate a sentence, you should first take in the meaning of the words. 动手翻译句子之前,首先要明白单词的寄义。(2)take in意为“欺骗;蒙蔽”。

LOL全球总决赛下注

例如: Law will protect the girl taken in and sold by the abductor. 执法将掩护那位被人市井欺骗和拐卖的女人。(3) take in意为“吸收;收留”。例如: The poor man had nowhere to live in, so we took him in. 谁人可怜的人没有地方住,所以我们让他住在我家。

As far as I know, there are no man-made objects as big as this.as far as I know是一个牢固表达方式,还可以说so far as I know,意为“据我所知”。

例如: As far as I know, Wang Tao has two brothers. 据我所知,王涛有俩弟弟。They’re not coming this Sunday, so far as I know. 他们这周日不来了——就我所知是这样的。

2. 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;中途而废”。

例如: She doesn’t give 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。【拓展】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送还3. Scientists say there are now fewer than 2,000 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。例如: The man standing by the window is our teacher. 站在窗边的谁人人是我们老师。(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. 突然泛起一个穿绿色衣服的女青年。

(已往分词短语作定语表被动或完成)【注意】区别:现在分词作定语表现行动正在发生或与谓语行动同时(或基本同时)发生,表现主动意义;及物动词的已往分词作定语表完成或被动的行动;不及物动词的已往分词作定语只表完成不表被动的行动。例如: They lived in the house facing the south. 他们住在朝南的屋子里。(现在分词作定语表现主动意义) The meeting held yesterday is important. 昨天开的集会很重要。

(及物动词的已往分词表被动或完成)(2)分词短语作定语相当于一个定语从句,修饰前面的名词。例如: The man reading a novel at the desk is my father.(现在分词表“主动、正在”) = The man who is reading a novel at the desk is my father. 在桌边读小说的人是我父亲。Is there anything planned for tonight? (已往分词表“被动、已经”) = Is there anything that has been planned for tonight? 今晚有什么运动吗?4. Pandas do not have many babies, maybe one every two years.every+ 基数词+ 复数名词=every+ 序数词+ 单数名词,作“每(几多)”解。

例如:every three days 每三天或每隔两天相当于 every third day We hand in our homework every three days. 我们每隔两天(每三天)交一次作业。【拓展】(1)“every other+单数名词”意为“每隔一……”。例如:every other day 每隔一天 every other tree 每隔一棵树(2)“every few+复数名词”意为“每隔几……”。

例如:every few days每隔几天5. One of the world’s most dangerous sports is mountain climbing…one of +the +形容词最高级+复数名词/代词,意为“最……之一”,当其作主语时,谓语动词用单数形式。例如: His brother is one of the tallest boys in the class. 他弟弟是这个班最高的男生之一。The song is one of the most popular songs. 这首歌是最盛行的歌之一。

One of us has nothing for breakfast. 我们中有一小我私家没吃早饭。练一练:I.连词成句。1.the,what’s,cheapest,in,the,car,store _______________________________?2.Mary,her,a,is,lot,serious,more,than,sister _______________________________.3.David,as,is,as,me,clever _______________________________.4.the,animals,has,more,zoo,than,that,one _______________________________.5.the,theater,best,what’s,movie _______________________________ ?II. 句型转换,按要求完成下列句子。
