初中英语简易实用语法导学练3：主系表结构

初中英语简易实用语法导学练3：主系表结构 主系表结构(S+V+P)英语中有一类动词叫连系动词，它后面用来说明主语“是什么”、“怎么样”的成分，叫做表语。此结构中，动词必须是_________动词。表语多由__________________________充当。 be动词。主语人称代词名词Iyouhesheitwethey单数复数形式amareisisisareareisare过去式：am/is—was，are—were1)      The house ______ very large.2)      We _________ in the music room.思考：系动词很多时候是不翻译出来的（有时翻译成‘是’），那么我们一个句子中不使用系动词行不行？为什么？ ______________________________注意：be动词在构成进行时态、被动语态的时候，或在“be going to +动词原形”, “be to +动词原形”的结构中，是助动词，不是系动词，因此要区别主系表结构与be作助动词的情况！He was sleeping in class.  was 是系动词还是助动词？________________ 系动词的分类：某些动词在表示某些特定意义的时候，也可以作连系动词用，我们在把它们分为三类：     第一类表示持续状态或结果。比如: Keep, remain, continue, stay, lie, prove, turn out等。1)        The students ________________ quiet in class2)        He _______________ single all his life.3)        The weather turned out fine. _______________________   第二类　表示感觉的连系动词。这类动词有：look, sound, smell, taste, feel等。1)        It tastes good.2)        His idea _____________ reasonable.3)        The farm ___________ like a large beautiful garden.4)        I __________ tired after the long journey.   第三类　表示变化的连系动词。这类动词有：become, get, turn, go, come, fall等。1)        He became a teacher at last.2)        She became famous in 1990.3)        My dream will _________ true.思考：以上讲了三类系动词，be动词属于哪一类？______________ 定语的位置   单词作定语一般放在被修饰的名词前面。
I like _______________________  (那个有趣的故事).   短语或句子作定语放在被修饰名词后面。
He will buy the bag 〔on the table〕.
