雅思閱讀是非題Y/N/NG選擇情況

在上篇中給大家講了雅思閱讀是非題的解題重點(diǎn)，下面我給大家講一下什么情況下是yes, 什么情況下是no 還有什么情況下是NG?

1. Yes

第一種情況：題目是根據(jù)原文同義表達(dá)：通常是同義詞之間的替換或者是同義結(jié)構(gòu)。

舉例：原文：According to the survey of 2012，men are taller than women.

題目：The survey of 2012 finds that women are smaller than men.

定位詞是年代2012， 考點(diǎn)詞是taller (同義結(jié)構(gòu))

原文：Frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise.

題目：Biologists are unable to explain why the frogs are dying.

定位詞：biologists 學(xué)科類的專有名詞，生物學(xué)家。 考點(diǎn)詞： unable (同義詞)

(把自己想象成考官，你會怎么考察，是able，還是 unable呢)

第二種情況：題目是根據(jù)原文中的話來推斷出來。

舉例： 原文：On 13 July 1907, Baekeland took out his famous patent describing his Modern-day plastic preparation, the essential features of which are still in use today.

題目: Modern-day plastic preparation is based on the same principles as that patented in 1907.

定位詞：年代1907， 考點(diǎn)詞： same (句子意思推斷答案)

2. False

第一種情況： 題目與原文的意思相反： 通常是反義詞， 否定詞no never not+同義詞，或者是反義結(jié)構(gòu)

舉例： 原文：Eating hamburgers is beneficial to peoples’ health.

題目：Eating hamburgers is bad for peoples’ health.

定位詞：Eating hamburgers 考點(diǎn)詞：形容詞bad

(把自己想象成考官，你會怎么考察，是bad，還是 good呢)

原文：Data showing the scale of the nickel sulphide problem is almost impossible to find.

題目：There is plenty of documented evidence available about the incidence of nickel sulphide failure.

定位詞： nickel sulphide 考點(diǎn)詞： plenty of 介詞短語做形容詞

(把自己想象成考官，你會怎么考察，是多，還是 少呢)

第二種情況：原文中是幾個條件得出一個結(jié)論，條件以并列的方式出現(xiàn)，常用both..and.., and, or 或者also等， 題目卻出現(xiàn)must 或者only，表示只有這個條件就可以得到結(jié)論。

舉例： 原文：Since the Olympics began, 36 out of 58 gold medals have been won by the athletes from China and USA.

題目：Only the competitors in China have won the gold medals in the Olympics.

定位詞： Olympics 考點(diǎn)詞： only

第三種情況：原文是某種理論或者是感覺，比如theory， feel等，而題目是事實或已經(jīng)被證明，常有fact 或者prove等詞。

舉例： 原文: The professor feels/guesses that H7N9 can transmit from people to people.

題目: The professor proves that H7N9 can transmit among the people.

定位詞： H7N9 考點(diǎn)詞： proves

第四種情況: 原文和題目使用了表示不同頻率或者范圍的詞匯。比如: 原文中用most，題目中用all或者few， 原文中用sometimes，題目中用often之類的詞， 原文中用possible而題目是impossible等。

舉例： 原文： Most people in the class are from Shanghai.

題目： All the people in the class are from Shanghai.

定位詞： Shanghai 考點(diǎn)詞： All

第五種情況：原文中包含條件狀語if/unless/Provided that…(假如) 或者是in… 和 with…介詞短語表示條件狀語，題目卻去掉了這些表示條件狀語的部分。

原文：The Internet is a hazardous tool in the hands of small children.

題目: The Internet is a dangerous instrument.

定位詞： Internet 考點(diǎn)詞： dangerous

原文： Lily can ride the bike with the help of her mother.

題目： Lily can ride the bicycle.

定位詞：Lily 考點(diǎn)詞： can

3. Not Given

第一種情況：題目在原文中找不到依據(jù)。 切記不能光憑自己的知識理解來判斷，即使出現(xiàn)題目中說“地球是方的”.

