真題演練
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 (信風(fēng)), 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 (潮濕的) 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
綜合解題
1. 辨析詞性
1) 遇到動(dòng)詞要進(jìn)行二次分類：確定時(shí)態(tài)，確定是第三人稱單數(shù)還是非第三人稱單數(shù);但應(yīng)注意動(dòng)詞+ed型的有兩種可能性，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。
3) 詞性一時(shí)無法確定的，暫時(shí)擱置，不必糾纏，影響全局。
4) 作出相應(yīng)的標(biāo)記。可直接用自己最清楚的符號(hào)清楚標(biāo)在每個(gè)詞前后。不清楚的都標(biāo)問號(hào)。
名詞：B F H K M(B的后綴-th，H、K、M的-tion都是名詞后綴)
謂語動(dòng)詞：A D O(A的-ate極可能是動(dòng)詞，D的-fy為動(dòng)詞后綴)
非謂語動(dòng)詞：L(-ing結(jié)尾)
形容詞：E G J(E的-cal、G的-able、J的-tive是形容詞后綴)
副詞：C和I(-ly加在形容詞后為副詞后綴)
注意：即使從沒見過，也想辦法看能否判斷其詞性，詞的性質(zhì)有時(shí)比詞義還重要。詞的性質(zhì)并不總是固定的，有些不認(rèn)識(shí)的或無法確定的，如N) worth(adj/n)，可先擱置，不要過度糾纏。
2. 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，中間是動(dòng)詞。根據(jù)一句(包括從句)有且只有一個(gè)謂語動(dòng)詞的原則，其它地方如無謂語動(dòng)詞，則需要謂語動(dòng)詞;反之則不需要謂語動(dòng)詞。
Nowadays, weather experts are able to forecast when an El Nino will (55) , but…(will后面必然是原形動(dòng)詞，一起構(gòu)成謂語)
Scientists (54) this to be the longest El Nino for 2,000 years.(此句后只有一個(gè)to be，是非謂語動(dòng)詞，故空格必為謂語動(dòng)詞;且空格前后均為名詞性，也基本確定它是動(dòng)詞。)
一個(gè)完整的句子之后再跟逗號(hào)，后面一般是非謂語動(dòng)詞短語。
The rainfall is increased across South America, (50) floods to Peru.(前面是一個(gè)完整的'句子，逗號(hào)后跟的，一般是非謂語動(dòng)詞短語。此題選項(xiàng)中非謂語動(dòng)詞只有一個(gè)，故直選之。)
2)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.
The hot, humid (潮濕的) 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.(前面是最高級(jí)的修飾語，自然是形容詞。)
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)
謂語動(dòng)詞前有名詞主語
This strange (47) happens every five to eight years.(happens是謂語動(dòng)詞，也可知前面為名詞短語，缺一個(gè)核心名詞。)
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 from the east to warm up by as much as 5 °C.(在介詞in的后面，當(dāng)為名詞無疑，此處整個(gè)短語來修飾lessen，當(dāng)為在某個(gè)方面減少。)
3. 句里句外，猜測(cè)詞義
1) 看搭配
主謂賓、主系表，與修飾詞直接的搭配關(guān)系決定著詞的意義，所以先看它被誰修飾，與誰形成什么關(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.(strange修飾47，也許看不出來是什么，再看47與happen形成主謂關(guān)系，能夠發(fā)生的是什么?最好的當(dāng)然是現(xiàn)象。)
2) 看邏輯
句內(nèi)(狀語從句、解釋、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.(此句有一個(gè)狀語從句，as表示的時(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。)
So 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”)
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的某個(gè)東西。前面講到過的核心概念就是El Nino, 無疑是一種天氣“現(xiàn)象”。)
表示可從前文找相應(yīng)線索的有兩類。與this一大類的還有：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。遞進(jìn)：moreover / furthermore / what’s more / besides / in addition / even / also。轉(zhuǎn)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.
段落開始部分，提出一個(gè)總的概括性的說法。往往在下文有分述。El Nino究竟帶來的是什么樣的天氣，后面一句就交代得十分清楚。
3) 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, 來表明價(jià)值某物的某東西。如：The fire caused thousands of pounds’ worth of damage.
