To discover whether bees can see colors, the following experiment is set up. A table is put in a garden, and on the table is a piece of blue cardboard (硬纸板) with a drop of syrup (糖浆) on it. After a short time, bees come to the syrup. The bees then fly to their hive (蜂蜜) and give the syrup to other bees in the hive. Then they return to the feeding-place which they have discovered. After a while, the blue cardboard with the syrup on it is taken away. Instead of this card, a blue card is now put on the left side of the first feeding-place and a red card to its right. These new cards have no syrup on them. Thus, the blue card is on the left, the red card on the right, and there is nothing where the first blue feeding-card used to be. Very soon bees arrive again, and fly straight to the blue card. None go to the red card.
1. To do the experiment, altogether how many cards do you need to prepare?
A. Two, one blue and one red. B. Three, two blue and one red.
C. Three, one blue and two red. D. Four, two blue and two red.
2. If figure 1 (图1) below shows the table top during step 1 of the experiment, which picture in
figure 2 represents (代表) step 2?
(blue card with syrup blue card red card )
3. During step 2 of the experiment, the bees come to ______.
A. the original (原来的)blue card with syrup on it.
B. the new blue card with no syrup on it.
C. the empty space where the original blue card was.
D. the new blue card with syrup on it.
4. The experiment has proved that bees ______.
A. cannot see colors. B. can see colors.
C. cannot see blue. D. cannot see red.
5. Which title best gives the idea of the passage?

Benin
Benin is one of the smallest African states. It lies in West Africa on the Gulf (海湾) of Guinea, to the south of Burkina Faso and Niger, between Togo on the west and Nigeria on the east.
Benin used to be called Dahomey and was controlled and ruled by France from 1893 to 1960, when it became independent (独立). In 1963 the army general Soglo overthrew (推翻) the first president. Maga. Soglo set up an army government and called himself head of state in 1965, but was overthrown and replaced (取代) by a civilian (非军人) government in 1967. In December 1969 Benin had another change of power with the army again taking over (接管). In May 1970, Maga and two other men set up a new government, with each of them acting as president in turn for two years. However, half a year after Maga turned over power to the second man Ahomadegbe, the three-man government was overthrown by the army once more and General Kerekou became president. In November 1975 Kerekou changed the name of the nation from Dahomey to Benin, Benin being the name of a 17th century kingdom covering the same place. Kerekou also announced that Benin would be a People’s Republic based on Marxism-leninism.

Have you eaten too much over the holidays? You should try fidgeting for a while. Those around you might not like it, but scratching (moving your nails (指甲) against a part of your body) and twitching (moving suddenly and quickly when you don’ t want to) is an important way of burning up calories (卡路里).
American researchers have found that some people’s squirming (continuously turn your body when nervous) and wigging (move in small movements, especially from side to side) equals (等于) several miles of slow running each day.
The scientists, based at the National Institute of Health’s laboratory in Phenix, Arizona, are studying why some people get fat and other stay slim.
In one study 177 people each spent 24 hours in a room in the institute where the amount (量) of energy is measured by their oxygen and carbon dioxide (二氧化碳) levels. By the end of the day, some people had burned up 800 calories in toe-tapping, (moving the front part of your foot up and down) finger-drumming (hitting your fingers continuously and lightly against something hard) and other nervous habits. However, others had burned up only 100 calories.
The researchers found that slim women fidget more than fat women, but there was no significant difference in men. Heavy people burn up more energy when they fidget than do thin people.

3. Scientists found in the experiment that ____ .
A. the energy burned up by fat people when they fidget was more than that burned up by thin people when they fidget
B. some people’s fidgeting burned up more than 800 calories, but some people’s fidgeting burned up less than 100 calories
C. slim women fidget more than fat women but fat men fidget more than thin men

Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光线) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.
Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts(霜冻) which might come at might and fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.
1. The huge mirror would ______.
A. stand 60 miles in height (高度). B. be 60 miles from side to side.
C. cover 60 miles of the earth. D. be 60 miles above the earth.
2. The mirror would be used to ______.
A. reflect (反射)sunlight. B. absorb (吸收) sunlight.
