1. The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. (P2)
【归纳】 look forward to盼望，期待。
【延伸】 look up... in查找；look back on / upon回顾； look through浏览，看穿； look down on / upon 俯视，蔑视；look into窥视，调查。
【易错点】 look forward to作“盼望，期待”讲时，to是介词，后面跟名词、代词或动名词。还有些to作介词的短语，如：be(get) used to, devote to, object to, subject to, get down to, refer to, stick to等。
