8、细心处理垃圾，禁止砍树。（禁止做某事：discourage doing sth ）4、What a large population ! 人口真多啊！population 意为“人口”，当强调人口的多少时，可以用large/ big/ small等形容词来修饰。 The population of is very large. 中国人口众多。 Whats the population of China ? 中国有多少人口？ -1.3.billion.总结：句中，population，是个集合名词，当表示“某地整体人口的数量”时，做主语，谓语动词用_(单数、复数)形式。但是，看例句：80% of

9、 the population in China are farmers. 中国百分之八十的人口是农民。 当“强调人口的具体分布或构成”时，做主语，谓语动词用_(单数、复数)形式。句中，针对人口数量提问时，特殊疑问词用_；练习：( ) 1.1. _ is the population of Indonesia? 223 million. A. How much B. How many C.

11、万”的短语是：_；当表示一个不确定的数字时，要在这几个单词后加_, 并且要和介词_连用，构成词组，表示一个概数。两千本书 two thousand books ； 四百个学生four hundred students思考：“与具体数字相连时”，hundred，thousand后面是加s，还是不加s ？_几千人 a few/ several thousand people (注意：thousand有没有加s)思考：hundred，thousand被_和_修饰时，hundred，thousand不加s。【练一练】( ) The population has increased _ 15 perce

14、ing to a place like that.我真讨厌去那样一个地方。 -So do I.我也是。So do I. - 完全倒装句，含义是：A如此，B也如此，意为“某某也一样”，结构为“so+be/情态动词/助动词+另一个主语”。此句所用的时态要与前句的时态相同，“be/情态动词/助动词”的形式要与后面的主语一致。如：-Kangkang is a good student.康康是个好学生。-So is Maria.玛利亚也一样。-They must come.他们必须来。-So must I.我也一样-Lucy sings very well.露西唱得很好。-So does Lily.莉莉

15、也一样。-Tome has finished the task.汤姆完成了那项任务。-So have I.我也一样。上述结构的否定形式为：Neither / Nor + be / 助动词 / 情态动词 + 主语 - A不是这样，B也不是这样如果表示赞同，用“so+主语+be/情态动词/助动词”这一结构，意为“的确如此”，主语与上文指同一人或物。如：-It was cold yesterday.昨天很冷。-So it was.是的，昨天的确很冷。-How fast she runs!她跑得多快！-So she does.是的，她的确跑得很快！典例：a.

18、 than that in developed countries, doesnt it?此句译成: .句中“that”用来指代 ，在形容词比较级的句子中，用 指代前面出现的单数名词，用 指代前面出现的复数名词。eg: The weather in Beijing is colder than in Fuzhou. The roads here are wider than in my hometown.6、he population in developing countries is growing faster. So it is.So it is译成:的确是如后者对前者的陈述表示一致时

19、，意为“的确如此”，结构为“so +主语+ be/情态动词/ 助动词”。eg: Jim is a good student. . 吉姆是一名好学生，的确如此。Jim swims well. . 吉姆游泳很好，的确如此。Section C1、China has the largest population in the world, and about one fifth of the people in the world live in China.one fifth 是分数表达法。英文分数表达法：分子为基数词，分母为序数词，先读分子后读分母。当分子大于1时，分母的序数词则变为复数，直接在词

20、尾加“s”。eg: 四分之一 四分之三 二分之一 三分之二 2、one fifth of the people in the world live in China. 世界上五分之一的人口生活在中国。五分之一 写法是“_”, 分数做定语，与所修饰的名词之间加了一个_, of后的people是集体名词，所以live用的是_ (单数复数)。分数表达口诀：分子基数词，分母序数词，先读分子再读分母。分子大于一，分母用复数，直接在词尾加“s”练习：1) 1/7 one seventh 2) 2/5 two fifths 3) 3/4 _ 4) 8/9 _5) 1/ 4 one fourth 或 a qu
