剛剛新航道雅思小編給大家分享了劍橋雅思4Test2閱讀passage3原文+譯文：玩耍是件嚴(yán)肅的事，本篇文章就是相應(yīng)的原文答案解析，下面就是關(guān)于劍橋雅思4Test2閱讀passage3答案解析。

  劍橋雅思4Test2閱讀passage3答案解析

  Question 27

  答案：H

  關(guān)鍵詞：unusual connection

  定位原文：H段最后1句“By allowing link-ups between brain areas that might not normally communicate with each other, play may enhance creativity.”

  解題思路：link-up等于connection，后面的play may enhance creativity證明這種不尋常的聯(lián)系是有好處的。

  Question 28

  答案：F

  關(guān)鍵詞：record/time

  定位原文：F段第2句“If you plot the amount of time...”

  解題思路：這個(gè)heading的意思是由記錄小動(dòng)物玩耍的時(shí)間而得到的見解，關(guān)鍵詞是時(shí)間，回到文章當(dāng)中尋找對(duì)應(yīng)詞時(shí)，只有這個(gè)段落提到了時(shí)間。plot一詞是用圖表記錄的意思，在這里就等同于record。

  雅思閱讀4Test2答案及解題思路指導(dǎo)Question 29

  答案：A

  關(guān)鍵詞：physical hazard

  定位原文：A段第4句之后“For a start, play can even cost animals their lives. Eighty per cent of deaths among juvenile fur seals…”

  解題思路：?jiǎn)栴}是問哪一段包含有對(duì)玩要帶來的危險(xiǎn)的描述。文章中只有在第一段中談到了玩要可能帶來的危險(xiǎn)，而且還舉出了小海狗的例子來說明這種危險(xiǎn)的存在。

  Question 30

  答案：H

  關(guān)鍵詞：mental/exercise/develop

  定位原文：H段前3句“Not only is more of the brain involved in play than was suspected, but it also seems to activate higher… and rules.”

  解題思路：mental activity是大腦活動(dòng)的意思，問題問的是在玩耍過程當(dāng)中，哪些大腦活動(dòng)得到了練習(xí)和發(fā)展。

  Question 31

  答案：I

  關(guān)鍵詞：effects/reduction

  定位原文：I段首句和2句“What might further experimentation… with their peers.”

  解題思路：?jiǎn)栴}問得是哪一段包含了這樣的內(nèi)容：減少玩耍機(jī)會(huì)可能對(duì)兒童造成的影響。在最后一段中，作者談到了被剝奪了玩耍機(jī)會(huì)的小老鼠大腦就發(fā)育的不好，并且用一個(gè)設(shè)問句表明了他對(duì)人類兒童的憂慮。而且一般來講，含有effect的段意都是對(duì)應(yīng)文章的最后一段。

  Question 32

  答案：B

  關(guān)鍵詞：class/animals

  定位原文：B段第4句“Playfulness, it seems, is common only among mammals...”

  解題思路：B段中提到了玩要在哺乳動(dòng)物中很普遍，而且在有些鳥類當(dāng)中也存在，即提到了各種各樣的動(dòng)物。一些同學(xué)會(huì)在E段當(dāng)中看到fifteen orders of mammals一詞，不過仔細(xì)讀下來，E段的主要意思是在講哺乳動(dòng)物中大腦大小和玩耍之間的關(guān)系，并不是說玩耍對(duì)哪種動(dòng)物重要。故答案選B。

  Question 33-35

  答案：ACF(IN EITHER ORDER)

  Question 33

  答案：A

  關(guān)鍵詞：rehearsal/adult

  定位原文：B段倒數(shù)第2句“A popular explanation of play has been that it helps juvenile develop the skills they will need to hunt, mate and socialize as adults.”

  解題思路：這段中提到了幫助青少年培養(yǎng)作為成年人需要的一些技能，所以A選項(xiàng)正確。

  Question 34

  答案：C

  關(guān)鍵詞：build up strength

  定位原文：B 段最后一句“Another has been that it allows young animals to get in shape for adult life...”

  解題思路：“使年輕的動(dòng)物保持體形”與C選項(xiàng)對(duì)應(yīng)。

  Question 35

  答案：F

  關(guān)鍵詞：organ growth

  定位原文：E段首句：“...reported that there is a strong positive link between brain size and playfulness…”

  解題思路：“在腦部大小與玩耍之間有正面的關(guān)聯(lián)”與F選項(xiàng)對(duì)應(yīng)。

  點(diǎn)擊獲取劍橋雅思4閱讀原文+參考譯文+答案解析

  Question 36

  答案：B

  關(guān)鍵詞：Robert Barton

  定位原文：E段倒數(shù)第2句和末句 “Robert Barton of Durham University …I concluded it's to do with learning，and with the importance of environmental data to...”

  解題思路：Barton認(rèn)為玩耍與學(xué)習(xí)有關(guān)，也與大腦發(fā)育過程中環(huán)境資料的重要性有關(guān)。Environmental data可以與physical surroundings對(duì)應(yīng)。

  Question 37

  答案：G

  關(guān)鍵詞：Marc Becoff

  定位原文：G 段第4句“Bekoff likens it to a behavioural kaleidoscope...”

  解題思路：Becoff將玩耍比喻為一個(gè)行為萬花筒，這句話也就是說在玩耍當(dāng)中動(dòng)物會(huì)做出各種各樣的舉動(dòng)，正好和G選項(xiàng)中的a wide range of相對(duì)應(yīng)。

  Question 38

  答案：E

  關(guān)鍵詞：John Byers

  定位原文：C段第2句“Byers points out that the benefits of increased exercise disappear rapidly after training stops, so...”

  解題思路：Byers認(rèn)為訓(xùn)練一結(jié)束，由增強(qiáng)訓(xùn)練所帶來的好處就跟著迅速消失了，無論什么種群的動(dòng)物，玩耍都傾向于在哺乳期的中期達(dá)到頂峰，然后則開始走了下坡路。這就與E答案觀點(diǎn)—致。

  Question 39

  答案：D

  關(guān)鍵詞：Sergio Pellis

  定位原文：E段第1句“...reported that there is a strong positive link between brain size and playfulness among mammals in general.”

  解題思路：Pellis認(rèn)為哺乳動(dòng)物的玩耍量與他們大腦的大小往往成正比。所以玩耍比較少的動(dòng)物腦子也比較小。

  Question 40

  答案：A

  關(guān)鍵詞：Stephen Siviy

  定位原文：H段第6句“Siviy studied how bouts of play affected the brain's levels of a particular chemical associated with..”

  解題思路：Siviy認(rèn)為玩耍能夠影響大腦中一種特殊化學(xué)物質(zhì)，這種物質(zhì)會(huì)刺激神經(jīng)細(xì)胞生長(zhǎng)。答案選A。
