Unit 7 What’s the highest mountain in the world?Section B & Self Check教材知識全解 講透知識 查漏補缺知識點一 die from的用法教材原文The babies often die from illnesses and do not live very long.那些幼崽經(jīng)常死于疾病,活不了太長時間.本句中的die from是固定搭配,意為“死于”.The old man died from/of colon cancer.這位老人死于結(jié)腸癌.辨析die from若死因不存在于人體之內(nèi)或之上,而是由環(huán)境造成的(主要指事故等方面的外部原因),一般用介詞 from.如:die from an earthquake/a traffic accident/a lightning 死于地震／交通事故／雷擊die of若死因存在于人體之上或之內(nèi)(主要指疾病、衰老等自身的原因),一般用介詞of.如:die of illness/heart trouble/cancer/a fever 死于疾病／心臟?。┌Y／發(fā)燒若死因是環(huán)境影響到體內(nèi),即兩方面共有的原因,則用of或from均可.如:die of/from a drink/a wound/overwork/starvation/hunger and cold死于飲酒／受傷／勞累過度／饑餓／饑寒.但是在實際運用中,兩者混用的情況較多.例1-Some of the animals__________ the pollution.-Right. The government will find ways to solve the problem.A. die toB. die inC. die onD. die from解析 若死因存在于人體之上或之內(nèi)(主要指疾病、衰老等自身的原因),一般用介詞of;若死因不存在于人體之內(nèi)或之上,而是由環(huán)境造成的(主要指事故等方面的外部原因),一般用介詞from,故選D.答案 D知識點二 cut down的用法教材原文 Many years ago, there were a lot more bamboo forests and pandas in China, but then humans started to cut down these forests.許多年前,中國有更多的竹林和熊貓,但是后來人類開始砍伐這些竹林.cut down是固定搭配,在此處意為“砍伐;砍倒”.cut down還可以表示“減少;縮短”.They are cutting down the trees.他們正在砍伐樹木.Seven trees have been cut down.七棵樹已經(jīng)被砍倒了.拓展“動詞＋down”的短語小結(jié):look down 向下看cut down 砍伐turn down關(guān)小;調(diào)低lie down 躺下pull down 拆毀write down寫下break down出故障put down 放下:寫下例2 (2020安徽阜陽太和三校聯(lián)考)-Do not__________ the big tree that gives you shade.-Er, I agree with you.A. turn downB. cut downC. take downD. sit down解析句意:-不要砍了那棵能給你遮陰的大樹.-嗯,我同意你的說法.turn down“關(guān)小”;cut down“砍倒;減少”;take down“拆除”;sit down“坐下”.由句意可知B項符合題意.答案 B 重點難點全解 精講精解 精準(zhǔn)高效如何表達較大的數(shù)字概念本單元側(cè)重講“千位數(shù)及以上的數(shù)字概念”.具體如下:從數(shù)字的右端向左端數(shù),每三位數(shù)加一個千分撇“,”.從右開始,第一個“,”前的數(shù)字后添加thousand;第二個“,”前面的數(shù)字后添加million;第三個“,”前的數(shù)字后添加billion.然后一節(jié)一節(jié)分別表示,兩個逗號之間最大的數(shù)為百位數(shù)形式.2,648 two thousand six hundred and forty-eight16,250,064 sixteen million two hundred and fifty thousand sixty-four5,237,166,234 five billion two hundred and thirty-seven million one hundred and sixty-six thousand two hundred and thirty-four 單元語法全解 熟患句型 把握要領(lǐng)形容詞、副詞的比較級和最高級英語中,在兩者之間進行比較時,要用比較級;在三者或三者以上的人或物之間進行比較時,要用最高級.關(guān)于比較級和最高級的構(gòu)成和句式如下:1.比較級和最高級的構(gòu)成(1)規(guī)則變化單音節(jié)詞和少數(shù)雙音節(jié)詞一般在詞尾加-er, -estlong-longer-longest以不發(fā)音的e結(jié)尾的,加-r,-stnice-nicer-nicest以“輔音字母＋y”結(jié)尾的,變y為i,再加-er, -estearly-earlier-earliest以重讀閉音節(jié)結(jié)尾且詞尾只有一個輔音字母時,雙寫該輔音字母,再加-er, -estfat-fatter-fattest多音節(jié)詞和部分雙音節(jié)詞借助more構(gòu)成比較級,借助most構(gòu)成最高級 difficult-more difficult- most difficult(2)不規(guī)則變化一些形容詞和副詞的比較級和最高級是不規(guī)則變化.常見的此類詞有:原級比較級最高級bad/illworseworstmany/muchmoremostgood/wellbetterbestfarfarther/furtherfarthest/furthestoldolder/elderoldest/eldestlittlelessleast記憶口訣“壞”“病”兩“多”和兩“好”.一是“遠”來二是“老”.little是“少”不是“小”.2.和比較級有關(guān)的句式…比較級＋than...比······更······The+比較級...,the+比較級...越······,就越······比較級＋and+比較級越來越······Who/Which...比較級,A or B?誰／哪一個更······,A還是B?Our house is smaller than yours, but I think the garden is bigger.我們的房子比你們的小,但我認(rèn)為花園比較大.The busier he is, the happier he feels.他越忙,就越開心.It's getting warmer and warmer.天氣正變得越來越暖和.Who is taller, Lisa or her sister?誰更高,莉薩還是她姐姐?注意 如果比較級要借助more來構(gòu)成,則“越來越······”要用“more and more+原級”結(jié)構(gòu).Our city is becoming more and more beautiful.我們的城市正變得越來越美麗.3.和最高級有關(guān)的句式...最高級...＋in/of短語······中最······的······one of the+最高級＋可數(shù)名詞復(fù)數(shù)形式最……的……之一Who/Which...最高級,A,B or C?誰／哪一個最······,A、B還是C?She is the most beautiful girl in her class.她是她班里最漂亮的女孩.Shanghai is one of the biggest cities in the world.上海是世界上最大的城市之一.Which do you like best, tea, coffee or juice?你最喜歡哪個,茶、咖啡還是果汁? 易錯易混全解 對比辨析 跳出陷阱include, including, includedinclude用作及物動詞,意為“包括;包含”including用作介詞,意為“包括······在內(nèi)”included用在名詞或代詞后,意為“包括······在內(nèi)”Your duties will include putting the children to bed.你的職責(zé)包括讓孩子們上床睡覺.Ten members were present at the meeting, including me.10個成員出席了會議,包括我在內(nèi).Everyone laughed, me included.每個人都笑了,包括我在內(nèi).
