We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running, for example, may help to protect you 1. heart disease and other health problems. Running also may help you live 2. (long)．

Recently, researchers studied more than 55,000 adults. About one fourth of the adults reported running 3. (regular). The study found these runners were considerably less likely than non­runners 4. (die) of any form of disease, including heart disease.

D.C. Lee and the other researchers found that speed, 5. (distant) and how often one runs made little difference in 6. (reduce) the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr. Lee says slower runners, and those who only ran once 7. twice a week, were helped nearly as much as those who ran faster and further.

The researchers note that their study 8. (base) on the participants’ answering questions over the years. The study lacked complete information on 9. these men and women ate and other facts about their lifestyles.

Researchers say this missing information could have affected the results. Still, they hope their findings will motivate healthy adults to start running down the road to 10. longer life.

Cycling or even walking in city areas can be a little dangerous, thanks to the fact that one is sharing the road with vehicles that are increasingly getting larger and heavier. A recent study proves that of the 1.27million people that die in road traffic crashes each year, about half are walkers, motorcyclists and cyclists. Now there may be a solution that could provide at least some help to protect this helpless group---an airbag!

If you are worried that this safety measure will involve you taking around a heavy package or worse still, wrapping yourself inside an ugly plastic bag, the bag is fitted not on the human, but on the outside of the vehicle. And, while there are several versions of the idea in the works, the one most recently unveiled by Dutch car company TNO, seems to be the most advanced and ready to go into production.

In the works since 2011, the airbag covers only the lower part of the windshield. This will provide the much needed buffer(缓冲)between the person’s head and the pane of glass he/she would otherwise meet.

The chain of events leading to an airbag cause are quite simple---A camera fitted beneath the rear-view mirror monitors the vehicle’s closeness to a walker or cyclist. Any contact with either one of them sets off the sensors in the car’s bumper and quickly blows up the airbag. In addition to that the sensors also set off the car’s automatic brake, reducing the chances if an even worse injury.

In tests conducted using a model, the success of not getting injured after being hit by a car travelling at about 40km/h was about 50-50! While not perfect, it will still result in reducing the number of deaths by a huge amount.

With TNO ready to license its technology to car makers and many more companies trying to develop similar concepts, we would not be surprised if outer airbags become a standard feature in every car pretty soon.

1.Why does the airbag cover the lower part of the windshield?

A. To protect the windshield from being destroyed.

B. To make the vehicle look beautiful.

C. To reduce the weight of walkers.

D. To prevent people’s head crashing on the glass.

2.The fourth paragraph is mainly about__________.

A. how the airbag works

B. where the airbag is fixed

C. why the airbag is safe

D. what the airbag is made up of

3.The writer thinks the airbag of TNO____________.

A. perfect

B. practical

C. expensive

D. useless

4.What is the main idea of the passage?

A. Airbags are a new standard feature in cars.

B. Airbags are much safer for drivers now.

C. Airbags are practical for walkers and cyclists.

D. Airbags are a solution to higher car accident rates.
