尽管这个问题很难,但他都不会轻易放弃.英语怎么写啊

Although the problem is very difficult,he dosen't give up.
although不能和but连用，这是对的
另外还有一种说法就是：
The question s very difficult,but he doesn't give up.
这个问题可以用the表示，不需要用this,在英文中the已经表示特指这了。
but和altogher可以互相转化句型。。。

Although this question is very difficult, but he all cannot easilygive up .

Although this problem is difficult,he dosen't give up.
although不能和but连用
