Question: Article: Podcasting is like radio broadcasting, except that it uses the Internet. Anyone with a computer and a microphone can record a show about any subject. Anyone with a computer and an MP3 player can download the podcasts  and listen. Podcasting does require some technical knowledge, but not very much. Many education-related podcasts are aimed at college students. But a growing number is created for, and by, students in middle school and high school. At mountain View Alternative High School in prefix = st1 /Centreville,Virginia, the students have spent several weeks preparing for their project. They have written their stories. And they have recorded music and other sound to use in their podcasts. Next, they bring together the different elements on a computer. Their teachers help by offering comments and suggestions. The students have made decisions about how to present their information. They have decided how it will be read, and how other sound will be used. Some students decide to read their story themselves.

Question: Article: To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn't a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater. "Planting tress is one way, but it isn't that simple. It doesn't solve the basic issue of water resources," says Wu Bo, a professor. "We need to calculate how much water the trees will absorb, or else it could have a negative effect." Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields  using flood irrigation and earns a good income for his family. Other farmers haven't stuck it out : about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return. Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight. "With enough water, this problem can be solved," Lu says. "We can plant trees and grass, and they will grow bigger. That will stop the desert." Experts say that farmers could switch to drip irrigation  to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to "Save Water, Protect the Environment". 
 Answer: it can make groundwater become less

Answer: The negative effect of planting trees in deserts is that   _  .


Question: Article: "Dr.Papaderos, what is the meaning of life?" The usual laughter followed, and people stirred to go.Dr.Papaderos held up his hands and stilled the room and looked at me for a long time, asking with his eyes if I was serious and seeing from my eyes that I was. "I will answer your question." Taking his wallet out of his hip pocket, he fished into a leather wallet and brought out a very small round mirror, about the size of a quarter.And what he said went like this: "When I was a small child during the war, we were very poor and we lived in a remote village.One day, on the road, I found the broken pieces of a mirror.A German motorcycle had been broken in that place. I tried to find all the pieces and put them together, but it was not possible, so I kept only the largest piece.This one.and, by scratching it on a stone, I made it round.I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine--n deep holes and crevices and dark closets.It became a game for me to get light into the most inaccessible places I could find. I kept the little mirror, and, as I went about my growing up, I would take it out in spare time and continue the challenge of the game.As I became a man, I got to understand that this was not just a child's game but a metaphor for what I might do with my life.I came to understand that I was not the light or the source of light.But light--truth, understanding, knowledge--is there, and it will shine in many dark places only if I reflect it. I am a fragment of a mirror whose whole design and shape I do not know.Nevertheless, with what I have I can reflect light into the dark places of this world--into the black places in the hearts of men--and change some things in some people.Perhaps others may see and do likewise.This is what I am talking about.This is the meaning of my life.
