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.

Last Friday, our school held a fire drill. Listened to the teacher attentively in the math class, all of a suddenly, we heard a fire alarm from the loudspeaker. The teacher stopped teaching immediately and instructing us to exit the classroom in order. When we got out, heavy smoke had filled with the hallway. We bent down, covered our mouths with wet towels and ran downstairs along the wall into the open airs, just as we had taught before. What moved us were that our monitor made sure everyone was safe after he left the building. Five minutes late, we gathered on the playground. We got to know more about how to protect us properly in case of emergency.
The oceans can absorb 93 per cent of the heat trapped by the greenhouse gases which humans release into the atmosphere. And the other 7 per cent
“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much
However, the ocean itself, as Discover Magazine noted, is heating up 40 per cent faster on average than the United Nations
4 . The early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes, and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.
The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.
As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.
Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.

5 . Who would have thought that there was any connection between a cup of coffee and a bird, butterfly, or even a bat? Such seems to be the case, however, as methods for growing coffee plants have gradually changed over time.
Coffee plants were first discovered growing in Africa hundreds of years ago. The plants grew under a wide cover of forests, which protected the coffee plants’ leaves from the burning sun. As coffee was introduced to other countries, farmers would naturally try to grow the plants in the shade of tall trees. These trees provided more than shade for coffee plants; they were also home for many species of birds, insects, and other plants.
Over the past 30 to 40 years, people developed a new kind of coffee plant, one which grows well in open sunlight. Sun-grown coffee produced two times more coffee than shade-grown coffee in the same amount of time and space. As a result, the growing need for coffee makes the sun-grown method appear to be the best way to grow coffee.
However, this newer method has some unexpected results. First, the lack of tree cover leaves the land open to heavy rainfall, which can wash away the soil’s nutrients (营养物质). This necessitates an increased use of fertilizers and additives, which is likely to create health risks. Second, as forests are taken down to make way for sun-grown coffee plants, native and migratory birds no longer have a home. This is threatening many species, and the effect is now being examined and recorded by ornithologists, who are discovering sharp falls in some species that travel to the northern United States each year. Finally, more pesticides (农药) are used in the sun-grown method, all of which have a bad influence on both the environment and the long-term health of the coffee plants themselves.
Today, as more people recognize the problems of coffee grown in the sun, perhaps they will be willing to pay the higher prices, encouraging coffee growers to return to the more natural method of producing this worldwide product.
