1 . Open an app at your smart phone and scan the code bar on the garbage can. When you throw garbage into the garbage can, it will show the weight of the garbage and the points you can get from doing so.     1     It will become more popular in the future. Yes, we are talking about the smart garbage can.

    2     The environmental problems have become constant headaches in the development of those cities. Encouraging garbage classification has become an effective way.

In some cities, a variety of multifunctional smart garbage cans are being put into use. In Beijing, for example, a smart garbage can is equipped with an LED screen, which not only shows national policies on garbage classification but also shows the correct steps for garbage sorting. It can also calculate the weight of the garbage and the accumulated points one can get. They can be traded for some articles of daily use.     3     Its body is actually a screen. It is equipped with some Internal sensors. When people throw garbage into it, the internal sensors can automatically tell the types of the garbage. Meanwhile, people can see how to deal with them.     4    

Garbage disposal is a small issue that involves everybody each day. However, it is also a big issue.    5     With smart garbage cans in our daily life, the idea of garbage sorting will become more established. Our dream of building a greener and more beautiful China will come true so long as we start to make small changes right now.

A．Garbage sorting has been a new fashion.

B．Another kind of garbage can is even smarter.

C．It is no wonder that residents cheered for their presence.

D．Such a way of handling garbage has appeared in some cities.

E．It will affect China’s transformation towards green development.

F．Over 200 million tons of garbage is produced each year in some cities.

G．The good habit of garbage classification can improve the living environment.

2 . Located in the southeast of Canada and with a population of approximately 6 million, Toronto is a big and beautiful city, which has developed from a relatively unknown place over the past half century to the center of culture, trade and communication in Canada.

With its colorful ethnic mix, rich history and breathtaking buildings. Toronto offers non-stop adventures to the tourists. To get a sense of how big, various and magical Toronto is, the best place to start is the CN Tower. From this point, visitors can get a bird's-eye view of the city's amazing scenery and unique geography.

In addition to being an important center of culture, trade and communication in Canada, Toronto is also a major muti-ethnic city. It is the most populous city in Canada and its citizens come from countries around the world and from different kinds of ethnic backgrounds. Every day, in most places of the city, a hundred different languages can be heard on the streets, from Hindi to Greek to French. This, perhaps, explains why former Prime Minister Pierre Trudeau once said that Canada is a mosaic（嵌合体）of cultures and languages rather than a melting pot.

Street signs in Toronto are mostly in English. Weekly and daily newspapers are published in various languages, and the city hosts the successful international film festival each September. It is also home to a popular baseball team the Toronto Blue Jays. Toronto has something for everyone.

Moreover, Toronto has been rated one of the most livable cities in the world by United Nations Human Settlements Programme for many years. At the same time, Toronto is one of the safest, richest cities in the world with the highest standard of living.

Climbing Mount Everest was once a feat(壮举) reserved for only the bravest mountaineers.These days even inexperienced or elderly climbers try to get to the top of the world.

Twenty years ago, climbers in their 60s     1     (have) just a one-in-eight chance of getting to Everest's summit(峰顶), but now the odds are closer to one in three.

The fortunes of first-time Everest climbers have improved because     2    the rise of the commercial climbing business.In     3     1990s, experienced guides began leading groups of new climbers.Today more than 24 companies offer the service.Everest enthusiasts with little climbing experience can pay tens of thousands of dollars to have their hands     4     (hold) most of the way up.

Better weather forecasting has helped, too.Travelling from the base camp to the top of the mountain     5     (take) around four days, and success depends     6    (heavy) on weather conditions along the way.Spotting a suitable “window” of good climbing weather was difficult thirty years ago.With the     7     (develop) of technology, forecasting has vastly improved.

4 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.

The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.

First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”

Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.

The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

Throughout the centuries, pink has assumed a range of guises (表现形式). The way it is sensed by society has also changed over the years.

In the West, pink first became fashionable in the mid-1700s, when European aristocrats (贵族) were dressed in pink as a symbol of class. Madame de Pompadour loved the color so much that, in 1757, French porcelain manufacturer Sèvres named its new shade of pink “Rose Pompadour” after her.

Pink was not then considered a girls’ color — infants of both genders were dressed in white.     1     The color’s more recent association with femininity (女性气质) started around the mid-19th century, according to Valerie Steele, editor of the book Pink: The History of a Punk, Pretty, Powerful Color. She explained, “Men in the Western world increasingly wore dark colors, leaving brighter options to females     2    . ”

By the turn of the century, pink had entered the mainstream — and its status shifted in the process. The advent of industrialization and mass production led to comparatively cheap dyes (染料). Pink went from luxury to working class.

