The first breath-taking pictures of the Earth taken from space showed it as a solid ball covered by brown land masses and blue-green oceans. We had never seen the Earth from that distance before. To us, it appeared as though the Earth had always looked that way and always would. Scientists now know, however, that the surface of the Earth is not as permanent (永久的) as we had thought.

Scientists explain that the surface of our planet is always moving. Continents moves about the Earth like huge ships at sea. They float on pieces of the Earth's outer skin. New outer skin is created as melted rock pushed up from below the ocean floor. Old outer skin is destroyed as it rolls down into the hot area and melts again.

Only since the 1960s have scientists really began to understand that the planet Earth is a great living machine. Some experts have said this new understanding is one of the most important revolutions in scientific thought. The revolution is based on the work of scientists who study the movement of the continents-a science called plate tectonics.

The modern story of plate tectonics begins with the German scientist Alfred Wegener. Before World War One, Wegener argued that the continents had moved and were still moving. He said the idea first occurred to him when he observed that the coastlines of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one and then split apart.

Wegener was not the first person to wonder about the shape of the continents. About 500 years ago, explorers thought about it when they made the first maps of Americas. The explorers noted the east coast of North America and South America would fit almost exactly into the west coast of Europe and south Africa. What the explorers did not do, but Wegener did, was to investigate the idea that the continents move.

Have you ever stayed deep underground in a cave? You have no food and the oxygen(氧气) is running out. You're not even sure if anyone knows you're down there.

A soccer team of 12 young Thai boys, as well as their coach, had to go through this experience this summer. They became trapped in a cave in Thailand on June 23, spending 18 days inside until they were saved by an international team of divers(潜水员). After hearing the news that a former Thai Navy SEAL(海 军海豹突击队员)died while trying to save these kids, my friends and I talked about the situation and felt as if there might be no way to get the children out.

But we held out hope anyway. We refused to give up hope for these kids, even when the situation seemed quite dark. We were rewarded(奖励)for our hope when they were finally saved.

It can be hard to hold out hope in dark times. Every day, we read or hear about the terrible things that happen in the world. This makes it hard for us to stay positive. Some people go through their lives thinking that the worst is always just around the corner.

However, I believe that it's especially important to stay positive during difficult times. This is the best way to deal with the challenges that we face in life. As people often say: there is always a light at the end of the tunnel(隧道).

In students' daily talks, celebrities are usually a hot topic, including their dress, behavior, families and other personal things. Then, is it a celebrity job to be a good role model? Please read the following students' debate.

Is it a celebrity’s job to be a good role model?

It's a celebrity job to be a good role model because people usually look up to stars. If a celebrity drinks and smokes, his fans will follow him because they look up to the celebrity so much. If a celebrity's lifestyle is inappropriate for kids, then their parents should be more careful about what they let their kids see.

I think everyone should try to be a good role model, even if you are not a celebrity! You can still be a role model to your sisters and brothers a younger neighbor, or anyone. But I be very good because they are role models for so many people !

A celebrity doesn't have to try to be a good role model. They are famous because they worked hard at what they love for a living. They should, however, try to make good choices for themselves, not their fans. Lots of stars have to post apology letters after being caught doing bad things. It's good, but if the only reason they do is to win back their fans, it's not good

Although it is a wonderful thing to be a good role model, that's not what the celebrities must do. They are famous because they love what they do and are good at it.
