ENVIRONMENT REPORT - November 23, 2001: Population and the Environment
By Cynthia Kirk
This is the VOA Special English ENVIRONMENT REPORT.
A new report says the growing population around the world is harming the environment. More people are using more of the Earth’s natural resources than ever before. Experts say poor people around the world will suffer most in the future unless environmental damage is stopped. They say more should be done to balance human and environmental needs.
The United Nations Population Fund is responsible for studying population growth. It released the report about the subject earlier this month. The report is called the State of the World Population, Two-Thousand-One. It examines the links among environmental conditions, population growth and efforts to help poor people in developing countries.
The world’s population is now more than six-thousand-million people. That number has increased by one-hundred percent since Nineteen-Sixty. The population is expected to increase to more than nine-thousand-million by the year Two-Thousand-Fifty.
The report says about two-thousand-million people lack food security. Water supplies and agricultural lands are heavily used. In fifty years, experts say more than four-thousand million people will be living in countries that can not meet people’s daily needs.
The report says all of the expected growth in world population will take place in developing countries. The forty-nine least developed countries are expected to increase by almost two-hundred percent in fifty years.
Yet, the U-N agency says people in the richest countries use much more of the world’s resources than people in developing countries. It says a child born today in the United States, France or Japan will do more harm to the environment during his lifetime than as many as fifty children born in developing countries.
The U-N Population Fund says international policies need to be put into effect to improve poor conditions, increase social development and ease pressure on the environment. It also says women need more control over their lives. It says empowering women would lead to smaller families and slower population growth. The U-N Population Fund says these measures would help improve the well being of growing populations while protecting the natural world.

非谓语动词的用法总结 李靖 非谓语动词（不定式、动名词、分词）不是真正意义上的谓语动词，在句中都不能单独作谓语。但都具有动词的某些特点，可以有自己的宾语或状语，构成非谓语动词短语。不定式表目的，表将来；动名词表主动，表进行；过去分词表被动，表完成。 一．作主语( 动名词、不定式、过去分词前面加being, 动名词做主语谓语动词用单数) 1）不定式、动名词都可做主语，但是动名词做主语多指抽象的概念性的动作，可以是多次的经常的行为；不定式多表示具体的动作，尤其是某一次的动作。如： Playing with fire is dangerous. 玩火危险。（泛指玩火） To play with fire will be dangerous. 玩火会发生危险。 2）用动名词做主语的句型: It’s no use/no good/pleasure doing sth 做.......没有用处/好处/乐趣 It’s a waste of time doing sth 做.... 浪费时间 It is worth doing sth 值得做某事 It is no use crying over spilt milk. 覆水难收 It is worth making an appointment before you go. 去之前预约一下是值得的。 3）不定式做主语的句型. It is + adj +for sb to do sth. 比较：表示人的品质时只能用of sb 如considerate/kind/nice/foolish/stupid/rude/cruel /wise/clever/brave/selfish/crazy/good/careful/careless/impolite/right/wrong等单词出现 时。 It is silly of you to say so. It is important for us to learn English well. It is a must/ a necessity for us to have a good command of the English language. 4) “Wh- + to 不定式”可做主语。如： When to leave hasn’t been decided yet.什么时候动身还没定呢。 Whether to drive or take the train is still a problem.是自驾车还是乘火车仍是一个问题。 5）一般情况下，不定式和动名词作主语，谓语动词一般用单数形式。如： Seeing is believing.= To see is to believe 眼见为实。 . Planting flowers needs constant watering. 但and连接的多个动名词作主语，谓语动词大多用复数（如果前后动名词的语义一致， 谓语一般用单数）。如：Lying and stealing are immoral. 说谎与盗窃是不道德的。 6) 动名词前面可以加上形容词性物主代词构成动名词的复合结构。如： ----- What made him angry? ------ Mary’s /My/His/Her /Their/ The boy’s/ The president’s being late（made him angry. 7being，构成动名词，做主语。如： . Being examined twice a year , driver must obey in this city. 经典练习：

