1、第六講完形填空詞匯填空篇【考點(diǎn)說(shuō)明】完形填空除了傳統(tǒng)四選一的形式之外，也可能會(huì)出現(xiàn)一些變化，如將空缺所需答案放在一起，并給出 多余幾個(gè)選擇，共同組成一個(gè)詞庫(kù)，而考生則根據(jù)文章意思以及空缺上下文語(yǔ)境進(jìn)行選擇填詞，并根據(jù)需要進(jìn)行詞形的變換，英文名稱為Bank Cloze,類似于大學(xué)英語(yǔ)四級(jí)考試中的15選10題型。北約聯(lián)盟2011年和2012年自招考試英語(yǔ)皆出現(xiàn)了15選10題型。除此之外，2011北約自招英語(yǔ)考試還出現(xiàn)了首字母完形填空題型。盡管完形填空考察形式多樣，但萬(wàn)變不離其宗，只要掌握了完形填空考查的重點(diǎn)和答題技巧，一切問(wèn)題皆可迎刃而解?！绢}型特點(diǎn)分析】1 . 15 選 10:方框給出供選擇的1

3、但應(yīng)注意動(dòng)詞 的有兩種可能性，動(dòng)詞或形容詞；遇到名詞要確定單數(shù)還是復(fù)數(shù)。2 .不認(rèn)識(shí)的單詞，看后綴。構(gòu)詞法中，前綴表明意思，后綴表明詞性。所以看一個(gè)詞的后綴，往往能 大致分出詞性。3 .詞性一時(shí)無(wú)法確定的，暫時(shí)擱置，不必糾纏，影響全局。?以下情況，空白處為動(dòng)詞：1. n./pron.vt_ n./pron.2. n./pron.vi.3. n./pron.vi. adv./prep.4. n./pron.link v./be adj.5. to v4 .作出相應(yīng)的標(biāo)記?？芍苯佑米约鹤钋宄姆?hào)清楚標(biāo)在每個(gè)詞前后，不清楚的都標(biāo)問(wèn)號(hào)。前有名詞后有名詞，中間謂語(yǔ)動(dòng)詞 前有名詞后無(wú)名詞，謂語(yǔ)動(dòng)詞不及物

4、 前有名詞后有介詞副詞，謂語(yǔ)動(dòng)詞不及物 前有名詞后有形容詞，be動(dòng)詞或系動(dòng)詞 前有不定式to,后動(dòng)詞原形 注意：確定空白處為動(dòng)詞，還需根據(jù)上下文確定正確形式 以下情況，空白處為分詞：?過(guò)去分詞：1. has/have/had p.p （完成時(shí)態(tài)）2. be p2 （被動(dòng)語(yǔ)態(tài)）3. 吐 n.或n. p正（過(guò)去分詞做形容詞，表示被動(dòng)或已發(fā)生）?現(xiàn)在分詞：1. be -ing （進(jìn)行時(shí)態(tài)）2. -ing n.或n.-ing （現(xiàn)在分詞做形容詞，表示主動(dòng)或正在進(jìn)行）3. prep.

6、le:The classroom offers opportunities for children to replace angry, violent behaviors with , peaceful ones.【解析】根據(jù)語(yǔ)法判斷此處為形容詞，與peaceful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(yīng)選擇 cooperativeo答題技巧三：介詞后一定是名詞或動(dòng)名詞做賓語(yǔ).注意：to （介詞&動(dòng)詞不定式）to的短語(yǔ)接動(dòng)名詞：abandon oneself to （沉溺于）,

7、adhere to （堅(jiān)持）,stick to （堅(jiān)持，信守） ,cling to （堅(jiān)持，/忠于）,admit to （承認(rèn)），confess to （承認(rèn)），contribute to （做貢獻(xiàn)），feel up to （感覺(jué)能勝任），get down to （開(kāi)始著手做）,give one ' s mind，專心）,give way to （讓步）,yield to （屈服），lead to （導(dǎo)致）,look forward to （渴望），object to （反對(duì)），take to （開(kāi)始從事，喜歡），turn to （求助），succumb to （屈服），see to

