剛剛結(jié)束的2014年12月四級考試中，聽力第二部分（短文）的第一篇文章提到的神奇小故事，還有印象嗎？一對出生僅四個月就分開的雙胞胎，之后三十多年沒有見面，但他們的人生軌跡卻驚人的一致：都結(jié)過兩次婚，第一任太太的名字是一樣的等等。當真如此神奇？不如來看看專業(yè)研究人員怎么說吧。

Genes play a greater role in determining key personality traits like social skills and learning ability than the way we are brought up by our parents, researchers claimed.
研究人員表明，在決定諸如社交技能和學(xué)習(xí)能力的關(guān)鍵性格特征方面，與父母的養(yǎng)育方式相比較，基因扮演著更為重要的角色。

Researchers from Edinburgh University studied more than 800 sets of identical and non-identical twins to learn whether genetics or upbringing has a greater effect on how successful people are in life.
愛丁堡大學(xué)的研究人員以800多對同卵雙胞胎和異卵雙胞胎為對象，研究了成功的人生究竟是受遺傳的影響更大還是受成長的影響更大。

Participants were asked a series of questions about how they perceive themselves and others, such as "are you influenced by people with strong opinions?"

Writing in the Journal of Personality, the researchers found that identical twins were twice as likely as non-identical twins to share the same personality traits, suggesting that their DNA was having the greatest impact.
正如《人格期刊》所寫，研究人員發(fā)現(xiàn)，同卵雙胞胎擁有相同性格特征的可能性是異卵雙胞胎的兩倍，表明他們的DNA（在決定性格特征上）起到了最重要的作用。

Genetics were most influential on people's sense of self-control and also affected their social and learning abilities and their sense of purpose.
人們在自我控制方面、社交和學(xué)習(xí)能力方面以及使命感上，遺傳是最具影響力的因素。

Prof Timothy Bates, who led the study, said: "Previously, the role of family and the environment around the home often dominated people's ideas about what affected psychological wellbeing. However, this work highlights a much more powerful influence from genetics."
帶領(lǐng)整個研究團隊的提莫斯·貝提斯教授說：“以前常常認為家庭角色和環(huán)境是影響人們心理健康的因素，但這次的研究表明，遺傳方面的影響更為顯著?！?/div>
