八年級英語上冊 Unit 3 I’m more outgoing than my sister（第3課時）Section A（Grammar Focus3c）課件 （新版）人教新目標(biāo)版

第三課時第三課時Section A(Grammar Focus3c)單元同步語法精講 比較級和同級相比形容詞、副詞的原級即形容詞、副詞的原形形式，常用于very，so，quite，too之后，適用于句型asas(和一樣)。eg：The coat is very expensive.這件外套很貴。The boy is as old as the girl.那個男孩和那個女孩一樣大。He runs as fast as I他和我跑得一樣快。比較級常用于兩者之間進(jìn)行比較，表示其中一個比另一個“更”或“較”，后用連詞than連接另一個所比較的人或物。在上下文明確的情況下，比較級也可單獨使用。比較級的構(gòu)成(1)規(guī)則變化單音節(jié)和部分雙音節(jié)的形容詞、副詞一般在詞尾加er。eg：wildwildertalltaller以不發(fā)音的字母e結(jié)尾的只加r。eg：latelaterfinefiner以重讀閉音節(jié)結(jié)尾，末尾只有一個輔音字母，需雙寫詞尾輔音字母，再加er。eg：hothotterbigbigger多音節(jié)和部分雙音節(jié)詞，在原級前加more。beautifulmore beautifulcarefulmore careful(2)不規(guī)則變化good/wellbetterbad/illworsemany/muchmorelittlelessfarfarther/further比較級的用法(1)形容詞比較級常用于兩者之間的比較，表示兩者之間的差異，構(gòu)成形式多為“主語謂語(連系動詞)比較級than比較對象”。eg：They have more orange than we (do)/us.他們的橘汁比我們的多。在上下文意思明確的情況下，也可以單獨使用比較級。This coat is too small.Do you have a bigger one?比較級之前加much，far，a bit，a little，even，still，a lot 等詞修飾，用于加強(qiáng)語氣。eg：She is a little fatter than me.她比我胖一點。(2)asas意為“與一樣”，否定形式“not as/soas”意為“不如；不與一樣”也是一種表達(dá)比較的形式。但as與as之間用形容詞、副詞的原級。eg：This room is not as/so big as that one.這個房間不如那個房間大。This room is smaller than that one.單元同步語法強(qiáng)化訓(xùn)練一、單項選擇。1Do you enjoy Han Leis songs？(2014，南京)Yes.He is the winner of Im a singer .I cant think of anyone with a_voice.AbetterBbestCmoreDmost2I am sorry this coat is not big enough.I want a_one.(2014，威海)Abigger Bbig Csmaller Dsmall3I think English is as_as math.I agree with you.(2014，南充)Amore interesting Bmost interestingCthe most interesting DinterestingA A D 4Which season do you like_，winter or summer？(2014，北京)Summer.Awell BbetterCbest Dthe best5We are happy to see the city is developing _these years than before.(2014，臨沂)Aquickly Bthe most quicklyCvery quickly Dmore quicklyB D 二、用所給詞的適當(dāng)形式填空。6Liu Lu is _(good) at English than I.7Who has _(many) books，Zhang Li or Liu Ying?8It was cold yesterday，but it is much _(cold) today.9The doctor isnt as_ (smarter) as Mr.Wu.10Is your brother as _ as you?No，I am much _.
