B: Sure. I went to a mountain village last summer. It was totally different from ten years ago. A: How has it changed? B: In the past, there were only rough dirt tracks. People worried about food shortage and a lack of clean water. A: So great progress has been made over the years? B: Exactly. With the government’s support, new roads link the village to the town, and it has become a popular tourist attraction. 对话译文 A：你曾经去过乡村旅行吗？ B：当然。去年夏天我去了一个山村。它和十年前完全不一样了。 A：它发生了怎样的改变？ B：过去，这里只有崎岖的土路。人们担心粮食短缺以及饮用水不足。 A：这么说这些年取得了巨大的进步？ B：没错。在政府扶持下，新公路把村庄和城镇连接起来，这里也成了热门旅游景点。 3a 阅读原文 Our Hometown Is Changing Great changes have taken place in our hometown over the years. In the old days, many hills were covered with sand. There were no wide roads, only narrow dirt tracks. It took people a long time to reach nearby towns. A lack of farmland made many young people leave for big cities to make a living. Now everything is different. Workers planted many trees on the hills. They have long roots that can hold the soil together. The government built new highways to link villages with cities. More tourists come here every year, and our hometown becomes a well‑known tourist attraction. We are proud of these changes, and we hope our hometown will have a brighter future. 阅读译文 我们的家乡正在改变 这些年来，我们的家乡发生了巨大的变化。 过去，许多山丘被沙土覆盖。没有宽阔的公路，只有狭窄的土路。人们要花费很长时间才能抵达附近的城镇。耕地不足使得许多年轻人前往大城市谋生。 如今一切都不一样了。工人们在山丘上种植了大量树木。树木长长的根系可以固住土壤。政府修建新公路将乡村与城市相连。每年越来越多游客来到这里，我们的家乡成了一处著名的旅游景点。 我们为这些变化感到自豪，也期待家乡拥有更加美好的未来。 板块2：核心重难点单词精讲 1. rough /rʌf/ adj. 教材原句：Going to school by bus took over rough roads. 本义：（道路）崎岖不平的 变形：roughly adv. 粗略地；大约 中考熟词生义：①（计划、方案）粗略的、不完善的（完形高频）②（生活）艰苦的 重难点搭配：rough roads 崎岖土路；a rough plan 不完善的计划 易错陷阱：勿混淆tough (adj. 艰难的、坚韧的)，形近词必考辨析 考点例句：The rough village plan needs to be improved. 2. shortage /ˈʃɔːtɪdʒ/ n. 教材原句：They worried about food shortage years ago. 本义：短缺，不足 变形：short adj. 短缺的；短的 重难点辨析：short（形容词）≠ shortage（名词） 必考搭配：a shortage of water/farmland 缺水/缺耕地 易错陷阱：名词短语必须加不定冠词a；形容词short搭配短语be short of 3. lack /læk/ v. & n. 教材原句：There was a lack of clean drinking water. 本义：缺少、缺乏 重难点双词性考点： ① 名词：a lack of + 名词（必考，无复数） ② 动词：lack + 名词（直接接宾语，不加介词，高频改错点） 易混辨析：lack (v.) = be short of (adj.短语) 4. root /ruːt/ n. 教材原句：It had long roots that could hold the soil together. 本义：植物的根 中考熟词生义：（问题、矛盾的）根源、起因（阅读/完形核心考点） 必考搭配：the root of the problem 问题的根源 写作高阶例句：We must find the root of environmental problems. 5. support /səˈpɔːt/ v. & n. 教材原句：The government gave us lots of support. 本义：v.支持；n.扶持、帮助 中考熟词生义：v./n. 承重、支撑（物体） 重难点变形：supportive adj. 支持的 必考搭配：get support from the government 获得政府扶持 6. attraction /əˈtrækʃn/ n. 教材原句：Our village becomes a tourist attraction. 本义：吸引力 变形：attract v. 吸引；attractive adj. 迷人的 中考最高频熟词生义：tourist attraction 旅游景点 7. track /træk/ n. 教材原句：In the past, there were only dirt tracks. 本义：乡间土路、小径 中考熟词生义：跑道；轨道（完形辨析高频） 8. link /lɪŋk/ v. & n. 本义：v.连接；n.交通干线 必考搭配：link A to/with B 把A和B连接起来 时态考点：常考一般现在时、现在完成时被动语态 9. capital /ˈkæpɪtl/ n. 本义：首都 中考熟词生义：资金、资本（拓展阅读难点考点） 10. wide /waɪd/ adj. 本义：宽阔的 变形：widen v. 拓宽（词形填空必考） 熟词生义：范围广泛的（wide knowledge 广博的知识） 板块3：重难点短语分层汇总 【核心必考易错短语】 1. used to do 过去常常（现在已不再，时态辨析核心） 2. be used to doing 习惯于做某事 3. be used to do 被用来做某事（三组短语辨析为本课最大短语难点） 4. be covered with 被……覆盖（绝对不用by，改错高频陷阱） 5. a lack of 缺少……（名词短语，写作、填空必考） 6. over the years 多年以来（现在完成时专属标志词） 7. many years ago 多年前（一般过去时专属标志词） 【阅读&完形高阶短语】 1. hold the soil 固土 2. government support 政府扶持 3. take place （有计划）发生 4. tourist attraction 旅游景点 【写作重难点加分短语】 1. bring great changes to… 给……带来巨变 2. improve people’s lives greatly 极大改善民生 3. link villages to cities 城乡互通 板块4：教材核心重难点句型 1.
