重点词句精讲
1. population
population意为“人口”时，是一个集体名词，被看作一个整体，在句中做主语时，后面的谓语动词用单数形式。例如：
The population ofChinais large.中国人口众多。
【拓展】
(1) 当表示一个城市、地区或国家有多少人口时，常用以下两种结构，即“the population of + 某地 + is + 数词”或“某地 + has a population of + 数词”。例如：
The population of London is over ten million. =
London has a population of over ten million. 伦敦的人口超过一千万。
(2) population可与large，small搭配，但不能与many，few搭配。例如：
The city with its large population has become crowded.
这个人口众多的城市变得拥挤不堪了。
(3) 询问人口数量常用what或how large。例如：
What’s the population of the city =
How large is the population of the city
这个城市有多少人口？

【拓展】
including除了是include的现在分词/动名词之外，在日常运用中一般被当作介词使用，和其后的名词/代词一起形成介宾短语，意思是“包括……在内”。
例如：There are many different kinds of moon cakes, including fruit, coffee and ham.有很多种月饼，包括水果的，咖啡的和火腿月饼。
There are 40 students in the classroom, including me.
班里有40名学生，包括我在内。
同样，included也有介词用法，且：including + 宾语 = 宾语 + included。
所以上个例句亦可写成：There are 40 students in the classroom, me included.

His plan succeeded.他的计划成功了。

The law should remain in force.法律应当有效力。

(2)force作动词，意为“强迫”。force sb. to do sth.意为“强迫某人做某事”

他们是按重量收取运费吗
It’s smaller in size but greater in weight.
它体积比较小，但分量比较重。
8. take in
take in意为“吸入；吞入（体内）”。例如：
On weekends the Smiths usually drive to the countryside and take in the fresh air there.周末，史密斯一家常驱车到农村去呼吸那里的新鲜空气

那个可怜的人没有地方住，所以我们让他住在我家。
9. As far as I know, there are no man-made objects as big as this.
as far as I know是一个固定表达方式，还可以说so far as I know，意为“据我所知”。
例如：

据我所知，王涛有俩弟弟。
They’re not coming this Sunday, so far as I know.
他们这周日不来了——就我所知是这样的。
10. This spirit of these climbers shows us that we should never give up trying to achieve our dreams.

【拓展】

give off放出，释放；
give in屈服，让步；
give out分发，用完；
give back归还
11. Scientists say there are now fewer than 2,000 pandas living in the remaining forests.
本句中living in the remaining forests为现在分词短语，修饰名词pandas。
分词短语作定语时，应置于被修饰名词之后。例如：
The man standing by the window is our teacher.
站在窗边的那个人是我们老师。
（standing by the window就是一短语，也就是说不是一个单词，在此作定语表主动）
Suddenly there appeared a young woman dressed in green.
突然出现一个穿绿色衣服的女青年。
【注意】现在分词作定语表示动作正在发生或与谓语动作同时（或基本同时）发生，表示主动意义；
及物动词的过去分词作定语表完成或被动的动作；不及物动词的过去分词作定语只表完成不表被动的动作。例如：
They lived in the house facing the south.
他们住在朝南的房子里。(现在分词作定语表示主动意义)
The meeting held yesterday is important.
昨天开的会议很重要。（及物动词的过去分词表被动或完成）
(2)分词短语作定语相当于一个定语从句，修饰前面的名词。例如：
The man reading a novel at the desk is my father.（现在分词表“主动、正在”）
= The man who is reading a novel at the desk is my father.
在桌边读小说的人是我父亲。
Is there anything planned for tonight （过去分词表“被动、已经”）
= Is there anything that has been planned for tonight
今晚有什么活动吗？

【拓展】(1)“every other+单数名词”意为“每隔一……”。例如：
every other day 每隔一天 every other tree 每隔一棵树
(2)“every few+复数名词”意为“每隔几……”。
例如：every few days每隔几天
13. One of the world’s most dangerous sports is mountain climbing…

How to Protect Wild Animals
Many wild animals are in danger because their living environment has changed a lot. Humans cut down trees and the environment is polluted seriously, so the wild animals have fewer and fewer places to live in. At the same time, some people kill them for their fur, skin, teeth or meat.
As we all know, animals are our friends, so it’s our duty to protect them. We can plant more trees to make homes for them and make laws to stop them from being killed.
Let’s work together to protect the wild animals.

Dear classmates,
Elephants are one of the largest animals on land. They can live up to 80 years. However, these days the number of elephants is becoming smaller and smaller. Because people cut down forests, they are losing their homes. People also kill them for their ivory. Elephants are in great danger now. I think we should try our best to protect them. First, we are supposed to help make rules to stop people from killing elephants. Second, we should plant more trees to help them build their homes. Third, we’d better not buy anything made of ivory.
After all, animals are our friends. Let’s take action to protect them.
Yours,
Gina
