1）大家都很熟悉 although 是 “虽然，尽管” 的意思，但要注意， although…but 是一个语法错误：
Although 就暗示着后面有一个转折，无需再加一个 but
Although I am very tired, I am still gonna go to the party. 虽然我很累，我还是要去参加派对。
even though，though，这些词也有 “虽然、尽管” 的意思，它们的后面也不能加 but
although，even though，though 的区别只在于位置：
although 放在开头，but 放在中间，though 后面。
I was very tired, but I went to the party. 我很累，但我还是去参加派对了。
I am very tired, I am still going to go to the party, though. 我很累，但我还是要去参加派对。
though 如果放在中间，听起来就很正式甚至带有一些诗意。
although，even though，though 后面不能加 but 但是可以加 still， 可加可不加，但加上之后转折会显得更加明显。
Although I was full, I still finished the dessert. 虽然我饱了，但我还是吃完甜品了。
4）although 可以用于过去、现在，也可以用于将来时：
Although it will rain, my son still needs to go to his soccer practice. 尽管会下雨，我儿子还是要去足球训练的。
这两词里面都有spite，spite 有战胜、赢得某事后，对某事不在乎，将其视为不重要，某事难不倒某人的意思：
Despite leaving late, I still got here on time. 尽管出发晚了，我还是按时到达了。
In spite of the bad traffic, I still got there on time. 尽管交通很堵塞，我还是按时到达了
这两个词后面都不加 but，但是可以加上 still：
Despite her mom’s objections, she still married him. 尽管她妈妈反对，她还是嫁给他了。
despite, inspite of 两者的区别是：
despite 可以加名词，也可以加动名词，但 in spite of 通常只能加名词
despite leaving late：尽管迟出发
in spite of traffic：尽管交通堵塞
当 while 意思的“在……期间”时：
While I was working, my son was sleeping. 我在工作的时候，我儿子在睡觉。
当它的意思是“尽管”，指虽然 A 事情成立，但是还有 B 需要注意：
While he is competent, he is not outstanding. 尽管他很能干，但他并不出色。后面也不能加 but
有人说分不清 even though 和 even if，两者区别在于：
even though 后面跟的是事实, even if 后面是假设。
The football game will go on, even if it rains. 即使下雨，足球比赛也会继续进行。
Even though it's raining , the game has been continued. 尽管下着雨，比赛还是继续进行。
