细节题
A busy brain can mean a hungry body We often seek food after focused mental activity, like preparing for an exam. Researchers think that heavy bouts of thinking drain energy from the brain, whose capacity to store fuel is very limited.
So the brain, sensing that it may soon require more calories to keep going, apparently stimulates bodily hunger, and even though there has been little in the way of physical movement bodily hunger, and even though there has been little in the way of physical movement or calorie consumption, we eat this process may partly account for the weight gain so commonly seen in college students.
Scientists at the University of Alabama at Birmingham and another institution recently experimented with exercise to counter such immoderately post-study food consumption.
Gary Hunter, an exercise physiologist at U.A.B., oversaw the study Hunter notes that tough activity both increases the amount of blood sugar and lactate (乳酸盐)—a byproduct of intense muscle contractions (收缩)—circulating in the blood and increases blood flow to the head. Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel-rich blood during exercise could feed an exhausted brain and reduce the urge to overeat.
Thirty-eight healthy college students were invited to U.A.B.’s exercise lab to report what their favorite pizza was. At a later date, the volunteers returned and spent 20 minutes dealing with selections from college and graduate-school entrance exams. Next, half the students sat quietly for 15 minutes, before being given pizza The rest of the volunteers spent those 15 minutes doing intervals on a treadmill: two minutes of hard running followed by about one minute of walking, repeated five times. Hunter says, that should stimulate the release of sugar and lactate into the bloodstream. These students were then allowed to gorge on pizza, too But by and large, they did not overeat. In fact, the non-exercisers, however, consumed about 100 calories more.
The study has limitations, of course We only looked at lunch Hunter says;the researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as running, although Hunter says they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hunger’s call.
According to the passage, may cause many college students to overeat and gain weight.
a lot of energy-consuming mental activities
","numerous physical movements or calorie burning
","failure to resist the temptation of delicious food
","bodily hunger caused by physical growth
"]细节理解题。根据第一段 “We often seek food after focused mental activity, like preparing for an exam. Researchers think that heavy bouts of thinking drain energy from the brain, whose capacity to store fuel is very limited. (我们经常在专注的脑力活动后寻找食物，比如准备考试。研究人员认为，大量的思考会消耗大脑的能量，而大脑储存能量的能力非常有限。)” 以及第二段 “So the brain, sensing that it may soon require more calories to keep going, apparently stimulates bodily hunger, and even though there has been little in the way of physical movement or calorie consumption, we eat. This process may partly account for the weight gain so commonly seen in college students. (所以，大脑感觉到它可能很快就需要更多的卡路里来维持运转，显然会刺激身体产生饥饿感，而且即使几乎没有身体运动或卡路里消耗，我们也会进食。这个过程可能在一定程度上解释了大学生中常见的体重增加现象。)” 可知，大量消耗能量的脑力活动可能导致很多大学生过度进食并增重。故选A。
The underlined word “counter” is closest in meaning to .
stimulate
","maximize
","balance
","prevent
"]词义猜测题。根据第二段 “So the brain, sensing that it may soon require more calories to keep going, apparently stimulates bodily hunger, and even though there has been little in the way of physical movement or calorie consumption, we eat. This process may partly account for the weight gain so commonly seen in college students. (所以，大脑感觉到它可能很快就需要更多的卡路里来维持运转，显然会刺激身体产生饥饿感，而且即使几乎没有身体运动或卡路里消耗，我们也会进食。这个过程可能在一定程度上解释了大学生中常见的体重增加现象。)” 划线词后面的内容 “such immoderately post-study food consumption. (这种过度的课后 (学习后) 进食行为。)” 可知，大量消耗能量的脑力活动可能导致很多大学生过度进食并增重，所以阿拉巴马大学伯明翰分校和另一所机构的科学家最近进行了运动实验，以阻止这种学习后过度进食的现象。所以划线单词counter意为 “阻止，防止”。故选D。
What can be inferred from the passage?
Running is more beneficial than walking.
","Sweating in exercise can make people hungrier.
","The amount of blood sugar and lactate can affect people’s appetite.
","When the brain feels exhausted, people tend to do exercise for relaxation.
"]推理判断题。根据第四段中 “Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel-rich blood during exercise could feed an exhausted brain and reduce the urge to overeat. (因为大脑使用糖和乳酸作为燃料，研究人员想知道，运动期间富含燃料的血液流动增加是否能为疲惫的大脑提供营养，并减少暴饮暴食的冲动。)” 及最后一段中 “They also cannot tell whether other types of exercise would have the same effect as running, although Hunter says they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hunger’s call. (他们也无法确定其他类型的运动是否会产生与跑步相同的效果，不过亨特表示，他们猜测如果一项活动能让人出汗，那它也应该会使血糖和乳酸盐水平升高，从而为大脑提供能量，并减轻饥饿感。)” 可推知，血糖和乳酸盐的量会影响人们的食欲。故选C。
