11)倍數(shù)+ as + adj. + as <=> 倍數(shù)+ the … + of。例如:

5. 形容詞最高級(jí)用法
the + 最高級(jí) + 比較范圍
1)形容詞最高級(jí)前通常必須用定冠詞 the,例如:
The Sahara is the biggest desert in the world. 撒哈拉沙漠是世界上最大的沙漠。
形容詞most前面沒(méi)有the,不表示最高級(jí)的含義,只表示"非常"。例如:
It is a most important problem. =It is a very important problem. 這是個(gè)很重要的問(wèn)題。
注意:使用最高級(jí)要注意將主語(yǔ)包括在比較范圍內(nèi)。
(錯(cuò)) Tom is the tallest of his three brothers.
(對(duì)) Tom is the tallest of the three brothers.
2) 下列詞可修飾最高級(jí),by far, far, much, mostly, almost。例如:
This hat is nearly / almost the biggest. 這帽子差不多是最大的了。
注意:
a. very可修飾最高級(jí),但位置與much不同。
This is the very best.
This is much the best.
b. 序數(shù)詞通常只修飾最高級(jí)。例如:
Africa is the second largest continent.非洲是第二大洲。
