不是说一个句子中必须有动词么.那这句话怎样理解 Swimming is a good exercise.
动词就不能直接做主语吗？那这句话怎么理解：
Break it up into smaller portions``````咋不说breaking it up`````

你好,你说得不错,一个句子中是必须有动词,但是你可能忘了,动词也分实义动词（如swim,hit）和助动词（am ,is,are 及其过去式等）,所以 Swimming is a good exercise. 中的 ”is “就是这句话的动词.
希望可以解答你的疑惑
再问：动名词一定要做主语吗？ swim一定要变成ing 形式吗
再答：你好 1动名词一定要做主语吗？不一定，你把动名词看成一个名词就可以了，名词可以做的成分，它都可以坐，如宾语：My favorite sport is swimming. 2swim一定要变成ing 形式吗你是说这句话里面吗？那当然了，这句话中swimming是主语，主语不可以是动词的，可以是名词，代词（如she,he）。

不是说一个句子中必须有动词么.那这句话怎样理解 Swimming is a good exercise. ( )fun and good exercise,swimming is a very useful skill _________being fun and good exercise,swimming is a very usef ( )fun and good exercise,swimming is a very useful skill. SWIMMING IS _____ A a good exercise B good exercise Cgood ex 英语句子中不只有一个动词吗?那这句话有几个啊有一个英语词组be hard to do,不是说一个句子只允许出现一个动词吗?那这句为什么有两个动词?be和hard this is good exercise 为什么不是this is a good exercise ? 一个简单英语句子,英语一句话中只能有一个谓语动词.I think he is a boy.这句话中think和is不都是 ()being fun and good exercise,swimming is a very useful skil （）being fun and good exercise,swimming is a very useful skil ______ being fun and good exercise ,swimming is a very usefu
