population常与定冠词 the 连用,作主语用时,谓语动词常用第三人称单数形式。
e.g. The world’s population increasing is faster and faster.
全世界的人口增长得越来越快。
The population of China is about 1,300,000,000. 中国人口大约有13亿
当主语是表示“人口的百分之几、几分之几”时,谓语动词用复数形式。
e.g. About seventy percent of the population in China are farmers.
中国大约有百分之七十的人口是农民。
询问某国、某地有多少人口时, “How large... ”;在问具体人口时用“What... ”。
e.g. How large is the population of your hometown

What is the population of Canada
加拿大的人口数是多少
2. Qomolangma is 8,844.43 meters high.
It is … meters high (long, wide…). 它……米高(长,宽……)。
英语表示“有多长(宽，高……)”时，一般将数词和数量单位放在表示长宽高的形容词前作状语。

这座山三千多米高。
It is only 380,000 kilometers away.
离这里只有38万公里。

4. Feel free to ask me anything on today’s Great Wall tour.
在今天的长城游中，大家尽管问我任何问题，不要拘束。
feel free是英语口语中一个常用表达。若有人让你feel free to do something,就是让你无需拘束，只管按照自己的意愿去做某事。

—Yes, feel free.
5. As far as I know, there are no other man-made objects as big as this.

They’re not coming today, as far as I know.
据我所知，他们今天不会来。
6. Qomolangma is higher than any other mountain in the world.
(1).“any other +可数名词的单数”意为“任何其他的……”，指在同一范围内除了某人或某物以外的其他任何人或物。通常用于比较级，多用于同一范围内相比较。
e.g. Shanghai is bigger than any other city in China.
上海比中国任何一个城市都大。
(2)“any other +可数名词单数”可与 “the other +可数名词复数”互换，也可用最高级形式表示。
