You come from English or china和I need take a shower是病句吗

都是病句
第一个句子，意思上明显不对，什么叫做“你来自英国或中国。”并且那个English是形容词，作名词也是英国人，英语的意思。
第二句中的need后面一定要是动词不定式。当need是情态动词时，只能够用于一文举或者否定句

是，English是作英国人，英语，英国人的讲，应该改成England

第2句两个动词挨着会打架，改成i need to take a shower
当need做情态动词（When used as an auxiliary verb,need does not agree with its subject, does not taketo before the verb following it, and does not combine withdo）多用于否定句, 疑问句; 过去时用 had to, 将来时用 will [shall] have to]需要; 必须, 不得不，如You need not come today.

应该是这样

where are you from,england or china?

Would you like to take a shower?

You come from China
I need to take a shower

完全正确，不过China得大写，小写是陶瓷的意思
