【题目】 Have you wondered why you have two eyes and why they are set close together on the front of your face? The reasons are simple and important to the way you see the rest of your world.

Your eyes are like two small cameras. A camera catches an image of an object and records it on film.Similarly,when you look at something,each eye takes in what it sees and sends this image to the back of the eyeball.Because your eyes are set close together,they view the world from about the same height but from slightly different angles. Working as a team, the eyes send the images to your brain, which puts them together into a single, centered image.

Seeing in stereo means seeing with two eyes working together,which is called stereoscopic sight.This allows you to view the world in three dimensions,or 3-D.Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it.If images are coming from only one eye, however,only two of these dimensions-height and width-can be perceived.A world seen with one eye is thus two-dimensional,as in a photograph.

Now consider why your two eyes are on the front of your face.Think of other animals with this same arrangement.They are all animals that hunt,like lions and wolves.Their eyes face directly in front of them.This provides a field of sight about 180 degrees wide,which is called binocular sight.On the other hand,animals that are hunted have eyes on the sides of the head,which provides nearly 360-degree field of sight.In order to stay alive,they need to see things coming from the sides and from behind.However,without stereoscopic sight,they have difficulty determining how far a danger is.

With sight both stereoscopic and binocular,humans share with animal hunters the ability to see from side to side and to accurately determine the distance.If you think it would be great to have another type of sight,perhaps with hundreds of tiny eyes like many insects do,think again! Each tiny insect eye sees only a tiny part.Besides,what if you needed glasses? Be glad for the eyesight that you have.

【题目】Chinese people take their food and eat it extremely seriously. Eating is a communal (公共的), social, human experience in China. Sharing a meal is a sign of friendship and trust. Eating plays a central role in friendship, business, medicine, family and love. In short, food is life.

When eating, the rice is separated into your own personal bowl, but the dishes are placed in communal bowls in the center of the table and everybody helps themselves with chopsticks. It's considered polite, and sign of respect and friendship, to encourage other people to eat plenty of the good bits, even to pick up food with your chopsticks and drop it into their rice bowls for them.

Food is an important component of weddings, funerals and almost all Chinese festivals. New Year is the time for dumplings, the Dragon Boat Festival is the time for sticky rice Zongzi wrapped in leaves, and Mid-Autumn Day is the time for Moon Cakes. The dinner table is the best forum (公共讨论场所) to close business deals, and it's the number one thing to do with friends.

Chinese women express their admiration for the opposite sex by cooking delicious meals of many courses, and these days it's the other way round.

In short, if you want to get to know Chinese people, understand Chinese culture and thinking and get into Chinese life, you have to eat and appreciate Chinese food.
