问题     Biology may not be destiny, but genes apparently have a far greater influence on human behavior than is commonly thought. Similarities ranging from phobias to hobbies to bodily gestures are being found in pairs of twins separated at birth.
    Professor Bouchard of the University of Minnesota reports that so far, exhaustive psychological tests and questionnaires have been completed with approximately 50 pairs of identical twins reared apart, 25 pairs of fraternal twins reared apart, and comparison groups of twins reared together. Studies show that twins rend to have similar mannerisms, gestures, speed and tempo in talking, habits and jokes.
    Many of the twins dressed in similar fashion. One pair had practically the same items in the toilet cases, including the same brand of cologne and a Swedish brand of toothpaste.
    Twins also tend to have similar hobbies and interests—a male pair had similar workshops in their basements and a female pair had strikingly similar kitchen arrangements.
    Bouchard doesn’t have enough information on abnormal behavior or psychopathology to make generalizations, but he has found repeated similarities. One pair of women were both very superstitious; another pair would burst into tears at the drop of a hat, and questioning revealed that both had done so since childhood.
    Overall the emerging findings of the study constitute a powerful rebuttal to those who maintain that environmental influences are primary shaping forces of personality. The textbooks are going to have to be rewritten, Bouchard predicts.
Professor Bouchard seems to be convinced that______.
选项 A、the existing theories about the shaping of personality are valid
B、the text books should be rewritten because they are out of date
C、one’s environment is more important than his genes in the shaping of his personality
D、one’s genes are more important than his environment in the shaping of his personality
答案D
解析 细节题。从最后一段可知，Bouchard认为教科书应该改写并非是因为其过时了，而是他所发现的结果对那些认为环境比基因更重要的理论是一个有力的驳斥，即他认为基因在形成个性的过程中，远比环境重要。因此本题正确答案为D。
