小学现在进行时练习.doc

小学现在进行时一、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： 1. 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。 2. 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。 二、现在进行时的变化 肯定句式：主语 + be( am, is, are)+ V-ing +其它. e.g 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. e.gI 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？ e.gAre 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？ e.gWhat are you doing in the house?Where is he going?When is she doing her homework?三、动词的ing形式变形1）一般情况在动词原形后直接加 -ing go-going ， stand-standing ， cook-cooking, do-doing2）以e 结尾的动词，要去掉 e + ing. take-taking,make-making,have-having3) 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ingget- getting ，put-putting,runrunning, begin-beginningswim-swimminge.g eat-eating这个动词有ea组合音，所以不能双写study-studying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.die-dying ，lielying， tie-tying一、写出下列动词的现在分词： play_ run_ swim _make_ go_ like_ write_ ski_ read_ have_ sing _ dance_ put_ see_ buy _ love_ live_ take_ come _ get_ stop_ sit _ begin_ shop_二用所给的动词的正确形式填空：1.