二．不定式的用法 不定式不可作谓语，但它可以有自己的宾语、状语，构成不定式短语，在句中可以作主语、宾语、表语、定语（表用途）、状语或补足语。高考对不定式的考查主要有不定式的时态、语态、作用、否定、省略、连词＋不定式等。 作主语 不定式作主语表示具体的动作，通常指一件已知的事或目的。 不定式作主语时，谓语动词用单数。 eg:To say is a thing,to do is another.(说是一回事，做是另外一回事。)
（2）不定式短语较长时，通常放在谓语之后，用it作形式主语。 eg:①It is important to learn English well.(学好英语是重要的。) ②It is necessary for us to do the job well.(我们做好这项工作是必要的。) ③It is a great honor to be invited to give a speech here.(被邀请在这儿发表演讲是一个极大的荣幸。) 2.作宾语 （1）常只用不定式作宾语的动词有：want,wish,hope,long,expect,desire,intend ,decide,ask,promise,aim,offer,agree,plan,l earn,choose,refuse,fail,manage,pretend 等。 eg:①He refused to help me.(他拒绝帮助我.) ②She has agreed to come

英语非谓语动词用法总结(完整) 一、单项选择非谓语动词 1．---_________ makes your son feel blue today? ---_________ to watch his favourite cartoon Paw Patrol. A．What it is that; To be forbidden B．What is that; Forbidden C．What is it that; Being forbidden D．That is what; Having forbidden 【答案】C 【解析】 【详解】 考查强调句型和非谓语动词。句意：——是什么让你儿子今天心情不好？——不让他看他最喜欢的卡通《狗狗巡逻队》。分析句子结构可知，第一空为强调句型的特殊疑问句，即：疑问词What+ it is+ that+其余部分；第二空为非谓语动词，作主语用动名词，且son与forbide之间是被动关系，所以用Being forbidden，故C项正确。 【点睛】 注意强调句型的特殊疑问句形式为：疑问词+ it is+ that+其余部分，根据句意“是什么让你儿子今天心情不好？”判断疑问词用what，即：What is it that makes your son feel blue today? 2．(福建) ___________the past year as an exchange student in Hong Kong, Linda appears more mature than those of her age. A．Spending B．Spent C．Having spent D．To spend 【答案】C 【解析】 试题分析：“花费”和其逻辑主语“Linda”之间是主动关系，故用现在分词作原因状语。且“花费”的动作明显早于“看起来成熟”这个动作。表示发生在谓语动作之前的动作，用现在分词的完成时。句意：由于Linda过去几年在香港作交换留学生，所以她看起来比她的实际年龄更成熟。 考点：考查非谓语动词的用法。 3．Tsinghua University,________ in 1911,is home to a great number of outstanding figures. A．found B．founding C．founded D．to be founded 【答案】C 【解析】考查非谓语动词。句意: 建立于1911年的清华大学是大量杰出人物的母校。Tsinghua University和found之间是被动关系, 故用过去分词作后置定语, 选C。 4．More highways have been built in China, _____ it much easier for people to travel from one place to another.

