连词but,however,although和while的用法1
1. but 连词，“但是”。
用来引出微弱的反对意见，是口语中的常用词。
例如：I was going to write, but I lost your address.我本来要写信的，可是把你的地址弄丢了。
2. however ①副词，“可是；不过；然而；无论如何；不论到什么程度”。
however比but的词义还要弱些，并不直接引出相反的意见，因此，常用作插入语。
例如：I’d like to go with you; however, my hands are full.我很想和你一块儿去，可是我忙不过来。
②连词，“不管用什么方法；无论什么方式”。
例如：However I cook eggs, the child still refuses to eat them.不管我用什么方法做鸡蛋，小孩还是不肯吃。
3.although 连词，“虽然；尽管”。
although与though大致相同，口语中though比较常用。
例如：Mr. Hall understands that although maths has always been easy for his son, yet this problem is not easy for him.Hall先生明白，尽管数学对他儿子来说一直很容易，但这道题对于他来说并不简单。
4. while 连词，“但；却；然而”。
它表示对比或相反的情况。
例如：You like sports, while I prefer music.你喜欢体育，而我更喜欢音乐。

• 间接引语也学习过。要注意的是间接引语中主句 时态和从句时态的一致性原则。一般来说，如果 主句谓语动词为过去时，在将直接引语变为间接 引语时，要将直接引语中的谓语动词时态往前推 一个时间档，即一般现在时变为一般过去时，一 般过去时则变为过去完成时，看下面的例子：
• 由于although的中文意思是“虽然……，但 是……”，很多学员容易犯的一个错误是用了 although后，又用but，这在英语里是错误的。
• however表示转折，与but意思相同，但是较正式 的说法。However在句中位置较灵活，在句首时， 后面常用逗号。
• 如：He was wealthy. However, he was very mean(吝啬的).
