People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume(消費) is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think."
In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity(肥胖), a 25% increase in the risk for abnormal(非正常的) blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol(膽固醇).
All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It’s something that surprised even the researchers.
Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that."
In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.
小題1: What does the underlined word “innocuous” in the first paragraph probably mean?
A．popular.B．harmless.C．effective.D．risky.
小題2: According to the study, which of the following is true?
A．Only people who overdrink sodas have high risk for heart disease.
B．In the study, about one quarter of people have high blood level.
C．Both regular and diet sodas can probably increase the risk for heart disease.
D．Dr. Vasan is the leader of the American Heart Association.
小題3: What can be inferred from the passage above?
A．All the experts agree with the results of the study.
B．Sodas of any kind are certain to increase the risk for heart disease.
C．People have expected the results of the research.
D．More studies are needed to prove the results.
小題4:How does the writer present the passage?
A．By comparing opinions.B．By giving advice.
C．By showing facts.D．By discussing information.

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes--Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect (反射) on the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands--Hand injuries can happen because the hands are moved in the same way hundreds of times. If you use a keyboard for a long time, follow this rule: Stop sometimes and exercise your hands and fingers in different ways.
Your back--Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back and your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(調(diào)查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.
小題1:The author answers the question raised in the first paragraph with ________.
A．stories and explanationsB．examples and investigations
C．a(chǎn)n argument and evidenceD．facts and descriptions
小題2:Which of the following statement is true?
A．Being focused while eating is a good way to have a good figure.
B．Adults’ weight is not affected by their eating habits.
C．There exist many investigations into eating while reading.
D．This text must be found on a website.
小題3:What can be the best title of this passage? 
A．How Should You Lose Weight?
B．Should You Do Other Things While Eating?
C．Healthy and Unhealthy Eating Habits
D．TV and Eating
小題4:What will the author probably continue to write?
A．Express healthy eating ways.
B．Give more useful investigations into eating.
C．Describe the study about the old who watch less TV while eating.
D．Tell the proper ways to watch TV.

How often do you go on holiday? Going on holiday makes you feel good while you're there－you gain the health benefits for months, new research shows.
Jetting off to exotic destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their full holiday entitlement each year－as many as one in three don't－to get the benefits.
The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working. The average blood pressure of those on holiday dropped by 6% while the workers saw their blood pressure rise by 2% over the same period. The sleep quality of holiday-makers improved by 17% while that of the non-holidaymakers deteriorated by 14%.
The study also found the ability of vacationers to recover from stress—known as the stress-resilience test－improved by 29%. There was a 71% fall in stress resilience scores among workers. Test showed a fall in blood glucose levels, reducing the risk of diabetes, trimmer waistlines and enhanced mood and energy levels, with the effects sustained for at least 2 weeks after returning home.
The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK's largest healthcare charity.
小題1: The author intends to tell us that _____.

       positive through the cold season could be your best         against getting ill, new study findings suggest.
In an experiment that         healthy volunteers to a cold or flu virus, researchers found that people with a         sunny characteristic were less likely to         ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help         the common cold and other illnesses.
Researchers believe the reasons may be both objective as in happiness increasing immune(免疫的) function and subjective as in happy people being less         by a scratchy throat or runny nose. “People with a positive emotional style may have different immune         to the virus,” explained the lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “And when they do get a cold, they may         their illness as being less severe.”
Cohen and his colleagues had found in a         study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional tendency itself had the effect.
For the new study, the researchers had 193 healthy adults with complete standard measures of personality tendency, health-consciousness and emotional “style”. Those who         be happy, energetic and easy-going were judged as having a positive emotional style,         those who were often unhappy, tense and unfriendly had a negative style. The researchers gave them drops through their noses         either a cold virus or a particular flu virus. Over the next six days, the         reported on any aches, pains, sneezing they had, while the researchers collected         data, like daily mucus(黏液) production. Cohen and his colleagues found that based on objective measures of nasal woes(鼻部的不適), happy people were less likely to develop a cold.

Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.
Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.
1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(穩(wěn)定桿). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.
2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(護(hù)墊). Fit pads come in different sizes and attach to the helmet with Velcro.
3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.
4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.
5) Recheck the fit regularly.
You should replace the bicycle helmet:
If she has been in an accident with it.
If the buckle(金屬扣) breaks or if a piece breaks off.
If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.
If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.
小題1:Who is this passage mainly written for?
A．Children.B．Teachers.C．Parents.D．helmet producers.
小題2:What does the author mainly want to stress in the second paragraph?
A．The bike-related injury is a serious threat to the children.
B．The bicycle helmets must fit properly while the children are biking.
C．It’s necessary for the children to wear helmets while biking.
D．Many students suffer bike-related injuries every year.
小題3:If a girl finds a helmet a little bit big for her head, what should she do?
A．She must buy a smaller size.
B．She can use some fit pads.
C．She can put fingers on both temples inside the helmet.
D．She must make helmet slide from side to side.
小題4:Phil White, a father, found the buckle of his girl’s helmet broken, he can_______
A．buy a new bicycle helmet for her
B．mend the bicycle helmet himself
C．continue to use the bicycle helmet
D．throw away the broken buckle

WASHINGTON－School lunches have been called many things, but a group of retired military officers is giving them a new label: national security threat.
That's not a reference to the mystery meat served up in the cafeteria line either. The retired officers are saying that school lunches have helped make the nation's young people so fat that fewer of them can meet the military's physical fitness standards, and recruitment will be difficult.
A new report being released Tuesday says more than 9 million young adults, or 27 percent of all Americans ages 17 to 24, are too overweight to join the military. Now, the officers are advocating for passage of a wide­ranging nutrition bill that aims to make the nation's school lunches healthier.
The military group acknowledges that other things keep young adults out of the armed services, such as a criminal record or the lack of a high school diploma. But weight problems that have worsened over the past 15 years are now the leading medical reason that recruits are rejected.
Although all branches of the military now meet or exceed recruitment goals, retired Navy Rear Adm. James Barnett Jr., a member of the officers group, says the obesity trend could affect that.
“When over a quarter of young adults are too fat to fight, we need to take notice，” Barnett said. He noted that national security in the year 2030 is “absolutely dependent” on reversing child obesity rates.
This isn't the first time the military has gotten involved in the debate over school lunches. During World War Ⅱ， military leaders had the opposite problem, reporting that many recruits were rejected because of stunted growth and inadequate nutrition. After the war, military leaders pushed Congress to establish the national school lunch program so children would grow up healthier.
Today, the group is urging Congress to eliminate junk food and high­calorie beverages from schools, put more money into the school lunch program and develop new strategies that help children develop healthier habits.
小題1:What is the main problem of the lunches in schools according to the military officers?
A．The meat in the lunches is mysterious.
B．The lunches are too expensive.
C．The lunches contain too much fat.
D．There is inadequate nutrition in the lunches.
小題2:The underlined word “obesity” in Paragraph 5 means ________.
A．slow in mind B．state of being fat
C．quick in movementD．lack of confidence
小題3:Which of the following statements is NOT true?
A．The lunches in American schools are not very healthy.
B．During World War Ⅱ，many people could not join the army because of overweight.
C．According to the author , overweight was the key reason why many recruits were rejected.
D．By now, Congress hasn't eliminated junk food and high­calorie beverages from schools.
小題4:Which of the following is the best title for the article?
A．School lunches: a national security threat?
B．National security in danger ?
C．Retired officers tired of school lunches
D．The recruitment of 2030