非谓语动词用法归纳 非谓语动词 在英语中，动词不定式、动名词和分词（包括现在分词和过去分词）可以出现在句子中除谓语以外的任何一个位置上，充当句子的主语、宾语、表语、定语、状语、补语等成分，这些动词形式称为非谓语动词。 1．不定式和动名词作主语的区别 (1)动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。 Smoking is prohibited(禁止)here．这里禁止抽烟。(抽象) It is not very good for you to smoke so much．你抽这么多烟对你身体很不好。(具体) (2)动名词作主语时，通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。 Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验) （3）不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。 It took me only five minutes to finish the job. 2．不定式、动名词和分词作表语的区别 (1)不定式作表语 1)不定式作表语一般表示具体动作，特别是表示将来的动作。 To do two things at a time is to do neither．--次做两件事等于未做。 2）如果主语是不定式（表示条件），表语也是不定式（表示结果）。 To see is to believe.百闻不如一见。 3)如果主语是以aim，duty，hope，idea，happiness，job，plan，problem，purpose，thing，wish等为中心的名词，或以what引导的名词性从句，不定式作表语是对主语起补充说明作用。 His wish is to buy a luxurious car in the near future．他的希望是在不远的将来买一辆豪华轿车。 (2)动名词作表语：动名词作表语，表示抽象的一般性的行为。 Our work is serving the people．我们的工作是为人民服务。 (注)动名词作表语时与进行时态中的现在分词形式相同，但其所属结构迥异，进行时态说明动作是由主语完成的。动名词做表语，说明主语的性质或情况。 His victory in the final was no more convincing than I had expected． (3)分词作表语 分词做表语有两种情况，一种是现在分词做表语，一种是过去分词做表语，这两者区别是考试中经常考到的地方。一般来说，表示心理状态的动词如excite，interest等都是及物动词，汉语意思不是“激动”，“高兴”，而是“使激动”、“使高兴”，因而现在分词应该是“令人激动的”、“令人高兴的”，过去分词则是“感到激动的”和“感到高兴的”。所以，凡表示“令人……的”都是-ing形式，凡是表示“感到……”都用-ed形式。 3．不定式和动名词作宾语的区别 英语中大多数动词既可跟不定式，也可跟动名词作直接宾语，但有些动词要求： (1)不定式做宾语和宾语补足语 1)下面的动词要求不定式做宾语(部分)： attempt企图enable能够neglect忽视 afford负担得起demand要求long渴望 2)下面的动词要求不定式做宾补：动词+宾语+动词不定式： allow允许forbid禁止prefer喜欢，宁愿
[动词非谓语形式]非谓语动词的用法总结动词不定式 (一) 时态 1. 一般式 动词不定式的一般式表示与谓语动词同时或之后的行为。如： I want to have a rest I plan to attend the meeting 2. 完成式 不定式的完成式表示不定式的动作发生在谓语动词所表示的动作之前的行为。如： I ’m sorry to have kept you waiting. 3进行式 不定式的动作如果同谓语动词所表示的动作同时发生则使用不定式的进行式。如： They seemed to be talking about something important. 4. 完成进行式
不定式的完成进行式表示在谓语动词之前已经发生，并且一直进行着的动作。如： He is said to have been working in that factory for twelve years. （二）动词不定式用法： 1. 作主语 To master English gives us much help in the study of science 2. 作宾语 I want to leave here soon. He pretended to be a doctor. 3. 作表语 The most important thing is to study hard. 4. 作宾语补足语 不定式作定语必须放在被修饰的名词或代词的后面。 I have no time to talk with her. 6. 作状语 不定式作状语时可以表示目的、原因、结果或条件。 I came here to learn from you ( 目的) I ’m very glad to heard the news。（原因） He is old enough to go to school.(结果) To look at him ,you can’t help laughing.

A. download B. downloads C. to download D. downloading 【答案】 C 【解析】【分析】句意——你听说了中国正在建造全国5G网络吗？——对，5G将会让我 们比原来更快的速度下载英文电影。allow sb to do sth，允许某人做某事，固定短语，应使 用动词不定式，故答案是C。 【点评】考查动词不定式，注意识记固定搭配allow sb. to do sth结构。 5．The show was so funny that it made everyone ______ again and again.

