Seeing in Stereo

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(影像)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 objeets 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 Drovides 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 tinv insect eye sees only a tiny part.Besides，what if you needed glasses? Be glad for the eyesight that you have.

67.According to the passage，an eye is like a camera because both

A.can record images B.can imagine objects

C.provide centered images D.work at the same height

68.Stereoscopic sight is a result of having

A.a three-hundred-sixty-degree field of sight

B.hundreds of eyes，all seeing parts of an image

C.two eyes close to one another that work together

D.one eye on either side of the head，each seeing a different image

69.The underlined word “perceived’’ in Paragraph 3 means

A.set B.taken C.seen D.understood

70.The author implies that “seeing in stereo”

A.is similar to the way cameras work

B.is an ability humans are fortunate to have

C.would be better for a wider field of sight

D.helps people to havelbetter sight than animals

根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Puppy Food

A puppy(young dog)is a precious addition to any family.The excitement of bringing home a little furry friend will always live in our memories.Like all of us，though，your puppy must have adequate nutrition right from the start to make certain that it'll have a long and healthy life.

71 You might ask yourself what is the best for your new pet with all of the different varieties on the market in all of their attractive packaging. Some dry food produced specially for puppies is the best for the development of their teeth. 72

Contrary to the belief of many first-time puppy owners，it is not always the best idea to purchase food that is too high in calcium(钙)，protein，and vitamin levels. 73 In addition, a high intake of calcium is associated with bone disease in large-breed dogs.If you have a “smallbreed” puppy，you can buy that kind of food.

It is not a good idea to feed the food you eat to your puppy frequently，as your puppy may become selective about food. 74 Some people think that dog biscuits and other treats are fine, but they should not be a main part of puppy’s diet.

Young puppies should be fed three times a day.Each puppy is unique，however，so feeding them twice a day is acceptable.After ten to twelve weeks of age，feed your puppy twice per day.Allow your puppy to eat as much as he would like in fifteen minutes. 75 If you let your puppy eat too much or too often by keeping food accessible at all times，he may become overweight and have health problems as an adult.Like humans，your puppy will not enjoy the food any longer if it is there at all times

A.Pick up the dish with the remaining food.

B.Proper food is a basic necessity for your puppies.

C.Remember to give your puppy the food he would like to have.

D.It can also cause an upset stomach due to an unbalanced diet.

E.A further benefit is that it is less expensive than the canned food.

F.One example is that extra helpings of nutrients do harm to digestive organs.

G.It’good to provide the extra nutrients a puppy needs until he grows larger.
