1 . Flash droughts develop fast, and when they hit at the wrong time, they can ruin a region’s agriculture. They’re also becoming increasingly common as the planet warms. In a study published in the journal Communications Earth& Environment, we found that the risk of flash droughts, which can develop in just a few weeks, is on the rise in every major agricultural region around the world in the coming decades.

In North America and Europe, cropland that had a 32% annual chance of a flash drought a few years ago could have a greater chance of a flash drought by the final decades of this century. That result would put food production, energy, and water supplies under increasing pressure. The cost of change will also rise. A flash drought in the Dakotas and Montana 2017 caused $2.6 billion in agricultural damage in America alone.

All droughts begin when rainfall stops. What’s interesting about flash droughts is how fast they strengthen themselves, with some help from the warming climate. When the weather is hot and dry, soil loses moisture rapidly. Dry air extracts moisture from the land, and rising temperatures can increase this evaporative (蒸发的) demand. The lack of rain during a flash drought can further contribute to the feedback processes. Under these conditions, crops and vegetation begin to die much more quickly than they do during typical long-term droughts.

In our study, we used climate models and data from the past 170 years to assess the drought risks ahead under three conditions for how quickly the world takes action to slow the pace of global warming. If greenhouse gas emissions from vehicles, power plants, and other human sources continue at a high rate, we found that cropland in much of North America and Europe would have a 53% annual chance of flash droughts, by the final decades of this century. Globally, the largest increases in flash droughts would be in Europe and the Amazon. Slowing emissions can reduce the risk significantly, but we found flash droughts would still increase by about 6% worldwide under low emission conditions.

2 . 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。

Once upon a time, there lived a poor but cheerful shoemaker. He was so happy that he sang all day long. The children loved to stand around his window to listen to him.

Next door to the shoemaker lived a rich man. He used to sit up all night to count his gold. In the morning, he went to bed, but he could not sleep because of the sound of the shoemaker’s singing. One day, he thought of a way to stop the singing. He wrote a letter to the shoemaker inviting him over for a cup of tea.

The shoemaker came at once, and to his great surprise, the rich man gave him a bag of gold as a gift. The shoemaker took the bag and thanked the rich man. When he returned home, the shoemaker couldn’t wait to open the bag. He had never seen so much gold in his life! He sat down at his bench and began, carefully, to count it. The children watched through the window.

There was so much there that the shoemaker was afraid to let it out of his sight. So he took it to bed with him. But he could not sleep for worrying about it. So he got out of bed and went to hide it in the attic (阁楼), but he was not sure if that was a good place.

Very early in the morning, he got up and brought his gold down from the attic. He had decided to hide it up the chimney (烟囱) instead. But after breakfast, he thought it would be safer in the chicken house. So he hid it there. But he was still uneasy, and in a little while he dug a hole in the garden and buried his bag of gold in it.

For years I     1     (ask) why I volunteer, and my answer remains the same. I volunteer because it makes     2     difference.

Growing up in Hawaii, I saw Dad taking my family downtown to pass out cheeseburgers to the     3     (home), and my passion grew from there. Over the years, I placed my focus     4     food insecurity and that led me to found the first food pantry (食物分发处) on the campus of Indiana University. I will never forget the day when I opened the pantry. A student walked in the door and he said, “I was in class with you     5     (early). Thank you for doing this because I was trying to figure out what I was going to eat this week.” The food pantry     6     (actual) helped many a student on the campus,     7    , for some reason, had difficulty     8     (get) everyday meals. Those who got food from there came back to support our food pantry, making it a place to pass on kindness.

That was two and a half years ago, but     9     (moment) like those stick with me to this very day. Since graduating, I now volunteer with different homeless shelters in Indianapolis, and I will continue to make     10     (me) available as long as there is someone in need.

5 . Sometimes, we meet with situations that cause us to feel angry to the point we may want to erupt like a volcano or curse (咒骂) someone out.     1     Here are some replies online to the question about how to deal with anger.

Go for a swim, lift weights, and practice other forms of exercise!

Science suggests that hearing, seeing, or swimming causes our brain to produce neurochemicals that increase blood flow to the brain and heart. “    2     I like to lift weights. It completely takes the edge off. Heavy bag work is good for cardio and reducing anger. Yoga is great for both exercise and meditation,” wrote u/JackFunk.

