Unit 101 The Ozone Hole：Why over Antarctica?
臭氧空洞：为什么出现在南极洲上空?
At its largest this year, the ozone hole covered more than 15 million square kilometers.
今年臭氧空洞最大的时候曾达到1500万平方公里，
Nacreous clouds- also known as polar stratospheric clouds- contribute to the formation of the polar ozone holes.
珍珠云，也称为极地平流云，会造南极臭氧空洞的形成。
For an ozone hole to form, proper weather conditions must also exist.
对一个臭氧空洞的形成来说，必须存在适当的气象条件。
Media reports dubbed the annual thinning a hole in the ozone layer.
媒体报道称之为臭氧层年度稀释“空洞”。
The hole in the ozone layer was discovered over Antarctica almost thirty years ago.
大约30年以前，南极上空的臭氧层上发现有空洞。
The thin area has never become an empty hole, however,
臭氧稀薄区域从未变成一个空洞，无论如何，
There is strong evidence to show that the hole in the Ozone Layer is expanding at an ala123 ing rate .
有确凿的证据显示臭氧层上的空洞正在以惊人的速度扩大。
The ozone hole forms over Antarctica in August and September, when the temperatures are coldest.
南极上空的臭氧洞于8月至9月间天气最冷的时候形成。
The hole in the ozone layer,the greenhouse effect and acid rain are all caused by things we do,and the consequences of our actions are felt all over the world.
臭氧层的空洞、温室效应和酸雨都是我们所为而致。 我们的行为所造成的后果影响着全世界。
