swimming是swim的进行时吗?为什么是ming/ 为什么swim的现在进行时是swimming.play的现在进行时是playing? 为什么swim的现在进行时是swimming.play的现在进行时是playing? 为什么有的现在进行时的单词是这样：write---writing 而不是：swim---swimming呢?( 就是swim结尾有双写m,有的单词没双写,就是上面的write.) 为什么都是以元音字母和辅音字母结尾的动词的进行式不一样如eat和swim,eat的进行式是eating 字母t不重复 swim的进行式是swimming m重复有规律吗 swim 为什么这在进行时 变成swimming? swim和swimming的用法. I want to go swimming.为什么是swimming而不是swim?有同义句吗.

We often go (swim) there是swim 还是swimming? 请问learn to swim等于learn swimming吗?1楼的请问是我的问题太幼稚了吗？ shop和swim的用法我经常在书上看到shopping和swimming,为什么不是现在进行时还要用现代分词 don't后面的单词是动名词吗就是Don't _______后面有两个选择：A.swimming B.swim 请问swim和swimming的区别, she 横线（swim）in the swimming poolshe 横线(swim)in the swimming poolshe likes 横线 (swim)in the swimming pool上面打错了这个是对的
