On May 9, James Givens was sitting in the car when he heard what     1     (sound) like a knock. He turned around only     2     (find) a goose pecking at the car door, which was highly unusual seen. He knew that the birds     3     (normal) preferred to observe humans from a distance.

But on this day, the goose appeared to be determined to get his attention and did not stop pecking     4     Givens opened the car door and stepped out. Although     5     (force) to walk away a little out of fear, the bird kept turning around to make sure that he was following. When they finally stopped, Givens realized     6     the mother goose did so — she needed help to free her baby goose that had got     7     (trap) in some balloon string.

Worried that the mother goose would attack him if he got close     8     the baby, Civens called the local chapter of Society for the Prevention of Cruelty to Animals. Unfortunately, they were unable to help right away. Mainly     9     (take) into consideration that the baby goose would not survive the delay, Givens decided to take on the task himself.

The mother goose watched patiently as Givens saved the little bird. As soon as the little goose was free, it ran to its mom. Givens said this was the most     10     (forget) incident in his life!

Cities are diverse ecosystems, and a large number of species share our urban areas. As our city spreads, we need think about     1     it is like for other species to have human neighbors.

Because cities     2     (build) for humans, they do not always provide suitable habitats for wildlife. For example, most city parks are kept neat and tidy so that humans will find them     3     (pretty) than before. But when we cut grass or plant flowers, we destroy natural habitats.

When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length of its bottom,     4     made a good home for bats, and soon the bridge was the home of thousands of bats. At first, people were afraid     5     the bats. Now, they have come to value     6     (they) winged neighbors. The bats are a tourist     7     (attract), and they eat lots of bugs every night.

There are also structures built with the objective of     8     (bring) wildlife into the city. The Beijing Olympic Forest Park is a good example. The park     9     (use) native plants and created open, natural spaces for wildlife. The result is a zone where over 160 species of birds can move about     10     (free). If we learn to share our space, we can become better neighbors to the wildlife around us.

Threatened by Arctic changes

Climate change may wipe out polar bears by the end of this century,    1    recent report in the journal Nature Climate Change said. However, unless more is done, their extinction is likely    2    (come) earlier as their home may disappear.

According to Science Daily, the Arctic, the only natural habitat for polar bears,    3    (be) in danger. Sea ice in the area could disappear    4    (complete) by 2035. This is undoubtedly bad news for this animal, as they use the    5    (float) sea ice to hunt.

Scientists made this    6    (predict) by using the UK climate model. According to Science Daily, this model allowed researchers to compare Arctic sea ice conditions during the last interglacial period(间冰期)    7    present day conditions. Researchers found that during the last interglacial period many shallow    8    (pool) of water formed on the surface of the Arctic sea ice during spring and summer. These pools, known as melt ponds, played a key role in the melting of the sea ice. This is because    9    there are larger areas of melt ponds, more heat is absorbed by sea ice, which causes it to melt    10    (far). To save the northern-most region of Earth, what we should be doing is "focusing all our minds on achieving a low-carbon world".

Pioneering underwater photographer David Doubilet is a master craftsman,     1    combines technology and capture (捕捉) life underwater,         2    (bring) images back to the surface for those who might never see those sights with their own eyes. Entering the sea as a journalist, artist, and         3     (explore), Doubilet documents both the beauty and the   devastation (破坏) in our oceans.

He believes that the photography has the power         4     (educate), and influence change. Doubilet is deeply concerned about the future of the oceans. When he     5       (ask) what sort of powerful stories he’d like to tell through his work, he says, “Right now, we’re   telling the most     6    (meaning) story in the world. Doubilet and his wife, Jennifer Hayes, are working on a National Geographic project     7     (name) “Coral Status, the Science and the Future”.

They are looking at coral worldwide to see how it’s changed, and changing. “A lot of climatologists are thinking coral may be one of     8     greatest indicators (指示者), the thermometer of the health of this planet. We’re looking at reefs that are thousands     9    years old, and in the last four and five years they have     10    (complete) died. That’s what happens when you have a warming ocean.

There     1     (be) no lights in sight but the night sky glowed (发出) a dusky yellow, because the Amazon was burning. The yellow flames engulfed (吞噬) trees     2     lit up the sky. During the day, the sunshine was blocked     3     thick smoke. So far, the fire     4     (put) out.

The government has recorded 72, 843 fires. The fire is just one of     5     (they) in the Amazon, the world’s     6     (large) rainforest and a fighter against climate change. According to Brazil’s space research agency INPE, the wildfire has decreased by 17 percent so far this year compared to the same period in 2018.

Environmental     7     (group)said the policies of the government encouraged deforestation (采伐森林) of the Amazon,    8     led to more fires. But the government posted a report and wanted     9     (argue) against that. The government claimed that non-governmental organizations     10     (angry) set fire to the forest after it cut their funding.

An Italian town will pay people hundreds of euros(欧元) per year if they cycle to work instead of    1    (drive) their cars. The government will pay    2    (cycle)25 cents per kilometre, up to a monthly limit of 50 euros. That means commuters(通勤者)who switch to two wheels could pocket up to 600 euros in a year. It is said to be the first such plan in Italy.

Fifty workers will be included in a 12-month trial, which will use a smart phone app to record the    3    (distant) travelled each day. The plan is being supported from fines    4    (collect) from traffic tickets in the town,    5    by law have to be spent on road safety.

The plan will encourage citizens    6    (make)sure the area becomes more liveable. It will     7    (natural )mean less traffic on the streets and more health benefits. A bicycle organization which helped to develop the idea, says it hopes that other towns will now follow the lead.

A similar plan    8    (introduce)in France in 2014, with mixed results. A six-month trial found that paying people to cycle to work did increase the numbers doing so, but the    9    (major) had been using public transport, rather than private vehicles.    10    those making the move from cars to bicycles, most had already been carpooling (拼车). Private cars remained crowded in the Streets

8 . 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).
