The soldiers were, therefore, given training in camouflage. They were shown how to paint their trucks in irregular patterns with pale green, yellow, and brown paints, and then to cover them with nets to which they had tied small pieces of cloth.The driver of the biggest truck had a lot of trouble camouflaging it. He spent several hours painting it, preparing a net and searching for some heavy rocks with which to hold the net down. When it was all finished, he went for lunch.When he came back from his meal, he was surprised and worried to see that his camouflage was completely spoilt by the truck’s shadow, which was growing longer and longer as the afternoon advanced. He stood looking at it, not knowing what to do.Soon an officer arrived, and he, too, saw the shadow, of course.“Well,” he shouted to the poor driver, “What are you going to do about it? If an enemy plane comes over, the pilot will at once know that there is a truck there.”“I know, sir,” answered the soldier.“Well, don’t just stand there doing nothing!” said the officer.“What shall I do, sir?” asked the poor driver.“Get your spade and throw some sand over the shadow, of course!” answered the officer.1.From this passage you can know ________.A.there were a lot of trees where the soldiers were stationedB.the soldiers were staying in an area far from the enemy planesC.the soldiers knew nothing about desertD.the soldiers had lived in desert before2.Which of the following is right?A.The nets with which they covered their trucks were made of small pieces of cloth.B.The soldiers tied small pieces of cloth to the nets with which they covered their trucks.C.The nets covering the trucks were painted pale green, yellow and brown.D.The trucks were tied to the nets with small pieces of cloth.3.The soldier was surprised and worried because ________.A.his truck had cast a shadow in the sun and the enemy plane would find it.B.the shadow of his truck was growing longer at noonC.it was late in the afternoon, and he could not get rid of the shadowD.his newly-painted truck was in the shadow4.What do you think of the ending of the story?A.It is quite reasonable that the officer ordered the soldier to cover the shadow with sand.B.We’ll laugh at the officer’s order because it is where the humor lies.C.Though the officer’s order sounded wise, the soldier couldn’t cover the shadow.D.The soldier managed to cover the shadow with sand5.What do you think of the ending of the story?A.It is quite reasonable that the officer ordered the soldier to cover the shadow with sand.B.We’ll laugh at the officer’s order because it is where the humor lies.C.Though the officer’s order sounded wise, the soldier couldn’t cover the shadow.D.The soldier managed to cover the shadow with sand
