Language points
1. population
population意為“人口數(shù)量”，謂語動詞要用單數(shù)形式。詢問人口數(shù)量時要用“What’s the population of ...?”提問，而不用how many或how much等提問。表示人口“多”要用large 或 big；表示人口“少”要用small。
這個城市的人口是600萬。
The population of this city is six million．
中國的人口比美國的人口多很多。

2. man-made
為合成形容詞，意為“人造的”。英語中像這樣與-made復合而成的形容詞還有：handmade(手工制作的)、homemade (家庭制作的)、machine-made (機制的)等，用以描述產(chǎn)品的生產(chǎn)或制造手段、特點等。
這種魚都是自家做的。

3. Feel free to ask me anything on today’s Great Wall tour.

A: Can I use your computer?
我可以用一下你的電腦嗎？
B: Yes, feel free.可以，請隨意。
4. As far as I know, there are no man-made objects as big as this.
據(jù)我所知，再沒有像它這樣大的人造物體了。

說so far as I know，意思是“據(jù)我所知”。

5. Qomolangma is 8,848.86 meters high.
It is … meters high (long, wide…).
它……米高(長,寬……)。
英語表示“有多長(寬，高……)”時，一般將數(shù)詞和數(shù)量單位放在表示長寬高的形容詞前作狀語。
這座山高三千多米。
The mountain is more than three thousand meters high.
它離我們只有三十八萬公里。
It is only 380,000 kilometers away.
這座綠色長城長7,000公里。
