Vast deserts, magic carpets, and the legend of Aladdin’s lamp. For most Chinese people, Saudi Arabia is a faraway land that exists only in bedtime stories.

However, connections between the two countries date back to ancient times. The economic and cultural ties between the Tang Dynasty (AD 618-907) and the Arabian empire reached their height in the 9th century. Paper-making workshops did thrive in what is now Saudi Arabia while Arabian knowledge of math, astronomy and spread to the Middle Kingdom.

These exchanges, recorded by Arabian merchants sailing along the ancient Maritime Silk Road, became materials for folk stories, such as the One thousand and One Nights stories.

Fast forward a millennium (千年), the relationship between a modern Saudi Arabia and a progressive China has entered a new era, thanks to the Belt and Road Initiative proposed by Chinese President Xi Jinping in 2013.

“Saudi Arabia is one of the first countries that responded positively to the Belt and Road Initiative,” Saudi Ambassador to China Gurki Mohanmed told Xinhua.

“In terms of strategic location, Saudi Arabia serves as the central place connecting Asia, Africa and Europe, making it an important part of the initiative,” he added.

In fact, since they built diplomatic ties in 1990, the two countries have seen a sound development of partnerships. In 2015, China became Saudi Arabia’s largest trade partner while Saudi Arabia has been China’s biggest crude oil supplier next to Russia and largest trade partner in West Asia and Africa for years.

Xu Mengmeng is now completing his graduation project on marine science at the King Abdullah University of Science and Technology in Saudi Arabia. On weekdays, he works on his research project on sharks. When free, he tours the city to experience the local culture.

Now China has become a favorite choice of Saudi Arabian students expecting to study overseas. Momudouh from Saudi Arabia came to Xi’an to study marketing in 2010. He told Xi’an Daily that he was attracted by the fast trade opportunities between the two counties. He desired to bring back the so-called new four inventions back to his home country—high-speed rail, Alipay, bicycle sharing and online shopping.

1.What does the underlined word “thrive” in Paragraph 2 probably mean?

A. Fail.

B. Boom.

C. Fade.

D. Close.

2.What can we learn from the economic and cultural exchanges between the two countries?

When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.

Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat.”

Researchers have agreed that today’s dog is the result of the domestication(驯化) of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendents(后代) of which now live with people in Alaska, Canada, and the Lower 48.

Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永冻层) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.

Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(标本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.

Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep,” Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource.”

1. The underlined word “remains” is closed in meaning to ______.

A. leftover food     B. animal waste

C. dead bodies    D. living environment

2. According to the study described in Paragraph 4, we can learn that ______.

A. ancient dogs entered North America between 1450 and 1675 AD

B. the 11 bones of ancient dogs are not from native American dogs

C. the bones discovered by the gold miners were from North American wolves

D. the bones studied were not from dogs brought into North America by Europeans

3. What can we know from the passage?

A. Native Americans domesticated local wolves into dogs.

B. Scientists discovered some ancient dog remains in 1920s.

C. Latin America’s dogs are different from North America’s in genes.

D. Ancient dogs entered North America across the Bering Land Bridge.

4. The first humans into the New World brought dogs along with them because ______.

A. dogs fed on mice                    B. dogs were easy to keep

C. dogs helped protect their resources      D. dogs could provide excellent service

5.What does the passage mainly talk about ______.

A. the origin of the North American dogs

B. the DNA study of ancient dogs in America

C. the reasons why early people entered America

D. the difference between Asian and American dogs

Antarctica is known for being a vast land of ice and snow, a place too cold for most life. Despite this, the continent is slowly starting to turn warm. According to the Guardian, the Antarctic has registered a new high temperature for the first time on record, prompting fears of climate instability in the world's iciest place.

On Feb 9, Brazilian researchers at Seymour Island reported a temperature of 20.75℃ on the icy continent of Antarctica. It was almost a full degree higher than the previous re- cord of 19. 8℃ , taken on Signy Island in January 1982.

This record — breaking reading was taken at a monitoring station in the northern part of Antarctica. According to Brazilian soil scientist Carlos Schaefer, the temperature was documented during a 20-year-long research project. The focus of this project is to study the effect that climate change has on the permafrost(永久冻土) within the region. Permafrost is soil that stays frozen for at least two years. Although this is a first record high for Antarctica, Schaefer stressed that “We can't use this to anticipate climatic changes in the future. It's simply a signal that something different is happening in that area.”

