1 . A recent research suggests that artificial intelligence (AI) could hold the potential for predicting sudden cardiac (心脏的) death and assessing an individual’s risk to potentially prevent future deaths. This development may mark a novel step towards prevention and global health strategies.

Professor Xavier Jouven, lead author of the study, said, “Sudden cardiac death, a public health burden, represents 10% to 20% of overall deaths. Predicting it is difficult, and the usual approaches fail to identify high-risk people, particularly at an individual level. We proposed a new approach.”

The scientific team employed AI to analyze medical data obtained from registries and databases in Paris, France and Seattle. They examined records of 25,000 individuals who had experienced sudden cardiac arrest and compared them with data from 70,000 people from the general population. The matching process involved age, sex and residential area. Using AI, the scientists created about 25,000 personalized health models to evaluate the data and identify individuals at high risk of sudden cardiac death. Additionally, they established a risk file for each participant in the study.

The AI analysis was able to identify people who had more than 90% of risk dying suddenly, and it can predict about more than one-fourth of all cases of sudden cardiac death. “We have been working for almost 30 years in the field of sudden cardiac death prediction. However, we did not expect to reach such a high level of accuracy,” said Jouven, who is the founder of the Paris Sudden Death Expertise Center.

Jouven added. “While doctors have efficient treatments, the use of AI is necessary to detect in a given subject a succession of medical information registered over the years. We hope that with a personalized list of risk factors, patients will be able to work with their clinicians to reduce those risk factors and ultimately decrease the potential for sudden cardiac death.”

2 . A study came out just a few days ago that found people who eat healthily about 80 percent of the time have a high protection on brain health.     1    

It doesn’t mean that you should just go to crazy 80% of the time. But be more aware that you are more likely to stick to a healthy lifestyle if there’s some relaxation here and there. That’s all part of living.

My name is Mark Mailstein and I’m a brain health researcher and the author of The Age-proof Brain.

    2    

For breakfast, I try to eat oatmeal(麦片粥).Usually it’s the quick, the instant, but make sure that it’s not the type with any added sugar.     3    

And then lunch and dinner. I pretty much try to keep really simple. I will look at my plate and have some sort of lean meat. I eat a lot of fish and chicken. And I really just try to think of mixed vegetables, like really colorful plates of fruits, vegetables you know.     4     There are these interesting studies that show it’s the combinations of different types of vegetables, so I try to mix them in.

Sometimes I think something that might be surprising is that I might have a smoothie(奶昔) for dinner as a way to get all those vegetables in. My go-to smoothie is that I take broccoli (西兰花).     5    And I throw carrots and all sorts of vegetables in there.

A．I really like sweet potatoes.

B．They scored really high on memory tests.

C．I try to keep it pretty simple in terms of eating.

D．Your diet can definitely improve your brain health.

E．There’s more evidence that you get more brain health benefit.

F．People always ask what’s the best fruit and vegetable for my brain.

G．So, no additive because we know those additives are not beneficial for brain health.

Online grocery shopping is convenient and continues to grow in popularity. But a new study     1     (publish) in Public Health Nutrition shows that many online products do not have information about ingredients or nutrition     2    (fact), which is a huge miss.

Required information was present, obvious and readable for only 36. 5% of observations.     3     is even more troubling, researchers say, is that non-required information, such as claims like “low in fat” or “organic”, was displayed on 63.5% of the products.

Labeling information     4     (be) important for all consumers so they can make informed (明智的) choices when grocery shopping. People may use the information label     5     (determine) sodium and potassium (钠和钾) to manage heart or kidney disease or may focus     6     sugar, fiber, or carbohydrates to manage diabetes (糖尿病).

Food retailers should     7     (immediate) change their practices and disclose the full information label clearly, consistently and readably. “    8     (difficult) in finding necessary information on some products could actually pose (引起)     9     immediate danger of a severe reaction or even death to the most sensitive consumers,” a researcher says.

The researcher also points out the availability of food labels     10     (make) a difference to the quality of our food choices at the population level. Not having this information potentially weakens the general public health.

5 . More and more people are turning to a plant-based lifestyle.     1     . It has been shown to help improve overall health, prevent diseases, and increase well-being and happiness. Here are two tips on how to gradually move into plant-based living.

Ease Yourself Into It

    2     . This isn’t necessary and it’s too hard—it’s because they’re not giving their body time to ease into it.

