UNIT 4 Stories and PoemsLesson 23 The Giant (ii)習(xí)題2一、閱讀理解（一）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（硬紙版）with a drop of syrup（糖漿）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.Picture 11. How many cards do you need to prepare for the experiment?A. Two: one blue and one redB. Three: two blue and one redC. Three: one blue and two redD. Four: two blue and two red2. If Picture 1 below shows the table top during Step 1 of the experiment, which of A, B, C, D in Picture 2 shows the table top during Step 2?Picture 23. During Step 2 of the experiment, the bees go to _.A. the blue card with syrup on itB. the new blue card with no syrup on itC. the empty space where the original（原先的）blue card wasD. the new blue card with syrup on it on the left of the red card4. The experiment has proved（證明）that bees _.A. cannot see colors B. can see colorsC. can not see blue D. cannot see red5. Which of the following is the best title for the passage?A. Bees Love Blue B. Bees Love SyrupC. Bees, Color and Syrup D. Can Bees See Color?Keys: 15 BCBBD（二）Now satellites are helping to forecast（預(yù)報(bào)）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大氣）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（氣象學(xué)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（比較）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 atmosphereC. above the ground D. above space2. Why do we use the weather satellites to take pictures of the atmosphere? Because _.A. the weather satellites can do it easilyB. clouds form thereC. the weather forms thereD. the pictures can forecast the weather3. Meteorologists forecast the weather _.A. when they have received satellite picturesB. after they have compared new satellite pictures with earlier onesC. before they received satellite picturesD. during they study satellite pictures4. Maybe well soon be able to forecast the weather for _.A. one day B. two daysC. five days D. seven days or even longer5. The main（主要的）idea of this passage is
