內容簡介
一、穿透安徽考情,才能劃準重點
知己知彼,才能百戰不殆。考試就如同作戰,在迎戰中考前,要全面深入地分析安徽歷年的中考化學考試情海幾影凝況,才能從眾多知識紋境盛點和考點中準確劃出考試重點,提高備考效率,最終達到良好的備考效果。因此,本書一開始就從國中化學教材和國中化學課程標準、近15年安徽中考化學試卷、全國新中考考情這三個維度,對安徽中考化學的考情進行了深度研析,艱勸巴有利於幫助大家穿透安徽中考化學的考情,抓准考試的重點。
1. 深入研析教材與課標,劃準重點
國中化學教材和國中化學課程標準是同學們學習知識點的來源和基礎,在“教材知識點梳理”這一版塊中,我們從課題出發,梳理出教材及對應課標的知識點,列出了每個單元的“科學探究”。此外,還補充了人教版教材中沒有但課標中要求掌握的知識點,幫助大家全面複習、打好基礎,明晰重點知識。
2. 深入研析中考試卷,劃準重點
試卷研析,是分析考情的關鍵,在本書的試卷分析部分,我們以安徽中考化學試題改棕嫌兇埋革前後的變化為討論基點,從試卷結構、試卷難度和試題內容三個層面,分析了安徽中考化學試卷的結構變化、分值變化、題型變化以及考點考頻變化情況。同時,在《課堂講練》的第二、三、四部分,分別對各個單元、專題、題型都設定了對應的“理考情”版鞏盼旬塊,幫助大家從巨觀和微觀兩個角度全面深入少鑽巴地分析考情,準確把握重點。
3. 深入研析全國新中考考情,劃準重點
安徽中考化學的命題在核心思想上與全國新中考一脈相承,通過分析近3年的全國各地市中考試題,我們發現命題趨勢呈現出:題乾更新穎、重視實驗探究、與生活聯繫緊密的特點。安徽中考化學的命題在此基礎上,更注重體現學科素養,培養學生終身受用的核心能力與品質。在《課堂講練》和《課後練習》的相關題型中融合了化學學科核心素養,激發同學們的思維能力和分析問題的能力,從巨觀和微觀相結合的視角分析並解決問題,把握重點題型的命題趨勢。
綜合以上三個維度的考情分析,《中考響雲箭化學總複習》將安徽中考化學聚焦在“劃重點考點、講重點題型”兩個方面。
二、劃重點考點,快速備考
為了幫大家更好地學習重點知識,我們根據課標要求和考情分析,以國中化學教材為基礎,在《課堂講練》的“第二部分中考考點精講”中,對12個單元進行了系統梳理,以思維導圖的形式列出本單元的知識點,再從中挖出若干個考點,做到快速複習無遺漏。
另外,根據對近15年安徽中考化學真題的分析,在每個考點後面標註出“高頻”“中頻”和“低頻”,使大家對各個考點的重要程度一目了然。還對一些考點進行了規律總結和知識補充,幫助大家快速掌握知識、明確重點學習方向。考點後的習題訓練,幫助大家及時鞏固考點知識,提高複習效率,快速備考。
三 講重點專題和題型,快速備考
通過研究國中化學教材,我們梳理出了教材中的重難知識,發現在近15年的安徽中考化學試卷中,這些重難知識所占的分值較大。所以,在《課堂講練》的“第三部分 重難專題強化”中,我們將重難知識整合併劃分成7個重點專題進行集中強化。通過分析各專題下的多個考查類型,以及進行相關習題訓練,幫助大家快速掌握中考重點的考查類型。專題講解的形式,還將多個知識點融會貫通,提高備考效率。
掌握了知識,還要學會解題方法。在《課堂講練》“第四部分 題型專項突破”中,講解了各個題型的解題方法,並設定習題練習,幫助大家提高答題正確率,從而快速複習。
四 分層練習,基礎補漏,快速鞏固
複習了重點知識之後,在備戰中考的過程中,還需要進一步的進行分層練習和梳理基礎知識,幫助大家快速鞏固,查漏補缺。《課後練習》包含“單元綜合練”和“題組專項練”兩個部分,分別從由淺入深的習題設定,以及多種題目類型的練習這兩個維度進行分層訓練,不僅鞏固基礎,還提高解題效率。《考前記背》梳理總結了國中化學教材中的知識點,將零散的知識點系統化,幫助大家快速回顧知識點,夯實基礎知識。《易錯專項》將安徽中考化學中常見的易錯知識歸納為四大類,幫助大家快速明晰考喇市試中的易 錯點。
