I think the majority of people would agree that it's unhealthy to live in the past. After all, we're all familiar with the new age philosophy, “Yesterday is history, tomorrow is a mystery, but today is a gift{#blank#}1{#/blank#}Living in the past holds us back from being able to enjoy the present moment. But are there any benefits of revisiting a previous time? Actually, yes. The past has several advantages:

     Learning from our mistakes: We all know that poor choices can be some of life's greatest teachers{#blank#}2{#/blank#}

    {#blank#}3{#/blank#}By revisiting an unfavorable event from our past, we can often view it from a different perspective as time has passed. Being older and wiser, we are now able to reevaluate the experience and gain deeper insights and understandings of what happened and why, and how it has impacted us since. What once scarred us can now be healed through a newly-found awareness and no longer be a negative force in our lives.

    Motivated by earlier successes{#blank#}4{#/blank#}Other times life has been difficult. Remembering the past when we were at our best can help motivate us out of our current slump(低谷) and put us back on track for success. Use your past successes to propel(推动) you on to newer and greater things.

    While it's evident that revisiting the past has several advantages, there is a warning. Just like an amusement park, it's fine to visit but you cannot stay there forever. At some point, the park closes and all visitors are asked to leave. Enjoy the past when necessary but don't always stay there. Use it for living in the present and planning for the future{#blank#}5{#/blank#}

A. Moving beyond

B. That's why it's called the present

C. In that way, it will serve you well

D. See the mistakes as a step on the road to a solution

E. There are times when we have all enjoyed success on a variety of levels

F. Recalling times when we made mistakes can help us make better future decisions

G. So, failure is the mother of success

Making the Most of Life Experiences.

    If you ask anyone what the purpose of life is, you'll likely receive wildly different responses. The answer to this question is deeply personal because different things are important to us throughout the course of our lives.{#blank#}1{#/blank#}

    Finding ways to make the most of our experiences is a challenge we face every day. Here are some ways to make your experiences meaningful.

    Follow your dreams.

    The number one way to live a life free of regret is to follow your dreams. Passion will die without actions supporting them.{#blank#}2{#/blank#}Every day take an action, no matter how small, to achieve your goals. Each day is a step forward and none of it is wasted.

    Make lots of mistakes.

    {#blank#}3{#/blank#}Many of my strongest memories come from the times I've failed，and those lessons have stayed with me. Failure is beneficial to us. And time allows me to see the value of even the most painful situation.

    {#blank#}4{#/blank#}

    Difficult and painful experiences shape our character but can also weigh us down. These prevent us from moving forward. So much of our progress in life relies on willpower and a healthy emotional stale. If you're under stress, your body and mind both require time to recover.{#blank#}5{#/blank#}

    For me, life is about experiences. We all have to dream, work hard, and fail before we can achieve success. Maybe we'll discover along the way that the journey is more important than the destination.

A. Take care of yourself.

B. Improve your personality.

C. Making mistakes is the surest path to grow as a person.

D. It's best to rest, recover, and slowly build back up your strength.

E. Yet one thing stays with us no matter where we go: our experiences.

F. Though we try our best to make fewer mistakes, it is impossible to avoid them.

G. Though we can't choose the outcome of our actions, we can choose to keep pursuing(追求).

    Every day can be a fresh, new beginning—this is very important if you had a difficult day before. By starting with some preparations, you can face the problems of the day in a good mood(心情). {#blank#}1{#/blank#}

    Exercise. Exercising is one of the best methods to start your day for your mind as well as the body. {#blank#}2{#/blank#} In addition, it also reduces stress and improves your metabolism(新陈代谢). So go for a walk, go for a bike ride, or go to the gym in the morning.

    Organize yourself. {#blank#}3{#/blank#}Make a to-do list and try to follow it. It will keep you organized(有条理的) and make your day easier. However, make sure that your to-do list is manageable. There are only so many things you can do in a day.

