Diets have changed in China — and so too has its top crop. Since 2011, the country     1    （grow）more corn than rice. Corn production has jumped nearly 125 percent over     2     past 25 years, while rice has increased only 7 percent.

A taste for meat is     3     (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice     4     (improve) water quality. Corn uses less water     5     rice and creates less fertilizer(化肥) runoff. This switch has decreased     6     (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

According to the World Bank, China accounts for about 30 percent of total     7     (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government     8     (start) a soil-testing program     9     gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while     10     (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.

China has formally made an announcement of its first five national parks of 230, 000 from Tibet to Hainan, focusing on     1     (preserve) of its most valuable bio-resources.

Giant Panda National Park will surely be     2     hit with the swells of tourists who come yearly for some of the world’s cutest animals.     3     (cover) three provinces (Sichuan, Shaanxi and Gansu), the region is the panda’s natural habitat.

The intersection (交汇处) of Jilin and Heilongiang provinces is home to Northeast China Tiger and Leopard National Park, which     4     (set) out to protect the habitats of those two species since its start. It is the unique area       5     live both wild Siberian tigers and Siberian leopards.

China’s best-preserved rainforest is in Hainan, the only place in the world     6     (find) the Hainan black-crested gibbon(黑冠长臂猿). Hainan Tropical Rainforest National Park protects the gibbons and     7     (they) environment.

Unlike those three, Wuyishan National Park in Fujian Province and Sanjiangyuan National Park on the Qinghai-Tibet Plateau focus     8     (much) on preserving multiple animals than     9     (specific) protecting one species. They serve various rare and endangered species and conserve biodiversity.

Now, with some tourist programs     10     place, these parks will be a good way for tourists to truly experience the natural originality as well as expansive Chinese landscape.

China will build the world’s largest national park system, and a layout plan will be released soon. The plan is being drafted     1     (meet) the requirements of building a system with the largest scale of protection, the most diverse geographical features and the highest conservation value in the world. Under the plan, which     2     (launch) by the administration in 2019, about 50 areas have been selected as candidates for national parks. The parks are expected to cover 10 percent of the     3     (country) land area and preserve more than 80 percent of the key national     4     (protect) wild plant and animal species. In October, China announced its first group of five national parks, covering     5     total land area of more than 230,000 square kilometers. Since their establishment, the parks     6     (make) achievements in environmental and species protection. “At the same time, a new group of national parks are being established     7     an orderly manner and will be put into use as soon as possible,” emphasized Li,     8     was the National Forestry and Grassland Administration official. He also said at the news conference on Monday China’s planted forest conservation area has reached 87.6 million hectares,     9     (rank) No.1 in the world. “China is also one of the 12 countries with the     10     (rich) biodiversity in the world,” he added.

Nowadays, the life of many people in the world     1     (affect) by global warming. For example, greenhouse gas has a bad effect     2    both people and environment. The earth’s surface temperature     3     (go) up by about 1 degrees centigrade in the past 100 years. As a matter of fact, we may feel that we can hardly put up with the extremely hot summer and we can’t get     4     (accustom) to warm winter. The rise of the earth’s surface temperature has affected human health, the existence of creatures     5    the balance of ecosystems. There is no doubt     6     it is human activities that result in the bad environment. As a     7    (consequent), conditions permitting, all countries in the world should spare no effort     8    (improve) our environment. Even if our effort is limited, it will     9     (eventual) make a great difference if we keep on     10     (work) together to deal with global warming. Without all people’s joint efforts, what would our future be like?

The earth’s plants     1     animals become endangered every day. And many of them are     2     (die) out. If nothing is done, we may find     3     (our) alone on the earth.

Wild animals live in the forests     4     are being destroyed by people. As a result, the animals are losing their habitats. Besides, animals are short of food because of     5     (pollute). Even     6     (bad), buying leads to killing, too.

I suggest that measures should be taken     7     (protect) wildlife. First, we can try to raise people’s awareness to love animals, for they are our     8     (friend). Then the government should make laws, if someone hunt, they must     9     (punish). If we do so, I am sure humans can live in harmony     10     animals.

China's online food delivery platform Ele.me has carried out a new service of picking up garbage from its users in Shanghai     1     July 2019.

The service comes after     2     recently-released regulation on waste management in Shanghai. Individuals     3     throw away their garbage without sorting it can be fined up to 200 yuan, while companies and     4     (organize) can face fines up to 5,000 yuan.

The trash taking service requires residents to sort     5     (they) own garbage before it     6     (pick) up by workers from Ele.me, who will ensure the waste is disposed of in the correct garbage bins.

It's obvious that this service is     7     (convenience) to the old, especially to the disabled customers.

However, many netizens on Sina Weibo don't think Ele.me is providing a wonderful service, saying it just wants     8     (make) money. They think 12 yuan for an order is too much.     9    , many more people doubt if these collectors will wash their hands after dealing     10     the trash.
