问题     The unhealthy ingredients and low nutrition content of the food can make you less active and lazy, new research shows. No surprises there.【C1】________, what is more shocking is that the energy-weakening effects of a junk food diet can persist,【C2】________after you switch to a healthy【C3】________.
    Two groups of female rats were fed different diets by researchers for a six-month period.  One group ate unprocessed foods such as corn and fish meal【C4】________the other ate a diet【C5】________to imitate junk food; high in sugar, and lower in【C6】________. While understandably the group eating the ’junk food’ diet gained more weight than the other, they also【C7】________from fatigue and became less active and less【C8】________—ie: lazier. In fact, those rats fed junk food took twice as many, and longer breaks during tasks than the rats eating a healthy diet, even tasks which【C9】________rewards.
    What is even more【C10】________is that switching these rats back onto a nutritious diet at the end of six months for nine days didn’t seem to reverse their weight gain or their ’learnt’ laziness. This could suggest that while an【C11】________case of bad food—say on holiday, will not have too much of a【C12】________effect if you generally eat a good diet and lead a healthy lifestyle. But those who eat a poor diet【C13】________the long term may actually become lazy and fatigued, as well as gaining weight and suffering the health consequences【C14】________being overweight.
    The research shows that switching【C15】________a healthy diet in the short term is unlikely to be【C16】________to reverse any of the side effects of a diet high in junk food. "Overweight people are often regarded as lazy and lacking【C17】________," says Blaisdell, a professor of psychology at UCLA "We【C18】________our results as suggesting that the idea commonly【C19】________in the media that people become fat because they are lazy is wrong. Our data suggest that diet-induced obesity is a cause,【C20】________an effect,, of laziness. Either the highly processed diet causes fatigue or the diet causes obesity, which causes fatigue."

选项 A、generated
B、handled
C、designed
D、created

答案A

解析 which指代tasks(任务),空格后为宾语rewards(奖励)。由even可知这些吃垃圾食品的小白鼠在所有的任务中都表现不佳,而用于试验的动物通常会养成条件反射,有奖励时会有更好的表现,因此选A项generated“产生”,可以与“奖励”构成合理的动宾关系。B项handled、C项designed及D项created代入文后,分别表示“处理奖励”、“设计奖励”及“创立奖励”,一一代入后语义上都不通顺。
