For anyone still doubting the belief that our emotions influence our physical health, a new study from New Zealand should be able to settle the matter. It reports that the physical wounds of healthy seniors healed more quickly if they wrote about their most upsetting experiences.

This confirms the results of a 2010 study, and extends those findings to cover older adults—a group that is likely to suffer wounds (as from surgery), and one with less access to other ways of lowering tension (such as exercise).

Reported in the journal Psychosomatic Medicine, a research team led by the University of Auckland’s Elizabeth Broadbent made a study featuring 50 healthy adults ranging in age from 64 to 97. They were asked to write for 20 minutes per day for three consecutive(连续的) days.

Half were asked to write about the most upsetting experience in their life, describing their deepest thoughts, feelings, and emotions about the events, ideally not previously shared with others. The others were asked to write about their daily activities without mentioning emotions, opinions or beliefs.

Two weeks after the third day of writing, all participants received a standard 4mm skin biopsy(皮下活体组织检查) on their inner arm. The very tiny wounds caused by the biopsy were photographed regularly over the following days to determine the rate at which they healed.

On the 11th day after the biopsy, the wounds completely healed on 76.2 percent of those who had done the expressive writing. That was true of only 42.1 percent of those who had written about everyday activities.

“The biological and psychological mechanisms(机体) behind this effect remain unclear,” the researchers wrote, noting that those who had done the expressive writing did not report lower stress levels or fewer depressive symptoms than the others in the control group. Even if they weren’t consciously aware of feeling more relaxed or positive, the expressive writing appeared to have caused some sort of bodily reaction—probably involving their immune systems—that hastened their recovery.

1.What was the difference between the two groups of participants in the study?

A. What they wrote.

B. Where they wrote.

C. When they wrote.

D. How often they wrote.

2.According to the text, the experiment lasted 　　　　 .

A. about three days 　　　　　　 B. about a month

C. about two weeks　　　　　　　　 D. about ten days

3.The underlined word “hastened” in the last paragraph is closest in meaning to 　　　　 .

A. speeded　　 B. showed　　 C. limited　　　　　　 D. ruined

4. What would be the best title of the text?

A. Sharing with others can reduce stress.

B. Skin biopsies are likely to cause wounds.

C. Expressive writing heals physical wounds.

D. Upsetting experiences influence our emotions.

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(讲究的) eaters.

Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies and always get the smaller bag of popcorn(爆米花).

According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

Nutritionists have gone back and forth（来来回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

1.Why do people eat too much junk food though it is bad for our health?

A. It’s delicious from chips to candy.

B. Because it’s available here and there.

C. It’s easily taken everywhere.

D. It’s easily bought in fast food restaurants.

2.Which of the following is TRUE according to the passage?

A. If people are watching a tragedy, they eat up to 29% more popcorn.

B. People are likely to eat more food when staying with friends.

C. Nutritionists have the same opinion about how much to eat in the morning.

D. People prefer to snack from a large bucket.

3.What will he or she do if he or she wants to lose weight?

A. To eat nothing in the morning.

B. To get up early and to go to bed late.

C. To eat breakfast and exercise.

D. To snack from a medium-size bucket.

A cellphone is one of the few things that we hold close to our faces all the time, and yet it could possibly explode - this is what made the recent Samsung’s Galaxy Note 7 smart-phone accidents so shocking.

According to technology news website The Verge, flawed（有瑕疵的）phone batteries might be to blame.

Even if you are not a science student, you probably know that it is common sense that the anode (the negative（负的）end of the battery) and the cathode (the positive end) should never touch. If they do, the battery will short-circuit（短路）, causing a powerful electrical reaction that can destroy the battery and cause a fire.

This is why all lithium-ion（锂离子）batteries - the kind that can be found in many of our devices like tablets and cameras - have a separator layer inside to stop the two ends from touching one another.

But somehow, the separators in some of the Samsung phones broke, causing explosions.

Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

The two “somehows” may sound random（随机的）and hard to explain. But they actually both come from the fact that phone producers have been pushing the limits of batteries to meet customers’ demand for a longer battery life.

According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers’ demand that their devices get thinner has also given producers little choice but to try to put more power into thinner batteries.

“The more energy you put into a box, the more dangerous it’s going to be,” Billy Wu, a lecturer at Imperial College London, told The Guardian.

A thinner battery also means producers have to use thinner material for separators, and thinner material has more chance of breaking.

1.A separator layer is put in lithium-ion batteries in order to ___________.

A. ensure a longer battery life

B. prevent a battery from short circuiting

C. connect the anode and the cathode

D. reduce a certain electrical reaction

2.What are the direct reasons for the Samsung phone explosions?

A. Short circuiting and overheating

B. Pushing the limits of batteries

C. Overcharging and thinner batteries

D. Automatic charging and broken separators

3.Lynden Archer’s comments indicate that ___________.

A. demands for thinner cellphones are unreasonable

B. lithium-ion batteries can’t hold much more power than that they do now

C. producers can use 10 percent of a lithium-ion battery

D. new material for batteries is needed to meet consumers’ demands

4.What is the writer’s main purpose of writing the article?

A. To describe problems facing cellphone producers

B. To explain the reasons for the Samsung phone explosions

C. To teach us common sense when it comes to batteries

D. To warn us about the dangers of lithium-ion batteries
