1 . The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?

The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.

Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”

Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”

Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

I respect my English teacher Mr. Li. Not only does Mr. Li has the typical characteristics of a learned man, but he is also a genuine scholar.

One day, I was too exhausted and confused concentrate on that he taught. Unfortunate, I was invited to share with my own idea but I couldn’t say a word. Felt embarrassed, I was ready to be criticized. Much to my astonishing, Mr. Li instructed and encourage me patiently. I was so deeply moved by her attitude.

How a respectable teacher he is!
