6．Happiness is in your genes，it seems，according to a research that shows the more
people in a country who have a particular gene，the happier the nation will be．The FAAH gene，the DNA in question，makes a protein that affects feelings of pleasure and pain．
People with a particular version of it tend to be cheerier souls．
The researchers believe that the finding can help explain why some of the world's
poorest nations are also the happiest．The team from Bulgaria looked at whether there was a connection between the level of the FAAH gene in a population and the number of people who said they were very happy in the global study of life satisfaction．Sweden，one of the happiest countries in Europe and in the world，has lots of happy DNA．Some 26.3per cent of Swedes have the happiness gene，compared t0 23per cent of the British，21per cent of the French and 20per cent of Germans．The happiness gene is even rarer in southern Europe，where it is found in 18per cent of Greeks and just 12per cent of Italians．In contrast，the people in Iraq and Jordan are among the least likely to rate themselves as very happy and also have the lowest levels of the gene．
But the gene and optimism don-t always go hand in hand．For instance，Russians
score very low on happiness，despite having the right DNA，the Journal of Happiness
Studies reports．Climatic differences are also found to be closely associated with national differences in happiness．Study co-author Michael Minkov said，"We can notice the high occurrence of the gene in equatorial（赤道的） and tropical environments in South America and Africa，and the lower occurrence of it around the Mediterranean Sea than in Northern Europe．"4'Genetics is not the only determining factor （因素） of happiness，"A spokesman for the journal's publisher said，"The economic and political difficulties continuously experienced by Eastern European nations contribute to the very low happiness scores of Russians．Nations not blessed with the right DNA aren't necessarily miserable-happiness can still rise and fall for other reasons．"
32．The underlined word"it"in Paragraph l refers toD．
A．happiness
B．life satisfaction
C．the protein in question
D．the FAAH gene
33．Which country has the highest percentage of the happiness genes？C
A．Greece．B．Germany．C．Britain．D．Iraq．
34．What can we infer from the text？A
A．Climate has much to do with happiness．
B．The poorest countries are actually the happiest．
C，Genetics matters most to determine happiness．
D，Russians are not happy since they lack happy DNA．
35．The best title for the text isB
A．Researches on Genetic Science
B．Factors to Affect Happiness
C．Reasons for National Differences
D．The Happiest Countries．
分析 这是一篇科普文．主要是写影响快乐的因素有FAAH基因，有某种特殊基因的人会更加快乐一些．还还有气候因素也会影响快乐的．
解答 DCAB
32 D 事实细节题．根据第一段"The FAAH gene，the DNA in question，makes a protein that affects feelings of pleasure and pain．People with a particular version of it tend to be cheerier souls．"可知it指的是FAAH 基因，D为正确答案．
33 C 事实细节题．根据第二段"Some 26.3 per cent of Swedes have the happiness gene，compared t0 23 per cent of the British，21 per cent of the French and 20 per cent of Germans．The happiness gene is even rarer in southern Europe，where it is found in 18 per cent of Greeks and just 12 per cent of Italians．In contrast，the people in Iraq and Jordan are among the least likely to rate themselves as very happy and also have the lowest levels of the gene．"可知英国有最高的幸福基因的比率，C为正确答案．
34 A 事实细节题．根据第三段"Climatic differences are also found to be closely associated with national differences in happiness．"可知气候的不同与不同国家的快乐基因有关系，A为正确答案．
35 B 主旨大意题．根据第一段的"Happiness is in your genes，it seems，according to a research that shows the more people in a country who have a particular gene，the happier the nation will be．"以及第三段"Climatic differences are also found to be closely associated with national differences in happiness．"可知本文主要是写影响快乐的因素有FAAH基因，有某种特殊基因的人会更加快乐一些．还还有气候因素也会影响快乐的，B为正确答案．