But in fact, the last high temperature reading was in the 19℃range. These higher temperatures can cause ice and glaciers in Antarctic regions to melt. The Antarctic peninsula—the long finger of land that stretches towards Argentina—is most dramatically affected. Scientists saw glaciers that have retreated by more than 100 meters in Discovery Bay where the snow melted in little more than a week, leaving dark exposed rock. This melted ice leads to a rise in sea levels that can threaten the safety of coastal areas. It's believed to be behind an alarming decline of more than 50 percent in chinstrap penguin(帽带企鹅) colonies, which are dependent on sea ice.

Like American writer Ernest Hemingway once said, “The Earth is a fine place and worth fighting for.” We should do everything we can to help save our planet. Otherwise, it may become too hot for us to fix.

1.What did Brazilian researchers report on Feb 9?

A.Seymour Island is the warmest region in the Antarctic.

B.Antarctica hit a record high temperature of 20. 75℃.

C.The average temperature of Antarctica ranges from 19. 8°C to 20. 75℃.

D.Antarctica's new record temperature is a full degree higher than the previous decade.

2.What's the main purpose of the 20-year-long research project?

A.To predict possible climatic change in the future.

B.To monitor Antarctica's contributions to world climate change.

C.To explain why the permafrost may cause glaciers to melt.

D.To examine how the permafrost is influenced by climate change.

3.What does the underlined word “retreated” probably mean?

A.moved backward. B.increased in size.

C.covered a certain area. D.stretched in an opposite direction.

4.According to the text, the melted glacier may lead to　　　　　 .

A.the pollution of ocean water B.the release of various viruses

C.threats to penguin habitats D.disappearances of coastal cities

It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals. An elephant can’t swim across the Pacific, after all. But it turns out that plenty of plants and animals have unintentionally floated across oceans from one continent to another. Now comes evidence that tiny, trapdoor spiders (蜘蛛) made such a journey millions of years ago.

Moggridgea rainbowi spiders can be found on Kangaroo Island, which sits off the south coast of Australia. These spiders build a silk-lined hole in the ground, notes Sophie Harrison, a biologist in Australia. The hole and trapdoor provide these spiders with shelter and protection. It also provides them an out-of-sight spot from which to wait for approaching creatures.

There is evidence, though, that the ancestors of them might have traveled millions of meters to get to Australia from Africa. That isn’t as unlikely as it might at first seem. Australia used to be connected to other continents, long ago, as part of a supercontinent called Gondwana. And humans have been known to transport species all over the planet. But there’s a third option. The spiders might have rafted (乘筏) long distances across the sea.

To figure out which story was most likely true, Harrison and her colleagues looked at the spider’s genes. They looked at the genes in seven Moggridgea rainbowi spiders from Kangaroo, and five species of Moggridgea spiders from South Africa. The Australian and African spiders split off from a common ancestor some 2 million to 16 million years ago, the genes showed.

If a large swatch of land washes into the sea, filled with arachnids (蛛形纲动物), the spiders may be able to hide themselves throughout the journey. Plus, they can “hold their breath” and survive on stored oxygen during periods of temporary flooding, the researchers note.

1.What is the common belief about land animals according to the text?

A.They are sensitive to natural disasters.

B.They are unlikely to move across oceans.

C.They can’t make a long ocean voyage.

D.They float across oceans accidentally.

2.What does the underlined word “them” in Paragraph 3 refer to?

A.Biologists. B.Australians.

C.The spiders. D.The creatures.

3.How did the researchers conclude Australian and African spiders are from a common ancestor?

A.By comparing their genes.

B.By observing their living habits.

C.By making changes to their genes.

D.By studying their physical characteristics.

4.What could be the best title for the text?

A.These Spiders Traveled Globally to Hide Themselves

B.These Spiders Became More Adaptive When Traveling

C.These Spiders Crossed an Ocean to Australia for Survival

D.These Spiders Crossed an Ocean to Become Australians naturally

高三英语阅读理解中等难度题查看答案及解析

There is an unforgettable beauty to the Karoo, a vast semi-desert, that seems empty save for the stars overhead and sheep eating grass below. Economic opportunities here are few.

