Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa— the main ingredient in chocolate— and found that it does seem to strengthen the heart. Studies have shown heart benefits from increased blood flow. These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)。
Better blood pressure
If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼). _______________________________________________________________________________.
Better for your skin
German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister(润滑的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
Brain gains.
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving skills by increasing blood flow to the brain.

Short and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis, Cricket—anything with a round ball, I was useless." he says now with a laugh. But back then he was the object of jokes in school gym classes in England's rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind on building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway's school of Adventure in Scotland, where he learned about the older man's cold-water exploits（成就）. Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.
Journeys to the Pole aren't the usual holidays for British country boys, and many people dismissed his dream as fantasy." John Ridgway was one of the few who didn't say, 'You are completely crazy,' " Saunders says.
In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter（遭遇）with a polar bear and pushed his body to the limit.
Saunders has since become the youngest person to ski alone to the North Pole, and he's skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.

There is no doubt that for a long time college education has been accepted. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become “better” people, and learn to be more responsible citizens than those who don’t go.
But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don’t fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere(妨碍；干扰) with each other’s experiments and write false letters of recommendation in the fierce competition so as to get admitted into graduate schools. Others find no stimulation (激励) in their studies, and consequently have to drop out, which is often encouraged by college administrators.
Some observers say the fault is with the young people themselves--they are spoiled and they are expecting too much. But that’s a condemnation(指责) of the students as a whole, and doesn’t explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy can’t absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds,either.
9. What’s the main idea of the first paragraph, ___________________.

A．people have great expectations for college education.

B．people still have a low opinion of college education.

C．the author thinks youngsters should all go to college.

10. The reason why more young people drop out of college is that _________.

A．they can start selling shoes and driving taxis.

D．college administrators force them to do so.

11. Who contributes to campus unhappiness?

A．young students who are all spoiled and expecting too much.

B．our society that can’t offer enough jobs to college graduates.

C．young people as well as our society are to blame for all this.

D．our society that has not enough jobs for high school graduates.

Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some avoid doctors because of the high cost of medical care, especially if they lack health insurance. Or they may stay because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctor can also be a deadly game.
Every day, more than six million Americans turn to the Internet for medical answers – most of them aren’t nearly skeptical enough of what they find. A 2012 survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn’t. Look up “headache”, and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2015 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.
The problem is that most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative(权威的), so it’d hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.

Having a happier life is something we all always struggle for. One of the key foundations ofthat is to be consistent in doing things that bring happiness.    16    Consider these 4 habits:
1. Laugh in the middle of a busy day.
It’s 3 pm on a Sunday afternoon and you’re desperate to leave, for school. On top of the homework, you’re running close to super important deadline.    17    Just take a moment to laugh. You should laugh more often, especially on a busy day.
2. Do not compare yourself to others.
Measure your own successes based on your progress and only yours.    18    No one is better than any one else.
3. Find time to work out regularly and eat well.
Exercise can produce tons of feel-good hormones（荷尔蒙）.    19    Feeding your body with whole and nutritious foods, on the other hand, can positively affect your body in both short and long term. Find time to schedule in a workout even if it’s only thirty minutes and do something you love. Eat well because foods can help you stay focused and more energized, and happier as a whole.
4. End each day with gratitude.
    20    It might be something as small as a child’s laugh or something as huge as a praise from the headmaster. Whatever it is, be grateful for that day because it will never come again.
