常犯错误

✗ Although he is young, but he knows a lot.

✓ He is young, but he knows a lot.

✓ Although he is young, he knows a lot. 虽然他年轻，但是他懂得不少东西。

[✌although/though不可和but连用。但汉语里“虽然…但是”常连用。]

用法but后接动词的形式

如果谓语是do这个词，but后接动词原形，如果谓语不是do而是其他动词，则but后接动词不定式。如：He did nothing but wait. 与except, than后接动词的形式类似。
