You never see him, but they're with you every time you fly. They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device(装置) was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
1.In Paragraph 1,the author wants to say the black box_________.
A. is an necessary device on an airplane
B. comes from a comic book

D. can control the function of an airplane
2.From the black box on the Yemeni airliner_________could be found.
A. the scene of the crash and the degree of the damage

It’s not every day that you see pigeons(鸽子)with cowboy hats on their tiny heads walking or flying around, unless you live in Las Vegas, where cowboy-hat-wearing pigeons are actually a thing people have been constantly taking about these days.
It all started on December 5, when a Las Vegas citizen named Bobby Lee noticed two funny-looking birds walking near a dustbin. The pigeons drew his attention because they were wearing tiny cowboy hats — one red and one grey — so he took out his smartphone and started filming them. Later, he uploaded the video online, where is quickly spread. The next day, everyone was talking about Las Vegas’ cowboy-hat-wearing pigeons, and Lee was getting phone calls from agencies trying to license his video.
It was only a matter of time before news outlets picked up the story and reported on the mysterious pigeon cowboys spotted around Las Vegas. The only link anyone could think of was the Wrangler National Rodeo Finals that were taking place in town at the time, but the Professional Rodeo Cowboys Association, which organized the event, denied any involvement.
While some netizens just found the idea cute and jumped at the opportunity to catch the pigeons on camera if they spotted them around Vegas, others expressed concern about the birds’ well-being. They even mentioned animal cruelty.
Hillman, the founder of local pigeon rescue Lofty Hopes, said that her organization was trying to track down the birds and remove their hats, but trapping them with food has proven very difficult so far. That’s because the two known cowboy-hat-wearing pigeons have become very popular around Las Vegas, and people are constantly throwing them much food.
“When you see them today, you could see some loose feathers in the glue around the hat, and it’s surely a concern,” Hillman said, adding that she believed the hats had been glued on with a strong adhesive (粘合剂).
