what burn coal and oil to produce energy for industrial and consumer use. 【S1】______
Carbon dioxide and other harmful gases releasing into the air from these 【S2】______
sources adversely effect weather patterns and the health of people, animals and 【S3】______
plants.
Industrialized nations produce most of the world’s air pollution. For 【S4】______

population, the country generates 22 percent of human-made carbon dioxide 【S5】______
emissions or 19 percent of all greenhouse gases such as carbon dioxide and 【S6】______
methane. These emissions harm the environment by leading acid rain and
global warming, and by depleting (使衰竭) the protective ozone layer which 【S7】______
surround the earth.
Acid rain, a serious threat around the world, occurs when sulfur dioxide
and nitrogen oxide emissions from automobiles and fossil-fuel burning power 【S8】______
plants to fall back to Earth as acidic precipitation. Acid rain has contaminated
many lakes in Canada and the northeast United States and has been
documented even in the non-industrial state of Hawaii. In the United 【S9】______

选项
答案
releasing→released
解析
从上下文看,本句的主语是“从这些源头释放出来的二氧化碳和其它有害气体”,release用来修饰前面的名词,且与被修饰的词之间是被动的关系,所以应该用过去分词形式,而不是现在分词。
