To find out whether bees（蜜蜂）can see colours, the following experiment is made. A round table is put in a garden, and on the table is a piece of blue cardboard（硬纸版）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（蜂房）and give the syrup to other bees in the hive. Then they return to the feeding-place which they have found. 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. Very soon bees arrive again, and fly straight to the blue card. None go to the red card.
1. How many cards do you need to prepare for the experiment?
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

3. During Step 2 of the experiment, the bees go to ________.
A. the blue card with syrup on it
B. the new blue card with no syrup on it
C. the empty space where the original（原先的）blue card was
D. the new blue card with syrup on it on the left of the red card
4. The experiment has proved（证明）that bees ________.

Now satellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare（比较）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.
1. Satellites travel _____________.
A. in space B. in the atmosphere
C. above the ground D. above space
2. Why do we use the weather satellites to take pictures of the atmosphere? Because __________.
A. the weather satellites can do it easily
B. clouds form there
C. the weather forms there
D. the pictures can forecast the weather
3. Meteorologists forecast the weather __________.
A. when they have received satellite pictures
B. after they have compared new satellite pictures with earlier ones
C. before they received satellite pictures
D. during they study satellite pictures
4. Maybe we’ll soon be able to forecast the weather for ________.
A. one day B. two days
C. five days D. seven days or even longer
5. The main（主要的）idea of this passage is that satellites are now used in _________.
A. taking pictures of the atmosphere
B. receiving pictures of the atmosphere
C. doing other work in many ways
D. weather forecasting

In almost every big university（大学）in the United States, football is a favourite sport. American football is different. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field. They have four chances（机会）to move the ball ten yards（码）. They can carry it or they can throw it. If they move the ball ten yards, they can try to move it another ten yards. If they move it to the end of the field, they receive six points（点）.
It is difficult to move the ball. Eleven men on the other team try to stop the man with the ball. If he does not move the ball ten yards, his team kicks the ball the other team.
Each university wants its own team to win. Many thousands of people come to watch. They all shout for their favourite team.
Young men and women come on the field to help the people shout more. They dance and jump while they shout.
Each team plays ten or eleven games each season.
The season begins in September and ends in November. If a team is very good, it may play another game after the season ends. The best teams play again on January 1, the first day of the New Year. Many people go to see these games and many others watch them on TV.

Snow fell on the mountain. It snowed and snowed. The snow did not melt（融化）. It became deep and heavy. The snow on the bottom pressed （挤压）together., it became ice.
The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a glacier（冰河）.
Sometimes the glacier moved only a few inches（英寸） each day. As it moved, it took rocks and dirt with it. It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and lakes.
A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers changed the land.
