Bees and colour
On our table in the garden we put a blue card, and all around this blue card we put a number of different grey cards. These grey cards are of all possible shades of grey and include white and black. On each card a watch-glass is placed. The watch-glass on the blue card has some syrup in it; all the others are empty. After a short time bees find the syrup, and they come for it again and again. Then, after some hours, we take away the watch-glass of syrup which was on the blue card and put an empty one in its place.
Now what do the bees do? They still go straight to the blue card, although there is no syrup there. They do not go to any of the grey cards , in spite of the fact that one of the grey cards is of exactly the same brightness as the blue card. Thus the bees do not mistake any shade of grey for blue. In this way we have proved that they do really see blue as a colour.
We can find out in just the same way what other clours bees can see. It turns out that bees can see various colours, but these insects differ from us as regards their colour-sense in two very interesting ways. Suppose we train bees to come to a red card, and, having done so, we put the red card on the table in the garden among the set of different grey cards, this time we find that the bees mistake red for dark grey or black. They cannot distinguish between them. This means that red is not a colour at all for bees; for them it is just dark grey or black.
That is one strange fact; here is another. A rainbow is red on one edge, violet on the other. Outside the violet of the rainbow there is another colour which we cannot see at all. This colour beyond the violet. invisible to us, is called the ultra-violet. Although it is invisible, we know that the ultra-violet is there because it affects a photographic plate. Now, although we are unable to see ultra-violet light, bees can do so ; for them ultra-violet is a colour. Thus bees see a colour which we cannot even imagine. This has been found out by training bees to come for syrup to various parts of a spectrum , or artificial rainbow, thrown by a prism on a table in a dark room. In such an experiment the insects can to taught to fly to the ultra-violet, which for us is just darkness.
1. What does the experiment with the bees in the first and second paragraphs tell us ?
A. Bees regard blue as a colour.
B. Bees like the blue colour.
C. Blue attracts more bees than any other colour.
D. Blue is the only colour to attract bees.

2. What does the experiment tell us in the third paragraph?
A. Bees are attracted only by the red colour.
B. Red is too bright a colour for bees.
C. Bees do not regard red as a colour.
D. Bees like red as well as blue.

3. Why did the experimenters create an artificial rainbow for their experiment?
A. To identify how good bees’ eyesight was.
B. To test whether bees could see ultra-violet light as a colour.
C. To see whether bees can recognise the 7 visible colours at once.
D. To check whether bees prefer some colours in a spectrum.

4. What does the fourth paragraph tell us concerning bees and colours?
A. Bees can recognise certain invisible colours.
B. Bees can recognise ultra-violet that is invisible to humans.
C. Bees may be harmed by ultra-violet light.
D. Bee’s work may affect a photographic plate.

5.What can we conclude from the passage?
A. Bees can see more colours than humans.
B. The ability to recognise colours varies from bee to bee.
C. Bees are more sensitive to colours than humans.
D. Bees recongnise colours, but somewhat differently from humans.

理工A65-2：
Dining custom
Every land has its own dining custom, and the United States is no exception. American feel that the first rule of being a polite guest is to be on time. If a person is invited to dinner at 6:30, the hostess expects him to be there at 6:30 or not more than a few minutes after. Because she usually does her own cooking, she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come if he is late, the food will not be so good, and the hostess will be disappointed. When the guest cannot come on time, he calls his host or hostess on the telephone, gives the reason, and tells at what time he thinks the can come.
As guests continue to arrive, the men in the group stand when a woman enters and remain standing until she has found a chair. A man always rises when he is being introduced to a woman. a woman does not rise when she is being introduced either to a men or a woman unless the woman is much older.
When the guests sit down at a dinner table, it is customary for the men to help the ladies by pushing their chairs under them.
Even an American may be confused by the number of knives, forks, and spoons beside his plate when he sits down to a formal dinner. The rule is simple however: Use them in the order in which they lie, beginning from the outside. Or watch the hostess and do what she does. The small fork on the outside on the left is for salad, which is often served with the soup. The spoon on the outside at the right is for soup. And so on. sometimes there is a separate little knife, called a butter spreader, on a small bread-and –butter plate at the left . As the bread is passed, each guest puts his piece on the bread-and –butter plate.

The sea
What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?
The first thing to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land the sea covers three quarters of the world.
The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan, where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place, there would be 2 kilometers of water above it! What a deep place!
If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are more salty than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live in the Dead Sea!
In most parts of the sea, there are plenty of fishes and plants, some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating these.
The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder.
Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometers!

Rockets in the sky
If someone asked you, “what color is the sky?” I expect that you would answer, “blue.” I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air.
We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air.
What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars.
Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal.
The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon because the air reaches only 240 kilometers. Then there is no air. But there is something that can fly even when there is no air. This is rocket.
I am sure that you are asking. “How does a rocket fly ?” if you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through the neck if the balloon and this pushes the balloon through the air. It does not need wings like an airplane.
This is how a rocket works. It is made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air.
Pockets can fly far out into space. Pockets with men inside them have already reached the moon. Several rockets, without man inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space.
1. What color is the sky?
A. It is the blue.
B. It is white.
C. It is grey.
D. It has no color.

2. When an airplane flies too high,
A. The air will be too thin to support its wings.
B. The air will become thicker.
C. The air will exert pressure on it .
D. The air will disappear in no time.

3. Which of the following heavenly bodies is not in the sky?
A. The sun.
B. The moon.
C. The earth.
D. The Morning star(Venus).

4. A rocket can fly to the moon because
A. It looks like a balloon.
B. It is much lighter than an airplane.
C. It doesn’t have wings.
D. It works like an untied balloon.

5. A rocket is pushed up into the air when
A. Hot gas rushes out of its head.
B. It is powered by gas.
C. Hot gas rushes out of its bottom.
D. Hot gas rushes out of its neck.

Transportation
For many years in the desert, camels used to be the only form of transportation. Before the age of modern trains, camel trains used to carry all the goods for trading between Central Africa and Europe. Traders sometimes used to put together camel trains with 10,000 to 15,000 animals. Each animal often used to carry as much as 400 pounds and it could travel twenty miles a day. This form of transportation used to be so important that camels were called the “Ships of the desert.”
Now modern trains travel across the desert in a very short time. One engine can pull as much weight as 135,000 camels. In addition, trains use special cars for their load. Refrigerator cars carry food; boxcars carry heavy goods; stock cars carry animals; and tank cars carry oil.
Air travel is also a modern means of transportation, but it has changed since the early twentieth century. The earliest planes were biplanes, with two sets of wings. The top speed of this plane was 60 miles per hour. The pilots used to sit or lie on the wings in the open air. The plane engines sometimes used to stop in the middle of a trip. It used to be impossible to fly in bad weather. In snow or in rain, the wings frequently used to become icy. Then the plane might go down.
Mechanical improvements during the first world war changed airplanes. Monoplanes took the place of biplanes. Pilots flew inside of covered cabins. Still, even these planes were small. Only rich people used to be able to travel in airplanes.
Now modern jets make air travel possible for all people. No place in the world is more than 24 hours away by jet. Further improvements have lowered the cost of flying, and they have made air travel much safer than it used to be. People never used to eat, sleep, or watch movies on airplanes. Now these things are a usual part of air travel.
1. According to the passage, why were camels called the “ships of the desert”
A. They were famous for their strength and patience.
B. They were the only means of transportation in the desert.
C. They were animals most suitable for transportation in the desert.
D. They could store plenty of water in their stomach while traveling in the desert.

2. Which of the following about the advantages of a train is not mentioned in Paragr
