Question: Read the following article and select the best answer. Article: A year ago, I paid no attention to English idioms, though my teacher emphasized  the importance again and again. But soon, the importance of English idioms was showed in an _ experience. One day, I happened to meet an Englishman, on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished, gently shaking his head ,shrugging  his shoulders, saying, "You don't say! You don't say!" I was puzzled, I thought, perhaps this is not a proper topic.Well, I had better change the topic. So I said to him, "Well, shall we talk about the Great Wall? By the way, have you ever been there?" "Certainly, everybody back home will laugh at me if I leave China without seeing it. It was magnificent(,)." He was deep in thought when I began to talk like a tourist guide. "The Great Wall is one of the wonders in the world. We are very proud of it. " Soon I was interrupted  again by his order "You don't say!" I couldn't help asking, "Why do you ask me not to talk about it?"  "Well, I didn't request you to do so," He answered, greatly surprised. I said, "Didn't you say you don't say?" Hearing this, the Englishman laughed to tears. He began to explain, "You don't say actually means really? It is an expression of surprise Perhaps you don't pay attention to English idioms" Only then did I know I had made a fool of myself. Since then I have been more careful with idiomatic expressions.

Read the following article and select the best answer. 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". Question: The negative effect of planting trees in deserts is that   _  . - it can make groundwater become less - it can prevent the sand moving freely - it can stop crops growing well - it can get the soil to become poor
it can make groundwater become less
