Article: We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery . However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC) seen an increase in telephone calls about e-cigarette poisonings? The answer is children. Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick. Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation. Meaning, the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr.McAfee adds that liquid nicotine is a well-known danger. Mr.McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill, Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U.S.Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use. But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing.
Answer: Cheaper.

Article: Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle. There are many stages in the water cycle. Rain falls when water vapour in clouds condenses . Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes, and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle or pond in a mist above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It continues even if snow or hail fall instead because both eventually melt to form water. The amount of water vapour in the air depends on the temperature. The air is more moist in the tropics than in the cold polar regions.
Answer: Water cycle.

Article: For the kids in Matt Marciano's sixth-grade social studies class, Thanks-giving is a time for great ideas. "We look at different foods that people eat around the world," says Marciano. "The lesson," he explains, "teaches students to admit that some people are unlucky. And it also gets them thinking about Thanksgiving, about their lives, and about their biggest homework of the year--to find a way they can change the world." Last year, 12-year-old Christian D. taught basic soccer skills to 63 kids with cancer. Christian's classmate Brianna used the money she had raised to buy 56 teddy bears. She donated them to a woman's shelter. Both students say the experience taught them something they'll never forget: When we give something to others, we're really giving thanks. And giving thanks feels good. "Helping the woman smile, if just for a day, made me feel like I could make a difference," Brianna says. "And it taught me that I should always be thankful for what I have." Brianna's happiness is something Jeffrey Froh knows about. Froh studies how gratitude affects a person's mind and attitudes. Those who are thankful are more likely to help others. Grateful people and kids in particular are healthier and happier than those who are not. "Grateful kids tend to be happier and more satisfied with their lives," Froh says. "Kids who give thanks are happier with school, their families and their friends. Grateful children also feel less envy toward others, are less likely to be depressed and even do better in school." "To experience gratitude," says Froh, "a couple of things have to happen. First you have to notice that there is goodness in your life. Then you have to admit that the reason for that goodness lies partially outside of yourself."
Answer: They thought of ideas for helping other people.
