1、素材（含教案和练习）Module 11 Population一、学习目标：知识目标：能正确使用Module 11中的单词和短语；能力目标：能理解并用英语表述大数；正确使用冠词。情感目标：通过了解发展中国家所面临的问题，以及由此而产生的连带后果，唤起学生们的忧患意识，并引发他们深思。二、重点、难点：重点：1. 掌握短语along with, thanks to, add to, protectfrom的用法；2. 冠词的使用和英语大数的读法。 难点：1. add to和 addto, the number of和a number of的区别；2. too many, too much和much
2、too的用法；3. 正确使用冠词，准确用英语读出大数。三、知能提升（一）重点单词 单词学习 1. population 【用法】n. 人口（1）population是集体名词，没有复数形式，当它作主语，表示整体概念时，其后的谓语动词用单数。如表示个体概念，即人口的百分之几，几分之几作主语时，其后的谓语动词用复数。【例句】The population of the world is growing too fast. 世界人口增长过快。About 80 percent of the population of China are peasants. 中国约百分之八十的人口是农民。(2) 指人口的
3、“多”或“少”时，一般用large或small.【例句】The population of China is larger than that of the USA.中国人口比美国人口多。The population of Japan is much smaller. 日本的人口要少得多。（3）表示某国、某城市有多少人口时，要与of连用，其句式有两种：The population of +某国（某城市）+ is某国（某城市）has the/a population of。有时，“有多少人口的城市”用a city with a population of来表示。【例句】The populatio
4、n of Australia is 19,400,000. = Australia has a population of 19,400,000.Beijing is a city with a population of more than ten million. (4)提问“有多少人口”时，需用特殊疑问词what, 而不用how many 或how much。【例句】Whats the population of this city? 这个城市有多少人口？【考查点】人口的“多”或“少”的表达以及询问人口有多少的句式。【易错点】人口的“多”或“少”误用many或 few及用how many
5、 与population搭配。【考题链接】The experts think that Indias population may be _ than Chinas _ 2020.A. many, by B more, in C. larger, by 答案：C.解题思路：此题考查人口的“多”或“少”的表达，由于题目中有than，要用比较级，故先排除A；而指“人口多”时要用large, 故选C。2. increase【用法】v. 增加，增大 【例句】The number of students has increased.学生的人数增加了。注意：increase to 增加到 increase
6、 by 增加了来源:学科网【例句】The production of iron has increased to 120 million tons, which means that it has increased by 20%。铁的产量已增加到一亿两千万吨，意思是说它增加了20%。【考查点】increase to 和increase by的区别。 【易错点】错用介词。【考题链接】棉花的产量增加了10%。The cotton output has _ 10%.答案：increased by。解题思路：此题考查“增加了”的翻译，由于前面有has，所以increase要用其过去分词形式，故写为i
7、ncreased by。3. crowd【用法1】n. 人群用作名词时，其为集合名词。作主语时，其谓语用单数(视为整体时)或复数(考虑到个体成员时)均可。【例句】The crowd moves on, and no one tries to stop it. 人群向前移动，谁也没试图阻止。The crowd were running in all directions. 人群往四面八方跑去。强调人数多时，可用其复数形式。如：There were crowds of people waiting to get in. 有许多人在等着进去。【用法2】v. “聚集”、“挤满” 【例句】People
8、crowded round to get a better view. 人们争相围观。Shoppers crowded the streets. 买东西的人挤满了大街。常用结构 be crowded with【例句】The hall was crowded with people. 大厅挤满了人。The exhibition was crowded with visitors. 展览会挤满了参观的人。此外，派生形容词 crowded 意为“拥挤的”。如crowded trains (hotels, roads, shops) 拥挤的火车(旅馆，道路，商店)【考查点】crowd不同词性的用法。【
9、易错点】词性不同时意思不明确。【考题链接】When a bus comes, the _ at the bus-stop rushes and pushes to get on.A. people B. crowd C. police答案：B。解题思路：此题考查名词。由于句中所给谓语是rushes and pushes，用了单数，而people和police都是复数名词，其谓语要用复数，故选B。4. police【用法】n. 警察police是警察的统称，包括policemen和policewomen，一般用作复数，作主语时，其谓语要用复数。如要表示“一个警察”，则用a policeman 来
10、表达。【例句】The police are looking for the robber.警察（方）正在寻找盗贼。【考查点】词意理解。【易错点】作主语时谓语误用单数。【考题链接】The police _ searching for the thief everywhere.A. was B. are C. is答案：B。解题思路：此题考查police的用法，其作主语时，谓语要用复数，故选B。即学即练_ is the population of your city?

13、用法。由于 “A along with B ”这一结构作主语时, 谓语动词的数取决于A的数的变化，故选B。2. thanks to 【用法】“由于，多亏”（= because of）这一短语中，thanks是名词，to是介词。【例句】Thanks to the doctor, the boy was saved.多亏了医生，那男孩得救了。【考查点】短语本意。【易错点】误以为thanks是thank you的意思。【考题链接】_ the governments efforts, our life is becoming better and better.A.
