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.

3 . If you visit Uluwatu temple in Bali, be cautious. The long-tailed temple monkeys there are well-known thieves. Since a long time ago, they have made a living by robbing visitors of their possessions and then holding those objects until a ransom in the form of food is paid. But Jean-Baptiste Leca of the University of Lethbridge, in Canada, wondered whether these monkeys are cleverer still. Sometimes, they do not accept the first offer and hold out for more. He therefore asked himself whether they are able to assess how valuable an object is to its owner, and factor that into their negotiations.

Dr. Leca and his colleagues conducted their experiment by wandering around the temple with video cameras, recording the activities of the monkeys. Every time they saw a monkey show interest in a particular tourist? they recorded the interaction. To work out what was going on, they had first to establish the relative values of food rewards to monkeys, and of stealable objects to people.

To confirm which stealable objects are most valued by people, they divided them into six classes: empty containers, such as phone cases and plastic bottles; accessories (搭配物) such as hairpins and key rings; hats and shoes; spectacles and sunglasses; and electronics and wallets. They then observed how often victims bothered to bargain with the thief for the return of property belonging to different classes, and thus classified objects into low value, medium value and high value.

They found that monkeys do, indeed, have a complicated sense of what they are doing — at least, adults and sub-adults do. These animals have a preference for stealing high-value items, and will often hold out either for more rewards, or for better ones, if they are in possession of such items. But this is something that they have to learn how to do as they grow up. Young monkeys make no such distinctions, and sub-adults are less good at doing so than adults.

1. What is the purpose of Leca's research?

A．To prove monkeys are cleverer than men.

B．To find out what is valuable for monkeys.

C．To record the negotiations between monkeys.

D．To make sure monkeys can judge item values.

After new measurements, China and Nepal have announced a new official height for Mount Everest. The result     1     (announce) on Tuesday that Everest’s peak stands 8,848.86 meters tall,     2     (high) than previously thought. It was reported during an online video event     3     (lead) by the foreign ministers of China and Nepal.

The two countries agreed to the official height after new     4     (survey) of the mountain in 2019 and 2020. Everest’s height was first declared as 8,842 meters by a British team around 1856. But the most     5     (wide) accepted height has been 8,848 meters decided by the Survey of India in 1954.

Nepal had never previously measured the height of Mount Everest     6     its own. In 2005, a Chinese team reported height of 8,844.43 meters, not including the mountain’s snow top. A Nepal government team of climbers and surveyors climbed Everest in May 2019, using GPS and satellite     7     (equip) to measure the peak. Later that year, the leaders of the two countries decided they should agree on     8     official height. A survey team from China then carried out measurements in the spring of 2020, during     9     time all other climbing activities had stopped because of the coronavirus crisis.

Nepal’s climbing community welcomed the result. “The height of Mount Everest will not be a conflict     10     a mutually agreed number. This is a milestone in mountaineering history,” said Santa Bir Lama, president of the Nepal Mountaineering Association.

5 . The latest thing in architecture is green buildings—covering walls and roofs with a carpet of plants to prevent heat, absorb rain and provide a home for wildlife. Many such buildings need complex systems for holding and irrigating the soil.    1    

Ivy is a group of evergreen climbing plants, whose power to live is hard to beat. Firstly, it can live in almost any surroundings, whether in shade or full sun.    2    It grows well in both dry and damp soil. Moreover, it doesn't need supports as it grows aerial roots that can be attached to most things. For these reasons, ivy can be widely grown to beautify an ugly wall or a fence.    3    It is a heaven for bees and butterflies in summer and its berries are a valuable food source for birds in winter.

However, there are some concerns about growing ivy. Ivy has a reputation for damaging buildings, but according to the UK's Royal Horticultural Society, this doesn't usually happen unless the walls already have cracks.    4    But Blanusa at the University of Reading, UK, who has examined the effects of plant climbers, finds that ivy raises humidity next to the wall by only a small amount.

    5    Once ivy has been in the ground for a few years, it can grow out of control. Just don't let it get the better of you.

A．Growing ivy can bring added benefits.

B．Therefore, I strongly oppose growing ivy.

C．The other fear is that it can make walls damp.

D．Besides, it can be tolerant of various kinds of soil.

E．Anyway, you do need to be careful in growing ivy.

F．An ivy-covered wall will slightly warm a room in winter.

G．However, there is a much easier approach: growing some ivy.

6 . Bees are essential for the pollination of flowers, fruits and vegetables. Sadly, over the past 15 years, the global population of the hardworking insects has been dropping worldwide at alarming rates due to loss of food and habitat. Now, Dutch cities are coming up with creative ideas to help stem the population decrease of these all-important insects.

