[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: My first visit to London was one and a half years ago. It was a wonderful trip. I stayed in the city for three weeks, and I had many impressions. I visited all the famous places. I'd like to tell you about some of the places I visited in this beautiful city. First, I went to the Tower of London, and I want to say that it is a very interesting historical place. I found out that a long time ago, it was a prison. Later it became a castle for the royal family. Or maybe it is the reverse; I'm not sure, but later they left this place and lived in Buckingham Palace and Kensington Palace. I also enjoyed visiting the House of Parliament and Westminster Abbey, two very popular places for tourists. They are very old and beautiful. The Abbey is built in a kind of Gothic style; it is fantastic. In London, you can also enjoy nature. There are many parks such as Hyde Park, Green Park, and Holland Park. These parks are wonderful green, quiet places where you can relax and escape the noise of the city. Trafalgar Square is a popular place for students and other young people. You will find lots of pigeons there. If you have time, you can feed them and they will be very happy. You can buy special food for them, but be careful! Tons of birds are going to surround you if you feed them. Another very special place in London that I like is St. Paul's Cathedral which was designed by Sir Christopher Wren. I also was impressed with the museums in London. They're very popular. I found them interesting because you can learn about the history of England. I had a wonderful time in London. I really liked it because it is a city that is rich in history.

[Q]: Article: According to some researchers, you should not praise children for everything that they do. It does not help them build self-confidence. Most parents and teachers agree that praise can help increase children's self-confidence --the more, the better. However, according to some researchers, only proper praise is good for children. If adults praise everything children do, it makes children look for praise all the time, not trying to do their best. "Teachers should not say things like 'good job' or 'nice work' whenever a child does anything. They should encourage them to continue to improve," some researchers advise. Another idea is that children with high self-confidence are happier, and do better at school. About this, Marshall Duke, a researcher in children, says, "High self-confidence brought in by too much praise does not make children happier, get more, or become able to do more. Finding a child's advantages and developing them can help build confidence more than too much praise can." Praise also loses its effect if it is given equally to all students. "It's important to tell children the truth about what they've done. Honest feedback is far better than empty praise," Duke adds. "People have got into the habit of not telling children when they're wrong. That makes it hard for them to deal with difficulties when they grow up. That's just how the world is."
