To master the violin takes 10,000 hours of practice. Put in that time and【C1】______will follow. This, at least, is what many music teachers tell their pupils. Psychologists are more【C2】______. Some agree practice truly is the thing that【C3】______experts from beginners, but others suspect genes play a role, too, and that【C4】______the right genetic make-up even 20,000 hours of practice would be pointless. A study just published in Psychological Science, by Miriam Mosing of the Karolinska Institute, in Sweden, suggests that the skeptics are【C5】______. Practicing music without the right genes to【C6】______that practice up is【C7】______useless. Dr Mosing drew her【C8】______in a time-honored way—by studying twins. She and her colleagues【C9】______1,211 pairs of identical twins (who share all their genes) and 1,358 pairs of fraternal twins (who share half). They asked each participant【C10】______he or she played a musical instrument or actively【C11】______singing. Those who did were asked to【C12】______how many hours a week they had practiced at different ages. From this Dr Mosing was able to calculate a【C13】______for each individual"s lifetime practice. Anyone who did not play an instrument or sing got no point. Next, Dr Mosing tested her volunteers" musical a-bilities. Expert musicians are exceptionally good at【C14】______differences in pitch, melody and rhythm. She therefore expected to find that if someone had put in【C15】______practice time his musical ability would be as high as an expert"s. But that was not true. In fact, there appeared to be no【C16】______between practice and musical ability of the sort she was measuring. A twin who practiced more than his genetically identical co-twin did not appear to have better musical abilities as a result. In one case the difference between two such twins was 20,228 hours of practice,【C17】______the pair"s measured musical abilities were found to be the same. That is not to say practice has no【C18】______. Playing an instrument and singing are physical skills, and do take a long time to【C19】______. And Dr Mosing has shown that musical ability has a big genetic【C20】______.
单选题
【C1】
【正确答案】
B
【答案解析】解析：and表示顺接关系，故可认为…will follow是Put in that time的结果。上句的表明，花1万个小时来拉小提琴(Put in that time所指代的事情)，就能学会小提琴。B项expertise“专长”可指“会拉小提琴”这项音乐技能，与master呼应。
