The crowd at the airport rushed forward. The passengers had been waiting for a couple of hours for an airport worker to open the door leading to the plane outside. No one was in a good mood. An old man got stuck in the middle of the rush, He fell down and his head hit the hard floor. B1ood came out of his head. He appeared to be unconscious. Everyone rushed past him, except for Dana. She called for help.

 A minute later, a young airport worker showed up. Hardly looking at the old man, she told Dana to get on her plane. She said the old man would be okay, and walked away.

 Dana cried for help. Another airport worker appeared. He told Dana to get on the plane. Dana said that she was not moving until an ambulance(救护车) arrived. The worker said her plane would leave without her. Dana said that she didn't care.

 An ambulance with a doctor and a nurse finally arrived. They put him into the ambulance and drove off.

On her way out to the plane, which was still refueling(加油), Dana saw the worker who didn't care about the old man at the very beginning. The worker said, “You're lucky the plane didn't leave without you.”

 “The plane?” Dana asked.“Who cares about the plane? How could you be so cold? That was an old man; he could have been your grandfather! How would you like it if everyone just stepped over your grandfather and went on their way?”

    A long time ago, a king put a huge rock in the middle of a roadway, and then he hid (藏) himself to watch because he wanted to know who would move the huge rock out of the roadway.  Some of the richest people came by and simply walked around it. Many of them loudly blamed (谴责) the king for not keeping the road clean, but none did anything to get the rock out of the way.

    Then a farmer came along carrying a heavy bag of vegetables. Upon walking close to the rock, the farmer put down his heavy bag and tried to move the rock to the side of the road. After much pushing, he finally succeeded. After the farmer picked up his bag of vegetables, he noticed a purse lying on the road where the rock had been. The purse included many gold coins and a note from the king saying that the gold was for the person who moved the rock away from the roadway.

    The farmer learnt what many of us never know! Every obstacle (障碍) means an opportunity to improve our condition.

Dear Li Na,

    I'm really glad to receive your e-mail. You said you were learning to cook. Is it interesting? I think if you want to keep healthy, food is very important. You'll be better if you try all kinds of food, especially（特别是） vegetables and fruit. I eat them every day.

    You asked me how to make a milk shake. There are different kinds of milk shakes, such as apple milk shake, banana milk shake, carrot milk shake and watermelon milk shake. Apple milk shake is my favorite, because apples and milk are both good for our health. Before starting, we need an apple, a cup of milk, some ice-cream and two spoons of honey. Of course, you need a blender.

    Now, let's start. First, peel an apple and cut it up. Next, put the apple, the milk, some ice-cream and two spoons of honey into the blender. Then turn on the blender. Keep it going for only one minute. Finally, pour the apple milk shake into a glass and drink it. It's delicious!

    I want to learn how to make some Chinese food, such as dumplings, noodles and zongzi. Could you teach me?

    Write soon!

Yours,

Maria
