Step 9 Language points and summary1. 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?2. Feel free to ask me anything on todays 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, Jacks got twin sisters. 就我所知，杰克有一对孪生姐妹。 Theyre 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
