I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago．While any of these statements might be true, they are practically impossible to prove scientifically．Still, I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s．In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.

　　Why are America's kids so stressed? The report cites two main causes: increasing physical isolation -- brought on by high divorce rates and less involvement in community, among other things -- and a growing perception that the world is a more dangerous place.

　　Given that we can't turn the clock back, adults can still do plenty to help the next generation cope.

　　At the top of the list is nurturing （培育） a better appreciation of the limits of individualism．No child is an island．Strengthening social ties helps build communities and protect individuals against stress.

　　To help kids build stronger connections with others, you can pull the plug on TVs and computers．Your family will thank you later．They will have more time for face-to-face relationships, and they will get more sleep.

　　Limit the amount of virtual （虚拟的） violence your children are exposed to．It's not just video games and movies; children see a lot of murder and crime on the local news.

　　Keep your expectations for your children reasonable．Many highly successful people never attended Harvard or Yale.

　　Make exercise part of your daily routine．It will help you cope with your own anxieties and provide a good model for your kids．Sometimes anxiety is unavoidable．But it doesn't have to ruin your life.

1．What does the author mean when he says, "we can't turn the clock back" （Line 1, Para．3）?

A．It's impossible to slow down the pace of change.

B．The social reality children are facing cannot be changed.

C．Lessons learned from the past should not be forgotten.

D．It's impossible to forget the past.

A．were less isolated physically B．were probably less self-centered

C．probably suffered less from anxiety D．were considered less individualistic

3．The first and most important thing parents should do to help their children is ____.

A．to provide them with a safer environment

B．to lower their expectations for them

C．to get them more involved socially

A．Anxiety, though unavoidable, can be coped with.

Modern inventions have speeded up people’s lives amazingly．Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed．Indeed, this love of speed seems never-ending．Every year motor-cars are produced which go even faster and each new computer boasts （吹嘘） of saving precious seconds in handling tasks．

All this saves time, but at a price．When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so．We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind in another time zone．Again, spending too long at computers results in painful wrists and fingers．Mobile phones also have their dangers, according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about．

However, what do we do with the time we have saved? Certainly not relax, or so it seems．We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time．Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world．

There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle．No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern．There is much that we might envy about a way of life like this．Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone．Modern machinery has freed people from that primitive existence．

1．The new products become more and more time-saving because ．

A．time is limited B．our love of speed seems never-ending

C．the prices are increasingly high D．the manufacturers boast a lot

2．What does “the days” in Paragraph 3 refer to?

A．Simple life in the past． B．Imaginary life．

C．Times of inventions． D．Time for constant activity．

3．What is the author’s attitude towards the modern technology?

A．Objective． B．Critical． C．Optimistic． D．Negative．

4．What does the passage mainly discuss?

A．Machinery and human beings． B．The present and past times．

C．Imaginations and inventions． D．Modern technology and its influence．
