A major source of teen stress is school exams, and test anxiety is not uncommon. When you recognize your teen is under stress, how can parents help your teen stay calm before an exam? Be involved. Parents need to be involved in their teen's work. {#blank#}1{#/blank#} What they look for is your presence — to talk, to cry, or simply to sit with them quietly. Communicate openly with your teen. Encourage your teen to express her worries and fears, but don't let them focus on those fears.

    Provide a calm setting. Help your teen set up a quiet place to study and protect his privacy. Give them a nutritious diet. It is important for your teen to eat a healthy, balanced diet during exam times to focus and do her best. {#blank#}3{#/blank#} If this happens, encourage your teen to eat light meals or sandwiches. A healthy diet, rather than junk food, is best for reducing stress.        

    {#blank#}4{#/blank#} Persuade y our teenager to get some sleep or do something active when she needs a real break from studying. Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance her time so that she will feel comfortable taking time out from studying to spend time with friends or rest.       

    Show a positive attitude. {#blank#}5{#/blank#}Your panic, anxiety and blame contribute to your teen's pressure. Make your teen feel accepted and valued for her efforts. Most importantly, reassure your teen that things will be all right, no matter what the results are.       

A. A parent's attitude will dictate their teen's emotions.     

B. Exam stress can make some teens lose their appetite.     

C. They will only make the situation worse.       

D. Encourage your teen to relax.       

E. The best thing is simply to listen.       

F. Help your teen think about what she has to study and plan accordingly.    

G. Your teen may also make negative comments about themselves      

    Thinking about a career in public safety or law enforcement? Statistics show that these careers are growing, have great benefits, and can be very rewarding. {#blank#}1{#/blank#} But there are hundreds of public safety jobs to think about-everything from police officer who protect people to driver's license examiners who test driving skills.

    For example,Angela Bloom is an animal control worker for the city.She and her co-workers pick up animals that are lost, sick, or dangerous. {#blank#}2{#/blank#}For this job, being in good physical condition is important and a high school diploma is required.It may be necessary for candidates to have received on-the-job training and hold certification.

    {#blank#}3{#/blank#}He looks for health problems in places where people prepare and serve food.There are many kinds of jobs for inspectors.For example,public safety inspectors look for safety violations or dangerous workplaces and fire inspectors look for problems in buildings that could cause fires. {#blank#}4{#/blank#}A college degree is often necessary. Actually, applicants with a bachelor's or master's degree,related experience or training in a foreign language may have the best job prospects.

    {#blank#}5{#/blank#}For those interested in working in this dynamic and rewarding field,a wide variety of options are available.So remember,if you like working with the public,and are looking for a good job,a career in public safety might be perfect for you.

    Below is some advice on how to prevent cancer:

    Eat blueberries

    Aside from being a healthy and delicious snack, the blueberries contains pterostilbene, which has important colon(结肠) cancer-fighting. {#blank#}1{#/blank#}. Blueberries also offer a large dose of vitamins C. So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.

    Relax

    {#blank#}2{#/blank#}? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer.{#blank#}3{#/blank#}!

    Break a Sweat

    {#blank#}4{#/blank#}. In a study of 29,110 men published in The International Journal of Cancer, men who exercised just once a week had a percent lower risk of prostate cancer than men who didn't work out at all. The better the frequency and intensity of the exercise, the bigger the reduction in risk, according to the study.

    {#blank#}5{#/blank#}

    There's no question that secondhand smoke kills, A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物）in their body than nonsmokers working in smoke-free locations. What's worse, their levels of the carcinogen rose 6 percent for every working hour. Many states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.

    Taking good notes is a time-saving skill that will help you to become a better student in several ways. {#blank#}1{#/blank#} Second, your notes are excellent materials to refer to when you are studying for a test. Third, note-taking offers variety to your study time and helps you to hold your interest.

    You will want to take notes during classroom discussions and while reading a textbook or doing research for a report.{#blank#}2{#/blank#} Whenever or however you take notes, keep in mind that note-taking is a selective(选择的) process. That means you must first decide what is important enough to include in your notes.

    {#blank#}3{#/blank#}

    Read the text quickly to find the main facts and ideas in it.