Its guises continued to change throughout the 1900s.     3     By the 1950s, pink had become more gender-coded than ever. The branding and marketing in post-war America that used it as a symbol of super-femininity, strengthened a “pink for girls, blue for boys” stereotype.

Pink did not regain its popularity until the 1960s, when public figures such as Jackie Kennedy and Marilyn Monroe adopted it as a mark of luxury. In more recent decades, pink has also been accepted as a color of protest and awareness for various communities. For example, it has become internationally equivalent to the fight against breast cancer, in the form of a pink ribbon.

“Pink is going through a generational shift,” Steele said. “    4     There’s a shared recognition that pink can be pretty and powerful and feminine. We’re redefining pink.”

A．Pink became an expression of delicacy.

B．The color was in fact, often considered more appropriate for little boys because it was seen as a paler (浅的) red, which had manly implications.

C．Pink was regarded as simple, because of its association with women, who have been traditionally looked down upon.

D．Society is increasingly moving away from the idea of it as a childish color.

E．French designer Paul Poiret created dresses in pale pinks, pushing the shade back into the field of high fashion.

F．Society decides what colors mean.

Can Whales And Dolphins Fight Cancer?

Whales and dolphins have been shown to be better at fighting cancer than we are, and now we may be closer to understanding why cetaceans (鲸目动物)do it. Cetaceans are generally the oldest living mammals, and some cetaceans have reached their 200th birthday. Their size means their bodies contain far more cells than the human body.     1    

“If you have more cells that means that one of those cells has an increased risk of becoming cancerous.” says Daniela Tejada-Martinez at the Austral University of Chile. “So, if you are big or live longer, you have thousands and millions of cells that could become harmful.”     2    

“There’s a joke that whales should be born with cancer and not even able to exist because they’re just too big,” says Vincent Lynch at the University at Buffalo, New York, he says there is a super trivial explanation for how whales can exist. “They just evolved better cancer protection mechanisms,” he says.     3    

Now, Tejada-Martinez and her colleagues have studied the evolution of 1077 tumor suppressor (肿瘤抑制)genes (TSGs). In all, they compared the evolution of the genes in 15 mammalian species, including seven cetacean species. Genes regulating DNA damage, tumor spread and the immune system were positively selected among the cetaceans.     4     “It’s not like we’re gonna be taking whale genes and putting them into humans and making humans cancer resistant,” says Lynch. “But if you can find the genes that play a role in tumor suppression in other animals, and if you can figure out what they’re doing, maybe you can make a drug that can be used to treat people.”

A．They also found cetaceans gained and lost TSGs at a rate 2.4 times higher than in other mammals.

B．If the whale gene was injected into the human body, could humans fight cancer?

C．Some people deny that cetaceans can increase TSGs faster than other mammals.

D．Why this happens remains a mystery.

E．In contrast, cetaceans have much lower cancer rates than most other mammals.

F．But we still need to learn more about why and how they did this.

The Paint Creek Recreation Trail is the flagship pathway of a planned trail network in the Ohio counties of Fayette, Ross and Highland. Nearly 35 miles of paved trail are currently open linking the communities of Washington Court House, Frankfort and Chillicothe.

The vast majority of the trail occupies a former railroad corridor acquired by the local nonprofit trails group in 1994. However, the trail does leave the original corridor where the right-of-way could not be acquired from its current owners. The diversions are usually short, with the longest stretch being a 2.5 mile stretch of highway cast of the Washington courthouse.

Because most of the trails through rural Ohio are dominated by seemingly endless fields, trail users are exposed to the sun for long periods of time. Fortunately, the path occasionally winds through a more wooded corridor near local waterways, such as Paint Creek and the Scioto River.

The Paint Creek Recreation Trail also passes through the downtown areas of the three towns along the way, offering many opportunities for rest and energy. Just before Chillicothe, trail users will want to stop at Hopewell Culture National Historical Park. The Hopewell Mound Group, a part of the park visible from the trail along Sulphur Lick Road, features earthworks and tombs built by the local people nearly 2,000 years ago.

The existing Paint Creek Recreation Trail will one day make a significant contribution to local leisure and transportation. There are plans nowadays to develop new trails along former railroad corridors from Washington courthouse northwest to the existing Xenia-Jamestown Connector, southwest to Wilmington and cast to Circleville in Pickaway County.

1. Which of the following is true about the trail?

A．Most of the trail is not well remodeled.

B．Most of the trail used to be a railway passage.

C．Most of the trail goes through the centers of 13 towns.

