For years, experts have been encouraging people to exercise, using steps as simple as taking the stairs instead of a lift and walking to work, where possible. A recent study bolsters this advice — it shows that frequent active exercise throughout the day can have great health benefits.

The study, published in the magazine Preventive Medicine, found that just 2 minutes of stair-climbing several times a day can lower total cholesterol(膽固醇), raise HDL (“good”) cholesterol and improve the heartbeat in young women who do not have much activity during the day.“such improvements may have important effects on the health of women, since, like cigarette smoking, poor fitness have been shown to be a high risk for heart disease and death in women,”said Dr.Colin Boreham with the University of Ulster in Belfast, Ireland and the fellow researchers of this study group. Furthermore, improvements in total cholesterol levels achieved in the study could cut the rate of heart disease in women by a third, they noted.

The team of researchers from Britain studied 12 women between 18-22 years old, before and after the exercise program. The women used a public staircase for about 2 minutes a day for 5 days a week. Compared with a group of 10 women who did not take part in the stair-climbing program, the women who climbed stairs showed marked improvements in health and fitness levels after 7 weeks. However, they did not show any signs of weight loss.“A short-term stair-climbing program can give great health benefits to young women. Stair-climbing may be a particularly suitable way of combining exercise with an individual’s daily lifestyle,”they pointed out.

Experts advise visiting your doctor before beginning a new exercise program.

The Hunan Satellite TV(HNTV) show Where are we going,Dad? is a big hit.Many famous stars brought their children to a strange village alone,and they had to spend 72 hours with their children there.The program fully showed us a modern version of the “how to be a good father”.As the young parents today are too busy to take care of their children,this new form of “Lost on the way” played by nanny(保姆式的) daddy and cute kids triggered(觸發(fā))a lot of people’s emotional resonance(共鳴).Both the kids and their parents will find that their hearts are being drawn closer.But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.

The TV shows like Children are hard to support!,Where are we going,Dad?,Hot Mom and Cute Kids are becoming more and more popular.All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.

In real life,on the one hand,the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life;on the other hand,they continue to do so.The data collected by HNTV show that nearly two-thirds of their audience are female,among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children,while her husband is still at work or trapped in socializing,or maybe is just playing computer games in the bedroom.The story of a child without the company of father is still going on.In fact,it is sometimes the same to mothers.In a modern family,it is often the old who take the responsibility for raising a child.The participation of mother in the children’s education is also very low.

It is just this kind of confusion where the parents have gone in the modern family education,and where the parents will guide their children to go that Where are we going,Dad?shows us.If a child wants to grow up healthily and safely with independent personality and free spirit,it is very important for him or her to follow the parents who serve as their first teacher.Maybe this is the real reason why such kind of TV programs could get hot.The truth is that children will go where their parents go,and society will go where the children go.

1.Which of the following can be inferred from the passage?

A.Parents shouldn’t entirely leave the education of children to the old.

B.36% of the audience of the program are female aged from 25-34.

C.The program shows us the confusion where the parents and children will go to play.

D.In a modern family it is often mothers who are responsible for raising a child.

2.In raising a child in modern society,parents should .

A.play computer games with their children

B.break down the barrier between children and teachers

C.balance well between family and career

D.keep their children at home to avoid socializing

3.What attitude towards modern family education does the author express in the passage?

A.Optimistic. B.Proud.

C.Negative. D.Worried.

4.Which one is the best title of the passage?

A.Confusion behind Where are we going,Dad?

B.Modern Education is Important

C.Nanny Daddy and Cute Kids

D.New Problems in Modern Children’s Education