    Carefully read the text and watch for words that can show main points and supporting facts.

    Write your notes in your own words.

    {#blank#}4{#/blank#}

    Note any questions or ideas you may have about what was said or written.

    As you take notes, you may want to use your own shorthand(速记). When you do, be sure that you understand your symbols and that you use them all the time.{#blank#}5{#/blank#}

A. Use words, not complete sentences.

B. There are three practical note-taking methods.

C. You must write your notes on separate paper.

D. Otherwise, you may not be able to read your notes later.

E. You will also want to develop your own method for taking notes.

F. The following methods may work best for you.

G. First, the simple act of writing something down makes it easier for you to understand and remember it.

    Many students have trouble staying focused in class. Some of them easily become absent-minded or fall asleep. As a result, they turn to study drugs in order to stay focused in school. {#blank#}1{#/blank#}

    Get some sleep.

    {#blank#}2{#/blank#} And it is important to stick with it. Having irregular sleep cycles can really affect concentration and physical well-being. Try to go to sleep at the same time every night and get eight to nine hours of sleep. Your body will thank you in the morning.

    {#blank#}3{#/blank#}

    Eating first thing in the morning provides fresh energy throughout the day, and it doesn't even have to be a big meal. Something as small as a bowl of oatmeal can make students more energetic and efficient for the rest of the day. And foods like peanut butter, berries, and whole grains have even shown to improve memory.

    Turn off your phone.

    An obvious way to maintain concentration is to avoid distractions that take your attention away.

    {#blank#}4{#/blank#} When students need to channel their energy into studies, turning off the phone or even putting it on airplane mode is a good way to centralize their drive and keep distractions at bay.

    Break a sweat.

    Trying to concentrate in class will feel as challenging as a marathon if you're not in good physical health. On the other hand, actually running a marathon may help boost your ability to concentrate, as exercise is shown to have many benefits for the brain. While you don't necessarily have to run 26 miles before class or work, doing exercise in the morning can get your blood flowing towards your brain. {#blank#}5{#/blank#}

A. Do not skip breakfast.

B. Sit in the front if you sleep in class.

C. That helps in strengthening the mind.

D. Probably the biggest one is the smart phone.

E. Students should have a regular bedtime routine.

F. But many study drugs have proven harmful to human health.

G. However, there are other all-natural ways to help with concentration in class.

As the world struggles to deal with the climate crisis, some companies are working to remove polluting carbon dioxide (CO₂) from the air. {#blank#}1{#/blank#}, but two US companies have recently made important progress.

Scientists say large amounts of CO₂ must be removed from the atmosphere and stored. {#blank#}2{#/blank#}. But there's so much CO₂ in the atmosphere that just planting trees and protecting forests won't solve the problem. In addition, when plants and trees die, the carbon they've stored gets released again.

That means humans need to come up with ways of removing carbon from the air and storing it. This is called Direct Air Capture (DAC). The science of removing carbon from the air is challenging, and it's still pretty new. Most DAC processes require a large amount of energy, {#blank#}3{#/blank#}.

A company called Heirloom has just opened the first DAC plant in the United States. The company heats up the limestone (石灰岩)to separate out the CO₂, which is then locked away in concrete (混凝土). The process is extremely expensive. {#blank#}4{#/blank#}. That's a tiny amount compared to how much carbon needs to be removed from the atmosphere, but the company says it hopes to remove a billion tons per year by 2035.

{#blank#}5{#/blank#}. Some people worry that it will take too long for DAC technology to become powerful enough to make a difference. Others worry that focusing on removing carbon could take attention away from more important climate actions, like switching from fossil fuel s to renewable energy. But experts say the decision isn't to do one or the other. The world needs to end fossil fuel use and pull carbon out of the air.

A. It's a huge and challenging goal

B. Plants and trees can do this naturally

C. Everyone is not excited about carbon removal

D. The new plant can remove 1,000 tons of CO₂ year

E. Graphyte is another US company working on DAC

F. and CO₂ is just a small part of the gasses that make up air

G. so one puzzle for these companies is how to remove carbon without creating more pollution
