标题: 问个题目,想不明白

Often visible as smog, ozone is forned in the atmosphere from hydrocarbons and nitrogen oxides, two major pollutants emitted by automobiles, react with sunlight.

key: ozoen is formed in the atmosphere when

我的问题是这句话里面的react with sunlight算是什么成分的呢?

react 又是动词,那这样的话一句话里面就有两个动词了啊 ??(is & react)

react with sunlight的主语是hydrocarbons and nitrogen oxides.

is是主句里的动词,而react是从句里的动词。

thx!

看样子我对从句非常的不了解~~~~~~~

从句可以这么用的么?我的理解是two major pollutants emitted by automobiles这是个名字性的结构来补充说明hydrocarbons and nitrogen oxides,可是这样的结构能说是从句么~~~~~还是有点疑惑~~~~~~~~

我得好好补课语法了~~~大脑混乱中~~~~
