天津市2018年中考英語(yǔ)試題及答案天津市2018年中考英語(yǔ)試題及答案天津市2018年中考英語(yǔ)試題及答案資料僅供參考文件編號(hào)：2022年4月天津市2018年中考英語(yǔ)試題及答案版本號(hào)：A修改號(hào)：1頁(yè)次：1.0審核：批準(zhǔn):發(fā)布日期：初中英語(yǔ)的學(xué)習(xí)方法1：?jiǎn)卧~的記憶。其實(shí)英語(yǔ)的學(xué)習(xí)歷來(lái)都把單詞的學(xué)習(xí)作為重點(diǎn)，初中也不例外。我們一定要記住，單詞記憶切忌孤立地，單純地背誦單詞。我們中學(xué)最習(xí)慣的背誦方法就是背拼寫，比如what這個(gè)單詞我們一般都是這么背whatwhat，這樣只是記住了幾個(gè)孤立的字母而并沒有記住單詞，過(guò)不了幾天就會(huì)把這個(gè)單詞忘掉。那么我們就要把單詞放在一個(gè)整體或者環(huán)境中背誦，比如我們不如記住下面一句話：Whatisyourname(你的名字叫什么)那么就不容易忘掉了。也就是說(shuō)每記一個(gè)單詞都要相應(yīng)地記住用這個(gè)單詞在內(nèi)的一個(gè)例句，因?yàn)閱卧~的意思只能在句子中體現(xiàn)，有意思我們才不容易忘掉，而孤立的無(wú)意思的不容易記住。另外記憶單詞要利用一切可能的辦法去記住，比如分類記憶：我們把動(dòng)物的有關(guān)詞匯放在一起，把有關(guān)校園的有關(guān)詞匯放在一起，或者天文，地理，等等。當(dāng)然我們也可以利用諧音的方法自己編寫些小段子記住單詞。2：語(yǔ)法的學(xué)習(xí)。初中是開始學(xué)習(xí)系統(tǒng)語(yǔ)法知識(shí)的重要階段。這階段語(yǔ)法學(xué)習(xí)好了，以后語(yǔ)法就會(huì)感到很輕松。首先應(yīng)該明確是初中的時(shí)候我們學(xué)習(xí)的更多的是詞法而不是句法，因?yàn)楫吘箯暮?jiǎn)單開始吧，就算是中考題也基本上沒有多少句法的題，所以初中一定要把重心放在詞法上，就是名詞，介詞，冠詞，代詞，形容詞等上面，而這些東西是最零碎的也是最頭疼的，我們就更要有細(xì)心和耐心。建議每學(xué)習(xí)一個(gè)語(yǔ)法點(diǎn)，在學(xué)校教室里抄過(guò)一遍筆記后，回家靜下心來(lái)，再重新整理一遍筆記，去粗取精，這其實(shí)是回顧溫習(xí)的過(guò)程，并且要做好分類，不同重要程度的或者難易程度的要用不同的顏色區(qū)別對(duì)待，并時(shí)常翻閱。此外課堂上的語(yǔ)法知識(shí)往往和教材同步而并不系統(tǒng)，我們還可以再有一本語(yǔ)法書籍，甚至可以買高中語(yǔ)法，這樣有知識(shí)的拓展。3：文章的學(xué)習(xí)?，F(xiàn)在的教材文章普遍較難。所以閱讀文章難度是相當(dāng)大的。學(xué)生在學(xué)習(xí)文章前一定要預(yù)習(xí)老師即將要講的內(nèi)容，事先把自己認(rèn)為比較難的單詞語(yǔ)法和句子劃出來(lái)，這樣就可以有的放矢。課本上的文章一定要精讀，不能說(shuō)看懂了就可以，而是要把每一個(gè)重要的單詞和句子都要吃透。同時(shí)對(duì)文章中的經(jīng)典詞匯和段落要記筆記，甚至要會(huì)背誦，為后面的寫作打基礎(chǔ)。加強(qiáng)英語(yǔ)學(xué)習(xí)，閱讀是重點(diǎn)，課堂上的文章太過(guò)教條和局限，可能缺乏生動(dòng)性和樂(lè)趣性。