He spent all his free time in one of his four glass-houses and grew flowers of every colour, with long and difficult names, for competitions (比赛). He tried to grow a rose of a new colour to win the silver cup (银杯) for the Rose of the Year.Mr. Flowers’ glass-houses were very near to a middle school. Boys of around thirteen of age were often tempted (引诱) to throw a stone or two at one of Mr. Flowers’ glass-houses. So Mr. Flowers did his best to be in or near his glass-houses at the beginning and end of the school day.But it was not always possible to be on watch at those times. Mr. Flowers had tried in many ways to protect his glass-houses, but nothing that he had done had been useful. He had been to school to report to the headmaster, but this had not done any good. He had tried to drive away the boys that threw stones into his garden, but the boys could run faster than he could, and they laughed at him from far away. He had even picked up all the stones that he could find around his garden, so that the boys would have nothing to throw, but they soon found others.At last Mr. Flowers had a good idea. He put up a large notice (布告) made of good, strong wood, some metres away from the glass-houses. On it he had written the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble; the boys were much more tempted to throw stones at the notice than at the glass-houses.1.It was Mr. Flowers’ hope to _______.A. build glass-houses in his free timeB. grow the Rose of the Year in a silver cupC. win a silver cup for growing a rose of a new colourD. grow a rose with the longest name2.Boys were often tempted to _______.A. throw stones at Mr. Flowers’ glass-housesB. throw stones at Mr. Flowers from their schoolC. be in or near Mr. Flowers’ glass-housesD. play with Mr. Flowers near his glass-houses3.Mr. Flowers stayed in or near his glass-houses _______.A. at times when schoolboys were walking near themB. all the school day when there were no boys aboutC. where he could not be seen by the boysD. in his free time at the beginning and end of the school day4.Mr. Flowers had tried to _______ to protect his glass-houses.A. be on watch in his free timeB. ask the headmaster for helpC. pick up all the stones around his gardenD. do all the above5.Mr. Flowers’ good idea was to _______.A. write some words on the glassB. put up a large notice to cover his glass-housesC. give the boys something else to throw stones atD. send for policemen
