3 . In the mid-1980s, a study compared mtDNA from people around the world. It found that people of African descent (后裔) had twice as many genetic differences from each other than as did others. Because mutations (基因突变) seem to occur at a steady rate over time, scientists were able to conclude that modern humans must have lived in Africa at least twice as long as anywhere else. They now calculate that all living humans descend from a single woman who lived roughly 150,000 years ago in Africa, “Eve”. If geneticists are right, all of humanity is linked to Eve through an unbroken chain of mothers. This Eve was soon joined by “Y-Chromosome (染色体) Adam”, the genetic father of us all, also from Africa. DNA studies have confirmed that all the people on Earth, with all their shapes and colors, can trace their ancestry to ancient Africans.
What seems certain is that at a remarkably recent date—probably between 50,000 and 70,000 years ago—one small group of people, the ancestors of modern humans outside of Africa, left Africa for western Asia, either by migrating around the northern end of the Red Sea or across its narrow southern opening.
Once in Asia, genetic evidence suggests, the population split. One group stopped temporarily in the Middle East, while the other commenced a journey which would last tens of thousands of years. Moving a little further with each new generation, they followed the coast around the Arabian Peninsula, India, and Southeast Asia, all the way to Australia. ''The movement was probably unnoticeable,'' says Spencer Wells. ''It was less of a journey and probably more like walking a little farther down the beach to get away from the crowd.''
Although archaeological evidence of this 13,000-kilometer (8,000-mile) migration from Africa to Australia has almost completely disappeared, genetic traces of the group that made the trip do exist. They have been found in the DNA of native peoples in the Andaman Islands near Myanmar, in Malaysia, and in Papua New Guinea, and in the DNA of nearly all Australian aborigines (土著). Modern discoveries of 45,000-year-old bodies in Australia, buried at a site called Lake Mungo, provide some physical evidence for the theories as well.
People in the rest of Asia and Europe share different but equally ancient mtDNA and mutations. The mutations which they possess show that most are descendants of the group that stayed in the Middle East for thousands of years before moving on. Perhaps about 40,000 years ago, modern humans first advanced into Europe.

4 . When you visit Kinderdijk, one of the most visited villages in the Netherlands, you step right into the middle of Dutch history.
Kinderdijk lies in the Alblasserwaard, where the Lek and Noord rivers meet together. Much of the village is near or even below sea level. Although there are canals and dykes (堤坝), the lowlands of the village are still at risk of flooding (洪灾). Among the most deadly floods was Saint Elisabeth’s flood in 1421, which killed thousands after the dykes broke in several places. To deal with this kind of problem, the Kinderdijk windmills (风车) were built around 1740 to move water from the lower areas to higher ground and into the river.
Nineteen of the 20 Kinderdijk windmills remain and were named a UNESCO World Heritage (遗产) Site in 1997. Of the 19 windmills, 16 still have millers who live inside and control the huge sails (翼板) in the wind. These windmills continue to help manage the Netherlands ongoing fight to stay above water.
For tourists, boat tours are offered along the canals and walkways lead from the visitor center to the windmills. Two windmills serve as museums, filled with old millers’ items and photos. You can climb up inside to see how the windmills work. The windmills also are working, so be prepared to feel the whole building shake when the sails turn in the wind.
Each year, about 500,000 people visit the Kinderdijk windmills and the buildings have become a must-see on any trip to the Netherlands. There are some windmills north of Amsterdam that “were built for tourists, but we’re a historical site where tourists come, so it’s the other way around,” says Kinderdijk communications manager Peter Paul Klapwijk. “Tourism is a good way to support our site.”

8 . World War II began when the UK and France declared war on Germany, after German troops led by Adolf Hitler had invaded Poland on 1 September 1939 to claim land there as their own. Hitler had already invaded Austria and Czechoslovakia, so the war began over his plan to take more land for Germany.
The Siege of Leningrad is a famous event during World War II. For 900 days—from 8 September 1941 to 27 January 1944—the city of Leningrad in Russia was surrounded by German troops. That meant everyone inside the city had to stay there, and that there wasn't any way for food or other sources like medicine to get in. Many hundreds of thousands of people died during this time because there wasn't enough food or heating to go around, but the people who lived in Leningrad refused to surrender to the Germans.
In 1940, the French port of Dunkirk was the location of a big turning point for the Allie:in World War II. Hitler's armies bombed Dunkirk heavily, and many Allied troops were waiting on the beach to be rescued because they didn't have the resources they needed to fight back. From 26 May to 4 June, over 550, 000 troops were ferried to safety across the English Channel-the code name for this was 'Operation Dynamo'. Some British civilians(people who weren't in the army)even used their own boats to help save as many people as they could. The rescue operation helped to boost morale(士气)in Britain, where they really needed some good news. This helped in going into the next major event in World War II, the Battle of Britain.
June 6,1944 is also known as D-Day. On that day, the Allied forces launched a huge invasion of land that Adolf Hitler's Nazi troops had taken over. It all began with boats and boats full of Allied troops landing on beaches in the French region of Normandy. They broke through the German defences and carried on fighting them back through Europe for the next 11 months until they reached Berlin, where Hitler was then hiding.

Cheer-leading began in all-men colleges in late nineteenth and early twentieth centuries. As time passes, more and more colleges started cheer-leading and more women started doing it. It was not until the 1920s when pompoms began to play an important part in cheer-leading. At about the same time, cheerleaders began to include gymnastics in their routines. Found at most athletic events, and cheer-leading competitions are an important part of school and college life. Nowadays, many American are amused by cheer-leading.
