2 . As I enter my 40s, I’ve noticed many of my parents’ generation think social networking is something they are simply unable to understand. They fear that, should they try, they will somehow get it wrong; they will say the wrong thing, do the wrong thing or behave in a way that causes embarrassment. But there are some secrets of social media for them to consider.
Here’s the first secret: everyone feels this way. I recently met a young actor who was complaining that her work demands that she join Microblog, but she always feels like she doesn’t have anything smart to say. It’s the same resistance (抵制). I hear from the older generation, who, however, have somehow believed that age is the barrier (障碍), rather than the differences of personal taste.
Here’s the second secret: everybody uses it for more or less the same reasons. Older generations often sign up to stay in touch with children and relatives. We talk about this kind of communication like it’s some old-fashioned activity, but it is exactly why younger people use social media. The truth is that most people use social media to gently keep an eye on one another, to see how those they care about are doing without needing to ring them up on the phone every night.
And this is the last secret: everyone gets to use them in their own way. Newcomers—younger and older—who worry about “getting it right” are thinking that there’s a right way to get them. But actually there isn’t. Personally, I talk a lot on Microblog. And some people post nothing and they use social media every day as readers. Social media companies would rather see people decorating their networks with pictures and posts, but there’s no rule against being a fly on the wall. It’s also a fine way to get involved.
Were quick to forget that the web wasn’t invented by 13-year-olds; it was created by today’s seniors. I’d never try forcing those with no interest in social networks to use Microblog. But don’t let the talk of age divides put you off. There’s nothing to stop the older generation from joining in the network their own generation created.

Think of space，perhaps a permanent(永久的) station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed，permitting long journeys throughout the solar system(太阳系). When that time comes，people will be taking holidays in space and visiting other planets. Great progress will have been made in medicine，too. Perhaps a cure will have been discovered for the most terrible of all diseases—cancer. Pollution is a problem we must solve. In a hundred years’time it will have been controlled.
All the world will have been developed — even Antarctica. There will be large cities in Antarctica. We already have supersonic(超音速的) flight，but in a hundred years’time we will have supersonic land travel as well.
We will have used up most of earth’s land to build our cities， so floating cities will have been built. The Japanese already have plans for cities of this kind. And there will be cities under the sea. The first of these will have been completed.
