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’s research icebreaker Xuelong,     1     126 crew members aboard on the 35th Antarctic research mission, on Thursday local time left the Zhongshan Station on     2     (it) way back to China.

Snow Eagle 601, China’s first fixed­wing aircraft for polar flight, on Thursday night also departed from the Antarctic after     3     (complete)all assignments.

Xuelong,     4     arrived near Zhongshan on Feb. 9, supplied the station with fuel oil, and then picked up summer expedition   team members   at   the   Kunlun, Taishan and Zhongshan stations, as well as     5    (member)of the fixed­wing aircraft project.

Sixteen members of the Kunlun team     6    (previous)completed all scientific expeditions at Dome Argus (Dome A), the South Pole’s highest icecap. They，together with 21 members of the Taishan team,     7    (return)to Zhongshan on Feb. 8.

The Zhongshan team completed tasks including installation of and tests for LiDAR, drilling of ice bedrock, atmospheric sounding     8    (observe)，surveys of birds and aerial exploration carried out by the fixed­wing aircraft.

As the summer expedition team at Zhongshan left, 19 members would stay for winter expeditions.

Also     9    (know) as the Snow Dragon, the icebreaker carrying a research   team   set   sail   from Shanghai on Nov. 2   last year, beginning     10     country’s 35th Antarctic expedition. It is expected to arrive in Shanghai in mid­March.

There is some good news for the environment. The British government has banned the use of plastic particles (微粒）in cosmetics (化妆品）and other personal care products.

Plastic microbeads or tiny solid plastic particles     1     (use)mostly in cosmetics production, face washes, toothpastes and other products. When we use these things, the plastic microbeads get into our pipes that carry water, and     2     (eventual)end up in the ocean. Plastic in the ocean puts fish and plants     3     danger, and even causes them to die.

    4     (official)say that the ban will prevent water pollution and in the meantime help with the     5    （protect)of ocean life. "The ban will stop billions of pieces of plastic entering our ecosystem, thus     6     (help) to conserve our precious seas and oceans, "Former Prime Minister Theresa May ever wrote on Twitter.

Therese Coffey, then the Environment Minister of the UK, said, "The world's seas and oceans are some of our most     7    (value)natural things. And     8    we do now is to deal with the plastic that causes great damage to our sea life. "He also added, "Actually,     9     amount of natural green things that we can take advantage of     10    (make)personal care products is huge, and therefore the use of plastic microbeads should be abandoned. ”

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.

8 . Global warming is one of the most serious problems facing humans and greenhouse gases are the main cause of it. Greenhouse gases are produced not only by industry but also by individuals (个人). People use energy to drive cars, make homes     1     (comfort) and grow and transport food. Finding     2     (solve) to the problem of greenhouse gases is not only a political subject but an individual one as well.

Look for ways     3     (reduce) energy at home. Turn off electrical appliances (家用电器) that you are not using. Replace your light bulbs with energy-efficient light bulbs.

Eat locally. A lot of energy     4     (use) to transport food over long distances,    5     burns much fuel. Much of the same food may be grown on local farms. Shop at your local farmers, market. Plant your own vegetable garden.

Make your house     6     eco-friendly one. Put a sweater on to keep warm rather than turning the heating on. Plant a tree to provide shade in summer so you don’t have to use an air conditioner.

Reduce and recycle. Be careful     7     the products you buy. Recycle all paper, plastic, glass and aluminum (铝) cans.    8     (when) you go shopping, please choose items that come with small packaging and that     9     (be) reusable. Use your own canvas bags for shopping instead of plastic or paper bags.

Be energy-conscious of transportation. Walk, ride a bike     10     take a bus instead of driving.

9 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).
