二看逻辑：
1.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。
48. B strength
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.
51. K starvation
2.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”。
47. F phenomenon
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。主要的如下。
递进：Moreover/furthermore/what’more/besides/in addition/even/also
转折：however/but/rather/instead
因果：therefore/consequently/accordingly/thus/hence
3.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。
52. J destructive (dead , damage)
三看习惯用法：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.
53. N worth 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。
e.g. The fire caused thousands of pounds' worth of damage.
