动词的–ing形式包括两种:
①现在分词:具有形容词和副词特征，可作定语、状语、表语、宾补等。
②动名词：具有名词特征，可作主语、宾语、表语等。现在分词的基本特点:

TheteacherteachingusChineseisMsWang.
=TheteacherwhoisteachingusChineseisMsWang.Thepeoplesittingbehindusaresoccerplayers.单个的verb-ing形式作定语，放在所修饰的名词前面；Verb-ing短语作定语则放在所修饰的名词之后。而且，作定语时，与现在分词的区别，动名词作定语表示名词的作用或功能，现在分词作定语表名词正在进行的动作。Translatethefollowingphrases.2.Verb-ingform—usedasanobjectcomplementIheardthegirlsingingintheclassroom.小结3能跟-ing形式作宾语补足语的常见动词有：3.Verb-ingform—

②.Whatpleaseshimmostisbathinginthesea．现在分词与过去分词作表语的区别:
