How much do you know about Albert Einstein?

Albert Einstein, born on March 14, 1879 in Germany, was a great scientist in the world. He was strange because he hated haircuts and new clothes. He believed in peace. All his life, he hated war. However, his most famous idea, E = mc², helped create the world's most dangerous weapon (武器). Many people think he was the smartest person in the world. But Einstein said that he thought like a child with many questions and unusual ideas.

What did he like?

Einstein liked learning sailing(帆船运动). He sailed in small boats all his life.  Heonce joked, "Sailing is the sport that takes the least energy!”

When Einstein was a child, his mother made him take violin lessons. At first, he didn't like the violin. But then he learned to love music and became a good violinist.

Later, he said, “Love is the best teacher.”

Why is the sky blue?

In 1910, Einstein asked a question which many children often ask, “Why is the sky blue?”After his careful research, he answered the question like this: “It's because light is made up of many colors including blue. When light travels to Earth, gas particles(气体微粒) spread the blue light all over the sky.”His answer is true in physics.

    There is an elephant and a monkey. They're friends. But one day they want to know who is stronger （更强壮）. One of them says, "Who can get apples from the tree across the river, who is stronger."The monkey says, "I can't swim." The elephant says, "I can swim. Please sit on my back."Thus they go across the river. The apple tree is very high. The elephant can't reach the apples on the tree. The monkey climbs（爬）up the tree and gets many apples. Now they know they should help each other.

    Jane Austen(1775--1817), an English' novelist, started writing young and completed six novels in her life. Today Austen's books are more popular than ever. In the last 10 years, five of her six novels have been made into Hollywood films, while her books continue to be best-sellers.

    Richard Jenkyns, a professor of English at Oxford University, says that her novels are about marriage, friendships and the family, which are still with us today. "The stories are timeless," Jenkyns said.

    Pride and Prejudice(《傲慢与偏见》) (1813) is Austen's most famous work. It is a love story about Elizabeth Bennet and Mr. Darcy. At first, these two dislike each other. Elizabeth is pretty, smart and lively. She is proud because Darcy doesn't know about her family. Mr. Darcy is handsome, rich and has a better family background. So, he is proud as well. At the same time, Darcy holds a prejudice against the Bennet family. He has no understanding of why the family, especially its mother and daughters should try so hard to find wealthy and powerful husbands. He thinks they are vulgar. Anyway, Elizabeth and Darcy finally fall in love and become a romantic couple(夫妻) but their families' "don t want them to.

    In Pride and Prejudice, some of the main things that Jane Austen wants to teach people are as follows. Opposites can attract (吸引 ) each other. Lovers should not only make each other feel relaxed or comfortable, but also educate and improve each other.

    Austen is often called the greatest romantic writer, so it is surprising she remained unmarried. "Maybe she was too romantic, waiting for the perfect man," Jenkyns says.

There are various reasons why people travel. Some tourists go to see battlefields or other historic remains. Others are looking for culture, or simply want to have their pictures taken in front of famous places. Most European tourists are looking for a sunny beach to lie on. 

Northern Europeans are willing to pay a lot of money for the sun because they have so little of it. People of cities like London, Copenhagen and Amsterdam spend much of their winter in the dark because the days are so short, and much of the rest of the year in the rain. This is the reason why the Mediterranean (地中海) has always attracted them. Every summer many people travel to Mediterranean resorts (度假胜地) and beaches for their vacation. They all come for the same reason: the sun!

The huge crowds mean lots of money for the economy of Mediterranean countries. Italy's 30, 000 hotels are booked without a break every summer. And 13 million people camp on French beaches, parks and roadsides. About 37 million tourists visit there yearly, or one tourist for each person living in Spain. 

But there are signs that the area is getting more tourism than it can deal with. The Mediterranean is already one of the most polluted seas on earth. None of these, however, is ruining(毁掉) anyone's fun. Obviously, they don't go there for clean water. They allow traffic jams and seem to like crowded beaches. They don't even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as the sun shines, it's still better than sitting in the cold rain in Berlin, London, or Oslo.
