答案]
一、概念
现在进行时表示说话时正在进行或发生的动作,也可表示
当前一段时间内的活动或现阶段正在进行的动作．
结构：助动词be ( am / is / are ) +现在分词.
二、现在分词的构成：
1.大多数动词后可在动词后直接加-ing．
Eg: carry-carrying,catch-catching,drink-drinking。

enjoy-enjoying hurry-hurrying。

do-doing。

read-reading。

think-thinking
2.如果动词以-e结尾,则去掉-e,再加-ing。

ing。

have-having。

make-making,ride-riding,write-writing,take-taking,use-using．3.如果动词只有一个元音字母,而
其后跟有一个辅音字母时,将此辅音字母双写,再加-ing 如：hit-hitting,let-letting。

put-putting,run-running,sit-sitting．
4.如果动词有两个音节,且重音在第二个音节上,则末尾的
辅音字母须双写,再加-ing。

如: for’etting,pre’fer-preferring,up’set-upsetting．试比
较’XXX。

’differ/differing,’profit/profiting,这些词的重音在第一个音节上,因此其末尾的辅音字母不双写．
5.以-ic末端的动词,应先把-ic变成-ick,再加-ing,eg: panic/panicking,ic/icking,但XXX。

die/dying,tie/tying是非凡变革要记着．
