The first Earth Day took place on April 22，1970.Twenty million Americans，about 10% of the US's population then，demonstrated（示威） against the widespread attitude at the time of ignoring environmental issues.Now，50 years later，Earth Day remains an important event to draw attention to necessary actions to protect the planet.Unfortunately，threats to the environment also continue，including at least one that certainly wasn't as apparent in 1970.
The first Earth Day，notes EDN （Earth Day Network，the global organizer of Earth Day），caused a wave of action，including the passage of landmark environmental laws in the United States such as the Clean Air，Clean Water and Endangered Species Acts，as well as the creation of the Environmental Protection Agency （EPA）.Many countries soon adopted similar laws，it adds.
Today，EDN works with more than 75，000 partners in over 190 countries.The theme of 2020 Earth Day is climate action.Thanks to groups like EDN，public awareness and demands for better environmental management have grown dramatically and prompted great progress is many areas.
One problem that hadn't surfaced much in 1970- the harm of unwanted plastics -has become a major environmental issue.It is drawing increasing attention and is stimulating efforts both to find productive uses for the waste materials and to develop more environmentally friendly alternatives.
Among the recent coronavirus global pandemic （流行?。?，EDN marked the 50th anniversary of Earth Day with the first Digital Earth Day，a global digital mobilization （動員） on April 22 to address the most urgent threats to people and the planet.
"At Earth Day Network，health and safety of volunteers and participants in Earth Day events are our top concern.Among the recent outbreak，we encourage people to rise up but to do so safely and responsibly-in many cases，that means using our voices to drive action online rather than in person，" said Kathleen Rogers，President of Earth Day Network.

1．Imagine mountains enveloped in silver water，shining in the spring sun.Summer sees the mountains turn bright green with growing rice.During autumn，these mountains are gold，and in winter they are covered with white frost.（1）
These terraces（梯田） were built by the local Zhuang and Yao people.Starting in the Yuan Dynasty，work on the terraces took hundreds of years.（2）Reaching as far as the eye can see，these terraces cover tall mountains，often from the bottom to the very top.
（3）Firstly，there are few large flat areas of land in the region.Building the terraces could increase the areas to grow rice.Secondly，although the region has plenty of rain，the mountains are steep（陡峭） and the soil is shallow，The fat terraces help catch the rainwater and prevent the soil from being washed away.
But perhaps the most important is the way people have worked in peace with nature.The terraces are cleverly designed，with hundreds of waterways connecting with each other.During the rainy season.rainwater moves down the mountains and into the terraces along these waterways.The sun heats the water and turns it into vapour（水蒸氣）.（4）These terraces also provide a perfect environment for birds and fish，some of which feed on insects harmful to crops.
Although modern technology helps produce more crops，these terraces still mean a lot to the local people for whom traditions hold much value.（5）Thus，new generations continue to use ancient methods of agriculture to maintain the terraces.Today，the Longji Rice Terraces attract thousands of visitors to admire this great wonder created by people and nature working together.
A.Terraces were built to collect the rain.
B.These are the colors of the Longji Terraces.
C.This knowledge is passed down through families.
D.It wasn't completed until the early Qing Dynasty.
E.So how did people change the entire mountains into terraces？
F.This forms clouds from which rain falls down onto the terraces again.
G.So why did these people take trouble turning the entire mountains into terraces？發布：2025/1/1 17:30:2組卷：3難度：0.5 -
