Well done! Good done?!

以下哪句不正確：

1. He runs quickly.

2. He runs fastly.

3. He runs fast.

答案是 2!

大部分的副詞(Adverbs of Manner)都是後綴-ly 的，如：

quick -> quickly

slow -> slowly

但也有特別例子 (即不加 -ly 的)：

fast -> fast

hard -> hard

early -> early

late -> late

good -> well

所以，我們說 "Well done" , 而非 "Good done" 哩！
