If we want to deal with the association(社交) between boys and girls properly, here are some “dos and don'ts” for you to follow.
Keep a normal and healthy mind. Most schools and classes are made up of boys and girls. It is very natural for the boys and girls to make friends with each other. We should make as many friends as possible. We should get on with the other sex(性别) in public instead of in secret.
Don't be too nervous or too shy. If you are a shy person, you can also find a way out. First of all, you can make friends with the students who have the same interest and hobby as you. As both of you have much in common, you may have much to talk about. If you keep doing like that, little by little, you will gladly find you are also as free to express yourself as others.
Don't fall into the ditch of early love. Teenage boys and girls at a adolescence (青春期) are rich in feeling. They are easy to regard the friendship as a sign of love and fall in love with each other at an early age. In my opinion, early love is a green apple that can't be eaten. An apple won't taste sweet until it is ripe(成熟). Boys and girls at middle schools are too young to carry the heavy duty of love. Do keep out of early love.

A. tell students to keep away from early love
B. give school boys and girls advice on association

The London Olympic Games is coming soon. This summer, Chinese sports fans will be able to watch the exciting games in 3-D on CCTV.
Three-dimensional, or 3-D, means having three dimensions (维度): width, height and depth(深度). 3-D comes from the way the human brain and eyes work. When we look at something, each eye sees it from a different angle (角度). Our eyes send the two images (影像) to our brain, and the brain puts them together. The small difference between the image from the right eye and the image from the left eye allows us to see depth.
When we watch pictures and television in two dimensions, each eye gets the same information. That is because the image has no real depth(深度), and there is only one way of watching it.
So the skill of 3-D is to get a different image into each eye of the person. It uses two movie projectors (放映机). One projects a left eye image and the other projects a right eye image. While watching 3-D movies, we have to wear a special pair of glasses. The 3-D glasses allow us to see a different image in each eye. So the images from the screen look like they are there in the room with you.
However, the 3-D glasses make the screen look darker. What's more, people with eye problems may get headaches if they spend too much time watching 3-D movies, because their brains need to work harder to “read” the images. And people need to pay 2 or 3 times of money for a 3-D movie.

A. two movie projectors

A. 3-D glasses help people get the same image in each eye.
B. 3-D glasses make the screen look brighter.
C. A 3-D film needs two movie projectors to be made.
