1. China has the biggest population in the world.
中国是世界人口最多的国家。population意为“人口”时，是一个集合名词。它在句中作主语时，谓语动词通常用单数形
式。其常用句型为“The population of +某地+ is + 数词”或“某地+ has a population of + 数
词”，表示“某地有多少人口”。如：
The population of my city is three million.
◆ 当表示人口“多”或“少”时，常用形容词large，big或small修饰population。如：
The town has a large / big / small population.
◆ 当对人口数量进行提问时，要用疑问词what 或 how large。如：
What / How large is the population of your country?

(1) 这个国家人口少。
The country ___ _ _____ _________.
(2) 我的家乡有100万人口。

2. 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。
e.g. A: Can I use your bathroom? 我可以用一下你的卫生间吗？
B: Yes, feel free. 可以，请随意。
3. As far as I know, there are no other man-made objects as big as this.
据我所知，再没有像它这样大的人造物体了。
1) as far as I know是一个固定的表达方式，还可以说so far as I know, 意思是“据我所知”。
e.g. As far as I know, Jack’s got twin sisters. 就我所知，杰克有一对孪生姐妹。
They’re not coming today, so far as I know. 他们今天不来了– 就我所知是这样的。
2) 句中man-made是一个合
成形容词，意为“人造的”。像这样与-made复合而成的形容词不止一个。用以描述产品
的生产或制造手段，特点等，常见的有：
handmade—手工制作的 homemade—家庭制作的
machine-made—机制的 tailor-made—量体定制的；特制的；定做的
甚至还有像self-made (自学而成的；自我奋斗而成的；天然形成的)可以用来描述人。
