Article: As we all know, the Dragon Boat Festival is our country's traditional festival, but do you know there is also a Dragon Boat Festival in South Korea, which also falls on May 5 of the luar calendar ? It has been reported that South Korea will apply to United Nations Educational, Scientific and Cultural Organization (UNESCO ) to make the celebration of the Dragon Boat Festival its own intangible cultural heritage . If successful, people from other countries may see the Dragon Festival as a Korean creation. As the birthplace of the yearly event more than 2,000 years ago, China is not happy with the situation. "It would be a shame if another country successfully made a traditional Chinese festival part of its own cultural heritage ahead of China," said Zhou Heping, deputy culture minister. The Ministry of Culture is even thinking of making its own application to UNESCO, covering all traditional Chinese festivals, including the Dragon Boat event. It is thought that the festival is held in memory of the great poet Qu Yuan (340-278 BC), who lived in the State of Chu during the Warring States Period. Qu was known to be a patriot and admired by ordinary people. He is said to have jumped into Miluo River, because he had lost hope in his country's future. When people heard about Qu's death, they sailed up and down the river searching for his body. They also beat the drums to frighten away the fish and threw Zongzi into the water to stop the fish touching Qu. Dragon boat racing is said to come from this search for the poet's body. Over the years, the Dragon Boat Festival has spread throughout the world. In Japan and Viet Nam, as well as South Korea, the festival has mixed with and become part of the local culture. Question: What is the purpose of the Dragon Boat Festival's being held? - In memory of Qu Yuan - In memory of all the patriots of China - To frighten away the fish - In honor of QuYuan's birthday
In memory of Qu Yuan

Q: Read the following article and select the best answer. Article: Daniel Anderson, a famous psychologist, believes it's important to distinguish television's influences on children from those of the family. We tend to blame TV, he says, for problems it doesn't really cause, overlooking our own roles in shaping children's minds. One traditional belief about television is that it reduces a child's ability to think and to understand the world. While watching TV, children do not merely absorb words and images . Instead, they learn both explicit and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room. Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn't take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents' educational background have a stronger influence on a child's reading. "A child's reading ability is best predicted by how much a parent reads." Anderson says. Traditional wisdom also has it that heavy television-watching lowers IQ scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it's the other way around. "If you're smart young, you'll watch less TV when you're older," Anderson says. Yet, people of lower IQ tend to be lifelong television viewers. For years researchers have attempted to show that television is dangerous to children. However, by showing that television promotes none of the dangerous effects as conventionally believed, Anderson suggests that television cannot be condemned without considering other influences. Question: What is the main purpose of the passage? - To advise on the educational use of TV. - To describe TV's harmful effects on children. - To explain traditional views on TV influences. - To present Anderson's unconventional ideas.
A: To present Anderson's unconventional ideas.

Read the following article and select the best answer. Article: A camera and a computer can "see" something that perhaps millions of pairs of eyes failed to see for 480 years: the Mona Lisa's necklace. The discovery about the famous painting was made by an American physicist. The Mona Lisa, painted by the Italian, Leonardo da Vinci, has been on show for many years in Paris. Now a row of white spots on the neck have been "seen". They are said to be the remains of a necklace which the artist later painted over. The painting will be examined further by using infrared scanning techniques. Laser technology can be used to show what lies directly under the surface of the finished work, too. This will help us to understand how the artist drew the picture: Did he begin with a quick-made drawing or have second thoughts as he painted the picture? This kind of knowledge will show us the famous artist at work. It may also help to explain Mona Lisa's smile, which has puzzled art lovers for centuries. Question: This passage is mainly about _ . - the famous artist Leonardo da Vinci - an American physicist's discovery - further researches on the Mona Lisa - The uses of modern technology
(Answer)
further researches on the Mona Lisa
