The more I reflect on the 23 impressive years since the
signing of the Montreal Protocol, the more I realize what
far-reaching lessons holds for the global environmental 【S1】______
agreements of today.
As we close the door on the first decade of the 21st
century, the environmental crisis that we face today require 【S2】______
action beyond even the scale of the world’s response to the
ozone-depletion emergency in the late 20th century.
As we all know, the ozone layer is a thin layer in the
atmosphere that sits about 10-50 km above the Earth. It
absorbs most of the harmful ultraviolet radiation to the 【S3】______
sun. The discovery of an ozone "hole" in 1985 shocked the
world and two years ago the Montreal Protocol was signed. 【S4】______
Today, almost every country in the world has ratified the
agreement.
Along with this year’s International Ozone Day, which
was on Sept 16, it is worth recalled that the Montreal 【S5】______
Protocol is not simply a bilateral global accord designed to 【S6】______
eradicate ozone-depleting substances.
In a unique way, the Montreal Protocol brought the
global community altogether to find a way to move forward. 【S7】______
Everyone agreed that what happens to the ozone due to the
release of chlorofluorocarbon gases (CFC) — which used in 【S8】______
aerosols, refrigerators and are still used in air conditioners —
was completely linked to what happens to life on Earth. The
industrial world later provided the incremental financial and 【S9】______
technical assistance to developing countries to implement
out the agreement. 【S10】______
【S8】
选项
答案
∧ were
解析
CFC(氟氯化碳)曾经使用在喷雾剂、冰箱中,目前空调中仍然使用氟氯化碳。后半句are still used是另外一个线索,再次证实前半句应该使用被动语态,即were used。
