The World Is a Big PlacePPT，第二部分内容：课堂互动探究

词汇点睛 

increase v.  增加；增大

[观察] It is increasing very quickly.

它(世界人口)正在非常迅速地增长。

Reading can increase your knowledge. 阅读可以增长你的知识。

[探究] increase意为“增加，增大”，可用作及物动词，也可用作不及物动词。用作及物动词时，常接名词作________。

1　And by 2050, the world's population may reach 9 billion.

并且截止到2050年，世界人口可能将达到90亿。

[探究] (1) “by＋时间”表示“到……为止；不迟于……”。根据不同的时间，使用不同的________。

(2)billion 意为“十亿”，前面有________数字时，用单数形式；后面加________表示概数时，用________形式。例如：

two billion 20亿　billions of  数十亿

[拓展]与 billion 用法相同的词还有hundred(百), thousand(千), million(百万)。

2　We can't live in water, and only about one third of our planet is land. 我们不能居住在水里，而我们的星球只有三分之一的面积是陆地。

[探究] one third of our planet意为“我们星球的三分之一”，one third表示分数1/3。英语中的分数用数词来表示：分子用基数词，分母用序数词。如果分子大于1，则分母用复数形式。分子和分母中间可加连词符，也可不加。表示“一半”时，常用half。例如：2/7 two sevenths(two­-sevenths)　1/2 one half

[拓展] 分数修饰名词作主语时，谓语动词的单复数要根据分数所修饰的名词的单复数来定。

Three fourths of the money has been spent on books.

四分之三的钱用来买书了。

Two thirds of the students in my class are boys.

我们班里三分之二的学生是男孩。

3　It must be treated well for our children and for our children's children, too! 

为了我们的孩子，也为了我们孩子的孩子，一定要好好地对待它！

[探究] must be treated为含有情态动词的被动语态形式。含有情态动词的被动语态构成形式为“情态动词＋be＋________________”。例如：

The trees should be treated well.树木应该被好好地对待。

An art school may be opened next year.

明年可能开办一所艺术学校。

This book must not be removed from the library.本书不得带出图书馆。

She might be sent to work abroad.她可能被派往国外工作。
