17.People are being lured (引诱) onto Facebook with the promise of a fun,free service without realizing they're paying for it by giving up large amounts of personal information.Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don't realize this is happening.Even if they know what the company is up to,they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.
The biggest problem,however,is that the company keeps changing the rules.Early on,you keep everything private.That was the great thing about facebook-you could create your own little private network.Last year,the company changed its privacy rules so that many things-your city,your photo,your friends'names-were set,by default (默认) to be shared with everyone on the Internet.
According to Facebook's vice-president Elliot Schrage,the company is simply making changes to improve its service,and if people don't share information,they have a"less satisfying experience".
Some critics think this is more about Facebook looking to make more money.Its original business model,which involved selling ads and putting them at the side of the page,totally failed.Who wants to look at ads when they're online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington.In April,Senator Charles Schumer called on Facebook to change its privacy policy.He also urged the Federal Trade Commission to set guidelines for social-networking sites."I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,"Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy is only the beginning,which is why I'm considering deactivating(撤销) my account.Facebook is a handy site,but I'm upset by the idea that my information is in the hands of people I don't know.That's too high a price to pay.

12.Learning to study is not difficult.The first thing to remember is that you must be willing to learn.It doesn't mean that you must always like the subject.It does mean,however,that you must be willing to learn whatever is necessary.Try to understand why it is important and how it will help you now and later.Knowing mathematical facts will be useful in your whole life.Knowing how to spell words makes any kind of writing easier.Sometimes the subject that you think is going to be uninteresting and it will be attractive when you began to work on it.Learning things can be fun if you can try your best.
Here's some advice for you:have a certain time each day and a quiet place with good lighting for study,so that you can concentrate on your study without interruptions.Have everything ready before you sit down to study,a dictionary,paper,a pen and books.Be sure you understand what you should learn before you start.Read carefully and pay special attention to the most important things.When memorizing,find out the main parts and then recite the whole thing.Check your homework after you finish it.Never forget the importance of review and preview.
