英语教案-The worlds population
(3)英语中无单独表示“万”和“亿”的量词,故用ten thousand表示“一万”,one hundred thousand 表示“十万”,twenty million表示“二千万”,three hundred million表示“三亿”。
因此,上面的数字就读成:three billion three hundred and thirty-three million three hundred and thirty-three thousand three hundred and thirty-three。
2.What’s the population of Germany? 德国的人口是多少?
population是个集合名词,意思是“人口;人数”,常用来指人口的总称,在日常使用时,必须注意以下几种用法:
(1)population是一个集合名词,在句中作主语时,谓语动词多用单数形式。如:
The population of Germany is about 81,000,000. 德国大约有八千一百万人口。
The worlds population is growing faster and faster. 世界人口增长越来越快。
注:如果population与分数或百分数连用时,谓语动词多用复数形式。如:
Three fifths of the population in our town are farmers. 我们镇五分之三的人是农民。
(2)表示“……的人口”可用the population of +地名,也可用the population in +地名,作主语中心词时,谓语动词用单数形式。如:
The population of Canada is 28,100,000. 加拿大人口是二千八百一十万。
(3)表示某国、某城市有多少人口时,还可用… have/has a population of…结构。如:
The city has a population of 50,000. 那座城市有五万人。
注:people常用于表示具体的人数,虽然people不加s,但谓语动词常用复数。如:
How many people are there in your family? 你家有几口人?
(4)由于population是不可数名词,因此不用How many也不用How much进行提问,应用What / How large。如:
1)Whats the population of China? 中国有多少人口?
2)澳大利亚有多少人?
误:How many is the population of Australia?
正:How large is the population of Australia?

(5)说明人口或人数的“多”或“少”时,不用many/few/much/little修饰,而用large, big或small, thin修饰。如:
Dalian has a large population. 大连人口很多。Which country has the smallest population Canada, the USA or Australia? 加拿大、美国、澳大利亚哪个国家的人口最少?
3. I wonder if that’s a lot of people for the size of the country. 我想知道这个国家能否容的下这么多人。
句中wonder的意思是want to know,常接if或whether引导的宾语从句。如:
I wonder if it is true. 我想知道这是不是真的。
I wonder whether Tom will come. 我不晓得汤姆来不来。
句中size 是名词,意思是“容量;尺寸;大小;面积”。如:
It was about the size of a duck’s egg. 其大小约如鸭蛋。
His shoes are Size 10. 他的鞋是十码的。
The earth is 49 times the size of the moon. 地球大约是月球的49倍。
4. Multiply this by 365. 用365来乘它(370,000)
(1)multiply A by B 用B乘A。
例:6 multiplied by 5 is 30. (6×5=30)6乘5等于30。
(2)“乘”的另外一种表达法是times。“除”在英语中用divide表示。
例:6 times 5 is (are) 30. 30 divided by 5 is 6.
