含有情态动词的被动语态
语态：在英语语言中，语态主要讨论句子主语与行为动词的关系。
语态有两种：主动语态和被动语态。
①
主语是动作的发出者(执行者)为主动语态。
　
e.g.
The
tall
boy
often
hits
his
classmates.
（主语boy是谓语动词hit的发出者）
②
主语是动作的接受者（承受者）为被动语态。
汉语中常用“被”、“给”、“由”、“受”等词用来表示被动;
而英语用：助动词be
+
及物动词的过去分词构成
e.g.
Chinese
is
spoken
by
the
most
people
in
the
world.
（主语Chinese是谓语动词speak的接受者）
