初中英語比較級的使用.doc

初中生在學(xué)習(xí)英語中，經(jīng)常會感到形容詞（副詞）的比較級難以掌握，主要是因為比較級的用法相當(dāng)靈活，應(yīng)用范圍比較廣，出現(xiàn)頻率比較高，加之比較級在某種情況下可以和原級、最高級互相轉(zhuǎn)換，同學(xué)們更不能小覷。下面，我將根據(jù)“比較級”常見的句型，簡單地列舉七大類型，并輔以例句加以闡釋，以便于同學(xué)們輕松地學(xué)習(xí)，愉快的接受。一、 用于兩者之間的比較，常見的句型為1 A + 謂語 + 比較級 + than + B.例如： My shoes are bigger than hers.(我的鞋子比她的大。) Sandy eats more quickly than Tom. (仙蒂吃的比湯姆快。) The weather in Nanjing is hotter than that in Beijing in summer. (夏季，南京的天氣比北京熱。)特別提醒的是：A和B所比較的內(nèi)容一定是相同的。再如： My friend Tom never eats junk food, and he is_(健康地) than me. Amy makes fewer mistakes than Frank. She does her homework _.A. more carefully B. more carelesslyC. more careful D. more careless解析 根據(jù)than可以判定應(yīng)該填入形容詞的比較級，healthier或者more healthy。 根據(jù)前句判斷該題應(yīng)該選擇副詞的比較級，故選A。例如 Which coat is _ on me, the blue one or the black one?A. good B. better C. best D. the bestWhich city is _ (far) to the sea, Beijing or Tianjing?解析 根據(jù)上述結(jié)構(gòu)，應(yīng)該選擇形容詞的比較級，故B為正確答案。 根據(jù)提議，兩者比較，該題應(yīng)用形容詞的比較級，正確答案為：farther 。當(dāng)然，在某種情境下，比較級和原級之間的可以轉(zhuǎn)換。例如：she doesnt run so fast as her brother.（她不如她哥哥跑得快。）=Her brother runs faster than she.(她哥哥跑得比她快。)再如Dont just believe the advertisement. This kind of camera is _ it says.A. as good as B. not as good asC. as well as D. not as well as解析根據(jù)前句的意思，可以判定本題為形容詞的阮籍，整個句子是否定的含義，故B為正確答案。二、 用于多于兩者之間的比較，常見的為：A+謂語+比較級 + than + any / any other/ the other 句型例如1. China is larger than any country in Africa. (中國比非洲的任何一個國家都大。)2. China is larger than the other countries in Asia. = China is larger than any other country in Asia. = China is larger than the others in Asia. (在亞洲中國比其他國家都大。)3. Tom is taller than the rest of the boys in his class. (湯姆比班的其他城市都多。)4. The city Beijing has a larger population than any other city in the north of China. （北京市的人口比中國北方任何一個其他城市都多。）在某種情況下，比較級和最高級之間可以相互轉(zhuǎn)換。例如1. China is larger than the other countries in Asia. = China is the largest in Asia.2. Tom is taller than the rest of the boys in his class.= Tom is the tallest in his class.三、 用于“冠詞+比較級+修飾語”句型1. 比較級后接名詞時，比較級前面如果用冠詞，此時冠詞不是修飾比較級，而是修飾后面的名詞。例如：Whom would you like to be your assistant, Jack or David?If I had to choose, David would be _ choice.A. good B. better C. the better D. the best解析根據(jù)題意，兩者之間比較應(yīng)用比較級，后面有修飾的名詞，所以選擇C。2. 要特質(zhì)兩者中“更，較”時，比較級前面通常帶定冠詞，此時比較級后面省略了相關(guān)的名詞或者帶刺，定冠詞實質(zhì)是修飾被省略的名詞或代詞。例如This vase is the heavier of the two.Of the twins , Lily is the shorter.3. 用于“the +比較級，the +比較級”中，表示“越越”例如The busier he is, the _ he feels.A. happily B. happy C. happier D. more happyAs middle school students, we should study hard for the future. I think so._ we study now, _ future well have.A. the hard; the goodB. the harder; the betterC. the hardest ; the best.解析根據(jù)題意本題應(yīng)該選用形容詞的比較級，故選擇C本題符合上述的結(jié)構(gòu)，故B為正確答案。四、用在一些修飾詞后面。常見的修飾詞有far, much, even, still, a little, rather, any, no, very much, three times等.。例如1. Now telephones are very popular and they are much _ than before.A. cheap B. cheaper C. cheapest D. the cheapest2. Mr. Smith, would you please speak a little more_ ?Sorry! I thought you could follow me.A. quietly B. quickly C. slowly D. politely 3. The drivers had to drive slowly and carefully as it got much _(fog).解析1.根據(jù)題意，本題應(yīng)該選用形容詞的比較級，應(yīng)選擇B2.根據(jù)上句的敘述，本題應(yīng)該選擇副詞的比較級，符合句意的選項為C。3. 本題填寫形容詞的比較級，為foggier、。五、用于“比較級+and +比較級”中，表示“越來越”例如1. I love Urumqi because it is becoming _.A. more and more beautiful B. beautiful and beautiful C. clean and clean D. MORE AND MORE CLEAN2.some big cities are becoming more and more _(擁擠的) and polluted.3. the number of giant panda is getting _ because their living areas are becoming farm lands.A. less and less B. larger and largerC. smaller and smaller D. fewer and fewer解析1.根據(jù)題意，這里應(yīng)該選擇形容詞的比較級，A為正確選項。2. 用在 more and more 后面的應(yīng)該是形容詞的原級，答案為crowed。3. 根據(jù)題意及關(guān)鍵詞number， 確定答案為C.六、用于no one/ none 之類的否定句型中“no +比較級+than”結(jié)構(gòu)，一位“都不”，He is no clever than i.而“no +比較級+than”結(jié)構(gòu)，譯為不及，my dress is not better than yours.值得一體的是，這種特殊的比較級結(jié)構(gòu)優(yōu)勢會表示最高級的意思。例如1. I have never heard a better voice than yours = your voice is the best voice that I have ever heard.2. none of us is slimmer than her = She is the slimmest of us 3. nothing is more important than this.= this is the most important thing of all.再如1. No one speaks French _ him. So he can be a TV host of French programmerA. as beautiful as B. as badly asC. worse than D. better than 2. Anns house is ten miles away from the school and nobody else in her class lives _.A.far B. farther C. farthest D. the futhest3.
