[探究](1)unless用作________词，相当于“if…not”。由unless引导的________状语从句中，谓语动词只能是肯定式，表示强烈的否定条件；它也遵循“主将从现”的原则，即主句是一般将来时态，从句用一般现在时态。(2)本句中宾语从句在think之后，且主句的主语又是第________人称，在否定从句时，句子的否定体现在________句中，这种现象叫否定前移。遵循“否定前移”的其他常用单词还有suppose,believe,expect等。连条件一主Lesson27

[探究](1)worth作________词，意为“值得……的”。“beworth＋n.”意为“值……”；be(well)worthdoingsth.意为“(很)值得做某事”。Thisbookisworthreading.这本书值得一看。Thefilmiswellworthseeing.这部电影很值得看。(2)evenif引导________状语从句，意为“即使；纵然”。形容让步Lesson27

PlanetDanny[拓展]although,though,evenif和eventhough都表示“虽然，即使，尽管”，且都可以引导让步状语从句。although和though语气较弱，evenif和eventhough带有强调意味且语气更强。Althoughitwasverycold,hewentoutwithoutanovercoat.虽然天很冷，但他没有穿大衣就出去了。Eventhoughitwasraining,shewalkedtowork.即使下着雨，她也走着去上班了。[注意]although,though,eventhough,evenif均不与but连用，但可以和yet连用。3．(1)2017•恩施电视节目《最强大脑》很值得一看。TheTVprogramSuperBrainiswell________________．worthLesson27
