【问】 according to与according as有无区别?

【答】 应当弄清楚，according to中的to是介词，而according as中的as是连词，因此前者是复合介词，与名词、代词、动名词连用，而后者是复合连词，引导从句。请对比下列实例：

1. According to this book a tiger is really a big cat. (Thorndike)

按照这本书的说法，老虎实际上就是一种大猫。

2. The thermometer rises or falls according as the air is hot or cold.

寒暑表随空气的热冷而升降。

3. You will be praised or blamed according as your work is good or bad. (ALD)

你将依照你工作的好坏而受到奖惩。
