D． Both our genes and our experiences make us who we are. 解析 主旨大意題。 genes. Except for identical twins(同卵雙胞胎 ), no one has the same bination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make. But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births—some are identical and others are non identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non identical twins are more like ordinary brothers and sisters. Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short sightedness, are mostly resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non identical twins. Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill seekers and get into risk taking and adventurous take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this. We could ask， “ Are our lives determined by our genes or our upbringing？ ” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are. 【語篇解讀】 本文主要介紹基因和生活經(jīng)歷對人的外貌、性格等的形成所起的作 用。通讀全文，可知科學(xué)家們克隆了一只已經(jīng)滅絕的比利牛斯野生山羊，但這只羊在出生不久就死了，故 D 項最適合作文章標(biāo)題。 答案 C 39． What39。 答案 D 38． We can conclude from the passage that________.
