2016年英語四級閱讀備考：選詞填空解題方法

綜合解題

將選項分類之后，就得從文章中來尋找對應的線索了。選項與文章匹配的因素有兩個，第一是詞性，第二是詞義。所以在讀文章時，要通過各種手段來確定空格的詞性與意義。

(一)確定詞性，確定選項的選擇范圍

1)關于動詞的判斷

前后都是名詞短語，中間是動詞 。

根據(jù)一句(包括從句)有且只有一個謂動的原則，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后面必然是原形動詞，一起構成謂語)

55. O strike

Scientists 54 this to be the longest El Nino for 2,000 years.

(此句后只有一個to be，是非謂語動詞，故空格必為謂語動詞;且空格前后均為名詞性，也基本確定它是動詞。)

54. A estimate

一個完整的句子之后再跟逗號，后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，逗號后跟的，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。)

50. L bringing

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.

47. F phenomenon

The hot, humid (潮濕的) air over the ocean causes severe 49 thunderstorms.

49. E tropical

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。)

52. J destructive

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, 當為副詞)

56. I completely

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，也可知前面為名詞短語，缺一個核心名詞。)

47. F phenomenon

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，當為名詞無疑，此處整個短語來修飾lessen減少，當為在某個方面減少。)

48. B strength
