  一 汽车造成的问题

  1 汽车是主要的空气污染源

  段落大意:汽车尾气是空气的重要污染源,会加剧温室效应,降低空气质量。

  Automobiles are the leading cause to America's air pollution problem. Cars release toxic emissions that damage our environment, hurting our environment by adding to the greenhouse effect, damaging air quality, and decreasing the ozone, not to mention the growing smog problems,disasters done with landfill and the effects done to our water supply, which all are connected with the greenhouse effect, ozone depletion, and air quality.

  2 温室气体的排放增加温室效应

  段落大意:汽车尾气会加剧温室效应,造成气温上升,生物死亡等后果。

  Cars damage our environment by the emissions released from the combustion system of an automobile. Toxic gases weaken the atmosphere allowing for more infrared rays to enter. Having more infrared rays reflected on the Earth warms the Earth, raising the temperature, causing certain vegetation life to die off, the snow caps to melt. Carbon dioxide and carbon monoxide are two greenhouse gases that damage our Earth's atmosphere. Reducing the amount of these greenhouse gases will greatly help controlling these effects.
