2015考研英语阅读传递快乐的使者

　　The adolescents in Dr De Neves study were asked to grade themselves from very satisfied tovery dissatisfied. Dr De Neve found that those with one long allele were 8% more likely thanthose with none to describe themselves as very satisfied; those with two long alleles were 17%more likely.

　　德?内弗博士在研究中要求青少年在非常满意到非常不满之间对自己作出评价。德?内弗博士发现，拥有一个长型基因的人对自身评价非常满意的比例比没有长型基因的人多8%;而拥有两个长型基因的人则多17%。

　　Which is interesting. Where the story could become controversial is when the ethnic origins ofthe volunteers are taken into account. All were Americans, but they were asked to classifythemselves by race as well. On average, the Asian Americans in the sample had 0.69 longgenes, the black Americans had 1.47 and the white Americans had 1.12.

　　以上现象相当有趣。而研究有争议之处在于，志愿者的种族也被考虑了进去。所有志愿者都是美国人，但他们同样被要求区分自己属于哪个种族。在样本中，平均而言，亚裔美国人拥有0.69个长型基因，黑人美国人拥有1.47个，白人美国人有1.2个。

　　That result sits comfortably with other studies showing that, on average, Asian countries reportlower levels of happiness than their GDP per head would suggest. African countries, however,are all over the place, happinesswise. But that is not surprising, either. Africa is the mostgenetically diverse continent, because that is where humanity evolved . Black Americans, mostly the descendants of slaves carried away froma few places in west Africa, cannot possibly be representative of the whole continent.
