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(lái)修飾動(dòng)詞、形容詞、其他副詞、介詞短語(yǔ)、非謂語(yǔ)動(dòng)詞乃至整個(gè)句子，表示時(shí)間、地點(diǎn)、程度、方式等概念。
副詞的位置：
1）在動(dòng)詞之前。
2）在be動(dòng)詞、助動(dòng)詞之后。
3）多個(gè)助動(dòng)詞時(shí)，副詞一般放在第一個(gè)助動(dòng)詞后。
注意：
a. 大多數(shù)方式副詞位于句尾，但賓語(yǔ)過(guò)長(zhǎng)，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(shí)間，地點(diǎn)副詞，小單位的在前，大單位在后。
2）方式副詞，短的在前，長(zhǎng)的在后，并用and或but等連詞連接。
如：Please write slowly and carefully.
3）多個(gè)不同副詞排列：程度+地點(diǎn)+方式+時(shí)間副詞。
注意：副詞very可以修飾形容詞，但不能修飾動(dòng)詞。
