[Q]: Article: A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001. American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa requirements. Now stronger efforts are being made to get more foreign students to study in the United States. China remained in second place in front of South Korea but behind India, whichsent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place. There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand. For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University. Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering. The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year.

[Q]: Article: Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can ensure their safety and well-being, although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students. The main reason for violence acts are the films and cartoons that fill the children's time. They want to do everything they watch on TV and never think of the consequences, and they may hurt a classmate or a teacher. On the other hand, parents are not fully satisfied with the children's results obtained in classes and they consider private classes would have better results. When a teacher has to watch 30 students in class he can't probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in details everything the child doesn't understand as many times as he considers proper. And many times the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear there might happen something bad to him only makes the child's character weak and prevents him from knowing what real life is. Staying in _ only does harm to the child. All in all, schools have been created to help children, not to harm them, so it's best to keep children in these special places, where they learn, laugh, have fun and make new friends
Answer: explain the main reason for violence acts in schools
[A]: The writer's purpose in writing the text is to _

[Q]: Article: Effective environmental protection laws and other measures have led to the improvement of water quality in Tai Hu lake in prefix = st1 /JiangsuProvince. The news was announced by officials from the provincial environmental protection bureau, which has just conducted an inspection of the lake area. By the end of September, about 80 per cent of industrial pollutants met required standards and the lake is expected to be cleaner by the end of the year, officials said. According to targets set by the State Environmental Protection Administration, all polluting enterprises must meet set standards by the end of this year or they will be shut down. The Taihu Lake area, which surrounds the cities of Suzhou, Wuxiand Changshou, is one of the most economically developed areas in the country and has long enjoyed a reputation as the "land of fish and rice" However, the quality of water in the lake has been deteriorating at an alarmingly rate in recent years, which has caused concern from the government and local people. Pollution is so high mainly because people do not have enough environmental awareness and have put economic benefits ahead of their surroundings. Economic development in the area has been rapid with hundreds of factories being built. But officials say most of these do not have the anti-pollution equipment or measures they should have. Because of the lack of waste treatment facilities, wasted water and other rubbish from residential areas in nearby towns and villages flow into rivers which are connected to TaihuLake. This also contributed to the lake's pollution. Realizing the seriousness of the situation, the provincial and local governments began to tackle the problem. Experts were invited to offer suggestions and laws and regulations were issued. All newly built factories and enterprises in the lake area were required to install necessary anti-pollution facilities before they can go into operation. Also, some wasted water treatment works will be built in the three cities.
