For decades, doctors have warned patients that too much salt can be bad for the heart. Heat attack has long been considered a grown-up problem, but a new research suggests that salt is starting to affect children. Eating too much salty food when you're young can lead to health problems later.
Salt is made up of two elements: sodium and chlorine. Dietary guidelines recommend that adults and kids aged 9 — 13 shouldn't consume more than about a teaspoon of salt daily. The average American eats twice this amount. This worries doctors because too much sodium results in the body producing more blood. To pump the extra blood, the heart has to work harder. This causes a rise in blood pressure a measurement of how stressed the heart is. High blood pressure often leads to heart disease.
A kid with high blood pressure is more likely to become a grown-up with high blood pressure. Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. Drinking fewer fizzy drinks makes kids less likely to gain weight, become obese and develop high blood pressure.
Salt can affect more than just your heart and weight. A recent study found that a growing number of kids in the US are suffering from kidney stones. This painful condition usually affects people aged over 40. Now, kids as young as five are getting it.
Cutting down on salt can be hard, but you can retrain yourself to prefer less salty food. The best way to reduce the amount of sodium you eat is to make changes gradually. Start by adding half as much salt to your dinner as you normally do. Switch to fresh foods instead of canned and bottled versions. And go easy on the condiments (调味品). You might also want to start reading nutrition labels. You may be surprised to learn that there are 1,150 mg of sodium in a double cheeseburger, and over 2 ,000 mg in many frozen meals.
1.What is the author's major concern?
A.Children eat too much salty food. B.Many adults suffer from heart attack.
C.Americans consume too much salt. D.Heart attack is now a youth problem.
2.What does the author refer to as the cause of childhood obesity?
A.Eating more salty food. B.Lack of physical exercise.
C.Drinking many sugary soft drinks. D.Eating the same food as the adults.
3.What is another disease tending to be younger according to Paragraph 4?
A.Obesity. B.Kidney stone.
C.Blood disease. D.Heart attack.
4.What is Paragraph 5 mainly about?
A.The laws of health. B.How to cut down on salt.
C.Healthy diet. D.The amount of salt we need.

Friendly doctors are“bad for their patients’health”，researchers have warned as a new study revealed two thirds of young doctors struggle to be truthful with patients they like．
Blurring(使…模糊)the lines between social and professional relationships can affect the level of care offered and prevent patients from being honest about important side effects．
“Doctors should avoid adding patients as friends on Facebook，they should not hug or allow patients to call them by their first names”．regulators have warned．“Those who break the boundaries will face some punishment．”
It comes as a survey of 338 oncologists(肿瘤科医生)under the age of 40，found 59 per cent said they found it difficult to tell the truth to those patients they liked．Sixty per cent of respondents said if doctors felt too close to their patients，it could prevent them from making objective decisions about a person’s care．
Lesley Fallowfield，of Brighton and Sussex Medical Schoo1．said：“Oncology is a profession that can be enormously rewarding but is filled with many challenges．Young oncologists have to master dealing with anxious patients who are facing a life-threatening disease；conveying the true prognosis(预后)；discussing the complexity of modern treatments；and explaining the unavailability of some drugs，the side-effects of treatment，and likely treatment aims．”
But she said，“Those doctors who have entered the profession in the age of the ‘Internet world’are more likely to fall victim to blurring the professional boundaries with patients．
She said：“The difficulty，if you hug and kiss patients，if you allow them to call you by your first name，is that quickly the relationship can become confused as a social one rather than a professional one．Doctors become confused，‘I really like this person，how can I bear to tell them that they’re going to die?’They find it more difficult to be objective．”
1.Why are ffiendl3，doctors bad for their patients’health?
A．They don’t like to cheat patients．
B．They are not good at treating patients．
C．They find it not easier to be objective to the patients．
D．They seldom blur the relationship with patients.
2.What should doctors do according to the regulations?
A．Add patients as friends on Facebook．
B．Have close connection with patients in life．
C．Always be cold to patients．
D．Keep a proper distance to patients．
3.Which opinion will Lesley Fallowfield agree with?
A．Oncology is a rewarding profession without challenges．
B．The Internet makes it easier for young doctors to break the boundaries．
C．It’s not the duty of doctors to deal with patients’anxiety．
D．Becoming friends with patients will help them recover soon．
4.Young oncologists will face the following challenges except_____________．
A．dealing with a lot of life-threatening diseases
B．discussing difficulties of treatment with patients
C．explaining the reason for the lack of some medicine
D．informing patients of the possible results of the treatment

