My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: “What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?”
He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation(创新) is incredible (难以置信的). We’re on a more different curve than we used to be.
One thing I’m looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you’ll be able to sample things before you buy them. But the question will be how I find what I’m looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded (具有相似目的), with whom I might really want to communicate? I want to find those people but it’s hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It’s going to be very interesting, I think.

New evidence shows that getting enough Vitamin D may be the most important thing you can do for your health.
You know the usual prescription for good health: a balanced diet with lots of fruits and vegetables, regular exercise, no smoking.Now add this: Spend a little more time in the sun.
Huh? That may sound like medical heresy (反面观点).After all, we've been warned for decades about the dangers of the sun: wrinkles, age spots and the increasing threat of skin cancer.But new and impressive medical evidence suggests that sunlight is beneficial.The vitamin D it prompts our bodies to make may prevent cancer, protect against heart disease and ward off a long list of disorders such as multiple sclerosis, rheumatoid arthritis, diabetes and gum disease.It is even showing promise as a treatment for heart disease and some cancers.
Long recognized as vitally important for bone building (it's needed for calcium absorption), vitamin D has now achieved superstar status among nutrients.While all doctors may not agree, many experts are confident enough of its wide-ranging powers to urge that we get much more of it, from the sun and from supplements, as even the best diet in the world may not give us enough.
Which of the following is NOT the usual way of keeping healthy?
A.To do exercise now and then.
B.To eat plenty of fruits and vegetables.
C.To avoid staying in the sun for a long time.
D.To keep away from cigarettes.
