Read the article and select the best answer. Article: Farmers, especially in developing countries, are often criticized for cutting down forests. But a new study suggests that many farmers recognize the value of keeping trees. Researchers using satellite images found at least ten percent tree cover on more than one billion hectares of farmland. That is almost half the farmland in the world. Earlier estimates were much lower but incomplete. The authors of the new study say it may still underestimate the true extent worldwide. The study found the most tree cover in South America. Next comes Africa south of the Sahara, followed by Southeast Asia. North Africa and West Asia have the least. The study found that climate conditions alone could not explain the amount of tree cover in different areas. Nor could the size of nearby populations, meaning people and trees can live together. There are areas with few trees but also few people, and areas with many trees and many people. The findings suggest that things like land rights, markets or government policies can influence tree planting and protection. Dennis Garrity, who heads the World Agroforestry Center, says farmers are acting on their own to protect and plant trees. The problem, he says, is that policy makers and planners have been slow to recognize this and to support such efforts. The satellite images may not show what the farmers are using the trees for, but trees provide nuts, fruit, wood and other products. They also help prevent soil loss and protect water supplies. Even under drought conditions, trees can often provide food and a way to earn money until the next growing season. Some trees act as natural fertilizers. They take nitrogen out of the air and put it in the soil. Scientists at the Center say the use of fertilizer trees can re-duce the need for chemical nitrogen by up to three-fourths. Trees also capture carbon dioxide, a gas linked to climate change. Question: Through the study, the researchers found that _ Options: A: there are more trees on farmlands than expected B: fewer trees are being cut in developing countries C: most farmers still don't realize the value of trees D: trees play a key role in preventing climate change

Q: Read the article and select the best answer. Article: Some young Cambodians are learning a new sport -- skateboarding. The country's first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital. Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea, who has been skating for 6 months, says skating has already become his favorite sport. The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards. A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. Skateistan started its work in Afghanistan years ago. Rory Burke is working with the group which expanded to Cambodia last year. Rory Burke points out, "Yeah, it's definitely not a typical Cambodian pastime . And I think the idea of 'why skateboarding' is that it's not been done before here. We want to use skateboarding as something saying, 'Hey, this is new, this is something different.And that kind of itself becomes _ . People see it and they think and they say, 'Wow, what is that?' and they want to get involved. " Skateistan partners with local groups that work with young people. The park is on the grounds of the group known as PSE, where children attend school and learn a trade. There are almost one hundred twenty participants. They all come from troubled lives. Seventeen-year-old Sang Rotha is a student at PSE. "Sometimes I don't do well in subjects like math," he says, "I feel bad when I find it hard to keep up with my lessons. So that is why I skateboard ---to improve my bad feelings. ', He says he began skateboarding more than a year ago. Before he started training, it seemed very easy. But it was very difficult to learn tricks, and he got hurt a lot from falling off. Rory Burke says learning to deal with the difficulties is part of the lesson for these young skateboarders. Question: It can be inferred from the passage that skateboarding is becoming _ . Options: A: a sport liked by most young Cambodians B: an increasingly popular sport in Cambodia C: a sport used to better young Cambodians' life D: a good way to train young Cambodians' learning skills
A: C

In 1903 when Einstein was 24, he married Merits, who was 4 years older than he. After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Merits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home. In1914, Einstein moved to Berlin and _ there. At that time his theory proved to be correct and he had become famous all over the world. But it was not long before the First Would War broke out. Merits as well as her two sons, who were on holiday in Switzerland, couldn't come back to Berlin any more. The war not only stopped Einstein's work but also broke up the warm, happy family. In 1919, Einstein and Merits had to get divorced . Question: In which year was Merits born? _ Options: A: 1896 B: 1875 C: 1883 D: 1879
