3、 this English song.许多学生喜爱这首英文歌曲。(主动语态，句子的主语lots of students是动作love的执行者)This English song is loved by lots of students.(被动语态，句子的主语this English song是动作love的承受者)（2）一般现在时的被动语态的构成被动语态由“助动词be及物动词的过去分词”构成，其中的助动词be有人称、数和时态的变化。一般现在时的被动语态的各种句式如下：句式构成例句肯定句主语am/is/are及物动词的过去分词(其他)English is widely used all over
