①.A is …times the size /height/length/width 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)②.A is …times as big /high/long/wide/large 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)③.A is …times larger /higher/longer/wider 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.如：He is the tallest in our class.他在我们班里是最高的.7.“否定词语+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.8.比较级与最高级的转换： Mike is the most intelligent in his class.Mike is more intelligent than any other student in his class 9.修饰比较级和最高级的词
