大家好 有关although 和 but 一般文法书都会说二者不能并存 但我看Charles Harrington Elster的Verbal Advantage里头 Level 6的 Word 6中有一句话是 As I noted in the first half of the program, if you want to learn more about the world and learn more words, then reading is the best way to edify yourself. But even entertainment can be edifying, although some forms of entertainment,such as watching reruns of "Wheel of Fortune," probably won't edify you at all. 这里but even和although,已经并存@@ 请问这样的写法是否有其他的文法规则,而我没有想到? 谢谢
