Art Period 2 Language Study
这是一个倒装句，主句是among the painters were the impressionists。who broke away from the traditional style of painting 是由who引导的限制性定语从句，修饰the painters。who lived and worked in paris是由who引导的非限制性定语从句，修饰the impressionists。
2.there are scores of modern art styles，but without the impressionists，many of these painting styles might not exist.(p3)
现代艺术风格已经有好几十种，然而如果没有印象派，那么这许多不同的风格就不可能存在。
在but连接的并列句中，由without引导的介词短语是一个暗含的非真实条件，相当于if there were not the impressionists；主句用虚拟语气might not exist。
