1 . From crystal-blue lakes to snow-capped mountains and thousand-year-old trees, Canada’s nature is admired around the world. Now it might also be just what the doctor ordered. An ambitious new programme allows doctors to write prescriptions (处方) for free annual passes to Canada’s national parks, encouraging their patients to improve their health — both mental and physical — by taking a stroll in nature.

The prescriptions are provided by PaRX, in partnership with Parks Canada. The first passes were handed out last month, giving holders access to more than 80 national parks, historic sites and nature reserves. PaRX, a health initiative (倡议) launched in 2019 by the British Columbia Parks Foundation, notes on its website that spending time in nature can lead to longer lives, increased energy, reduced stress and anxiety, improved heart health, less pain and better mood. Vitamin D from the sun’s rays has proven health benefits. The organization also hopes that the prescriptions will boost investment in conservation in Canada.

The initial provision covers four Canadian provinces: British Columbia, Saskatchewan, Ontario and Manitoba. Participating doctors have only 100 annual passes to hand out for now, but PaRX hopes that the programme will be expanded.

“Medical research now clearly shows the positive health benefits of connecting with nature,” Steven Guilbeault, the environment minister, said. “I am confident this programme will quickly show its enormous value to the well-being of patients as it continues to expand throughout the country.”

Canada’s physicians are already in the habit of prescribing “nature therapy” as a treatment for anxiety, depression, high blood pressure, immune function and insomnia (失眠). Previously, though, they would write more general prescriptions, such as spending time in nature twice a week, for at least 20 minutes at a time. This is the first time that they have been able to equip their patients with tickets.

2 . Fear of Puberty(青春期)

When young people get to puberty, it causes the physical and mental changes that can bring stress and even fear to them.     1    

Consider how often you worry about it. If it regularly happens more than twice a day, it’s time that you started taking the problem seriously. You should look out for feelings of panic when you think about puberty. You may have frequent stressful dreams or feel depressed when you notice changes in your body.     2     By identifying them, you can start to do something about them.

    3     If you have had a happy childhood it’s natural to feel sad that it’s coming to an end. Many aspects of adult life can be fearful, but remember that you don’t have to face them all at once.

Apart from these, some teenagers worry about putting on weight or feel discomfort with how people treat them or feel their body doesn’t fit them. Remember that this fat is usually temporary.     4     If you feel stressful, find help from your teachers.

Besides parents, teachers and school medical staff, there are a number of other places where you can seek help.    5    Your doctor can provide support on body issues and you can insist on seeing the doctor alone if that makes it easier.

You are not alone in your feelings. There are ways to deal with many of the specific problems puberty can cause. The sooner you seek help, the sooner it will get better.

A．Get into the habit of focusing yourself.

B．You should know the source of your stress.

C．These feelings shouldn’t be a cause of worry.

D．You may feel miserable at the passing of childhood.

E．Exercise and healthy eating will help you get rid of it sooner.

F．You can turn to Childline at any time of the day or night.

G．Knowing your feelings better can make it easier to deal with them.

3 . Want to add a simple movement to your daily life? Walking may be your best choice.    1    .

Walking is good for your heart

Walking is considered as cardio（有氧的）exercise, no matter the speed at which you take it. Studies show that walking can reduce the risk of heart disease and lower your resting heart rate and blood pressure.    2    . You can go for a 30-minute walk once a day or break it up into three 10-minute parts.

    3    

What benefits physical health often benefits mental health-the same is true for walking. Just five minutes of walking can lower anxiety. If you have any kind of green space nearby, try to take advantage of it. One study showed that people who went on a 90-minute nature walk reported fewer bad feelings.

Walking can improve your sleep

    4    . Getting outside in the day for a walk can also help you stay awake in the morning and get sleepier toward the night. If a nighttime walk is your preference, experts suggest you finish it three hours before bedtime.

Walking can help with fat loss

Walking is a type of cardio workout that is good for fat loss and can help you achieve or keep a healthy weight. It should be done regularly and for long periods of time.    5    . A brisk（轻快的）pace refers to a 17-to 15-minute mile, or 50%to 70%of your maximum heart rate.

