The Molai Forest, named after its creator, was once an area    1    (strike) by floods. Teenager Jadav noticed    2     sharp fall in the number of birds and snakes in the nearby forest area and wetland.  

The boy soon turned to his elders and asked, “What if all of us die like these snakes one day?” The grown-ups only laughed. But the boy comforted    3    (he), saying “I will make the planet greener.” 

From then on, Jadav started planting bamboos. He found a small island and planted many young trees. He worked     4    (extreme) hard at this for over three    5    (decade). His work paid off and the land became a    6    (beauty) green forest.  

In 1980, Jadav worked with a team    7     carried out a tree plantation project. And when the project was discontinued after 3 years, he continued    8    (plant) trees.  

Forest is his home now. He regards the recognition and awards he got    9     his wealth. Jadav finds all his    10    (happy) in the forest.

Rainforests, found in Earth’s temperate and tropical(热带的) zones, are some of the most biologically varied ecosystems on the planet. All rainforests share certain     1     features, including a closed canopy—the dense vegetation of the top branches that forms a roof above the forest floor, a damp and warm climate, and    2     constant temperatures throughout the year. Most of the forest’s insect and animal life grows well in the canopy’s leafy and sunlit environment. The forest’s ground cover, by comparison, is small. Less than 2% of the sun’s light makes its way through the canopy and the darkness below. This darkness, along with the poor quality of the soils,     3     plant growth.

Rainforests are a(n)    4     part of Earth’s total ecology. Huge amounts of water are absorbed into tree roots and    5     into the atmosphere from the tree leaves through a process called transpiration(蒸腾作用). Tree roots also fix the soil in place and slow the run-off of rains into rivers and oceans. Through the process of photosynthesis(光合作用), rainforests absorb more carbon dioxide and give off more oxygen than any other ecosystem.

The rainforests are    6     shrinking at a rapid rate as a result of the profitable ventures of farming, logging, and mining. When tropical rainforests are    7     in order to raise cattle and crops, the nutrient-poor soils are quickly exhausted. When farmers move on to new areas, heavy rains and baking sun leave the land fruitless and lifeless. Logging and mining cause similar damage to the land and destroy the territory of    8     millions of birds, insects and animals. By some estimates, an area of tropical rainforest the size of the state of Delaware    9     in this way every month.

3 . Weekly Round-up

①Tours that provide a window on wildlife without harming the animals are a welcome development for Chinese animal lovers, a recent survey found. About 60 percent of interviewees said that they would refuse to take part in tours that might badly influence the normal life of animals in the wild or be harmful to wildlife.

②The number of Chinese studying abroad grew at a slower rate（比率）in 2019, as more students have come to realize that studying abroad does not ensure a well-paid job in foreign countries. About 78 percent of Chinese students abroad plan to work in China either right after graduation or after working abroad for a while.

③A survey by American Councils for International Education，showed that there were 227,086 Chinese learners across the formal US education system, making Chinese the third most popular language being studied.

④Passengers found eating or drinking on the Beijing subway who do not stop when they are asked will face having their actions noted on their social credit（信用）score according to Beijing Municipal Commission of Transport.

Who is willing to drink the polluting water? It can cause us to be ill but even to die. We can’t wait for the moment to protect our water sources. The water we use coming from the ocean, lakes, rivers or streams. But many of these water sources are getting serious polluted. Towns and cities pump sewage（污水）into the water. Many people are throwing all kinds dirty things into the water. Factories poured waste material into the water. Therefore, water sources have become so badly polluted that some of the water is fit to drink or use it. Now it is high time when we should do something to protect our water environment from being polluted.

6 . In the past, man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.

Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to cut down more and more trees. We realize that if rivers are polluted with waste from factories, we will die. However, in most countries waste is still put into the rivers or the seas and there are few laws to stop this. We know, too, that if the population of the countries is rising at the present rate, in a few years, there will not be enough food. What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.

Finally, if we educate people to think about the problems, we shall have a better and cleaner planet in the future.

8 . The climate we live in influences many areas of our lives. The quality of the food we eat，the water we drink，and our homes are all dependent upon our climate and weather. Some scientists have suggested that a warmer world would be a sicker world.

Climate researchers predict that the world climate will become warmer，with high temperatures in summer becoming more frequent and very cold winters more rare.

With winters becoming milder，there are likely to be up to 20,000 fewer cold-related deaths. However，there is a danger that bacteria would no longer die off seasonally during the cold period，which means that diseases may spread more widely.

More heat waves may increase the number of hot-weather related deaths by up to 2,800. Exposure to higher levels of UV light（ultraviolet light）could cause an extra 5，000 deaths a year from skin cancer and may cause an increase of up to 2,000 cases of eye diseases. Warmer summers may cause up to 10,000 extra cases of food poisoning each year.

Higher average global temperatures mean that diseases，or their carriers，may be able to move to areas that were previously too cold for them to survive. It is possible that a mild type of malaria（疟疾）will become established in some parts of the world and be a recurring threat for up to four months each year.

Globally，there are likely to be more floods，more droughts，and more storms，which will cause damage to our homes，food，and water supplies and then influence our health. The same could be said of an increase in flooding which would promote the spread of waterborne diseases，and droughts which would favor white flies and locusts.

Scientists have been studying the relationship between the outbreak of a severe disease in Africa and weather patterns. They believe that a rare climate pattern may come before outbreaks of the disease.

Climate change is likely to have unequal influences on the world population. Those living in poor and developing countries are going to be less able to adapt to the changes. Health influences are not likely to be limited to the human population -wildlife would also be severely affected.
