Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out As a result，the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people，plants，and animals would all die of hunger．
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.

Ashok Gadgil has spent the past three decades helping people in need—and he has no plans to stop .On May 2, Gadgil won the$100．000 Lemelson-MIT Award for Global Innovation. Each year，the honor is given to an inventor who has improved the lives of people in developing countries. Gadgil‘s inventions have helped more than 100 million people around the world.
Gadgil is a professor and physicist at the University of California. When he’s not teaching，he works to find solutions to global problems such as energy efficiency and water safety. “I chose to focus on problems where my knowledge of science could help，”he said
In the 1980s he came up with a program to make energy-efficient light bulbs more affordable for people in developing countries. Then in the 1990s，Gadgil designed his first life—saving invention，UV Waterworks .The device kills deadly disease —carrying germs(病菌)from drinking water. It costs just one cent to clean five liters of water .Gadgil was inspired to find an inexpensive solution to the clean water crisis after more than 10，000 people in his home country of India died from an outbreak of Bengal cholera，in 1993 The disease is spread through contaminated food and drinking water .So far，the invention has provided safe drinking water to more than five million people in poor areas.

If you're like a lot of married guys, you don't need to be reminded about men being from Mars or women from Venus. Chances are that you're all too familiar with the feeling that you and your wife are from different worlds. When married people start noticing their fundamental differences, it can lead to a breakdown in communication. The way to have a successful marriage is through communication, common ground and understanding. Here are some pointers to guide you in the right direction.
Rather than ending up in an endless back and forth, forget about the issue for a minute. Instead, think about how you feel she's acting toward you and ask her if that's how she feels about you. If you think she's being unfair, ask her if she thinks you're being unfair. Switching the focus to that shared feeling can help your wife see things from your point of view.
It's important to accept the fact that there's a two-way street between you and your wife. If you think she doesn't make enough of an effort to see things from your point of view, you have to ask yourself if you're making an effort to see it her way.
Realize nobody can wave a magic wand to make you and your wife completely understand each other all the time. Many couples have an extremely close friendship and do almost everything together before they're married. Once you've tied the knot, you may begin to notice that you're not as alike as you once thought.
It seems obvious, but some guys get fooled into thinking their wife will be as excited about all of their interests and hobbies as they are. Don't be surprised when you find out that she's not just like "one of the guys." Sooner or later you'll realize that she might be going along with some of your interests just to make you happy.
Rather than feel offended if you find out she's not as into your favorite hobby as you thought, appreciate the effort she put into making you happy. Swallow your pride and try to take part in some of her hobbies, too, even if you might be a little put off at first. While you're not going to be trying on makeup with her, you could try baking a recipe together.
If either of you is always giving everything and getting nothing in return, there's going to be bitterness. The best marriages are built on compromise. You knew you were going to have to give and take for your marriage to work; now it's time to make it happen.

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At that time, the people were between the ages of eighteen and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The findings showed that stress levels dropped sharply after people reached their fifties.
Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.

A heartless thief is believed to have crashed a fund-raiser and made off with a bag of cash meant to help a New York City firefighter pay for life-changing surgery for his 9-year-old son. But little Aidan Sullivan -- who was born with a facial defect and no right ear -- yesterday put up a brave front, with a message for the crook(thief): "I'm going to kick your butt!"
"I want to look normal," said Aidan, whose father, Tim, is a firefighter in the Bronx. The third-grader has hemi facial micro soma, in which one half of the face doesn't develop correctly.
Last weekend, family friend Peter Drake, a Ridgefield, Conn., firefighter, hosted a fund-raiser, collecting between $8,000 and $9,000. But when the party at a Danbury, Conn., Irish cultural center was over, the money had disappeared.
"At the end of the night, all the money that was donated was put in a zippered bag," said Tim Sullivan. "A bartender gave the bag to Pete... He had it in his hands. He put it down to go do something, and when he came back, he saw that it was missing."
Sullivan said his longtime friend -- who has had fund-raisers to pay for Aidan's 10 previous surgeries -- is "devastated."
"Pete was so upset. He kept saying, 'I let Aidan down, I let Aidan down,” Colleen Sullivan, 40, recalled.
"We even went Dumpster diving, in case it was thrown out."
The Sullivans plan to go ahead with the March 1 surgery led by specialists at NYU's Langone Medical Center in Manhattan. The money would have offset the $10,000 to $15,000 that insurance doesn't cover. Yesterday, Aidan said he's not a fan of hospitals and doesn't like to be away from his sister, Kaylee, 4. But he's willing to do it. "I'm excited," he said. "Finally, an ear."
