After record increase in over 40 countries, Universal Robots' lightweight robotic arms are now making their US debut at this year's International Manufacturing Trade Show (IMTS) in Chicago. The UR5 robotic arm made by Universal Robots has been announced officially "The world's most innovative robot" by The International Federation of Robotics and IEEE (Institute of Electrical and Electronics Engineers) Robotics and Automation Society. The US audience will now see the award-winning robot -- along with its big brother UR10 -- for the first time. The UR5 and UR10 robotic arms are aimed at small-sized companies that thought robots were too expensive and hard to operate in existing production. The robotic arms are easily moved around the production area and present a simple user interface which lets workers quickly operate them. Esben Ostergaard, founder and CTO (Chief Technical Officer) at Universal Robots, explains how the robots were designed to be as user--friendly as possible: "We decided to make programming easy by developing a user interface worked together with a "teaching function" allowing the user to simply took hold of the robot arm and show _ how a movement should be done. The robot can work in any production process very quickly. Our experience shows this is generally done in a few hours." The robots weigh as little as 40 pounds, making it possible for them to be moved around the production area to do different tasks. The UR5 can handle a load of up to 5 kilos (11 pounds), the UR10, 10 kilos (22 pounds). As soon as a worker touches the robot arm and uses a force of at least 150 Newton, the robot arm will automatically stop operating. According to the text, the UR5 robotic arm _ . A) was designed by IEEE B) is aimed at small companies C) has won a number of awards D) made its appearance in 40 countries

The nation's largest group of pediatricians on Monday urged its members to "firmly oppose boxing for any child or adolescent." In a statement, the American Academy of Pediatrics (AAP) said thousands of boys and girls take part in the sport in North America, despite risks of serious brain and facial injuries. The group's position was approved by some experts. "There is very little one can do in order to increase the chance of having a healthy brain when you get old," said Dr. Hans Forstl, who has studied boxing injuries. " One of the best things you can do is avoid boxing." He said. According to the new statement, published in the journal Pediatrics, information from Canada shows a rise in boxing injuries over the past decade. Pat Russo, a retired police officer who runs a boxing gym in Brooklyn, New York, said injuries are rare in amateur boxing. After 26 years and training thousands of kids, he has seen just one split lip among his students. " If the gym is run properly, injuries are at an absolute minimum," Russo said. "Football is ten times more dangerous. While tennis or football might also help kids gain confidence, boxing holds a special attraction for children in poor neighborhoods, because it allows them to act tough while in trouble." Dr. Robert Cantu, a surgeon at Emerson Hospital in Concord, Massachusetts, said AAP's attitude makes sense for upper-class and middle-class kids. " Clearly boxing is safer today than it was 20 or 30 years ago, but it is still a very risky activity," he said. "For kids in poor areas, however, the situation is different," said Cantu. " The most dangerous thing for the majority of people in boxing is just where they live. They are far safer in the ring , even taking blows to the head, than they are out in the neighborhood." What is the text mainly about? A) The development of boxing gyms B) Children's risk of injury in boxing C) The disadvantage of doing boxing D) Measures to improve boxing safety

Q: Many jokes are made up about famous people. Here is one about Bill Clinton, the former president of the United States. Hillary died and went to heaven. When she was met by the Angel Gabriel she noticed behind her a wall of unimaginable proportions that was completely covered with clocks.

See that one?" the angel pointed to one that hadn't moved at all, "That's Mother Theresa's, who has never told a lie. And that one, " he points to another, "That was Abraham Lincoln's. He only ever told two lies. " Hillary looked around with some interest, then wandered back over to the angel again.

Question: Many expensive nutrition additives advertised on TV say they can improve your memory. But only ordinary food and healthy habits have been shown to work. A research team from UCLA (University of California at Los Angeles) has designed a four-step plan to improve your memory in just 14 days. "It sounds like another advertisement, but it really works," says UCLA psychiatry professor Gary Small. The team found the four-step plan improved memory function in teenagers under stress and older people. After a two-week study that included brain-teasers , exercise and diet changes, test subjects' memories worked more efficiently. Here's the programme: Memory training: Train yourself with brain-teasers, crossword puzzles and memory exercises that train verbal skills throughout the day. Healthy diet: Eat five rather than three meals a day. The food should be rich in omega-3 fats (omega-3), such as whole grains and vegetables that contain antioxidants . Having frequent meals helps increase blood glucose , the primary energy source for the brain. Physical fitness: Have regular physical exercise such as walking, basketball or running, every day. Stress reduction : Perform stretching and relaxation exercises. Stress causes the body to release a chemical that can shrink the memory centres in the brain. Before-and-after brain scans showed that test subjects experienced on average a 5 per cent increase in working memory. This suggests they were using their brains more efficiently. They also performed better on a cognitive test. A control group that didn't follow the plan showed no big changes. "We've known for years that diet and exercise can help people keep their physical health, which is a key part of healthy aging," said Small. "But keeping mental health is just as important. Now we have evidence that people can improve their memories through a programme of memory exercises and stress reduction." A research team from UCLA started the programme with the purpose of _ . A) improving your memory by eating healthy food in just 14 days B) advertising nutrition additives on TV C) proving many nutrition additive advertisement are false D) showing the relationship between memories and memory exercises
