For over a century, native Asian honeybees have been steadily pushed aside by the European species, which were introduced to China by beekeepers because the female workers are more focused on their job and produce more honey, which is also sweeter.

However, the European species also carries a number of deadly diseases that can damage the natural habitat. Some researchers calculate that up to 80 per cent of China's native honeybee population has been lost since the first European bee farm in the country was established in the late 19th century.

The sweeping expansion of Asia's European honeybee population causes an ecological crisis. After more than 70 million years of evolution, native Asian honeybees could pollinate（对……授粉）a wide range of plant species in the region. However, many Asian bee species across the region are now close to extinction, and that's a cause for concern as the flowers of many Asian plants are not recognised by European honeybees, which will cause fundamental changes in the ecological balance.

A solution put forward by bee scientists was to draw a border between European and Asian honeybees. In some parts of China, bee farms are not allowed to use the European species, giving the native bees some breathing space.

After years of decline, the Eastern honeybees are gaining a foothold, especially in mountains and warm, tropical areas. It is because they can deal with the real hardship of life. The Western honeybees. on the contrary, rely very much on the protection and care of humans. Without caretakers, they have little chance to survive in Asia, where hornets（大黄蜂）alone could wipe them out.

The decline of Asian honeybees was alarming because of their important role in the food chain. Fewer bees mean fewer plants, fewer plants less food and less food fewer humans. We must take positive, sustainable steps towards protecting China's Asian honeybees.

1.What made China's native honeybees endangered？

A.Overdevelopment of the land.

B.Introduction of European bees.

C.Pollution from cars and factories.

D.Lack of a variety of plant species.

2.What can be inferred about many Asian plants from the third paragraph？

A.They will not flower.

B.They might grow slowly.

C.They might not be pollinated.

D.They will harm the environment.

3.What is basically typical of China's honeybees？

A.Sociable.

B.Aggressive.

C.Productive.

D.Adaptable.

4.What is the author's purpose in writing this passage？

A.To analyse influence of European bees.

B.To urge protection of native Asian bees.

C.To suggest ways of limiting European bees.

D.To introduce comeback of native Asian bees.

Believe it or not, cell phones have been around for over a quarter of a century.The first commercial cell phone system was developed by the Japanese in 1979. But cell phones have changed a lot since that time. The early cell phones appeared big and heavy but they have developed into small and light palm­sized models. There have been huge developments in their functions，too. We have had call forwarding, text messaging, answering services and hands­free use for years, but now the manufacturers equip countless new facilities, such as instant access to the Internet and receiving and Sending photos.

Cell phones have become very common in our lives；recent statistics suggest as many as one in three people on the planet now has a cell phone, and most of them say they couldn't live without one. Cell phones are used in every area of our lives and have become a necessary tool, used for essential arrangements, social contact and business. They have made it easier to call for help on the highway. They have made it possible to keep in touch with people “on the move” when people are traveling.

Cell phones have made communication easier and have reduced the need for family arguments. We can use cell phones to let our family know we'll be late or if there's a change of plan or an emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late, and they can now contact their children at any time.

This does not mean that cell phones are all good news. They have brought with them a number of new headaches for their owners: it costs a lot to replace stolen phones, something that is becoming a frequent occurrence, and have you ever seen such huge phone bills? More serious, however, is the potential health problem they bring: there are fears that radiation from the phones may cause brain tumor(肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones that they simply can't live without.

The Asian elephant has been respected for centuries and is still used today for ceremonies and religious purposes. It is respected, not only because it plays a role in Asian culture and religion, but also because it is a key biological species in the tropical forests of Asia.

The Asian elephant is the largest land mammal in Asian. It is smaller than the African elephant, with relatively smaller ears. Asian elephants have a single “finger” on the upper lip of the long trunk, while African elephants have a second on the lower tip. A number of adult male Asian elephants have no tooth, and the percentage of males carrying ivory(象牙）is different from only about 5% in Sri Lanka to 90% in south India. Asian elephants keep their ears in constant motion in order to free the heat they produce. The species is reported to have well-developed hearing, vision, and smell , and they are also fine swimmers.

