Kuss Middle School serves students in Fall River, Mass. , a former mill town that has struggled economically for decades. Students at Kuss have struggled, too, usually falling short of making the academic progress required under the No Child Left Behind law.

Then, last year, the school experimented with extending the school day. Teachers got paid at a higher hourly rate.

Students weren't thrilled at first with leaving school at 4:15 p.m. instead of at 2:20 p.m. But the added hours gave them more time for physical education and let them select special interest classes. By the end of the year, student scores had risen by enough to enable Kuss to make the progress required under the federal No Child Left Behind law.

The only surprise is that more districts haven't lengthened school schedules set decades ago to accommodate (适应) a farm economy rather the information economy of today.

New research suggests the time is ready for a change:

Matched against 39 other developed countries, the United States is near the bottom in the rankings of average weekly instructional time in school.  Measured over 12 years, students in the top-scoring countries spend the equivalent of a full extra year in school.

US students perform poorly on math and science tests compared to their international peers, according to a US Education Department comparison released earlier this month. In math, American 15-year-old scored near the bottom among the study's 30 developed countries.

Most countries that boost the number of minutes spent on math instruction find pay offs in improved math scores, according to a study released this month by the Brookings Institution. Small in creases in the school day are more effective than a longer school year, the report concluded.

The most encouraging news about the benefits of extending the school day comes from Massachusetts, where an experiment with 10 schools, including Kuss, appears to be working. Those 10 schools lengthened their instructional days by 25% and boosted their state scores in math, English and science at all grades.

Perhaps the concept won't work everywhere. Certainly, it won't instantly be popular. But it's obvious that a problem exists or that adding class time seems to help.

Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze(注视) of a pair of eyes. The surprise was that the eyes were not real, but photographed.

Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an-honesty box alongside a kettle ,with tea, coffee and milk. Over 10 weeks, they alternated each week between images of eyes and pictures of flowers.

Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. They effect may arise from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.

"If nobody is watching us it is in our interests to behave selfishly. But when we think we're being watched we should behave better, so people see us as co-operative and behave the same way towards us, "Dr. Bateson said.

"We thought we'd get a slight effect with eyes, but it was quite striking how much difference they made. Even at a subconscious(潜意识的) level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(进化) to respond to."

The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could promote ticket sales on public transport and improve monitor systems to prevent antisocial behavior.

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?

It was just getting dark. There was a touch of fog and I was on a lonely stretch of road.   36 I was going along cheerfully, thinking about the dinner I would eat when I got to Salistury .

I was going along   37 at about thirty-five miles an hour when suddenly I heard a scream, a  38 scream--- “ Help! ” I looked round, but the only   39 of life was a large, black, rather suspicious--looking（可疑的）car just   40  a bend in the road about a hundred yards away. That was where the cry had come from. I   41  speed and went after it. I think the driver saw what I was doing, for he did the same and began to draw   42  me. As I drew near, the girl’s voice came again, a lovely voice but trembling with   43  .

“Let me go, you coward; you’re hurting me. Oh ! Oh ! ”

I felt my   44  boil. The fog was coming down   45  now, and the countryside was lonelier. I had no  46 that the murderous guy in the car noticed this. Again came a cry.

“Drop that knife, you fool. Oh ! ” Then a cry and a groan（呻吟）.

If I was to save her, it was now or   47 . Perhaps even now I was too late. But if I couldn’t save the girl, I would at least try to bring the murderer to   48 . The car was only a couple of yards away now. I drove the bike right across its   49 , and its brakes（刹车）screamed as the driver tried to pull it over and  50  into the ditch（沟）at the side of the road. The door of the car was pushed open angrily and a dark, evil-looking fellow stepped out .

“You fool!” he shouted as he came towards me with his fist raised to hit me. But I was   51   than he. I put all I could into   52  that would have knocked out Joe Louis. It   53  him right on the point of the chin; his   54  slowly bent under him, and he dropped to the ground without a sound. I rushed to the car,   55  open the door and looked inside. There was no girl there. Suddenly from the back of the car came a voice.

“You have been listening to a radio play, Murder in Hollywood, with Mae Garbo and Clark Taylor. The news will follow immediately . ”
