While retiring ahead of time may be easier on the body, a new set of research has found that it may not be so beneficial to the mind. The study, carried out at Binghamton University, finds that an early retirement can speed up the usual rate of cognitive (认知的)decrease among the elderly.
The research team studied China's new rural pension (退休金)system, as well as China's most recent Retirement Longitudinal Survey ( CHARLS), in order to look into the effects of early retirement and pension benefits on individual cognition among adults over the age of 60. After going over all of the data, the research team noted a clear direction: people receiving pension benefits were experiencing much more rapid mental decline (智力下降)than those still on the workforce. Surprisingly, women seemed to experience even sharper mental decline after retiring early. Overall, the results support the view that decreased mental activity speeds up cognitive decline.
Nikolov, the lead researcher, had actually carried out former studies that found retirement led to a number of physical health benefits for retirees, such as improved sleep patterns, less stress, and reduced alcohol consumption. However, retirement also usually goes with a decline in social activities and less communication with people, which has also been linked to cognitive decline.
“For cognition among the elderly, it looks like the bad effect on social connection is more than the good effect of the program on fitness and sleep,” Nikolov says. “ Or social connection may simply be the single most powerful factor for cognitive performance in old age.”
The research team are hopeful that their findings will be considered by older adults when thinking about retirement, but perhaps more importantly, they hope that policy makers in developing countries take note while drawing up new pension plans. They suggest building social get-togethers and work shops for recent retirees to help cut down the decline in social communication and creative thinking that often comes along with retirement.
1.Which of the following best describes retiring ahead of time for the mind?
A.Useless. B.Beneficial. C.Damaging. D.Improving.
2.Who mentally suffered most according to the research?
A.Men retiring on former plan. B.Women over the age of 60.
C.Men retiring ahead of time. D.Women retiring early.
3.What will retirement bring to the elderly?
A.Shorter sleep time. B.Fewer social activities.
C.More financial stress. D.Less time with family members.
4.What can we learn about the research team's suggestion?
A.The government should make new policy.
B.People should build more shops for the elderly.
C.The retirement in developing countries should be common.
D.The newly retired people should communicate more.

We all know that exercise is good for our health. To stay healthy, doctors suggest doing 150 minutes of moderate（适度的）exercise every week. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.1. Compared to non-runners, runners show 30% lower risk of death," researchers said.
2.Here are four commonly shared ideas among fitness experts to reduce the risk of injuries for people new to running.
• Take it easy.3. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance or speed. Muscles（肌肉）and joints（关节）need time to recover.
• Get good running shoes. There is no single best shoe for every runner. You should find the shoes that offer the best fit for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.
•4.Take some time after each run to write down notes about what you did and how you felt. Look for patterns, things that happen over and over again.
• Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some forms of cross training to improve muscle balance and to help you stay injury-free. For example, swimming, cycling and yoga are good exercises to combine with running.5.
A.Take good notes.
B.Running also may help you live longer.
C.Running takes a lot of time.
D.Running may be good exercise, but it can be difficult on the body.
E.As we all know, doing sports helps us teamwork.
F.These exercises are easier on the body.
G.Do not run too much, too soon or too fast.

There has been a debate for some time that food can be addictive (上瘾的). Most researchers may not agree with it. But this spring, experts on health discovered that for some, obesity (肥胖症) is “an addiction like smoking.” One month earlier, a lecture showed that food and drug addictions have much in common, especially in the way that both damage the parts of the brain involved in pleasure and self-control.
Earlier this year, some scientists carried out brain-scan studies on children who looked at pictures of chocolate milkshakes (奶昔) and later ate the milkshakes. Children who are regular ice-cream eaters may require more and more ice cream for the reward centers (奖励中枢) of their brains to tell that they are satisfied.
However, meditation and exercise can help the brain to overcome food addiction. Food addicts (嗜食者) should look for alternatives that still give pleasure — a fruit smoothie, for example, instead of ice cream.
Food addiction seems to be linked to the types of foods we’re eating. It’s easier for human body to deal with foods found in nature, not processed (加工的) foods. When a highly processed food is eaten, the body may go uncontrollable. Potatoes are not addictive, but when they are processed into chips, what happens? Products like chips are described as super-delicious foods. They were the right combination of something salty, sweet and fatty along with “mouth-feel.”
1.Why may regular ice-cream eaters need more ice-cream over time?
A.To stop being addicted to it. B.To meet the needs of the brain.
C.To control the centre of the brain. D.To satisfy the needs of the stomach.
2.What does the underlined word“alternatives”in paragraph 3 mean?
A.Replacements. B.Fruits. C.Methods. D.Drinks.
3.What can we know from the last paragraph?
A.Processed foods are healthier. B.People are born with food addiction.
C.Processed foods usually have a better taste. D.Processed foods are usually more expensive.

Crossing your legs is an extremely common habit; most people don’t even notice that they’re doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won’t feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long term health problems. So, panning to sit for a long period of time? Don’t keep your legs crossed.
Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis of some of the muscles in your foot and leg, preventing you from being able to raise your ankle. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
1.What can we learn about crossing one’s legs?
A.It is a very bad social habit. B.It is usually practiced by design.
C.It can make others feel uncomfortable. D.It has a negative effect on people’s heath.
2.We may conclude from the study that sitting with your legs crossed can ________.
A.improve the function of legs B.help your blood resist gravity
C.effect your blood pressure D.cause health problems instantly
3.According to Richard Graves, repeatedly crossing your legs may ________.
A.paralyze all of your muscles B.preventing you from standing up
C.damage your nerve in the leg in the end D.reduce the pressure on the major nerve
4.What is the main purpose of the text?
A.To blame a bad habit. B.To provide suggestions.
C.To introduce research methods. D.To show effects of an experiment.

SWEET LOVE
Many scientists believe our love of sugar may actually be an addiction. 1.. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.
“It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. 2.. Why? “Sugar, we believe, is one of the reasons, if not the major reason,” says Johnson.
Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. 3..
So what is the solution? It’s obvious that we need to eat less sugar. 4.. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat. So while the foods appear to be healthier, large amounts of sugar are often added.
5.. Many schools are replacing sugary desserts with healthier options, like fruit. Other schools are trying to encourage exercise by building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.
A.It’s not surprising that a cupcake contains a lot of sugar
B.So the very thing that once saved us may now be killing us
C.The trouble is, in today’s world, that it’s extremely difficult to avoid
D.But some people are fighting back against sugar and trying to create a healthier environment
E.One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes
F.If you have high blood pressure, your heart needs to work harder to pump blood around your body
G.When we eat or drink sugary foods, the sugar enters our blood and affects the parts of our brain that make us feel good

Tips for Cooking on a Tight Schedule
From my experience, there are three main reasons why people don't cook more often：ability, money, and time. 1.Money is a topic I'll save for another day. So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen. Here are three tips for great cooking on a tight schedule：
1. Think ahead. The moments when I think cooking is a pain are when I'm already hungry and there's nothing ready to eat. So think ahead of the coming week. When will you have time to cook? Do you have the right materials already? 2.
2. Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread? 3. It takes around the same amount of time to make more of something. So save yourself the effort for a future meal.
3. 4.This may surprise you, but one of the best tools for making cooking worth your time is experimentation. It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.
Hopefully that gives you a good start. 5.And don't let a busy schedule discourage you from making some great changes in the way you eat and live!
A.Try new things.
B.Ability is easily improved.
C.Make three or four instead.
D.Understand your food better.
E.Cooking is a burden for many people.
F.Let cooking and living simply be a joy rather than a burden.
G.A little time planning ahead can save a lot of work later on.