But the Karoo’s clear skies also draw some of the world's best scientists. A radio telescope project called the Square Kilometre Array (SKA) is under construction, with the latest group of 64 giant antennae（天线）due to be completed late next year. When finished, it will be the biggest radio telescope in the world and should allow scientists to peer into the origins of the universe.

Still, some sheep farmers are complaining. Because of the sensitivity of the telescope, the surrounding area must be kept free from radio interference（干扰）caused by everything from mobile phones to microwave ovens and some car engines. The SKA is buying up more farms than originally expected to ensure radio silence over an area of some 130,000 hectares. There will be no mobile phone signals allowed, except in the few towns in the area. Save the Karoo, an advocacy group, isn’t convinced by the bright future of groundbreaking astronomical discoveries. Its members fear the restrictions will make the Karoo “a cut-off and backward region”, and warn that people serving farms near the SKA site could face financial ruin. “I don't care about a black hole siting somewhere out in space,” says Eric Torr, an organiser with the group. “It does not put food on the table.”

Sky-high expectations in this down-at-heel area are also a problem. An SKA official complains that the locals expect the telescope to solve all their problems. Some jobs have been created, but few locals have the skills to find out the secrets of distant galaxies. Until recently the high school in Carnarvon, a nearby town, didn’t even have a maths and science teacher. The SKA organisation hired one, and is also offering scholarship to college students. Perhaps if the next generation's horizons are raised, they will be able to take advantage of the radio telescopes in their own backyard.

1.The project SKA is aimed at ______.

A.creating jobs for locals B.exploring the universe

C.protecting the sheep D.saving the Karoo

2.What most disturbs the locals’ life?

A.The shrinking of their farmlands. B.Restrictions of radio signals.

C.The construction of the project. D.Noises of car engines.

3.What can be inferred from Eric’s words?

A.Food should be put on the table. B.Eric faces financial difficulty.

C.The black hole is nowhere to be found. D.The project makes no sense to Eric.

4.What can be a suitable title for the text?

A.Telescope in the Backyard B.Expectations of the Locals

C.Biggest Radio Telescope D.Great Astronomical Discovery

Life， my friend Bando once said， is meeting problems and solving them whether you are an amoeba or a space traveler． I have a problem． I have to provide my younger sister Alice and myself with meat． Fish， nuts， and vegetables， are good and necessary， but they don't provide enough fuel for the hard physical work we do． Although we have venison（鹿肉） now， I can't always count on getting it． So far this year， our venison has been only road kill from in front of Mrs． Strawberry's farm．

I decide to take the longest way home， down the flood plain of the West Branch of Delaware to Spilkill， my own name for a fast stream， that cascades down the south face of the mountain range I'm on． I need time to think． Perhaps Alice and I should be like the early Eskimos． We should walk， camp and hunt， and when the seasons change， walk on to new food sources． But I love my tree and my mountaintop．

Another solution would be to become farmers， like the people of the Iroquois Confederacy who once lived here． They settled in villages and planted corn and squash（南瓜）， bush beans and berries． We already grow groundnuts in the damp soil and squash in the poor land． But the Iroquois also hunted game． I can't do that anymore

I'm back where I started from．

Slowly climb the Spillkill． As I hop from rock to rock beneath shady basswoods and hemlocks， I hear the cry of the red﹣tailed hawk who nests on the mountain crest． I am reminded of Frightful and my heart aches． I can almost hear her call my name， Cree， cree， car﹣ree．

Maybe l can get her back if l beg the man who is in charge of the peregrines（游隼） university． "But it's the law，" he would say． L could write to the president of the United states and ask him to make an exception of Alice and me． That won't work． The president swore to upload the constitution（宪法） and laws of the United States when he took office．

I climbed on． I must stop thinking about the impossible and solve the problem of what to do now． I must find a new way to provide for us． Frightful is going to be in good hands at the university and she will have young．

I smile at the thought of little Frightfuls and lift my reluctant feet．

When I am fat above the river，1take of my clothes and moccasins（鹿皮鞋） and bathe in a deep， clear pool until I am refreshed and thinking more clearly． Climbing up the bank， I dress and sit down． I breath deeply of the mountain air and try to solve my problem more realistically．