Asian elephants prefer to convey something to form groups surrounding 6 to 7 related females that are led by the oldest female. Like African elephants, these groups occasionally join others to form herds, although these associations are relatively temporary.

More than two thirds of the day may be spent feeding on grasses, but large amounts of tree bark, roots, leaves and small stems are also eaten. Crops such as bananas, rice and sugar plants are favored foods. Besides, they need to drink at least twice a day so the source of water is quite important.

The Asian elephant used to live from modern Irap and Syria to the Yellow River in China at first, but it is now found only from India to Vietnam, with a tiny population in the extreme southwest of China’s Yunnan Province. More than 100,000 Asian elephants may have existed at the start of the 20th century. The population is estimated to have fallen by at least 50% over the last 60-75 years.

1.What can we learn from Paragraph2?

A.The Asian male elephant is the largest animal in the world.

B.The population of Asian male elephants with ivory varies by district.

C.The Asian elephant has two “fingers” on the lips of the long trunk.

D.Asian elephants continuously move their ears to warm themselves.

2.The Asian elephants are most likely to fed themselves______.

A. in a very large forest

B. in the field with leaves and stems

C. close to a river with grasses and leaves

D. on the hillsides with grasses and trees

3.What makes the author worried in the last paragraph?

A. That there are fewer and fewer Asian elephants.

B. That Asian elephants originally ranged more widely.

C. That Asian elephants may suffer some diseases.

D. That there was too much killing in the last century.

4.The passage introduces Asian elephants mainly in the aspects of ______.

a.the diet habit

b. the social structure

c. the life circle

d. the physical description

e. the skin color

f. the population and distribution

g. the cultural status

请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意：每个空格只填一个单词。

By the logic（逻辑）of geography, the continent of Australia should have been populated with Asians. Instead, by an accident of history, Australia has been mainly populated with Westerners.

Sadly, no major Australian newspaper or expert commented. This made me aware that Australians are reluctant to face Australia's painful new geopolitical realities.

Against this background, the release of the Asian Century White Paper is timely. It should provide a sharp wake-up call to the Australian population that Australia's destiny（命运）is now firmly tied to Asia. Julia Gillard is right in saying, "The transformation of the Asian region into the economic powerhouse of the world is not only unstoppable, it is gathering pace."

One truly impressive part of the paper is the data it provides on Asia's rise. It notes, for example, that "in the past 20 years, China and India have almost tripled（增三倍）their share of the global economy and increased their economic size almost six times over. By 2025, the region as a whole will account for almost half the world's output."

In this Asian century, as Western power gets weak steadily, Australia will be left "beached" alone as the only Western country （together with New Zealand） in Asia. Twenty-two million Australians will have to learn to deal with 3.5 billion Asians with great care and sensitivity.

Ignorance（无知）about Asia could prove to be fatal（致命的）for Australia's long-term future. This is why the report is right in focusing on Australian misunderstanding of Asia.

Sadly, this kind of terrible ignorance may be a result of Australian education. The report says, “Only a small proportion of Year 12 students study anything about Asia in the subjects of history, literature, geography, economics, politics and the arts under existing state-based curriculums." Worse, only 5 per cent of each Australian groups study any kind of Asian language.

Learning Asian languages would open windows to Asian cultural and political sensitivities. The time for Australians to think deeply about their Asian destiny has arrived. The sooner Australia adjusts to its new Asian destiny, the less painful the adjustment will prove to be.

Over the past century, all kinds of unfairness and discrimination(歧视) have been made illegal. But one popular form continues to exist, that is alphabetism (字母排序法). This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames (姓氏) begin with a letter in the lower half of the alphabet.

It has long been known that the cars of a taxi firm called AAAA have a big advantage over Zodiac cars when customers look through their phone directories. Less well known is the advantage that Adam Abbot has in life over Zoe Zysman. English names are fairly spread between the halves of the alphabet. Yet a quite large number of top people have surnames beginning with letters between A and K.

