Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.‘A good book for children should simply be a good book in its own right.' These are the words of Mollie Hunter, a well known author of books for youngsters. Born and bred near Edinburgh, Mollie has devoted her talents to writing primarily for young people. She firmly believes that there is always and should always be a wider audience for any good book whatever its main market. In Mollie's opinion it is essential to make full use of language and she enjoys telling a story, which is what every writer should be doing: 'If you aren't telling a story, you're a very dead writer indeed,' she says. With the chief function of a writer being to entertain, Molly is indeed an entertainer. 'I have this great love of not only the meaning of language but of the music of language,' she says. This love goes back to early childhood. 'I've told stories all my life. I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them, I said I wanted to work with dogs, and the teacher always said "Nonsense, Mollie dear, you'll be a writer." So eventually I thought that this woman must have something, since she was a good teacher - and I decided when I was nine that I would be a writer.’ This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical and gives a picture both of Mollie's ambition and her struggle towards its achievement. Thoughts of her childhood inevitably brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields - sadly now covered with modern houses. 'I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I'll never go back,' she said. 'Never.' 'When I set one of my books in Scotland,' she said, 'I can recapture my romantic feelings as a child playing in those fields, or watching the village blacksmith at work. And that's important, because children now know so much so early that romance can't exist for them, as it did for us.' To this day, Mollie has a lively affection for children, which is reflected in the love she has for her writing. 'When we have visitors with children the adults always say, "If you go to visit Mollie, she'll spend more time with the children." They don't realise that children are much more interesting company. I've heard all the adults have to say before. The children have something new.' Mollie’s adult visitors generally discover that _____.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions. TEXASA Texas middle school is under fire after students say they have been banned from speaking Spanish in class. The students say their principal announced the rule last month over the intercom. Inside the walls of Hemptead Middle School, a language controversy is brewing. “There’s one teacher that said, „If you speak Spanish in my class, I’m gonna write you up,” 8th grader Tiffani Resurez says. Four students say their principal’s announcement – banning them from speaking Spanish in class – has given teachers and fellow students a hall pass to discriminate. “She was like, „No speaking Spanish.’ She told me that. I was like, „That’s my first language.’ She said, „Well, you can get out,” fellow classmate Yedhany Gallegos says. A letter sent home by the superintendent says, “Neither the district nor any campus has any policy prohibiting the speaking of Spanish.” The four students feel that the statement from the superintendent has not been made entirely clear that their school. “People don’t want to speak it anymore and don’t want to get caught speaking it because they’re going to get into trouble,” 6th grader Kiara Lozano says. Parents, like Cynthia Zamora, believe the school is not getting to the root of the problem. She wants to know why the “No Spanish” announcement was ever made in the first place. “I was very surprised that she would even go to such lengths,” Zamora says. Many students at the school grew up speaking Spanish at home, and they say it often comes as second nature when they’re talking to each other at school. “I’m not scared. I’m gonna keep speaking my language. That’s my first language, and I’m gonna keep doing it,” Lozano said. The principal has been placed on paid administrative leave while the district investigates. A spokewoman for Hempstead Independent School District has released a statement saying, in part, “The district is committed to efficiently and effectively resolving this matter with as little disruption to our students and their learning environment as possible.” In the passage, the word “it” refers to _________.

Four students say their principal’s announcement – banning them from speaking Spanish in class – has given teachers and fellow students a hall pass to discriminate. “She was like, „No speaking Spanish.’ She told me that. I was like, „That’s my first language.’ She said, „Well, you can get out,” fellow classmate Yedhany Gallegos says. A letter sent home by the superintendent says, “Neither the district nor any campus has any policy prohibiting the speaking of Spanish.” The four students feel that the statement from the superintendent has not been made entirely clear that their school. “People don’t want to speak it anymore and don’t want to get caught speaking it because they’re going to get into trouble,” 6th grader Kiara Lozano says. Parents, like Cynthia Zamora, believe the school is not getting to the root of the problem. She wants to know why the “No Spanish” announcement was ever made in the first place. “I was very surprised that she would even go to such lengths,” Zamora says. Many students at the school grew up speaking Spanish at home, and they say it often comes as second nature when they’re talking to each other at school. “I’m not scared. I’m gonna keep speaking my language. That’s my first language, and I’m gonna keep doing it,” Lozano said. The principal has been placed on paid administrative leave while the district investigates. A spokewoman for Hempstead Independent School District has released a statement saying, in part, “The district is committed to efficiently and effectively resolving this matter with as little disruption to our students and their learning environment as possible.” What can we infer about the policy on no speaking Spanish?

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search. Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages. Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power. Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future. From the passage, it can be inferred that to solve our energy problems ________ .
