Researchers at UCLA Medical Center found that a 12-minute bed-side visit with a dog can help reduce anxiety levels by 24 percent in heart failure patients, compared to a 10 percent drop when patients had a visit from a human volunteer, and no drop in patients who had no visit.

Results of the 76-patient study were presented last week. The study was supported by a non-profit (非盈利)organization which promotes human-animal interaction and connection. In the study, effects of dog and volunteer visits were compared with those of volunteers only, and with patients who had no visits and stayed at rest. Patients were asked to answer a list of questions before and after the visits. The results suggested improved heart function, and the most obvious reaction was seen in anxiety levels.

“The first thing you notice is that the patient’s facial expression, changes to a smile and the pressure of the world seems to be lifted off their shoulders,” study author Kathy Cole said. Feelings of disappointment and helplessness are common among heart patients, Cole said, and just three nights in a hospital is enough to make some patients feel anxious and uncomfortable. During the visit, the furry friend is allowed to lie on the bed next to the patient with its head within two feet of the patient’s. Most patients petted the dog, while others talked about the dog with human volunteers in conversation. 　　

Dogs used in the study are specially trained dogs that go through a series of trainings. There are different kinds of dogs. Researchers used everything from Bernese mountain dogs to small schnauzers. However, a dog doesn’t have to be specially trained to have a calming effect on a person. In fact, the animal doesn’t even have to be a dog in order to help. “As long as the animal has meaning to the patient, or a relationship with the patient, it can help calm the patient,” Cole said.

1.We learn from the text that heart patients benefit most from visits by___________.

A.a volunteer on his own B.a well-trained dog alone

C.a non-profit organization D.a volunteer with a dog

2.The study shows that, for heart patients, __________.

A.their recovery depends on contact with animals

B.their heart pressure reduces if they stay at rest

C.their contact with animals improves their condition

D.their anxiety is reduced if they stay longer in hospital

3.According to Cole, the change of patients’ expression on the face indicates that_________.

A.they are mentally comforted B.they are happy with the experiment

C.their treatment time may be shortened D.their heart function is returning to normal

4.This report concentrates on__________.

A.the treatment of heart disease B.the cure power of animals

C.the relationship between dogs and humans D.the promotion of human-animal interaction

A team of researchers at the University of Illinois at Chicago found that too many kids are eating too much pizza and too many calories are doing harm to children’s health.

“There are a lot of takeaways from the study. But the biggest thing is that parents are serving their kids too much pizza,” said Dr.William Dietz, one of the study’s authors and the director of the Sumner M. Redstone Global Center for Prevention and Wellness at the Milken Institute of Public Health at the George Washington University.

The researchers used data from the National Health and Nutrition Examination Survey, which tracked the diets of more than 11,000 children and teenagers. Researchers figured how many children eat pizza in the United States, how often they eat it, and how much they eat when they do.

Pizza, pretty alarmingly, is the second leading source of calories in the diets of America’s children, next only to grain desserts, such as cookies and other sweets. On any given day, roughly 20 percent of all children aged 2 to 11 and adolescents aged 12 to 19 eat pizza. And when they do, they eat a lot of it. When children eat pizza, they eat roughly 400 calories, according to the study. For teenagers, it’s upwards of 600 calories.

All that is pretty problematic, according to Dietz largely because kids don’t tend to balance the pizza slices with salads, vegetables and other more nutritional(有营养的) foodstuffs. Days on which children and teenagers eat pizza are not only associated with considerably higher intakes of fat, but also, quite simply, with more food: on average, children consume 84 extra calories on the days they eat pizza, while adolescents consume an extra 230 calories.

“When you eat extra calories and don’t compensate(抵偿) for them at another point of the day or week, it can lead to weight gain and even obesity.”Dietz said.

There is a Silver lining. Pizza consumption is still too high by nutrition standards, but it’s lower than it used to be. Consumption(消费) fell by roughly 25 percent between 2007 and 2016, according to the study. Much of that has come at dinner where it's fallen by 40 percent for children and about 33 percent for teenagers. It’s unclear whether the decline has been in connection with a growing concern over obesity, especially among the country’s youth.

But the drop in pizza consumption, while significant hasn’t been big enough “It’s a positive trend,” Dietz said. “But we’re not quite them yet.”

