副詞主要用來修飾動詞，形容詞，副詞或其他結構。
一、副詞的位置：
1) 在動詞之前。
2) 在be動詞、助動詞之後。
3) 多個助動詞時，副詞一般放在第一個助動詞後。
注意：
a. 大多數方式副詞位於句尾，但賓語過長，副詞可以提前，以使句子平衡。
We could see very clearly a strange light ahead of us.
b. 方式副詞well，badly糟、壞，hard等只放在句尾。
He speaks English well.
二、副詞的排列順序：
1) 時間，地點副詞，小單位的在前，大單位在後。
2) 方式副詞，短的在前，長的在後，並用and或but等連詞連線。
Please write slowly and carefully.
3) 多個不同副詞排列：程度+地點+方式+時間副詞。
注意：副詞very 可以修飾形容詞，但不能修飾動詞。
改錯：(錯) I very like English.

注意：副詞enough要放在形容詞的後面，形容詞enough放在名詞前後都可。