英语非谓语动词用法总结（完整） 一、单项选择非谓语动词 1．After a decade or so, out of choices, he returned to where he 'd begun, ashamed at having so little to show for his wanderings. A．being run B．running C．to run D ．having run 【答案】D 【解析】 【详解】考查现在分词。句意：大约十年后，在没有选择的情况下，他回到了他开始的地方，为自己的拼搏没有什么收获而感到羞愧。run out of 用“光，耗尽”与主语he 在逻辑上是主动关系，且表示的动作明显发生在return 之前，所以用现在分词的完成时having run of。故D 选项正确。 【点睛】非谓语动词是考试考查的重点，要掌握它的用法。首先，要弄清楚填空处要填的是非谓语。其次，要知道非谓语动词的三种形式：现在分词表示主动进行、过去分词表示被动完成、动词不定式表示目的和将要。再次，要知道非谓语动作与谓语动作是同时发生还是先后发生，还是将要发生。其中分词做状语的考查尤为重要。 分析句子可知，本句的主语为he,谓语为returned, run out of 用光“，耗尽”为非谓语与主语he 在逻辑上是主动关系，且表示的动作明显发生在return 的之前，所以用现在分词的完成时having run of。故D选项正确。 2．At the age of 29, Dave was a worker, _______ in a small apartment near Boston and _________ what to do about his future. A．living; wondering B．lived; wondering C．lived; wondered D．living; wondered 【答案】A 【解析】 试题分析：现在分词做伴随状语，At the age of 29,D was a worker.这是完整句子,所以后面要用分词结构. 有and,显然是两个并列分词. 主要注意用现在分词，现在分词的主语就是主句的主语，它们之间的关系是主动关系。用现在分词做状语，DAVE在29 岁时是一名工人， 住在一间小公寓里，不知道未来会如何。选A。 考点：考查现在分词做状语点评：现在分词还是过去分词做状语主要取决于动词和逻辑主语的关系：如果动词和逻辑主语是被动关系，用过去分词，如果动词和逻辑主语是主动关系，用现在分词。 3．Young people may risk deaf if they are exposed to very loud music every day. A．to go B．to have gone C．going D．having gone 答案】C 解析】 risk 意为冒??的危险，用法为risk doing something ，冒险干某事，因此排除AB, D 项中额having done 意为已经干了某事，与此处句意不符，因此选择 C 项，句意为，如果年轻人每 天都暴露在非常吵闹的音乐声中，他们可能有耳朵失聪的危险。

A .Being exposed B.Exposed C.Having exposed D.To exposed 解析；选A。可能误选B。误认句子缺少状语，但观察可以发现若是作状语的话，那么句子就没有主语了。判断方法；划分句子的主谓宾。 3.动名词的复合结构；one’s doing /being done Eg.My sister’s being ill made us all worried =That my sister was ill made us all worried. 4.迁移；若主语与to do中的do 存在动宾关系，且形容词是hard. difficult 之类的，那么 do用主动态表示被动态。 Eg ;The question is hard to answer. 二．宾语 1．总结；doing;长期性的动作，其他的同上，被动态为being done。 to do ;短暂性的，已完成的动作，其他的同上，被动态为to be done。 2.,几种类型；①大部分动词+to do ②只加doing的；imagine.avoid.mistake.delay.deny.risk.mind.appreciate.escape等。 ③既可以加doing又可以加to do的，但意思不同的;regret remember forget admit 等（这些动词后面也可以加having done,其意思和加doing的时候一样） ④加doingd的时候表被动；need want require 等，这种情况下句子的主语一般是物。 ⑤一般情况下两者可以互换但某些情况下不能；start/begin,like/enjoy/love等，前者在句子主语是物的时候只能用to do(当然这只是其中一种情况了，还有其他的注意点)，而后者加to do时表示暂时的兴趣，而表示doing长久的兴趣. Eg;I like swimming,and I enjoy to run these days.(我一直都很喜欢游泳，但是我这段时间又喜欢跑步了，后者是暂时的兴趣，将来是否还喜欢就不知道了) 3.动名词的复合结构；①vt + one’s doing(mind,imagine,find等)，另外这类动词还可以将one’s 改成宾语，即doing变成了宾补了 ②介词+one’s doing/o+doing Eg;Would you mind my/me opening the window?
