On Monday, millions of people in Ethiopia planted more than 350 million trees in 12 hours. The    1    (origin) goal had been to plant 200 million trees that day. The event was part of    2    country’s Green Legacy Initiative (绿色遗产计划). It is designed    3    (decrease) the effects of deforestation (滥伐) and climate change in the East African country.

According to the United Nations, Ethiopia’s forest coverage was 35% in the early 20th century but it is just above 4% now. The Green Legacy Initiative’s goal is to plant 4 billion trees in Ethiopia this year. So far, about 2.6 billion    4    (plant). Other countries and groups have taken similar efforts. In 2017, volunteers in India planted 66 million trees in 12 hours. Australia plans to plant a billion trees    5    2030. The African Union, a group of 55 African countries,    6    (be) building a “Great Green Wall” of trees to stop the spread of the Sahara desert.

    7    (recent), Swiss scientists released a new report in the journal Science,    8    (say) that planting 1.2 trillion trees around the world could help absorb carbon emissions,    9    pollute the air. Trees use carbon dioxide to grow and store the carbon in their    10    (leaf). This removes it from the air.

There     1     (be) no lights in sight but the night sky glowed (发出) a dusky yellow, because the Amazon was burning. The yellow flames engulfed (吞噬) trees     2     lit up the sky. During the day, the sunshine was blocked     3     thick smoke. So far, the fire     4     (put) out.

The government has recorded 72, 843 fires. The fire is just one of     5     (they) in the Amazon, the world’s     6     (large) rainforest and a fighter against climate change. According to Brazil’s space research agency INPE, the wildfire has decreased by 17 percent so far this year compared to the same period in 2018.

Environmental     7     (group)said the policies of the government encouraged deforestation (采伐森林) of the Amazon,    8     led to more fires. But the government posted a report and wanted     9     (argue) against that. The government claimed that non-governmental organizations     10     (angry) set fire to the forest after it cut their funding.

4 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).
