1 . Temperatures around the North Pole have greatly increased in the last 50 years — changing a long-term natural cooling trend. Now the Arctic is warmer than at any time during the last 2000 years, according to a major new study.

The study, based on an analysis of tree rings and other things, provides compelling evidence that greenhouse gases released since the start of the industrial revolution are causing global warming.

An author, Darrel Kaufman said, “Scientists have known for a while that the current period of warming was coming after a long-term cooling trend. But our reconstruction quantifies the cooling with greater certainty than before.”

The research — published in the journal Science — comes from a team of British and American scientists who followed summer Arctic temperatures to the time of the Romans by studying natural signals in the landscape. Their reconstruction found that the Arctic got cooler in the summer months between 1 AD and 1900, thanks to a natural “wobble” (摇摆) in the Earth’s orbit around the Sun.

The wobble slowly increased the distance between the Earth and the Sun during the Arctic summer, reducing the summer temperatures by around 0.2 degree every thousand years and causing the “Little Ice Age” that led to freezing winters in the 17th, 18th and 19th centuries.

But during the 20th century, temperatures began to rise greatly — though the amount of sunlight reaching the Arctic during the summer was continuing to fall. The decade between 1999 to 2008 was the warmest in the last 2000 years, the research found. The research has shown that Arctic temperatures rose three times faster during the 20th century than the rest of the Northern Hemisphere.

Some researchers have predicted that the Arctic could be free from sea ice in the winter within the next few decades if the temperatures continue to rise.

4 . In July, my friend and I took a camping trip. We travelled for four weeks and visited the United States and part of Canada. We decided to camp because it took less money than living in hotels.

We planned very carefully. First, the car we were going to drive was very small, so we decided to take only one small bag each and as few camping things as possible. We took some medicine with us, to prevent (预防) insects and also food for picnics. Second, there was a lot to see in the United States and Canada, so we had to decide on the direction we wanted to drive on a big map.

All of this planning took a long time. The date we started was July 2.We saw and did many things on our camping tour. We climbed in the mountains, visited famous caves, and swam in cool mountain rivers. We visited many cities and talked to many people. We went to a hotel room when it rained at night. We had an exciting trip.

1. The two friends went camping ______ .

A．for four days	B．with all their friends
C．so they can save money	D．because it was warm in July

2. Which of the following statements was possibly true?

C．They were quite rich.	D．They went by car.

3. We learn from the second paragraph that ______ .

A．they must have been ill	B．they must have brought a lot in the car
C．they must have studied the map carefully	D．they must have been hurt by insects

4. It is quite clear that ______ .

A．the two friends didn’t take any food with them

B．they are sure to take some medicine with them on the trip

C．the two friends will take turns to drive

D．there will be no insects at all

5 . Cold winter coming

Big snowstorms and cold air swept across northern China in the first week of November. Many people trembled in the freezing cold. At the same time, a global meeting on climate change—COP 26—was held in Glasgow, Scotland. There, leaders from around the world tried to deal with global warming.

Why are we experiencing such a cold winter on a warming planet? The cold winter and global warming, two seemingly opposite facts, are not contradictory. Global warming does not happen evenly(均衡地) on Earth, and it causes more extreme heat and cold.

Because of the warming climate, China has seen a growing average temperature in winter. It has increased by 0.41 C every ten years since 1961. But in some cases, the country has also seen freezing cold—for example, the icy weather in early 2008.

Global warming has changed Earth’s air circulation(循环), affecting the local weather through sea-air or land-air interaction. For example, in October, La Nina affected China. It is a weather pattern caused by strong winds above the Pacific Ocean. It brought more cold air to China.

Another reason for the cold weather is the warming Arctic. It is warming almost three times as fast as any other place on Earth. The polar vortex(极地涡旋)—a rotating pool of cold air—becomes unstable as the temperature increases there. So, lots of cold Arctic air then goes southward.

Will this winter be much colder? The official forecast said a cold winter is likely. Northern China will probably see more snow than average, and southern China less rainfall than average.

7 . Parrots live extremely long partly due to their relatively large brains, an international team of researchers has discovered. Simeon Smeele, a doctoral student at the Max Planck Institute of Animal Behavior, led the study, the results of which were published in March in the Proceedings of the Royal Society.

When it comes to lifespan (寿命), birds truly stand out. Lifespan tends to increase with an animal’s body size, roughly speaking. Thus, the bigger the animal, the longer they live. But a bird tends to live much longer than a comparably-sized mammal. One theory is that birds’ ability to fly means they are less at risk from the animals that kill them, which reduces their risk of being eaten, decreases stress, and frees up bodily resources for growth.

And among birds, parrots are the aging champions. The confirmed longest-living bird was Cookie, a Major Mitchell’s cockatoo (a species of parrot), who lived at the Brookfield Zoo in Illinois for all but one of his 83 years. Though cockatoos often weigh around a pound, they usually live for four decades. Most of the other 398 parrot species also live longer than other birds of similar size.

What sets parrots apart? In the new research, Smeele and his colleagues gathered data on over 130,000 individual parrots held in more than 1,000 zoos, representing 217 species. Through this data, they created reliable estimates of the average lifespan for each species. They next searched for a link between each species’ lifespan and its relative brain size and found a clear, positive correspondence. Parrot species with larger brains relative to their body size lived longer than species with smaller brains.

