Bedazzling (眼花缭乱) with their bright colors and eye-catching displays, fireworks light up our night skies during the holidays. However, these crowd-pleasers can have some damaging side effects.
Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals—as well as some humans.
The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead—all found in fireworks—have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin(毒素) limits of the United States Clean Air Act.
Once all those chemicals come back down to the ground, they can cause problems too. Debris (碎片) from the fireworks falls to the ground, where animals can burn their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources.
Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started:
• Sky lanterns—a tradition that originated long ago in the most-populated Asian country.
• Party crackers—a favorite in the United Kingdom—give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers.
• Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns (号角) and blow up a storm!

Once there was a man who liked to eat mangoes(芒果). One day he decided to get the sweetest mango from the very top of the tree. Mangoes which are exposed to the sun the most are the sweetest.
So he climbed up to the top, where the branches were thin. He managed to pick up a few sweet reddish fruits, but, in an attempt to climb down, he slipped and started falling towards the ground. Fortunately, he caught the branch as he was falling and remained helplessly hanging on the tree. Then he started to call nearby villagers for help. They immediately came with a ladder and sticks, but could do little to help him.
Then after some time one calm and thoughtful person arrived - a well-known sage who lived in a simple hut nearby. People were very curious to see what he would do, as he was famous in solving many people’s problems in the area and sometimes very complicated ones.
He was silent for a minute and then picked up a stone and threw it at the hanging man. Everybody was surprised. The hanging mango lover started to shout: What are you doing?! Are you crazy? Do you want me to break my neck?” The sage was silent. Then he took another stone and threw it at the man. The man was very angry: “If I could just come down, I would show you!”
That’s what everybody wanted - that he came down. But how? Now everybody was tense(紧张), as to what would happen next! Some wanted to punish the sage, but they didn’t. The sage picked another stone and threw it again at the man, even more forcefully. Now the man on the tree was enraged and developed a great determination to come down and take revenge(报仇).
He then used all his skill and strength and somehow reached the branches which were safe to start going down. And he made it! Everybody was amazed.
However, the rescued man found the sage gone. He stood there, realizing that the man really helped him because he induced him to try his best and save himself.
