A report says older adults who test their minds with increasingly difficult projects have better mental ability than those who do less demanding activities.
To keep our brains sharp as we age, we are often told to keep our minds active. As the old saying goes, “Use it or lose it.” But, there is very little scientific evidence to support than.
Denise Park is head of the university’s Center for ? Vital Longevity. She designed a study in which she and her tern placed 221 healthy aging and older adults into one of three groups.
“We asked people to learn new things, like quilting or photography. We asked other people to just do fun things like being in a social group function but were not likely to have a very large effect.”
The subjects took part in their assigned activities for 15 hours a week over three months. At the end of that time, the researchers found that the adults who learned new skills, such as digital photography, showed the greatest improvements on memory tests.
No improvements were seen in the results of those in the social group that did activities together like going on field trips. There were also no improvements among the third group that listened to classical music or did crossword puzzles.
Denise Park believes one reason for improved memory in the active learning group is that its members were being pushed to learn new skills. The other groups took part in what she call receptive activities. Learning new skills may not cure age-related mental decline. But, Ms. Park thinks being mentally active slows down the process.
Denise Park says the latest information shows that the improvements lasted for at least a year. She and her team plan to do longer follow-up studies with all three groups. She also is interested in learning whether taking part in demanding mental activities delays the development of conditions like Alzheimer’s disease.
1.What may the social group be asked to do?
A. Learn to take photos.
B. Listen to music at home.
C. Go hiking together.
D. Do the dishes.
2.What did Denise Park and her team find?
A. Doing more exercise can help slow down our age-related mental decline.
B. Having a relaxing life is beneficial to keeping our minds sharp.
C. Keeping our minds active is associated with our health.
D. Learning new skills may help to keep our minds active.
3.If you want to keep your brain sharp you could_______.
A. go swimming with your friends.
B. play chess with your family.
C. learn how to repair the computer.
D. do crossword puzzles online
4.The text is likely to be selected from a book of______.
A. medicine B. education
C. aging D. science

Imagine you’ve finally landed a job of your dreams in another city. It’s everything you’d hoped for, but there’s only one problem — housing costs in the area are so high that you’re forced to live in a parking lot.
While this sounds like an impossible situation, this predicament is a reality for one man.
Brandon, 25, is a software engineer for Google at its San Francisco, California campus.
“I realized I was paying too large an amount of money for the apartment I was staying in, and I was almost never home,” he told Business Insider. “It’s really hard to justify throwing that money away. You’re not putting money into anything and you are not building it up for a future.”
Since scoring his job in May 2015 following a successful internship, he’s been living in a truck on a parking lot a short distance from his workplace.
The tech worker makes up for the lack of facilities by eating, using the bathroom and showering at work, also charging his phone and computer there.
San Francisco is home to the most expensive rental market in the US, with the average rental for a one-bedroom apartment coming to $3,590 (24,900 yuan) a month, according to property site Zumper.
And while some may not be able to handle giving up life’s luxuries just to put aside some cash, Brandon estimates that he’s saved almost $28,000 since he moved in just over 18 months ago.
“Not only do I get to invest all of that redirected rent money, but I get to invest all the money I’m not spending on furniture, facilities and buying food,” Brandon wrote on his blog.
1.Which of the following can replace the underlined word “predicament” in Paragraph 2？
A. possibility B. disappointment C. dilemma D. mess
2.Why does Brandon prefer to live in a truck on a parking lot?
A. Because he has no time to go back to an apartment.
B. Because the rent is too high and he thinks it isn’t worthwhile
C. Because his workplace provides him with what he needs
D. Because he wants to save money for an apartment of his own.
3.What does Brandon think of his choice?
A. Difficult. B. Embarrassing. C. Painful. D. Wise.

While being lost in the woods can be a frightening experience, surviving alone in the wild is generally a matter of common sense, patience, and wisely using the gifts that nature provides.1..
Do your research first. Don't just trek off into the wilderness; get a solid understanding of your surroundings first. Studying a map of the area where you're going -- and making sure to bring it with you -- will increase your chances of not getting lost tremendously. Educate yourself about the flora and fauna of the area you are exploring. 2..
3.. A cell phone with a spare battery or a portable CB radio can be your best, quickest means of rescue if you are truly lost or injured. A cell signal may only be obtainable only from a hill or tree, but is better than nothing. Serious hikers may even consider investing in a personal locator beacon such as the SPOT Messenger for extended, precarious, or very remote, treks.
Don't panic if you’re lost. Panic is more dangerous than almost anything else, because it interferes with the operation of your single best, most useful and versatile survival tool: your mind. The moment you realize that you are lost, before you do anything else, stop.4.. Before you act, follow the idea of STOP: S = sit down T = think O = observe your surroundings P = prepare for survival by gathering materials.
Signal your location. Make noise by whistling, shouting, singing, or banging rocks together. 5. . If you're in a mountain meadow, make three piles of dark leaves or branches in a triangle. In sandy areas, make a large triangle in the sand. Three of anything in the wilderness is a standard distress signal.
A. Bring a means of communication.
B. If you can, mark your location in such a way that it's visible from the air.
C. Knowledge of the local plants and animals can save your life
D. If you want to know how to survive in the woods, just follow these steps.
E. Starvation won't be a big problem.
F. Take a deep breath and stay calm.
G. Having strength in numbers will help you survive.
