一. 马航事件(创新科技类话题)
We can see countless millions of milesinto the blackness of space, but a 3-mile depth in the ocean is testing thevery limits of our technology because most of it just doesn’t work underwater.
As the hunt for Malaysia Airlines Flight370 demonstrates, at that depth —minuscule compared with the vastness of space —everything is a virtual unknown. A high-tech unmanned underwater submarine,Bluefin-21, has been dispatched four times to look for wreckage from the jet,but the crushing water pressure and impenetrability of this void mean that onlyits most recent pair of missions were completed. Scrutinizing dust and rockparticles on the Red Planet, tens of millions of miles away, is a breeze.Understanding what’s on the seafloor of our own planetis not.
About 95% of deep ocean floor remainsunmapped, but that’s almost certainlywhere the most sought after aircraft in history is going to be found. “Our knowledge of the detailed ocean floor is very, very sparse,” Erik van Sebille, an oceanographer at the University of New SouthWales in Sydney, tells TIME.
The reason for our ignorance is simple.Virtually all modern communications technology —be it light, radio, X-rays, wi-fi — is a form ofelectromagnetic radiation, which seawater just loves to suck up. “The only thing that does travel [underwater] is sound,” says van Sebille, “and that’s why we have to use sonar.”
Sound is formed by mechanical waves andso can penetrate denser mediums like liquids: but at a 3-mile (5 km) depth, evensonar starts to have problems establishing basic parameters. The waters inwhich the search for MH 370 is happening, for example, were thought to bebetween 13,800 and 14,400 ft. (4,200 and 4,400 m) deep, because that’s what it said on the charts that had been drawn up over time bypassing ships with sonar capabilities. It turns out those seas are at least14,800 ft. (4,500 m) deep. We only know that now because that’s the depth at which Bluefin-21 will automatically resurface — as it did on its maiden foray — whenonboard sensors tell it that it’s way, way out of itsoperating depth. The problems with Bluefin-21, van Sebille says, show us that “even our best maps are really not good here.”
The other issue affecting visibility isthe sheer volume of junk in the ocean. About 5.25 trillion particles of plastictrash presently billow around the planet, say experts, weighing half a milliontons. There are five huge garbage patches in the world’s seas, where the swirling of currents makes the mostly plastic debrisaccumulate. The largest of these is the Great Pacific Garbage Patch, a gyremeasuring an estimated 270,000 to 5.8 million sq. mi. (700,000 to 15 million sqkm). This refuse gets ingested by plankton, fish, birds and larger marinemammals, imperiling our entire ecosystem.
Flotsam debris has already impeded thehunt for MH 370. Hundreds of suspicious items spotted by satellite have sentaircraft and ships on hugely costly detours to investigate what turned out tobe trash. (On Friday an air-and-surface search continued, with 12 aircraft and11 ships scouring an area of some 20,000 sq. mi. [52,000 sq km] about 1,200miles [2,000 km] northwest of Perth.)Officials are saying that such efforts are becoming futile.
For all we know, Bluefin-21 could alsobe confused by the sheer volume of garbage down there. According to a study bythe Monterey Bay Aquarium Research Institute published last June, based on8,000 hours of underwater video, an unbelievable quantity of waste is strewnacross the ocean floor. A third of the debris is thought to be plastic — bags, bottles, pellets, crates — but thereis a vast amount of metal trash as well, including many of the 10,000 shippingcontainers estimated to be lost each year.
“I was surprised that we saw so much trashin deeper water,” said Kyra Schlining, lead author onthe study. “We don’t usuallythink of our daily activities as affecting life two miles deep in the ocean.
That’sbecause we can’t see it. It’stempting to say that MH 370 might as well have vanished into space — only if it had, we’d have found it by now.
二. 奥巴马新移民政策 (政权类话题)
President Obama has long insisted hedoes not have the power to waive deportations of illegal immigrants on his own.
But under pressure from politicalallies, Mr. Obama may be headed for some changes of immigration policy via theDepartment of Homeland Security. DHS Secretary Jeh Johnson is consideringlimiting deportations of undocumented immigrants who do not have seriouscriminal records, the Associated Press reported Monday.
Obama set the stage for the reportedrecommendations last month, when he ordered Secretary Johnson to review howcurrent immigration law is implemented, with an eye toward conductingenforcement “more humanely,” asthe White House put it.
The change of policy, if adopted, “could shield tens of thousands of immigrants now removed each yearsolely because they committed repeat immigration violations, such as reenteringthe country illegally after having been deported, failing to comply with adeportation order, or missing an immigration court date,” the AP reported.
Such a move would fall short of thelarger changes pro-immigrant activists are hoping for, such as granting workpermits to the illegal-immigrant parents of American-born children. At the sametime, any unilateral move by the administration that grants new rights tocertain illegal immigrants would likely anger Republicans, who accuse Obama ofabusing his executive powers.
The president has long said the only wayto achieve comprehensive immigration reform is to go through Congress. Butalmost a year after the Senate passed reform legislation on a bipartisan vote,the Republican-controlled House has yet to act.
三、Emily Cox (适用思想品德，成功与失败等话题)
Perhaps after hearing this young lady'sstory, Harvard will move her from the wait list to accepted status.
As the 118th Boston Marathon beginsMonday, Fairfax (Va.)W.T. Woodson High senior Emily Cox is the youngest female competitor in thefield of 36,000, according to a fantastic Washington Post feature.
Marathons run in Cox's blood. Hergrandfather John Jr., a World War II veteran, got the family running.Literally. They've reportedly competed in 101 Marine Corps Marathons since1986. According to The Washington Post, Emily ran her first marathon to honorher grandfather's death in August 2011 —finishing in 4:35.08 despite never training — and thisyear's 26.2 miles will have similar significance.
"I'll have something to run forthis year, more than me just trying to finish a marathon,” she told the paper. "Ultimately I know I’ve trained well. I have to trust my training and have fun. I want tohave a smart pace, go out and just enjoy it, enjoy the experience, enjoy Boston and be part ofsomething bigger than myself."
Cox qualified for the first Boston Marathonsince the bombings in 2013 with a time of 3:31.51 at last year's Marine CorpsMarathon, according to The Washington Post. She turned the minimum age of 18 onMarch 30, making her the youngest female to take to the starting line in Hopkinton, Mass.
All of this despite running just oneseason for Woodson. Her endurance comes from years of tennis completion beforedropping the sport to focus on academics as a high school freshman, the papersaid. Instead, she has reportedly run nine miles a day since her sophomoreyear, waking up daily at 3:45 a.m.
Meanwhile, many of her peers would besleeping seven hours later if they had their druthers. It seems there's areason she's been accepted to Brown University, the Universityof Virginia and the College of Williamand Mary. Harvard and Columbiareportedly wait-listed her. Considering she's running in the Crimson's backyardon Monday, perhaps they'll finally recognize this trailblazing teen.
