一般現(xiàn)在時(shí)的句子
一般現(xiàn)在時(shí)的結(jié)構(gòu)我們可以從兩方面入手,一是從be 動(dòng)詞入手,肯定句:主語(yǔ)+be +其它,She is a student. I am a teacher.否定句:主語(yǔ)+be +not +其它,She isn’t a student. I am not a teacher.
一般疑問(wèn)句:be+主語(yǔ)+其它,Is she a student ? Are you a teacher?, 回答時(shí),肯定回答用Yes,主語(yǔ)+be,否定回答用No,主語(yǔ)+be的否定的縮寫。
be動(dòng)詞在一般現(xiàn)在時(shí)中學(xué)生很容易掌握,考試時(shí)它都是以各種時(shí)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(shí)態(tài)的形式出現(xiàn)在考題中。
二是從行為動(dòng)詞入手,而在從行為動(dòng)詞入手時(shí),我們還要從兩個(gè)方面來(lái)講解一般現(xiàn)在時(shí)的結(jié)構(gòu)。
