Is there intelligent (有智力的) life on other planets? For years, scientists said “no.” or “we don’t know.” But today this is changing. Seth Shostak and Alexandra Barnett are astronomers(天文学家). They believe intelligent life exists (存在) somewhere in the universe. They also think we sill soon contact these beings(人;生物).
Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope(哈勃望远镜) have shown that there are at least 100 billion galaxies,” says Shostak. “And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth.”
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth? “Probably not,” says Shostak. “It’s a long way away. However, intelligent beings may contact us in other way, such as radio signals(信号). In fact, they may be trying to communicate with us now, but we don’t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.”

Taking part in charity is not just for adult people. Kids can do it too! Melvin Sheppard, 14, an American student, has done charity work for 8 years. He has also encouraged his classmates to join him.
Melvin studies at William Allen Middle School in Philadelphia. Recently, he collected $ 1,500 by himself and $487 from his classmates to donate to Cooper University Hospital.
Melvin was born nine weeks premature (早产的) in Cooper University Hospital, weighing 2.6kg. His father told him how Cooper saved his life, so he feels thankful to the hospital.
Melvin's classmates joined him once they found out about his kind behavior. Their teacher, Michael Bemer, also held a class with them about helping others. "It wasn't really about the money," Bemer said. "It was about the fact that they were doing something good."
"It feels great, helping someone that I know." said Jordan, Melvin' s classmate. Melvin's neighbors also helped out.
Since Melvin was 6, he and his parents have given money to Cooper University Hospital every year. This year, Gray E. Stahl, the head of the hospital, went to Melvin's school to accept the money.
The money goes to a part of the hospital that helps about 500 young patients every year.
"When they leave, we call them graduates," Stahl said, "my workmates and I are pleased when our graduates and their families do well, like Melvin and his family."

The students and teachers at Fairfield School think it’s necessary to look after the environment! This is what they’ve been doing:
Growing vegetables
Fairfield School students have their own vegetable garden. Both children and teachers plant and water the seeds (种子), then they pick the vegetables. And the vegetables are used in school meals. Now they can enjoy healthy food at lunchtime. “School meals are tastier than ever before!” says one pupil.
Recycling
The students don’t just bring their books to school ----- they bring their rubbish(垃圾) too! There are recycling bins (回收箱) in the playground for cans, plastic bottles, batteries and paper. The teachers give a prize to the student who works hardest to recycle every month.
Planting trees
‘This used to be one of the least beautiful areas of the city with no green areas,’ says the head teacher Lynne Johnson. ‘Now every child has planted their own tree, which he or she looks after during the week. They’ve made the view from the classroom more beautiful!’
Finding cleaner ways to get around
Everyone walks or rides to Fairfield School. “When the roads are busy, it’s faster to ride bikes than to go by car anyway,” says one student. Even the teachers don’t use their cars. “We can’t encourage our students to look after the environment if we don’t do it ourselves!” says one teacher.
