Why do you think people who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there some connection between spices and healthy food?

Researchers from Cornell University think that it is because spice plants have some important chemicals(化学物质)．These chemicals can kill bacteria(细菌)which spoil food．

“Most common spices can kill 75 to 100 percent of the bacteria in food，”explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates，

Do you like your food spicy? Your answer probably tells something about the country you come from．If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food taste good．

An old man was fishing on the bank of a river. A child came to see him fishing. The old man was really good at fishing and it didn't take long for him to catch a full basket of fish. The old man saw that the child was very cute, and he wanted to give her a whole basket of fish. But the child shook her head. The old man was surprised and asked, "Why don't you want the fish? '
The child replied," I want the fishing rod(竿)in your hands. "
The old man asked," Why do you want the rod?"
"It doesn't take long to eat all the fish in a basket. But if I have the fishing rod, I can go fishing by myself and I won't be afraid of not having any more fish to eat.
I think you will certainly say that the child is very smart. Wrong! If she doesn't know how to fish, she cannot have fish to eat, even though she has the fishing rod. It's useless to only have a fishing rod. Fishing skills are the most important, not the fishing rod.
Too many people think that if they have a "fishing rod" in their life, they will no longer fear the wind and rain. They are just like the child, who thought that if she had a fishing rod, she would have fish to eat.

A group of swans flew down to a beach where a crow (乌鸦) was jumping around. The crow watched them with disdain (笔试).
“You have no flying skills at all!” he said to the swans. “All you can do is to move your wings. Can you turn over in the air? No, that’s beyond you. Let’s have a flying competition. I’ll show you what real flying is!”
One of the swans, a strong young male, took up the challenge (挑战). The crow flew up and began to show his skills. He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan.
Now it was the swan’s turn. He flew up, and began flying over the sea. The crow flew after him, making all kinds of comments (评价) about his flying. They flew on and on till they couldn’t see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so exhausted that he found it hard to stay in the air, and had to struggle to keep himself from falling into the water.
The swan pretended (假装) not to notice, and said, “Why do you keep touching the water, brother? Is that another trick? “
“No,” said the crow. He knew he had lost the competition. “I’m in trouble because of my pride (自大) ! If you don’t help me, I’ll lose my life...”
The swan took pity on him, and took him on his shoulders and flew back to the beach.
