The US plans to extend its endangered species protection to lions in Africa. US Fish and Wildlife Service (FWS) will classify lions in southern and eastern Africa as threatened. The move will place tighter restrictions on the import of lion “trophies(纪念品)”, such as paws or heads.

While the US cannot regulate hunting in other countries the move is significant because around half of all lion hunting in Africa is conducted by Americans. According to FWS data, more than 5, 600 lions have been killed and imported by American hunters over the past decade.

Under the new FWS rules, bringing lion parts to the US will be banned(禁止) in most circumstances if the animal is from a country where lions are endangered. Hunters will have to show the trophies were “legally obtained” from countries that have a scientifically sound management program that benefits the subspecies in the wild.

This regulation is expected to place a far greater burden of proof upon hunters who claim that the money from lion hunting has been used to help communities in Africa and the overall conservation of lions. The persistent downward trend in lion numbers, due to habitat loss and hunting by locals and foreign tourists, suggests there has been little conservation(保护) benefit from organized hunts.

An international study, published in September, found African lion numbers have decreased by half since 1993, with a further 50% decline expected over the next 20 years for populations in west, central and east Africa.

“The lion is one of the planet’s most beloved species and an irreplaceable part of our shared global heritage,” said Dan Ashe, director of the FWS. “If we want to ensure that healthy lion populations continue to wander around the African savannas(大草原) and forests of India, it’s up to all of us—not just the people of Africa and India--to take action.”

2.Where do most of the lion hunters come from?

C. Eastern Africa. D. India.

3.What may be the result of the move?

A. The import of lion parts will be strictly limited.

B. Lion-hunting will be illegal all over the world.

C. communities in Africa will benefit a lot.

D. Lion parts will never be legally obtained.

4.What does Dan Ashe really want to tell us in the last paragraph?

A. Almost everybody loves lions.

B. It’s everyone’s duty to protect lions.

C. Lion populations will increase rapidly.

D. Measures must be taken to keep lions fit.

Cathy is a tetraplegic. She has not been able to move her arms, legs or speak since suffering a stroke(中风)nearly fifteen years ago. Recently, she learned how to control a robotic arm using her thoughts. She now can use brain activity to serve herself a drink.

The American woman is one of two people who took part in a research project known as BrainGate2. The researchers have spent years studying how to help people who are disabled regain movement in their arms and legs.

John Donoghue is a neuroscientist with Brown University and also was part of the project. He said, “People like Cathy have their brain disconnected from their body. So they are not able to go out and do everyday things that you and I can do, like reach for a glass of water or scratch your nose. Our idea is to avoid that damaged nervous system and go directly from the brain to the outside world, so the brain signals can, not control muscles, but control machines or devices like a computer or a robotic arm.”

The two disabled people had small sensors connected to the part of the brain that controls movement. The devices measured brain activity and sent that information to a computer. The computer has special software that turns the information into digital commands for operating other devices. The researchers used a highly developed robotic arm to recreate human actions.

The BrainGate team had its first success in 2006. A tetraplegic stabbing victim was able to use the brain—computer system to control a computer mouse. John says the latest development using robotic arms is a major victory.

A video of the latest experiment shows Cathy using the robotic arm to pick up a cup of coffee. She guides the cup toward her mouth, moves it forward and drinks through a straw.

Lead researcher Leigh Hochberg said the first time she did it was a magic moment.

The research team carried out almost 200 tests with two different robotic arms, which were able to pick up their target objects 43% to 66%of the time.

The researchers are calling the information very promising. But they say it will take years to fully develop the technology for everyday use.

1.What kind of symptoms may a tetraplegic have?

A. He/She may suffer from amnesia and a loss of concentration.

B. His /Her part of body may become sore and swollen.

C. He/She may get frequent headaches or backaches.

D. He/She can’t move his/her arms or legs and has no ability to speak.

2.How does the robotic arm work?

A. brain signals small sensors muscle a robot arm

B. brain signals the nervous system musclea robot arm

C. brain signals small sensors a computer a robot arm

D. brain signals the nervous system a computer a robot arm

3.What can we know from this passage?

A.The technology had been put into use before 2006.

B.It won’t be long before the technology comes into daily use.

C.The two robotic arms couldn't pick up their target objects.

D. Quite a few experiments have been conducted for the technology.

4.What's the purpose of the research project?

A.To help the disabled people to move and speak.

B.To help the brain-computer system to control a computer mouse.

C.To help the disabled people use brain activity to serve themselves a drink.

D.To help the disabled people to get movement like having their arms and legs again.
