3.修饰语

比较级可不带修饰语，若表示程度或差别大小时，用much, a little, even, far, a lot, a bit, no, still 或数词修饰。但若用“of the two”时，比较级前面必须带“the”.

It was far more interesting than I expected.

She is the nicer one of the two.

1.表示“比...更”，用比较级形容词+than+比较成分，表示前者“超过”后者。than后主语

的述语动词往往省略，非正式用法的than后的人称代名词可用宾格。

我游泳比你好。

But you are taller and stronger than I (am).

但是你比我高，比我壮。

2. 否定的比较级表示“较...低；不及...”，用less+原级形容词+than+比较成分，表示前者不及后者。

我一直设法帮助比我不幸的人。

At least you are less generous than I.

至少你没有我慷慨。