“This supports the idea that in general larger brains make species more flexible. For flexibility allows them to live longer.” Smeele said in a statement. “For example, if they run out of their favorite food, they could learn to find something new and thus survive.” He added, “All parrots have relatively large brain sizes compared to most other birds.”

Researchers have previously shown that, when trained, some parrots can recognize and understand objects, colors, and shapes, and even speak with an impressive vocabulary. They can even match five-year-old humans on basic tests of intelligence.

1. What may cause birds’ long life?

A．Their big body size.	B．Their ability to fly.
C．Their less adventurous nature.	D．Their slow-paced lifestyle.

2. What do we know about parrots according to the text?

A．They outlive other similar-sized birds.

B．They live longer in the zoo than in the wild.

C．They have an average lifespan of four decades.

D．They live in relatively less competitive environments.

3. What does the underlined word “correspondence” in Paragraph 4 probably mean?

A．Goal.

B．Evidence.

C．Difference.

D．Connection.

4. What does the author want to stress with the example in Paragraph 5?

A．Parrots find it hard to survive nowadays.

B．Bigger brains give parrots more adaptability.

C．Parrots like to discover new things by nature.

D．Bigger brains aid parrots with their social ability.

5. What would be the best title for the text?

A．Why do parrots live so long?	B．Why are parrots so intelligent?
C．What do parrots do for a living?	D．What are the longest living animals?

8 . According to the National Audubon Society, about 60 percent of all North American bird species have experienced northward shift during migration over the past four decades. This is symbolic of habitat loses from human development, as well as climate change. Without taking action to protect migratory bird’s habitats, many of these species will eventually die out, which in turn can destroy the ecosystems that depend on the bird species. While these numbers are based in North American, bird extinction is a worldwide problem.

World Migratory Bird Day was established in 2006 as a holiday to help educate the public and raise awareness about the growing problems that are affecting the habitats of bird species around the world. It has since become a holiday recognized by the United Nations, and it helps to organize events in numerous countries. World Migratory Bird Day was established at the height of the age in which humans were starting to understand the influence of climate change.

Since World Migratory Bird Day is held over the second weekend of May, the dates can differ. In 2014, the holiday started on Saturday, May 10^th. In 2015, the starting date was May 9^th. Celebrating the holiday over an entire weekend gives families and bird enthusiasts alike a chance to get outdoors and learn more about migratory birds.

Education is at the center of World Migratory Bird Day celebration. The number of programs and festivals continue to grow each year, the content differing by area. World Migratory Bird Day provides people with the opportunity to learn about their favourite birds, and there are often bird watching tours planned for that weekend.

While World Migratory Bird Day can be a fun way to learn about birds and their habitats, the weekend holiday is also focused on some serious notes surrounding conservation. At events and festivals, the public can learn exactly how their native birds’ habitats are being destroyed, and more importantly, people can learn how to stop the destruction.

1. What does the first paragraph mainly talk about?

A．The destruction of ecosystems.

B．The seriousness of bird extinction.

C．The reason to protect migratory birds.

D．Causes of migratory birds’ habitat losses.

2. Which of the following does the author agree with?

A．Climate change is the main cause of bird extinction.

B．Migratory birds’ habitat losses may endanger our ecosystem.

C．Bird extinction is a matter of course of historical development.

D．There is no doubt that bird migration can speed up global warming.

3. What does the author think of the establishment of World Migratory Bird Day?

A．Worthy but impractical.

B．Timely and educational.

C．Simple but beneficial.

D．Meaningless and wasteful.

4. What do you know about World Migratory Bird Day?

A．It is suitable for people of certain ages.

B．The dates of celebrations are changeable.

C．It is held by bird enthusiasts and experts.

D．It aims to provide chances for families to unite.

5. What can be inferred from the last two paragraph?

A．People can watch the whole process of bird migration.

B．People have the chance to have a direct connection with birds.

C．Learning to recognize birds is the key purpose of celebration.

D．The holiday lets people appreciate and encourage protection of birds.

10 . There will be a miracle when you believe. Against all odds, a beloved border collie (博德牧羊犬) has amazingly been _______ with her owners who spent 57 days searching for her.

Carole King and her husband Verne had traveled to Kalispell from their home in Spokane, Washington so they could enjoy a relaxing 4-day _______ in the mountain wilderness.

_______ , their vacation turned into a _______ search mission after they found that their 7-year-old border collie named Katie had _______ from their room.

The Kings immediately _______ their return trip home so they could stay in Kalispell and search for Katie. For several weeks, they _______ hundreds of advertising leaflets throughout the community; they published her _______ on social media channels and Facebook groups; concerned local citizens helped them _______the countryside — but they still couldn’t find Katie.

At one point, Carole traveled back home so she could go back to her job as a mail carrier; but when they _______ her request to take additional time off to keep searching, she _______.

_______ returning to Kalispell once more, Carole continued the search. At that time, Verne flew back home to take her _______ to look after their other pets. Thankfully, a local family in Kalispell offered to _______ her until she found Katie.

By the time September _______, Carole began to lose hope. She missed her home, husband, and pets, but Verne _______ her to continue looking for one more week.

She then received a _______ from a resident who said that he had seen a border collie in his yard. Carole visited the property, but found nothing — until they _______ a pair of hikers who pointed out a border collie that had been resting under a nearby tree. When Carole called Katie’s name, the dog ran bounding into her arms.
