become是英語中的一個(gè)常用單詞，意思是成為、變得，表示情況的開始、發(fā)展和結(jié)束的變化，become是系動(dòng)詞，也可用作及物動(dòng)詞，還可表示“適宜，合適”。

become的過去分詞

過去分詞是become；過去式became；現(xiàn)在分詞是becoming；第三人稱單數(shù)是becomes。

become用法：

become后接動(dòng)詞的過去分詞可表示被動(dòng)或結(jié)果，此時(shí)一般不接by短語。

become用作及物動(dòng)詞時(shí)，還可表示“適宜，合適”。

become of只能與疑問代詞what（ever）連用，用于直接或間接疑問句中，表示“變得怎樣”，后接人或有形的'東西，多用于完成時(shí)或?qū)頃r(shí)。

become是非持續(xù)性動(dòng)詞，不能與表示一段時(shí)間的狀語連用。但可用于完成時(shí)態(tài)。

become是系動(dòng)詞還是實(shí)義動(dòng)詞

become用作連系動(dòng)詞，意為“成為”，其后可接：

1.名詞

become后面接什么詞性

become后面接形容詞或者名詞，例如：become adult（名詞）；become strong（形容詞）。

用法：

1.用作連系動(dòng)詞，其后可接名詞、形容詞、過去分詞等作表語：

2.become是終止性動(dòng)詞，因此要表示“成為…有多長(zhǎng)時(shí)間”，英語不能將become與表示一段時(shí)間的詞或短語連用：
