High on the Qinghai-Tibet Plateau     1    (lie) China’s “water tower” Sanjiangyuan. It is home to the headwaters of China’s three rivers: the Yellow River, Yangtze River, and Lancang(Mekong) River. It is the three rivers     2     provide water for about half the population of China. However, human activities are putting this ecosystem     3     risk. Hopefully, though, we can repair this damage. In 2016, the Chinese government established Sanjiangyuan National Park in Qinghai province. The park,     4    (schedule) to open in 2020, has increased the area’s green coverage and attracted more wildlife. The local government has also made great effort to improve biological diversity. The success of Sanjiangyuan will mark the start of a     5    (green) future. With Sanjangyuan     6    (take) the lead, nine other regions in China     7    (choose) by a field conservation station to carry out projects over the past three years,     8     will form a national park system together.

2 . Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.

Traditional migration paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.

The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.

The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.

The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.

One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.

He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

4 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

A．Walking is good for your health.

B．Try to cut back to save water and energy.

C．But you can pack healthy food from home.

D．Travelling is a great chance to introduce your kids to the world.

E．Reusable water bottles are easy to bring along wherever you travel.

F．Save energy by turning off the hotel room lights when you head out for the day.

G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile.

5 . Every year from March to October, Christian Moullec, also known as “Birdman,” takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks (鸟群) of lesser white-fronted geese (小白额雁) through safe migration paths which the birds can teach future generations.

His deed began in 1995 when he noticed their declining population in the wilds of Lapland, Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.

However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth.

To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castles and cities.

He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds, with more than a third disappearing in the last 30 years. “It's a disaster,” he said. “My beautiful images with flying birds should be used to tell this story. ”

6 . When we think of bicycles, we think of fun and the outdoors. Bicycles give riders the freedom to explore and enjoy the environment and its surroundings.     1    

Most people know that riding bicycles is environmentally friendly.     2     If you are riding a bike, you are helping to reduce air and noise pollution.

Bikes are becoming more and more popular across the world. In fact, they are becoming more than just a fun pastime (娱乐).     3     For many people around the world, access to markets and schools would not be accessible without a bike.

    4     Some cities, such as Paris and Barcelona, have not only built bicycle lanes but also have introduced a system of renting bikes. You can rent, or use a bicycle in one area of the city and drop it off in another area of the city. Paris now has thousands of bikes for public use, with bicycle stations located throughout the city.

Some South American cities, such as Bogota in Colombia, have a weekly car-free day.     5     On these days, the traffic-related air pollution from old buses and trucks is greatly reduced.

It seems that the bike is a force for good, providing solutions for cleaner cities without leaving a serious environmental footprint.

7 . 阅读短文内容，在空白处填入1个适当的单词或括号内单词的正确形式。

Earlier 2019,the International Center for Integrated Mountain Development published    1    most comprehensive analysis up to now of how climate change will affect the glaciers of the world,    2    (warn) that about 18,00 glaciers(冰川) will disappear by 2100.

This is a bad    3    (predict) for some 1.9 billion South Asians,    4     use water from the glaciers not only for drinking but also for agriculture, hydroelectric power,and tourism. But the survey also looked at an immediate question: As the glaciers     5    (rapid) melt, where will all the water—more than a quadrillion gallons of it, almost the amount    6    (contain) in Lake Huron—go?

The answer is that the Himalaya, for example, long defined by    7    (it) glaciers,is becoming a mountain range defined by lake. In fact, another study found that from 1990 to 2010, more than 900 new glaciers-fed lakes     8    (form) across Asia's high mountain ranges.Because of those remote locations scientists must rely    9    satellites to count them ,and new lakes appear to be growing so quickly that it's difficult for scientific teams to agree on the precise number. I's all happening much    10    ( fast) than we expected it to even five or ten years ago.
