1 . Many people think that being healthy is a difficult task that involves lots of dieting and time at the gym.     1     By supporting your body and mind, making some simple changes to your routine, and setting small goals for yourself, you can be on the path toward living a healthier, happier life.

Drink more water. Adults should drink 2-3 liters of water per day, while children should drink 1—2 liters.     2     Water keeps your body at the correct temperature and removes poison and maintains homeostasis（体内平衡）. Water also clears your skin, helps to control your appetite, and keeps you energized.

    3     Every time you get moving you put yourself at risk for injury, so make sure you’re doing it right! You should always be drinking water during your workouts. Take breaks! It isn't being lazy; it's being healthy. After 30 minutes or so of exercise, grab your water bottle and lighten up. Your body needs a second to catch up. You'll be able to go further in the long run.

Think positively. A simple positive change on a situation can turn an challenge into an opportunity. Not only will you have more interest for life, but your immune（免疫的） system can also fight off colds and heart disease better!     4     Think of two things you’re grateful for. Eventually, your mind will notice the pattern and stop the negativity before you have to do it.

Get a good night's rest. Getting too little sleep or poor-quality sleep not only makes you easier to get sick, but also increases the time you need to recover from illness. When you sleep well, you can wake up ready to go and be more active all day.     5    

A．Exercise wisely.

B．But that’s actually not true!

C．To start this difficult step, focus on gratitude.

D．That is in addition to other drinks like tea or coffee.

E．So sleeping properly is very important for your health!

F．Soon, you'll start to see your healthy life taking shape!

G．So instead of walking quickly on Wednesday, go to hit the pool.

2 . 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。

Facial surgery (手术) is a serious business, especially on children     1     are not yet fully grown but Melbourne researchers are developing a technique that could change the face of children’s surgery.

This new     2     (develop) will allow doctors to work out a child’s normal face shape at different ages to predict (预测) future growth.

Researchers at the Murdoch Children’s Research Institute (MCRI) could soon replace the ruler currently     3     (use) to track changes in a child’s head and face with 3D images. By     4     (improve) the ability to predict normal growth and future changes in a child’s face, doctors will be able to    5     (well) complete their surgery than before.

MCRI’s Mr Harold Matthews said current     6     (method), including using patients’ photographs and X-rays were slow. Together     7     researchers in Belgium, Mr Matthews is pioneering a new tool that provides averages (平均值) for normal growth of the face throughout childhood.

The project intends     8     (take) some of the guesswork out of surgery. For example, in children with Pierre Robin Sequence, a serious condition which means they are born with an underdeveloped jaw(下颚), some doctors choose to fix it early while others wait to see if the child’s face will     9     (natural) correct itself as it grows. Without this new technology,     10     is difficult to know which method is better for each child.

4 . I couldn’t sleep at all last night, and my sister believes it was because I ate a bowl of really spicy (辛辣的) food before bedtime. However, I was skeptical about the connection between spicy foods and sleep. Can eating spicy foods before bedtime truly impact one’s sleep quality? Some people believe that eating spicy foods before bedtime can disrupt sleep by increasing body temperature and causing heartburn. It may be worth avoiding spicy foods close to bedtime.

To find out the relation, the researchers in Australia conducted an experiment to investigate the effects of spicy foods on sleep. They provided a group of individuals with delicious late-night meals, alternating (交替) between spicy and mild options. The results revealed that consuming spicy foods led to disrupted sleep patterns, causing participants to take longer to fall asleep and sleep for shorter time. This data supported the belief that there is a correlation between eating spicy foods and experiencing sleep disturbances.

While the exact mechanism(机制)by which spicy foods influence sleep remains unclear, researchers have proposed several possibilities. One is that stomach discomfort resulting from spicy food consumption may affect sleep quality. Additionally, the long digestion (消化) of spicy foods could delay the start of sleep. Furthermore, spicy foods contain something that can raise body temperature, which has been linked to poor sleep in previous studies.

Given these findings, it is advisable to avoid consuming spicy foods before bedtime to promote better sleep. Next time, I will follow my sister’s advice and opt for a milder meal in the evening to ensure a restful night’s sleep.

5 . On Monday, a lawsuit (诉讼) in the US got huge headlines around the world. It deals with a truly 21st century issue—whether human genes (基因) may be patented.

