Elephants in Uganda are starting to come close to villages near national parks. The big animals are a real danger to people.

    So, the Uganda Wildlife Authority has been giving people new tools to keep the elephants away: vuvuzelas. They are plastic instruments some fans use at sports events.

    The instruments make a loud sound elephants do not like. The animals leave, and no one is harmed. A spokesperson for the Uganda Wildlife Authority says vuvuzelas work because they do not threaten the elephants. That is important because an elephant that feels threatened is more likely to attack. So far, no one has reported an elephant attacking in answer to a vuvuzela.

    Officials and villagers have tried other ways to stop elephants from coming near farms and houses. They have built beehives – houses for flying insects that sting. They have hung ropes covered in spicy oil. They have dug long, deep holes. And they have used guns, called A-K47s.

    An official from the Uganda Wildlife Authority explains that people shoot the gun in the air to scare the elephant. But over time, the elephants have stopped being afraid of the sound of the gun. They only look at the shooter and wave their ears.

    Another official for the Uganda Wildlife Authority, Gessa Simblicious, says one elephant-prevention solution will not work everywhere in Uganda. And one day, elephants may accept the vuvuzela noise, just as they do the sound of the A-K47.

    But right now, vuvuzelas are an effective, non-violent and fun way to deal with a serious problem.

    Anyone can write a baby poem, and everyone enjoys reading them, young and old. Baby shower(婴儿洗礼) poems can have rhythm and rhyme, but they certainly don't have to. Poems can be either long or short, but short is probably best for your typical baby shower needs. You can add a little humor as well!

    The people who are most often touched by baby shower poems are those who have had children themselves. Sweet poems can remind them of the time when their little ones were still young. No one will appreciate them more than the family members themselves. If you are a creative writer or  have a special talent for putting words together in a special way, then you should try writing your own baby shower poems. This would make a great gift idea as well.

    If you decide to write your own baby poems, even common things can inspire you. Inspiration can be found anywhere. Look to your own memories from the past. What was special about your childhood? What special object have you treasured over the years? What words of wisdom(智慧) of advice could you pass on to the next generation? Look around the house and imagine a baby being there. What do you see, hear, or feel? Let those thoughts be the source of your best baby poems.

    When writing a baby poem, you do not have to write like Shakespeare, you just have to be sincere. Years later when the baby has grown，think of how special they will feel knowing the words were just for them.

    If you are not the creative type — don't worry! There are lots of places online where you can look for poems saying just the things you want to say. Poems have been written on all subjects throughout the ages, and baby poems and baby shower poems are no exception. A quick search online doesn't have to take any time at all.

    In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there. Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.

    But in the big cities of Europe like London or Pads, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.

    So they move out of the cities. Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.

    Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.

    As a result, quite a lot of people who have moved to the countryside move back to the city. "

    It's wonderful to see crowds in the streets and cinema lights," they say.

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart and fun,” Serval says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, from $99 to $199, and the U.S. is the first target market.

Do you know of anyone who uses the truth to deceive? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.

For example, some might say, "I just won a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!"

This guy's a winner, right? Maybe, maybe not. In fact, he bought $200 worth of tickets. He's really a big loser!

He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just dishonest.

Some politicians often use this trick. During Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents says, "During Governor Smith's term, the state lost one million jobs!" That's true. However, an honest statement would have been, "During Governor Smith's term, the state had a net gain of two million jobs."

Advertisers will sometimes use half-truths. It's against the law to make false statements sol they try to mislead you with the truth. An advertisement might say, "Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache." It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

This kind of deception happens too often. It's a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

It's always exciting to receive a letter in the mail. Even today, when the world is digitally connected, receiving an actual letter in your mailbox from a distant land is a great way for children to make new friends. 

The Peaceful Pen Pals Project is a beautiful initiative that combines global connection and self-expression. The project is part of the nonprofit Kids for Peace, founded by Jill McManigal and Danielle Gram in California, in 2006. Letter writing is most certainly hands-on and helps strengthen relationships throughout the world. 

The Peaceful Pen Pals Project is open to all children, ages 2 through 17. To date, there are 1500 children from 17 countries participating in the program. Each child is assigned a pen pal of a similar age. This establishes a point of connection right off the bat for the children and promotes a stronger bond. If the letter writers are in the same grade, they can chat about their schools, teachers, and what they are studying. They can also compare and contrast what different states or countries learn about and how the dynamics of the classroom are, whether socially or academically. 

Children may be more inclined to write about their issues if they feel like they are speaking to a peer in a similar situation. They also write about the local weather, who the letter writer lives with, and their favorite things to do at home. This will give the pen pal a good sense of the writer's home life, and they may relate to certain aspects, such as their parents, the number of siblings, or if they share a room. Although pen pals may live in different countries, they may find common ground according to this information. 

"Hearing first-hand stories from an international pen pal can encourage teens to take someone else's perspective and to think outside of themselves," writes Rebecca Fraser-Thill on Very Well Family. "It can also encourage interest in geography, politics, and history, and promote many key skills, including reciprocation, empathy and mutual concern. "
