44、 Dstop20Aignore BtakeCwatch Dnotice2021/8/11 星期三69【答案与解析】【文章大意】本文讲述了对美国人来说比较敏感的一些话题,比如:年龄,体重,薪水等等。因此,在同美国人谈话时要“三思而后行”。1B【解析】subject“科目,主题,话题”。句意:年龄对于许多美国人来说是一个很敏感的话题。下文“Weight.This is one of the most sensitive subjects.”是提示。2021/8/11 星期三702B【解析】if possible“如果可能的话”。句意:在美国文化中,一想到变老人们就会觉得很痛苦,而我们中的大多数人,

45、如果可能的话,会不在意年龄大小。3D【解析】keep“保持”。句意:美国人会努力保持年轻的容颜。2021/8/11 星期三714A【解析】reply“回复,答复”。句意:这个问题可能会收到这样的答复:“你认为我多大了?”5B【解析】be eager to do sth.“渴望做某事”。此处指如果你真的很渴望知道一个人的年龄。2021/8/11 星期三726C【解析】此处指通过他们的外貌来估计他们的年龄。appearance“外貌,容貌”。7A【解析】根据“that person will probably say,Thanks,but I am a few years older than t

46、hat.”可知,当美国人被别人认为自己比实际年龄小的话会是很高兴的,因此选smile,with a smile指面带微笑,此处指美国人笑着说。2021/8/11 星期三738 C【解 析】根 据 下 文“In any American fashion magazines,youll notice most _10_ are nothing more than skin and bones.”可知,美国人以瘦为美,因此此句句意为:在美国,人们都渴望变瘦,而如果一个人很胖,这将是很尴尬,很耻辱的。9D【解析】见上题解析。2021/8/11 星期三7410D【解析】根据“American fashi

47、on magazines”可知,在时尚杂志上的模特都是瘦得皮包骨头。其他三个选项分别意为:歌手;编辑;作家;都不符合题意。11A【解析】salary属于Income的原词复现,这两个词均意为“薪水,收入”。2021/8/11 星期三7512B【解析】前一句意为:你永远都不应该问一个人的薪水是多少。However表转折,说明此句意思和前一句相反,因此询问美国人他们的工作是合适的。13A【解析】pour out“倾倒”。句意:有些人迫不及待将他们的心事吐露给你。14C【解析】personal business“私事”。句意:而有些人会确保他们的私事得以保密。2021/8/11 星期三7615B【解

48、析】general rule“基本原则”。句意:谈话的基本原则是不要谈论比较私人的事情。16C【解析】look into“调查”。句意:你不希望别人认为你在调查他们的生活。17B【解析】此句和前一句之间为顺承关系,故用Besides表示“另外”。2021/8/11 星期三7718D【解析】句意:除非你和这个人交了朋友,否则,别问太多问题。19A【解析】句意:在谈话中经常避免尴尬的话题是困难的。20C【解析】watch your mouth指注意你的言行。2021/8/11 星期三78.阅读理解记叙文的阅读【技巧点拨】记叙文是按照一定的时间顺序记叙事件发生过程的一种文章体裁,讲故事、说笑话、谈经

49、历、忆历史、人物传记、新闻报道、内容详实的日志等都属于记叙文的范畴。在读记叙文时要抓住几个要素:时间、地点、人物、事件、结果,还要注意人物之间的关系、作者的写作意图以及文章的寓意。能否抓住这几个要素,是做好细节题的前提,也是写好记叙文摘要的关键。2021/8/11 星期三79【活学活用】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。It was Mothers Day morning last year and I was doing shopping at our local supermarket with my fiveyearold son,Tenyson.As
