一般現(xiàn)在時的句子
一般現(xiàn)在時的結(jié)構(gòu)我們可以從兩方面入手,一是從be 動詞入手,肯定句:主語+be +其它,She is a student. I am a teacher.否定句:主語+be +not +其它,She isn’t a student. I am not a teacher.
一般疑問句:be+主語+其它,Is she a student ? Are you a teacher?, 回答時,肯定回答用Yes,主語+be,否定回答用No,主語+be的否定的縮寫。
be動詞在一般現(xiàn)在時中學(xué)生很容易掌握,考試時它都是以各種時態(tài)出現(xiàn)在卷子中,結(jié)構(gòu)都不是很難,大多數(shù)以數(shù)的形式或時態(tài)的形式出現(xiàn)在考題中。
