1 . Double rainbows are one thing, but a double aurora (极光)? They can happen, though some kinds are rare. One particular red-and-green aurora is especially confusing. Now, images taken by amateur astronomers may help reveal its secrets.

Citizen scientists living in Canada and Finland used cameras to document an unusual combination of auroras in the night sky. Physicists have studied those images to learn what may have caused the unusual light show.

Alan Dyer was outside his home in Strathmore, Canada, when the dancing Northern Lights caught his attention. He grabbed his camera and started filming. "I knew I had something interesting," says Dyer. At first glance, the double aurora looks like a floating slice of watermelon. The green aurora is well-understood. The fruity looking red st rip is more mysterious. Scientists have known about these red auroras for decades. But there's no agreement on how they form. One idea is that Earth's magnetic field can heat up certain areas of the atmosphere. That heat could knock particles (粒子) around, like in proton (质子) rain.

Researchers had seen these two types of auroras occur together before. But it was always mysterious, says Toshi Nishimura, a space physicist at Boston University. After looking at satellite observations along with the images taken by Dyer and others, Nishimura and his team concluded how the two phenomena might be related. The key is the thin rays in the red aurora. They mark the paths of electrons falling through the Earth's magnetic field. That means electron rain appears to cause the red aurora, just as proton rain causes the green one. Both get powered by the solar wind. But the electrons carry less energy than the protons, so they make for a more reddish color.

Electron rain might not be the only way to produce the stable red auroras, though. The results show that what's going on is more complicated than researchers had thought. The auroras Dyer saw could be danger zones for radio communication and GPS systems, says Nishimura.

The citizen scientists who took the photos were a critical part of the new findings, Nishimura says.

3 . According to the “Geophysical Research Letters” published on the latest research from the North Pole shows that the Aretic is warming at more than four times the rate of global warming. Climate change has not only brought about an increase in the global average temperature, but also led to the trend of frequent, widespread, strong and concurrent extreme weather and climate events.

Greenland is the largest island in the world. About 3/4 of the area is within the Aretic Circle, and 81% of the area is covered by ice and snow. Greenland’s annual average temperature is below 0℃, and the absolute minimum temperature of the coldest month in the coldest central plateau area reaches minus 70℃, which is the second “cold pole” on earth to Antarctica.

Recently, CNN reported that “due to the continuous high temperature in Europe, the large ice sheet above Greenland has shown signs of melting, and the situation is getting worse. In just 3 days, the average daily the amount of ice melted is as high as 6 billion tons.” The melting water during this period is enough to cover 30.48 cm of West Virginia, USA.

At present, the probability of abnormally high temperature in more than 80% of the world is increasing, which is mainly related to the increase in global carbon dioxide emissions. In fact, over the past century, as humans have increased their use of fossil fuels, rising temperatures have made heat waves more frequent.

Secondly, the heat island effect is also an important reason for the increase of urban temperature. People will increasingly use air conditioners to cool down. The main unit of the air conditioner emits heat to the outside, which is equivalent to forming a cycle, causing the temperature in the city to get higher and higher.

Professor Otto, a climate scientist at Imperial College London, said: “In a few decades, this summer may be quite cool.”

1. The article prove the situation of Greenland is getting worse by ______.

A．listing figures	B．making a comparison
C．giving a definition	D．giving examples

2. The major reasons causing high temperature are ______.

A．extreme weather and climate events	B．global warming and ice melting
C．carbon dioxide emissions and fossil fuels	D．carbon dioxide emissions and heat island effect

3. What can we infer from Professor Otto?

A．The temperature in this summer isn’t high.	B．The high temperature situation will only get worse.
C．In the future, the summer will be cool.	D．Professor Otto likes summer very much.

4. The author’s attitude towards the global warming seems to be ______.

A．positive

B．doubtful

C．uncaring

D．negative

5 . Wildlife experts are asking Australians to drive carefully to avoid unnecessary roadkill as native animal numbers drop following years of natural disasters.

Kristie Newton from WIRES said the recent floods across Eastern Queensland and New South Wales could lead to an increase in animal roadkill accidents with wildlife on the move. “This year it might be even worse because they’re traveling a bit further to find food,” Newton said. “Important food sources like grasses have become less and less, forcing many animals to move outside their habitat in search of food, and turn up in unusual places.”

“The fires killed millions and millions of native animals, and now we’ve had the floods. So it’s important that we try and protect what animals we’ve got left.” the wildlife expert said. The 2019-20 bushfires in Australia have affected nearly three billion animals.

According to AAMI Insurance, more than ten percent of all animal roadkill accidents happen in May. More than 15,500 AAMI animal collision claims last year showed that central Victoria’s Heathcote was the country’s most dangerous place for wild animals. Victoria was also the worst state for animal roadkill, with almost one third of animal accidents taking place on Victorian roads. New South Wales and Queensland followed closely behind.

Newton said moving a dead animal off the road can be a good way to prevent unnecessary death. “Birds also come down and feed on those bodies, and we see a lot of them get hit when doing that.” She is also encouraging drivers to do the right thing if they hit an animal. “Please pull over where it is safe to check whether the animal is injured,” said Newton. “For your own safety never set close to an adult kangaroo, even if it’s injured.”

1. What is the main reason for the increase in animal roadkill accidents?

A．People traveling more than before.

B．Animals preferring to feed alongside roads.

C．Cities becoming more attractive to animals.

D．Animals having to move because of natural disasters.

2. What is paragraph 3 mainly about?

A．What damage Australian bush fires have had.

B．Natural disasters make it hard to protect wildlife.

C．Why it is high time people protected Australian animals.

D．Bush fire s are much more dangerous to animals than floods.

3. What information can we get from AAMI Insurance?

A．Most roadkill accidents happened in 2019.