Thus the American presidents and vice-presidents have surnames starting with B and C separately and 26 of those before George Bush took office (including his father) had surnames in the first half of the alphabet against just 16 in the second half. Even more striking, six of the seven heads of government of the G7 rich countries are alphabetically advantaged (Berlusconi, Blair, Bush, Chirac, Chretien and Koizumi ). The world’s three top central bankers (Greenspan, Duisenberg and Hayami) are all close to the top of the alphabet, even if one of them really uses Japanese characters. The same case are the world’s five richest men (Gates, Buffet and so on).

Can this merely happen by chance? At the start of the first year in primary school, teachers seat pupils alphabetically from the front, to make it easier to remember their names. So shortsighted Zysman gets stuck in the back row, and is seldom asked the improving questions by those teachers. At that time the alphabetically disadvantaged may think they have had a lucky escape. Yet the result may be worse qualifications, because they get less attention, as well as less confidence in speaking publicly.

The unfairness continues. At university graduation parties, the ABCs proudly get their awards first. However, by the time they reach the Zysmans most people are a little tired. Lists of job interviews and conference speakers and attendees all tend to be drawn up alphabetically, and their readers lose interest as they plough through them.

1.What does the author intend to show with AAAA cars and Zodiac cars?

A. An example of competition of two kinds of cars.  B. Some advantages of AAAA cars in the taxi firm.

C. An example of unfairness caused by alphabetism.  D. Some disadvantages of Zodiac cars in the taxi firm.

2.What can we infer from the first three paragraphs?

A. The alphabet is to blame for the failure of Zoe Zysman.

B. In both East and West, names are important to success.

C. Customers often pay a lot of attention to companies’ names.

D. The discrimination in alphabetism can be found in many areas.

3.The fourth paragraph suggests that         .

A. alphabetically disadvantaged students often escape from class

B. teachers should pay equal attention to all their students

C. questions are often put to the more intelligent students

D. students should be seated according to their eyesight

4.Which of the following is true according to the passage?

A. VIPs in the western world gain a great deal from alphabetism.

B. People with surnames beginning with N to Z are often ill – treated.

C. Putting things alphabetically may lead to unintentional unfairness.

D. The movement to get rid of alphabetism still has a long way to go.

Plastic is piling up in ecosystems all over the world. Although its harmful impacts on both species and ecosystems have been documented, a few animals—like bowerbirds and hermit crabs—are doing what they can to recycle it. And according to a recent study, wild bees in Canada have joined the effort, which is a rare observation of behavioral flexibility in species especially insects, in increasingly plastic-rich environments.

The researchers found two species of leafcutter bees putting plastic into their nests. One of the bees they studied, the alfalfa leafcutter bee, normally bites off pieces of leaves and flowers while the second bee gathers sticky substances from trees. Leafcutter bees don't build big nests or store honey like honeybees, choosing instead small nests in underground holes, tree holes or cracks （裂缝）in buildings. But the researchers found that three of eight brood cells（育雏巢室）contained pieces of plastic bags, replacing 23 percent of the cut leaves in each cell on average.

While they don't make honey, alfalfa leafcutter bees still make money for the U. S. and Canadian farmers by pollinating（给......传授花粉）crops including alfalfa , carrots and melons. The European insects were introduced to North America in the 1930s for that purpose, and they've since become wild, joining the continent's many native species of leafcutter bees.

In a separate study conducted in Argentina between 2017 and 2018, researchers found a bee nest made entirely of plastic, which consisted of three separate cells. It's the first known example of such construction worldwide. Compared to the other nests the researchers examined, which were made of natural materials, this one had a pretty lower success rate of the bees' survival. One of the cells had a dead baby bee , another seemed to have housed an adult that had left the nest, and the third was unfinished.

1.What does the animals' use of plastic show according to the study?

A.How widely plastic is used.

B.How strange the behavior of wildlife is.

C.How some wildlife is adapting to plastic.

D.How plastic pollution has harmed them.

2.What do leaves mean to alfalfa leafcutter bees?

A.Food. B.Shelter.

C.A plastic substitute. D.Traditional nest materials.

3.Which is one characteristic of leafcutter bees?

A.They have great economic value.

B.They store honey like honeybees.

C.They prefer to live in tree holes.

D.They have evolved into a new species.

4.What was the nest made entirely of plastic like?

