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."
【C5】

选项 A、served
B、aimed
C、meant
D、made

答案B

解析 前面提到一组小白鼠吃未经加工的食物即健康食品,而这一组就要吃“垃圾食品”。据推测,实验人员试图使这组的食物仿制成人类的垃圾食品。B项aimed与to搭配表示“努力;试图”。A项served通常与as搭配表示“起……作用”。C项meant to表示“打算做某事”,D项made to表示“做……”,都不合句意逻辑,均不能作为a diet的后置定语。
