For many years, human beings have been trying to conquer nature, but never succeeded. What’s worse, nature has got angry. It often shows     1     (it) power and teaches human beings different lessons in various     2     (way), such as earthquakes, floods, hurricanes, sandstorms, typhoons, droughts, landslides, tornadoes, and volcanoes. Any of them can cause terrible disasters. For example, on March 11, 2011,     3     huge earthquake struck Japan,     4     (cause) a terrible tsunami. Many cars, ships and buildings     5     (ruin) by a ten-metre-high wall of water. Thousands of people were confirmed dead. The total energy released by the quake was equivalent to the explosion of 6.7 trillion tons of TNT,     6     is about a thousand times the total power of all the world’s nuclear weapons. Another event was the “huge volcanic eruption in Iceland” in 2010. It caused enormous damage to air travel across western and northern Europe because     7     the large quantities of volcanic ash. All of these show how     8     (power) nature is.

Compared with the great power of nature, human beings are so weak and even so helpless in face of the destruction caused by natural disasters. It would be unwise of us     9     (fight) against or even try to conquer nature. On the contrary, we should try to learn how to live with nature     10     (peaceful).

The Dujiangyan Irrigation System is located on the Minjiang River, in the western part of the Chengdu Plain. Constructed around 256 BCE, it remains the world’s     1     (old) irrigation system still in use today.

When the annual floods of the Minjiang River caused enormous suffering, the governor Li Bing was so concerned that he made a     2     (decide) to solve the problem. Li Bing and his son carefully studied the flow of the river and the terrain (地形,地势) of the plain.     3     (Draw) on the water management experience of previous generations, they led the local people to construct an irrigation system. Instead of building a dam,     4     would have blocked boat traffic, they decided to make full use of the terrain and split the river     5     (spread)out the flow of water. Since there was no     6     (advance) machinery, tens of thousands of workers used rocks to alter the course of the river. When the water needed to be diverted (使绕道) through a mountain, they employed a creative technique: exploding the rocks     7     heating them with fire and cooling them down quickly.

The Dujiangyan Irrigation System took almost a generation to complete. Since then, it     8     (manage) the waters of the Minjiang River and allowed local agriculture to develop, ensuring     9     plentiful supply of food. This milestone in the history of water management is the living proof     10     with innovation and determination ancient Chinese people made nature work to their advantage.

Three sites in China˗˗an ancient tea-producing area, a nomadic livestock-rearing region and a rain-fed stone terrace farming system˗˗were formally recognised as Globally Important Agricultural Heritage Systems (GIAHS), for their unique ways of using traditional practices and knowledge while maintaining unique biodiversity and ecosystems.

An ancient tea-producing area (中国福建安溪铁观音茶文化系统)

Tea production in Anxi, Fujian, is believed to date from the 10th century, with its most famous tea, Tieguanyin, coming into    1     (exist) in the 18th century. It belongs to the Oolong tea category between green tea and black tea. Local farmers’ unique technique includes wisely managing the natural environment to guarantee the production of     2     exceptional quality tea leaf.

A Grassland nomadic system (中国内蒙古阿鲁科尔沁草原游牧系统)

The Ar Horqin grassland nomadic system in northern China’s Inner Mongolia region has a variety of ecosystems, such as forests, grasslands, wetlands, rivers with important ecological     3     (function). To adapt     4     the fragile grassland environment, the ancestors of today’s herders (牧民) adopted a typical nomadic lifestyle. By    5     (constant) moving grasslands, they ensured the protection of vegetation (植被) and full use of water resources,    6    (avoid) soil degradation (恶化) and overgrazing and bringing a steady supply of livestock products.

The Shexian Dryland Stone Terraced System (中国河北涉县旱作石堰梯田系统)

The Shexian Dryland Stone Terraced System in Hebei, is a rain-fed agricultural system dating back to the 13th century.     7     (surround) with mountains, the stone terraced fields still play an important role in making     8     possible to farm on the steep slopes. The county is well-known for corn, soybean and other agricultural and forestry products. With this variety of crops and farming techniques, local communities     9    (manage) to guarantee their food security and well-being over hundreds of years, while shaping a remarkable landscape     10     bears witness to their ability to live with their environment.

Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free by spreading on them cheese brine, the salty liquid     1    (use) to make soft cheeses, like mozzarella(马苏里拉奶酪).

Wisconsin, also called “America’s Dairyland”, is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! As a result, there     2    (be) a lot of leftover cheese brine.     3    (dispose) of the brine can be expensive. So what should cheese makers do     4     the waste?

Cheese brine has salt in it,     5    , like the rock salt, helps lower water’s freezing point.

    6    (normal), towns use rock salt to de-ice streets. The salt lowers water’s freezing point, causing ice     7    (melt). But using cheese brine could help both cheese     8    (produce) and cities save money, while keeping roads safe.

In addition to saving money, cheese brine could also be a more eco-friendly option. Many people suspect that all the rock salt used every winter     9    (harm) the environment, because road crews spread about 20 million tons of salt on U. S roads every year!     10    , by spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.

Carved from mountains in Yunnan province, the Hong-he Hani Rice Terraces reach over more than 160 square kilometers to create a most spectacular landscape.

Since ancient times, the local Hani people have channeled spring water from mountains and forests     1     (water) the terraced fields. Some terraces are as big as football fields, and others no larger than a bed sheet. They climb     2     riverbank locations at less than 500 meters above sea level to heights of more than 1,800 meters. The     3     (common) used description “stairways to heaven” is most suitable here.

