American soldier Bowe Bergdahl has returned to active duty in the United States Army. The Taliban in Afghanistan kidnapped and held Sergeant Bergdahl for five years.
An Army spokesman said Monday that Sergeant Bergdahl has completed the final part of the recovery process. He said the soldier is being sent to a U.S. Army base near San Antonio in the southern state of Texas, where he can, in the spokesmans words, "contribute to the mission."
A U.S. Defense Department spokesman said Sergeant Bergdahl will be doing administrative work. The Army said an investigation continues into the facts surrounding his disappearance and capture.
U.S. Army Sergeant Bowe Berghdal is pictured in this undated handout photo provided by the U.S. Army.
Military officials say he walked away from his base in Afghanistan in 2009. Some of his former military workers say he willingly left his group, or unit.
The Afghan Taliban released the sergeant May 31 in a prisoner exchange. The U.S. released five Taliban leaders held in U.S. military prison at Guantanamo Bay, Cuba. The exchange caused intense debate. The Taliban detainees were sent to Qatar. The Qatari government has said it will watch the five men for a year.
Sergeant Bergdahl was examined at a U.S. military hospital in Landstuhl, Germany, after his release. He later was moved to a military hospital at Fort Sam Houston in Texas for treatment. Reports say he will live in military housing at the base in Texas.
Sergeant Bergdahls release led to celebration in the United States. But that turned into a political debate about whether he had left his post and whether the prisoner exchange should have taken place.
2017年6月大学英语四级听力在线练习 篇2The Brazilian government says it invested billions of dollars to prepare for the 2014 World Cup. The money has been spent on infrastructure like roads and stadiums for World Cup events. It also has paid for security and social projects. The government says these investments will result in long-term gains for Brazil, but independent experts say effects of the spending are mixed.
Urban planners say the $11 billion spent on stadiums and infrastructure has created jobs for poor Brazilians, but they say this development has a price. The public works have driven up the cost of housing. This, say some experts, has push poor people further away from jobs and public services.
Brazil stars mourn unhappy ending
Some people are questioning the value of Police Pacification Units, called the UPP in Portuguese. Officials have sent the special police forces to drive out drug traffickers and other criminals. But the results have been mixed, says Chris Gaffney. He teaches at Fluminense University in Rio de Janeiro.
Professor Gaffney says the drug traffickers just move their operations to other favelas. But he adds that the UPP have brought some order to once lawless neighborhoods.
"These places were closed in many respects to the formal market. But the UPP goes in [to the favela] and it removes the barrier of the drug traffickers and allows all kinds of market forces to flow through it," explained Gaffney.
He says these forces have opened some areas to tourism or state-support projects or businesses. The organizing body of the World Cup, FIFA, also invested in social programs.
Lisa Delpy Neirotti is with Georgetown University in Washington D.C. She says the investments have led to programs for educating young people about the environment, the disease AIDS, or the importance of staying in school. She says FIFA pressure the Brazilian government to accept some pro-environmental measures like treating and reusing waster at stadiums.
FIFA also wanted the structures built for the World Cup to meet the guidelines of LEED, or Leadership in Energy and Environmental Design. The U.S. Green Building Council set up the LEED Certification Program to recognize best in class building policies.
Brazils government says the World Cup will add billions of dollars to the economy, but many Brazilians believe the money will go to only a few people.
Critics note some cities in Europe have rejected proposals to hold huge sporting events. They say a new models is needed if nations organizing such activities are to avoid protests like those earlier in Brazil.
2017年6月大学英语四级听力在线练习 篇3The end of the World Cup does not mean the end of international competition in Brazil this year. A major football event will happen in the South American country later this month, but with teams of robots playing the game, which is known as soccer in the United States. The robot teams are guided by teams of humans from around the world. The event is known as RoboCup.
Technology students at the University of Pennsylvania are trying for their fourth victory at the competition, which is held this year in the coastal city Joao Pessoa. The students have won the last three RoboCup competitions.
US students prepare for robotic football championship
Watching robots play football is similar to watching children play the game. The kicks are not good, theres a lot of falling down, and people are there to guide and support the team members. Jian Qiao Li is one of the leaders of the University of Pennsylvania team.
He says one goal he has for the robot team is to make sure the machines can find the goal and the ball. He also wants the robots to be able to know where they are on the playing field. And he wants the team to be able to better control the walking and kicking abilities of the robots.
Qin He is another leader of the robot team. She says the abilities of the robots increase every year. Ms. He says the US team is meeting its goals.
The robots know the differences between the colors green and red, and they can decide where to go and where the ball is on the playing field. She says if there are three robot players on the field at the same time, they will communicate with each other to decide the different responsibilities for each robot.
U.S. team member Christopher Akatsuka hopes for another victory in Brazil. The team has won the RoboCup the past three years in the Netherlands, Mexico and Turkey.
"They have very good team player right now. As long as their detection is good, I think theyll be very competitive; we just hope to compete against the real good German teams, because the Germans always do very well," says Akatsuka.
Mr Akatsuka says RoboCup is an exciting technology competition.
"Each team develops their own software; basically its a competition of who has the best software, who has the best decision-making at a given point... its really exciting," says Akatsuka.
The event begins July 19th and ends July 25th. Some RoboCup participants hope to develop a team of robots that can play against humans by 2050.
