  • 第18题：

    问答题
    Section C (10 marks)　　Lisa Tyler was weary after a long, hard day at the pottery factory where she works, but as she approached her home in the English city of Stoke-on-Trent, her heart lightened; soon she would be having a nice cup of tea, putting her feet up and watching Friends, her favourite TV series, But first, she needed to change out of her work clothes and pick up her three-year-old son from his grandmother’s house nearby.　　As Lisa walked up her garden path, she noticed a light flashing on and off in an upstairs bedroom. A shiver went down her back. . What if it was a burglar? Quietly, she crept round to the back of the house to see if there was any sign of a break-in. Sure enough, a window was open and someone’s coat was hanging on the gatepost!　　Well, 26-year-old Lisa didn’t fancy coming face to face with a burglar, so she ran to a neighbour’s house and rang the police. As she sat waiting for the police to arrive, Lisa’s curiosity got the better of her and she decided to go back and see what was going on. That’s when she saw a leg coming out of the downstairs front window. It was a man climbing out. Lisa gasped in shock. The burglar war carrying her portable television!　　At this point, Lisa saw red. She didn’t have many possessions and she’d saved long and hard to buy that set. Besides, nobody was going to stop her watching Friends.“Oh no, you don’t.” she muttered under her breath, as fury swelled inside her. Without even stopping to think, she across the garden and started shouting at the burglar, “Give me my TV—drop it now!”　　Ignoring her, the man fled across the garden, so Lisa threw herself at him and successfully rugby-tackled him to the ground. The burglar struggled to escape, but Lisa hung on like the best kind of guard dog, despite being punched and kicked. As she looked up, she realized that she recognized the burglar’s face. She was so surprised that she lost her grip and the burglar got away, leaving the TV behind in the garden.　　By the time the police and her father arrived, Lisa was in tears. “I can’t believe you were so foolish, Lisa,” scolded her father. “You could have been killed.”　　“I know, but at least he didn’t get my TV.” she replied.　　Lisa later remembered the name of the burglar, who had been in the same year as her at school. He was later caught and jailed for 15 months after committing a burglary and assault. In May last year, Lisa was given a Certificate of Appreciation by Staffordshire police for her “outstanding courage and public action”. In the future, however, she intends to leave household security to a new member of her family, Chan, who is a real guard dog.　　Answer the questions in no more than 10 words.　　1．What first led Lisa to think there was a burglar in her house?　　2．Why didn’t Lisa wait in her neighbour’s house until the police arrived?　　3．What does “Lisa saw red (in the 4th paragraph)” most probably mean?　　4．What did the burglar do when Lisa shouted at him?　　5．How did Lisa help to catch the burglar later?

    正确答案：
    1.A light flashed on and off in an upstairs bedroom. /Something was moving inside. 根据文章第二段she noticed a light flashing on and off in an upstairs bedroom. A shiver went down her back. . What if it was a burglar?可知a light flashing on and off in an upstairs bedroom提醒了她。在回答此问题时注意使用完整的句子。
    2.Lisa’s curiosity got the better of her. /She was eager to find out what was happening. 根据第三段中As she sat waiting for the police to arrive, Lisa’s curiosity got the better of her and she decided to go back and see what was going on可知是好奇使她想过去看看怎么回事,而不是在邻居家等着.
    3.She got angry. 根据这句之后她想到自己没有多少财产,她省了很长时间的钱才买了这台电视,而且没人能阻止她看《老友记》,可知她内心十分生气,在下一段作者明确提出fury swelled inside her,可知她十分生气。
    4.He ignored Lisa and fled across the garden. 根据文中Ignoring her, the man fled across the garden可知他没把Lisa放在眼里,就跑过庭院逃跑了。
    5.She later remembered the name of the burglar. /She realized she could identify him. 根据倒数第四段she realized that she recognized the burglar’s face以及最后一段Lisa later remembered the name of the burglar, who had been in the same year as her at school. He was later caught…可知是由于Lisa想起窃贼的名字帮助了警察破案。
