二、副词的比较级和最高级
1.副词和形容词一样,也有比较级和最高级形式。

但单音节词和少数双音节词可以加词尾的方法构成比较级和最高级(a),双音节词和多音节词大多以加more 和most的方法构成比较级和最高级(b):
1) 原级比较级最高级
a. hard harder hardest
fast faster fastest
late later latest
early earlier earliest
b. quickly more quickly most quickly
strongly more strongly most strongly
carefully more carefully most carefully
2) 副词的比较级和最高级也有不规则的形式:
原级比较级最高级
well better best
badly /bad/ill worse worst
little less least
much more most
far farther, further farthest, furthest
2.副词比较级的使用:
1)单独使用:
He’ll come back sooner or later. 他迟早会回来的。

Please speak more slowly. 请讲慢一点。

Let’s talk more another time. 改天我们再多聊聊。

Can’t you stay longer? 你不能再多呆一会吗?
He should speak less and listen more. 他应当少说多听。

2)和than一起使用:
She swims better than I. 他游泳游得比我好。

He arrived earlier than usual. 他到得比平时早。

He studied the subject further than I do. 这问题他研究得比我深入。

3)比较级前有时可有状语修饰:

He walked no further. 他没再往前走。

Helen came late, but her sister came still later. 海伦来晚了,而她妹妹来得更晚。

He works a lot harder than before. 她工作比过去努力多了。

Can you come over a bit more quickly? 你能稍稍快一点来吗?
3.副词最高级可修饰动词,前面多数不带定冠词the:
He laughs best who laughs last. (谚)谁笑在最后谁笑得最好。