因此課后也要多讀些課外文章。建議讀些國(guó)內(nèi)出版的淺顯的英語(yǔ)文章，比如象“英語(yǔ)沙龍初級(jí)版”英漢對(duì)照著看，一定會(huì)有興趣和提高。4：寫作的學(xué)習(xí)。寫作學(xué)習(xí)請(qǐng)大家牢牢記住下面兩句話。“讀書破萬(wàn)卷，下筆如有神”，“熟讀唐詩(shī)三百首，不會(huì)做詩(shī)也會(huì)吟”，強(qiáng)大的閱讀功底是寫出好文章的保證，只有輸入得多了才能輸出得多，因此一定要多讀課外文章還有精讀文章。在具體聯(lián)系方面，我們并不需要寫太多字?jǐn)?shù)的文章。因?yàn)槌踔猩淖魑牟⒉恍枰獙懱珡?fù)雜的句子。僅僅是簡(jiǎn)單句子的結(jié)合，所以說(shuō)中學(xué)生的作文不叫真正意義上的作文，而是叫寫話。所以鑒于上述，我覺得英漢互譯寫句子是最好的寫作文的方法，把每句話成功的寫出來(lái)，再結(jié)合起來(lái)就是一篇好的作文了。機(jī)密★啟用前天津市2018年中考英語(yǔ)試題本試卷分為第1卷（選擇題）、第I卷（非選擇題）兩部分。第1卷為第1頁(yè)至第8頁(yè)，第I卷為第9頁(yè)至第12頁(yè)。試卷滿分120分?？荚嚂r(shí)間100分鐘。答卷前，請(qǐng)你務(wù)必將自己的姓名、考生號(hào)、考點(diǎn)校、考場(chǎng)號(hào)、座位號(hào)填寫在“答題卡”上，并在規(guī)定位置粘貼考試用條形碼。答題時(shí)，務(wù)必將答案涂寫在“答題卡”上，答案答在試卷上無(wú)效?？荚嚱Y(jié)束后，將本試卷和“答題卡”，并交回。祝你考試順利！第Ⅰ卷注意事項(xiàng)：1．每題選出答案后，用2B鉛筆把“答題卡”上對(duì)應(yīng)題目的答案標(biāo)號(hào)的信息點(diǎn)涂黑。如需改動(dòng)，用橡皮擦干浄后，再選涂其他答案標(biāo)號(hào)的信息點(diǎn)。2．本卷共五大題，共80分。一、聽力理解（本大題共20小題，每小題1分，共20分）A）在下列每小題內(nèi)，你將聽到一個(gè)或兩個(gè)句子并看到供選擇的A、B、C三幅圖畫。找出與你所聽句子內(nèi)容相匹配的圖畫。.B）下面你將聽到十組対話，每組對(duì)話都有一個(gè)問(wèn)題。根據(jù)對(duì)話內(nèi)容，從每組所給的A、B、C三個(gè)選項(xiàng)中找出能回答所提問(wèn)題的最佳選項(xiàng)5.WhatsportdoesLinglinglikebestA.SwimmingB.SkatingC.Playingtabletennis6.Wherearetheygoing?A.ToalibraryB.ToazooC.Toasupermarket7.Whosepensarethese?A.Daming’sB.Betty’sC.Tony’s8.Whoisthatman?A.BettysbrotherB.BellysdadC.Bettysuncle9.Whereisthewomanshometown?A.InthenorthofChinaB.InthesouthofChinaC.InthecastofChina10.HowoftendoesLilei'sgrandpagotoseetheBeijingOpera?A.OnceamonthB.TwiceamonthC.Threetimesamonth11.What’swrongwithJack?
