I'm so pleased to see that everything I wanted it to offer to the community is still here.”新的篇章听说经营了50年的彩虹书店要停业的那天,我的心都要碎了。这家书店曾是这片社区大名鼎鼎、固定存在的一家店,谁都可以来这里逛逛并因热爱书籍而互相认识。我匆匆赶到书店,看到那些书已经装箱了。我和老店主凯西聊了很久。他深深地叹了口气,告诉我经营独立书店越来越难。大多数年轻人更喜欢用平板电脑读电子书。越来越多的顾客被连锁店和网店折扣吸引。我想要说些同情的话,却发现自己不得不承认彩虹书店的确开不下去了。童年的回忆清晰地浮现在我的脑海里,好像那些事就发生在昨天。我们这群孩子放学后经常去书店。我们会看看新书,或者只是与老凯西聊几句。他对店里每本书都了如指掌,总能从落了灰的架子上挑一本最好的书给我们。我们会坐在店里陈旧而舒适的家具上,读上好几个钟头的书。凯西鼓励我们把对书的想法和评论分享出来,写在书店一角的大板子上。我离开书店的时候,外面已又冷又黑。我转身向凯西挥手告别,但他和书店都已经消失在浓雾中。这让我意识到,书店和老凯西给社区带来的一切都将很快消失殆尽。几个月后,我在春假期间回到了社区,却惊奇地发现彩虹书店仍然伫立在那里,并且还在营业。它外面的旧砖瓦丝毫未变,但里面却像一个不同的世界。店里开辟了一片阅读区。在阅读区附近,顾客们在货架前仔细地挑选着文具、海报和其他畅销主题的礼品。之前书店角落里的大板子换成了一个大屏幕,顾客对本月畅销书的评论展现在上面。显然,彩虹书店经营有方、富有创意。我听说是社区决定发起团结协作拯救彩虹书店的活动。这次活动由珍妮弗·奥克利领导,她是一位售货员,从小在社区长大,现在已经从凯西手中接手了书店。在珍妮弗的领导下,这家书店变成了社区文学爱好者聚会的地方。书店里有咖啡馆,出售有机食品;现在这里还举行更多的社区活动,比如读书会、诗歌朗诵会甚至是爵士音乐会和电影之夜。在这里,人们可以聚在一起分享体验,这种体验是无法从网上下载到的。我凑到凯西旁边,他正看着大屏幕上不断出现的读者评论。“嗯,正如你所看到的,集体的智慧和创意把我这个简陋的书店带进了21世纪!我很高兴,我想让书店奉献给社区的一切都还在。”THANKSPeriod 1 单元词汇表(Words and expressions)1.___________ n.十年;十年期 2.___________ adj.年老的 3.___________ n.一群,一伙 4.___________ n.搁板,架子 5.___________ n.家具 6.___________ n.薄雾,雾霭 7.___________ n.女销售员 8.___________ adj.简陋的 9.___________ v.强调 10.___________ n.新闻工作者;新闻记者 11.era n.___________ 12.reform n.___________ 13.initiative n.___________ 14.solid adj.___________ 15.component n.___________ 16.soul n.___________ 17.facilitate v.___________ 18.educator n.___________ 19.convincing adj.___________ 1.Tasting delicious,the fresh fruits were sold out as soon as they were put onto these________(shelf). 2.The animal has faced the danger of extinction in about several_____________ (decade),with the number shrinking to about 50. 3.Appropriate exercise is one of the key_________(component) of a healthy lifestyle. 4.The airport invested by the government________(facilitate) the development of local tourism in the near future. 5.The two_________(saleswoman) were busily trying to keep up with the demand. 6.In the interview,he________(emphasise) that a more effective way of treating the disease had been discovered. 7.Hundreds of________(educator) from across the country were meeting to discuss the need for greater cultural diversity in the school curriculum.1.sympathy n.同情→________adj.同情的;有同情心的→________v.同情;赞同 2.dust n.沙尘;灰尘→________adj.布满灰尘的 3.compete v.竞争→________n.竞争;竞赛;比赛→________n.竞争者;对手 4.construct v.建设→________n.建设→________v.重建;修复→________n.重建;修复 5.economy n.经济;节约→________adj.经济(上)的 6.expand v.(使)扩大;增加→________n.扩张;扩大 7.emotion n.感情;情绪→________adj.情绪(上)的,情感(上)的 8.intend v.打算→________n.意图,目的 9.adapt v.适应;适合→________n.改编版 10.urge v.敦促,力劝;竭力主张 n.强烈的欲望,冲动→________adj.紧急的→________adv.紧急地;急迫地→________n.紧急,迫切 1.Did you predict how many students would sign up for the dance________(compete) 2.About five weeks ago,I noticed the skin of our pet lizard(蜥蜴) was growing________(dust). 3.Youwouldbewelladvisedtodealwiththis problem_________(urgent). 4.My mother bought a book with the________(intend) of learning English. 5.The story is based on one of Richard Matheson's novels,and this is its third film________(adapt). 6.Popularizationhasinsomecaseschangedthe original meaning of_________(emotion) intelligence. 7.You have to be firm,but at the same time you should try and be________(sympathy). 8.After a few years of active________(reconstruct),many famous cities rose from the ashes of the war.1._____________顺道拜访 2.___________ 一群 3.___________ 向某人挥手告别 4.___________ 永远;永久 5.___________ 仔细打量某物,审视某物 6.___________ 由可信任的人负责(或处理等) 7.___________ 接管 8.___________ 突然出现,冒出来 9.___________ 详述,充分叙述 10.___________ 比……有优势 11.___________ 一串,一系列 12.___________ 蔓延至,扩散到 1.In such an era of the information explosion,you can never know what news will_____________on your computer screen. 2.The young man who was expected to___________his father's company made an unusual decision that he would start his own business. 3.In order to finish his paper,he spent several hours in the library___________ old documents. 4.He was upset that he injured one of his legs while playing football,which meant that he might leave the football field___________. 5.There is no need to treat me to lunch;
