Population用法

Population用法 population是一个集合名词(无复数形式),它的用法有时较为特殊,所以很容易用错。 下面谈一下它的用法: 一、population常与定冠词the连用,作主语用时,谓语动词常用第三人称单数形式。 例如: The world\'s population is increasing faster and faster. 全世界的人口增长得越来越快。 At the beginning of the twentieth century, the world\'s population was about 1,700 million. 在二十世纪初,全世界的人口大约是十七亿。 二、当主语是表示\"人口的百分之几、几分之几\"时,谓语动词用复数形式。 例如: About seventy percent of the population in China are farmers. 中国大约有百分之七十的人口是农民。 三、有时population可用作可数名词,其前可用不定冠词。 例如: China has a population of about 1.3 billion. (=There is a population of about 1.3 billion in China.) 中国大约有十三亿人口。 New York is a big city with a population of over 10 million. 纽约是一个有一千多万人口的大城市。 在表示多个地区的人口时,population要用复数形式populations。 例如: Many parts of the world, which once had large populations and produced plenty of crops, have become deserts. 世界上很多地区一度人口众多,种植大量的农作物;现在,这些地区已经变成了沙漠。 四、表示人口的\"多\"或\"少\",不用\"much\"或\"little\",而要用\"large\"或\"small\"。 例如: India has a large population. 印度人口众多。 Singapore has a small population. 新加坡人口少。 五、询问某国、某地有多少人口时,不用\"How much...?\",而用\"How large...?\";在问具体人口时用\"What...?\" 例如: -How large is the population of your hometown? 你们家乡有多少人口? -The population of our hometown is nearly twice as large as that of yours. 我们家乡的人口是你们家乡人口的将近两倍。 -What is the population of Canada? 加拿大的人口有多少? -The population of Canada is about 29 million. 加拿大的人口大约有二千九百万。 六、population还表示\"某地、某类的动、植物或物品的总数\"。 例如: In India, however, the population of tigers has increased, from 2,000 in 1972 to about 5,000 in 1989. 然而在印度,老虎的总数已从1972年的2,000只增长到了1989年的大约5,000只。

数词用法归纳

▲掌握小数,分数、百分数和时间、日期的表达法。 【复习要点】 (一)基数词num. 基数词用来表示数目,或者说表示数量的词叫基数词。最基本的基数词如下表所示。 1 one 11 eleven 100 a hundred 2 two 12 twelve 20 twenty 1000 a thousand 3 three 13 thirteen 30 thirty 1,000,000 a million 4 four 14 fourteen 40 forty 10,000,000 ten million 5 five 15 fifteen 50 fifty 100,000,000 a hundred million 6 six 16 sixteen 60 sixty 1,000,000,000 a billion 7 seven 17 seventeen 70 seventy 8 eight 18 eighteen 80 eighty 9 nine 19 nineteen 90 ninety 10 ten 说明: 1.13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen 和fifteen。 2.20—90由个位数加后缀-ty构成,注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3.其它非整十的两位数21—99是由整十位数加连字符“-”,再加个位数构成。如:81 eighty-one。 4.101—999的基数词先写百位数,后加and再写十位数和个位数。如:691 six hundred and ninety-one。5.1000以上的基数词先写千位数,后写百位数,再加and,最后写十位数和个位数。 如:5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词,没有单独表示“万”、“亿”的单位词,而是用thousand(千)和million(百万)来表达,其换算关系为:1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 Hundreds of Thousands of 6.多位数的读法: 1)1000以上的多位数,要使用计数间隔或逗号“,”。即从个位起,每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand(千),第二个间隔或逗号前是million(百万),第三个间隔或逗号前是a thousand million或a billion(十亿)。 2)每隔三位分段以后就都成了101—999。读的时候十位数(或个位数)的前面一般要加and。如: 888,000,000读作:eight hundred and eighty-eight million。 基数词的用法: 1. 基数词在句中的作用 基数词的作用相当于名词和形容词,在句中可作定语、主语、宾语(介宾)、表语、同位语等。 例如:Three and five is eight. 3+5=8 (作表语)How many oranges do you want?你要多少桔子? I want eight. 我要八个。(作宾语)There are eight boats in the lake. 湖里有八条小船。(作定语) 2.Hundred, thousand, million, dozen, score这些词前面如有表示具体数字的词,它们不能加“s”,反之则须加“s”, 并要与of短语连用。例如:

