Wuyi Mountain, as a national nature conservation area, is well-known for its clear water and beautiful peaks. There is little doubt    1    it attracts millions of tourists from home and abroad annually.

But I’m concerned that the increasing number of tourists has had a negative impact    2    the environment. Garbage    3    (throw) around. Enterprises producing tourism-related products burn fossil fuels,    4    (cause) smog in the air. Restaurants release oily water into the river, making it dirty and smelly. “What should I do to help restore the    5    (harmony) ecological system here?” That is what I have been thinking about. Therefore, on behalf of the students of our school, I put forward the following suggestions.

To begin with, the government is supposed to adopt     6    (policy) to restrict the volume of tourists. Next it can carry out inspections into enterprises    7    (regular) and fine those who fail to solve pollution problem properly.

In addition, it is also the government’s responsibility    8    (seize) every opportunity to educate people to reduce their carbon footprints. It’s believed that if the government takes appropriate actions and    9    (put) environmental reforms in effect, we won’t have to be trapped in this environmental chaos. Only then can Wuyi Mountain head towards    10     sustainable future.

Several strange things happened before the Earthquake hit Tangshan. Some     1    (smell)gas came out of them and chickens were too nervous to eat. And in less than one minute, the whole city lay in     2    (ruin). The country united as one to relieve the disaster, and soldiers were sent to dig out those who     3    (trap) under the damaged buildings.

Planting trees is a great way to reduce carbon emissions, but protecting our oceans and coastal ecosystems can do the same?

“Blue carbon” refers to organic carbon which     1     (store) by the oceans and coastal ecosystems. Mangroves, tidal marshes and seagrasses are the three main coastal ecosystems that can store large     2     (quantity) of blue carbon. They play a major role in reducing carbon dioxide in the air.

    3     (compare) with ecosystems on the land, coastal ecosystems can store carbon     4     (constant) in the long term. When plants on the coast die, the organic deposits that they become will slowly disappear thanks to the flowing seawater above,     5     means the carbon will not escape easily but remain stored for hundreds and thousands of years.

China is one of the few blessed     6     all three coastal ecosystems. Tidal marshes are the largest coastal ecosystem in China,     7     (occupy) an area of 5,448 square kilometers. In comparison, mangroves have a     8     (small) size. According to the latest data, the total area of China’s mangrove forests in 2020     9     (be) 289 square kilometers, and over 70 square kilometers of mangroves are newly planted and restored now.

By protecting and restoring these coastal ecosystems, we can avoid enormous amounts of stored blue carbon going back into     10     atmosphere, and safeguard wildlife living in these ecosystems.

Water shortage is one of the     1     (great) crises facing us today, with two thirds of the global population living in areas     2     water is scarce(稀缺的) for a month or more every year. There are two contributing factors to this problem: increasing global demand     3     water, and unsustainable means by which these demands are being met. Yet, despite global water usage already increasing threefold(三倍) over the last fifty years, it     4    (predict) that there will be a further 60%-100% increase in water usage by 2050.

This is not just     5     matter of turning the tap off when you brush your     6     (tooth), cutting your showers down to 3 minutes, or sharing the washing-load with your flatmates. In fact, daily activities of human make up less than 4% of our total water consumption, with the     7     (remain) 92% falling into two ‘invisible’ categories: the industrial production of household items, and the production of food. Astonishingly, 69% of our total daily water consumption comes from the     8     (grow) and production of food alone.

    9     (unfortunate), there is no single go-to refererence book for the exact number of litres used in the production of any individual food item. This is a hard pill to swallow, for we have other factors     10     (consider) when weighing up the benefits of every food choice: taste, cost and convenience.

World Wetlands Day, celebrated annually on February 2^nd, aims to raise global awareness about the important role of wetlands for people and our planet.

World Wetlands Day     1     (adopt) by the United Nations in 2021. It makes efforts     2     (realize) the long Sustainable Development Goals (SDGs) and deal with global issues related to climate and biodiversity (生物多样性) challenges. Now with seven years left for the SDGs, the UN is calling again to restore wetlands.

This year’s theme is “Time for Wetland Restoration,”     3     brings to attention the rapid loss of wetland systems worldwide. In just 50 years, 35% of the world’s wetlands     4     (lose) since 1970. Wetlands are disappearing three times     5     (fast) than forests and are Earth’s most     6     (threaten) ecosystem. Human activities that lead to loss of wetlands include construction, pollution, overfishing and so on. It is     7     opportunity for us to rethink and change how humans impact the environment.

While wetlands cover just 6% of the earth’s surface, they are home     8     about 40% of the world’s plant and animal species. Wetlands provide people with food and water, offering natural protection and     9     (serve) many other important functions.

Huge changes are needed to solve the climate and biodiversity crisis, yet there are small things we can all do to keep our wetlands and our wildlife     10     (health).

Scientists have rediscovered a species of frog last seen more than 80 years ago. They relocated the small Hall’s water frog named after the American researcher Frank Gregory Hall     1     discovered the species in 1935 in a tiny hot spring near Ollagüe in Chile’s Atacama desert.     2     discovery made the scientists try their best to confirm(证实)that the so-called ghost species was indeed the same one Hall had discovered decades ago. “We asked the museum where Hall’s discovery was registered. They sent us a large number of     3     (picture),” said César Cuevas, a researcher from the Catholic University of Temuco.

The journal Zootaxa     4     (publish) the tale of the rediscovery last month. “Researchers made an effort     5     (establish) the frog’s ties to other species found in the region in order to determine how different, and therefore, how rare, it     6     (real) is. Meanwhile, protecting its habitat     7     (be) key,” Cuevas said. Mining, tourism development and expanding cities in Chile’s north, home to the world’s     8     (large) copper(铜)industry, all compete for water     9     the rare(罕见的)animals. “These animals are always living in the water. In just five minutes out of the water, they die,” Cuevas said in a call to protect     10     (they) habitat before it is too late.
