托福语法技巧:than/as+代词+助动词

 当than或as¹的前后所用的动词相同时，常可以用助动词代替第二个动词：

I earn² less³ than he does．

我比他钱挣得少。

主句与从句中的动词不必使用同一时态：

He knows more than I did⁴ at his age．

他要比我在他这个年龄时懂得多。

如从句由than/as＋I/we/you+动词组成而时态并无变化时，常常将动词省略：

I'm not as old as you（are）．

我没有你年龄大。

He has more time than I/we（have）．

他的时间比我/我们多。

正规英语中as/than后仍使用I/we，因为动词虽被省略，代词仍被看做是动词的主语，因此仍用主格。但在非正式英语中，me/us更常用：

He had⁵ more time than me．

他比我时间多。

They are richer than us．

他们比我们富有。

如than/as后跟he/she/it+动词，常常保留动词：

You are stronger than he is．

你比他强壮。

但在极正式的英语中，可以用he/she/they而免去动词。在非常口语化的英语中可用him/her/them而免去动词。

这些规则也适用于副词比较级：

I swim better than he does/better than him．

我游泳比他好。

They work harder than we do/harder than us．

他们比我们干得卖劲。

You can't type⁶ as fast as I can/as fast as me．

你打字不如我快。
