population 是一个集体名词，作主语时，若指一个地区或国家的整体人口，谓语动词通常用单数；若强调整体人口中的成员，谓语动词通常用复数。
例如:The population of the city is about 20,000.
这个城市大约有两万人口。
Three fifths of the population here are old people.
这里五分之三的人是老年人。2) 表示一个地区或一个国家有多少人口时，可用 the population of ... is ... 或 ... has a population of ...。
例如：The population of our country is 28,100,000.
我们国家的人口是二千八百一十万。
The city has a population of 50,000.
这座城市有五万人口。形容“人口数量的多或少”可用large 或 small 修饰。
例如：The population of Beijing is large.
北京人口众多。3) 在询问人口时，要注意 population 和 people 的区别。前者通常用what来提问，后者用how many 来提问。
例如：
What’s the population of Canada?
加拿大的人口是多少？
How many people are there in the hall?
大厅里有多少人？e.g. Our factory is a big/large one.
我们的工厂很大。
（1）在表示物体重量、人的身高大或长大了时，
只能用big。
e.g. The box is too big to carry.
这个盒子太大，拿不了。
（2）在表示数量时，用large, 不用big。
e.g. A large number of people came from all
parts of the country to see the exhibition.
从全国各地来了很多人观看展览。3.big 和large都可表示具体事物形体或面积的大小, 往往可以互换?但big较口语化。E.g. There have been many great presidents in American history.
美国历史上有很多伟大的总统。
在表示抽象意思时, 有也可用big, 但great更为正式。
e.g. Great/Big changes have taken place in our country in recent years.
近几年来?我们国家发生了很大变化。great 的意思是“大、伟大的”?多用于抽象意思。
在修饰具体事物时?带有一定的感彩。huge指巨大的?往往指体积。
e.g. a huge stone, a huge building等。 4. That causes a lot of problems, such as too much traffic and noise.
too many 后面加可数名词，表示 “太多的”。
too much 后面加不可数名词，表示“太多的”。Babies born every minute in the world:
Babies born every year in the world:
Population of China:

5. The population of China is about 1.37 billion.

收获时刻Grammar Focus(二)冠词 Articles一.冠词的定义 冠词是一种虚词，没有词义，没有数和格的变化，不能单独使用，只能帮助名词或起名词作用的其他词类说明其意义。
冠词分定冠词和不定冠词两大类。定冠词特指一特定名词，不定冠词泛指一般普通名词。二.不定冠词的用法不定冠词有a和an两种形式，a用在以辅音开头的名词前，an用在以元音开头的名词前。它的用法如下：
1.表示“一个”的意思，与数词one相同。
例如：Rome was not built in a day.
罗马不是一天建成的；伟业非一日之功
The project(项目，计划) will be carried out（执行，贯策） in a year or two.2.表示一类人或事物。
例如：A dog is a faithful（忠诚的） animal.
Even a woman can do it.
3.表示“每一”，相当于per，用于某些表示时
间、重量、长度等单位前。
例如：He earns two thousand yuan a month.
The train is running sixty miles(英
里)an hour.
4.表示同样的人或事物，相当于the same。
例如：Birds of a feather（羽毛） flock (一群）together./They are people of a kind.
一群同样羽毛的鸟在一起/物以类聚,人以群分。 5.物质名词或抽象名词前用a 或an表示具体意义、制成品或种类。
例如：Green tea is a wonderful tea.
She is a beauty.（美人）
Please give me a coffee.
6.用于人名前，表示说话者对此人不认识，相当于“a certain”，也可指于某名人有类似性质的人或事物。
例如：A Mr. Chen came to see you this morning.
He wishes to become a Newton.7.有些世界上独一无二的东西，如sun, moon, sky, universe（宇宙）,world（世间，地球） ,earth （地球）等，一般前面要用定冠词，但当他们前面有修饰语时，则要用不定冠词。
例如：We hope we can see a full moon
tonight.
He sat in a chair, looking at a starry 布满星星的 sky.8. 在作单数可数名词定语的形容词最高级前，
如果不表示“最”，而表“非常”，则用不定冠词。例如：
That is a best dictionary.
This is a most troublesome（费事的） case.
（情形，情况)
9. 序数词前，一般有定冠词，但当表示“又一
个”时，则要用不定冠词。
例如：They have a second house.
When I sat down, a fifth man rose
(动词,rise的过去式 “站起来”）to speak.
10. 季节、月份、日期、三餐前有修饰语时，
用不定冠词。
例如：We had a wonderful lunch.
We had a very cold winter last year.
11. 用在某些固定的短语中
例如：once upon a time （从前) in a hurry
（匆匆忙忙）
have a rest have a good time
have a look all of a sudden （突然地）
have a cold/fever（发热）/cough/headache/
pain（疼痛）Homework Level A Learn the new vocabulary in unit 1
