In the early years of the Qing Dynasty. Nanhu Lake was a scenic wonderland in Yunnan Province.

In order to get an    1    (office) rank, a scholar named Yang studied hard on an island in the middle of the lake. with one stone bridge linked the bank. His wife sent    2    (meal) to him every day. She usually made chicken soup with some rice noodle, meat and vegetables. Because of the great distance. when she get there, the food    3    (become) cold and unappetizing.

One day, she cooked the food in a heated earthen pot. And she was so surprised    4    (find) that the food was will hot when she got to the island. After    5    careful study, she found two secrets; there was thick chicken oil on the surface of the soup and the earthen pot did not    6    (ready) conduct heat. As a result, the heat of the soup    7    (preserve) well.

Since then, the scholar became    8    (healthy) and more hardworking. Finally he succeeded in a government ?. He treated his fellow scholars    9    the nice noodles with chicken soup. They praised it repeatedly and asked    10    the splendid meal was. Thinking of he stone bridge she crossed every day, the wife blurted out (脱口而出) "crossing-over bridge rice noodles".

China is the home of tea. Since ancient times, tea     1     (become) part of Chinese culture,     2     (leave) its smell in poems and customs. Many tea lovers enjoy tea not only for its taste, but also for the beauty of tea ceremonies (仪式).

Traditionally, picking tea leaves is an     3     (importance) activity in spring in South China. The earliest batch (批) of tea is often ready to be picked before Qingming, in early April     4     the temperature begins to rise and rain increases. This kind of tea, which is called Mingqian tea, is     5     (high) praised for its good quality.

East China’s Zhejiang province is considered as     6     major producer of tea. White Tea in Huzhou city’s Anji county and West Lake Longjing Tea in Hangzhou are famous in both China and abroad.     7     spring, local hills of those places are filled with tea workers who work on their land. In the busy seasons,     8     (tourist) from different areas of the country travel there to see the sights of tea farms and enjoy a freshly     9     (prepare) cup of tea.

Thousands of years ago, by the hands of the Chinese people, a leaf     10     (make) into a delicious drink. It has traveled a long way and continues to play a role in Chinese culture.

【推荐1】There is no doubt that the world climate     1     (change) in recent years. Many people blame this change on gases such as carbon dioxide. Animals and humans produce carbon dioxide when they breathe. However, many other human     2     (activity) also let off carbon gases. Anytime something is burnt, carbon is put     3     the atmosphere. Cars and other vehicles burn petrol in their engines, and electrical power plants most often burn fuels such as coal and oil in order to produce electricity.    4    , the more petrol and electricity we consume, the     5     carbon we are letting off.

One thing we can do to help solve this problem is to walk or use     6     bicycle when possible. Of course, there are times     7     we need to travel long distances. In this case, public transport such as buses and the underground is always a much better choice than a private car or a taxi.

You can also plant a tree,    8     trees absorb the carbon dioxide in the air to produce oxygen. Planting a small tree is cheap and easy, and two decades from now, when you look at     9     will have become a large tree, you will find a sense of satisfaction,    10     (know) that you did your part to help solve the problem of climate change.

In recent years, we have seen melting ice caps and     1     (rise) sea levels around the world. The number of deadly weather events has increased, such as hurricanes(飓风)，wildfires and floods. Scientists say     2     has caused these new patterns is climate change. And they encourage everyone to produce less waste. Other     3     (way) lowering your carbon footprint include walking instead     4     driving, bringing reusable bags to the supermarket, and eating less meat. These actions have many benefits, including less air pollution and CO2 production.

The number of chinstrap penguins in some colonies in western Antarctica     1     (fall) by as much as 77 percent since they were last surveyed in the 1970s, say scientists studying the impact of climate change on the remote region. The chinstrap penguin,     2     (name) after the narrow black band under its head, inhabits the islands and shores of Antarctic oceans and feeds on krill( 磷虾). It is the dramatic declines     3     catch the attention worldwide.

A study, published by the United Nations meteorological agency, states that heat-trapping greenhouse gases—carbon dioxide, methane, and nitrous oxide - have reached an unprecedented level in the atmosphere,     4     contributes to global warming. Researchers discovered that between 1979 and 1990, Antarctica shed     5     average of 40 billion tons of ice mass annually. Climate changes are turning into a severe situation,     6     (impact) marine and land ecosystems.

China, as a big country, plays an important role in environmental protection. It aims not only to get rid of the environmental challenges domestically but also to help other parts of the world achieve     7     (they) climate goals. Investment in China on renewable energy accounts     8     45% of total global investment. Since 2014, China has invested     9     (heavy) in the wind and solar PV projects in the regions along the Belt and Road. Faced with this situation, every country should raise the     10     (aware)of environmental protection.

Earth is most likely experiencing its sixth mass extinction. The planet has been through at least five such disaster     1     , but this is the first one in human history-and the first one with human fingerprints.

A report by the World Wildlife Fund       2     (offer) details about this decline, which has cut the planet's vertebrate(有脊椎的) wildlife populations       3     average of 60 percent in just 40 years. Habitat loss is the main threat     4     many endangered land animals. “Science shows us the cruel     5     (real) that our forests oceans and rivers are suffering at our hands now,” says Marco Lambertini, director of WWF International, in a statement. “Inch by inch and species by species decreasing wildlife numbers and wild places are an indicator of the huge influence and     6     (press) we are putting on the planet.”

“The statistics are     7     (scare), but all hope is not lost,” says Ken Norris, science director for the Zoological Society of London. The report exposes some environmental     8     (problem) around the world, but it also throws light on the ways we can still protect and recover what     9     (leave) .We have an opportunity to design a new path forward     10     allows us to co-exist with the wildlife we depend upon.
