    Garbage or trash is a major kind of environmental pollution.Each person produces about 2kg of trash a day.We are making waste products faster than nature can break them down.And we are using up resources（资源）faster than they can be replaced（取代）.

    This adds up to trouble for the environment.Where does all that garbage go?What can be done to help dispose of（处理）garbage?How call we make less garbage?

    Garbage isn't just the smelly rotting fruits,vegetables or meat that we throw away in our homes.Those are only a small pan of all the stuff we throw away.We create other kinds of waste,in construction,mining and in our factories.

    Did you ever wonder what happens to your garbage?Most is burned or buried in landfills（垃圾填埋场）Less than a quarter of our waste is recycled.

    With a population of 1.3 billion（十亿）,garbage is a big problem for China.Chinese cities create around 148 million tons of garbage every year.The amount is growing at around 10 percent each year.

    Once we used about 3 billion plastic shopping bags every day in China.The result was a great waste of resources and serious pollution.So we did something about that.Now we use more cloth bags and shopping baskets when we shop.

    In the coming years China will build waste-to-energy plants in cities to clean up the garbage.But there's a lot more that needs to be done.And you can play a part.

    There are so many expressions in American English that sound pleasant but are not.

    “Face the music” is a good example. When someone says they have to face the music, it does not mean they are going to a musical performance or concert. To face the music means to accept the unpleasant results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, “Thanks so much for watching my car while I'm away. But please do not drive it. It is an extremely fast car.” But you do not listen. You want to show off and pretend the car is yours. So, you drive it around town. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is serious. When your friend returns, you must tell her what you have done and “face the music”. That could mean losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as “face the music”.

    To “take your medicine” means to accept the results from something bad you have done. And if someone says, “You made your bed. Now lie in it.” He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    “Pay the piper” also means the same as “face the music”. But, that expression has its own very interesting beginning. We will talk about that on another Words and Their Stories.

    You may probably meet most of the powerful graduation speakers, here who are well-known people in their fields. I think the schools couldn't have picked better speakers than them, because they set good examples, deeply inspiring us in our daily life.

    1) Steve Jobs, Stanford University:

    "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your time is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice... "

    2) Oprah Winfrey, Stanford University:

    "I consider the world, this Earth, to be like a school... And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility... "

    3) Bono, University of Pennsylvania:

    "For four years you've been buying, trading, and selling everything you've got in this market-place of ideas. Your pockets are full, even if your parents' are empty, and now you've got to figure out what to spend it on... The world is more flexible than you think and it's waiting for you to hammer it into shape... "

    4) Michael Dell, University of Texas at Austin:

    "Now it's time for you to move on to what's next and obtain your desire. But you must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures and obstacles. But you will learn from your mistakes and the mistakes of others."

When it comes to lowering blood pressure,studies have typically shown that aerobic(有氧的)exercises are best. Recent research suggests another type of physical activity is worth including as an effective tool to prevent and treat high blood pressure.

Exercises that engage muscles without movement,such as wall squats and planks,may be best for lowering blood pressure,according to a large study published in July,2023 in the British Journal of Sports Medicine.

This type of training is known as isometric exercise,according to the Mayo Clinic.Isometric muscle action happens when muscles contract but do not visibly change length,and the joints involved don't move,facilitating stability of the body.Isometric exercises can be done with weights or without,just relying on the body's own weight.

"These findings provide a comprehensive data-driven framework to support the development of new exercise guideline recommendations for the prevention and treatment of high blood pressure,"said study coauthor Dr.Jamie O'Driscoll in a news release.  The researchers looked into randomized controlled trials that had reported the effects of exercise interventions, lasting two or more weeks,on blood pressure between 1990 and February 2023.From a review of 270 trials with 15,827 participants,the researchers  found that  among HIIT  (high  intensity interval training),isometric  exercise, aerobic exercise,dynamic resistance training and a combination of the latter two,isometric exercise led to the greatest reductions in blood pressure.

It's also important to note that there are other lifestyle changes as well as exercise that can benefit your blood pressure.These include keeping to a healthy weight,eating a balanced diet,cutting down on salt,not drinking too much alcohol and ensuring that you continue to take any prescribed medication.

More research is needed to determine exactly why isometric exercises might be better for lowering blood pressure than other types of training,the authors said.

Human bodies were actually designed for walking,a wonderful form of exercise at no cost.It's kind to our bodies and great for our waistlines. {#blank#}1{#/blank#}

Probably you already love to walk,but you're getting bored of tracing the same old route day after day,or maybe you're new to walking and aren't sure how to get started.{#blank#}2{#/blank#} Ask yourself,what do you want to get out of walking aside from the health benefits?Do you want to meet other people?See new places?Get out into the countryside or explore a new city?Knowing your goals will help you decide on the type of walk you want to do.

Call up your friends and schedule walks with them if socializing is your aim. {#blank#}3{#/blank#} Many malls have groups that come every day,or every weekend,to "walk the mall".These groups are always happy to include one more walker! 

{#blank#}4{#/blank#} Many large cities have incredible gardens and parks that include quiet walking trails getting you off the beaten path.Thanks to the Rails to Trails program,railways across the country are being transformed into scenic walking paths that are a perfect way to seek calmness.

From the benefits to your heart to your overall happiness,walking is just plain good for you.{#blank#}5{#/blank#} It's a fantastic way to get to know a place by the power of your own two feet.

A.This month,pick up a map and start walking.

D.Either way,it's time to accept the idea of walking with a purpose.

E.Recently,science has proved that walking is good for your body shape.

F.And best of all,it's a great way to see new things and meet new people!
