他这里问的是What's in the lake?有什么在湖里?
回答是：Some boys.(一些男孩）
在这里swimming in the lake,是表示伴随,而不是你所理解的Some boys are swimming in the lake.(有一些男孩正在湖里游泳）
也就是说,这里的swimming in the lake,不是用作谓语,而是用作状语
你还可以这样想：如果你的回答是Some boys are swimming in the lake.那就答非所问了

他为什么的是湖了有什么
答案应该是湖里有些男孩，有些游泳的男孩
swimming 是非谓语
即some boys who are swimming in the lake

省略了. 这是口语,越简单越好.这是习惯.比方说,你吃饭没有,你肯定会说,吃了,而不是我吃饭了.对吧.

are swimming
yes
correct

因为问的是What
你只能回答名词Some boys swimming in the lake
swimming分词作定语

是SWIMMING 整句应该是THERE ARE Some boys swimming in the lake 所以不需要ARE
