How's this for a coincidence (巧合)? Charles Darwin and Abraham Lincoln were born in the same year, on the same day: Feb. 12, 1809. Although people hardly think of them together, yet we want to say that they belong together. It's not just because they were both great men, and not because they happen to live at the same time. Rather, it's because the scientist and the politician each started a revolution that changed the world.

They were both revolutionaries in the sense that both men changed the realities when they were born. They seem and sound modern to us, because the world they left behind them is more or less the one we still live in. So, considering the joint greatness of their contributions and the coincidence of their birthdays — it is hard to wonder: who was the greatest man? It's an apple and an orange—or Superman vs. Santa—comparison. But if you limit the question to influence, very quickly the balance tips in Lincoln's favor.

As great as his book on evolution is, it does no harm to remember that Darwin hurried to publish The Origin of Species because he thought he was about to be scooped (抢先) by his fellow naturalist Alfred Russel Wallace. Lincoln, however, is unique. True, his election as the president did cause the recession (衰退) and the war, but that war seems certain to happen—not a question of if but when. Certainly we know what happened after he was murdered: Reconstruction was organized and then abandoned, leaving the issue of racial (种族的) equality unsolved for another century.

Surely we should not deny Darwin's accomplishment. But their same birthdays gave us a great opportunity to observe these men of their time.

Born in London in 1825, Thomas Henry Huxley was one of the greatest men of the nineteenth century. In 1846 Thomas Henry Huxley was appointed assistant doctor aboard H. M. S. Rattlesnake. The ship had been asked to survey areas of the Great Barrier Reef and the neighboring seas. This gave Thomas Henry Huxley an opportunity to study animal life and was the start of his biological career. The voyage lasted four years, during which time he gathered much information on plankton (浮游生物).

On his return from the voyage, Thomas Henry Huxley was made a member of the Royal Society in recognition of his scientific work. Although he continued to publish papers about plankton, his interest was turning towards vertebrate (有脊椎的) animals. For sometime Thomas Henry Huxley and his workmates had been discussing the possibility that animal species had evolved (进化), one from another. No satisfactory theories had been put forward, but in 1859 Darwin's Origin of Species appeared. Thomas Henry Huxley at once realized its importance and how the theory of natural selection provided "the working hypothesis (假说) we sought".

For the rest of his life Thomas Henry Huxley struggled to ensure the full recognition of Darwin's work. In 1863 Thomas Henry Huxley published Man's Place in Nature in which he compared man and great apes (猿). He clearly showed similarities.

Despite his many achievements, he was given no award by the British state until late in his life. From about 1870, Thomas Henry Huxley was too involved in other things to continue actual research. He had always been interested in education. He pioneered the teaching of biology and his method of selecting "type animals" is still followed today. He spent the last ten years of his life writing essays mainly on biology.

Have you ever seen a miracle happen?  Two winters ago, I did. It was 1 that day. The road was covered with snow.

I asked my mom if we could go to our neighbor's hill and take my dog, Buddy. She said, "Sure. 2 don't go any farther than that. " After a while, we walked over to another hill by a pond (池塘) not far away. Then suddenly I saw Buddy walk out onto the ice. I was 3 when he walked to the middle of the pond.

With Memorial Day and summer right around the corner, you're bound to feel a serious case of wanderlust coming on. Whatever you've got in mind, we've rounded up a selection of the world's most beautiful camping spots to get you started.

◆Yosemite National Park, California

Ninety-five percent of Yosemite National Park is set apart for wilderness, which means no cars, no buildings, and no electricity. Sleep under the stars and hike up to Glacier Point for a view of Yosemite Valley, Half Dome, and Yosemite Falls. Make sure you store your food properly though black bears are common!

◆Boya Lake Provincial Park, Canada

Boya Lake Provincial Park, known for the color and clarity of its lake, is a great place to enjoy any type of water recreation. The lake is also one of the few in the north that's warm enough for swimming. The area was carved out by glaciers, leaving many islands and lakes behind for modern campers to explore on the park's hiking trails.

◆Corcovado National Park, Costa Rica

Corcovado National Park is home to five percent of the world's biodiversity—National Geographic described it as the most "geographically intense" place in the world. Camping is a great option for a visit to Costa Rica: you'll be at the heart of the rainforest away from the country's touristy resorts.

◆Maasai Mara National Reserve, Kenya

If you've always dreamed of safaris, Maasai Mara is the place to go. The ideal time to visit this large game reserve is between July and October, when you can witness the annual migration of Thomson's gazelle, zebra, and wildebeest to and from the neighbouring Serengeti, in Tanzania. Camp on the banks of the Mara River and hang out with the local Maasai people, well-known for their distinctive customs and dress.

More than 30, 000 runners selected from 160, 000 applicants both in and out of China (take) part in this year's Beijing Marathon on Nov 3. (wear) colorful T-shirts and posing for photos, they gathered at Tian'anmen Square before taking their places at the starting line.

Nearly a decade ago, Chinese marathon(organizer) struggled to fill the starting blocks. Now, at big eventsthe Beijing Marathon, runners must win a lottery (enter).

This is part of the world's running boom (热潮). For millions of runners around the world, the real reason they head out to pound the roads until their legs hurt is more than weight (lost) or fitness.

Chasing records like the three-hour mark, for example, is important, but it's not people run mile after mile, up hills, in wind and rain, when they could just stay comfortable in their beds. Record times are merely the carrots they dangle (悬挂) in front of (they).

Last year, a runner in the United Kingdom trained with the goal of  (run) a marathon in less than three hours. In the end, he finished in three hours and two minutes. However, he was pleased afterward. "If I had done it, that would be it. " he told the Guardian. "Now I've still got my target, I can try again next year. "

running is hard and requires effort, it also brings joy. Think about children. When they are excited, they can't stop running back and forth, up and down.

American English began in the 17th century. At the beginning of the 17th century, the English language was brought to North America by colonists (殖民者) from England. They used the language spoken in England, that is, Elizabethan English, the language used by Shakespeare.

In order to find new resources in America, British colonists settled down there and from 1607 to 1732 set up thirteen colonies, including Virginia, North Carolina, New York, and New Jersey. In these thirteen areas, English was a common language used by all people. The first colonists established the English form in America.

As time went by, the English language gradually changed on both sides of the Atlantic. Foreigners longing for wealth set foot on the coastal area to trade. Americans borrowed many words from foreign languages and invented numerous new words to meet their commercial needs.

Following American Independence, famous people like Thomas Jefferson, the President, began to consider that the country should have a language of its own. Noah Webster compiled (编撰) three elementary books on English. Later, he expressed the idea that as an independent nation, America should have a system of its own in language as well as in government.

Since the rise of the United States to a position of world importance, American English has been developing and changing. There is no doubt that American English will enrich the English language greatly. With the rapid development of modern mass media and the common needs of economic, cultural and political exchanges, American English is more widely used in the world than British English.
