The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them.
But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless （无害的）thing.
Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired.
Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth.
Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again.
Perhaps these comets that never return have broken into pieces. For some astronomers think that shooting stars(流星) are pieces of broken comets.

Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don’t have enough time to spend taking care of everything yourself, dome helpers may be the best choice.
After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides(农药) or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence(围栏) or a gate so that only you and your workers can get in and out.

In 1926, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo. The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything clearly, even the smallest thing. This kind of photo was called a Daguerreotype(银版照相). Soon other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains. In about 1840, photography was developed. Then photographers could take picture of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the US worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike(栩栩如生的). Photography also became one kind of art by the end of the 19^th century.

Have you seen Avatar? It’s a popular 3D movie, and you may have to wear a special pair of glasses – 3D glasses, to see it. The 3D glasses make the images from the movie look as if they are coming straight at you.
3D movies are really exciting to watch. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?
When we look at an object, each eye sees it at a different angle (角度). Our eyes send the two images to our brain, and the brain puts them together. 3D technology uses two film projectors (投影机)。 One projects left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy (头晕的) or have headaches.
Dr John Hagan, an eye doctor in Kansas City, said if your eyes can’t focus on the same object at once, you will have trouble watching 3D movies.
小题1:What is Avatar?
