雅思閱讀判斷題因果考點

 今天我們會分析判段題常出的另一個重要考點—因果關(guān)系,讓考生判斷一個句子中的因果關(guān)系是否和原文相符。因果關(guān)系類判斷題也有其獨特的做題方法，認真閱讀完這篇文章，再經(jīng)過集中練習(xí)，基本可以順利拿下因果關(guān)系類判斷題。

例題：

1.  Feeding increasing populations is possible due primarily to improved irrigation systems.

2.  Problems in Nordic countries were excluded because they are outside the European Economic Community.

3.  The success of the actual experiment was due to the high speed of the wind.

因果關(guān)系的標志很明確，就是因果關(guān)系連接詞，常出的因果關(guān)系連接詞有：

引導(dǎo)原因：because/ because of/ for/ due to/ thanks to/ owing to/ be attributed to/result from

引導(dǎo)結(jié)果：so / therefore/ thus/ as a consequence/ consequently

絕大多數(shù)情況下，因果關(guān)系類判斷題做題方法為：

拿結(jié)果定位，對原因進行判斷。

大家需要注意，雅思閱讀中因果關(guān)系類判斷題多考察原因的準確性，所以原因是我們需要去求證的內(nèi)容，切記不能當作定位。

方法操作：

題干：1.  Feeding increasing populations is possible due primarily to improved irrigation systems.

出題句：Food production has kept pace with soaring populations mainly because of the expansion of artificial irrigation systems that make possible the growth of 40 % of the world's food.

此題有明確的因果關(guān)系標志詞，所以屬于因果類判斷，我們定位應(yīng)該選擇的是本句的結(jié)果：Feeding increasing populations is possible，在文章中很快能定位到出題句，精讀出題句核對原因的準確性， due primarily to的同義轉(zhuǎn)換為 mainly because of， improved irrigation systems的同義轉(zhuǎn)換為 expansion of artificial irrigation systems，原因吻合，這道題選擇TRUE.

題干：2.  Problems in Nordic countries were excluded because they are outside the European Economic Community.

出題句：Those confined to particular geographical areas, such as countries bordering the Mediterranean or the Nordic countries therefore had to be discarded. However, this does not mean that in future they will be ignored.

此題也是典型的因果關(guān)系判斷題，還是按照我們的方法，定位結(jié)果，需要定位 Problems in Nordic countries were excluded，很快找到其同義轉(zhuǎn)換為Nordic countries therefore had to be discarded。而根據(jù)therefore我們得知原因在句子前半部分，原因為Those confined to particular geographical areas， 原因不吻合，所以我們選擇FALSE。

題干：3.  The success of the actual experiment was due to the high speed of the wind.

出題句：The wind was blowing at a gentle 16 to 20 kilometres an hour, little more than half what they thought would be needed. What they had failed to reckon with was what happened when the kite was opened. 'There was a huge initial force- five times larger than the steady state force,' Gharib says. This jerk meant that kites could lift huge weights, Gharib realised.

該題中，我們還是需要拿“實驗的成功”來做定位，核對成功是否是因為風(fēng)速大。根據(jù)結(jié)果定位找到出題句，通過精讀，我們從gentle得知這場實驗的風(fēng)速是柔和的，所以實驗的成功并不是因為大風(fēng)速，所以此題選擇FALSE。

今天的內(nèi)容我們分析到這里，最后還要啰嗦一句，熟能生巧，同學(xué)們課下一定要多加練習(xí)，祝大家考試順利～