A.It might be warmer. B.It might be unhealthy.

C.It might be easy to finish. D.It might be recyclable.

Is there a way to turn back the aging process in people? For centuries, people have been looking for a “fountain of youth.” The idea is that if you find a magical fountain, and drink its water, you will not age.

Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on.

Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural stem cells (干细胞) also influence how fast aging takes place.

Dongsheng Cai, a professor at the Albert Einstein College of Medicine, was the leading researcher in a study on aging in mice. He and his team reported their findings.

“Aging speed can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells.” He adds that when the hypothalamus starts aging, so does the body. So when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost, it eventually leads to aging.

Using this information, the researchers began trying to activate the hypothalamus in laboratory mice. They did this by injecting the animals with stem cells.

The researchers say the results show that the treatment slowed aging in the animals. “When we injected the hypothalamus stem cells to the middle-aged mice, the mice aged slowly and they can also live longer.”

But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings.

“If we can translate what we have seen in animals to humans, I think humans can function better during later ages.” Cai and his team say their studies may have other benefits. They say the findings could lead to new ways to help doctors identify and treat any number of age-related health issues.

1.Why does the author mention the “fountain of youth” in the first paragraph?

A. To explain what the “fountain of youth” is.

B. To introduce the hypothalamus.

C. To show how to find the “fountain of youth”.

D. To help people find the “fountain of youth”.

2.What does the underlined word “it” in Paragraph 2 refer to?

A. The brain.　　 B. The aging process.

C. Hypothalamus.　　 D. The stem cell

3.What do we know about the study done by Cai?

A. They have found a way to turn back the aging process.

B. The brain controls growth, reproduction and the way we process food.

C. The decrease of hypothalamus stem cells can lead to aging.

D. The finding has been applied to human beings.

4.Which of the following can be the best title of the passage?

A. The Fountain of Youth

B. A New Discovery about Aging

C. The Ways of Slowing Down Aging

D. Hypothalamus—the Fountain of Youth

Vampires (吸血鬼), creatures of myth, have been around in one form or another for centuries. Terrifying but also attractive, they are as popular in the early 21 st century as ever, as the current popularity of Twilight series, and its hero Edward Cullen, show.

Vampires first appeared in fiction in the 1700s. in 1895 Irish novelist Bram Stoker published Dracula, introducing the world’s most famous vampire.

But just what is it about these drinkers of human blood that continues to fascinate us? Speaking to Eric Lewis of the Times and Transcript website, academic Deborah Wells said that vampires are “culturally adaptive”. “We create very different vampires to fit different times. Edward Cullen is not the same as Count Dracula,” she said.

Different as they are, Wells believes vampires are “the perfect containers into which we can pour our current cultural anxieties”, Bram Stoker’s Dracula is powerful, yet old and physically ugly. Stoker’s book dealt with fear of the fall of the British Empire, real fears in the day in which it was written.

According to the website Bookrags, today’s vampires have all our cultural desires, money, power and sexual attraction. Represented by Cullen, they are noble, handsome young men whom women find irresistible. What’s more, vampires challenge traditional ideas about death, science and parental authority. This may be why teenagers are drawn to vampire tales.

“In many ways, the vampire story shows up teenage concerns,” said wells. “The emotional intensity (强度) of the relationship with the vampire matches the intensity of how it feels to have your first real love affairs. Your first real love, it really feels like life and death.”

55．The best title for this passage should be_______.

A．Vampires may continue to drink our blood

B．Vampires have been around us for long

D．We still like the story about vampires

56．What is the image of the vampire in Bram Stoker’s book?

A．Anxious but perfect.

B．Powerful, old and ugly.

C．Terrifying but also attractive.

D．Afraid of the fall of the British Empire.

57．According to the website Bookrages, today’s vampires_______.

A．desire money, power and sexual attraction

B．may not think highly of parental authority

C．dare to give up traditional ideas

D．are likely to be resisted by women

58．Which of the following statements is true according to Wells?

A．People need different vampires in different times.

B．Our current cultural anxieties are hidden in vampires.

C．The vampire story reflects the conches of the teenagers.

D．The relationship with the vampire equals your first real love.
