注意：
1)要避免重複使用比較級。

(對)He is clever than his brother.
2)要避免將主語含在比較對象中。

3)要注意對應句型，遵循前後一致的原則。
The population7 of Shanghai is larger than that of Beijing.
It is easier to make a plan8 than to carry it out.
4)要注意冠詞的使用，後有名詞的時候，前面纔有可能有名詞。
比較：
Which is large，Canada or Australia?
Which is the larger country，Canada or Australia?
She is taller than her two sisters.
She is the taller of the two sisters
可修飾比較級的詞
1)a bit，a little，rather，much，far，by far，many，a lot，lots，a great deal，any，still，even等
2)還可以用表示倍數的詞或度量名詞作修飾語。
3)以上詞(除by far)外，必須置於比較級形容詞或副詞的前面。
many，old 和far
1)如果後接名詞時，much more +不可數名詞
many more +可數名詞複數
2)old 有兩種比較級和最高級形式：older/oldest 和elder/eldest1. elder，eldest 只用於兄弟姐妹的長幼關係。
My elder brother is an engineer.
Mary is the eldest of the three sisters.

the + 最高級 + 比較範圍

形容詞最高級前通常必須用定冠詞 the，副詞最高級前可不用。

=It is a very important problem.
注意：使用最高級要注意將主語包括在比較範圍內。

=Nothing is easier than this.
=This is the easiest thing.
