副詞的概念：
副詞是指在句子中表示行為或狀態(tài)特征的詞，用來修飾動詞、形容詞、其他副詞、介詞短語、非謂語動詞乃至整個句子，表示時間、地點、程度、方式等概念。
副詞的位置：
1）在動詞之前。
2）在be動詞、助動詞之后。
3）多個助動詞時，副詞一般放在第一個助動詞后。
注意：
a. 大多數(shù)方式副詞位于句尾，但賓語過長，副詞可以提前，以使句子平衡。
如：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。
如：He speaks English well.
副詞的排列順序：
1）時間，地點副詞，小單位的在前，大單位在后。
2）方式副詞，短的在前，長的在后，并用and或but等連詞連接。
如：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.
�。▽Γ㊣ like English very much.
