[EX Q]: Article: Every spring Beijing is choked by huge sandstorms.The sky turns a strange and frightening yellow colour as clouds of sand sweep down from the deserts of Mongolia and north-western China.Strong winds blow up the dust and cover everything in sight--in 2006,a storm dumped 330,000 tonnes of dust on Beijing in one night. The number of sandstorms has grown alarmingly over the years as the deserts have expanded.This is partly man-made and partly because of climate .Many grasslands have been overgrazed by sheep and goats,or ploughed up,leaving the soil dangerously exposed.Too much water has been taken out of rivers,and the situation is made worse by increasingly long-lasting droughts that have affected the northern half of China as the climate grows warmer and drier.The result is probably the worst loss of rich land to deserts in the world and a dust bowl of extremely large proportions.The nearest sand dunes to Beijing are now only 70 km away and drifting closer each year.At this rate,the desert will reach the city by 2040,and Beijing could become the world's first modern city to disappear under sand.To hold back the deserts,a huge programme of forest planting called the Great Green Wall has been under way for over 30 years.The barrier is planned to be 4,500 km long when completed in several decades ,but the drought is having a very bad effect on the trees and the deserts carry on growing.

 Options: (A) the soil of the grasslands is exposed (B) too much water in rivers has been used (C) it doesn't rain for a long time (D) the climate in northern China is colder and drier

[EX Q]: Article: One day a father and his rich family took his son on a trip to the country with the firm purpose to show him how poor people can be. They spent a day and a night on the farm of a very poor family. When they got back from their trip, the father asked his son, "How was the trip?" "Very good, Dad!" "Did you see how poor people can be?" the father asked. "Yeah!" "And what did you learn?" The son answered, "I saw that we have a dog at home, and they have four. We have a pool that reaches to the middle of the garden; they have a creek that has no end. We have imported lamps in the garden; they have the stars. Our patio reaches to the front yard; they have a whole horizon." When the little boy finished, his father was speechless. The son added, "Thanks, Dad, for showing me how poor we are!" Isn't it true that it all depends on the way you look at things? If you have love, friends, family, health, good humor and a positive attitude towards life, you've got everything! You can't buy any of these things. You may have all the material possessions you can imagine, provision for the future, etc. But if you are poor of spirit, you have nothing! "Command those who are rich in the things of this life not to be proud, but to place their hope, not in such an uncertain thing as riches, but in God, who generously gives us everything for our enjoyment."