Eat a healthier diet.

Proteins such as fish, tofu, and chicken, help us produce higher levels of dopamine and norepinephrine, which are chemicals in the brain that play a role in your mood, motivation, and concentration. “I found that some foods messed with my stomach.     3     Over time I have removed various foods from my diet, and it has really helped,”   u/JackFunk also wrote.

Write your feelings down.

Whether it’s quick sentences or journal entries, writing down how you feel is a great way to release negative emotions. “    4     Pour your heart out… and if you’re worried that someone else may read it later, you can burn it to release the energy,” wrote u/ChoiceFabulous.

    5    

“If you have trouble not getting angry when discussing something or trying to work through a problem with someone, always imagine the conversation is being videotaped. If you keep that in the back of your mind, you will always think about what you say, and it could help keep your mind from the anger,” wrote u/therealtidbits.

A．For me, nothing is better than exercise.

B．Whenever I can’t help getting angry, I read.

C．Pretend that when you get angry people are watching.

D．Whenever I can’t exercise or burn out the feelings, I write.

E．Anyway, there are always better ways to handle when angry.

F．They then messed with my head, which brought out the anger.

G．Pretend there is a camera before you and be mindful of what you say.

6 . When someone tells me that they’re going to spend just 3 days in Paris, I feel like they’re most likely not going to love it. I mean, it’s possible to have a great time if you do it right and put what you want to see at the first place. During such a short visit most tourists head to see the Eiffel Tower, Notre Dame, Louvre and some other tourist attractions, and therefore experience crowds, long lines and not the real local Paris.

Take your pick and spend some time actually enjoying these things instead of rushing through everything. I’m not telling you not to see these famous landmarks, but in order to fully feel the Paris atmosphere, you need to stay in the city longer. A stay in Paris just for a weekend seems far from seeing all the great things.

Almost everyone is dreaming of getting to the top of the Eiffel Tower. But the moment you start approaching the tower you might realize that it’s not very romantic, as it’s surrounded by a ton of visitors and annoying vendors (小贩). The place is crowded, and lines take forever no matter when you visit it.

It’s hard to find a romantic spot unless you book a dinner on top of the Eiffel Tower. It’s something you will only do once, as it’s not the best fine dining you’ve ever had — you’re doing it just for the experience. However, if you climb the stairs behind the Croatian Embassy you may be able to find a quiet spot overlooking the tower. The view is wonderful and definitely worth it, especially at night when the tower starts blinking!

I recommend you to see the city from up high from the top of the Tour Montparnasse, Arc de Triomphe, or even a carousel (旋转木马) in Tuileries, and actually have the Eiffel Tower in your view.

1. What can be inferred from the first paragraph?

A．You can only see crowds at tourist attractions.

B．He who has a short visit doesn’t love Paris.

C．Visitor can have a good time traveling in Paris in three days.

D．It takes more time to experience the real Paris.

2. What is TRUE about visiting Paris according to the author?

A．Fully feeling the atmosphere of the city.

B．Only visiting the famous landmarks of the city.

C．Seeing the whole city at the weekend.

D．Rushing through all attractions in the city.

3. How does a tourist usually feel after visiting the Eiffel Tower?

A．Delighted.

B．Sad.

C．Exhausted.

D．Romantic.

4. Which can be the best title for the passage?

A．The atmosphere of Paris.

B．The tips of visiting Paris better.

C．The view of the Eiffel Tower.

D．The tourist attractions in Paris.

7 . Movie stars might think their lives are private after leaving the acting location, but they ought to know that they have much power over their audience. The power gives them an ability to change people, events, even history, making them to have the responsibility of being good role models.

With time going on, movie stars become celebrities (名人) and in the process get a large number of fans. Some of them follow their deeds, dress, and act like them. In reality, they want to be like their favorite movie stars. If a movie star engages in acts that the society does not approve, those who look up to them, especially the teens, will do the same. Movie stars should be responsible for what they do and say as following the actions is now simpler because of social media. It is important to behave like a role model even when they think no one is watching.

