When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.
However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.
People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn’t reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.Warneken and his partners worked with ________.

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).
