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.

(对) Tom is the tallest of the three brothers. 2)下列词可修饰最高级:by far, far, much, mostly, almost。 This hat is nearly / almost the biggest. 注意: a. very可修饰最高级，但位置与much不同。 This is the very best. This is much the best. b. 序数词通常只修饰最高级。 Africa is the second largest continent. 8.比较级、最高级使用中需注意的地方： 1）要避免重复使用比较级。 (错) He is more cleverer than his brother. (对) He is more clever than his brother. (对) He is cleverer than his brother. 2）要避免将主语含在比较对象中。 (错) China is larger that any country in Asia. (对) China is larger than any other country in Asia. 3）要注意对应句型，遵循前后一致的原则。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out. 4）要注意冠词的使用，后有名词的时候，前面才有可能有名词。 比较:Which is larger, Canada or Australia 与Which is the larger country, Canada or Australia She is taller than her two sisters. 与She is the taller of the two sisters. 【例题解析】 1.
