1 . 阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。

This year marks the 50th anniversary of Earth Day. A half-century ago, activists       1    (walk) to the street to speak out for the protection of the planet in       2    (respond) to one of the worst oil spills (原油泄漏) in history. These activists inspired important changes in how our society views the environment,     3    (lead) to the creation of the Environmental Protection Agency. But protecting the earth is also a social justice issue. People of color and poor people are often the first       4     (suffer) from the climate change, because they live near highways, factories, or garbage dumps,       5     there are more pollutants, for example, and they may not be able to afford fresh green foods.

But you don’t have to be an activist to make       6    difference—in fact there are many tiny everyday       7    (effort) you can make to help the planet. The environmental movement didn’t start with Earth Day and indigenous people (原住民) protecting the earth as     8    (they) way of life were the pioneers. I wish that everyone would see the   climate crisis this way and take it       9     (serious) as well. It isn’t just polar bears and plastic bags     10    an issue that will determine the future of life. So, actually, every day is Earth Day.

2 . If the three Rs (reduce, reuse and recycle) is a guideline to save the planet, garbage-sorting is where the   efforts start. Since May 1, Beijing has started to carry out mandatory garbage-sorting in new efforts to better protect the environment. Under the new regulation, residents are required to classify household waste into four categories: kitchen, recyclable, hazardous and other waste. People who fail to sort their garbage properly can be fined from 50 to 200 yuan, reported Xinhua.

Some residential communities in Beijing have introduced rewards to encourage residents to sort their garbage. According to Xinhua, residents can earn points by classifying their domestic waste correctly and then exchange the points they accumulate for daily necessities such as soap.

Garbage sorting practices have reached over 70 percent of housing estates in 18 cities, including Shanghai,     Xiamen and Hangzhou, according to the Ministry of Housing and Urban-Rural Development. Shanghai first enacted a mandatory garbage-sorting regulation in July 2019 and has had a 90 percent compliance (服从) rate among its housing estates.

According to a report by the Ministry of Ecology and Environment, over 90 percent of the public believe that garbage-sorting is important for the protection of the environment. However, garbage-sorting is still a big problem in China. Only 30 percent of participants said they think they are completely sorting their waste, the report noted. According to Xinhua, it’s partly because many people lack the willingness to sort their own waste. Also, some previous garbage regulations didn’t include fines for people who failed to obey them.

“It’s a must to have a legal guarantee to promote garbage sorting,” Liu Jianguo, a professor from Tsinghua University, told China Daily, “Aside from China, many countries like Germany, Spain and Britain, also ask people to sort waste into specific categories. In Japan, there is a fixed time for the sorting of each kind of garbage and littering.”

3 . Kevin Randall, a teacher,who teaches biology at Grandville High School,runs the environmental club at the high school,which has around 2,000 students.The club is known as the GHS Green Team,and it aims to raise awareness among students and teachers about sustainability(持续性).It also works on projects to reduce the environmental footprint of the building itself.

One of the club's recent projects focused on reducing waste in the school cafeteria.Randall said their cafeteria supervisor told them that the school went through 54,000 plastic forks every year.The club applied for a financial help,built recycling centers for the cafeteria,and purchased metal silverware.

And now every student uses a durable metal fork or a spoon instead of disposables.(一次性用品),“and that's just one way we're trying to capture the low-hanging fruit,if you will,"Randall said.

The efforts of Randall and his students have earned Grandville High School the Michigan Green School certification from the state.In addition to their work reducing waste in the cafeteria, the GHS Green Team has also built a garden with flowers and vegetables on campus,and leads cleanups on site and out in the community.Over the years,Randall and his students have also been working on raising money to install solar panels(太阳能板) on the roof of the high school.

Randall said he was motivated to take the lead on environmental issues for his school because he wanted his students to have someone to turn to in the building who understands what's at stake(利害攸关）when it comes to climate change.

＂And I also felt like I needed to do more in my life for my own two children at home," Randall added,"They need to know that their dad is working as hard as he can to reduce the effects of climate change,and to spread the word,and to make sure that other students out there are learning about this just the way they are at home."

4 . The Great Wall, China

Stretching over 21,000 kilometers, the Great Wall was built to prevent invasions and has a history of more than 2,000 years. UNESCO in February 2019 calls it an absolute masterpiece, not only because of the ambitious character of the undertaking but also the perfection of its construction.”

But perfection isn’t protection. 51.2 percent of the Great Wall had either already disappeared or is at a significant risk of disappearing. Besides for wind and rain erosion, the main reasons for the destruction of the Great Wall are human factors such as tourism, construction, human contact and so on.

Pamukkale，Turkey

Pamukkale, which means “cotton castle” in Turkish, is famous for its shining white calcite terraces (方解石阶地)with warm and mineral-rich waters overrun.

Before being listed as a World Heritage Site in 1988, Pamukkale had been severely damaged by human activities. People used hot spring water to fill swimming pools, some visitors stood on the rocks and some even bathed in the hot springs with soap and shampoo. To protect the terraces, the Turkish government has decided to pull down the hotels and require all tourists to visit this site barefoot.

Great Barrier Reef, Australia

Home to 400 types of coral and 1,500 species of fish, the Great Barrier Reef draws visitors to Australia from all over the world.

However, the Great Barrier Reef is expected to suffer from increasingly frequent bleaching events, cases in which corals turn white and may die, according to a UNESCO report. The heat waves caused by global warming have killed half of the coral here in the two years, according to a CNN report. Pollution from industry developments and harmful fishing practices are also big concerns.

The Dead Sea, Jordan

At 423 meters below sea level, the Dead Sea is 10 times saltier than the ocean, meaning that the water is so dense, even tourists who can9t swim will be able to float.

But the seaside resorts built in the 1980s now sit kilometers away from the water’s edge, which has lost half of its surface area in the past 40 years. The damage is irreversible due to the nature of the mineral industry and the type of agricultural use that has drained the water.
