【拓展】现在分词的构成规则：
1)一般情况下在动词词尾加ing。例如：
look
→_______
sleep
→
_______
say
→
_______
2)以不发音的e结尾的动词，去掉
e加ing。例如：
take
→
_______
dance
→
_______
write
→
_______
looking
sleeping
saying
taking
dancing
writing
3)以一个辅音字母结尾的重读闭音节，双写最后一个字母，再加-ing。例如：swim
→
__________
【巧记】现在分词的构成规则:
look,
listen是标志，现在进行正发生。
有时now在句中现，be
+v-ing时态成。
若问be用何形式，须看主语数、人称。
