1、比较级和最高级,英语句子中，将比较两个主体的方法叫做“比较句型”。其中，像“A比B更”的表达方式称为比较级。,最高级表示三者或三者以上的人或物进行比较时，用最高级。,1“A+be+形容词比较级+than+B”意思为“A比B更”。,如：This tree is taller than that one.这棵树比那棵树高。,在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。,在比较级前面使用much，表示程度“强得多”。,如：A watermelon is much bigger than an apple.,very,quite一般只能修饰原级，不能修饰比较级。,

2、注意：,2“比较级+and+比较级”或“more and more+原级”表示“越来越”,如：It becomes warmer and warmer when spring comes.,春天来了，天气变得越来越暖和了。,It is getting cooler and cooler.,天气越来越凉爽。,The wind became more and more heavily.,风变得越来越大。,Our school is becoming more and more beautiful.,我们的学校变得越来越美丽,3在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。

3、,如：Who is taller,Tim or Tom?谁更高，Tim还是Tom?,4.“the+比较级,the+比较级”，表示“越越”。,The more money you make,the more you spend.,钱你赚得越多，花得越多。,The sooner，the better.,越快越好。,5.表示倍数的比较级用法：,.A+be+倍数+times+the+形容词对应名词形式+of+B.,如：The new building is three times the height of the old one.,这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高),.A+be+倍数+

4、times+as+原级+as+B.,如：Asia is four times as large as Europe.,亚洲是欧洲的四倍大。(亚洲比欧洲大三倍),.A+be+序数词+比较级+than+B.,如：Our school is twice bigger than yours.,我们学校比你们学校大两倍。,6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最”的意思。,句子中有表示范围的词或短语。如：of the three,in our class等等。,如：He is the tallest in our class.,他在我们班里是最高的。,7.“否定词语

5、+比较级”，否定词语+so as结构表示最高级含义。,Nothing is so easy as this.,=Nothing is easier than this.,=This is the easiest thing.,形容词的比较等级构成方式:1.一般单音节adj 的比较级多在原形上加-er,最高级加-est.多音节adj在原形前加more,最高级加most,2.辅音字母加y结尾时去y变i再加er eg.friendly friendlier friendliest,3.以不发音的e结尾时加r/st.eg.fine finer finest4.重读闭音节结尾的词,如末尾是一个辅音字母,
