Feeling hot? So is the earth. Because of problems like climate change and bad ways of farming, much of the planet's land is drying up. What can we do to solve this problem?
One thing the United Nations did was to create a holiday. In 1994, the UN started World Day to Combat Desertification and Drought(世界防治荒漠化和干旱日), to let more people know about desertification. It is on June 17 every year.
Desertification happens when healthy land—land full of water and nutrients(营养物)—becomes desert, which is dry and unhealthy. Every year, 20,000 to 50,000 square kilometres of the earth's land is lost to desertification. In Africa, scientists predict that two thirds of Africa's healthy land will be lost in the future.
Desertification sometimes happens because of climate change since big and fast changes in temperature can kill plants and trees.
However, it also happens because people use land too much, and in bad ways, to grow food on their farms. Growing too many plants in the same soil, in too short a time, can take away the soil's nutrients faster than the soil can make new ones. That can turn the soil into dry sand, like a desert.
The UN suggests some different actions to stop desertification. One is to teach people better ways of farming, including the use of better fertilizers(肥料). Another is reforestation, which means planting more trees. One country that has done a lot of that is China. China has about 4,000,000 hectares(公顷) of reforested land per year—more than anywhere else in the world.

感觉热吗？地球也是如此。由于气候变化和不合理的耕作方式等问题，地球上的大片土地正在干涸。我们能做些什么来解决这个问题呢？
联合国采取的一项措施是设立一个节日。1994年，联合国设立了世界防治荒漠化和干旱日，以让更多的人了解荒漠化问题。这个节日在每年的6月17日。
当肥沃的土地——充满水分和营养物质的土地——变成沙漠时，就会发生荒漠化，沙漠是干燥且贫瘠的。每年，地球上有2万到5万平方公里的土地因荒漠化而消失。在非洲，科学家预测未来非洲三分之二的肥沃土地将会消失。
有时，气候变化会导致荒漠化，因为气温的剧烈且快速的变化会杀死植物和树木。
然而，人们过度且不合理地使用土地来耕种农作物也会导致荒漠化。在同一块土壤中短时间内种植过多的植物，会比土壤生成新营养物质的速度更快地耗尽土壤中的营养物质。这会使土壤变成干燥的沙子，就像沙漠一样。
联合国提出了一些不同的行动来阻止荒漠化。其中之一是向人们传授更好的耕作方法，包括使用更好的肥料。另一个是重新造林，也就是种植更多的树木。中国在这方面做了很多工作。中国每年约有400万公顷的土地被重新造林——比世界上任何其他地方都多。
（C）1. 如果发生荒漠化，土地会是什么样子？
A. 它充满了水。
B. 它有更多的营养物质。
C. 它干燥且贫瘠。
D. 它适合居住。
（B）2. 为什么在同一块土壤中种植过多的植物不好？
A. 因为它会快速改变气候。
B. 因为它会快速耗尽土壤中的营养物质。
C. 因为它会赶走当地的动物。
D. 因为它会取代森林。
（D）3. 以下哪一项不会导致荒漠化？
A. 气候变化。
B. 过度使用土地。
C. 使用劣质肥料。
D. 重新造林。
（C）4. 最后一段主要讲了什么？
A. 荒漠化的原因。
B. 联合国改善农业的计划。
C. 联合国防治荒漠化的建议。
D. 重新造林的重要性。