D．Most of the trail is close to the local railway lines.

2. What’s the prospect of this trail in the future according to the passage?

A．It will take on a new look.

B．It will be part of a national historic park.

C．It will be bought by a nonprofit company.

D．It will play an important role in leisure and transportation.

3. Where might this article come from?

A．An American website on travel.	B．An English scientific magazine.
C．A lecture by a professor   of geography.	D．A travelers' notebook.

8 . Ever wondered if dogs can learn new words? Yes, say researchers as they have found that talented dogs may have the ability to grasp new words after hearing them only four times.

While previous evidence seems to show that most dogs do not learn words, unless eventually very well trained, a few individuals have shown some extraordinary abilities, according to a study published in the journal Scientific Reports.

“We wanted to know under which conditions the gifted dogs may learn novel words,” said researcher xuekw Claudia Fugazza from the Eötvös Loránd University in Hungary. For the study, the team involved two gifted dogs, Whisky and Vicky Nina. The team exposed the dogs to the new words in two different conditions.

In the exclusion-based task, presented with seven known toys and one new toy, the dogs were able to select the new toy when presented with a new name. Researchers say this proves that dogs can choose by exclusion when faced with a new word, they selected the only toy which did not have a known name.

However, this was not the way they would learn the name of the toy. In fact, when they were presented with one more equally new name to test their ability to recognize the toy by its name, the dogs got totally confused and failed.

The other condition, the social one, where the dogs played with their owners who pronounced the name of the toy while playing with the dog, proved to be the successful way to learn the name of the toy, even after hearing it only 4 times. “The rapid learning that we observed seems to equal children’s ability to learn many new words at a fast rate around the age of 18 months,” Fugazza says. “But we do not know whether the learning mechanisms(机制) behind this learning are the same for humans and dogs. ”

To test whether most dogs would learn words this way, 20 other dogs were tested in the same condition, but none of them showed any evidence of learning the toy names, confirming that the ability to learn words rapidly in the absence of formal training is very rare and is only present in a few gifted dogs.

1. What was the purpose of the study published in Scientific Reports?

A．To better train dogs’ ability to learn new words.

B．To further confirm previous evidence about dogs.

C．To prove extraordinary memory abilities of gifted dogs.

D．To explore favorable conditions for gifted dogs’ new-word learning.

2. How did the dogs react when exposed to two new names in the first condition?

A．Slow to understand.

B．Quick to learn.

C．At a loss.

D．In a panic.

3. What was found about dogs’ new-word learning in the social condition?

A．Learning through playing applied to most dogs.

B．The social condition helped dogs learn new words.

C．Dogs’ new-word learning turned out to be less effective.

D．Dogs shared similar learning mechanisms with children.

4. Which of the following is the best title for the text?

A．Gifted Dogs Can Learn New Words Rapidly.

B．Dogs Identify Newly-named Toys by Exclusion.

C．Dogs Can Acquire Vocabulary through Tons of Training.

D．Gifted Dogs Have Similar Learning Abilities to Humans.

Will Experimentation on Animals End?

One of the most debatable issues in science is the use of animals in research. Scientists experiment on animals for different reasons, including basic research to explore how organisms function, investigating potential treatments for human disease, and safety and quality control testing of drugs, devices and other products.

    1    However, opponents believe it is cruel and meaningless, as observations in animals often do not translate directly to humans.

In 1959, William Russell and Rex Burch proposed their “3Rs” guidelines for making the use of animals in scientific research more humane: restrict the use of animals; refine experiments to minimize distress; and replace tests with alternative techniques.     2     Around 29 million animals per year are currently used in experiments in the U.S. and Europeans Union countries. This is less than half the total in the mid-1970s —— a significant drop.

    3    Improvements in imaging methods that offer a look inside the bodies of animals allow scientists to get more and better data from each experiment than before.

For example, researchers previously had to do experiments with multiple mice at different stages of cancer development, but now they can watch the disease develop in a single living animal using a dye. Similarly, as brain-imaging techniques become more advanced, some questions that were addressed with experiments in monkeys before may be better answered by looking into the human brain now. “    4    ” says Larry Carbone, a senior veterinarian(兽医) at the University of California in San Francisco.

A．Over the course of five decades their guidelines have become widely accepted worldwide.

B．The awareness of animal protection contributes to the decline of the number.

C．Human volunteers must be able to replace monkeys more and more in the next 10 to 20 years.

D．New experimental techniques help to push numbers down.

E．Its supporters point to the long list of medical advances made possible with the help of animal research.

F．The number of the animals used in research is still considerable.
