but 和though

though and but都有转折的作用，但在一个具体的句子中,两个连词只能保留其中的一个。例如：
We are from different countries,but we all get along(相处)well.
Though we are from different countries,we all get along well.
Chen and Huang are Chinese, but they are not from China.
They're from Malaysia. They're overseas Chinese(华侨).

because和so两个连词也是如此，前面使用了because，后面就不能出现so。后面出现了so，前面就不能出现because。例如：
Because the Wangs are such goog neighbors，I am lucky.
The Wangs are goog neighbors，so I am lucky.

Although和but也同样呀！例如：
Although the people were friendly，I missed my family，my friends and the lifestyle in my hometown.
虽然那里的人们都很友善，但我还是想念故乡的家人、朋友以及生活方式。
The people were friendly，but I missed my family，my friends and the lifestyle in my hometown. 意思也相同吆。

##but(常用以引出与前文相对照或修饰前文的词语）
eg.Tom went to the party ,but his brother didn't.
（汤姆去参加聚会了，他的弟弟却没去．）
@@though(用以引出位于句末的从句）
eg.He'll p
