形容詞級前通常必須用定冠詞 the，副詞級前可不用。
形容詞most前面沒有the，不表示級的含義，只表示“非常”。
It is a most important problem.
=It is a very important problem.
注意： 使用級要注意將主語包括在比較范圍內(nèi)。
（錯） Tom is the tallest of his three brothers.
（對） Tom is the tallest of the three brothers.
2） 下列詞可修飾級，by far， far， much， mostly， almost
This hat is nearly / almost the biggest.
注意：
a. very可修飾級，但位置與much不同。
This is the very best.
This is much the best.
b. 序數(shù)詞通常只修飾級。
Africa is the second largest continent.
3） 句型轉(zhuǎn)換：
Mike is the most intelligent in his class.
Mike is more intelligent than any other students in his class.
4） “否定詞語+比較級”，“否定詞語+ so… as”結(jié)構(gòu)表示級含義。
Nothing is so easy as this.
=Nothing is easier than this.
=This is the easiest thing.
和more有關(guān)的詞組
1） the more… the more… 越……就越……
The harder you work，the greater progress you‘ll make.
2） more B than A 與其說A不如說B
less A than B
He is more lazy than slow at his work.
= He is less slow than lazy at his work.
3） no more… than… 與……一樣……，不比……多
The officials could see no more than the Emperor.
no less… than… 與……一樣……
He is no less diligent than you.
4） more than 不只是，非常
She is more than kind to us all.
典型例題
1）The weather in China is different from____.
A. in America B. one in America C. America
D. that in America
答案：D. 本題意為“中國的天氣比美國熱。”比較的是天氣而不是國家，C不能選。A沒有名詞，后句成分不全，排除。B和D中，B中的one常用來代替可數(shù)名詞，而that可車以代替不可數(shù)或抽象名詞，所以選D。
2）After the new technique was introduced，the factory produced ___ tractors in 1988 as the year before.
A. as twice many B. as many twice C. twice as many D. twice many as
答案C. 此句意為“這個廠1988能生產(chǎn)的拖拉機(jī)是往年的兩倍”。 表示倍數(shù)用“倍數(shù)+ as + 形容詞原形+ as +比較對象”的句型。所以此句答案為C。
This ruler is three times as long as that one.
