Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 1th century, a greenhorn was a young cow or an ox whose horns (角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well. The Green Revolution(绿色革命)is the name given some years ago to the development of new kinds of rice and other grains. It was the result of hard work by agricultural scientists who had green thumbs.

Green is also the color used to describe the powerful feeling. Jealousy(嫉妒). The green eyed monster is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants.

In most places in the world, a green light is a signal(信号)to move ahead. In everyday speech, a green light means approval(赞成)to continue with a project.

Are you a fan of films? As we all know, for some films, you need 3D glasses to see them.I think it is easy to make your own 3D glasses instead of buying them.Let's have a try.

There are two ways to make 3D glasses. You can decide which way would be easier for you. The first way seems like the cheaper way but the things needed to make the glasses this way may not be things laying around the house. First print out a template(模板) for the glasses at http // paper project. org/ PDF files/3 dglasses. pdf. After you cut out the template, cut your cellophane (玻璃纸) to fit the holes in the glasses. Make sure you place the red cellophane on the left eye and the blue on the right. You can either stick or tape the cellophane inplace. You are now ready to use your glasses.

Another way you can make 3D glasses is to find an old pair of sunglasses. Take out the lenses(镜片). Get a piece of clear plastic and place the lenses on it, draw a line around the lens and then cut the new plastic lens out. Place the lens back into the sunglasses frame (框). Color the left lens red with a marker and the right eye blue. You now are ready to watch 3D films.
