科技英语-期末考试翻译-英语句子
Unit1(1)Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level.Ozone can be"good"or "bad"for your health and the environment,depending on its location in the atmosphere.臭氧是一种发生在地球的上层大气和地面之间的一种气体.臭氧对人们的健康和环境是好还是坏的，这取决于它在大气中的位置。
（2）Ozone occurs in two layers of the atmosphere. The layer closest to the EEarth's surface is the troposphere. Here, ground-level or"bad" ozone is an air pollutant that is harmful to breathe and it damages crops,trees and other vegetation. lt is a main ingredient of urban smog. The troposphere generally extends to a level about 6 miles up,where it meets the second layer,the stratosphere. The stratosphere or"good" ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the ssun's harmful ultraviolet(UV)rays.臭氧发生在大气的两层.离地表最近的是对流层.在这里，地面或“坏的”臭氧是一种有害呼吸的空气污染物，它会损害农作物，树林和其他植被.它的主要成分是城市烟雾.烟雾通常延伸到6英里的高空，在那里与第二层平流层相遇.平流层或“良好”臭氧向上延伸6到30英里，保护地球上的生命免受太阳有害紫外线的危害。
