Step 9 Language points and summary1. China has the biggest population in the world. 中國是世界人口最多的國家。population意為“人口”時，是一個集合名詞。它在句中作主語時，謂語動詞通常用單數(shù)形式。其常用句型為“The population of +某地+ is + 數(shù)詞”或“某地+ has a population of + 數(shù)詞”，表示“某地有多少人口”。如：The population of my city is three million. 當表示人口“多”或“少”時，常用形容詞large，big或small修飾population。如：The town has a large / big / small population. 當對人口數(shù)量進行提問時，要用疑問詞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. 在今天的長城游中，大家盡管問我任何問題，不要拘束。feel free是英語口語中一個常用表達。若有人讓你feel free to do something, 就是讓你無需拘束，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. 據(jù)我所知，再沒有像它這樣大的人造物體了。1) as far as I know是一個固定的表達方式，還可以說so far as I know, 意思是“據(jù)我所知”。2) 句中man-made是一個合成形容詞，意為“人造的”。像這樣與-made復合而成的形容詞不止一個。用以描述產(chǎn)品的生產(chǎn)或制造手段，特點等。甚至還有像self-made (自學而成的；自我奮斗而成的；天然形成的)可以用來描述人。Step 10 ExercisesStep 11 Homework1.

Even more serious difficulties include freezing weather conditions and heavy storms.1) Difficulty既可作可數(shù)名詞也可作不可數(shù)名詞，在此用作可數(shù)名詞。做可數(shù)名詞時，difficulty常用作復數(shù)，表示具體概念，即：各種各樣的“困難; 難事; 難題”。例如：People learning a new language may face some difficulties.人們學習一門新的語言時可能會遇到一些困難。作不可數(shù)名詞時，difficulty可譯作“困難；艱難；辛苦；費勁”，例如：2) include表示“包括；包含”，是一個及物動詞。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作形式主語放在句首，而把真正的主語放在句尾。常用于此句型的形容詞有important， difficult， dangerous， necessary， useful， possible等，用來對to do sth. 進行說明。此句型可以轉(zhuǎn)換成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意為“放棄”，后面可以接名詞、代詞或v-ing形式作賓語。 注意：如果其賓語是名詞，那么名詞可以放在give和up之間，也可以放在 up之后；如果其賓語是代詞，那么代詞只能放在 give和up之間。如：2) achieve our dream相當于make our dreams come true。6. Why do so many people try to climb this mountain even though it is dangerous?even though 用作從屬連詞，意為“即使；盡管”，相當于even if，引導讓步狀語從句，一般不與并列連詞but連用。Step 7 HomeworkRetell the article, and then preview the Grammar focus. 板書設(shè)計教學反思備課組長意見1. the most dangerous mountain 2. one of the worlds most dangerous sports 3. mountain climbing/climb mountains4. the climbers from all over the world 5. run along the southwestern part of China 6. of all the mountains 7. thick clouds 8. more serious difficulties9. freezing weather conditions and heavy storms 10. the first people to reach the top of Qomolangma 教研組長意見 Section A 3 (Grammar focus - 4c)Step 1 Revision Ask the Ss to retell the article.Step 2 Grammar focusStep 3 Grammar我們已經(jīng)學習過形容詞和副詞的比較級和最高級的構(gòu)成及基本用法。下面我們進一步學習與其相關(guān)的其他知識點。形容詞和副詞比較級的修飾語1. 比較級前可加much, a lot, a bit, a little, any, no, some, even, still等詞修飾。如：2. 比較級前還可加其他表示數(shù)量的詞。如：形容詞和副詞最高級的其他用法1. 形容詞最高級可被second, third等序數(shù)詞修飾。如：2. 形容詞最高級常用于句型“one of +the+形容詞最高級 + 可數(shù)名詞的復數(shù)形式”，意為“最之一”。3. 形容詞和副詞的比較級和最高級可以互相轉(zhuǎn)換。如： Jane is taller than the other girls / any other girl in the club. = Jane is the tallest girl in the club.
