From VOA Learning English, this is the Agriculture Report. Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water used on coastal farms. As a result farmers are increasingly unable to use fields close to the sea. Scientists call this process "salinization." The term comes from the word "saline" -- which means a mixture of salt and water. ___________________________ 美国之音慢速英语农业报道 气候变化引起了海平面上涨.这就增加了沿海农场淡水中盐分的含量.最终会导致农民无法再使用靠近海域的土地. 科学家们称这个过程叫"盐碱化".这个术语源自于"生理盐水"这个单词,这就表示其中混合盐和水._________________________
