［析］ so…that与so that的用法有相同之处，那就是其后接从句，而so as to 其后要接不定式，即动词原形。这样的词组还有：in order to。

［误］ I want to buy same stamp that you have.

［正］ I want to buy the same stamp as you have.

［析］ the same…as (that)这是个固定用法，在same前的定冠词是不能少的。而the same…that意为"我要的就是那一个"。而the same…as为"要的是和……一样的东西"。

［误］ Before I do not give you the answer, I'll ask you some questions.

［正］ Before I give you the answer, I'll ask you some questions. ［析］ 这种错误是由于受中文的影响。在中文中可以讲"我没给你答案前"。而英文用了before就不要再用否定句了。