It’s easy to see the appeal of pizza. It’s cheap. Parents can buy a lot of pizza for not a lot of money. Besides, they can buy pizza from a chain shop, a mom-and-pop store or a grocery freezer. And it’s universally loved. The estimated 3 billion pizza eaten each year in the United States is a proof of the food’s unmatched popularity. Given how much the country loves pizza, what’s to be done? Dietz suggests pizza with smaller serving sizes and healthier toppings(配料). “We’re not suggesting that kids avoid pizza altogether.” said Dietz. “But when parents serve it, it’s important that they understand it’s extremely caloric. They should serve smaller pizza, or at least smaller slices.”

1.According to the study, the problem with kids is that 　　　 .

A. they are overweight　　 B. they have too many takeaways

C. they are fed too much pizza　　 D. they have very bad health

2.How did the researchers get the result?

A. Through interviewing.　　 B. By analyzing data.

C. By tracking kids’ diets.　　 D. Through experimenting.

3.We know from the passage that when kids eat pizza, 　　　　 .

A. they usually don’t eat other food　　 B. they eat less of other food

C. they are not likely to balance their diet　　 D. they usually eat with vegetables

4.What does the underlined part a silver lining in Paragraph 7 probably mean?

A. Something hopeful　　 B. Something valuable.

C. Something miserable.　　 D. Something successful.

5.What’s the key message of the last paragraph?

A. Pizza consumption fell significantly in America.

B. Pizza has many advantages over other food.

C. Eating too much pizza can lead to failing health and obesity.

D. The pizza problem may be improved through its size and topping.

Researchers found animals lovers exercise their pet twice a day for 24 minutes each time --- a total of five hours and 36 minutes a week. On top of that, the average dog owner also takes part pet out to take three long walks each week adding another two hours and 33 minutes to the total. But those without a dog spend an average of just one hour and 20 minutes per week exercising by going to the gym or heading out for a walk or jog. And almost half of non-pet owners admit they take no exercise.

A spokesperson said the difference between the two was that going to the gym can feel like a boring task while dog-walking can be far more enjoyable. “Having a couple of short walks every day soon adds up and this research shows that it amounts to more time than people spend in the gym,” he said. And gym goers exercise inside an air-conditioned gym, while dog walkers are able to jog for miles and enjoy fresh air when admiring the Great British countryside.”

The study of 5,000 people, including 3,000 dog owners, showed that 57 percent of those considered walking the dog as their main form of exercise. More three quarters said they would rather take their dog for a walk than go to the gym. A total of 86 percent said they enjoyed taking their pet out each day, with just 22 percent saying they sometimes saw it as a boring task. But only 16 percent of respondents said they enjoyed exercising in the gym, while almost 70 percent considered it a boring task.

The survey shows that having a dog to walk actually encourages regular exercise, with 60 percent of pet owners saying they always go for a walk with their dog --- even when time is valuable.

1.How long do dog owners walk their dog on average each week according to the study?

A.One hour and 20 minutes B.Five hours and 36 minutes

C.Two hours and 33 minutes D.Eight hours and 9 minutes

A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.

The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.

An addiction that doesn’t discriminate(歧视)

“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.

Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.

Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.

In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.

“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.

1.The study led by Professor Mark Weiser shows that ________.

2.According to the passage, a smoking man’s IQ is most likely to be ________.

3.What can be learned from the passage?

4.What is the meaning of the underlined part “An addiction that doesn’t discriminate”?

Researchers have found that most of our tiredness comes from our mental attitudes (心态). One of England’s doctors, J.A. Hadfield, says, “ 　　　　　　 1.　　　　 . In fact, tiredness of completely physical origin (缘由) is unusual.” So, remember -- the key to improved productivity is learning to relax. Here are some suggestions for you.

Relax form time to time

2.　　　 . It is said that if you want to master the art of relaxation, study the cat. Think about it. Have you ever seen a tired cat, or a cat with a nervous break-down? You will probably avoid this kind of feeling if you learn to relax as the cat does.

3.　　　　

Remember that tensions (紧张状态) on the body produce aching shoulders and nervous feelings. Variety and movement keep you physically and mentally alive. The most interesting task can get boring if done for long periods of time, and the most comfortable chair isn’t comfortable if the worker must sit in it for hours.

Think at the end of the day

4.　　　　 . And if you are tired, is it because of the mental work you’ve done, or the way you have done it? Generally, if you feel extremely tired at the end of the day, it’s quite likely been an inefficient (效率低的) day.

5.　　　　 Then you can work with a new attitude the next day.

A. Think of a cat

B. Work less hard

C. Work in a comfortable position

D. This will help you form the habit of relaxing.

E. Make notes of what changes you need to make.

F. Ask yourself how tired you are at the end of the day.

G. The greater part of tiredness comes from mental attitudes.
