3 . Loss of slow-wave sleep as you age may increase your risk of developing dementia (痴呆), according to a new study.

“We found that aging was associated with a decline in the amount of the deepest stages of sleep, known as slow-wave sleep. We then found that people with greater declines in slow-wave sleep over time had a higher risk of getting dementia over the next 17 years of follow-up,” said Matthew Pase, senior author of the study.

Slow-wave sleep is the third and fourth stages of sleep, which is important for brain health. During this stage, the body removes unwanted or harmful materials from the brain. “For the brain, this deep sleep is thought to be the most restorative,” said Dr Richard Isaacson, who wasn’t involved in the study.

The researchers wanted to know whether chronic (慢性的) reductions in slow-wave sleep over time are linked to dementia risk in humans and whether dementia-related processes in the brain may contribute to getting less of this type of sleep. They studied 346 people with an average age of 69 and completed two overnight sleep studies—one between 1995 and 1998 and the second between 1998 and 2001—during which their sleep was monitored. The researchers also investigated whether any change in the amount of slow-wave sleep that participants got was associated with developing dementia up to 17 years after they completed the sleep studies. By that time, 52 participants had been diagnosed with dementia. Each percentage decrease in slow-wave sleep per year was linked to a 27 percent increased risk of developing dementia. The rate of slow-wave sleep loss accelerated (加速) from age 60, peaked from ages 75 to 80and slowed afterwards.

“This is an important study yet again showing the impact of quality of sleep on a person’s risk of cognitive decline and dementia,” Isaacson said. “It’s important to not only pay attention to the total amount of sleep a person gets each night, but also monitor sleep quality as best as possible.”

4 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

1. What does the underlined word “depleted” in paragraph 2 mean?

A．Reused.	B．Restored.
C．Explored.	D．Reduced.

2. Why does Julio Cuestas call for new fishing techniques?

A．To cut down on the costs of fishing.

B．To improve the income of local residents.

C．To promote the well-being of marine wildlife.

D．To spread traditional community fishing methods.

3. What is paragraph 4 mainly about?

A．The aim of the changes to fishing methods.

B．The efforts to preserve marine ecosystem.

C．The results the trawl net s have brought about.

D．The impact of fishers on the local environment.

4. What is Julio Cuestas’s attitude towards Acandí’s future?

A．Confident.	B．Uncaring.
C．Concerned.	D．Doubtful.

5 .    Lots of kids like to talk about sports, but Joseph D’Avirro talks about sports like a professional host in a show called Sliders & Curveballs. The 9-year-old from Newington, Connecticut is a natural at sports talk and has been broadcasting the show—which is about baseball, basketball and other sports—with his dad, Mike D’Avirro, since September 2019.

   The D’Avirro started the broadcast after two former college roommates of Mike died, which made Mike want to spend more time with his son. Then the idea came to him. So far, they have done about 50 programs. Joseph’s favorite is when the father-and-son team interviewed Jim Calhoun, the coach leading the Connecticut Huskies to three national titles. They have also interviewed important sports authors.

   The father and son make about one 30- to 40-minute podcast each month. They prepare for the podcasts by deciding on the questions they want to ask the guest. Joseph asks half of the questions, and Mike handles the other half. Joseph reads his questions again and again to get them in his brain well. It is a lot of work, but Joseph says it is “a lot more fun than homework”. Joseph has also learned to speak up and speak clearly. He has to listen and to go with the flow of the conversation. For example, he said, “If the guest is talking about sports in the 1990s, you have to think about sports in the 1990s.”

When asked how long he and his dad will continue doing the show, he answered, “Until my dad starts growing gray hairs.” Joseph has other ambitions when he grows up—to be a sports player, a sports broadcaster or to own a basketball team. Those are big dreams, but Joseph is already living a dream: talking sports and spending time with his dad.

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。

My heart sank when I received the news—no salary again. How would I manage the increasing bills, the groceries and my children’s needs? The future seemed hopeless. With a heavy heart, I hurried to pick up my two children, my mind racing wildly.

That’s when I saw it—a wallet, lying on the sidewalk. It was as if fate had thrown me a lifeline (救生索). Hope came to me as I approached it. The wallet was large, and when I opened it, my eyes widened in disbelief at the sight of a large amount of cash inside it. I hesitated for a moment, torn between the immediate relief that this money promised and the morality (道德) of keeping it.

Curiosity led me to search through the wallet. The things it contained were a photo and a couple of business cards. No matter how much I wanted to take the contents, my moral principles and inner voice told me not to do this. The decision became clear; I couldn’t keep this money. It wasn’t rightfully mine.

I picked out a business card. The name and number were there. With a deep breath, I dialed the number and explained my find to the voice on the other end. The voice came, completely emotionless, warning that they would come to me. He hung up without even saying “thank you”. I was angry with the impoliteness. I even regretted my decision, but my conscience (良知) did not allow me to go back on my choice. I had told the voice where I lived and went to get my children.

Shortly after we arrived home, a large black car suddenly pulled up to our house. The driver got out and knocked on the door. When I opened it, the driver told me that the owner of the wallet wanted me to personally hand over his wallet.

注意：

I didn’t want to do so, but I agreed to go with the driver at last.

Reviews from users

FluentU is a great method to learn a foreign language. We watch videos with subtitles and at any time, we can stop the video if we don’t understand a word or an expression. We click on for additional explanations. Then, we have a quiz to work the vocabulary. I find this method very interesting to improve and stay motivated.

—Estelle Jaouen

I appreciate being able to hear the pronunciation from a male and female voice. I think the mix of characters and pinyin are great and well-balanced. I love the fact that I’ve only been doing this for less than a month and I already know dozens of useful phrases and words!

—Maria van Eeden

I like the fact that it’s very dynamic and not grammar focused. Also, having many videos to learn from makes it even less boring no matter where you are as long as you have a smart phone. I like to just watch each video one time, pause at each sentence and try to remember words and sentences.

—Eduard Marius

The best thing about FluentU is that you have direct context for each new vocabulary that you learn. Repeating the dialogues is the way I learn. Also, that you can bring in your own vocabulary list and that the program searches for videos or material in which the words are included are remarkable!

9 . International Travel

International travel can be a fantastic way to see the world. However, even if you want your journeys to be as exciting as possible, you don’t expect any unhappy things to happen.     1    

Health is the most important thing when you are planning to travel abroad. When you’re going to travel abroad, you may need to get special vaccines (疫苗) to protect you from diseases. If you’re going to any out­of­the­way areas, remember to bring the commonly used medicines with you.     2     So you don’t run out of them while you’re abroad.

    3    For example, if you plan to drive on trips, find out how driving rules may differ. Some countries may have unusual rules or laws that you might break by mistake.So try to learn more about the countries you’re going to visit.

Learn some local language. It’s important to learn something basic (基本的) like “Hello” “Thank you”, and “Where is the bathroom?”.     4    You can check the dictionary first and then ask people simple questions.

Copy your travel documents (文件). All your travel documents should be copied. We live in a digital (数字的) world now.    5    You’d better have the digital copies handy. But make sure to protect your personal information.

A．Good travel is the result of good planning.

B．Basic rules and laws differ in many countries.

C．It’s easy to get digital copies of these documents.

D．Consider buying travel insurance before you travel.

E．There are things you should know about international travel.

F．If you can’t remember them, bring a small dictionary with you.

G．If you take some medicine every day, make sure you pack enough.
