三. 动词的现在分词的构成：
（1）一般在动词末尾直接加ing, read→reading; work→working
（2）以不发音字母e结尾的动词，先去掉e,再加ing，
如 skate →skating make →making dance → dancing write → writing
have → having ride → riding come → coming type→typing
（3）少数几个以ie结尾的动词要变ie为y, 再加-ing
die→dying tie→tying lie→lying
★（4）辅+元+辅结构，应双写末尾的辅音字母，再加ing,
如： putting running beginning stopping swimming shopping
jogging sitting getting forgetting letting digging
planning preferring
