A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds the fitness tracker probably does not help with weight loss.
The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.
The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”
The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.
Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.
1.All the subjects in the study were asked to ________.
A. start on a high-calorie diet B. wear a fitness tracker
C. increase physical activities D. record their heart rates
2.Why does Jakicic think the findings are important?
A. Wearing fitness trackers hardly helps people lose weight.
B. Physical activity and diet have no effect on weight loss.
C. Handling obesity requires effective long-term treatments.
D. There are great differences in fitness between both groups.
3.What can we infer about the study mentioned in the text?
A. The study went on for about two years.
B. More than 120 men took part in the study.
C. Health counseling helps lose almost 6 kilograms.
D. Wearing a fitness tracker is useful for keeping slim.
4.The purpose of the text is to ________.
A. describe how the researchers were conducting the study
B. indicate regular counseling for weight control is necessary
C. convince readers to wear fitness trackers for weight control
D. warn women are more likely to suffer from weight problems

In a study published in the U. S. journal Science, researchers from the Chinese Academy of Agricultural Sciences(CAAS) and the University of Florida identified the chemical combinations and genetic recipe for better tomato flavor(味道).
“In recent years, consumers often complain that the modern tomato is less flavorful than it once was” said co-principal researcher Sanwen Huang. “Our results provide a practical road map for breeding tomato varieties with better flavor.”
For the study, a 170-person consumer group was created to evaluate 160 tomatoes representing 101 varieties, based on qualities such as “overall liking” and “flavor degree”. The results pointed to dozens of chemical compounds of interest, and further research using a statistical model discovered 33 flavor compounds connected with consumer liking, such as glucose(葡萄糖). The reason why modern tomatoes don’t taste good anymore is that a total of 13 of these flavor-associated compounds “were significantly reduced in modern varieties,” their paper wrote. Moreover, the researchers found that smaller fruit tended to have greater sugar content, suggesting that “selection for more sizable tomatoes has cost sweetness and flavor”.
Based on this knowledge, Huang and Professor Harry Klee of the University of Florida studied the whole genomes of 398 varieties of tomato, identifying about 250 positions of genes on a chromosome(染色体), which controlled tomato flavor.
“We’re just fixing what has been damaged over the last half century to push them back to where they were a century ago,” said Klee in a statement. “We can make the supermarket tomato taste noticeably better.” Klee said new tomato varieties with better flavor could be ready in three to four years. In addition, “the genes and pathways identified here in the tomato almost certainly point to pathways worth researching for improvement of flavor quality in other fruit crops,” they wrote.
1.According to the text, the study ________.
A. was carried out just through a survey
B. was conducted by Chinese researchers themselves
C. was completely focused on the genes of different tomatoes
D. was done with the background of declining flavor of tomatoes
2.The researchers have found that ________ in the study.
A. bigger tomatoes are much sweeter
B. some genetic positions affect the taste of tomatoes
C. some chemical compounds make tomatoes less tasty
D. a total of 13 flavor-associated compounds make tomatoes appealing in taste
3.What is the influence of the study according to the text?
A. The study lays the foundation for further researches to improve other fruit crops’ flavor.
B. The study makes it possible for us to have noticeably more tasty tomatoes next year.
C. The study provides a road for where to plant tomatoes with better flavor.
D. The study has fixed all the genes of existing tomatoes.

According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
1.What is the recent study mainly about?
A.Food safety. B.Movie viewership.
C.Consumer demand. D.Eating behavior.
2.What does the underlined word “beanpoles” in paragraph 1 refer to?
A.Big eaters. B.Overweight persons.
C.Picky eaters. D.Tall thin persons.
3.Why did the researchers hire the actor?
A.To see how she would affect the participants.
B.To test if the participants could recognize her.
C.To find out what she would do in the two tests.
D.To study why she could keep her weight down.
4.On what basis do we “adjust the influence” according to the last paragraph?
A.How hungry we are. B.How slim we want to be.
C.How we perceive others. D.How we feel about the food.
