托福语法技巧:than/as+代词+助动词

（单词翻译:单击）

 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。
