是非無判斷題是雅思閱讀考試中的一類經(jīng)典題型,掌握此類題型的考察形式是解決這種題目的關(guān)鍵。在這類題目中,考察的難度也是不一樣的。除了經(jīng)典的大家十分熟悉的同義轉(zhuǎn)換套路以外,分析認(rèn)為此類題的最大難點(diǎn)就在于題目和原文相應(yīng)位置的同義轉(zhuǎn)換十分隱含,需要通過對原文的歸納和推理才能確定。如果按照原文意思推斷過多,就可能造成原本應(yīng)該是NG的答案卻做成True,諸如此類的題目判斷的程度是十分難把握的。

TRUE類題目的難點(diǎn)

1) 題目是原文的同義轉(zhuǎn)換

在同義轉(zhuǎn)換的考察形式中,普通的同義詞考察是最簡單的,例如increase和go up/rise等進(jìn)行替換。而在雅思閱讀中,同義的概念更常出現(xiàn)于句式上??聪旅娴睦樱?/p>

原文:Few rabbits in the wildness are more than five years old.

題目:Most rabbits are less than five years old.

這兩個(gè)句子都是用的比較句型,看起來比較簡單,但也運(yùn)用了邏輯推理,屬于比較難把握的同義替換。

再比如,

原文:Computers are gaining in popularity, despite their cost.

題目:Computers are more popular than they used to be.

這兩個(gè)句子都在表達(dá)電腦越來越受到人們的歡迎,而句式上,一個(gè)用了進(jìn)行時(shí)態(tài),另一個(gè)卻用了現(xiàn)在與過去的比較。

2) 題目是對原文的合理歸納

原文:It has been proved that a rapid response leads to a great likelihood of arrest only if it is 1-2 minutes after a call is received by police. When the response time increases to 3-4 minutes, the likelihood of an arrest is substantially reduced.

題目:A delay of 1-2 minutes in response may have substantial influence on whether or not a suspected criminal is caught.

題目中的have substantial influence就是對原文中細(xì)節(jié)解釋的歸納,這個(gè)題目很容易被學(xué)生看成是NG,這是比較難的考察點(diǎn)。

FALSE類題目的難點(diǎn)

1) 題目與原文意思矛盾

這樣的題目通常是比較明顯,也比較好把握的,只需找到對應(yīng)位置,根據(jù)原文可以很肯定地指出兩者的矛盾之處。

原文:In biological terms, a species is said to be extinct when its last individual dies.

題目:Biologically, a species is said to be extinct when only one individual exist.
