问题：except怎么用?except后面的事物是与前面属同一类的Th 
except 后面的事物是与前面属同一类的These artic are very good except this article.except for后面的事物是不与前面属同一类的These articles are very good except for some sentences.那么except that 后面的句子里的名词是与前面属同一类的么?还是无约束的?举个例子
回答：都可以，无约束的
只是except that后面加从句，而前两个只能加名词或短语。
例如
These articles are very good except that this article is not good.
These articles are very good except that some sentences are wrong.
