The findings, the first to show differences in very young babies, suggest there is a biological basis to their preferences. Psychologists Dr. Brenda Todd from City University London carried out an experiment involving 90 infants aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were typically boys toys: a car, a digger, a ball and a blue teddy. The rest were girls toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the twoand threeyearolds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents view on which toys were more suitable for boys or girls, and the childrens choice.Dr. Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given toys that go while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts (本能), while girls prefer warmer colors such as pink, the color of a newborn baby.”一项研究表明婴儿的偏好基于生理基础。1Baby boys and girls have different toy preferences probably because_.Ababy boys are much more activeBbaby girls like bright colors moreCthere is a natural difference between themDtheir parents treat them differently答案：C细节理解题。文中第一段最后一句话，表明C项正确。2.