It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.
According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract（呼吸道）, leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.
However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”
In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.
Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”
Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.
1. What can be the best title of the passage?
A. The mystery that has puzzled doctors for decades. B. New ways to prevent and treat flu.
C. A discovery of how flu strikes in Winter. D. Ways found to prevent flu.
2. Which of the following statements is NOT true?
A. Doctors have been trying hard to discover why flu strikes in winter.
B. In the past, scientists didn’t know how flu spreads.
C. It is possible that flu virus will no longer threaten humans in winter.
D. People get affected by flu because they spend much more time inside in winter.
3. Where should you insert the following paragraph into the passage?
Duane Alexander, the director of NICHD, said: “The study results open new avenues of research for thwarting (使…受挫)winter flu outbreaks.”
A. Between Paragraphs 1 and 2. B. Between Paragraphs 3 and 4.
C. Between Paragraphs 4 and 5. D. Between the last two paragraphs.
4.In what process or order does flu occur?
a. The virus infects cells b. The influenza virus was born
c. The butter-like material melts d. The virus hits respiratory tract
e. The virus coats itself in butter-like shield f. The virus is free
A. a, c, d, e, b, f . B. c, f, d, b, e, a. C. b, e, d, c, f, a. D. d, b, e, c, f, a.

In 1693 the philosopher John Locke warned that children should not be given too much “unhealthy fruit” to eat. Three centuries later, misguided ideas about child-raising are still popular. Many parents fear that their children will die unless ceaselessly watched. In America the law can be equally paranoid (偏执的). In South Carolina this month Debra Harrell was jailed for letting her 9-year-old daughter play in a park unsupervised (无人监督的).
Her severe punishment reflects the rich world’s worry about parenting. By most objective measures, modern parents are far more conscientious (认真的) than previous generations. Dads are more hands-on than their fathers were, and working mothers spend more time nurturing their children than the housewives of the 1960s did. However, there are two problems in this picture, connected to class. One is at the lower end. Even if poor parents spend more time with their children than they once did, they spend less than rich parents do. America is a laggard here: its government spends abundantly on school-age kids but much less than other rich countries on the first two or three years of life. If America did more to help poor parents with young children, it would have huge returns.
The second one, occurs at the other end of the income scale, and may even apply to otherwise rational (理性的) Economist readers: well-educated, rich parents try to do too much. Safety is part of it—they fear that if they are not constantly watching their children may break their necks, which is the least rational. Despite the impression you get from watching crime dramas, children in rich countries are safe, so long as they look both ways before crossing the road. The other popular parental fear—that your children might not get into an Ivy League college—is more rational. Academic success matters more than ever before. But beyond a certain point, parenting makes less difference than many parents imagine. Studies in Minnesota and Sweden, for example, found that identical twins grew up equally intelligent whether they were raised together or apart. A study in Colorado found that children that adopted and raised by brainy parents ended up no brainier than those adopted by average parents.
This doesn’t mean that parenting is irrelevant. The families who adopt children are carefully screened, so they tend to be warm, capable and middle-class. But the twin and adoption studies indicate that any child given a loving home and adequate stimulation is likely to fulfill her potential. Put another way, better-off parents can afford to relax a bit. And if you are less stressed, your children will appreciate it, even if you still make them eat their fruit and vegetables.

Study Links Video Game Use to Problems in School
A new study warns that too much time spent playing computer games could affect a child’s performance at school. 1. They show that too many hours spent playing games can reduce students changes of success in school.
More than 600 teenagers between the ages of 14 and 16 took part in research project.2. It is said to be the first ever long-term study of information technology on school test results in Northern Ireland.
The study found that teenagers who played computer games less than once a week were more successful in school than those who played them twice a day or more. 41% of the students who used gaming devices two or more times a day received passing grades on school exams.3..
The study found that social media use did not affect school performance. Celine McStravick is the director of the National Children’s Bureau Northern Ireland (NCBNI). She says “4.— I think that’s more because social media is part of every child’s life. It’s the way they communicate. It’s the way they keep in touch with their friends.”
Many parents say their children are becoming increasingly dependent on computer games. Some have compared gaming to a drug addiction.5. It suggested that computer games can cause children to stay awake late at night. Less sleep makes children tired and unable to pay attention in school the next day.
A. However, the study did not explore addiction.
B. The new games are much different from older ones.
C. The study showed no connection between social media and test results.
D. It took place over a period of three years from 2013 to 2015.
E. Thai compared with 77% of those who rarely played the games.
F. Drug addiction does great harm to their health and performance at school.
G. Britain’s National Children’s Bureau Northern Ireland reported the results of the study.
