　　2015考研英語一的完形填空原文依然是來源于網(wǎng)站。我們還記得2014年考研英語一的完形就是直接來源于網(wǎng)站，而且竟然還是河北唐山的高三模擬考題。文都教育老師第一時間找到了今年完形的題源，來自于外文網(wǎng)站Givology，原文題目為：DNA of Friendship: Study Finds We are Genetically Linked to Our Friends，DNA友誼：研究發(fā)現(xiàn)我們在基因上和我們的朋友有著千絲萬縷的聯(lián)系。作者：Jayalakshmi K，發(fā)表時間為：July 15, 2014。文章發(fā)表時間為2014年的7月15號，依然延續(xù)了近年來時效性強的風格。

　　無論是考研輔導老師還是考研學子，人們大多認為，近兩年的完形文章相對于前幾年而言簡單了很多，文章的簡單與否，其實對于真正最后出來考研英語的分數(shù)到底是多少，其間并沒有一個非常正相關的關系，本質和核心在什么地方? 在透過這些文章的背后，我們要去掌握著什么樣的能力? 有兩點問題是可以明確的：第一，完形填空整體的難度偏簡單了，并且出題思路穩(wěn)定;第二，近四年考研文章的整體趨勢就是實效性不斷地增強，經(jīng)常是從前幾個月的《經(jīng)濟學人》這樣的一些雜志當中或熱門學習研究網(wǎng)站當中，摘取文章，并且對它進行改寫。

　　所以還是建議2016考研的考生，養(yǎng)成經(jīng)常閱讀英文的習慣，經(jīng)常讀一些社會科學和自然科學類的雜志或網(wǎng)站文章，真正提高自己的英語閱讀理解水平，這才是必經(jīng)之路!

　　(文都附)Givology網(wǎng)站2015完形原文：

　　We have more genes in common with people we pick to be our friends than with strangers. Though not biologically related, friends are as "related" as fourth cousins, sharing about 1% of genes. That is what a study published from the University of California and Yale University in the Proceedings of the National Academy of Sciences, has concluded。

　　The study is a genome-wide analysis conducted on 1932 unique subjects which compared pairs of unrelated friends and unrelated strangers. The same people were used in both samples. While 1% may seem insignificant, it is not so to a geneticist. As co-author of the study James Fowler, professor of medical genetics at UC San Diego says, "Most people do not even know their fourth cousins but somehow manage to select as friends the people who resemble our kin."

　　The team also developed a "friendship score" which can predict who will be your friend based on their genes. The study also found that the genes for smell were something shared in friends but not genes for immunity. Why this similarity in olfactory genes is difficult to explain, for now. Perhaps, as the team suggests, it draws us to similar environments but there is more to it. There could be many mechanisms working in tandem that drive us in choosing genetically similar friends rather than "functional kinship" of being friends with benefits!

　　One of the remarkable findings of the study was that the similar genes seem to be evolving faster than other genes. Studying this could help understand why human evolution picked pace in the last 30,000 years, with social environment being a major contributory factor。

　　The findings do not simply corroborate people's tendency to befriend those of similar ethnic backgrounds, say the researchers. Though all the subjects were drawn from a population of European extraction, care was taken to see that all subjects, friends and strangers were taken from the same population. The team also controlled the data to check ancestry of subjects。
