A．Who to boil the eggs. B．How to cook the eggs. C．What to cook for breakfast. [Text] W：Would you like me to fry the eggs or just boil them for your breakfast? M：I'd like them boiled.But don't boil them for too long. [分析]　根据听力中“like me to fry...or...boil...”我们可推出A项不正确；同时，对话双方都心知肚明的食物是“eggs”，因此C项不正确，因为食材是确定的，只有B项正确，如此做“鸡蛋”，二选一，是“fry”还是“boil”，故选B。 　What are the speakers mainly talking about? A．A storm. B．A flood. C．A garden. [Text] W：Peter，were you all right last night? M：Oh，what a night! The trees in my garden were blown down.It rained 8 centimetres in one hour.It's the biggest storm I have ever experienced. [分析]　该题需要学生进行概括归纳。“花园”被“blown down”，1小时下了8毫米深的水；是“我”所经历的最大的“暴雨”。都与“暴雨”有关，围绕“暴雨”说明“雨大”，危害也大，故选A。 　What are the speakers talking about? A．Seasons. B．Photos. C．Animals. [Text] M：I love the photos in your room.Did you take them? W：Only one of them.It's the forest in winter. M：The one with the snow falling on the horses? W：My dad took that.There aren't any animals in mine but there's snow everywhere. [分析]　该听力材料中多次重复与“photos”同一范畴的词，“them”，“one of them”，“the one，mine”等。故选B。 [重点词汇] 1．flood n.洪水，水灾 vt.& vi.淹没；(洪水般地)涌进；涌出 (1)in flood 　在泛滥 a flood of　大量的 (2)flood...with...　使……充满(常用被动语态) flood in/into　大量涌入(某处) [经典佳句] The River Nile used to be in flood regularly every year. 尼罗河以前每年都定期泛滥。 There was a flood of complaints about the bad language after the show. 演出结束后，人们对其语言之拙劣议论纷纷。 [即学活用]　单句语法填空/翻译句子 ①The golden sunlight flooded ____ my room. ②Japanese companies were accused of flooding the market ____ cheap steel. ③一阵兴奋的浪潮席卷了我。 A wave of excitement took hold of/seized/ ____________/swept over me.(无灵主语句) ④每年，大批的农民到达深圳找工作。 _______________________________________________________ 2．comment n.评论；意见 vi.& vt.表达意见；评论 (1)comment on/about 　对……评论 comment that...　评论说…… (2)make/give comments on/about sth　评论某事 no comment　无可奉告 [经典佳句] He commented that it was an excellent film. 他评论说这部电影很精彩。 He made/gave a comment on/about my performance. 他对我的表现进行了点评。 [即学活用]　单句语法填空/完成句子 ①I came back with my first jars of zero waste groceries，and my dad commented __ how silly it was for me to carry jars everywhere.
