劍橋雅思11test4passage1答案及解析

第1題答案是：FALSE

對(duì)應(yīng)原文：第1段：Any differences between them–one twin having younger looking skin,for example–must be due to environmental factors

答案解析：根據(jù)skin定位到第1段的最后。原文中明確提到，同卵雙胞胎的皮膚差異一定是由環(huán)境因素造成的。題干中的may be genetic causes與原文矛盾，因此確定答案為FALSE。

第2題答案是：NOT GIVEN

對(duì)應(yīng)原文：第2段：If identical twins are more similar to each other with respect to an ailment than fraternal twins are,then vulnerability to the disease must be rooted at least in part in heredity.

答案解析：原文中只是對(duì)同卵雙胞胎和異卵雙胞胎進(jìn)行了對(duì)比，完全沒有提到非雙胞胎。題干屬于無中生有，因此判斷答案為NOT GIVEN。

第3題答案是：NOT GIVEN

對(duì)應(yīng)原文：第4段：Over two decades 137 sets of twins eventually visited Thomas Bouchard’s lab in what became known as the Minnesota Study of Twins Reared Apart.

答案解析：原文中確實(shí)提到，Bouchard對(duì)出生之后分離的雙胞胎進(jìn)行研究，但卻并沒有說明他采用什么方式來招募這些雙胞胎。題干中的advertised in newspapers屬于無中生有，由此判斷答案為NOT GIVEN。

第4題答案是：TRUE

對(duì)應(yīng)原文：第7段：Epigenetic processes are chemical reactions tied to neither nature nor nurture

答案解析：雖然第6段中也說了Epigenetic processes，但這一題的直接對(duì)應(yīng)還是出現(xiàn)在第7段里。原文中明確說到，表觀遺傳過程是與先天和后天都不相關(guān)的化學(xué)反應(yīng)。題干中的different from與tied to neither同義替換，由此確定答案為TRUE。

第5題答案是：A

對(duì)應(yīng)原文：第4段：when the English scientist Francis Galton first suggested the approach(and coined the phrase‘nature and nurture‘)

答案解析：第4段中提到，英國(guó)科學(xué)家Francis Galton首次提出這一方法，并發(fā)明了“先天和后天”這一短語。題干中invented a term與coined the phrase對(duì)應(yīng)，nature and nurture則對(duì)應(yīng)后面的內(nèi)容，由此確定答案為A。

第6題答案是：C

對(duì)應(yīng)原文：第12段：Having said that,Reed adds,the latest work in epigenetics promises to take our understanding even further.

答案解析：第12段中提到，Reed表示，表觀遺傳學(xué)最新的研究將進(jìn)一步加深我們的理解。上一段中也提到表觀遺傳學(xué)改變了人們對(duì)心臟病和精神分裂的看法。即對(duì)表觀遺傳學(xué)的研究將提升我們的知識(shí)，由此確定C為答案。

第7題答案是：B

對(duì)應(yīng)原文：第5段：Bouchard and his colleagues used this mountain of data…The key to their approach was a statistical concept called heritability

答案解析：這道題的關(guān)鍵在于statistical與mathematical的對(duì)應(yīng)。只要意識(shí)到這一組同義替換，就可以很輕易的確定B為答案。

第8題答案是：A

對(duì)應(yīng)原文：第4段：The idea of using twins to measure the influence of heredity dates back to 1875,when the English scientist Francis Galton first suggested the approach

答案解析：第4段開頭提到，利用雙胞胎衡量遺傳因素的影響的想法可以追溯到1875年。那時(shí)，英國(guó)科學(xué)家Francis Galton首次提出這種方法。題干中的pioneered與first同義替換，由此確定答案為A。

第9題答案是：B

對(duì)應(yīng)原文：第4段：the arrival of studies into identical twins who had been separated at birth and reunited as adults.Over two decades 137 sets of twins eventually visited Thomas Bouchard

答案解析：對(duì)出生之后分離的雙胞胎的研究是由Thomas Bouchard進(jìn)行的，由此確定B為答案。

第10題答案是：D

對(duì)應(yīng)原文：第7段：Epigenetic processes are chemical reactions…These reactions influence how our genetic code is expressed

答案解析：根據(jù)標(biāo)題定位到第7段，根據(jù)influence定位到后面這句話，由此鎖定reactions。但發(fā)現(xiàn)選項(xiàng)中并沒有能夠與之對(duì)應(yīng)的詞匯。由此往上尋找，發(fā)現(xiàn)these reactions指代的是chemical reactions，確定D為答案。

第11題答案是：B

對(duì)應(yīng)原文：第7段：These reactions influence how our genetic code is expressed:how each gene is strengthened or weakened,even turned on or off,to build our bones,brains and all the other parts of our bodies.

答案解析：順著上一題往下，原文中舉了骨頭，大腦以及身體其他部位的例子。B選項(xiàng)organs正好可以對(duì)它們進(jìn)行概括，由此確定答案為B。

第12題答案是：E

對(duì)應(yīng)原文：第9段：One way the study of epigenetics is revolutionizing our understanding of biology is by revealing a mechanism by which the environment directly impacts on genes.

答案解析：根據(jù)way這一原詞，以及reavealing和uncovering的對(duì)應(yīng)定位到第9段的這句話。affect與impact同義替換，由此確定答案為E environment。

第13題答案是：F

對(duì)應(yīng)原文：第9段：Studies of animals,for example,have shown that when a rat experiences stress during pregnancy,it can cause epigenetic changes in a fetus that lead to behavioral problems as the rodent grows up

答案解析：根據(jù)stress定位到這句話，題干中問的是哪方面會(huì)有問題，由此鎖定behavioral。選項(xiàng)F只是進(jìn)行了簡(jiǎn)單的詞性替換，迷惑性不大。

關(guān)于劍橋雅思11test4passage1答案及解析的內(nèi)容就到這里結(jié)束了，大家還有哪里不懂的呢？建議大家做題要將其完全吃透哦，這樣才能對(duì)自己有幫助。
