2 . A tree planting initiative in Kenya has seen over 30,000 trees being planted. The Green Generation Initiative is a Kenyan charity that has been planting trees to counter climate change and the reduction in forest in the East African nation since 2016.

Founded by climate activist Elizabeth Wathuti, the initiative's primary focus is on developing young climate activists through environmental education in schools and addressing food insecurity in the region through planting fruit trees. Since its foundation, over 30,000 trees have been planted in Kenya, while thousands of school children have not just planted trees but adopted them to ensure that young people learn the importance of acting as a guardian of the health of the environment. The trees have recorded a survival rate of over 98 percent, as they continue growing from young trees to maturity.

Speaking to world leaders at the recent UN Climate Change Conference in Glasgow (COP26)，Elizabeth issued a serious warning about the threat of climate change: “Over two million of Kenyans are facing climate­related starvation. In 2025, half of the world's population will be facing water shortage. By the time I'm 50, the climate crisis will displace over 80 million people in sub­Saharan Africa alone.”

Elizabeth said, “I have been doing what I can.Inspired by the great Wangari Maathai, I founded a tree growing initiative that enhances food security for young Kenyans. So far, we have grown 30，000 fruit trees, providing desperately needed nutrition for thousands of children.” “Every day we see that when we look after the trees, they look after us. We are the adults on this Earth right now, and it is our responsibility to ensure that the children have food and water, ”she added.

China will     1    a new batch of national parks this year on the Qinghai-Tibet Plateau, and in the basins of the Yangtze River and the Yellow River, said the National Forestry and Grassland Administration on Sunday.

Through years of efforts, China has effectively protected 90 percent of       2     terrestrial ecosystem types, and increased the wild populations of over 300 rare and endangered wild animals and plants, according to the administration. China will     3    the development of a     4     system based around national parks, it said, adding that more than 80 percent of key state-protected wildlife species and their habitats will be     5    .

There is little doubt that Earth is getting warmer and warmer. In 2013, a lot of people     1     (shock) by a news photo of a dead polar bear     2     appeared to have starved and died. This alarming case showed how the increase in temperature had     3     effect on Earth’s ecology.

Climate scientists often mention a key climate process     4     (call) the “greenhouse effect”, which has two common meanings. Without the “natural” greenhouse effect, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem because more heat energy is trapped in the atmosphere, causing Earth’s surface temperature to rise     5     (quick).

There is strong evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only     6     (cause) serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a     7     (high) price to pay.

Governments need to consider making     8     (policy) and taking appropriate actions to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint”. It is our responsibility     9     (seize) every opportunity to educate everyone about global warming, along     10     its causes and impacts.

The Li River is one of the     1     (destination) tourists won’t miss. However, with the number of tourists increasing, the river’s water was polluted. Some tourists     2     (frequent) threw garbage into the river. Kitchens on the tour boats were using lots of oil,     3     was often thrown into the water. Besides, more chemicals were used to increase crop production,     4     (cause) water quality issues and a decrease in the number of fish species. These problems made the local officials worried about the natural environment. They felt urgent steps should be taken     5     (restore) the river to its original beauty.

The waste water treatment facilities were constructed, which helped improve the water quality and water     6     (conserve). Dozens of polluting enterprises     7     (close) or moved. What’s more, the local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. With these measures,     8     is believed that the beauty of the Li River will come back soon.

What is     9     most amazing is that the “Water Ten Plan” is now tackling water pollution across the country. With such campaigns     10     effect, China’s waterways are heading towards a clean and sustainable future.

That’s all. Thanks for your listening.