9、arket for manyproducts.（scale, potential, gap, extreme, purchase, situation）【解析】作some of these jobs的同位語(yǔ)，以輔音開(kāi)頭的名詞。這里的situation意思是：（正職業(yè)，職位，工作。例：In August he was appointed to the situation of secretary. 在八月份,他被指定擔(dān)任秘書(shū)。答題技巧五：充分利用詞庫(kù)中的近義詞或反義詞（注意：若詞庫(kù)中出現(xiàn)一對(duì)近義或反義詞，其中一個(gè)必定是干擾項(xiàng)。反義詞考查學(xué)生對(duì)文章語(yǔ)境色彩的辨 析，只需要辨析考點(diǎn)單詞是積極還是消極

The hot, humid air over the ocean causes severe 49 thunderstorms. The rainfall is increased across South America, 50 floods to Peru. In the West Pacific

15、, there are droughts affecting Australia and Indonesia. So while some parts of the world prepare for heavy rains and floods, other parts face drought, poor crops and 51.EI Nino usually lasts for about 18 months. The 1982-83 EI Nino brought the most 52 weather in modern history. Its effect was worldw

Scientists 54 this to be the longest EI Nino for 2,000 years.Nowadays, weather experts are able to forecast when an EI Nino will 55 , but they are still not 56 sure

17、 what leads to it or what affects how strong it will be.【解析】辨析詞性1 .把十五個(gè)選項(xiàng)按詞性分別歸入名詞、動(dòng)詞、形容詞、副詞等類別。名詞：B,F,H,K,M （B的后綴th, H、K、M的tion都是名詞后綴）1） 謂語(yǔ)動(dòng)詞：A,D,O （A的-ate極可能是動(dòng)詞，D的-fy為動(dòng)詞后綴）2） 非謂語(yǔ)動(dòng)詞：L （-ing結(jié)尾）3） 形容詞：E, G, J （E的-cal, G的able, J的tive是形容詞后綴）4） 副詞：C和I （ly加在形容詞后為副詞后綴）注意：即使從沒(méi)見(jiàn)過(guò)，也想辦法看能否判斷其詞性，詞性有時(shí)比詞義還重要。詞性并

18、不總是固定的, 有些不認(rèn)識(shí)的或無(wú)法確定的，如 N） worth （adj./n.）,可先擱置，不要過(guò)度糾纏。綜合解題將選項(xiàng)分類之后，就得從文章中來(lái)尋找對(duì)應(yīng)的線索了。選項(xiàng)與文章匹配的因素有兩個(gè)，第一是詞性，第二是詞義。所以在讀文章時(shí)，要通過(guò)各種手段來(lái)確定空格的詞性與意義。（一）確定詞性，確定選項(xiàng)的選擇范圍1）關(guān)于動(dòng)詞的判斷?前后都是名詞短語(yǔ)，中間是動(dòng)詞。根據(jù)一句（包括從句）有且只有一個(gè)謂語(yǔ)動(dòng)詞的原則，其它地方如無(wú)謂語(yǔ)動(dòng)詞，則需要謂語(yǔ)動(dòng)詞； 反之則不需要謂語(yǔ)動(dòng)詞。Nowadays, weather experts are able to forecast when an El Nino will

19、55 , but. （will 后面必然是原形動(dòng)詞， 一起構(gòu)成謂語(yǔ)）55. O strikeScientists 54 this to be the longest El Nino for 2,000 years.（此句后只有一個(gè) to be,是非謂語(yǔ)動(dòng)詞， 故空格必為謂語(yǔ)動(dòng)詞；且空格前后均為名詞性，也基本確定它是動(dòng)詞。）54. A estimate?一個(gè)完整的句子之后再跟逗號(hào)，后面一般是非謂語(yǔ)動(dòng)詞短語(yǔ)。The rainfall is increased across South America, 50 floods to Peru.（前面是個(gè)完整的句子，逗號(hào) 后跟的，一般是非謂語(yǔ)動(dòng)詞短語(yǔ)。此

20、題選項(xiàng)中非謂語(yǔ)動(dòng)詞只有一個(gè)。）50. L bringing2）其它詞的判斷?形容詞或名詞修飾名詞，限定詞（ the, this, that, a, my之類）后必有名詞This strange 47 happens every five to eight years.（這個(gè)/種奇怪的？，需要一個(gè)名詞）47. FphenomenonThe hot, humid air over the ocean causes severe _49thunderstorms.（嚴(yán)重的？風(fēng)暴， 可能是形容詞， 也可能是名詞）49. E tropicalEl Nino usually lasts for about

