After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered a planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacec raft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the right distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.What did scientists find in September 2010?

Have you ever asked your relatives or friends if there is Wi-Fi in their houses? Have you ever searched for Wi-Fi when you are at restaurants or hotels? The answers will probably be "Yes". Most of us want Wi-Fi everywhere as if we can't live without it. But we can only use free Wi-Fi in some public places. We still have to spend some money accessing (连接) the Internet at most time. Here comes a piece of good news.
A rich, powerful organization in the USA called the Development Media Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. They will send up hundreds of satellites into low Earth orbit (轨道) in 2015.
This is because they have made a survey and found that only 60% of the world's population have been able to get information on the Internet. And this is also because many countries are unable to offer people the necessary infrastructure (基础设施) to access the web.
We can expect to use free Wi-Fi everywhere in the near future.

On the first day of school our teacher introduced himself and challenged us to get to know someone we didn’t already know. I stood up to look around when a gentle hand touched my shoulder. I turned around to find a little old lady with a warm smile. She said, “Hi, handsome. My name is Rose. I’m eighty-seven years old.”
“Why are you in university at such a YOUNG age?” I asked. She replied, “I’m here to meet a rich husband, get married, have a couple of kids, and then retire and travel.” I knew she was joking. I was curious (好奇) what might have encouraged her to be taking on this challenge at her age. “I always dreamed of having a university education and now I’m getting one!” she told me. We became friends. Every day we would talk nonstop after class. I always enjoyed listening to this “time machine” as she shared her wisdom (智慧) and experience with me. And Rose easily made friends wherever she went.
At the end of the term we invited Rose to make a little speech. She cleared her throat and began, “We do not stop playing because we are old; we grow old because we stop playing. I’ve learned a few secrets to staying young, being happy, and achieving success. You have to laugh and find humor every day. You’ve got to have a dream. When you lose your dreams, you die.”
“There is a huge difference between growing older and growing up. Anybody can grow older. That doesn’t take any talent or ability. The idea is to grow up by always finding the opportunity in change...”

The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (抢劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (监狱). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.
Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences (证据).
