A male elephant that broke away from the wandering elephant pack     1    ( send) back to its forest home on Wednesday in Xishuangbanna Dai Autonomous Prefecture, southwest China's Yunnan Province, local authorities said.

Yuxi City headquarters in charge of monitoring the pack's migration (迁徙) took the     2     (decide) early Wednesday morning     3     ( prevent) the lone animal from entering heavily populated areas. At 3 p. m.，the elephant was caught and returned to the nature reserve. The animal appeared     4     (health) and did not suffer from any injuries.

The pack of 15 wandering wild Asian elephants travelled about 500 kilometers north from their forest home. The male elephant separated from the pack on June 6, and moved around in the     5     (city) of Kunming, Anning and Yuxi, with an activity area of 140 square kilometers and a walking distance of 190 kilometers. It had relied mainly on     6     was provided by the locals. The     7    (remain) 14 elephants have been moving southward recently but are still far from the reserve.

Asian elephants are     8     A-level state protection in China, where they are     9     (most) found in Yunnan. Thanks to determined protection efforts in recent decades, the wild elephant population in     10     province has grown to about 300, from 193 in the 1980s.

As we all know, the pollution of air, water and soil are the most serious problems. The     1     (pollute) air, which causes diseases and deaths, does great harm     2     people’s health. What’s more, vegetation (植被) has been greatly reduced with the rapid     3     (develop) of the modern city.     4     (protect)the environment, governments of many countries have done a lot. In the past few years, legislative (立法的) steps     5     (introduce) to control air pollution. Governments are playing the most important role in     6     (environment) protection today. In my opinion, the government must take even more concrete measures. First, it should let people fully realize     7     importance of environment through education. Second, much more efforts should be made to put the population planning policy into effect, because more people means more pollution. Finally, those     8     destroy the environment intentionally (有意地) should be     9     (severe) punished. Everyone should be aware that     10     (destroy) environment means destroying mankind themselves.

4 . Japanese botanist Akira Miyawaki, beginning in the 1970s, pioneered a method of planting young native species close together to quickly create tiny forests on urban wasteland. He found that protected areas around temples in Japan contained a huge variety of native plants that co-existed to produce adaptable and diverse ecosystems. The forests were layered together from four categories of native plantings: main tree species, sub-species, bushes, and ground-covering herbs. Using this four-category system, along with his explorations of the vegetation in Japan, Miyawaki designed his own system for planting forests.

Miyawaki forests can grow into mature ecosystems in just 20 years-about 10 times the growth speed of a traditional forest, explained Kazue Fujiwara who worked with Miyawaki. According to Fujiwara, the planting should center on the primary trees of the location. Native species require no maintenance (养护) after the first two years and are more likely to survive and grow well in the local environmental conditions. What's more, they provide an ideal home for endangered species.

When Shubhendu Sharma learned about Miyawaki's forest creation technique in 2009, the botanist created a forest at the Toyota factory in India where Sharma worked as an engineer. Shortly, he started a company to create similar forests, researching the method and trying it in his own backyard. He described his work in a 2014 TED Talk, and released his version of the instructions so anyone could learn how to create their own small native forest. Since then, Sharma's company, Afforestt, has helped plant forests in 44 cities.

Now, Miyawaki-style urban forests have been springing up across Europe. Cities in Asia are embracing the idea, with Pakistani minister announcing plans for 50 Miyawaki forests in Lahore, and Indian officials setting a target to plant 1,000 in Chennai.

The worst thing about plastic straws (吸管) is that most of the time, they’re not a     1     (choose). Like much of the single-use plastic that     2     (come) our way, they just appear, placed in take-out bags or     3     (provide) with iced tea. And if you pick up plastic on beaches, you know that one of the most common pieces of plastic waste you’ll find is plastic straws. They’re everywhere. And once they make     4     (they) way to the sea, they’re eaten by fish or birds that mistake them for food. Straws are used once and then they are immediately thrown away and become waste, staying in the environment     5     years.

    6     (fortune) , we can do something to help. If you like to use a straw at home     7     you want to provide them at your business, there are two options. The first one is trying a reusable straw, which can     8     (wash) along with dishes. They come in stainless steel or glass. And they come in all kinds of sizes and some have fun decorations.

Another option is paper straws,     9     also come in all kinds of pretty decorative colors and patterns. You can even find them     10     (make) from recycled paper!

With so many options available, there’s no reason to add to the plastic straw waste problem.

10 . A report has warned of a “destructive” decline in freshwater fish, with nearly a third threatened by extinction. Conservation groups said 80 species were known to have gone extinct, 16 in the last year alone.

The report said populations of migratory fish have fallen by three-quarters in the last 50 years. Over the same time period, populations of larger species, known as “megafish”, have crashed by 94%, In UK waters, the sturgeon and the burbot have disappeared, salmon are disappearing and the European eel remains extremely endangered.

According to the WWF, much of the decline is driven by the poor state of rivers, mostly as a result of pollution. Besides, dams and waste water are also the factors. It has called on the government to restore freshwater habitats to good health through proper carrying out of existing laws, strengthening protections in the Environment Bill and championing a strong set of global targets for the recovery of nature.

Dave Tickner, from WWE, said freshwater habitats are some of the most full of life on earth, but as this report shows they are in “destructive” decline around the world. “If we are to take this government's environmental promises seriously, it must get its act together, clean up our rivers and restore our freshwater habitats to good health,” said the organization's chief adviser on freshwater.

Carmen Revenga of The Nature Conservancy said freshwater fish are a diverse and unique group of species that are not only important for the healthy functioning of our rivers, lakes and wetlands, but millions of people, particularly the poor, also depend on them for their food and income.

“It's now more urgent than ever that we find the collective political will and effective cooperation with private industries, governments, NGOs(Non-Governmental Organizations) and communities, to carry out nature-based solutions that protect freshwater species, while also ensuring human needs are met,” she said.
