Years ago，if a teenager had some problems in his life，he might write them in his diary. Now he might get on the Internet and write them in his blog(博客). In many ways，a diary and a blog are almost the same. Then，what makes a blog different from a diary?

The biggest difference is that a blog is much more public than a diary. Anyone can read what you write in your blog. Usually，a teenager likes hiding his diary book and treats it as secret. If you are not satisfied with a friend and write something bad about him in your diary，he will never know it. However，if you do this on the Internet，that friend may read your blog and get angry. So we have to be careful of what we write.

A blog has good points，of course. People choose to write in blogs，they know that their friends will read what they write. If you feel sad one day and write in your diary，no one will know about it. If you write the same words in your blog，your friends may quickly write back to comfort you and offer their help. Blogs help people know what their friends are doing.

Though it's a good way to write blogs about everyday life，I still prefer my old diary.

Yesterday and Today

Life in the twenty-first century will be different from life today. Between then and now many changes will take place, but what will the changes be?

The population is growing fast. There will be many people in the world and most of them will live longer than people live now.

People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruit and vegetables. Maybe people will be healthier.

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.

    A visit to a doctor's office costs from 15 to 50 dollars. It's so expensive. Many people in the United States think that doctors are overpaid. However, most doctors disagree. They say that they were asked to study medicine for a long time. Tuition for many years of medical education costs a lot of money. Doctors say that it is necessary for most medical students to borrow money from the bank to pay their tuition. Because their money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.

    Therefore the cost of medical care in America is high. Because high tuition is one cause of high costs, one way to lower costs would be to have medical school that are free or have low tuition.

    D. the high cost of tuition in medical schools is one reason for the high cost of medical care in the USA
