1、小学现在进行时 1、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。 2、现在进行时的变化 肯定句式：主语 + be( am, is, are)+ V-ing +其它
2、. 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
3、? 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? 3、动词的 ing 形式的变化 1）一般情况在动词原形后直接加 -ing go-going ， stand-standing ， cook-cooking, do-doing 2）以 e 结尾的动词，要去掉 e + ing. take-taking, make-making, have-having
4、 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 ， put-putting, runrunning, begin-beginning swim-swimmingeat-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.lielying， tie-ty
