Are you wondering whether it’s worth going for a little jog? Don’t hesitate, and get your sports shoes on. A new study shows that proper running lowers the risk of death before the normal time.
In a survey of 14 previous studies from the US and Denmark, the group of researchers from institutes in Australia and Finland concluded that running would probably lead to improvements in population health and longevity（长寿）.The studies involved 232,149 participants over time periods ranging from 5. 5 to 35 years.
On the whole, people running any distance were related with a 27% lower risk of death from all causes than those who did not, the study shows. Running was also related with a 30% and 23% lower risk of death from cardiovascular（心血管的）disease and cancer.
Previous studies had concluded “inconsistent findings” about whether running could lower the risk of death before the normal time, according to the researchers. Lead researcher Jim White, a professor at Victoria University in Melbourne, told CNN: “Our recent findings may encourage physically inactive individuals to take up running and those who already run to keep on doing it.”
He added that doctors may be encouraged by our findings to promote running as a part of “lifestyle medicine”. In their paper, which will be published in the British Journal of Sports Medicine, the researchers say health professionals are sometimes wary of promoting running because vigorous（剧烈的）use of it has been linked with sudden heart death.
Jim and his team deny this by noting that the benefit of running outweighs the risk. However, they did say advice should be given on a case — by — case basis, as running might not be appropriate for everyone. Although running has a clear health benefit, the researchers point out that higher “doses” of running may not reduce the risk of death further. According to the WHO s guidelines, adults aged between 18 and 64 should take 150 minutes of gentle exercise or 75 minutes of vigorous exercise each week.

C.People’s living conditions. D.The popularity of jog.
2.What will the study contribute to according to Jim?
A.Doctors’ quicker treatment. B.People’s losing weight.
C.People’s involvement in running. D.Researchers’ promotion of sport.
3.What does the underlined word "wary" in paragraph 5 mean?
A.Certain. B.Tired.
C.Cautious. D.Confident.
Can robots be creative? British art gallery owner Aidan Meller thinks so. He hopes to begin answering that question with a robot called Ai-Da. Meller is watching the building of all Ai-Da’s parts by engineers at Engineered Arts, a company based in Cornwall, England. The engineers believe the robot will be able to make pictures of people from sight with a writing instrument in her hand. Meller wants the robot to perform like a human artist.
After seeing Ai-Da’s head being carefully brought to life by specialists who were connecting individual hairs to form eyebrows, Meller said, “She’s going to actually be drawing and we’re hoping to then build technology for her to paint.” But also as a performing artist, “she’ll be able to communicate with audiences and actually get messages across, asking those questions about technology today,” he added.
Ai-Da’s robotic head may still be separate from her body, but her movements are very alive. Cameras in each of her eyeballs recognize human body parts. Ai-Da will make eye contact and follow you around the room, opening and closing her mouth as you do. If you get too close, the robot will back away, closing and then opening her eyes as if in shock.
The specialists are using the company’s Mesmer lifelike robot technology to create her head. Once finished, Ai-Da will have a mixed-race appearance, with long dark hair and manmade skin. The teeth and skin inside her mouth will come from a 3-D printer. Marcus Hold works at Engineered Arts. He said Mesmer “brings together the development of software mechanics and electronics to produce a lifelike face with lifelike gestures in a small human sized package.”
Ai-Da will make her first public appearance at an exhibition called “Unsecured Futures” at the University of Oxford. Some of her pictures are expected to appear at another show in London later this year.
1.How will Ai-Da do when you get very close to her?
A.Keep still. B.Step back.
C.Run away. D.Speak aloud.
2.Which of the following is Ai-Da good at?
A.Taking care of the old. B.Communicating with persons.
C.Doing housework. D.Making up like humans.
3.What may be the best title for the text?
A.Ai-Da, a Creative Robot B.Meller, a Great Engineer
C.Ai-Da Makes Painting Easier D.Meller Helps Robot Cleverer
