High on the Qinghai-Tibet Plateau     1    (lie) China’s “water tower” Sanjiangyuan. It is home to the headwaters of China’s three rivers: the Yellow River, Yangtze River, and Lancang(Mekong) River. It is the three rivers     2     provide water for about half the population of China. However, human activities are putting this ecosystem     3     risk. Hopefully, though, we can repair this damage. In 2016, the Chinese government established Sanjiangyuan National Park in Qinghai province. The park,     4    (schedule) to open in 2020, has increased the area’s green coverage and attracted more wildlife. The local government has also made great effort to improve biological diversity. The success of Sanjiangyuan will mark the start of a     5    (green) future. With Sanjangyuan     6    (take) the lead, nine other regions in China     7    (choose) by a field conservation station to carry out projects over the past three years,     8     will form a national park system together. The idea of a national park system is still new in China, but    9    (it) realization is urgent. After all, building an ecological civilization bears great       10    (important) in the development and progress of human civilization.

Environmental problems are significant in many people’s minds, but it’s     1     younger generation who is particularly concerned about the future of our planet. From global school strikes for climate change action     2     amazing teen activists, kids are now taking it into their own hands.    3     (promote) this love for the earth, a new bill that requires students to plant 10 trees each before graduation     4     (pass) in the Philippines on May 15, 2019. In the past years, the Philippines     5     (lose) more than 30% of its forest cover. But 175 million trees could be planted by students each year under the     6     (fantasy) program, which means the students in the Philippines can help improve the situation. The action of planting 10 trees is an     7     (extreme) easy task for the average student: a kid graduating from elementary school, a teen graduating from middle school, a young adult graduating from college — but their small actions will add up quickly to work wonders.

In fact, this isn’t the only positive program     8     (involve) the younger generation. Some schools in India made students pay their “school fees” by collecting, bringing to school and recycling any plastic waste     9     was lying across the town. This type of activity has helped raise     10     (aware) of plastic waste in Asian countries.