A．Walking can help reduce stress

B．That can help you sleep easily during the day

C．Here are some of the benefits walking offers you

D．Walking in the day can help you get a better night's rest

E．Good walking can also keep your head up and looking ahead

G．Walking at least 45 minutes a day at a brisk pace will see the most benefits

4 . E-cigarettes are increasingly being used as a nicotine (尼古丁) alternative (替代品) as smokers look for ways to kick their habit — and then stay off cigarettes for good. E-cigarettes work by heating a pure liquid called e-juice — made up of flavorings, propylene glycol, glycerin and often nicotine — until it changes into gas.

The use of vaping (电子烟) for tobacco stopping became especially popular in the UK after a study found that e-cigarettes helped 50,000 to 70,000 smokers in England give up smoking in 2017.

It is said that vaping cleared the 7,000 or more chemicals found in a burning cigarette and its smoke, many of which are harmful, according to Johns Hopkins medicine.

But their use has become controversial (有争议的) in the US and other countries because of warnings about possible long-term health effects, possibly from ingredients besides nicotine in the vape juice or cartridge. The US Surgeon General says vapes can contain “ultrafine substances that can be taken deep into the lungs, flavorants such as diacetyl, a chemical linked to serious lung disease, volatile organic compounds and heavy metals, such as nickel, tin, and lead.”

What's more, countless studies found teen use is a direct gateway to traditional cigarette smoking at a time when teenager use of e-cigarettes was increasing.

A 2019 outbreak of a mysterious vaping-related lung disease among American youth has triggered alarm as well. As of February 2020, the condition had killed at least 68 people and sickened more than 2,807, according to the US Centers for Disease Control and Prevention.

One 18-year-old American who vaped for over a year ended up in the hospital with “lungs like a 70-year-old.”

The condition, now known as EVALI (e-cigarette or vaping use-associated lung injury), is strongly linked to e-cigarettes containing vitamin E acetate, a sticky oil substance that can cling to lung tissue.

5 . Walking is the most popular aerobic physical activity in the United States, with 111 million people hitting the pavement in 2018 as part of their fitness goals. In addition, walking’s sister activity, hiking, attracted 57.8 million Americans to get out on the trails in 2020, a number that has increased notably since 2014.

Both tick the boxes for getting you moving outdoors, a low-risk activity in a pandemic. But are these two forms of exercise really that different from one another? And if so, which one is better for you?

Walking is generally an exercise that you do outside in an urban or suburban setting, or indoors in a gym on a track or treadmill. Hiking, in contrast, is walking that’s done in the outdoors and along natural terrain (地形). You’ll usually meet with elevation (高地) changes when hiking, but not necessarily when walking.

Both activities are low-influence cardiovascular exercises that can help you manage blood pressure and cholesterol levels. They are also great for your heart, said cardiologist Dr. Fahmi Farah, founder and medical director of Bentley Heart Medical Center in Fort Worth, Texas. “Walking is one of the best workouts for heart health for all ages, including those with heart problems and conditions,” she said. “Hiking is also heart-healthy and provides a higher calorie (卡路里) burn in a shorter amount of time.” Neither form of exercise is better than the other, according to Farah.

“Both are great at improving heart and lung performance, and both hiking and walking can help you lose weight,” said Darryl Higgins, a fitness expert and founder of Athlete Desk, a company that tests and reviews products such as treadmill and bicycle desks.

Which exercise is best for you depends upon your fitness goals and personal preferences. However, whether you go for a walk or a hike is good for you.

6 . How to boost your immune system

On the whole, your immune system does a remarkable job of defending you against disease-causing microorganisms.    1    Is it possible to fight the disease off? What if you improve your diet? Take certain vitamins or herbal preparations? Or make other lifestyle changes?

Now, researchers are exploring several factors, hoping to help you strengthen your immune system.

    2    Following general good-health guidelines is the single best step you can take toward naturally keeping your immune system working properly. Every part of your body, including your immune system, functions better when protected from environmental assaults and boosted by healthy-living strategies.

Like any fighting force, the immune system army marches on its stomach.    3    Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases.

Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of sicknesses, including stomach upset, and even heart disease, are linked to the effects of emotional stress.    4    

Regular exercise is one of the pillars of healthy living.    5    But does it help to boost your immune system naturally and keep it healthy? Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.

A．Your first line of defense is to choose a healthy lifestyle.

B．But sometimes it fails: A virus then invades and makes you sick.

C．Healthy immune system warriors need good, regular nourishment.

D．Scientists are actively studying the relationship between stress and immune function.

E．That doesn’t mean the effects of lifestyle on the immune system shouldn’t be studied.

F．It lowers blood pressure, helps control body weight, and protects against a variety of diseases.

