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?【运用】完成句子，每空一词。(1) 这个国家人口少。The country _ _ _ _. (2) 我的家乡有100万人口。My hometown _ _ _ _ one million. (3) 北京有多少人口？_ _ _ _ _ Beijing? 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 ing 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。Step 10 ExercisesStep 11 Homework1.

Answers: dangerous, climbing, popular, risks, climbers, famous, runs, southwestern, highest, famous, the hardest, cover, difficulties, weather, heavy, people, reached, womanStep 5 Language points1. One of the worlds most dangerous sports is mountain climbing, “one of + the + 形容词的最高级 + 复数名词”，意为“最之一”。如： Miss Wang is one of the most popular teachers in our school.王老师是我们学校最受欢迎的老师之一。2. 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：He had great difficulty in finding a new job.他找新的工作费了很大劲。We found the house without difficulty.我们轻而易举的找到了那座房子。2) include表示“包括；包含”，是一个及物动词。例如：Does your price of the bike include this light?你们的车价包含这盏车灯吗？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.。e.g. It is important to study English well. 学好英语很重要。 Its very difficult to climb Qomolangma. 攀登珠穆朗玛峰很难。4. The first Chinese team did so in 1960, while the first woman to succeed was Junko Tabei from Japan in 1975.succeed作动词，意为“实现目标；成功”，succeed in doing sth.意为“成功地做某事”。如：The climber succeeded in reaching the top of the mountain. 登山者成功登到了山顶。5. 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：My uncle wants to give up drinking wine. 我叔叔想戒酒。Although English isnt easy to learn, I wont give it up. 虽然英语不易学，但我不会放弃。2) achieve our dream相当于make our dreams e true。6. Why do so many people try to climb this mountain even though it is dangerous?even though 用作从属连词，意为“即使；尽管”，相当于even if，引导让步状语从句，一般不与并列连词but连用。如：Mr. Wang will e on time even though it rains.尽管下雨，但王老师会按时来。Step 6 Exercises根据句意及所给汉语提示，写出句中所缺单词。1. We try to celebrate the _ (成就) of those great scientists.2. He wanted to reach the top of the mountain and he _ (成功). 3. I have a small house. It _ (包括) a bedroom, a kitchen and a bathroom.4. You should work hard to _ (实现) your dream.5. If you go to the poor village, you will be shocked by the living _ (条件).Step 7 HomeworkRetell the article, and then preview the Grammar focus.
