【推荐1】Two teenagers are lost at sea off the coast of the United States for six days on their small sailing boat. Without any food and drink, the boys drink sea water. They try slipping into the ocean to cool off, but sharks drive them back onto the boat. At night, they use a single wet suit to keep warm.
This is a real story of two American boys. Driscoll and his best friend, 18-year-old Josh Long, were found six days later and more than 100 miles from where they had set off from Sullivan’s Island, South Carolina, on April 24. The boys had lost a lot of water and were tired, but otherwise in pretty good shape.
They set out fishing on a 4.3-meter sailboat on a windy day when the National Weather Service had warned small boats to stay out of the water, but they didn’t care. They realized they were in trouble almost immediately and tried to swim back to shore, pulling the boat along with them. Within hours, they were far out to sea.
“We lost our fishing equipment, ” Driscoll said. “So we couldn’t catch any fish. ” The boys’ hopes faded with each day passing. They stood on their boat every time they saw another boat, waving and shouting, but without success. One night they were woken up by water coming into the boat. A large ship was very close to them.
A coast guard boat set out to look for them. The boys got up and made some noise. This time, they were heard.
“What we have is a completely surprising story of survival that’s going to be studied for years to come, ” said Richard Goerling, Long’s uncle, “I think the boys have a book to write. ”

Mickey Wilson had been on the mountain only a few seconds when he heard the scream. Wilson, 28 years old, had just gotten off the cable car (索道缆车) at the Arapahoe Basin Ski Area in Keystone, Colorado, along with his friends Billy Simmons and Hans Mueller. Their friend Richard had been on the cable car ahead of them, but when the men reached the top of the lift, he had disappeared. The men walked toward the source of the scream and found skiers stopped on the slope, pointing to the cable car. And then the friends screamed too.
“Oh, Richard!” yelled Mueller.
When Richard had tried to jump off the cable car, his backpack had been caught in the chair, which then dragged him back down the hill. In the process, the backpack belt twisted around his neck, making him breathless. Now Richard’s body was swinging four feet above the snow. The cable car operator had quickly stopped it, and the friends kicked off their skis and ran toward the scene. They made a human pyramid to try to reach Richard, but the unconscious man was too far off the ground. With the clock ticking, Wilson ran to the ladder of a nearby lift tower. Scared skiers watched as he struggled the 25 feet. After he reached the top, Wilson’s first challenge was to climb onto the two-inch steel cable that held the chairs. He handled the balance and height bravely, but he knew he could not walk on the cable. Therefore, he calmed down and sat over it and then used his hands to pull himself to Richard quickly. Wilson’s greatest fear wasn’t that he’d fall, but that he wouldn’t reach Richard. “This was life or death,” he said.
When he reached Richard’s chair, Wilson swung a leg over the cable and attempted to drop down onto it. But as he did that, his jacket caught on the movable footrest, which was in the up position. The footrest began to slide down, with Wilson attached. But before that could happen, he managed to free himself and reached Richard.
Fortunately, the ski patrol (巡查) had gathered below and performed emergency treatment on Richard, who had been hanging for about five minutes, then skied him down to an ambulance.
That night, Richard called from the hospital to express his thanks to Wilson, his other friends and the workers at the Arapahoe Basin Ski Area.

【推荐3】An Uber self-driving car hit and killed a woman crossing the street in Arizona, U.S., police said on Monday, marking the first death caused by an autonomous vehicle and a potential blow to the technology expected to transform transportation.
