When enter rome do as the romans do. 　　(1)as从句带有比喻的含义，意思是"正如…"，"就像"; 　　(2)as if/though："仿佛……似的"，"好像……似的"; 有时用虚拟语气，有时不用; eg：They completely ignore these facts as if (as though) they never existed. (与事实相反，谓语用虚拟语气。) He looks as if (as though) he had been hit by lighting. (与事实相反，谓语用虚拟语气。) It looks as if the weather may pick up very soon. (实现的可能性较大，谓语用陈述语气) 　　(3)the way：可以连接两个句子，表达就像……一样; 　　eg：I should do the job the way my father did. Many Europeans now apparently view the US. the way many Americans view Mexican as a cheap place to vacation, shop and party. (4)what：就像，犹如; 　　eg：Air is to man what/as water is to fish.

　　句型：A is to B what C is to D. eg：A1 Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. put sb. on a path to a solution：找到解决的办法。
