Last weekend at the airport, I had some extra time before going through security to catch my flight. While wondering what to do, I decided it was the perfect time and place to look for an act of kindness to do.
Outside security there was a girl having flowers for sale. I told her that Td like to buy flowers for someone else, and she could decide who to give them to. She looked a little confused, so I suggested perhaps she should give them to someone who looked a little sad. That was because he or she might need some cheering up.
At first, the girl answered, "That's crazy." But then I explained a little more about the idea of doing something kind' for a stranger, and she understood.
"I'll never know how it 'turns out头" I said. "But you will have the opportunity to make someone have a good day." At the time, she started to seem excited about it.
She .went to take the flowers out of the water they were sitting in, and I explained," It's fine to leave them there until the person you want to cheer up comes."
At that point, I think she was between surprised and happy, because it might be her first time to meet a customer like me. I paid for the flowers, said goodbye, and joined in the security line. What a nice day I had!
When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry (= unclear). Many people who do a lot of work, such as writing, reading and sewing become near-sighted.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background and other things around it has changed. The difference between these two different eve views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
What is life's greatest gift? It is choice. Choice is the ability to choose some actions from a set of things to achieve a goal. The reason is that it turns us from dumb animals into artists. Choice becomes the tool we use to sculpt our life. The tool doesn't come free，however，for the price of choice is responsibility. It is enjoyment.
Choice is power. Choice is at the heart of life. It's the creative power of life. Life is always changing and we have to make lots of choices. We often need to check where we are on our journey. We need to ask questions: Am I moving closer to my goal? If not, what action will I take now to make myself realize my goals?
And our life becomes more convenient or comfortable because of them. For example，you decide which stores to shop at and which bus station to go to. But the decisions that we make to sculpt our life are much more important than deciding where to shop. The more we understand the difference between small and big decisions，the more pleasure we will get.
Life is like a chess game. All chess lovers realize that it isn't necessary to win to enjoy the game. Make the best moves you can under the conditions. Then you can enjoy your life.

But sometimes she would say, "You are not4enough to understand that, my son. When you are ten years old, you may ask me about it, and I will tell you."
The first time Frank saw an hourglass, he was very much interested, but he did not know5it was. His mother said, "An hourglass is made in the6of the figure 8. The sand is put in at one end, and runs through a small hole in the7. As much sand is put into the glass as will run through in an hour."
When Frank watched the little stream of sand, he was impatient.8it would not run faster. "Let me9it, mother," said Frank. "It is lazy, and will never get through." "Oh yes, it will, my son, "said his mother. "The sand moves down little by little, but it moves all the time." "When you look at the10of the clock, you think they go very slowly. and so they do; but they never11.""While you are playing, the sand is running, grain by grain. The hands of the clock are moving, second by second. At night, the sand in the hourglass has run through twelve times. The hour hand of the clock has moved all around its face. This is because they keep working every12. They do not stop to think how much they have to do, or how long it will13them dodo it."
Now Frank's mother wanted him to learn a little poem, but he said, "Mother, I can14do it." His mother said, "Study all the time. Never stop to ask how long it will take to learn it. You will be able to say it very soon." Frank15his mother's advice. He studied line after line, very busily and in one hour and a half he knew the poem perfectly.