If you’ve been eating meat daily (or almost daily) for most of your life, then your body’s going to be a bit confused when it’s suddenly not getting its regular fix of meat. The best way is to gradually reduce meat from your diet. If you eat meat 3 meals a day, drop it down to 2 meals for a couple of weeks.     3     . After that, you can alternate (交替) between “meat days” and “non-meat days”, until you’re comfortable going long stretches without eating meat.

Make Sure You’re Getting Your Nutrients (营养)

If you’re going to be plant-based, you have to do much work. That means figuring out how to develop meal plans that allow you to get your daily doses of proteins, fats, vitamins and minerals. You can’t just switch to eating green salads for 3 meals a day and expect to feel good, because you won’t. You’ll need to start eating a varied diet. Whole grains, like beans and legumes, as well as soy foods, can help you get your daily requirements for protein.     4    

That’s really all you need to know: make sure that you’re taking it easy and giving your body time to adapt, and make sure that you’re getting necessary nutrients.     5     , you’ll be able to enjoy plant-based living in no time.

A．Once you have a clear idea

B．As long as you’re doing these two things

C．These two nutrients are difficult to get from plants

D．Next, bring it down to a meal a day for a few weeks

E．Healthy fats can come from things like olive oil and peanuts

F．The benefits of a plant-based lifestyle are seemingly endless

G．A lot of people fail because they move straight up into a plant-based lifestyle

7 . How To Exercise Your Brain

Just like your muscles- your brain needs exercise to keep it in good working order.     1     Although results are mixed on increasing actual cognitive（认知的）function, learning something new, working your memory, and reading are all great ways to work your brain to its limit!

Learn something new. Keep your brain stimulated and active by picking up a new habit. Practising something new forms new neural（神经的）pathways in your brain.     2     If you’re learning a new instrument, practise playing it every day. Start with small actions and do them repeatedly to train your brain and make it a habit.

Use your memory. It’s not as essential（必不可少的）to commit things to our brain as it once was, but the practice of remembering things can improve brain function.     3     Memorize a few of your closest friends’ phone numbers to exercise your memory.

    4     While you may feel like you are accomplishing more by multi-tasking, you are actually more likely to make mistakes and get frustrated when things go wrong. By not multitasking, you can train your brain to focus your attention on one activity at a time and do better work.

Read every day. Reading a thrilling book can actually enhance your cognitive function. Reading also helps to develop language skills and increase attention spans.     5     Pick up a book, magazine, or newspaper and get reading!

A．Stop multi-tasking.

B．Change your opinion.

C．The more you use your brain, the better it will work.

D．Repetition is one of the best ways to engage your memory.

E．Try to read a little bit every day to enjoy the brain benefits.

F．There are some good ways to make sure your brain stays healthy.

G．This will train your brain to think differently and more creatively about various situations.

8 . Does Drinking Alcohol Make You Gain Weight?

If you are trying to maintain a healthy weight, the first step is to look at what you’re eating regularly and assess whether it helps you meet your nutritional goals.     1     What you drink is a big factor as well, so there are a few things you may want to know about alcohol intake and body composition.

Alcohol’s high in calories.

In general, alcohol is high in calories.     2     When you look at mixers like juices, soda, cream, whipped cream? or coconut milk, the calories in an alcoholic beverage can be really high.

    3    

Hormones（荷尔蒙）play a crucial role in the healthy functioning of all the body`s tissues and organs. Drinking alcohol can impair the functions of the brain parts that release hormones and the functions of the tissues targeted by those hormones, which can result in a range of health issues.

Alcohol makes it harder to get quality sleep.

    4     However, consumption of alcohol—especially in excess—has been linked to poor sleep quality and duration. In fact, individuals who are dependent on alcohol commonly experience insomnia（失眠）symptoms.

It can make you feel hungry.

After a couple of drinks, you're more likely to grab whatever quick and easy snack without really thinking about it.     5     First of all, alcohol can cause blood sugar levels to dip. Also, it's found that alcohol affects an area of the brain that controls appetite and this can cause intense hunger after drinking.

There's also evidence that excessive alcohol consumption has been linked to an increased risk of cancer, heart disease, mental illness, and other problems.

A．It's not unusual for people to use alcohol as a sleep aid.

B．Protein and carbohydrates have 4 calories per gram but alcohol has 7.

C．Those hunger pangs are caused by a couple of different things.

D．But it`s not just about food.

E．Alcohol keeps your body from burning fat.

