新四级选择应灵活求解
二、灵活求解
将选项分类之后，就得从文章中来探求对应的线索了。选项与文章婚配的身分有两个，第一是词性，第二才是词义。所以在读文章时，要经由历程各种手腕来确定空格的词性与意义。
1.确定词性，确定在选项中的选择范围
1)关于动词的判定
l前后都是名词短语，中心是动词
l根据一句(包括从句)有且只要一个谓动的准绳，别的中央如无谓语动词，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背面肯定是底细动词，一同组成谓语)
Scientists 54 this to be the longest El Nino for 2,000 years.(此句后只要一个to be，长短谓语动词，故空格必为谓语动词；且空格前后均为名词性，也根基确定它是动词。)
l一个完整的句子之后再跟逗号，背面通俗长短谓语动词短语。
The rainfall is increased across South America, 50 floods to Peru. (背面是一个完整的句子，逗号后跟的，通俗长短谓语动词短语。此题选项中非谓语动词只要一个，故直选之。)
2)别的词的判定
l描述词或名词润色名词，限制词(the, this, that, a, my之类)后必著名词
This strange 47 happens every five to eight years. (这个/种特另外？，固然要一个名词了)
The hot, humid (潮湿的) air over the ocean causes severe 49 thunderstorms.(重要的？风暴，年夜概是描述词，也年夜概是名词)
El Nino usually lasts for about 18 months. The 1981-83 El Nino brought the most 52 weather in modern history.(背面是最后级的润色语，天然是描述词。)
l副词润色描述词或动词
…, but they are still not 56 sure what leads to it or what affects how strong it will be.(润色描述词sure,当为副词)
l谓语动词前著名词主语
This strange 47 happens every five to eight years.(happens是谓语动词，也可知背面为名词短语，缺一个焦点名词。)
l介词背面必著名词
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的背面，当为名词无疑，留意要搞清晰，in有多种意义，此处整个短语来润色lessen淘汰，当为在某个方面淘汰。)
二、句里句外，预测词义
一看搭配：主谓宾、主系表与润色
词直接的搭配干系决议着词的意义。所以先看它被谁润色，与谁组成主谓宾干系。看一种干系不可就看另一个，灵活处之。
This strange 47 happens every five to eight years.
Strange润色47，年夜概看不出来是什么，再看47与happen组成主谓干系，可以发作的是什么？最好的固然是现象。
二看逻辑：
1.句内(状语从句，注释，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默示的时候或因果干系，是重要的解题线索。风的什么淘汰，温度就下降，固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.
空格与背面两个名词并列，意味着意思相类。与干旱、收成欠好一家的，很随便选出starvation饥馑.
2.前文(指代等、句间连词)
This strange 47 happens every five to eight years.
This通知我们，此处是重提背面讲到过的某个东西。背面讲到过的焦点不雅观点便是El Nino,无疑是一种气候“现象”。
默示可夙昔文找响应线索的有两类。
与this一年夜类的另有：This/these/such; the same/similar; worse/better/more/less等。
另有便是默示逻辑干系的句间连词，大概叫连接副词。重要的如下。
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(总分)
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，提出一个总的归结综合性的说法。频频鄙人文有分述。El Nino毕竟带来的是什么样的气候，背面一句就交代得非常清晰。
