听力原文：Okay, Alan and I are ready to get going. We have the food and most of the supplies, and we've put both kayaks on the roof of your car. You should drive ahead of us—we'll follow closely behind you in case... you know, just in case. I don't think I need to tell you to drive with care—you'll feel the wind swaying your car a little bit, but don't worry: the boats are solidly secured. The main thing for you to be aware of is if we go through any drive-throughs or, I don't know, if you want to pull into a parking garage. Just be aware of the height limits— I think with the boats on top you're about seven feet tall, so be aware of that. Urn... I'll have my cell phone on, so give me a call if you want. I really don't think you'll have any trouble driving the car, just... urn, as I said, drive carefully and be aware of height limits. Okay, see you at the lake!

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 didnt 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."
