Summary Language points: 1.One of the worlds most dangerous sports is mountain climbing, “one of + the + 形容詞的最高級(jí) + 復(fù)數(shù) 名詞”，意為“最之一”。如： Miss Wang is one of the most popular teachers in our school. 王老師是我們學(xué)校最受歡迎的老師之一。2. 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(shí)，difficulty常用作復(fù)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(xué)習(xí)一門新的語言時(shí)可能會(huì)遇到一些困難。 作不可數(shù)名詞時(shí)，difficulty可譯作“困難；艱難；辛苦；費(fèi)勁”，例如：He had great difficulty in finding a new job.他找新的工作費(fèi)了很大勁。We found the house without difficulty.我們輕而易舉的找到了那座房子。2) include表示“包括；包含”，是一個(gè)及 物動(dòng)詞。例如：Does your price of the bike include this light?你們的車價(jià)包含這盞車燈嗎？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(duì)to do sth.進(jìn)行說明。此句型可以轉(zhuǎn)換成To do sth. is + adj.。e.g. It is important to study English well. 學(xué)好英語很困難。 Its very difficult to climb Qomolangma. 攀登珠穆朗瑪峰很難。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：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. 雖然英語不易學(xué)，但我不會(huì)放棄。 2) achieve our dream相當(dāng)于make our dreams come true，其中動(dòng)詞achieve表示“(通過努力) 實(shí)現(xiàn)；取得；獲?。贿_(dá)到(夢(mèng)想、成績(jī)、成功、目的)”等。例如：. He achieved great success in a short time. 他用很短的時(shí)間取得了極大的成功。 Lin Tao achieved very good exam results. 林濤考試取得了很好的成績(jī)。5. 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(dāng)于even if，引導(dǎo)讓步狀語從句，一般不與并列連詞but連用。如： Mr. Wang will come on time even though it rains. 盡管下雨，但王老師會(huì)按時(shí)來。Step7 ExercisesComplete the sentences using the information in the forms.the Nile the Yangtze River the Yellow River 6,671km 6,300km 5,500km The Yellow River is long.The Yangtze River is a lot _ than the Yellow River.The Nile is _ of all.The Yangtze River is not _ long _ the Nile.= The Yangtze River is not _ than the Nile.Qomolangma Mount Huang Mount Tai 8,848m
