curious 的用法
Children are usually curious ____ the pain by taking out the tooth.
这里为什么不是about、不是about是什么?

as to

也可以用I am curious about what she will say. 在这个句子当中curious as to与curious about看上去用法没什么区别。但是,当两者后面接的成分发生变化后

千真万确,是about,查了牛津英汉词典,无其他合适用法.
但是句子本身读起来不是很顺,是不是指Children are usually curious about the pain (caused) by taking out the tooth.
