    Bill always does everything very carefully．Everyday he drives his car to go to work and go home．He drives his car slowly and never has an accident．He often says that travelling by car is much safer than travelling by plane．

    Today，he has to go to another city to have a meeting．The meeting will begin at nine o'clock．And it is eight now．If Bill goes there by train or by car, he will be late for the meeting．Bill has no idea．One of his friends，John，says to him，"Don't worry, Bill．I can take you there in my own small plane．And we can get there at half past eight．"Bill is afraid of going there by plane．John tells him that it is very safe．Bill gets on the plane at last．

    John starts the plane and begins taking off．Bill is too afraid，so he closes his eyes．After a minute or two，he opens them again，looking out of the window of the plane，and says to John，"Look at those people down there，they look as small as ants." "But they are ants." says John．"Don't you know we are still on the ground?"

Einstein has to speak at an important science meeting.  On the way there, he tells his driver that looksa bit like him, "I'm sick of all these meetings. I always say the same thingsover and over!"

The driver agrees, "You're right. As your driver, I attendall of them, and even though I don't know anything about science, I could give thespeech in your place. "

"That's a great idea!" says Einstein. "Let's exchangeour places then!"

So they exchange clothes. As soon as they arrive, the driverdressed as Einstein goes on stage and starts giving the usual speech, while thereal Einstein, dressed as the car driver, attends it.

But in the crowd, there is one scientist who wants to show offand thinks of a very difficult question to ask Einstein, hoping he won't be ableto answer. So this guy stands up and cuts in the speech by raising his very difficultquestion. The whole room goes silent, holding their breath, waiting for the answer.

The driver looks at him, dead in the eye, and says, "Sir,your question is so easy that I'm going to let my driver answer it for me."

"Jobie Nymble from Class 3 Grade 9 wins the first prize in the girls' 100-meter hurdles!" crowd cheered.

"Next is the city match. Here we come!" Jobie said to her green training shoes. They looked of dirty but she didn't care. They were her lucky shoes and she treasured them. She expected to take the gold next Saturday with the shoes on. Jobie trained with excitement all week long. At track practice, she jumped over those hurdles faster than she'd ever done before.

The day before the match was her teammate Marisol's birthday at Hidden Park. Jobie put on favorite clothes and her lucky training shoes. The birthday party was crowded and there she saw the BIGGES Tslide (滑梯) she had ever seen. Without thinking twice, Jobie took off her shoes and ran toward the slide. She tried the slide again and again. When it was finally time to go home, she went back to the place where she'd left her shoes. As she eyed the area from a distance, a sense of dread set in. The closer she got, the faster her heart beat. When she reached the place, her heart stopped. Her lucky shoes disappeared. Jobie's teammates helped her search the park. No lucky shoes. "Goodbye, gold," Jobie cried.

The next day, the best teams got together at Hidden Park. Soon it was time for girls' 100-meter hurdles. Jobie's teammates cheered her up as she slowly walked to the starting line, her feet getting wet in her new shoes.

Runners were ready now. Jobie had just raised her eyes and something familiar on the bleacher (看台) caught her eyes. Her shoes! Someone must have found them and put them there.

In a flash, Jobie was off. She set fully focus on her lucky shoes as she cleared hurdle after hurdle. Closer and closer she got. Just one more hurdle and— "Number 52, Jobie Nymble, takes the gold for Riverside School," said the speaker.

Jobie picked up her lucky shoes and rushed to her teammates. Marisol cried out, "Jobie, you broke a record for the hurdles!" Then she added, "Lucky you."

"Lucky me?" Jobie questioned at first. Then, after a minute, she looked down at her feet and smiled. No lucky shoes. Smiling with joy, Jobie said to herself, "Lucky Me."

Sometimes a common job can make a difference. A man has been working hard at Peking University for 17 years，repairing（修理）almost 500 bikes. 

Lin Qinggang，from Xingtai，Hebei Province，he worked as a builder and sold bikes in Beijing. Then in 2017，Peking University built a small repair shop for Lin. 

In the past years，Lin's great services have won the hearts of teachers and students at Peking University. He always gets to his repair shop as early as he can. "If people come to take away their bikes and I'm not there，they will have to wait"

Students usually come over to Lin's shop to have their bikes repaired before and after lunch，so he is often busy during these hours and he has to finish his meals quickly. "I can____ have lunch on time，and usually have dinner at about 8 or 9 pm，and sometimes even at 10 pm"

"Some of my services were free，but the students still gave me money or paid more. They encouraged me to work harder，Lin said. 

Not everyone is born to be a great person. However，each of us might live a meaningful life like Lin.
