CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTION
We   1   (know) about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with   2   (melt) ice and rising sea levels provide evidence of a dramatic change in the global climate.
In 2013, a lot of people were   3   (shock) by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists   4   found its dead body, all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have   5   (starve) and died. Experts claimed that low sea-ice levels   6   (cause) by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s   7   (ecological).
Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process   8   (call) the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to the fact   9   heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat   10   (release) back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge   11   (amount) of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly.
There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that   12   we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are   13   (frequent) broadcast about extreme rainstorms and heatwaves causing deaths and economic losses.
14   (continue) greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility   15   (seize) every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help?

REDUCING WATER POLLUTION IN THE LI RIVER
The beautiful Li River and its amazing surrounding scenery is one of the most well-known tourist
1   (destination) in China’s Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects   2   the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.
3   (previous), water quality in the Li River had suffered greatly from an increasing volume of tourists, many of whom frequently threw garbage into the river. Many tour boats contributed   4  
the problem too. Kitchens on board were using lots of oil,   5   was often thrown into the water. The growth in tourism also meant the local population rose rapidly, as well as   6   number of commercial and industrial enterprises. Water pollution levels increased, with more household and commercial waste   7   (end) up in the river. In order to feed more people, more chemicals were used to increase crop production. These chemicals led to severe water quality issues, causing a decrease in the number of fish species. Local officials were   8   (concern) that the pollution was damaging the natural environment and felt that urgent steps should be taken   9   (restore) the river’s original beauty.
A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water   10  
(conserve). The collection and transport of household waste was also improved.   11   (dozen) of polluting enterprises were closed or moved. The local government set up strict regulations regarding   12   (far) industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental   13   (aware) and encourage greater use of clean energy. At the same time, they started to carry out   14   (inspection) regularly and fine tourist organisations for abuses. With these measures, it is   15   (believe) that the beauty of the Li River will be preserved for generations to come.
In addition, the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives, such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, China’s waterways are heading towards a clean and sustainable future.
