Often visible as smog, ozone is formed in the atmosphere from hydrocarbons and nitrogen oxides, two major pollutants emitted by automobiles, react with sunlight. A. ozone is formed in the atmosphere from B. ozone is formed in the atomsphere when C. ozone is formed in the atmosphere, and when D. ozone, formed in the atmosphere when E. ozone, formed in the atmosphere from 答案D,没什么问题.我想问的是书上对E的解释,书上的解释是from后跟完整主谓结构,所以错 那请问对E可不可以这么理解,two major pollutants emitted by automobiles是hydrocarbons and nitrogen oxides的同位语,分词formed in the atmosphere from hydrocarbons and nitrogen oxides修饰ozone. ozone react with sunlight是主句.我觉得E不对是因为意思不对,ozone不和sunlight反应,请问我可以这么理解吗?
