4、be 動詞的一般現(xiàn)在時的基本句型,二. 實義動詞的一般現(xiàn)在時,1、什么叫實義動詞？ 實義動詞是指表示有具體意思的動詞,也叫行為動詞。 如: like(喜歡）, eat（吃）, live（居住）, have（有）, run（跑） 等等。 實義動詞占英語中動詞的絕大多數(shù)。,我們已學過的be 動詞可譯成“是”，有時譯成“成為”，有時則沒有具體意思如： “She is tall.”這句譯成： “她很高”。故be 動詞不屬于實義動詞。,2、一般現(xiàn)在時實義動詞作謂語的時侯有兩種形式：,動詞原形；如: enjoy 第三人稱單數(shù)動詞形式；如: enjoys,主語 + (+其它)。,行為動詞原形,行為動詞的單數(shù)