Myriad Genetics, a biotechnology company, discovered two genes — BRCA 1 and BRCA 2 — that are highly related to breast cancer. Myriad patented its discoveries and a group of researchers challenged that the patent was illegal.

The US patent law protects the temporary economic rewards inventors get from their inventions. But it also says a product of nature or a law of nature can’t be patented. For example, Einstein couldn’t patent on his discovery of E=mc².

And until relatively recently, many of the medical researchers voluntarily gave up patents on their inventions. When Dr. Jonas Salk, the inventor of the polio vaccine (小儿麻痹症疫苗), was asked in 1955 whether he had a patent on the vaccine, he replied, “Could you patent the sun?”

Myriad Genetics, however, says that the genes it identified are not like the sun. It notes that there are 20,000 genes in the human body and that it has sorted through all those genes and found the two that are closely related to breast cancer.

Not so, say those challenging the patent. Human genes are products of nature. They are just a part of the human body. “All Myriad does is take the part out of the body,” says the challengers’ lawyer, Christopher Hansen. “Can the person who first takes the heart out of the body patent on hearts?”

Rochelle Dreyfuss, a patent expert who is not associated with this case, is a little more down to earth. “At some level it is about money,” he says, “because medicine doesn’t happen for free. The patent system is very important to encourage companies to spend more money on scientific research and development.”

Then how do other countries handle this tricky situation? Most countries approve patents on genes, but they also allow other scientists to use the genes freely to do research and develop new medicines and testing methods.

1. Which of the following can be patented according to the US patent law?

A．The law of gravity force.	B．A unique orbit found in space.
C．A new medicine based on BRCA 1.	D．The basic working principle of planes.

2. What is Christopher Hansen’s argument against the patent?

A．A product of nature can’t be patented.

B．Public interests should be put before profits.

C．It is unacceptable to the other countries in the world.

D．The connection between genes and cancers is not obvious.

3. What does the underlined phrase “down to earth” in paragraph 7 mean?

A．Angry.

B．Rude.

C．Smart

D．Practical.

4. What is the last paragraph mainly about?

A．The consequences of the lawsuit.	B．Other countries’ solution to the case.
C．The public reactions to the news.	D．Some scientists’ support for the patent.

6 . We’ve had weather forecasts for decades. Forecasting our near-term health is far tougher. Yet knowing early that we may be coming down with the flu could be very helpful. The good news is that wearable technology, such as smartwatches, is beginning to provide such information. The smartwatch-like systems contain sensors that collect data.

Jessilyn Dunn is a biomedical engineer at Duke University in Durham. Her team asked 49 volunteers to wear wristbands before and after they received a cold or flu virus. At least once per second, these wristbands recorded heart rates, body movements skin temperatures and more. After analyzing the data, Dunn’s team found that in nine out of very ten volunteers, there were signs of developing illness at least a day before symptoms (症状) appeared.

The early warning, says Dunn, can head off severe symptoms that otherwise would send some people into hospitals. And knowing you’re sick before you have symptoms can warn you to lie low so you can reduce the chance of spreading your disease.

However, these systems aren’t yet ready for the real world, notes virologist Stacey Schultz-Cherry. “This is exciting but also very preliminary (初步的),” says Schultz-Cherry. “Much more work is needed before this approach can be rolled out on a larger scale.” One challenge is that many infections (感染) have analogous symptoms. Actually, besides viruses, many other things also lead to signs of a cold or the flu. Examples, Schultz-Cherry notes, include food poisoning and seasonal allergies (过敏反应). Likewise, heart rates also respond to things that have nothing to do with infections. Examples include exercise and scary movies.

Researchers expect continued improvement in prediction accuracy (准确性). Future models will show signs of developing illness. And researchers will adjust those models by analyzing how well they predict effects on thousands of people.

1. What did the research find out about wearable technology?

A．It tended to give wrong information.

B．It helped give early warnings of disease.

C．It kept track of people’s use of smartwatches.

D．It was likely to make people lead a stressful life.

2. What’s the advantage of smartwatch-like systems according to Dunn?

A．They can reduce the harm caused by illness.

B．They will remind people to keep away from sick people.