第二種情況: 題目的范圍比原文的范圍小。(如果反過來，就是T)

舉例：原文：Tea is good for peoples’ health.

題目：People can get benefits from Green Tea.

第三種情況：題目中有比較結(jié)構(gòu)，原文中無比較結(jié)構(gòu)。

舉例： 原文: And the future? It is anticipated that, in the years to come, leisure facilities spending will account for between a third and a half of all household spending. Whilst it is difficult to give exact figures, the leisure industry will certainly experience a long period of sustained growth.

題目: In future, people will pay less for the leisure facilities they use than they do today.

定位詞： leisure facilities 考點(diǎn)詞: less

第四種情況： 題目中有表示趨勢的詞或詞組，而原文卻無法找到相關(guān)的表達(dá)。

舉例：原文：The future, we are told, is likely to be different. Detailed surveys of social and economic trends in the European Community show that Europe’s population is falling and getting older. The birth rate in the Community is now only three-quarters of the level needed to ensure replacement of the existing population. By the year 2020, it is predicted that more than one in four Europeans will be aged 60 or more and barely one in five will be under 20. In a five-year period between 1983 and 1988 the Community’s female workforce grew by almost six million. As a result, 51% of all women aged 14 to 64 are now economically active in the labor market compared with 78% of men.

題目：The rise in the female workforce in the European Community is a positive trend.

定位詞：European Community female workforce(專有名詞) 考點(diǎn)詞：positive

這道題引出：如果原文沒有提到，也只能是NG。或者，題目中表示現(xiàn)在情況，而原文表示將來或者過去，也是NG，反之亦然。

第五種情況：主題動作發(fā)生的時間段不一樣，導(dǎo)致主題信息無法判斷。

舉例：

原文：Since the early years of the twentieth century, when the International Athletic Federation began keeping records, there has been a steady improvement in how fast athletes run, how high they jump…

題目: There was little improvement in athletic performance before the twentieth century.

定位詞：年代twentieth century 考點(diǎn)詞: little, before

第5種情況：題目中句子的主語或賓語和原文中的主語和賓語進(jìn)行了“偷天換日”， 因此無法判斷，為NG。

舉例：

原文：In the last 20 years, scientists have detected an increasing variety of toxic contaminants in the North, including pesticides from agriculture, chemicals and heavy metals from industry. These are substances that have invaded ecosystems virtually worldwide, but they are especially worrisome in the Arctic.

題目：Industry in the Arctic has increased over the last 20 years.

定位詞：Arctic, 20 years 考點(diǎn)詞：increased

黃金法則1：題目中若出現(xiàn)must, only, all，most及always等極端絕對化的詞語，答案是80%是F， 20%是NG。

給大家舉個例子：

原文：Hydroelectric power is at present the earth’s chief renewable electricity source, generating 6% of global energy and about 15% of worldwide electricity. Hydroelectric power in Canada is plentiful and provides 60% of their electrical requirements. Usually regarded as an inexpensive and clean source of electricity, most big hydroelectric projects being planned today are facing a great deal of hostility from environmental groups and local people.

題目：Canada uses the most hydroelectric power in the world today.

定位詞：Canada ，hydroelectric power 考點(diǎn)詞：most

黃金法則2：連續(xù)3題答案出現(xiàn)一樣的答案的情況很少，連續(xù)4題答案一樣的不可能。

趨向分析法：題目中的考點(diǎn)詞和原文的意思風(fēng)格是否一致。比如說題目是上升，原文中是下降。

類比分析法：把題目中復(fù)雜的比較場景，遷移到自己用簡單的且便于理解的場景中替換，然后再判斷正確與否。

F與NG的最大區(qū)別是F是題目和原文的意思相反，NG是題目和原文的意思無關(guān)，或者無法判斷正確與否，有可能成立，也有可能不成立。
