課題名稱形容詞和副詞（二）教學目標同步教學知識內容形容詞和副詞，as + 形容詞或副詞原級 + as；比較級形容詞或者副詞 + than；可修飾比較級的詞個性化學習問題解決形容詞的比較級教學重點as + 形容詞或副詞原級 + as；比較級形容詞或副詞 + than；可修飾比較級的詞教學難點比較級的運用教學內容一、比較級基本句型 表示兩者(人或物)比較時，相比較的對象應是同類事物，不同類的事物無法比較，我們常用以下句型：1） AB或AB（比較級+than） This room is smaller than that one. This story is more interesting than that one. 2） A=B（as+原級+as） This cake is as big as that one. Swimming is as exciting as climbing.3） A B ( not as/so+原級+as 與不一樣,more+原級 超過) Jim is not as/so tall as Li Lei. John is more hard-working than Joan. English is more useful than Japanese. = Japanese is not so/as useful as English.二、形容詞，副詞的比較級中，asas，soas的用法 as + 形容詞或副詞原級 + as1）在否定句或疑問句中可用so as。 He cannot run so/as fast as you.2）當as as 中間有名詞時采用以下格式。 as +形容詞+ a +單數名詞 as + many/much +名詞 This is as good an example as the other is. I can carry as much paper as you can.3）用表示倍數的詞或其他程度副詞做修飾語時，放在as的前面。 This room is twice as big as that one. Your room is the same size as mine.4) 倍數+ as + 形容詞 + as= 倍數+ the+名詞 + of+其它 This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine.三、 使用比較級需注意的事項1）要避免重復使用比較級。 (錯) He is more cleverer than his brother. (對) He is more clever than his brother. (對) He is clever than his brother.2）要避免將主語含在比較對象中。 (錯) China is larger that any country in Asia. (對) China is larger than any other countries in Asia.3）要注意對應句型，遵循前后一致的原則。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out.4）要注意冠詞的使用，后有名詞的時候，前面才有可能有冠詞。比較：Which is larger, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters.可修飾比較級的詞1）a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even2）還可以用表示倍數的詞或度量名詞作修飾語。3）以上詞(除by far)外，必須置于比較級形容詞或副詞的前面。典型例題:1）- Are you feeling _? - Yes，Im fine now.A. any wellB. any betterC. quite good D. quite better答案：B. any 可修飾比較級，quite修飾原級，well的比較級為better.2）The experiment was_ easier than we had expected. A.more B.much more C.much D.more much 答案：C.much可修飾比較級，因此B，C都說得通，但easier本身已是比 較級，不需more，因此C為正確答案。3）If there were no examinations, we should have _ at school.
