although和though都有虽然的意思，两者的意思很接近，区别也不是很大，一般情况下可以通用。两者的区别是though可以用在句末，但是although不可以，即：Though,but not although can be used at the end of a sentence.
看个例子：
She knew all her friends would be there.She didn't want to go,though.
而且though除了虽然，还有别的意思，比如可以表示转折，意思是“但是”。
even though是“即使”的意思，等同与“even if”
追问那even though后面能不能加but