    Smile. Starting your day by acting the way you want to feel can help you be in a good mood.{#blank#}4{#/blank#}The easiest thing to do is smile. Just smile because you are alive and you can. Watch or listen to something humorous so you can laugh. It makes you feel positive and really good about yourself and the world that surrounds you.

    Keep important items in the same place. To make mornings less busy, start a habit keeping your important items in a place easy to reach.{#blank#}5{#/blank#}This way, you are never looking for that lost item when you are running behind.

A. Write down the tasks for the day.

B. Try other actions to get yourself to feel happier.

C. Try some of the following tips to start your day right.

D. Put your keys, wallet, purse, and other important items there.

E. Instead of rushing through the rooming, go slow and take your time.

F. It increases brain's working speed, which can help you get a jump-start on the day.
G. If you feel angry or tired, do something physical to make yourself feel happy.

    Next time your plane lands, listen to the sound of the tyres hitting the ground. {#blank#}1{#/blank#} The tyres of cars, motorbikes and trucks are also often made of the same stuff.

    {#blank#}2{#/blank#}Workers cut the trunks of the trees and collect a white liquid called latex（乳胶）. In the nineteenth and early twentieth centuries, huge numbers of rubber trees were planted in countries including Malaysia, Burma and Brazil. Nearly half the rubber which is produced each year is natural rubber and there is always a need for more.

    Rubber trees are not easy to grow. {#blank#}3{#/blank#} Some trees survive while others die and it is all decided by their genes. British scientists have been working together to look at rubber trees. They have now discovered the "genome" (基因组) of the rubber tree. {#blank#}4{#/blank#} The genome contains all the information the plant or animal needs to grow. The genome for a plant such as a rubber tree is smaller than a human genome but it is still very long, which is why it has been so difficult to find. Scientists say the work has been like putting a picture puzzle together where all the pieces show blue sea and blue sky.

    Now scientists can use the rubber tree genome to produce stronger trees. By understanding the genome, they can change the DNA in rubber trees in useful ways. {#blank#}5{#/blank#}

A. Natural rubber comes from trees.

B. Regretfully, many forests are being severely destroyed.

C. This is the way genes fit together in very long chains of DNA

D. Stronger trees have played a more important role in producing tyres.

E. They are affected by changes in temperature, rainfalls, winds and diseases.

F. The reason why the tyres don't explode is that they are made of natural rubber.
G. In the future, it will be possible to grow trees which survive climate change and disease.

When you think about art, you might consider it to be permanent. After all, that picture you drew in kindergarten might still hang on your refrigerator years later. {#blank#}1{#/blank#} Think about a Broadway performance. When it's over, it's over. Sure, it might live in your memory. But the live show is a special event. It is limited to a certain time and place. 

Can you think of other forms of art that are temporary? If you're a fan of the beach, sandcastles might come to your mind. Have you ever spent hours building a beautiful sandcastle? {#blank#}2{#/blank#} You knew your work of art would be gone as soon as the tide came in. The sandy beach is a canvas where nature erases "paintings" daily. 

Most of the time, art made from sand can't last long. Still, many people love using sand to create their own unique vision of beauty. One of the most attractive types of sand art is sand animation. {#blank#}3{#/blank#} Artists who work in sand animation use sand to make a set of images that usually tell a story. They often start with a large amount of sand on a flat surface, such as a table. They then use their hands and fingers to draw in the sand. 

{#blank#}4{#/blank#} However, the wide variety of beautiful and highly-detailed sand artworks might surprise you. Many of these works or art are temporary. That's where the animation part comes in. 

Sand animation artists create a series of images that move to tell a story. They might also use music and special lighting to complete the effect. Sometimes they photograph or video their creation throughout the process. {#blank#}5{#/blank#}.

A. It is a type of live performance art. 

B. Not all works of art are permanent, though. 

C. Sand animation is beautiful but lasts only for the moment. 

D. Then, they turn it into a sand animation movie when it's finished. 

E. It might seem like using sand would limit the art you could make. 

F. If you have, you would probably be sad when it was time to leave the beach. 

G. Building a sand castle is a family-friendly activity perfect for large groups.
