1、精選優質文檔-傾情為你奉上在英語中通常用下列方式表示的詞:在形容詞或副詞前加more(如 more natural, more clearly )或加后綴 er (newer, sooner )。典型的是指形容詞或副詞所表示的質、量或關系的增加。英語句子中，將比較兩個主體的方法叫做“比較句型”。其中，像“A比B更”的表達方式稱為比較級;而“A最”的表達方式則稱為最高級。組成句子的方式是將形容詞或副詞變化成比較級或最高級的形態。英語比較級和最高級的用法一、形容詞、副詞的比較級和最高級的構成規則1.一般單音節詞和少數以-er，-ow 結尾的雙音節詞，比較級在后面加-er，最高級在后面加-est;(

2、1)單音節詞如：small smaller smallest short shorter shortesttall taller tallest great greater greatest(2)雙音節詞如：clever cleverer cleverest narrow narrower narrowest2.以不發音e結尾的單音節詞，比較在原級后加-r，最高級在原級后加-st;如：large larger largest nice nicer nicest able abler ablest3.在重讀閉音節(即：輔音+元音+輔音)中，先雙寫末尾的輔音字母，比較級加-er，最高級加-est;

3、如：big bigger biggest hot hotter hottest fat fatter fattest4.以“輔音字母+y”結尾的雙音節詞， 把y改為i，比較級加-er，最高級加-est;如：easy easier easiest heavy heavier heaviestbusy busier busiest happy happier happiest5.其他雙音節詞和多音節詞，比較級在前面加more，最高級在前面加most;如：beautiful more beautiful most beautifuldifferent more different most diff

4、erenteasily more easily most easily注意：(1)形容詞最高級前通常必須用定冠詞 the，副詞最高級前可不用。例句： The Sahara is the biggest desert in the world.(2) 形容詞most前面沒有the，不表示最高級的含義，只表示"非常"。It is a most important problem.=It is a very important problem.6.有少數形容詞、副詞的比較級和最高級是不規則的，必須熟記。如：good better best well better bestbad

5、worse worst ill worse worstold older/elder oldest/eldestmany/much more most little less leastfar further/farther furthest/farthest二、形容詞、副詞的比較級和最高級的用法1.“A + be +形容詞比較級 + than + B” 意思為“A比B更”。如：This tree is taller than that one. 這棵樹比那棵樹高。注意： 在含有連詞than的比較級中，前后的比較對象必須是同一范疇，即同類事物之間的比較。在比較級前面使用much，表示程度程度“

6、強得多”。如：A watermelon is much bigger than an apple. very, quite一般只能修飾原級，不能修飾比較級。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 getting cooler and cooler.天氣越來越涼爽。The wind became more and more heavily.風變得越來越大。Our school is becoming mo

7、re and more beautiful.我們的學校變得越來越美麗。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，花得越多。The sooner，the better.越快越好。5. 表示倍數的比較級用法：. A is times the size /height/length/width of B.如：The new

8、building is three times the height of the old one.這座新樓比那座舊樓高三倍。(新樓是舊樓的四倍高). A is times as big /high/long/wide/large as B.如：Asia is four times as large as Europe.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.我們學校比你們學校大兩倍。6.形容詞、副詞的最高級形式主要用來

9、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。7."否定詞語+比較級"，"否定詞語+ so as"結構表示最高級含義。Nothing is so easy as this.=Nothing is easier than this.=This is the easiest thing.8. 比較級與最高級的轉換：Mike is the most intelligent in

11、e brothers.(對) Tom is the tallest of the three brothers.2)下列詞可修飾最高級：by far, far, much, mostly, almost。This hat is nearly / almost the biggest.注意：a. very可修飾最高級，但位置與much不同。This is the very best.This is much the best.b. 序數詞通常只修飾最高級。Africa is the second largest continent.9.要避免重復使用比較級。(錯) He is more clev
