1 . A new study suggests that some homemade soups — made of chicken, beef or vegetables — might help fight malaria.

Jake Baum of the Imperial College London led the research. He asked children at a London school to bring in homemade clear soups that their families would make to treat a fever. The soups were then exposed to the parasite (寄生虫) that creates 99.7 percent of malaria cases in Africa, the World Health Organization explained.

Of the 56 soups tested, five were more than 50 percent effective in containing the growth of the parasite. Two were as effective as one drug now used to treat malaria. And four soups were more than 50 percent effective at preventing parasites from aging to the point that they could infect mosquitoes that spread the disease. Baum also noted that it was unclear which foods made the soups effective against malaria.

The soups came from families from different ethnic histories, including Europe, North Africa and the Middle East. They had several main ingredients, including chicken, beef and green vegetables. Baum said the vegetarian soups showed similar results to the soups with meat.

Baum said his aim was in part to show children that scientific research can turn a herbal (草本的) cure into a man-made medicine. He noted the research of Dr. Tu Youyou from China. In the 1970s, she found that the herb qinghao was an effective antimalarial (抗疟疾的) treatment. The herb has been used in Eastern medicine for two thousand years. Tu’s research led to the man-made drug artemisinin (青蒿素), a drug now widely used to treat malaria.

More and more people are becoming resistant (耐受的) to the drugs that treat the disease, which kills nearly 400,000 people a year. That means scientists will have to “look beyond chemistry” and find new drugs, Baum adds.

2 . The Internet has become a part of human life. There’s a report on 3, 375 people aged from 10 to 38 in seven Chinese cities. It says that 38 percent of them believe they use the Internet often. While most of them get useful information and use the Internet in their works and studies. Some are not using it in a good way. Many are playing online games too much. A few even visit websites they should not look at. It seems that we can’t live in a world without the Internet.

Actually, we are all busy talking about and using the Internet, but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system (系统) had to be set up.

It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time. At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet easier.

Today it is easy to get online and it is said that millions of people use the Internet every day. Sending e-mails is more and more popular among young people. The Internet has now become one of the most important parts of people’s life.

3 . One of the most important things of the U. S. government’s routine in 2020 is to raise the federal (联邦) legal age for buying tobacco from age 18 to 21.

Beginning in the summer of 2020, it will be against the law to sell tobacco to anyone under the age of 21. Since 1990, the legal age permitted to buy cigarette is at least 18. The law also includes e-cigarette, not just traditional tobacco products like cigarettes and cigars, adding regulation to this industry, which has developed largely unchecked.

The use of E-cigarette has increased sharply among U. S. teenagers. According to the U. S. Department of Health and Human Services, 27.5% of U. S. high school students have used e-cigarette in the past month. Raising the age one can buy tobacco is intended to avoid what many people are calling an epidemic, which is doing great harm to the health of American teenagers.

A recent outbreak of the disease related to e-cigarette has raised even more concern about e-cigarette products , although the disease is largely linked to cartridges (药筒) filled with addictive Vitamin E acetate sold in black market.

In a statement to TIME, the American Lung Association considered raising the age one can buy tobacco as an easy way to protect children’s health and prevent them from getting addicted to nicotine.

Those in favor of e-cigarette have made it clear that they support raising the legal age permission for buying and using tobacco, arguing that e-cigarette products are never designed for young people. Some anti-cigarette (反对吸烟) people have expressed their doubt of this opinion.

At present, twenty states have already raised the legal age to buy cigarette to 21.

4 . Music just like sunshine, it can always touch our heart no matter when we are happy or sad. It’s evident that musicians are great in our mind no matter they are alive or they have been dead for years.

Montreux, Lake Geneva, Switzerland

After passing away in 1991, Freddie Mercury’s body was burned and his ashes spread around in Lake Geneva. A statue of the lead singer of Queen was unveiled (揭幕) on November 25,1996, and overlooked the lake.

Nine Mile, Jamaica

In the village of Nine Mile lies a statue built just feet away from Bob Marley’s childhood home, where the Reggae singer was buried after his death in 1981. In 1991, the Jamaican government declared Marley’s birthday, February 6, a national holiday, and Nine Mile held an annual music festival in honor of the singer.

Joshua Tree National Park, Joshua Tree, Calif.

Gram Parsons was a regular visitor to Joshua Tree National Park until his death in 1973, and he and his friend Phil Kaufman made an agreement that whoever died first, the survivor would take the other guy’s body to Joshua Tree and burn it. This agreement would be the foundation for one of the greatest stories in rock and roll history. Today, there is a Gram Parsons statue in Joshua Tree National Park.

Stone Mountain, Ga.

After one of the most unfortunate deaths in hip hop history, the Tupac Amaru Shakur Foundation was developed by Tupac’s mother in 1997. The foundation began a center for the arts in 2005 as a youth arts training program. Located in Stone Mountain, the center has a garden with a statue of the late rapper.

10 . In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christian-sen became puzzled about something that, strangely, had not troubled anyone before he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature—that is what accounted for all its hot springs and other steamy features. But Christian-sen couldn’t find the Yellowstone volcano anywhere.

Most of us, when we talk about volcanoes, think of the classic cone(圆锥体)shapes of a Fuji or Kilimanjaro, which were created when erupting magma(岩浆)piled up. These can form remarkably quickly. One day in 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile-across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn’t involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera(火山口).Yellowstone obviously was of this second type, but Christian-sen couldn’t find the caldera anywhere.

Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up(放大的照片)for one of the visitors’ centers. As soon as Christian-sen saw the photos, he realized why he had failed to spot the caldera: almost the whole park—2.2 million acres -was a caldera. The explosion had left a hole more than forty miles across-much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with violence far beyond the scale of anything known to humans.
