阅读简答题专项训练·附详解(04)

 

The Sahel is the area of Africa that lies between the Sahara desert to the north and more fertile land to the south. The dry plains of the Sahel are mostly treeless. Yet in Niger, one of the once also poor nations along the Sahel, millions of trees are now growing.

Researchers have been studying the progress of a re-greening campaign in Niger. Chris Reij is a scientist from the Netherlands. In a message at frameweb.org last February, he described how, in some places, "densities are so high that you almost look at a wall of trees."

A United Nations news service reported in October that Niger's government said the campaign had already reclaimed three million hectares (公顷). Teams of workers have used simple methods such as planting trees and protecting natural vegetation to save land from being lost to desert.

Ten to twenty times more trees were reported in parts of southern Niger in 2005 than there were thirty years earlier.

Some reclaimed land can now be farmed again. The land became infertile during the 1970’s and early 80’s. But about twenty years ago, local farmers recognized that their once-productive soil was being carried away by severe winds.

Trees were traditionally cut down for firewood or cleared for agriculture. Instead of clearing trees, farmers began to let them grow among their crops. At the same time, rainfall levels began to rise after a long dry period. Today, the rate of desert expansion in Niger is dropping and the amount of harvested crops is up.

The success of the effort suggests that earlier damage to the Sahel may not have been permanent. and some say it could put Niger in a better position to deal with whatever effects climate change might bring.

73. Find in the passage a word closest in meaning to the underlined word “reclaim”.

74. What was the situation of Niger’s land before the 1950’s? (回答词数不超过6)

75. according to the passage, what lesson can we learn from it? (回答词数不超过8)
