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。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”。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。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。Step 10 ExercisesStep 11 Homework1.

Even more serious difficulties include freezing weather conditions and heavy storms.1) Difficulty既可作可数名词也可作不可数名词，在此用作可数名词。做可数名词时，difficulty常用作复数，表示具体概念，即：各种各样的“困难; 难事; 难题”。例如：People learning a new language may face some difficulties.人们学习一门新的语言时可能会遇到一些困难。作不可数名词时，difficulty可译作“困难；艰难；辛苦；费劲”，例如：2) include表示“包括；包含”，是一个及物动词。例如：3. It is also very hard to take in air as you get near the top. It is + adj. + to do sth.， it作形式主语放在句首，而把真正的主语放在句尾。常用于此句型的形容词有important， difficult， dangerous， necessary， useful， possible等，用来对to do sth. 进行说明。此句型可以转换成To do sth. is + adj.。4.

The spirit of these climbers shows us that we should never give up trying to achieve our dreams. 1) give up意为“放弃”，后面可以接名词、代词或v-ing形式作宾语。 注意：如果其宾语是名词，那么名词可以放在give和up之间，也可以放在 up之后；如果其宾语是代词，那么代词只能放在 give和up之间。如：2) achieve our dream相当于make our dreams come true。6.
