[EX Q]: Article: Experts believe that storms and severe weather in North America and Asia have disrupted bird flight paths across the world and swept huge numbers of bird species towards the British Isles. Birds flying to the other side of the Atlantic or to the Pacific to lay their eggs have been trapped in Britain and Ireland, adding their numbers to native species, and causing great excitement in the bird-watching community. Local birdwatchers have already observed a total of 442 species in the British Isles this year. The highest number ever seen in one year is 445, in 2008. "We only need four more to break our record," said Lee Evans, who runs the British Birding Association. "With three months to go I'm sure we'll do it." Last month an extremely rare Siberian Rubythroat bird was seen in Scotland, sending hundreds of birdwatchers north in the hope of catching a glimpse of this colourful Asian beauty. Another very uncommon bird, the bufflehead duck was cited in Cornwell and caused similar excitement. "I couldn't believe it," said Evans. "The poor thing was completely _ . It must have been blown to England by the storms while trying to fly from Canada to the southern United States for the winter. That's 3000 miles!" Evans said that global warming over the past decade was playing a key role in transforming bird movements across the world. In addition, melting Arctic sea ice may also be opening up bird flight paths over the North Pole, making it easier for birds from the Pacific -- such as the slaty-backed gull and tufted puffin, both of which appeared in London earlier this year -- to reach Britain. Bird-watching is becoming an increasingly popular hobby among all age groups, added Evans. "A fifth of our members are under 18. This is a round-the-year hobby that you can enjoy from the kitchen window or from a car. More and more people are bird-watching, and as a result more and more unexpected species are being spotted in the British Isles."
Question: What is the passage mainly about?
Options: (A) The results of global warming. (B) Changes in the British bird population. (C) Increasing environmental pollution. (D) Worsening British weather.

[EX Q]: Article: Characters in novels don't always do what the writer wants them to do. Sometimes they cause trouble, take on lives of their own, or even work against the writer. It's not just a problem for inexperienced authors: famed children's novelist Roald Dahl said he got the main character in his bookMatildaso "wrong"that when he'd finished his first version, he threw it away and started again. Of course it's not the characters' fault. The problem lies with the author. Take Stephen King, who admitted that writing working-class characters is more difficult nowadays because his own circumstances have changed. "It is definitely harder,"King said."When I wroteCarriemany years ago, I was one step away from physical labour." This is also true for characters' ages, added King."When you have small children, it is easy to write young characters because you observe them and you have them in your life all the time. But your kids grow up, it's been harder for me to write about this little 12-year-old girl in my new book because my models are gone." For other authors, such as Karen Fowler, there's one quality that can stop a character in its tracks: boredom."I had particular problems with the main character in my historical novelSister Noon,"she says."She had attitudes about race and religion that seemed appropriate to me for her time and class, but they were not attitudes I liked. Eventually I grew quite bored with her. You can write a book about a character you dislike or a character you disagree with, but I don't think you can write a book about a character who bores you." According to Neel Mukherjee, it was Adinath, a character inThe Lives of Others, who made him work the hardest."I think I struggled because it's difficult to write a character whose most prominent personal feature is weakness, as Adinath's is, without making that feature define him,"Mukherjee says. But a troublesome character is far from an unwelcome guest, he continues, arguing that "when characters work against the author they come alive and become unpredictable". "That is a fantastic thing to happen,"Mukherjee says."I celebrate it. It is one of the great, lucky gifts given to a writer."

[EX Q]: Article: Have you ever noticed advertisements which say "Learn a foreign language in 6 weeks, or your money back! From the first day your pronunciation will be excellent. Just send..." and so on? Of course, it never happens quite like that. The only language that is easy to learn is one's mother tongue. And think how much practice that gets! Before the Second World War people usually learnt a foreign language in order to read the literature of the country. Now speaking a foreign language is what most people want. Every year millions of people start learning one. How do they do it? Some people try at home, with books and records of tapes; some use radio or television programmes; some use computers and network; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like learning a foreign language at school. A few people try to learn a language fast by studying for 6 or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary. They need the language in order to do their work better. For example, scientists and doctors chiefly need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the student's work for him.
Question: According to some advertisements, you _ .
Options: (A) have to pay your money if you cannot master a foreign language in 6 weeks (B) needn't pay you money if you cannot learn a foreign language in 6 weeks (C) must pay your money if you cannot master a foreign language in 6 weeks (D) will be paid much money if you cannot learn a foreign language in 6 weeks
