(4)以 y 结尾的动词直接加 -ing carry—— carrying enjoy—— enjoying (5)以ie结尾的动词，把ie改为y ，再加-ing die---dying lie---lying 现在分词用途多，进行时态不可缺。 它的构成很好记，动词后缀ing。 词尾若有哑音e，去e再加没问题。 辅重读闭音节，这个字母要双写。 还有一点要注意，改ie为y再加ing 现在分词大变身 现在进行时的句式 1.肯定句一主语+be+doing 如: I am doing my homework. 2.否定句一主语+be+not+doing 如: I am not doing my homework. 3.一般疑问句-be提到句首(注意人称变化) 如: Are you doing your homework? 4.特殊问句: (1)对谓语动词进行提问的 :What + be +主语 + doing+其他? 如：What is the old man doing under the tree?
