2009年考研第二篇文章再次出現(xiàn)了這樣的題目,并且思路和意圖更加明顯。
But some observers are skeptical, “There is a kind of false precision being hawked by people claiming they are doing ancestry testing,” says Troy Duster, a New York University sociologist. He notes that each individual has many ancestors-numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father’s line or mitochondrial DNA, which a passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.
28. Skeptical observers believe that ancestry testing fails to _____.
A)trace distant ancestors
B)rebuild reliable bloodlines
C)fully use genetic information
D)achieve the claimed accuracy
依然先看一下題干:持懷疑態(tài)度的觀察家認(rèn)為家譜檢測(cè)未能_____.問題同樣是在問文中人物的觀點(diǎn),因此這個(gè)題干直接就把我們帶到了段落的第一句But some observers are skeptical, “There is a kind of false precision being hawked by people claiming they are doing ancestry testing,” says Troy Duster, a New York University sociologist.但有些觀察家對(duì)此表示懷疑的。紐約大學(xué)的社會(huì)學(xué)家特洛伊.達(dá)斯特說,“聲稱自己在做家譜測(cè)試的人正在吹噓一種虛假的精確性!蓖瑯拥览韇elieve就是題干中的says,這個(gè)社會(huì)學(xué)家就是懷疑者中的一個(gè),他的觀點(diǎn)代表的就是懷疑者的觀點(diǎn),因此我們很清晰可以看出D選項(xiàng)---達(dá)到(檢測(cè)者)所聲稱的精確度,為對(duì)剛才那句話的同意替換,是正確答案。我們要是以后面的內(nèi)容作為選擇依據(jù)我們將被迷惑項(xiàng)搞得痛苦不堪,尤其是選項(xiàng)C。
我們先解決到A和B
A)trace distant ancestors
追溯年代久遠(yuǎn)的祖先
文中說most ancestry testing only considers a single lineage只考慮了單線的祖先,而不是說找不到年代久遠(yuǎn)的祖先,輕松排除。
B)rebuild reliable bloodlines
重建可靠的血統(tǒng)譜系
文中說This DNA can reveal genetic information about only one or two ancestors,這種測(cè)試只能告知不完全的血統(tǒng)譜系,而不是說不能重建可靠的血統(tǒng)譜系。
最后看看C選項(xiàng),這個(gè)選項(xiàng)在教育部的考試分析中我們可以看到這個(gè)選項(xiàng)時(shí)是錯(cuò)選率最高的,在錯(cuò)選答案中占到了89% 3也就是這個(gè)題做錯(cuò)的同學(xué)幾乎都是錯(cuò)選的這個(gè)選項(xiàng)。
Fail to C)fully use genetic information
(未能)完整的利用基因信息
文章中Yet most ancestry testing only considers a single lineage只考慮了單線的祖先;This DNA can reveal genetic information about only one or two ancestors,這種測(cè)試只能告知不完全的血統(tǒng)譜系;幾乎所有的線索都指向了答案C。但先仔細(xì)對(duì)比一下這兩種說法:
1)Fully use genetic information ; 2)use full genetic information;
前一個(gè)強(qiáng)調(diào)的是使用這個(gè)動(dòng)作的完整性;后一個(gè)強(qiáng)調(diào)的是使用對(duì)象的完整性。
顯然你就知道C選項(xiàng)是不對(duì)的了。
但是在考場(chǎng)上很少有同學(xué)能思考到這個(gè)層次,在D和C之間徘徊的時(shí)候請(qǐng)牢牢地記住了,問題在問觀點(diǎn)是什么,就不要去選對(duì)觀點(diǎn)的分析了。
再次強(qiáng)調(diào):緊扣題干,找準(zhǔn)路標(biāo),問觀點(diǎn),就找觀點(diǎn)。
