　　真题演练

　　EI Nino is the name given to the mysterious and often unpredictable change in

　　the climate of the world. This strange (47) happens every five to eight years. It starts in the pacific Ocean and is thought to be caused by a failure in the trade winds (信风), which affects the ocean currents driven by these winds. As the trade winds

　　lessen in (48), the ocean temperatures rise, causing the Peru current flowing in

　　from the east to warm up by as much as 5℃ (degrees centigrade).

　　The warning of the ocean has far-reaching effects. The hot, humid (潮湿的) air

　　over the ocean causes severe (49) thunderstorms. The rainfall is increased across

　　South America, (50) floods to Peru. In the West Pacific, 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 worldwide and it left more than 2,000 people dead and caused over eight billion pounds (53) of damage. The 1990 EI

　　Nino lasted until June 1995. 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 what leads to it or what affects how strong it will be.

　　A) estimate

　　B) strength

　　C) deliberately

　　D) notify

　　E) tropical

　　F) phenomenon

　　G) stable

　　H) attraction

　　I) completely

　　J) destructive

　　K) starvation

　　L) bringing

　　M) exhaustion

　　N) worth

　　O) strike

　　综合解题

　　1. 辨析词性

　　1) 遇到动词要进行二次分类：确定时态，确定是第三人称单数还是非第三人称单数;但应注意动词+ed型的有两种可能性，动词或形容词。遇到名词要确定单数还是复数。

　　2) 不认识的单词，看后缀。构词法中，前缀表明意思，后缀表明词性。

　　3) 词性一时无法确定的，暂时搁置，不必纠缠，影响全局。

　　4) 作出相应的标记。可直接用自己最清楚的符号清楚标在每个词前后。不清楚的都标问号。

　　名词：B F H K M(B的后缀-th，H、K、M的-tion都是名词后缀)

　　谓语动词：A D O(A的-ate极可能是动词，D的-fy为动词后缀)

　　非谓语动词：L(-ing结尾)

　　形容词：E G J(E的-cal、G的-able、J的-tive是形容词后缀)

　　副词：C和I(-ly加在形容词后为副词后缀)

　　注意：即使从没见过，也想办法看能否判断其词性，词的性质有时比词义还重要。词的性质并不总是固定的，有些不认识的或无法确定的，如N) worth(adj/n)，可先搁置，不要过度纠缠。

　　2. 确定选项的选择范围

　　1)关于动词的判断

　　前后都是名词短语，中间是动词。根据一句(包括从句)有且只有一个谓语动词的原则，其它地方如无谓语动词，则需要谓语动词;反之则不需要谓语动词。

　　Nowadays, weather experts are able to forecast when an El Nino will (55) , but…(will后面必然是原形动词，一起构成谓语)

　　Scientists (54) this to be the longest El Nino for 2,000 years.(此句后只有一个to be，是非谓语动词，故空格必为谓语动词;且空格前后均为名词性，也基本确定它是动词。)

　　一个完整的句子之后再跟逗号，后面一般是非谓语动词短语。

　　The rainfall is increased across South America, (50) floods to Peru.(前面是一个完整的'句子，逗号后跟的，一般是非谓语动词短语。此题选项中非谓语动词只有一个，故直选之。)

　　2)其它词的判断

　　形容词或名词修饰名词，限定词(the, this, that, a, my之类)后必有名词。

　　This strange (47) happens every five to eight years.

　　The hot, humid (潮湿的) air over the ocean causes severe (49) thunderstorms.

　　El Nino usually lasts for about 18 months. The 1981-83 El Nino brought the most (52) weather in modern history.(前面是最高级的修饰语，自然是形容词。)

　　副词修饰形容词或动词

　　…, but they are still not (56) sure what leads to it or what affects how strong it will be.(修饰形容词sure, 当为副词)

　　谓语动词前有名词主语

　　This strange (47) happens every five to eight years.(happens是谓语动词，也可知前面为名词短语，缺一个核心名词。)

　　介词后面必有名词

　　As the trade winds lessen in (48) , the ocean temperatures rise, causing the Peru

　　current flowing in from the east to warm up by as much as 5 °C.(在介词in的后面，当为名词无疑，此处整个短语来修饰lessen，当为在某个方面减少。)

　　3. 句里句外，猜测词义

　　1) 看搭配

　　主谓宾、主系表，与修饰词直接的搭配关系决定着词的意义，所以先看它被谁修饰，与谁形成什么关系。看一种关系不行就看另一个，灵活处之。

　　This strange (47) happens every five to eight years.(strange修饰47，也许看不出来是什么，再看47与happen形成主谓关系，能够发生的是什么?最好的当然是现象。)

　　2) 看逻辑

　　句内(状语从句、解释、并列等)

　　As the trade winds lessen in (48), the ocean temperatures rise, causing the Peru

　　current flowing in from the east to warm up by as much as 5 °C.(此句有一个状语从句，as表示的时间或因果关系，是重要的解题线索。风的什么减少，温度就上升，当然是风的速度或风力。)

　　So while some parts of the world prepare for heavy rains and floods, other parts

　　face drought, poor crops and (51).(空格与前面两个名词并列，意味着意思相近。与干旱、收成不好一致的，很容易选出starvation“饥荒”)

　　前文(指代等、句间连词)

　　This strange (47) happens every five to eight years.(This告诉我们，此处是重提前面讲到过的某个东西。前面讲到过的核心概念就是El Nino, 无疑是一种天气“现象”。)

　　表示可从前文找相应线索的有两类。与this一大类的还有：this / these / such; the same / similar; worse / better / more / less等。

　　还有就是表示逻辑关系的句间连词，或者叫连接副词。递进：moreover / furthermore / what’s more / besides / in addition / even / also。转折：however / but / rather / instead。因果：therefore / consequently / accordingly / thus / hence。

　　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 eight billion pounds (53) of damage.

　　段落开始部分，提出一个总的概括性的说法。往往在下文有分述。El Nino究竟带来的是什么样的天气，后面一句就交代得十分清楚。

　　3) 看习惯用法、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.

　　此处考的是worth这个词的特殊用法。它本是一个形容词，但可用…worth of sth, 来表明价值某物的某东西。如：The fire caused thousands of pounds’ worth of damage.