C．They can give people the confidence to fight against illness.

D．They will encourage people to develop good living habits.

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

A．Clear.

B．Similar.

C．Mental.

D．Serious.

4. What can we infer about the systems from Schultz-Cherry’s words?

A．They can predict disease with high accuracy.

B．They can be used for checking various infections.

C．They may influence the normal heart rate of people.

D．They have a long way to go before being widely applied.

7 . Is there any such thing as a salt tooth? We are familiar with a sweet tooth, along with the negative effects of sugar. We are broadly aware of the disadvantages of too much salt, including high blood pressure, which puts pressure on the blood vessels (血管), the heart and the kidneys. It can also lead to water retention (水肿). But we don’t tend to police how much salt we eat — at least, not as rigorously as with sugar — or question whether we are just paying attention to our bodies, which require some salt for muscles to work properly, or we are being controlled by a strong urge.

A salt tooth is quite unlike a sweet tooth. It doesn’t create an appetite for itself at the hormone level. But salt does make our taste buds (味蕾) get used to it, so that the more you eat, the more you need to get the same salty hit. This is why chefs can get heavy-handed with it.

As Sam Bloom, a nutritional therapist, explains, “What is generally more concerning is the fat that is used together with salt, like salty crisps, fries and fast food. Ready meals are often the worst for hidden salts. Anything that adds flavor that isn’t a spice or herb will probably have salt added to it and can make you want to eat more because it tastes good. The salt and fat combination in these foods is what causes problems with cholesterol (胆固醇). The salt that people add to a meal is much less concerning.”

Nutritionists’ suggestion is convincing: When the desire for salt hits, avoid going straight for salty snack foods such as crisps and instead ensure you are well hydrated. Seek out whole foods, such as olives and leafy greens. These foods will help you alleviate the desire for salt, which may often be due to a desire for nutrient-rich food.

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

A．Generally.

B．Strictly.

C．Largely.

D．Pleasantly.

2. Why is salt different from sugar according to paragraph 2?

A．Salt attracts chefs.

B．Salt gets people adapted.

C．Salt can change hormone level.

D．Salt generates a special appetite.

3. What is Sam Bloom’s attitude towards ready meals?

A．Objective.

B．Approving.

C．Negative.

D．Ambiguous.

4. What does the last paragraph mainly talk about?

A．Ways of seeking out whole food.

B．Reasons for getting the desire for salt.

C．Attitudes towards seeking for nutrient food.

D．Approaches to relieving the eagerness for salt.

8 . For night owls like Chen Danhong, 28, who works for a technology company in Beijing, the day really just begins after about 8 pm, a psychological hint that she can relax. “When I get home, I’m feeling worn out and tired, but that suddenly turns to excitement and I go on the Internet, read novels or watch movies. I’ll be playing video games and continually saying to myself, ‘OK, this is the last one’ before I eventually realize that it’s 2 o’clock,” says Chen.

Common symptoms (症状) include falling asleep later than 2 am, with the average time taken to fall asleep being more than one hour. Young people in cities are most vulnerable to such symptoms, according to the 2020 Chinese National Healthy Sleep White Paper. Common causes are loneliness, overtime sequelae (后遗症), excessive stress and emotional disorders. On March 21, World Sleep Day, a newspaper, Nanguo Morning News, conducted a survey that attracted 2,000 interviewees.

According to the survey, the reasons for going to bed late vary widely, with overtime work or taking care of a baby accounting for just five percent of the interviewees’ answers on this question. Sixty-four percent said they sleep late because they watch dramas, various shows, read books or play with their mobile phones. Fourteen percent said they do not want to go to bed too early even if they have nothing to do.

Many interviewees said they have had experience of the dangers of going to be late. Twenty-three percent said they have no serious physiological problems, but they can feel weak, are easily fatigued and have a poor complexion. Twenty-one percent said they are forgetful and find it hard to concentrate on work. More worrying is that an unwillingness to sleep can lead to a vicious circle (恶性循环), and15 percent of the respondents said they cannot fall asleep even if they want to.

1. Why does the author mention Chen Danhong’s situation in the first paragraph?

A．To lead in the topic.	B．To present an argument.
C．To shock the reader.	D．To raise a question.

