Children know that summer is probably the most fun of all seasons. However, experts say it is also the most dangerous, especially for children aged 14 and under. In its first study of children’s safety in the US, the National Safe Kids Campaign (NSKC) found that nearly half of the injury-related(与受伤相关的) deaths among children happened in summer.
Experts are not surprised by the study’s results. They always know summer is a dangerous season for children. During the summer, children are out of school and spend more time outdoors. They are more likely to get into an accident or be injured. “While we encourage children to be active and spend more time outdoors, they need to understand the importance of safety,” said Everett Koop, an expert of the NSKC.
To help children stay safe, the NSKC started a “Make it a Safe Kids Summer” Campaign during National Safe Kids Week, from May 5th to May 12th. Here are some important summer safety tips from the NSKC:
●Always wear your seat belt.
●Make sure there is an adult around when you decide to go swimming.
●Wear a life jacket(救生衣) when on a boat or doing water sports.
●Obey all traffic rules.
●Don’t meet e-pals alone.

Leonardo da Vinci's(达芬奇) mother may have been a Chinese slave(奴隶) according to a new research by an Italian -Angelo Paratico. He has spent the last 20 years living and working in Hong Kong, researching the links(联系) b1. his homeland and China.
It is believed that Leonardo da Vinci's mother was named Caterina, who, according to some reports, was a local farmer. But Mr. Paratico's new work leads to a d2. explanation.
Speaking to the South China Morning Post, Mr. Paratico said, “I am s3. that Leonardo's mother was from the East, but to make her a Chinese, we need to use a deductive method (演绎法).”
Angerlo Paratico has s4. many documents(文献). He found that one wealthy friend of Leonardo's father’s had a slave called Caterina. After Leonardo's date of b5., she disappeared from the documents. “She was no longer working there and could not be found,” Paratico a6.. Supporting his opinion, he said, “During the period, countries like Italy and Spain were f7. of slaves from the East.”
He said that there were certain aspects(方面) of Da Vinci's life and works which suggest a Chinese link. An e8. is that he was writing with his left hand from left to right. And he was a vegetarian(素食者), which was not common. Mona Lisa(蒙娜丽莎) is probably a picture of his mother. On the back of Mona Lisa, there is a Chinese landscape and e9. her face looks Chinese.
Mr. Paratico said the only way to s10. the mystery is to extract(提取) some DNA. But he said he preferred to let the mystery remain mysterious.

In the western Pacific Ocean lies the deepest place on the planet — the Mariana Trench, which runs as deep as about 7 miles below the ocean’s surface. That’s greater than the height of Mount Everest measuring about 5 and a half miles above sea level.
The Mariana Trench is home to a variety of sea life. Coral reefs and underwater volcanoes are all found there. But because few humans have been able to go far into the trench, scientists know little about it.
Now they are working to change that. Recently, the Okeanos Explorer has been on an exploration there. Remotely operated vehicles sent out from it are taking videos of life in its deepest, darkest areas. Scientists around the world, along with the general public, can watch the videos in real time. These videos are showing the most mysterious parts of the ocean. Much of the area that the Okeanos Explorer is exploring has been protected since 2009 as part of the Marianas Trench Marine National Monument. Covering more than 95,000 square miles, it is one of the world’s largest marine protected areas.
It’s very dark, so the animals must use many other senses other than sight to understand their surroundings, find food and escape from enemies. The water is also very cold — slightly above freezing — and its pressure is extremely high. That means only certain animals can live there, like shrimp, crabs, and starfish.
So far, the expedition’s cameras have filmed a variety of rarely seen deep-sea creatures, including ghost sharks, huge lobsters, and sea pigs. Perhaps the most amazing sight is beautiful red jellyfish that scientists have never seen before.
Scientists hope this expedition will help them unlock the mysteries of the Mariana Trench. They’ll learn about the deep-sea animals and plants found there. They’ll also study its unique features, including underwater mountains, mud volcanoes, and hot springs produced by the volcanoes.
They say that this knowledge will also help scientists better understand how the deepest part of the ocean affects the rest of the world. "The ocean plays a role in the air we breathe, the food we eat, and the transportation of the goods we buy — not to mention the weather and climate change," a scientist said. "The deep sea may also hold cures for diseases. How will we know what is out there if we aren’t looking into it?"

China says 16 endangered finless porpoises（江豚）have been found dead since the beginning of the year and experts blame water pollution and climate change for pushing the species toward extinction．
The freshwater porpoise-popularly known in Chinese as the"river pig"-mainly lives in China's Yangtze River and two lakes linked to the river．
Authorities（官方）have discovered 10dead porpoises in Dongting Llake in the central province of Hunan since March, according to a statement by the government of Yueyang City, which is located on the lake's shore． Another six dead porpoises have been found in Poyang Lake in the eastern province of Jiangxi since the beginning of the year． Experts warn that the species will be extinct within a matter of years．
Wang Kexiong, a researcher at China's Institute of Hydrobiology, said water pollution, shipping and sand dredging（挖掘）were all possible contributing factors to the recent deaths．
Many rivers in China have become heavily polluted with poisonous waste from factories and farms-pollution blamed on more than three decades of rapid economic growth and slow enforcement（实施）of environmental protection laws．
The report said climate change also could be to blame as the dry weather has caused water levels to drop and makes it more difficult for the porpoises to find food． Tests have shown that some of the porpoises are believed to have died of starvation（饥饿）．
In 2006, China was estimated（估计）to have only 1,200 finless porpoises left． That same year, the Baiji-a freshwater dolphin also native to the Yangtze River-was declared extinct． Earlier this year, a survey found just 65"river pigs"in Dongting Lake and 300-400 in Poyang Lake．
Following the recent deaths, Yueyang City promised to investigate and increase protection of the remaining porpoises in Donting Lake．
