例题6：
DESERT FORMATION
Paragraph 9: The final major human cause of desertification is soil salinization resulting from over irrigation. Excess water from irrigation sinks down into the water table. If no drainage system exists, the water table rises, bringing dissolved salts to the surface. The water evaporates and the salts are left behind, creating a white crustal layer that prevents air and water from reaching the underlying soil.
All of the following are mentioned in the passage as contributing to desertification EXCEPT
1.Soil erosion
2.Global warming
3.Insufficient irrigation
4.The raising of livestock