B．Animals in New South Wales suffered most.

C．Queensland took quick action to end roadkill.

D．Heathcote saw most roadkill accidents in Australia.

4. What is the right thing for drivers to do in Newton’s opinion?

A．Leave the dead animal alone.	B．Stop and check on the hit animal.

6 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文，续写词数应为150字左右。

My father never told me he loved me when I was a child. I always saw him as being a serious man who rarely had a smile. But my mom told me “I love you” everyday. So I really never thought about not hearing it from my dad. I never really thought about it much until I faced the reality of death.

On November 9th, 1990, I received word that my National Guard unit was going to the war zone. I had been in the Guard for 10 years and never dreamed that we would be activated for a war, even though I knew it was what we trained for. I went to my father and gave him the news. I could sense he was worried about me going but he said nothing, and eight days later I was gone.

On November 17th,1990, our military vehicles rolled out of rural Greenville, Michigan. The streets were filled with families and well-wishers to see us off. As we were close to the edge of town, I looked out the window of my truck and saw my wife, my children, and Mom and Dad. They were all waving and crying, except for my father. He just stood there, almost like a stone statue. He looked pretty old at that moment. I don’t know why, he just did.

I was gone for that Thanksgiving and missed our family’s dinner. A few days after Thanksgiving I was able to call my wife, and she told me something that has made me look at my father in a different way ever since. She told me that my father recited his usual Thanksgiving prayer. But this time he added one last sentence. As a tear ran down his cheek, he said, “Dear Lord, please watch over and guide my son, Rick, with your hand in his time of need as he serves his country, and bring him home to us safely.” At that point he burst into tears. I had never seen my father cry, and when I heard this, I guessed my father really did love me.

Eight months later, I returned home from the war.

Ever since that day, my relationship with my father was never the same.

8 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

In the beginning, western people use letters of the alphabet (字母表)     1     (write). People who write in Chinese, however, use characters that stand for words or ideas. Historians believed Chinese writing began as early as 1500 BC. The     2     (early) forms were called “Oracle Bone Inscriptions (甲骨文)”. These were animal bones marked with pictures. Besides writing on bones,     3     (mark) on turtle shells was also a way for ancient to record.

By 1400 BC, the Chinese writing system had become more complex.     4     number of its characters was over 2,500. Around 200 BC, almost everyone used the same characters. Even today some modern Chinese characters are similar to     5     (that) from 2,000 years ago. For example, the character that     6     (mean) man in the Lishu system from 200BC is similar to the character from the Jiantizi     7     is used today.

People     8     (make) efforts to change Chinese characters over the centuries. The most important changes happened in the twentieth century. The Chinese government made many characters simple     9     that more people could learn to read. This simpler system is used in most parts of China. with these changes, Chinese writing from 2,200 years ago is still understood today. Many foreigners are interested in     10     (we) Chinese characters.

9 . The curtain has come down on the “2022 My Spring Festival in Shanghai” and “The Shanghai story-telling activity-epidemic (流行病) prevention and control” short-video contests, initiated by the Information Office of Shanghai Municipality and China Daily in August 2022. The contests have actively attracted thousands of international and Chinese students from many universities. The original work of the short-video producers in Shanghai depicted various parts of this metropolitan (大都市的) city.

Behind the scenes, international students spent the Spring Festival with local Chinese friends, and thousands of young people supported Shanghai during the coronavirus outbreak.

“Filming short videos gave me a more grateful perspective on life. Using experience gained in the past, we can work together to create a brighter future,” said Yiqing Hu from Fudan University.

“The video I produced for the short video contest, featured a whole range of emotions, from despair to joy. Through the experience, I learned the full nature of life under epidemic controls.” Ruonan Lu said, a student from Fudan University.

“The Shanghai story-telling activity” has displayed China’s culture, Shanghai’s humanities, technological innovations and ability to hold international people-to-people exchanges.

The event saw local members of young people coming together to discuss youth responsibilities during the complex epidemic prevention and control situation. The activity is hosted by the Information Office of Shanghai Municipality and China Daily, which have together formed s type of International Communication.

This Shanghai strategic communication organization focuses on accurately communicating China’s culture and message to the rest of the world. It’s hoped that better methods of communication will make it possible to construct a global community with a shared future for humankind.

10 . If you’ve ever walked around the streets of a Chinese city and seen sticks of brightly colored fruit shining in the winter sun, chances are that you’ve been at a tanghulu stall.

    1    ? Also called bingtanghulu, it’s a traditional northern Chinese snack made of skewered (串起的) fresh fruit dipped into syrup that hardens quickly, creating a hard shell. Crunchy and sweet on the outside, soft and sour on the inside, this sugarcoated special ty of northern China is a winter favorite with young and old alike.

    2    , many creative traders — and tanghulu lovers at home — will also make it with any number of other diverse fruits like strawberries, grapes, mandarin oranges and pineapple segments (瓣；片).

Tanghulu dates back to the Song Dynasty when it was a favorite with the Chinese imperial family. Legend has it that when a princess in the court fell sick, a doctor suggested she eat hawthorn (山楂) fruit fried in brown sugar every day for two weeks. On her recovery, the doctor became famous.     3    .

Nowadays it’s perhaps the most popular street sweet in China.     4    . When the weather cools, the vendors (小贩) increase, and you can’t avoid seeing them.     5    .

A．So what is tanghulu

B．Why is tanghulu so popular

C．While traditionally made with Chinese hawthorn

D．Tanghulu attracted more and more people’s attention

E．And the snack found a permanent place on China’s streets

F．At the cost of just ten yuan, there’s not much stopping you from trying it

G．You’ll often see street vendors with their long bamboo skewers of shiny candied fruit