Nobody is perfect, and movie stars also have had their down moments. They may not have been good role models at the time, but they can change the narrative by doing the right things. They can also turn the past shortcomings into positives by opening up about problems and how they overcame the challenges. And their audience can learn to discuss their problems and seek help.

People starring in movies are the target of companies to promote their products or services for a fee. Their celebrity status is a reason enough to think beyond the payment. A movie star should not recommend something that will influence the way teens live negatively. It would be wrong to promote something like sweetened drinks or foods without health benefits. Movie stars face problems like other people, but because of their influence, they have a responsibility to be role models in the public eye.

9 . According to a new USDA(the U.S.Department of Agriculture)report,U.S.forests could worsen global warming because they are being destroyed by natural disasters and are losing their ability to absorb planet-warming gases as they get older.The report predicts that the ability of forests to absorb carbon will start declining after 2025 and that forests could release up to 100 million metric tons of carbon a year as their emissions from decaying(腐烂)trees go above their carbon absorption.Forests could become a“substantial carbon source”by 2070,the USDA report says.

The loss of carbon absorption is driven in part by natural disasters such as wildfires, tornadoes and hurricanes,which are increasing in frequency and strength as global temperatures rise.The disasters destroy forestland,destroying its ecosystem and decreasing its ability to absorb carbon,according to Lynn Riley,a senior manager of climate science at the American Forest Foundation.Aging forests also contribute.The report found that older,mature trees absorb less carbon than younger trees of the same species,and U.S.forests are rapidly aging.

This trend is likely to continue,as forests come under increasing threat from climate change and exploitation(开采).The typical tropical forest may become a carbon source by the 2060s,according to Simon Lewis,professor in the school of geography at Leeds University. “Humans have been lucky so far,as tropical forests are cleaning up lots of our pollution,but they can’t keep doing that indefinitely,”he said.“We need to cut down fossil fuel emissions before the global carbon cycle starts working against us.”

U.S.forests currently absorb 11 percent of U.S.carbon emissions,or 150 million metric tons of carbon a year,equal to the combined emissions from 40 coal power plants,according to there port.The loss of forests as natural carbon absorbers will require the U.S.to cut emissions more rapidly to reach net zero.“As we work to decarbonize(碳减排),forests are one of the greatest tools.If we were to lose that tool,it means we will contribute that much more in emissions,”Riley said.

1. What is the main finding of the report?

A．Forests are suffering from decaying trees.

B．Forests could contribute to global warming.

C．Forests are being destroyed by natural disasters.

D．Forests have become substantial carbon absorbers.

2. What is paragraph 2 mainly about?

A．The key role of forests in the ecosystem.

B．The consequences of frequent natural disasters.

C．The impact of rising global temperatures on forests.

D．The reasons for forests’ declining ability to absorb carbon.

3. What is Simon Lewis’ suggestion on addressing the problem?

A．Reducing fossil fuel emissions.

B．Cleaning up decaying trees in time.

C．Planting trees on a large scale.

D．Limiting the exploitation of forests.

4. What does the author intend to do in the last paragraph?

A．To offer suggestions on forest management.

B．To stress the significance of forest protection.

C．To present the efforts made to reach net zero.

D．To show the carbon emissions from coal power plants.

A groundbreaking new app from the Changsha IFS mall shows     1     much 5G is transforming the shopping experience.

    2     updating clothes or comparing prices, mobile technology has transformed the shopping habits of     3     (today) customers. 5G is bringing the mobile revolution into real-world shopping.

In China’s Changsha, Changsha IFS became the first 5G-enabled     4     (commerce) complex in the country. And it’s using a new shopping navigator (导航), iGO, whose role isn’t just help users find their way around the mall’s different     5     (level). Users can even enjoy a personalized shopping experience and engage in an interactive treasure hunt game.

Common phone navigation tools can be tough     6     (use) within complex indoor environments. However, the iGO system, which opens directly from WeChat, uses the smartphone camera to capture the user’s precise     7     (locate).

Once a destination     8     (select), the navigator starts to guide shoppers through their environment step by step. IGO combines 5G technology with Augmented Reality so that navigation markers appear on top of the real environment,     9     (mean) shoppers can easily navigate, turn by turn and floor by floor,     10     having to puzzle out how the blocks on a map relate to where they are in the real world.
