This dress is ready except for the buttons. 衣服做好了，只是钮扣未缝上。(句中ready与buttons不同类)

This dress is ready except for the buttons. 衣服做好了，只是钮扣未缝上。(句中ready与buttons不同类)

你好。不要再纠结了。读完了以下言论，你就明白了：
1 except----定义是：除了A没有B
------All came except Mary, who was too ill to come (注意：all与Mary在身份地位种类和属性上是相同的，这时候就用except)
2 besides----定义是：除了A以外还有B
---------Four other boys were late besides Tom and me (注意：four other boys 与Tom and me 在身份地位种类和属性上是相同的，这时候就用besides)
3 except for-----定义是：整体与部分的关系
--------This flat is very good except the small kitchen (the small kitchen是this flat的一部分)
--------- i am quite well except for a slight headache (a slight headache是“我”的一部分)
4 except that ------定义是：+句子
-------This flat is very good except that its kitchen is a bit too small, which is a pity.

现在，你明白了吗？呵呵。简单吧？追问按你的说法，The pair of trousers fits me well ___except_____ the waist of it is a little too small. 这句话就改成except for。

--------This flat is very good except the small kitchen (the small kitchen是this flat的一部分)
--------- i am quite well except for a slight headache (a slight headache是“我”的一部分)
而且你的这两句都是整体与部分的关系，怎么一个是except,一个是except for，求赐教。追答你好。不好意思，是我漏打了-----------------This flat is very good except the small kitchen ---------应该是：--------This flat is very good except FOR the small kitchen (the small kitchen是this flat的一部. 影响你的思维了，对不起。追问except for后接的词同句子中的整体词（主语）不是同类的，指从整体中除去一个细节，一个方面；而except后接的词同整体词（主语）一般是同类，指在同类的整体中除去一个部分。

网上流传的这句话This dress is ready except for the buttons. 衣服做好了，只是钮扣未缝上。(句中ready与buttons不同类) ，句子虽对，解释是错的。应该是（句中This dress与buttons不同类，且指从整体中除去一个细节)追答应该是整体与部分的关系，也就是你说的整体中除去一个细节。
