In Britain, some people say they will do anything if a famous person they love asks them to. One in three people in Britain have a new kind of disease—they love a famous person too much.

Some people love famous stars like Britney Spears, David Beckham or even Tony Blair. It is not just the young, grown-ups have the same problem. One in four people are so interested in their heroes that it affccts their life.

There are two ways of worshipping famous people. One way is just to follow them or talk about them with friends for fun. The other is a more serious way. People have very strong feelings for them and think they are their friends. People who do so for fun are found to be happier. But those who have strong feelings for a famous person are perhaps to feel more lonely and worried.

"Worshipping famous people is not certainly a bad thing," Dr. John, an expert said. "But like many things, overdoing it may not always be good for you."

The one-child policy in our country has made most families much smaller than before. That is to say, there are fewer children in a family. But the population of China is still growing faster. Why? In fact, it’s a serious problem not only in China, but also in the whole world. It’s reported that the world population is expected to reach 9,200,000,000 by 2050. There are two important reasons. First, there are still more and more babies born every year. Next, people in the world can live much longer than before.

The earth is too tired, but it has to burden(担负) more in the future. Who can save her?

①Have you ever shown your photos on your favorite social media（媒体）? Or have you expressed your feelings and emotions on your online page? If yes, do you know what you have posted on the social medias can cause problems you could not expect?

②Cathy, who is going to be fifteen, posted online an invitation to her birthday party with her address in it. And guess what! 500 people came to the party, and some even broke the windows and plants, making a total mess of the house. The girl’s birthday party turned into a nightmare（噩梦）.

③Many teenagers（青少年）think they know everything about social media, and that such a thing could never happen to them. Studies show that each year more than three million young people in the world get into trouble because of their online activities.

④So do remember these if you really want to share something online.

⑤Share with care! Not everyone will like what you write online. Think before you post anything. You never know who sees your texts, pictures or videos. Before clicking “post”, you should ask yourself, “How will I feel if my family or teachers see this?” and “How might this post be bad for me in five or ten years from now?”

⑥Be polite when you write! Imagine someone is unfriendly in real life. The same is true of online communication. No one likes it when you “shout” in your messages. If you feel angry or frustrated while you’re writing a message, wait a bit. Read it again later and then send it.

⑦Protect and respect! Never share your passwords with anyone. It’s not wise to post your home or email address online. Don’t say bad things about people. If you get messages like that or see them online, talk to your parents or your teachers.

⑧I’d say none of these things promises 100% online safety, but each will help you to be safer.
