2能力目标

3.情感目标

【重点难点】

掌握本课词汇和句型

掌握大额数字的读法

能够就人口问题展开讨论，提出解决办法。

【知识解析】

一． 数字的写法; 在英语中，三位数以内的数字直接写，超过三位数的每隔三位用逗号隔开，如;500 1,500 11,500 111,500 1,111,500 依此类推。

二．数字的读法 ●1.数字的单位：hundred 百thousand 千million百万 billion 十亿 trillion万亿

●2.一位数或两位数：直接按单词的读法读

●3.三位数：通常需要在百位后加上and（整百除外）如：120 one hundred and twenty

102 one hundred and two 200 two hundred

●4.三位以上：三位一节，从右往左，第一个逗号之后加上thousand，第二个逗号之后加上million，第三个逗号之后加上billion ，第四个逗号之后加上trillion，如 ●1,245 one thousand ,two hundred and twenty;

●12,345 twelve thousand,three hundred and forty- five .10,001 ten thousand and one

●100,941 one hundred thousand ,nine hundred and forty- one

●2 ,134,658 two million ,one hundred and thirty-four thousand ,six hundred and fifty- eight ●31,234,567,890 thirty-one billion ,two hundred and thirty-four million ,five hundred and sixty-seven thousand ,eight hundred and ninety.

注意：

●1，英语中没有“万”，十万，千万，亿等单位，要表示这些概念时应用英语中有的数字单位进行换算，如:万即十个千（ten thousand），十万即百个千(one hundred thousand)，千万即十个百万(ten million)，亿即百个百万(one hundred million)

●2, 表示具体数字时，数字单位（hundred，thousand ,million ,billion,trillion）之后不能加s表示复数，但泛指很多时，可以在单位后加s，形成短语hundreds of（数百的，成百上千的）,thousands of（大量的，成千上万的） ,millions of（数百万的） ,billions of（数十亿的）,这些短语前不能加数字，只是表示泛指。

三，prepare….for…为了…..准备好…,也可直接说prepare for….为….作准备

如：We prepared a big birthday cake for her birthday.我们为她的生日准备了一个很大的生日蛋糕。Now I’m going to prepare for the final exam.现在，我得开始准备期末考试了。

四，辨析so much 和so many。俩者均表示：如此多的….，但前者修饰不可数名名词，后者修饰可数名词。如：I’m sorry to hear that you have so much trouble.

.我很抱歉你有这麽多的麻烦事。

Oh,you have so many books.! 哦，你有那么多书。

1

五，make notes,做笔记， 如：You shoud make more notes in English lessons.你在英语课上应该多做笔记。 六，one fifth :五分之一

●1,分数的表达方式：基数词+序数词，其中基数词表示分子，序数词表示分母。当分子大于1时，分母用复数形式，如：Tow fifths of the students are from the city.五分之二的学生来自于这个城市。 ●2,需要注意的是：1/2不能说a(one ) second,而要说a(one )half.1/4和 3/4可以说a(one)fourth three fourths,但常用a quarter和three quarters表示。如： One harf of my friends went abroad.我有一半的朋友都出国了。

●3，分数修饰名词时作主语时，谓语动词与分数所修饰的名词一致，如：Only one fifth of air consists of

oxygen. 氧气只占空气的五分之一。 About two thirds of the students are boys.大约三分之二的学生是男孩。

●4，带分数也是常见的英语数词表达：整数部分要和分数部分要用and连接,当带分数修饰名词时，该名词通常是复数。如：You should finish the work within one and a fourth hours.

你应该在1.25小时之内完成这项工作。

【笔记详解】 1. The population of China is about 1.37billion.
