1、Unit5 Firstaid主旨大意题之段落大意题(阅读理解)方法指导由于文章的结构不同,主题句出现的位置通常也不同:(1)采用归纳法撰写的段落,表述的事例在前,概括性的观点居后,主题句则位于段末。(2)运用演绎法撰写的段落,先提出观点,后举例论证,主题句则出现在段首。(3)如果作者采用事例——观点——事例的写作方式,则主题句出现在段落的中间。(4)如果文章没有明显的主题句,则根据内容的提示,通过逻辑推理,概括出主题句。做这类题时需快速阅读文章,找出各个段落的主题句。一般来说,说明文和议论文都有主题句,而且多位于文章的开头,有时也位于文章的中间或末尾。但有时不能直接在文章中找到
2、主题句,那么则需要在弄清段与段之间逻辑关系的基础上自己归纳总结。主题句必须能简洁明了地概括全文的主要内容,具有高度的综合性和概括性,文章的其他句子都是对主题句的进一步解释、说明、论证或拓展。典例引领(2017浙江,A)BenjaminWest,thefatherofAmericanpainting,showedhistalentforartwhenhewasonlysixyearsofage.Buthedidnotknowaboutbrushesbeforeavisitortoldhimheneededone.Inthosedays,abrushwasmadefromcamel
