Section A

Pasta is no longer off the menu, after a new review of studies suggested that the carbohydrate can form part of a healthy diet, and even help people lose weight. For years, nutritionists have recommended that pasta be kept to a 26 , to cut calories, prevent fat build-up and stop blood sugar 27 up.

The low-carbohydrate food movement gave birth to such diets as the Atkins, Paleo and Keto, which advised swapping foods like bread, pasta and potatoes for vegetables, fish and meat. More recently the trend of swapping spaghetti for vegetables has been 28 by clean-eating experts.

But now a 29 review and analysis of 30 studies by Canadian researchers found that not only does pasta not cause weight gain, but three meals a week can help people drop more than half a kilogram over four months. The reviewers found that pasta had been unfairly demonized because it had been 30 in with other, more fat-promoting carbohydrates.

“The study found that pasta didn’t 31 to weight gain or increase in body fat,” said lead author Dr John Sievenpiper. “In 32 the evidence, we can now say with some confidence that pasta does not have an 33 effect on body weight outcomes when it is consumed as part of a healthy dietary pattern.” In fact, analysis actually showed a small weight loss. So 34 to concerns, perhaps pasta can be part of a healthy diet.

Those involved in the 35 trails on average ate 3.3 servings of pasta a week instead of other carbohydrates, one serving equaling around half a cup. They lost around half a kilogram over an average follow-up of 12 weeks.

Section B

Questions 46 to 50 are based on the following passage

Professor Stephen Hawking has warned that the creation of powerful artificial intelligence (AI) will be “either the best, or the worst thing, ever to happen to humanity”, and praised the creation of an academic institute dedicated to researching the future of intelligence as “crucial to the future of our civilization and our species.”

Hawking was speaking at the opening of the Leverhulme Centre for the Future of Intelligence (LCFI) at Cambridge University, a multi-disciplinary institute that will attempt to tackle some of the open-ended questions raised by the rapid pace of development in AI research. “We spend a great deal of time studying history,” Hawking said, “which, let’s face it, is mostly the history of stupidity. So it’s a welcome change that people are studying instead the future of intelligence.”

While the world-renowned physicist has often been cautious about AI, raising concerns that humanity could be the architect of its own destruction if it creates a super-intelligence with a will of its own, he was also quick to highlight the positives that AI research can bring. “The potential benefits of creating intelligence are huge,” he said. “We cannot predict what we might achieve when our own minds are amplified by AI. Perhaps with the tools of this new technological revolution, we will be able to undo some of the damage done to the natural world by the last one – industrialization. And surely we will aim to finally eradicate disease

and poverty. And every aspect of our lives will be transformed. In short, success in creating AI could be the biggest event in the history of our civilization.”

Huw Price, the centre’s academic director and the Bertrand Russell professor of philosophy at Cambridge University, where Hawking is also an academic, said that the centre came about partially as a result of the university’s Centre for Existential Risk. That institute examined a wider range of potential problems or humanity, while the LCFI has a narrow focus.

AI pioneer Margaret Boden, professor of cognitive science at the University of Sussex, praised the progress of such discussions. As recently as 2009, she said, the topic wasn’t taken seriously, even among AI researchers. “AI is hugely exciting,” she said, “but it has limitations, which present grace dangers given uncritical use.”

The academic community is not alone in warning about the potential dangers of AI as well as the potential benefits. A number of pioneers from the technology industry, most famously the entrepreneur Elon Musk, have also expressed their concerns about the damage that a super-intelligent AI could do to humanity.

Question 51 to 55 are based on the following passage.

The market for products designed specifically for older adults could reach $30 billion by next year, and startups(初创公司)want in on the action. What they sometimes lack is feedback from the people who they hope will use their products. So Brookdale, the country’s largest

owner of retirement communication, has been inviting a few select entrepreneurs just to move in for a few days, show off their products and hear what the residents have to say.

That’s what brought Dayle Rodriguez, 28, all the way from England to the dining room of Brookdale South Bay in Torrance, California. Rodriguez is the community and marketing manager for a company called Sentab. The startup’s product, Sentab TV, enables older adults who may not be comfortable with computers to access email, video chat and social media using just their televisions and a remote control.

“It’s nothing new, it’s nothing too complicated and it’s natural because lots of people have TV remotes,” says Rodriguez.

But none of that is the topic of conversation in the Brookdale dining room. Instead, Rodriguez solicits residents’ advice on what he should get on his cheeseburger and how he should spend the afternoon. Playing cards was on the agenda, as well as learning to play mahjong(麻将).

Rodriguez says it’s important that residents here don’t feel like he’s selling them something. “I’ve had more feedback in a passive approach,” he says. “Playing pool, playing cards, having dinner, having lunch,” all work better “than going through a survey of questions. When they get to know me and to trust me, knowing for sure I’m not selling them something – there’ll be more honest feedback from them.”

Rodriguez is just the seventh entrepreneur to move into one of Brookdale’s 1,100 senior living communities. Other new products in the program have included a kind of full-body blow dryer and specially designed clothing that allows people with disabilities to dress and undress themselves.

Mary Lou Busch, 93, agreed to try the Sentab system. She tells Rodriguez that it might be good for someone, but not for her.

“I have the computer and Face Time, which I talk with my family on,” she explains. She also has an iPad and a smartphone. “So I do pretty much everything I need to do.”

To be fair, if Rodriguez had wanted feedback from some more technophobic(害怕技术的) seniors, he might have ended up in the wrong Brookdale community. This one is located in the heart of Southern California’s aerospace corridor. Many residents have backgrounds in engineering, business and academic circles.

But Rodriguez says he’s still learning something important by moving into this Brookdale community: “People are more tech-proficient than we thought.”

And besides, where else would he learn to play mahjong?
