两个分句中都要求使用同一动词时,我们通常用助动词来表示第二个动词。
A as+原级+as用于肯定句,as/so+原级+as用于否定句:
He worked as slowly as he dared.
他干活敢多么磨蹭就多么磨蹭。
He doesn’t snore as/so loudly as you do.
他打鼾的声音没有你响。
It didn’t take as/so long as I expected.
花的时间比我预料的短。
than与比较级连用:
He eats more quickly than I do/than me.
他比我吃得快。
He played better than he had ever played.
他比过去任何时候都演奏得好。
They arrived earlier than I expected.
他们比我预料的到得早。
the+比较级…the+比较级结构中也用副词:
The earlier you start the sooner you’ll be back.
你出发得越早,回来得就越早。
最高级可与of+名词连用:
He went(the)furthest of the explorers.
在所有探险者中他走得最远。
但这种结构不常用。这类句子应当用比较级来表达,如上文所述。副词的最高级(不加the)+of all这种结构很常用,但all常指同一主语的其他动作:
He likes swimming best of all.
他最喜欢游泳。(他喜欢游泳胜过其他一切运动。)
这时of all可以省略。
