We are often warned by our teacher not to waste precious (宝贵的)time, because time lost will never return. I think it quite true. What does time look like?  {#blank#}1{#/blank#}. Time is abstract (抽象的), so we have to think about it.

Time passes very quickly. {#blank#}2{#/blank#}.  It is because they don't know how to make use of their time. They waste it in going to theatres, cinemas and parks, and doing other things. Why do we study every day? Why do we work? Why do most people would rather take buses instead of walking? The answer is very simple. {#blank#}3{#/blank#}.

Today we are living in the 21st century. {#blank#}4{#/blank#}. When a person dies, his life ends. Since life is short, we must devote our time and energy to our study so that we may be able to serve the people well in the future. {#blank#}5{#/blank#}, for it does not only bring us failure but also does us other harm. If it is necessary for us to do our work today, let us do it today and not leave it until tomorrow.

Remember time is much more valuable (珍贵的)than money.

A. We look upon time as life

B. Nobody knows because we can't see it or touch it and we can't buy it with money

C. Some students say they don't have enough time to review all their lessons

D. Laziness is the thief of time

E. We wish to save time because time is precious

I am a book lover. So my house is forever full of 1. I have new ones, old ones, hard covers, paperbacks, 2and non-stories. I have three boxes of books in my closet, two boxes of books on the floor of my bedroom, and a box of children's books 3 for my future grandchildren. I have even more books 4the two I wrote on my desk. I try to keep the books 5 building up by donating as many as I can to the local 6, but as soon as I donate a few, I find myself buying a few more.

    Books I read keep my mind young, and my heart 7, and soul bright. They bring me knowledge, laughter, and joy. They connect me with the wisdom of the past and the new ideas of the 8. They keep me moving on the right path as a journey through life.

    I have learned that people are a lot like books as well. Some have bright and shiny covers 9  don't have very much to say inside of them. Others look old and plain but so full of 10and light that reading them can 11your whole life. One difference between books and people, though, is that while a book has an ending, the writing inside of us 12forever.

Take care when writing the book of your own life. Fill it with love for yourself, others and this world. Fill it with all the wisdom you have learned, goodness you have done, 13you have shared, and joy you have 14. Keep writing it every day, too. Make it everything you are and everything you want to be, and then15it to everyone. I know it will be a wonderful and fantastic book.

David was a truck driver. Recently he was thought to be a great man.

Last Monday, he was driving along the road with his son and his friend. Suddenly he saw a car hit another truck (卡车) and catch fire. The accident was just in front of his truck. Without thinking, he stopped his truck, found a fire extinguish er (灭火器) and ran towards the broken car. But other car drivers still sat in their cars. David began to fight the fire. His action encouraged his friend. He also came and gave David a hand. Later, David's son and four other men came to help. Another five men pulled the car driver and her granddaughter, a three-year-old girl, out of the car successfully. They were all safe except that the driver's leg was hurt.

When people talked about David's brave action, David said, " I didn't think too much then. I just did what other people would do in that situation. When I first got out of the truck,I wished they wouldn't be dead. When I saw they were alive, it was really great!"

One day, a successful businessman was getting ready to go to his office in the morning. When he opened the door of his car, a stray dog(流浪狗) sleeping under his car suddenly came out and bit his leg! He was angry and threw a rock at the dog, but he was not able to hit it. 

Upon reaching his office, the businessman called a meeting of his managers. During the meeting, he took out his anger on his managers. His managers were upset about this, and took out their own anger on the employees(员工) working under them. Gradually, the businessman's anger spread through the whole company. '

The businessman was still angry after returning home. His wife opened the door. She asked him, "Why are you so late today?" The man shouted at his wife, "I didn't go to the office to play soccer, I went to work. So don't ask me such stupid questions!" His wife was upset about being shouted at for no reason. She turned her anger on their son, who was watching TV. "This is all you do. You have no interest in studying! Turn off the TV now!" She yelled. 

The son became upset as well. He walked out of his house and saw a dog passing by. He picked up a rock and threw it at the dog angrily. The dog ran away, barking in pain. 

Sometimes, when we are angry about something, we might take out our anger on others who are not to blame for our mood. This is not fair to others. We should learn to control our anger. 

① Do you have a dog? What can your dog do for you? Do you know that dogs can read our feelings? Now some people find that dogs can smell (v.闻到; n.嗅觉) people's stress (压力).

②Dogs really are man's best friends. They have special smell. A new study said that dogs can smell if people are feeling stressed. Teachers at Queen's University, UK, made the study. They got breath(呼吸)and sweat(汗) from people both before and after doing a hard maths problem. They looked at the people's heart rate (心率), blood pressure (血压) and stress feeling in the study. Dogs can smell the difference in breath and sweat from people. Then they can know when people are stressed.

③The finding is wonderful: the dogs found stress in 675 of the 720 people. It could be 93.75% right! Australian News reported. The study's writer Clara Wilson said, "stress can change people's breath and sweat. Dogs are very good at smelling these changes." In the study, she also said, "this finding helps us learn that how dogs may know people's feelings."

④ This finding shows how special the bond is between people and dogs. The finding also tells us that dogs are very clever. And maybe dogs can help stressed people.