G．Despite the difficulties in measuring the relationship of vitamins to immunity, scientists are making progress.

7 . Betty White, a longtime television star who enjoyed a second wave of popularity in her 90s, was best known for her roles on The Golden Girls and The Mary Tyler Moore Show.

Before Betty White’s death at the age of 99 on New Year’s Eve, she was regularly asked to reveal her secret to living a long, happy life. Her answers often came in the form of humor. In 2011, the Golden Girls actress appeared on the Late Show With David Letterman and shared her “Top 10 Tips for Living a Long and Healthy Life.”“Try not to die,” White said. “Avoid tweeting any photos of your private parts,” and “get eight hours of beauty sleep — nine if you’re ugly”. The following year White told The New York Times that she was a “health nut” whose “favorite food is hot dogs with French fries. And my exercise — I have a two-story house and a very bad memory, so I’m up and down those stairs.”

However, there were times when White gave some more serious understanding about how mental health was really important in staying healthy. “First of all, keep busy and don’t focus everything on you. That wears out pretty fast. It’s not hard to find things you’re interested in, but enjoy them and get involved in them. And I think that keeps you on your toes,” she told journalist Katie Couric on her 95th birthday.

White would have turned 100 on Jan. 17, 2022 and for a People profile that was meant to celebrate her centennial year, the actress spoke about how she was feeling. “I’m so lucky to be in such good health and feel so good at this age,” she said. “It’s amazing.”

8 . Truths About Protecting Your Eyes

Here, we identify five common myths ,and tell you how to truly keep your eyes healthy.

    1    

Eye exercise will not improve or preserve vision or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly changed with eye exercise.

Reading in dim light will worsen your vision.

Dim lighting will not damage your eyesight.    2    The best way to position a reading light is to have it shine directly onto the page, not over your shoulder. A desk lamp with an opaque (不透明度的) shade pointing directly at the reading material is the ideal.

Carrots are the best food for the eyes.

Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against some eye illness.     3    

It’s best not to wear glasses all the time. Taking a break from them allows your eyes to rest.

    4    Not wearing your glasses will strain your eyes and tire them out instead of resting them. However, it will not worsen your vision or lead to eye disease.

Staring at a computer screen all day is bad for the eyes.

Using a computer does not damage your eyes. However, people who stare at a computer screen for long periods tend not to blink as often as usual.    5    To help prevent eyestrain, adjust the lighting so it doesn’t create a glare or harsh reflection on the screen and rest your eyes briefly every 20 minutes.

A．Make a conscious effort to blink regularly.

B．However, it will tire your eyes out more quickly.

C．Doing eye exercise will delay the need for glasses.

D．This can cause the eyes to feel dry and uncomfortable.

E．If you need glasses for distance or reading, use them.

F．Just don’t expect them to prevent or correct basic vision problems.

G．But staring at a computer screen all day can contribute to tired eyes.

9 . Left foot, right foot, left foot, right foot… you can travel fast or slow. The movement of your feet gets you where you need to go. But it also gets you so much more!     1    

Walking helps you in various ways. First it makes your heart stronger. Studies show regular walking lowers your chance of heart disease. Walking for 30 minutes per day also helps control blood pressure. It can reduce your chance of having a stroke or developing some cancers, too.

Want to lose weight? You need to burn 600 more calories each day than you eat.     2    

Walking helps your brain health. As people age, their brains don’t work as well. One in 14 people over 65 years old suffers from memory loss. Older people who walk six miles or more per week keep their brains in better shape.     3     You don’t have to think about it, so you can consider other things. You can consider problems or think of ideas. You can think over conversations again or just remember funny things that have just happened recently.

Walking is also good for your wallet. It saves the cost of going to a gym.     4     A pedometer(计步器) can get you started. Begin with trying to take 1,000 steps in 10 minutes to set the right pace.

You can make walking part of your day. Instead of parking right next to your office, park a distance away— and walk. Do not take the elevator, but walk.     5     They are what they sound like. Rather than sit, you walk and talk things over.

Make walking a habit, and see how it makes you feel.

A．It is not easy to do that regularly.

B．Walking is the easiest way to do that.

C．You can even have walking meetings.

D．Putting one foot in front of the other isn’t difficult.

E．More walking and less driving help to make you healthy.

F．Walking quickly for 150 minutes each week to get a good workout.

G．Walking is a basic, simple exercise that’s suitable for almost everyone.
