3．根据以上例句可得出结论：现在进行时的被动语态必须满足两个条件：一是借助于________，二是要有________分词。

（2）现在进行时除表示“目前/现在正在发生或进行的动作”这一含义之外，还可以与频度副词连用，表示某种感情色彩。

（3）现在进行时与表示短暂性的动词go，come，leave，start，begin，see off等连用时，可表示将来的含义。

二、现在进行时的被动语态的构成

现在进行时的被动语态的构成：am/is/are＋being＋过去分词。它的否定形式是把not放在第一个助动词am/is/are之后，即：am/is/are＋not＋being＋过去分词。一般疑问句的形式是把第一个助动词放在句首，句末改为问号，即Am/Is/Are＋主语＋being＋过去分词？特殊疑问句的形式是把特殊疑问词放在一般疑问句的前面。