21、 18 months. The 1981-83 El Nino brought the most _52 weather in modern history.（前面是最高級(jí)的修飾語(yǔ)，自然是形容詞。）52. J destructive副詞修飾形容詞或動(dòng)詞，but they are still not 56 sure what leads to it or what affects how strong it will be.（修飾形容詞 sure,當(dāng)為副詞） 56. I completely謂語(yǔ)動(dòng)詞前有名詞主語(yǔ)This strange 47- happens every five to eigh

22、t years. （happens是謂語(yǔ)動(dòng)詞，也可知前面為名詞短語(yǔ)，缺一個(gè)核心名詞。）47 F phenomenon介詞后面必有名詞As the trade winds lessen in 48, the ocean temperatures rise, causing the Peru current flowing in fromthe east to warm up by as much as 5 C.（在介詞in的后面，當(dāng)為名詞無(wú)疑，此處整個(gè)短語(yǔ)來(lái)修飾lessenM少， 當(dāng)為在某個(gè)方面減少。）48. B strength（二）句里句外，猜測(cè)詞義一看搭配：主謂賓、主系表與修飾詞直接的搭配

23、關(guān)系決定著詞的意義。所以先看它被什么修飾，與什么形成主謂 賓關(guān)系。看一種關(guān)系不行就看另一個(gè)，靈活處之。This strange 47 happens every five to eight years.（strangef啰飾47,也許看不出來(lái)是什么，再看47與happen成主謂關(guān)系，能夠發(fā)生的是什么？最好的當(dāng)然是現(xiàn)象。） 47. F phenomenon二看邏輯：1.句內(nèi)（狀語(yǔ)從句，解釋，并列等）As the trade winds lessen in 48, the ocean temperatures rise, causing the Peru current flowing in fr

24、omthe east to warm up by as much as 5 C. °（此句有一個(gè)狀語(yǔ)從句，asa示的時(shí)間或因果關(guān)系，是重要的解題線索。風(fēng)的什么減少，溫度就上升，當(dāng)然是風(fēng)的速度或風(fēng)力。）48. B strengthSo while some parts of the world prepare for heavy rains and floods, other parts face drought, poor crops and 51（空格與前面兩個(gè)名詞并列，意味著意思相近。與干旱、收成不好一致的，很容易選出starvation饑荒。）51 . K starvation

25、52 前文（指代等、句間連詞）This strange 47 happens every five to eight years.（This告訴我們，此處是重提前面講到過(guò)的某個(gè)事物。前面講到過(guò)的核心概念就是曰Nino,無(wú)疑是一種天氣 現(xiàn)象”。）47. F phenomenon表示可從前文找相應(yīng)線索的有兩類。與this大類的還有：this/these/such; the same/similar; worse/better/more/less 等。還有就是表示邏輯關(guān)系的句間連詞，或者叫連接副詞。主要的如下：遞進(jìn)： Moreover/furthermore/ what s more /beside

26、s/in addition/even/also轉(zhuǎn)折：however/but/rather/instead因果：therefore/consequently/accordingly/thus/hence53 后文El Nino usually lasts for about 18 months. The 1981-83 El Nino brought the most 52 weather in modern history. Its effect was worldwide and it left more than 2,000 people dead and caused over eigh

27、t billion pounds 53 of damage.段落開(kāi)始部分，提出一個(gè)總的概括性的說(shuō)法。往往在下文有分述。曰Nino究竟帶來(lái)的是什么樣的天氣，后面一句就交代得十分清楚。52. J destructive （dead , damage）三看習(xí)慣用法：固定搭配Its effect was worldwide and it left more than 2,000 people dead and caused over eight billion pounds 53 of damage.（此處考的是worth這個(gè)詞的特殊用法。它本是一個(gè)形容詞，但可用worth of sth .,來(lái)表明價(jià)

28、值某物的某東西。）53. N worthe.g. The fire caused thousands of pounds' worth of damage.三、帶項(xiàng)檢查帶入已選答案，重新通讀文章以核對(duì)其是否邏輯語(yǔ)意正確。invest, justify, activity, basically, run, inside, opportunity, interest, generally, offer, design, urban, translate, theme, lead, focus, conduct, build, entertainment, baseThe Expo 2010
