你想想啊,首先,煤电厂排放的不只是二氧化碳,还有其它有害气体,比如氧化氮和二氧化硫,这些有害气体的排放量比汽油汽车高很多。其次,在制造电动汽车时,它对环境的破坏更大。先要生产锂电池吧,这些锂电池体积很大,制造费用昂贵,尤其是特斯拉的电池更贵,它比对手的电池要更大更强大。许多电动汽车的电池要用到稀土,它本来就稀缺,而且提炼也耗钱。特斯拉的AC感应电动机没有使用稀土材料,但是公司的工程师也承认,S型汽车生产时消耗的能源比凯美瑞多。因此,在最初上路之前,S型汽车就已经远比其它汽车污染重了。你开得越久,它才越绿色。

Think about it. First, coal-fired power plants do not only emit carbon dioxide, but also other harmful gases; for example, nitrogen oxide and sulfur dioxide. The amount of emissions from these harmful gases is much higher than what comes from gasoline cars. Secondly, the damage to the environment is greater when manufacturing electric cars. First you need to produce a lithium battery. The volume of these lithium batteries is huge, so it is costly to manufacture them. Tesla's batteries are even more expensive as they are bigger and stronger than the competitor's. Many electric car batteries use rare earth elements, that are scarce, and which are costly to extract. Tesla's AC induction motor doesn't use rare earth materials, but the company's engineer also admits that when producing Model S cars, the consumption of energy is more than for a Camry. Therefore, in the beginning, before you get on the road, Model S cars have already caused much more severe pollution that other cars. The longer you drive it, the greener it will then become.
能使燃着的木条越烧越旺的是氧气,被点燃的是氢气和一氧化碳。然后再用澄清的石灰水检验燃烧生成的气体。因为一氧化碳燃烧会生成二氧化碳。

The one that can make the wooden splint burn brighter and brighter is oxygen. The ones that ignited were hydrogen and carbon monoxide. Afterward, use the settled limewater again to test the gas produced by the burning. Because carbon monoxide produces carbon dioxide when burned.