However, the wonder remained largely unknown to the rest of the world for     4     (century). Nobody paid much attention to these terraces until     5     2000s. New roads arrived and the local government was determined to get the terraces     6     (place) on UNESCO’s World Heritage List. This     7     (achieve) in 2013. Over the past decade, it has become impossible to keep such a wonder under wraps. Photography fans have crowded in, taking postcard-perfect pictures and then     8     (post) them on social media.

Although the terraces shine with bright green during the summer growing season, the landscape is most     9     (appeal) from November to late April. During this period, the water-filled terraces turn into natural mirrors     10     reflect every sunrise and sunset.

Human voices cause much more fear in wild animals than the sound of lions, a study in South Africa has found. Scientists played recordings of people talking     1     (normal) through speakers in the Kruger National Park. About 95% of the animals     2     (be) extremely frightened and quickly ran away. In contrast, recordings of snarling and growling lions caused obviously     3     (little) alarm. During the experiment, they noted, that some elephants, in response to the big cat calls, even attempted     4     (face) the source of the sound.

According to the study, the animals have learnt that contact with humans is extremely     5     (danger) . The fear exhibited goes beyond the Kruger National Park, as a global pattern shows wildlife tend to fear humans more than any other predator (捕食者). The authors note that this creates a challenge for areas,     6     rely on wildlife tourism, because the human visitors they want to attract are unintentionally scaring off the animals they have come to see.     7    , the findings open up the possibility to protect weak species. Human sounds, when     8     (use) properly, could help protect against illegal hunting. “Now we     9     (work) together in experiments, testing whether we can prevent rhinos     10     hunting hotspots,” one of the authors said.

Chengdu is regarded by many as one of the happiest cities in China, as well as the home of pandas. It     1     (become) the first Asian city to be identified as a UNESCO City of Gastronomy in 2010.

Chengdu is a place where it seems to blur (难以区分) the boundaries between past and future. Its ancient temples, traditional alleys and historic architecture open a window into ancient China,     2     (take) you into a world of past impressive beauty. But what is really surprising is its focus on the future. Transforming into a center of technology, innovation and development, this city has     3     (ambition) plans to become a science city in southwest China.

Chengdu is not only rich in history and modernity, but also in flavor. This city is known     4     its spicy food, with bold flavors and centuries-old cooking traditions coming together to offer dining experiences     5     will delight all the senses. Chengdu’s most popular food, such as tongue-numbing mapo tofu and hotpot, is     6     feast for the palate (味觉). Hotpot works like this. A heat source     7     (place) on the dining table keeps a pot of soup stock simmering (煨), and a variety of Chinese foodstuffs and     8     (ingredient) are served beside the pot for the diners to put into the hot stock.

All this richness that Chengdu has to offer led to its selection as the host city for the 31stFISU World University Games. The athletic event was an opportunity not only     9     (show) Chengdu’s sporting spirit, world-class infrastructure,     10     (warm) and organizational skill, but also to promote friendship and cross-cultural understanding.

Meat, milk, cheese—just some of the things provided by goats. But now we can also add fire safety to this list. Wildfires     1     (make) possible by hot, dry weather conditions as well as a supply of dead vegetation that serves as fuel. We may have limited control over the first factor,     2     we can control the second. Reducing the fuel load lowers the probability of wildfires occurring, as well as the amount of damage     3     (cause). This is where we can turn to goats to provide a     4     (solve). Goats have a very digestive system. Much vegetation that are toxic (有毒的) to other animals can be eaten by goats. It’s not just fully-grown plants     5     goats are able to deal with: any seeds that pass through ago at will not grow. Human clearance teams worry about     6     (send) to hard-to-reach vegetation patches (土地) goats don’t. They are     7     (skill) mountain climbers and when standing on their legs, can reach up to two meters to eat shrubs and grass that humans would struggle     8     (reach). Because of this, using goats can reduce both workplace accidents and the amount of money spent     9     fire protection measures. Goatherd shave been found to clear some patches of land for     10     third of the price of human vegetation control teams.

China will closely track     1     assess the impacts of Japan's "extremely selfish and     2    (responsible) " plan to discharge nuclear-contaminated water into the ocean, the National Nuclear Security Administration said.

Japan's plan prioritizes its own interests     3     the long-term well-being of humanity, the administration said in     4     media release on Thursday, the same day that Japan is set to start releasing     5     (treat) radioactive water into the Pacific Ocean     6     part of its plan to decommission the crippled Fukushima Daiichi Nuclear Power Plant.

Japanese Prime Minister Fumio Kishida     7     (give) the final go-ahead for the plan to gradually release more     8    1 million metric tons of radioactive water from the plant into the ocean at a Cabinet meeting on Tuesday.

"We urge the Japanese government to listen to the voice of the international community and     9     (effective) dispose of the nuclear-contaminated water in a     10     (science), safe and transparent manner under strict international supervision," the administration said.

Prince Llewellyn the Great was ruler of Wales for 40 years but he is now remembered more for the story of Gelert. One day, Prince Llewellyn was out hunting in the Welsh countryside. Back home, his newborn son     1     (sleep) as Gelert, his     2     (faith) dog, watched over him. While the Prince was riding through the forest, he heard loud barking     3    (come) from the direction of the house. The Prince had a terrible feeling and galloped quickly home.
