英語四級十五選十技巧（課堂PPT）

1、1Word Selection2 15選10是大英四級改革后閱讀的新題型，有些同學做這 題時會盲目地“試答案”，這不僅會使正確率下降，還會影響答題時間。其實，做這種題時還是有很多 規(guī)律可循的。一般將備一般將備選分類是最有效的方法，可以按詞性劃分為名選分類是最有效的方法，可以按詞性劃分為名詞、動詞、形容詞和副詞。詞、動詞、形容詞和副詞。同樣，平均到這些類別中的詞匯也減少到了3、4個，這樣通過上下 文判別空缺單詞的詞性來有的放矢地選擇答案，作對的幾率就會明顯上升。 3對于對于15選選10的題型，解題步驟有四步：的題型，解題步驟有四步：第一步：通讀全文， 特別是每個段落的首末句，迅速抓住文章的主題和

3、r/or/ist/ism形容詞后綴形容詞后綴：able/al/ant/ent/tive/sive/ous/less/ed/ing動詞后綴動詞后綴:ate/lize/ing/ed副詞后綴副詞后綴：ly/ward/wise5答題技巧一：確定空白處詞性v以下情況，空白處為動詞：1 n./pron. Vt. n./pron. 前有名后有名，中間謂動2 n./pron. Vi.前名后無名，謂動不及物3 n./pron. Vi. adv./prep.前名后介副，謂動不及物4 n./pron. link v./be adj.前名后形容，be動或系動5 to v.前有to，后原型注意：確定空白處為動詞，還需根

4、據(jù)上下文確定正確形式6以下情況，空白處為分詞：v過去分詞：has/have/had p.p（完成時態(tài)）be p.p（被動語態(tài)）p.p n.或 n. p.p（過去分詞做形容詞，表示被動或已發(fā)生）v現(xiàn)在分詞：be -ing（進行時態(tài)）-ing n.或n.-ing（現(xiàn)在分詞做形容詞，表示主動或正在進行）prep. ing（介詞賓語）7以下情況，空白處為名詞：（名詞通常做主語或動詞介詞賓語）a/the n. 前有冠詞n. V. 空白后為謂語動詞prep. n. 空白前為介詞，則空白處為名詞或動名詞（注意：根據(jù)空白處前的冠詞和上下文判斷所填名詞的單復數(shù)；根據(jù)空白處后的謂語動詞的形式判斷所填名詞的單復數(shù)）

5、8以下情況，空白處為形容詞：adj. n. n. adj. 空白前后是名詞adv. adj. 空白前是副詞link v.be adj. be動或系動后考慮形容詞做表語9以下情況，空白處為副詞：adv. v.或 v. adv.副詞修飾動詞，表示程度狀態(tài)adv. adj.副詞可修飾形容詞adv.從句，有些副詞做句子的狀語，表示轉(zhuǎn)折因果等邏輯關(guān)系10答題技巧二：確定考點需要積極意義還是消極意義，繼而縮小選擇范圍，節(jié)省大量時間Sample:The classroom (offers) opportunities for children to replace angry, violent behavi

6、ors with , peaceful ones.（根據(jù)語法判斷此處為形容詞，與peaceful有一樣具有積極意義，與前文的angry, violent詞義色彩相反，那么comprehensive, cooperative, entire應選擇cooperative)11答題技巧三：后一定是名詞或動名詞做賓語注意 to （介詞介詞&動詞不定式）to的短語接動名詞 :abandon oneself to（沉溺于）, adhere to（堅持）, stick to（堅持，信守）, cling to（堅持，忠于）, admit to（承認）, confess to（承認）, contribu

9、 executive,)extensive為正確答案， 13答題技巧五：充分利用詞庫中的近義詞或反義詞（若詞庫中出現(xiàn)一對近義或反義詞，其中一個必定是干擾項反義詞考查學生對文章語境色彩的辨析，只要辨析考點單詞是積極還是消極意義，就不難排除近義詞考查考生對詞匯搭配用法的掌握，需要學生牢記近義詞的各種用法及搭配。）Sample: A) gravely B) respect C) limited D) specialize E) seriously F) promoting G) involves H) relieved I) significant J) magnificent K) range L

10、) issues M) result N) determining O) complicatedToday, we take pain_.（此處應用副詞做狀語，考查近義詞辨析Take sth. Seriously為固定搭配）14答題技巧六：注意一詞多性： 詞庫中的詞有的既是名詞又是動詞，有些分詞也可以充當形容詞，確定空白處所需單詞詞性后要全面考慮詞庫中的單詞詞性，不能遺漏(respect, result, range)15 As an Alaskan fisherman.
