Grammar
1) The Sahara is the biggest desert in the world.
形容詞最高級(jí)前通常必須用定冠詞 the，副詞最高級(jí)前可不用。
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"。
It is a most important problem.
=It is a very important problem.
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
This hat is nearly / almost the biggest.
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)。
Africa is the second largest continent.
3) 句型轉(zhuǎn)換：

1. -Which is ____ season in Beijing? (2003年)
-I think it's autumn.
A. good B. better C. best D. the best
該題的核心詞為season。根據(jù)比較級(jí)與最高級(jí)的知識(shí), 兩者之間用比較級(jí), 而三者或三者以上用最高級(jí), 北京有四季, 因此本題應(yīng)選擇最高級(jí)。又因?yàn)樾稳菰~最高級(jí)前要加定冠詞the, 因此答案為D。
2. - Which is__________ , the sun, the moon or the earth?(2004年)
-- Of course, the moon is.
A. small B. smaller C. smallest D. the smallest
解析：正確答案為D。該題的核心詞在第一句句尾，"the sun, the moon or the earth", 提問(wèn)的對(duì)象為三者，應(yīng)該選擇最高級(jí)。
3. The air in Beijing is getting much _____ now than a few years ago.(2005年)
A. clean B. cleaner C. cleanest D. the cleanest
該題的核心詞為than，than一詞是比較級(jí)的標(biāo)志。
