If you think that running marathons will help you live a long and healthy life，new research may come as a shock．According to a recent scientific study，people who do a very strenuous workout are as likely to die as people who do no exercise at all．

Scientists in Denmark have been studying over 1，000 joggers（慢跑者） and non-joggers for 12 years．The death rates（率） from the sample group suggest that people who jog at a moderate(适合的) pace two or three times a week for less than two and a half hours in total are least likely to die．

The best speed to jog at was found to be about 5 miles per hour．The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers．The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉)．Over time，this can cause serious injuries．

Peter Schnohr，a researcher in Copenhagen，said，“If your goal is to decrease（减少） risk of death and improve life expectancy，jogging a few times a week at a moderate pace is a good strategy（策略）．Anything more is not just unnecessary，and it may be harmful．”

The implications（含义） of this are that moderate forms of exercise such as tai chi，yoga and brisk walking may be better for us than “iron man” events，triathlons（三项全能） and long-distance running and cycling．According to Jacob Louis Marott，another researcher in the study，“You don’t actually have to do that much to have a good impact（影响） on your health．And perhaps you shouldn’t actually do too much”．

1.The underlined word “strenuous” in Paragraph l is closest in meaning to“___________”．

A．hard　　　　　　　　 B．regular

C．practical　　　　　 D．flexible（灵活的）

2.The author presents some figures in Paragraph 2 to ___________．

A．suggest giving up jogging

B．show risks of doing sports

C．provide supportive evidence（证据）

D．introduce the research process（过程）

3.According to the scientists，why is too much exercise harmful？

A．It may injure the heart and arteries．

B．It can make the body tired out．

C．It will bring much pressure．

D．It consumes too much energy．

4.What can be inferred from the text？

A．No exercise at all is the best choice．

B．More exercise means a healthier life．

C．Marathons runners are least likely to die．

D．Proper exercise contributes to good health．

Maybelle said she wouldn't be coming with me to the library. I asked why, and she said she could get all the short stories she wanted off the Internet. Saved walking all the way to the library, and putting up with my long chat on the way there, and on the way back. Maybelle is very direct like that, always has been.

"But, Maybelle, we've been walking to the library every' Monday for the last fifty years!"

She said," Why don't you get Internet'? We can send each other emails."

So I had to get Internet. I called the local high school. They said they'd send me a good student to tell me all about computers and such.

Evil thing, this Internet. Makes you lose old friends, forces you to learn new complex ideas, even if you're too old. But Maybelle said you have to be modern; otherwise, you're dead.

The kid came the next day. Tall skinny black kid, by tile name of Arsenius, said his work would cost me.

I said, "All right. As long as I get Internet."

"You need a computer, then you need to get hooked up," he said.

"Let's buy a computer and get hooked up, then."

"How much you want to spend?"

"Whatever it takes."

"How many rams you want?"

I wasn't going to show him my ignorance, so I said, "Whatever it takes."

"Let's go to the mall. You got a car?"

"In the garage."

When I opened the garage door, he gasped. Daddy's car is still there, a'57 Chevy. I never drive it. Walk everywhere.

I said," Let's walk. It's only a mile or so."

He said," Let's drive, or you will faint on me in this heat."

"Young man, I don't faint, never have. We're walking."

"I get paid by the hour," he said. "Walking will cost you a lot more. Also, you feel like carrying a computer a mile or so?"

1.What kind of person is Maybelle?

2.Why does the writer want to have Internet at his place?

3.Arsenius gives _________ reasons for driving to the mall.
