There are many things we need to know, but we do not learn them at school. For example, if we want to use our money wisely, we need to shop carefully. We need to know how to compare(比较) the prices of the things in different shops. We also need to know how to make the best choice when we shop .
Knowing how to make such choices is a life skill, and we need to practice it in our daily life.

It is common to believe that learning just takes place in school, but much of human learning happens outside the classroom, even from birth and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn subjects like reading, writing, and maths. They also continue to learn a lot outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with many changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and influences almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Scientists, social workers and other human service workers need to understand how certain experiences change people’s behaviors.
Learning is closely related (相关的) to memory, which is the storage(储存) of information in the brain (大脑). Scientists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later offers knowledge when we need it. However, scientists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences. ?

Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possible problems with social networking sites and the teenagers who use them.

    Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.

Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.

A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.

Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.

    Therefore, it’s very important to make sure teens are safe when they use social networks.

    Many of the same rules that work for online chat work for these sites:

※ Don’t use your real name.

※ Don’t give out personal information to people you don’t know. A last name and a town

are enough for a bad guy to find where you are.

※ Don’t believe that people are who they say to be.

※ Immediately end any communication that makes you uncomfortable and report it to a

       parent.

Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.