2. What makes young people tend to go to bed late?

A．Unwillingness to sleep.	B．The various entertainments.
C．Caring for their family.	D．The frequent overtime.

3. What does the underlined word “fatigued” in the last paragraph mean?

A．Concerned.

B．Exhausted.

C．Focused.

D．Sleepy.

4. What can be inferred from the passage?

A．Young people are more strong enough to sleep late.

B．Young people can fall asleep anytime they want to.

C．Going to bed late affects many people’s health or work.

D．Sleeping late occasionally isn’t harmful to our health.

9 . Ms. McIntyre, 38, worked as a publisher. She suffered brain cancer and her health got worse despite some medical treatment. But she realized that in a way, she was luckier than some other people. She had insurance to help pay for her medical care. But Ms. McIntyre and her husband, Mr. Gregory, knew that many people with cancer face tough decisions because of the costs of medical care and wind up owing far more than they can pay.

Though her health was failing, Ms. McIntyre decided to help pay off the medical debts of as many people as she possibly could. The couple began donating money to a group called RIP Medical Debt, which is committed to working to pay off the unpaid medical debts of others. The group can pay off medical bills for about 100 times less money than they cost. In other words, for every 100 donated, the group can pay off 10,000 in unpaid medical bills.

Unfortunately, Ms. McIntyre passed away before long. Mr. Gregory posted a message for Ms. McIntyre on her social media accounts. “If you’re reading this, I have passed away,” the post began. Then the post explained, “To celebrate my life, I’ve arranged to buy up others’ medical debts and then destroy the debts.”

The couple had set up a page on a website to raise money for this purpose. They had hoped to raise about $20,000. Nevertheless, Ms. McIntyre’s last post attracted a lot of attention. The donations on her web page quickly passed the total goal. In less than a week, the site had raised 10 times more than expected and the donations are still coming in. By November 22, 2023, Ms. McIntyre’s web page had raised over $627,000, or enough money to pay off about $60 million in medical debts.

Mr. Gregory planned a special event in December to celebrate Ms. McIntyre’s life and to announce how many millions of dollars of medical debts her efforts had paid for.

1. Why did Ms. McIntyre feel luckier than some other people?

A．The doctors eventually cured her.	B．Her disease didn’t become worse.
C．She had a decent job before being ill.	D．She had security about medical care.

2. How did Ms. McIntyre and her husband help others?

A．By paying for their daily debts.	B．By giving away money to them.
C．By ridding them of debts from treatments.	D．By purchasing medical insurance for them.

3. What is paragraph 4 mainly about?

A．The public involvement.	B．The couple’s commitment.
C．The operation of a website.	D．The increase of medical debts.

4. Which of the following words can best describe Ms. McIntyre?

A．Humorous and elegant.	B．Influential and understanding.
C．Cautious and promising.	D．Enthusiastic and adaptable.

10 . As is known to all, sports are necessary, but many people are worried about getting hurt in sports. The equipment（装备）you wear while taking part in sports and other activities is key to avoiding injuries（受伤）.

Start with helmets（头盔）. They’re important for sports and activities such as football, baseball, softball, biking, horseback riding, skateboarding, inline skating, skiing, and snow boarding—to name just a few.    1    Every helmet should be replaced after any accident, as there can be more problems you can’t see.

    2    Sports participation（参与）is the leading cause of eye injuries in teens, but proper fitting protective eyewear can reduce the risk of serious eye injury by 90%. Don’t just wear your regular glasses when you’re on the court or field.    3    

Wear a mouthguard if you play a contact sport where head injury is a risk, such as football, basketball, volleyball and boxing.    4    They can be fitted for your mouth by a dentist（牙医）or bought at sports stores.

And last but not least, the right footwear can keep you from tripping and falling. You know that sports like football, baseball, softball, and soccer require cleats（防滑鞋）.    5    Ask your coach or doctor what shoes are best for your sport.

A．They don’t provide protection.

B．Need to find the right helmet size for you?

C．Eye protection is also a must for many sports.

D．Helmets reduce the risk of head injuries by 75% - 85%.

E．Mouthguards can protect your mouth, teeth, and tongue.

F．The right kind of equipment is important, so is the right size.

G．But you may not realize that sports like biking need special types of shoes, too.
