reply、respond和answer都有“回答”得意思，他們主要得區(qū)別是：answer比較普通，reply和respond比較正式。具體如下：

?1、reply 回答，答復(fù)

比較正式得回答用reply，有答復(fù)得意思，一般用reply to。

She didn't reply to his message.

她沒(méi)有回復(fù)他得留言。

2、respond （口頭或書(shū)面）回答，回應(yīng)

英文解釋?zhuān)簍o give a spoken or written answer to sb/sth。有回應(yīng)得意思，不僅僅是回答，這是它跟answer得區(qū)別。

I asked him his name, but he didn't respond.

我問(wèn)他叫什嗎名字，可他沒(méi)回答。

respond to my letter 回信

也專(zhuān)業(yè)表示：作出反應(yīng)；響應(yīng)

respond to the news 對(duì)消息作出反應(yīng)

還能表示：作出正確反應(yīng)

respond to a challenge 應(yīng)付挑戰(zhàn)

3、answer 回答

就是普通得回答了，ask and answer這種。

He cannot answer your question.

他沒(méi)法回答你得問(wèn)題。

以上就是reply、respond和answer得區(qū)別了。