In Amsterdam, bees can live for free in specially built “hotels” — tall wooden structures — across the city. While they may not look like much to the untrained eye, they provide perfect homes for members of the over 200 known species of solitary bees. As the name indicates, the insects spend their lives alone. The smart insects nest inside holes like the ones provided by the insect hotels, marking their occupancy by covering the entrance with a mud “door”. Though unable to produce honey, solitary bees are excellent pollinators and perform an essential role in many ecosystems.

Additionally, city officials are also educating people on the use of harmful chemicals and are providing prize money to encourage developers to build green roofs and populate them with local plants. In 2015, they set a goal to change some plants in public green spaces to native plants. Geert, one of eight ecologists working for the city, says, “Our idea is when we design a park, we use native species but also the species that give a lot of flowering and fruit for bees.” Many people, with help from the government, are replacing the sidewalks outside their homes with small gardens featuring flowers.

In Utrecht, bus stop roofs are gradually being turned into beautiful, living gardens designed to attract varieties of bee species. The green roofs, which naturally collect both rainwater and dust, are also beneficial for the environment.

These cities’ collective efforts seem to be working. A recent study found that the variety of bee species there has increased by an astonishing 45 percent since 2000.

7 . The Ebro Delta,known as,a battleground during the Spanish Civil War,is now the setting for a different contest,where rice farmers fight against two enemies:the rice-eating giant apple snail,and rising sell levels.What happens here will have an effect on the future of European rice production and the overall health of southern European wetlands.

Located in the Western Mediterranean,the Ebro Delta produces 120 million kilograms of rice a year,making it one of the continent’s most important rice-growing areas.As the sea moves into these fresh-water marshes(湿地),however,rising salinity(盐分)is hindering rice production.At the same time,this sea-water also kills off the greedy giant apple snail,an introduced pest that feeds on young rice plants.The most promising strategy has become to exploit one evil against the other.

The battle is currently in progress on land,in greenhouses at the University of Barcelona.Scientists working under the guidance of”Project Neurice”are seeking varieties of rice that can withstand the increasing salinity without losing the absorbency.

“The project has two sides,”says Xavier Serrat,Neurice project manager and researcher at the University of Barcelona,”the short-term fight against the snail,and a mid-to long-term fight against climate change.But the snail has given the project greater urgency.”

Originally from South America,the snails were accidentally introduced into the Ebro Delta.For now,the giant apple snail’s presence in Europe is limited to the Ebro Delta,But the snail continues its march to new territory,says Serrat.”The question is not whether it will reach other rice-growing areas of Europe,but when.”

1. What’s the most effective strategy according to Paragraph 2?

A．Beating enemies one by one.	B．Striking the stronger enemy first.
C．Killing two birds with one stone.	D．Using one enemy to hit the other.

A．It puts the control of snails first.

B．It functions pretty well on climate change.

C．It aims to increase the Spanish rice production.

D．It stresses the snails’effect on rice production.

3. What can be known about the apple snails from the text?

A．It can tolerate the rising salinity.	B．It will attack other rice-growing areas.
C．It multiplies at a high speed.	D．It was introduced into Span deliberately.

4. Which section is the text most likely from?

A．Chemistry.

B．Tourism.

C．Farming.

D．Geography.

Brownie and Harry were neighbor dogs in Stowe, a beautiful and peaceful town in Lamoille County, Vermont, United States, who met everyday to play together, running after each other joyfully. Like pairs of dogs you can find in most any neighborhood, these two loved each other and played together so often that they had worn a path through the grass of the field between their respective houses.

One evening, Brownie's family noticed that Brownie hadn't returned home as usual. They went looking for him with no success. Brownie still didn't show up the next day, and, despite their efforts to find him, by the next week he was still missing.

Curiously, the other dog, Harry, showed up at Brownie's house alone one day. He barked, jumped and pestered(纠缠) Brownie's human family, showing that he was filled with anxiety. Busy with their own lives, the family just ignored the nervous little neighbor dog and decided to let the missing dog go.

Harry refused to take “no” for an answer. Ted, Brownie’s owner, was steadily disturbed by the angry, determined little dog. One morning Harry followed Ted about, barking more insistently, then rushing toward a nearby empty lot and back, as if to say, “Follow me, please!I's very urgent!”

Eventually, Ted went after the mad Harry across the empty lot as Harry paused to race back and bark encouragingly. The little dog led the man under a tree, past some tree jungles, to a lonely spot a half mile from the house. There Ted found his beloved Brownie, and he was alive, with one of his front legs falling into a steel trap. At that moment, Ted understood the strange behavior of Harry.

Feeling regretful, Ted now wished he had taken Harry's earlier appeals seriously. However, Harry had done more than simply led Brownie’s human owner to his trapped friend. Ted noticed something quite remarkable before him and was shocked that the amount of love that the dog has for his partner could be so outstanding.

Paragraph 1:

In a circle around the injured dog, there were some remains of meals.
