Fitness trackers are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. Many people wear them in the hope of losing weight. But a new study finds the electronic device probably does not help with weight loss, according to the researchers from the University of Pittsburgh in the US.
The University of Pittsburgh research team watched two groups of individuals. The first group wore a fitness tracker and took part in health counseling. The researchers compared this group with people who only took part in health counseling. The study found that those who simply had health counseling lost more weight than those who had counseling and wore a fitness tracker. In fact, those who only spoke with the health experts lost nearly six kilograms. Those who used a fitness tracker lost only three and a half kilograms.
John Jakicic is the lead researcher. He is also chairman of the university’s Department of Health and Physical Activity. He questioned the use of electronic devices as tools for weight control and conducted a study which involved 470 people between the ages of 18 and 35. Some of them were overweight, while others were heavier and considered obese. Over three fourths of the people were women. All people were told to have their weight measured once every six months over the two- year study. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a wearable fitness tracker. Eighteen months later, both groups showed significant improvements in body fitness. However, when it came to losing weight, the people who only spoke with the health experts lost nearly twice as much weight.
1. Which of the following methods is used by the researchers?
A. The prediction method.
B. The comparison method.
C. The reference method.
D. The measurement method.
(B)
2. From John Jakicic’s research, we can know that ______.
A. fitness trackers are very useful for those who want to lose weight
B. we can rely on electronic devices to control weight
C. electronic devices are not that useful as we thought in helping people lose weight
D. fitness trackers are designed to record your physical activity
(C)
3. What do you think the author will discuss next?
A. Why they did this research.
B. What advantages the wearable fitness tracker can bring us.
C. Why the former group members lost more weight than the latter.
D. How to choose a suitable wearable fitness tracker.
(C)

答案： 1. B 归纳概括题。由第二段和第三段可知，研究者们使用了对比的研究方法。因此选 B。
2. C 细节理解题。由第二段最后两句以及第三段最后一句的实验结果可以推断出，健身追踪器在减肥方面的作用并没有人们想象中的那么大，C 项正确。D 项是健身追踪器的功能，不是实验结果。因此选 C。
3. C 推理判断题。文中的实验目的是研究健身追踪器是否有助于减肥。文章结尾处的实验结果表明，进行健康咨询的那组减肥效果更明显，由此可以推断出作者接下来可能会探究为什么会出现这种现象，因此选 C。
