Below are some smart ways to stay healthy suggested by some American experts.

Drink More Coffee

When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”

Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.

“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”

Take a Walk for Your Memory

Aerobic (有氧运动的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (脑衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.

It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”

Early to Bed, Early to Eat

“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.

“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”

Use the 20-Second Rule

What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.

Imagine the Worst to Feel Better

Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.

1. According to Sanjiv Chopra, most people should not drink more than ______ cups of coffee a day.

A. two????????????? B. three????????????? C. four????????????? D. six

2.Which of the following may help people on a diet to improve their results?

A. Raising their heart rate.????????????? B. Taking a walk for their memory.

C. Eating at fixed times.????????????? D. Sleeping in every morning.

3.According to Shawn Achor, if people place their shoes and exercise clothes next to their bed at bedtime, they’re more likely to ______ the next morning.

A. do exercise????????????? ????????????? ????????????? B. set a goal?????????????

C. cut 20 seconds off????????????? D. sleep 20 minutes more

4. Why should people spend a little time imagining their life without good things?

A. To experience surprise.????????????? B. To feel better.?????????????

C. To consider their own blessings.????????????? D. To prepare for the worst.

Facebook means never having to say goodbye. The social media website has earned a reputation for reconnecting old friends. Last week, a guy whom I hadn’t seen since my bachelor party five years ago sent me a friend request. I accepted and waited for “Easy E” to send me a greeting of some kind. He had sought me out, after all.

I learned from his profile that he was in a relationship and had a son. However, I’m pretty sure we won’t ever write wall-to-wall, let alone e-mail each other. But he’ll remain a friend of online until one of us makes a point of removing the other from his official list.

My pool of friends consists of family members, college buddies, co-workers from past and present, and friends of friends. There are 35 in all. If I spent some time uploading old e-mail addresses, I’m confident that I could increase my friend count actually.

A person could make a mission out of reconnecting with childhood friends, former classmates, distant cousins, and those one would like to get to know better. And some people can even handle hundreds of on-screen relationships, keeping up with the daily happenings of their small army of companions. After all, there are worse fates than having too many friends.

Thanks to e-mail, the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with e-mail, people will lose touch if one or both parties stop writing back. That’s normal. People move from school to school, job to job, city to city. You never have to feel guilty for breaking away.

Every day, the masterminds of Web 2.0 find new ways of making human communication easier. However, convenience can be a walking stick. Some things shouldn’t be simplified. When it comes to friendship, there can be no shortcuts.

1.According to Paragraph 1, the website is famous because       .

A.it has an interesting name of “Facebook”

B.it can send people a greeting of some kind

C.it helps people get in touch with old friends

D.it reminds people of events in the past

2.From the second paragraph we can learn that the writer       .

A.would write to the friend quite often

B.did get some information about the friend

C.asked the friend to e-mail him

D.would keep in touch with the friend forever

3.Which of the following statements is NOT true?

A.The author communicates with all the 35 friends by e-mails.

B.There are 35 people in the author’s list of friends right now.

C.The list of 35 friends doesn’t include the old e-mail addresses.

D.It is not difficult for the author to increase his friend count.

4.What does the writer mean by saying “However, convenience can be a walking stick”?

A.The masterminds of Web 2.0 also sell walking sticks online.

B.Taking a walking stick is a new way of making friends online.

C.Convenience is dangerous for human communication.

D.Convenience is not really good for human communication.

Scholarship Application Tips in 2013 for college students

·Before you apply

1. Work hard to get good grades. Don’t sweat about one bad grade, but always strive(力求)to do your best.

2. Get involved, and stay involved, in extracurricular(课外的)activities. Sports, clubs, drama, bands and orchestras-these often count toward a student’s overall scholarship application evaluation. The same goes for paid (or unpaid) work experience.

3. Begin your scholarship research early-by your sophomore(大学二年级)or junior year of high school, if possible. Make special note of application deadlines, as they can vary from late summer to late spring.

4. Apply for as many scholarships as you are eligible(符合条件的)for-several smaller scholarships can add up to a lot of money.

·During the application process

1. Read the supplementary materials that come with scholarship application forms to better understand the program’s focus (community service, subject interest). Try to answer the questions with the focus area in mind.

2. Answer questions as they are asked. Don’t got off topic.

3. If there is a financial component to the application, make sure you get accurate and complete information from all appropriate sources to ensure your eligibility.

4. Take your time. Write down everything you can think of for each question, then set the application aside for a day so you can look everything over again before you send it off.

5. Don’t wait until the last minute to complete your application, especially if you are applying online. Computer systems can get clogged(阻塞的)with the large volume of applicants hoping to submit their qualifications during the last few days and hours before a deadline.

6. If a third party has to complete part of your application, such as providing a letter of recommendation, make sure you ask them early on and remind them as often as necessary to ensure they provide you with the necessary materials.

7. Last but not least, review your application with your parents to make sure you haven’t left out any important details.

Once there was a man who lied to eat mangoes. One day he decided to get the sweetest mango from the very top of the tree. Mangoes which are exposed to the sun the most are the sweetest.

So he climbed up to the top, where the branches were thin. He managed to pick up a few sweet reddish fruits, but, in an attempt to climb down, he slipped and started falling towards the ground. Fortunately, he caught the branch as he was falling and remained helplessly hanging on the tree. Then he started to call nearby villagers for help. They immediately came with a ladder and sticks, but could do little to help him.

Then after some time one calm and thoughtful person arrived - a well-known sage who lived in a simple hut nearby. People were very curious to see what he would do, as he was famous in solving many people’s problems in the area and sometimes very complicated ones.

He was silent for a minute and then picked up a stone and threw it at the hanging man.

That’s what everybody wanted - that he came down. But how? Now everybody was tense, as to what would happen next! Some wanted to chastise the sage, but they didn’t. The sage picked another stone and threw it again at the man, even more forcefully. Now the man on the tree was enraged and developed a great determination to come down and take revenge.(复仇)

He then used all his skill and strength and somehow reached the branches which were safe to start going down. And he made it! Everybody was amazed.
