International teams have spent nearly half a year looking for evidence of the missing Malaysian Airlines plane, a search that includes the hunt for the aircraft’s so-called black box, which holds flight data that would likely explain what caused MH370 to move away from its course. But many aviation experts wonder why, in our increasingly networked world, divers are searching the Indian Ocean for a metal box when technology already exists that would enable planes to stream black box data to the ground in the event of an emergency.

Black boxes have been on planes since the late 1950s, and now every commercial aircraft has two: a flight data recorder and a voice recorder. (Although they are referred to as black boxes, they are typically orange in color, making them easier to spot in waters.) Black box recorders are mainly used to investigate the cause of in-flight accidents.

While black boxes are built to survive a crash and long-term submersion(浸没)in water, it can be a real challenge to find the device if a plane has gone down in the ocean. While each box contains a beacon(无线电信标台), the unit only has enough battery power to transmit a signal for 30 days. After the crash of Air France Flight 447 in the Atlantic Ocean in June 2009, it took divers two years to find the black box.

Pierre Jeanniot, a Canadian engineer who helped perfect black box technology about 40 years ago, feels that the device, in its current form, is “obsolete”. He started to question its effectiveness more than a decade ago, after seeing the broken pieces of the black boxes in the 2001 attacks on the World Trade towers in New York. Jeanniot is now on the advisory board of a Toronto-based firm that has built a live-streamed black box system. When a plane experiences an irregular event, the system can send streaming data off the aircraft to one of the satellites and then down to ground-based servers, where the message is interpreted and sent to the airline. It seems necessary that the loss of MH370 and other similar cases wake more people up to the fact that the tools being used at this stage are inadequate for dealing with emergency situations, Jeanniot says. He also estimates that if this technology had been on board the missing Malaysian Airlines flight and live-streaming for the estimated seven hours after the flight first experienced a problem, it would have cost about $3,000.

While there is widespread approval of a live-streamed black box system, most airlines see its cost prohibitive. The airline industry is an industry with small profits, and is reluctant to add costs that will further cut the bottom line.

However, given how much time, money and effort has been spent on the luckless search for MH370, s black box, the cost of operating a live-streaming version seems like a trifle(区区小数)

Two workers was rescued 188 hours after they trapped in a coal mine collapse(倒塌)in the south China’s Guangxi Zhuang Autonomous Region The two were among 18 miners trapped after the mine, collapsed midday on July 2 because of days of heavy rain.

A total of 71 miners were working underground when the accident occurred on July 2---49 managed to escape. Rescuers have got eight bodies so far.

Ye Fangyong, commander of the rescue headquarters, said that the place where the survi- vors were found was at 320 meters underground. It was filled with mud after the collapse, but there was still room for fresh air. He said three more miners trapped at a work platform390 meters underground may survive because the place also have some space for fresh air.

Rescuers had believed that four other miners would be found with the rescued two, but the chances of the remaining 12 being found alive are not good due to the conditions in the mine.

However, the rescuers have not given up. They are using scientific measures such as a water-proof radar device(裟置)to help find the exact locations of trapped workers. Moreover, rescuers have been offered 2 million yuan for each miner they pull out alive.

The two survivors have been identified a) 41-year-old Liu Jiagan and 35-year-old Qin Hongdang. They are in safe condition.

Before they were rushed to Heshan People's Hospital for treatment, they told rescuers in weak voices that they survived under the mine by drinking spring water that seeped(渗漏) through the top of the shaft(矿井).

I sat with my friend in a well-known coffee shop in a neighboring town of Venice. As we our coffee, a man came in and sat at a(n) table beside us. He called the waiter and placed his saying, “Two cups of coffee, one of them there on the wall”.

When 19-year-old Sophia Giorgi said she was thinking of volunteering to help the Make-A-Wish Foundation(基金会),nobody understood what she was talking about .But Sophia knew just how important Make – A –Wish could be because this special organization had helped to make a dream come true for one of her best friends .We were interested in finding out more, so we went to meet Sophia and listened to what she had to say .

Sophia told us that Make – A –Wish is a worldwide organization that started in the United States in 1980.It’s a charity(慈善机构)that helps children who have got very serious illnesses.

Sophia also told us the Foundation tries to give children and their families a special, happy time. A Make-A-Wish volunteer visits the families and asks the children what they would wish for if they could have anything

in the world. Sophia said the volunteers were important because they were the ones who helped to make the

wishes come true. They do this either by providing things that are necessary, or by raising money or helping out in whatever way they can.