鲁教版英语八上Unit6Howlonghaveyoubeencollectingshellsword

I have been reading Tolstoy's "War and Pea ce"→我一直在读托尔斯泰的《战争与和平》。(从过去开始读,现在还没有读完) 当然,也有意思基本相同的情况: I have lived in Japan for 3 years.=I have been living in Japan for 3 years. Step 3. 怎样区别现在完成时和现在完成进行时 比较一下现在完成时和现在完成进行时。在比较这两个时态时,关键在于对现在完成进行时的基本概念是否理解,因为对于现在完成时我们已经有了一个基本的理解了。 现在完成进行时是一兼有现在完成时和现在进行时二者基本特点的时态。由于它有现在完成时的特点,所以它可以表示某一动作对现在产生的结果或影响。由于它有现在进行时的特点,所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。 现在就现在完成进行时的这些特点和现在完成时作一简单的比较: (1)现在完成进行时和现在完成时皆可表示动作对现在产生的结果,但前者所表示的结果是直接的,而后者所表示的则是最后的结果。如: We have been cleaning the classroom.(a) We have cleaned the classroom.(b) (a)句可译为“我们打扫教室来着。”其直接结果可能是:我们身上都是灰。(b)句可以译为“我们把教室打扫过了。”其结果是:现在教室很清洁,可以用了。又,(a)句表示教室刚刚打扫过,(b)句则可能表示教室是昨天打扫的。 Be careful! John has been painting the door.(a) John has painted the door.(b) (a)句表示约翰刚刚把门油漆过,现在油漆还未干,所以你要小心。(b)句则无此含义,油漆可能已干了。 (2)现在完成进行时有时有延续性,现在完成时往往没有。如: They have been widening the road.(a) They have widened the road.(b (a)句的意思是他们在加宽马路,但尚未完工。(b)句的意思则是已完工了。有时现在完成时有延续性(如一些属于持续体的动词),但无临时性质。如: Mr. Smith has been living in London since 1978.(a) Mr. Smith has lived in London since 1979.(b) (a)句有“史密斯先生在伦敦久居”的含义,(b)句则没有。

several many 与hundred组合用法

我对hundred, thousand和million三词用法的困惑 我们先看看几道中考试题: 1. Many ______ trees should be planted on the mountains. (2007年山东青岛) A.thousand B.thousand of C. thousands D.thousands of 答案:D 2. In our school several ______ students are able to search the Internet for useful information now. (2003年江苏盐城) A. hundred of B. hundreds for C. hundred D.hundreds 答案:C 3. Beijing is a beautiful city. And ______ foreigh friends come to visit Beijing every month. (2010年贵州铜仁中考样卷) A.many thousand of B. several thousands C. two thousands D.thousands of 答案:D 大家知道,中考在考查学生数词的用法时,hundred, thousand和million三词用法是考查热点。我们都知道当它们前面有具体的数词修饰时,hundred, thousand和million不能加-s, 当它们后面接of时,它们必须加-s. 不管哪种情况,它们都是直接接名词,名词前不能有限定词。 但是,如果hundred, thousand和million前面有many和several等不确定的数修饰时,该如何表达呢?通过上面三题的参考答案,我们可以得出这么一个结论:many是个概数,可以组成many(hundreds, thousands, millions)of +名词复数;several相当于一个具体的数字,组成several((hundred, thousand, million)+名词复数。 然而,笔者查阅了大量资料,似乎又不是这样。关于它们的用法,有的甚至截然相反。 第一种说法:(《牛津高级英汉词典》)P864 hundred的用法之一:“说a, one, two,several,etc.hundred时,hundred后面不加-s; 若前面没有数目或数量,可用hundreds(of…)。Hundred或hundreds均用复数动词”。 这里它把several看成了具体数词。上面第二题选C可能就是这么来的。 第二种说法:(《英语基础词汇用法详解词典》)P836 “下面两个短语都有‘几百人’的意思:several hundred of people; several hundreds of people”。 照这种说法,上面第二题似乎应该选A才对。 第三种说法:(《大学英语语法讲座与测试》)P42 Note: ①当hundred of,thousand of,million of被a few,some,several,many等表示不确定的数的词修饰时,用单数形式或复数形式均可。例如: Several hundred(s) of workers attended the meeting. Some thousand(s) of soldiers were sent there. Many million(s) of birds fly to the south in winter. ②比较下面两句: She earned several hundred(thousand).(用单数) She earned some(many) hundreds(thousands).(用复数) 照这种说法,上面第一题B,D都对;第二题A,C都对;第三题A,B,D都对。

how long 与how soon的用法区别

how long,how soon和how often都含有how,并且都和“多长时间、多久”有关,但它们的用法不相同。 how long意为“多久、多长时间”,主要是对一段时间进行提问,答语通常是(for)three days/weeks/months等时间段,它可用于各种时态。 How long do you stay in Beijing every year? 每年你在北京住多久? How long have they lived here? 他们住在这里有多久了? —How long were you not at school last year? 去年你多久没上学? —About two weeks. 约两周。 ________________________________________________ how soon意为“还要多久”,是对从某个基本时间到将来某动作结束或某动作发生这段时间提问,常用在一般将来时态的句子中,其答语通常是“in + 一段时间”。 —How soon can you finish the work? 还要多久你能完成这项工作? —In half an hour. 半小时后。 ______________________________________________ how often意为“多久……次、是否经常”,用来提问在某一特定的时间进行某个动作的次数,答语通常是always,usually,often,sometimes,once/twice a day/month等。 —How often do you get to school very early? 你多久早到校一次? —Usually. 通常。 —How often do you see a film? 你多久看一次电影? —Once a month. 每月一次。 _______________________________________________ 自我测试○○○○○○○○○○○○ 选择填空。 1.— _______ did the meeting last? —About half an hour. A. How soon B. How long C. How far D. How much 2.— _______ will Ezhou-Huanggang Bridge be finished? —In a few months. A. How soon B. How long C. How often D. How far
