Students at Empire High School started class with no text books-but it wasn't because of money problems.
Instead, the school gave iBbooks-laptop computers to each of its 340 students, becoming one of the first US public schools to stop printed textbooks.
School officials believe that the electronic materials will make students enjoy learning more Empire High School was designed to have a textbook-free environment.
Students at Empire High School get the materials over the school's Internet network. The school has a central control system that limits what can be downloaded at the school.
“Students can hand in homework online. We have a web program that helps to check if you copy from others,” the headmaster Baker said.

Like all big cities, Paris has a traffic problem: lots of cars. lots of traffic jams and lots of pollution from exhaust fumes(废气). So the city began a scheme(计划)to improve the situation.
Under the Velib scheme ('Velib' comes from velo liberte, or 'bicycle freedom') people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour-on the bike is free, but if you don't return it after 30 minutes, you have to pay. But it's only € 1 a day or € 29 a year! The bicycles are heavy (25kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!
Paris is not the first city to have a scheme like this. But not everybody thinks it's a great idea. One Parisian said. “These bicycles are only for short journeys. If people want to travel across the city, they won't use a bicycle-they'll still use their cars.”
A city spokesman said, “The bicycle scheme won't solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren't any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get worse. The bikes might help people to lead a healthier life, too. “

The science of physics today is as current as the morning newspaper. Indeed, as a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants,the world itself has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.
Clearly, every grown-up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美国国会)voting huge sums of money for warships, space exploration, or atomic energy; the office staff learning to use a new computers; Son Bobby wanting to know about going to the moon; or the housewife learning to operate a electric stove, physics seems to be everywhere.
Teachers in thousands of schoolrooms in America are trying to communicate some of the excitement and importance of these new developments to their students. They know that some of their eager student will someday be scientists and will themselves then contribute to the development of new knowledge or its application to new things.
But in any case, they can be sure that if they bring a knowledge of science (any science) to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.

Ali and his younger sister, Zahra, lived with their parents in a poor neighborhood. Their mother was very sick and their father was struggling to find a job, and they had only a little money with which to buy food. As they had not paid the rent for several months, the landlord was breathing down their necks(盯着他们).
One day, Ali took Zahra’s shoes to a shoe repairman to be fixed, but he lost them on the way home. It wasn’t until he got home that he realized he had lost the shoes. He was afraid that his parents would be angry and disappointed, so he begged his sister to keep it secret. Zahra agreed and the two decided to share Ali’s running shoes. Zahra’s school hours were in the morning, so she would wear them first. After school, she would rush back and give them to Ali. He could then run to his school, which began in the afternoon. Although he ran as fast as he could, Ali often arrived late and was warned by the school.
Ali heard about a long distance race that was held for the boys in the city. When he learned that the third prize was a new pair of shoes, he decided to take part. He ran home excitedly and promised his sister that he would win her the new shoes.
The day of race arrived. Ali had a strong start, but halfway through the race he began to get tired and his legs began to ache. Getting more and more exhausted he thought only of Zahra and his promise to her. Dreaming of the new shoes he would win for his sister gave him strength, and he stayed right behind the two fastest runners, determined to finish third. Suddenly, as the finish line drew near, another runner collided(碰撞) with Ali from behind and he crashed to the ground.
