以下是新通小編為大家整理的雅思閱讀判斷題解析，供大家參考學(xué)習(xí)：
題目句子中的主謂賓結(jié)構(gòu)在原文中無(wú)法對(duì)應(yīng)，則答案判斷為Not Given。
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, and even radioactive fall-out from Chernobyl. 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.
分析：
第一步：確定題目中的定位詞。定位詞分別是時(shí)間表達(dá)式over the last 20 years，專有名詞Arctic和主語(yǔ)Industry。另外，考點(diǎn)詞是increased。
第二步：定位詞到原文中定位。文章原句是: 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, 我們發(fā)現(xiàn)在原文中的時(shí)間對(duì)應(yīng)詞和題目中的相同，而Arctic在原文中也沒(méi)有變化。而考點(diǎn)詞在原文中轉(zhuǎn)化成了increasing。原文的表述是 an increasing variety of toxic contaminants，說(shuō)明增加的是variety of toxic contaminants，而題目中的主語(yǔ)是Industry。而industry在文章中的表述是……heavy metals from industry。但這并不能判斷工業(yè)是否增長(zhǎng)。所以本題判斷為not given。
題目和原文都有比較，但是比較對(duì)象不同，則答案判斷為Not Given。
原文: Scientists have found that a smoked substance reaches the brain more quickly than one swallowed, snorted (such as cocaine powder) or even injected.
題目: Snorted substances reach the brain faster than injected substances.
分析：
題目和原文都有比較，比較的關(guān)鍵詞是reach the brain faster than，原文中有一個(gè)同義詞轉(zhuǎn)換結(jié)構(gòu)reaches the brain more quickly than。其中faster和more quickly構(gòu)成了同義詞轉(zhuǎn)換的用法。
題目中比較的兩方面是Snorted substances和injected substances。而原文的比較內(nèi)容是a smoked substance和swallowed, snorted (such as cocaine powder) or even injected。題目中的比較對(duì)象在原文中是并列關(guān)系，因此無(wú)法進(jìn)行比較，所以答案判斷為not given。
題目中表示現(xiàn)在狀況，而文章中表示將來(lái)的可能性，則答案判斷為Not Given，反之亦然。
原文: Nearly half the world’s population will experience critical water shortages by 2025, according to the United Nations (UN). Wars over access to water are a rising possibility in this century and the main conflicts in Africa during the next 25 years could be over this most precious of commodities, as countries fight for access to scarce resources.
題目: Some African countries are currently at war over water resources.
分析：
題目中定位詞African countries，war，water在原文中都可以定位相應(yīng)的詞匯。 但是題目中的關(guān)鍵詞是currently，而在文章中的表述是……during the next 25 years could be……�，F(xiàn)在和將來(lái)的兩種狀態(tài)無(wú)法進(jìn)行比較。所以答案判斷為not given。
原文中有表示極端的修飾詞如most, all, any等，而在文章中無(wú)法搜索到相關(guān)的同義表述，則答案判斷為Not Given。
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.
分析：
通過(guò)題目中的兩個(gè)專有名詞Canada和hydroelectric power定位。原文提到了Hydroelectric power in Canada is plentiful and provides 60% of their electrical requirements. 但是并沒(méi)有說(shuō)到most……in the world today。從上下文的關(guān)系來(lái)看文章中提到的most big hydroelectric projects being planned today are facing a great deal of hostility from environmental groups and local people也與題目的表述無(wú)關(guān)。。所以答案判斷為not given。
