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.

 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.

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.
