although區別 whereas

wheares和although的區別如下：

whereas有兩個常用的意思，一個是“鑑於”，一個是反之。是連詞。Whereas I tend to take a faster train for the meeting， they tend to leave a day early. 他們想早走一天去開會，我卻傾向於坐個快點的火車。

1、although較正式，語氣強

Although he was tired，he went on working.

2、although引導的從句放在主句前後均可，有時還可放在句中.

Although many difficulties are still ahead，we are determined to make greater achievements.儘管在前面的道路上還有許多困難，但是，我們決心要取得更大的成就.

He often helps me with my English although he is quite busy.儘管他相當忙，但是還常常幫我學英語.

3、although引導的從句不能與but，however連用，但可與yet，still連用.不能說：Although he was old，but he worked hard.應把but去掉.當然，保留but而去Although也可.

注意:although 的幾不:

although不能指假設的情況

although不能作並列連詞

although不能作副詞，放在詞尾
