形容詞和副詞 比較級 最高級 教案

1、形容詞、副詞的比較級和最高級的用法：當(dāng)兩種物體之間相互比較時，我們要用形容詞或副詞的比較級；當(dāng)相互比較的物體是三個或三個以上時，我們就要用形容詞或副詞的最高級。 形容詞、副詞的比較級和最高級的變化規(guī)律：1. 單音節(jié)形容詞或副詞后面直接加-er或-esttalltallertallest fastfasterfastest2. 以-e結(jié)尾的單音節(jié)形容詞或副詞直接加-r或-stlargelargerlargest nicenicernicest3. 以-y結(jié)尾的形容詞或副詞，改-y為-i再加-er或-estbusybusierbusiest earlyearlierearliest4. 形容詞或副

2、詞是重讀閉音節(jié)時，雙寫最后的輔音字母，再加-er或-esthothotterhottest bigbiggerbiggest5. 多音節(jié)形容詞或副詞前面直接加more或mostdeliciousmore deliciousmost deliciousbeautifulmore beautifulmost beautiful6. 不規(guī)則變化good (well)betterbest bad (badly)worseworst常用的不規(guī)則變化的形容詞的比較級和最高級: bad worse worstfar farther (further) farthest（只指距離）(furthest)（用處較

3、廣）good better bestlittle less leastmanymuch more mostold elder ( older ) eldest（僅指人）(oldest)（指人和物）形容詞前如加 less 和 least 則表示"較不"和"最不" important 重要 less important 較不重要 least important 最不重要 fartherfarthest和furtherfurthest這些形式都可以指距離。further同樣可以指“另外的更多的”，主要和抽象名詞一起用：Further education wil

4、l be meaningful很快會得到更多的供應(yīng)。Further discussion would be pointless繼續(xù)討論辯論是無意義的。I am too tired to go farther.elder，eldest；older，oldestelder和eldest主要表示的是長幼順序而非年齡大小。主要用于表示家庭成員之間的長幼關(guān)系，如my elder brother（我的兄長哥哥），her eldest boygirl（她的長子長女）。但在than前不能用elder，只能用older：He is older than I am他比我年齡大。A、形容詞的原級可與asas連用表示

5、“和同樣”，與not assoas連用表不“不如那樣”：A boy of sixteen is often as tall as his father一個16歲的男孩常長得和他父親一樣高。He was as white as a sheet他面色蒼白如紙。Your coffee is not asso good as my mothers你煮的咖啡不如我母親煮的好。 幾個關(guān)于as.as的常見句型： (1)as.as possible 盡 可能 Please answer my question as soon as possible.請盡快回答我的問題。 (2)as.as usual/befo

6、re 像往常一樣 像以前一樣 She looks as pretty as before.她看起來和以前一樣漂亮。 (3)長達(dá)as long as. (引導(dǎo)條件狀語從句) 只要 It took us as long as three years to carry out the plan.我們花了長達(dá)三年的時間才完成這項計劃。 (4)as far as 遠(yuǎn)至 He walked as far as the railway station yesterday evening.昨天傍晚，他一直散步到火車站。 (5)as well as She cooks as well as her mother

7、 does.她燒菜燒得跟她母親一樣好。 一些帶有as.as結(jié)構(gòu)的常見短語歸納： as busy as a bee像蜜蜂一樣忙碌 as easy as ABC像ABC一樣容易 as deep as a well像井一樣深 as light as a feather像羽毛一樣輕 as soft as butter像黃油一樣軟 as rich as a Jew像猶太人一樣富裕形容詞比較級的用法: 形容詞的比較級用于兩個人或事物的比較,其結(jié)構(gòu)形式如下: 主語+謂語(系動詞)+ 形容詞比較級+than+ 對比成分。 也就是, 含有形容詞比較級的主句+than+從句。注意從句常常省去意義上和主句相同的部分

8、, 而只剩下對比的成分。 Our teacher is than we are. 我們老師的個子比我們的高。 It is today than it was yesterday. 今天的天氣比昨天暖和。 This picture is than that one. 這張照片比那張照片漂亮。This meeting is than that one. 這次會議不如那次會議重要。 The sun is than the moon. 太陽比月亮大得多。形容詞最高級的用法: 形容詞最高級用于兩個以上的人和物進(jìn)行比較, 其結(jié)構(gòu)形式為: 主語+謂語(系動詞)+the+形容詞最高級+名詞+表示范圍的短語或從

9、句。 She is student her class. 她是班上最好的學(xué)生。 Shanghai is one of cities China. 上海是中國最大城市之一This is apple I have ever met. 這是我見到的最大的蘋果。 Tom is boy in his basketball team. 湯姆是他們籃球隊中個子最高的孩子。 2“比較級 + and + 比較級”或“more and more +原級”表示“越來越”如：It becomes warmer and warmer when spring comes. 春天來了，天氣變得越來越暖和了。It is ge

10、tting cooler and cooler.天氣越來越?jīng)鏊he wind became more and more heavily.風(fēng)變得越來越大。Our school is becoming more and more beautiful. 我們的學(xué)校變得越來越美麗。3在含有or的選擇疑問句中，如果有兩者供選擇，前面的形容詞要用比較級形式。如：Who is taller,Tim or Tom? 誰更高，Tim還是Tom?4. “the +比較級, the+比較級”，表示“越越”。The more money you make, the more you spend.錢你賺得越多，花得

11、越多。The harder you work,the more you get.The sooner，the better. 越快越好。5.如果在兩者之間表示“最”時要在比較級前加the，而且還用of the two, of the pair短語： John is the cleverer of the two boys. Of the two boys, John is the cleverer6. 表示倍數(shù)的比較級用法： A is times as big /high/long/wide/large as B.如：Asia is four times as large as Europe.

12、亞洲是歐洲的四倍大。(亞洲比歐洲大三倍). A is times larger /higher/longer/wider than B.如：Our school is twice bigger than yours.我們學(xué)校比你們學(xué)校大兩倍。7.形容詞、副詞的最高級形式主要用來表示三者或三者以上人或事物的比較，表示“最”的意思。句子中有表示范圍的詞或短語。如：of the three, in our class等等。如：He is the tallest in our class. 他在我們班里是最高的。8. 比較級與最高級的轉(zhuǎn)換： Mike is the most intelligent i

13、n his class.

14、He is more cleverer than his brother. (對) He is more clever than his brother. (對) He is cleverer than his brother. 9.要避免將主語含在比較對象中。 (錯) China is larger than any country in Asia.
