绿化 afforestation
全国绿化委员会办公室3月11日发布《2019年中国国土绿化状况公报》。
China has made new strides in advancing afforestation in 2019 with the area of newly created forests totaling 7.067 million hectares, the report said.公报指出，2019年我国国土绿化事业取得了新成绩，全国共完成造林706.7万公顷。
【单词讲解】
这里的afforestation读作[frsten]，是个名词，其英文解释为the process of planting large numbers of trees on land which has few or no trees on it，即“在原本树木稀少或者没有树木的土地上大量种树的过程”，也就是我们所说的“植树造林”，由此可见，这是一个人为绿化的过程。植树造林产生的森林一般称为“人工林（manmade forest）”，与之相对的“天然林”就是natural forest。
