she seems upset? 如果是why引导的问句这样对吗？why she seems upset?

she looks upset我觉得更通顺,呵呵

不过seems to be upset也是okay得

why does she seem to be upset?

why does she look so upset?

silverinch的答案是比较书面的！就是没有语法错误的，如果是在考试或者比较正式的环境，就应该这麼用. 不过如果是口语的话，lz的表达就是正确的

如果是特殊疑问句，你的写法不正确。
可以加个助动词使句子完整。
Why does she seem upset？

Why does she seem upset?

没错的。
