解題步驟
通讀全文，抓住中心(首段、首句原則);
閱讀選項，詞性分類(注意分析動詞時態);
全盤考慮，靈活選擇(根據所需詞性縮小範圍，每詞只能用一次);
復讀全文，覈查答案(快速復讀，用語感判斷是否通順準確)。
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), 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 (潮溼的) 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) 遇到動詞要進行二次分類：確定時態，確定是第三人稱單數還是非第三人稱單數;但應注意動詞+ed型的有兩種可能性，動詞或形容詞。遇到名詞要確定單數還是複數。
2) 不認識的單詞，看後綴。構詞法中，前綴表明意思，後綴表明詞性。
3) 詞性一時無法確定的，暫時擱置，不必糾纏，影響全局。
4) 作出相應的標記。可直接用自己最清楚的符號清楚標在每個詞前後。不清楚的都標問號。
名詞：B F H K M(B的後綴-th，H、K、M的-tion都是名詞後綴)
謂語動詞：A D O(A的-ate極可能是動詞，D的-fy爲動詞後綴)
非謂語動詞：L(-ing結尾)
形容詞：E G J(E的-cal、G的-able、J的-tive是形容詞後綴)
副詞：C和I(-ly加在形容詞後爲副詞後綴)
注意：即使從沒見過，也想辦法看能否判斷其詞性，詞的性質有時比詞義還重要。詞的'性質並不總是固定的，有些不認識的或無法確定的，如N) worth(adj/n)，可先擱置，不要過度糾纏。
2. 確定選項的選擇範圍
1)關於動詞的判斷
前後都是名詞短語，中間是動詞。根據一句(包括從句)有且只有一個謂語動詞的原則，其它地方如無謂語動詞，則需要謂語動詞;反之則不需要謂語動詞。
Nowadays, weather experts are able to forecast when an El Nino will (55) , but…(will後面必然是原形動詞，一起構成謂語)
Scientists (54) this to be the longest El Nino for 2,000 years.(此句後只有一個to be，是非謂語動詞，故空格必爲謂語動詞;且空格前後均爲名詞性，也基本確定它是動詞。)
一個完整的句子之後再跟逗號，後面一般是非謂語動詞短語。
The rainfall is increased across South America, (50) floods to Peru.(前面是一個完整的句子，逗號後跟的，一般是非謂語動詞短語。此題選項中非謂語動詞只有一個，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)後必有名詞。
This strange (47) happens every five to eight years.
The hot, humid (潮溼的) 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.(前面是最高級的修飾語，自然是形容詞。)
副詞修飾形容詞或動詞
…, 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, 當爲副詞)
謂語動詞前有名詞主語
This strange (47) happens every five to eight years.(happens是謂語動詞，也可知前面爲名詞短語，缺一個核心名詞。)
介詞後面必有名詞
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的後面，當爲名詞無疑，此處整個短語來修飾lessen，當爲在某個方面減少。)
3. 句裏句外，猜測詞義
1) 看搭配
主謂賓、主系表，與修飾詞直接的搭配關係決定着詞的意義，所以先看它被誰修飾，與誰形成什麼關係。看一種關係不行就看另一個，靈活處之。
This strange (47) happens every five to eight years.(strange修飾47，也許看不出來是什麼，再看47與happen形成主謂關係，能夠發生的是什麼?最好的當然是現象。)
2) 看邏輯
句內(狀語從句、解釋、並列等)
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.(此句有一個狀語從句，as表示的時間或因果關係，是重要的解題線索。風的什麼減少，溫度就上升，當然是風的速度或風力。)
So while some parts of the world prepare for heavy rains and floods, other parts
face drought, poor crops and (51).(空格與前面兩個名詞並列，意味着意思相近。與乾旱、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東西。前面講到過的核心概念就是El Nino, 無疑是一種天氣“現象”。)
表示可從前文找相應線索的有兩類。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係的句間連詞，或者叫連接副詞。遞進：moreover / furthermore / what’s more / besides / in addition / even / also。轉折：however / but / rather / instead。因果：therefore / consequently / accordingly / thus / hence。
後文
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究竟帶來的是什麼樣的天氣，後面一句就交代得十分清楚。
3) 看習慣用法、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這個詞的特殊用法。它本是一個形容詞，但可用…worth of sth, 來表明價值某物的某東西。如：The fire caused thousands of pounds’ worth of damage.