F．Those intense hunger cues can make you reach for high-calorie foods.

G．It messes with your hormones.

9 . Vegans are persons who don’t eat meat, fish, eggs, dairy, and other animal products from their diet. The average parent who is not a vegan often is concerned when their child decides to become vegans, wanting their personal physician to talk their child out of it. Will their child get enough nutrition(营养) being a vegan? Don’t kids have to eat meat to get enough protein(蛋白质) in their diet?

Although not for everybody, a vegan diet does indeed have many health benefits, and if well planned, it can be a healthy diet for kids. One shouldn’t be crazy when talking about possible health benefits of being a vegan, though. Evidence doesn’t suggest that kids raised on a vegan diet are sick less often than other kids. Not all vegetarian foods are healthy—some are high in sugar, saturated fat(饱和脂肪), or cholesterol(胆固醇).

The vegan diet is typically low in cholesterol and saturated fat and is high in fiber and may lead to a lower risk of heart disease, high blood pressure and other diseases.

These health benefits led Dr. Benjamin Spock to recommend a strict vegan diet for all children over the age of 2 years, which advised that children shouldn’t be given products made from milk after they are two years old and that they can get plenty of protein and other nutrition from vegetables, beans, and other plant foods that avoid the fat and cholesterol that are in animal products.

Dr. Spock’s advice created a lot of arguments. It’s not because experts questioned the health benefits of a vegan diet, but they thought that parents might not take enough time and effort to plan a vegan diet that included enough nutrients to ensure the best growth in their children.

1. What is the characteristic of a vegan diet?

A．It’s a diet without animal products.	B．It’s a diet of being rich in cholesterol.
C．It’s a diet of being rich in fat.	D．It’s a diet of being low in meat.

2. What is Dr. Spock’ suggestion about the diet?

A．Parents need less time to prepare meals for children.

B．The vegan diet is widely accepted by most parents.

C．Children over 2 years old should avoid vegetable fat.

D．Children over 2 years old shouldn’t eat animal products.

3. What is introduced in the last paragraph?

A．The origin of a strict vegan diet.	B．The effort to make a nutritious diet.
C．The difficulty of planning a strict vegan diet.	D．The details of ensuring enough nutrients for children.

4. What is the suitable title of the text?

A．How to avoid the fat from the diet.	B．Health benefits of vegan diets for kids.
C．The shortcoming of eating meat for kids.	D．How to create more nutrients for children

10 . 17-year-old Dasia Taylor was named one of 40 finalists in the Regeneron Science Talent Search (STS), the nation’s most famous Science and math competition for high school seniors.

Dasia’s sutures (缝合线) work by changing color if the patients’ pH level changes, indicating an infection. pH is one of the most common parts of wound healing, Dasia said. It changes very quickly, so it’s one of the fastest ways to recognize infection.

So, she started experimenting with root vegetables. “I found that beet changed color at the perfect pH point,” says Taylor. “That’s perfect for an infected wound. And so, I was like, ‘Oh, okay. So beet is where it’s at’.” Beet provided the perfect dye for her invention, changing from bright red to dark purple when a surgical wound becomes infected. After more than a year of research, Taylor is working on getting her sutures patented.

She imagines these sutures being used in developing countries where they can save lives and money. “The goal of my project is to reduce the number of deadly surgical site infections in developing countries because developing countries suffer from the most number of deaths due to surgical site infections,” she said. “I was like there is no way that that should be happening. The equity part of my brain and all the work that I do around equity was like ‘That shouldn’t be happening. They should have the resources to save their citizens in their country.’ So, my goal is to work on that and make sure that it can actually discover those types of infections and stuff.” After graduation, Dasia hopes to attend Howard University, study political science and finally become a lawyer.

1. How can a patient quickly know if a wound is infected?

A．By observing the pH test paper.

B．Through the doctors’ examination.

C．By looking at sutures’ color changing.

D．By observing how the wound changes.

2. What did Dasia discover in her experiment?

A．Beet has the same pH level.	B．Beet can change color at different times.
C．Beet therapy is good for wound healing.	D．Beet can be used to help her with the invention.

3. What can we learn about Dasia?

A．She has won the invention patent.

B．She became the winner of the Regeneron STS.

C．She made contributions to surgical infection recognition.

D．She helped save lots of lives and money in developing countries.

4. What will Dasia’s future career probably involve?

A．Medical and health work.	B．Medical device development.
C．Something about the legal aid.	D．Medical and science research.
