第九讲-现在进行时.docVIP

PAGE4 / NUMPAGES4第九讲 现在进行时 现在进行时的构成：由be动词+ v-ing构成。(V-ing表示在动词后面加上ing) 现在进行时常用以下几种情况： 当句子中有now时，常表示动作正在进行，这时要用现在进行时。 如：They are playing basketball now.现在他们正在打篮球。 以look, listen开头的句子，提示我们动作正在进行，这时要用现在进行时。如： Listen！She is singing an English song.听，她正在唱英语歌。 现在进行时的变化 肯定句式：主语 + be( am, is, are)+ V-ing +其它. I am doing my homework. He is washing his clothes. You are flying a kite. 否定句式：主语 + be(am, is, are) +not + V-ing +其它. I am not doing my homework. He is not washing his clothes. You are not flying a kite. 一般疑问句：Be(am, is, are) + 主语 + V-ing +其它？ Are you doing your homework? Is he washing his clothes? Am I flying a kite? 特殊疑问句：疑问词+ be(am, is, are)+ 主语 + V-ing +其它？ What are you doing in the house? Where is he going? When is she doing her homework? 动词的ing形式的变化 一般情况在动词原形后直接加 -ing gogoing ， standstanding ， cookcooking, dodoing 以e 结尾的动词，要去掉 e + ing. taketaking, makemaking, havehaving 3) 重读闭音节动词，要双写最后一个字母， 再加ing(所谓“重读闭音节”：从动词的末尾开始寻找，如果倒数第二个字母是元音字母，并且元音字母两边的字母没有组合音，没有变音，都独自发音，这样的动词都必须，双写后，再加上ing get- getting ， putputting, run—running, beginbeginning swimswimming eateating 这个动词有ea组合音，所以不能双写studystudying 这个动词倒数第二个字母不是元音字母，不能双写 4) 以 -ie 结尾的动词，把 ie 变成 y ，再加 ing. lie—lying， tietying 写出下列动词的现在分词： play________ run__________ swim _________make__________ go_________ like________ write________ read________ have_________ sing ________ put_________ see________ buy _________ love______ take_________ come ________ get_________ stop_______ sit ________ shop________ draw _______ cook ________ talk _________ wash _________ go _________ fly ________二、用所给的动词的正确形式填空：The boy __________________ ( draw)a picture now.Listen .Some girls _______________ ( sing)in the classroom .My mother _________________ ( cook )some nice food??now.What _____ you ______ ( do ) now?Look .
