1. Penguins Mate for Life

During the mid-2000s, films like "Happy Feet" made penguins all the rage, and young lovers went around spreading the facts like "penguins mate for life." While the idea is sweet, it's not exactly true.

Penguins usually stick with their partners through the mating season, but when it's time to mate again, they choose whomever is convenient, not necessarily their old flame.

2. Vincent Van Gogh Cut Off His Entire Ear

This is not entirely true. It was not his entire ear - just the tip of the lobe(耳垂) - and some say he didn't even do it. Van Gogh lived with artist Paul Gauguin, who had quite a violent temper, and many believe Gauguin actually did the cutting.

Either way, Van Gogh did reportedly send the tip to a prostitute.

3. Napoleon Bonaparte was Short

Everyone knows Napoleon Bonaparte was a tiny man - after all, his nickname was "le Petit Corporal." His reputation for being short even inspired the phenomenon known as the "Napoleon complex."

In reality, Napoleon stood around 5 feet and 7 inches tall, which was very average back in the day. Many believe his nickname was meant as a term of endearment, not a reference to his height.

4. Ben Franklin Preferred a Turkey to a Bald Eagle

The bald eagle is certainly a well-known representation of America, but legend has it that if Ben Franklin had his way, a turkey would have been much better. In reality, Franklin wrote a letter to his daughter mocking the eagle symbol used in a seal(印章) by the Society of the Cincinnati, a private military group.

He said it looked like a turkey and may as well be one.

5. You Have Five Senses

If you remember learning about the senses in elementary school, you know humans possess five: sight, smell, hearing, touch, and taste. Most scientists agree, however, that you have more like 10-20 senses, including pain, hunger, thirst, temperature, and more.

6. George Washington had Wooden Teeth

George Washington is known for three things: being the first president, chopping down a cherry tree, and having wooden teeth. At least one of these is certainly not true. While Washington did have bad teeth, his dentures(假牙) were not wooden.

7. Einstein was a Bad Student

If you ever made bad grades and pulled the old "Albert Einstein used to make bad grades" card with your parents or teachers, you are lucky you got away with it. In reality, Einstein was at the top of his class and mastered calculus when he was barely a teenager.

The reputation he developed for being a bad student had more to do with his behavior. He liked to talk back to his teachers.

1.Which is the true fact according to the passage?

A. Penguins usually stick with their partners through their whole lives.

B. Franklin laughed at the eagle symbol used in a seal and said it looked like a turkey.

C. Napoleon was much shorter than average.

D. George Washington’s false teeth were made of wooden.

2.Why do most people hold the idea that Albert Einstein used to make bad grades?

A. Because he used to like to talk with his teachers.

B. Because he used to be criticized by his parents.

C. Because he used to be different from other students.

D. Because he used to behave badly and usually didn’t respect his teachers.

Teenagers are often a difficult group. With all those hormones(荷尔蒙) flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food are likely to be happier than other teens.

The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are.

Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food.

Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining(克制) from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too.
