Imagine a cat that does not need someone to clean up after it keeps an older people company and helps them remember to take their medicine. That is the shared dream of the toy maker Hasbro and scientists at Brown University in Providence, Rhode Island. The researchers received a $ 3-million-dollar from the National Science Foundation for a special project. They want to find ways to add artificial intelligence, or AI, to Hasbro’s “Joy for All” robotic cat.
The cat has already been for sale for two years. Though priced at over 1,000 dollars, it sold quite well. It was meant to act as a “companion”(陪伴) for older people. Now the project is aimed at developing additional abilities for the cat. Researchers are working to decide which activities older adults may need the most. They hope to make the cat perform a small number of activities very well. Such activities include finding lost objects and reminding the older people to take medicine or visit their doctor. They also want to keep the cost down to just a few hundred dollars.
It is an idea that has appealed (有吸引力) to Jeanne Elliott. Her 93-year-old mother Mary Derr lives with her in South Kingstown. Derr has dementia (痴呆). The Joy for All cat that Elliot bought this year has become a true companion for Derr. The cat stays with Derr and keeps her relaxed while Elliott is at work. Elliot said a robotic cat that helps her mother to remember to take her medicine and be careful when she walks would be greater.
The researchers are trying to learn how the improved cats will complete helpful activities and how they will communicate. They say that they do not want a talking cat, however. Instead they are trying to design a cat that can move its head in a special way to successfully communicate its message. In the end, they hope to create an exchange between the human and the cat in which the human feels the cat needs them. By doing so, the researchers hope they can even help prevent feelings of loneliness and sadness among elderly people.

Are you getting enough protein（蛋白质）? The question provides its own answer: If you are worrying about the amount of protein in your diet, then you are almost certainly eating more than enough.
You merely need to visit a western supermarket today to see that many people regard protein as some kind of excellent medicine — one food companies are profitably adding to anything they can. “When the Box says ‘Protein’, Shoppers say ‘I’ll take it’” was the headline of a 2013 article in The Wall Street Journal.
The intensity of our protein obsession can only be understood as part of a wider series of diet battles that go back half a century. If we now thirst for protein as if it were water, it may be because the other two macronutrients — fats and carbohydrates — have each in turn been made to seem poisonous (有毒的) in the public mind.
In the current nutrition wars, protein has emerged as the last macronutrient left standing. David L. Katz, an American doctor and public health scholar who is the director of the Yale-Griffin Prevention Research Center said, “First they told us to cut fat. But instead of whole grains and lentils, we ate low-fat junk food.” Then food marketers heard the message about cutting carbohydrates and sold us protein-enriched junk foods instead.
For decades now, there has been a tendency to think about what we eat and drink in terms of nutrients, rather than read whole ingredients in all their complexity. A combination of diet fads and clever marketing has got us here. It doesn’t matter whether we fixate on “low fat” or “low carbohydrates” or “high protein” — we are making the same old mistakes about nutrition in a new form.

Imagine a child standing on a diving board four feet high and asking himself the question: “Should I jump?” This is what motivation or the lack of it can do. Motivation and goal setting are the two sides of same coin. 1. Like the child on the diving board, you will stay undecided.
2. More than that, how should you stay motivated to achieve the goal? First, you need to evaluate yourself, your values, your strengths, your weaknesses, your achievements, your desires, etc. Only then should you set your goals.
You also need to judge the quality and depth of your motivation. This is quite important, because it is directly related to your commitment. There are times when your heart is not in your work. 3. So, slow down and think what you really want to do at that moment. Clarity(清晰) of thoughts can help you move forward.
Another way of setting realistic goals is to analyze your short and long term objectives, keeping in mind your beliefs, values and strengths. Remember that goals are flexible. 4. They also need to be measurable. You must keep these points in mind while setting your goals.
Your personal circumstances are equally important. For example, you may want to be a pilot but can’t become one because your eyesight is not good enough. 5.You should reassess your goals, and motivate yourself to set a fresh goal.
You will surely need to overcome some difficulties, some planned, but most unplanned. You cannot overcome them without ample motivation. Make sure that you plan for these difficulties at the time of setting your goals.
A. This can affect your work.
B. So how should you motivate yourself?
C. However, this should not discourage you.
D. So why should we try to set specific goals?
E. They can change according to circumstances.
F. Motivation is what you need most to do a good job.
G. Without motivation, you can neither set a goal nor reach it.
We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.
So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
1.What does the author think of new devices?
A.They are environment-friendly. B.They are no better than the old.
C.They cost more to use at home. D.They go out of style quickly.
2.Why did Babbitt's team conduct the research?
A.To reduce the cost of minerals.
B.To test the life cycle of a product.
C.To update consumers on new technology.
D.To find out electricity consumption of the devices.
3.Which of the following uses the least energy?
A.The box-set TV. B.The tablet.
C.The LCD TV. D.The desktop computer.
4.What does the text suggest people do about old electronic devices?
A.Stop using them. B.Take them apart.
C.Upgrade them. D.Recycle them.
