Example Input: 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."

Example Input: Article: A long weekend is a great opportunity to do something a little different. Many people use a long weekend for a getaway, a short trip to leave the stress of their everyday lives behind and explore, learn, or relax. Hotel Romance Many hotels and resorts feature something special to start the getaway, such as champagnes , flowers, or a fruit basket in the room on arrival. Getaway packages usually include a room with something special, a heart shaped bed, for example. Additional benefits could be room service meals or other private dining, plus tickets or discounts for local attractions. Visit a Spa Spa getaways can take place at a location that focuses only on spa services or at a hotel that offers a spa as one of its features. Some spas emphasize treatments fit for their geographic area or a local attraction. A spa in a grape growing region might provide grape juice masks, or a hotel near a hot spring could offer mineral baths. Most spas offer a range of massage , health and beauty treatments, so a spa getaway can be relaxing with other benefits. Learn a Skill A long weekend may not be enough time to become an expert at something new, but it provides a way for people to begin their explorations. Some organizations offer intensive courses that last two or three days. People with special interests can get away from their routines while learning such things as how to make beer, speak a new language, or take better photos. Help Others Some organizations cooperate with businesses to have accommodations and activities for short-term volunteers. Most volunteer vacations involve ecology friendly or charity activities. A volunteer getaway is a way to relieve stress and help others at the stone time. Stay in a National Park For those who want to relax in a rural environment, a national park fits the bill. Most national parks provide camping areas for tents and trailers. Several have cabins within the parks available to rent. A getaway to a national park provides privacy, stress relief, and the time to get to know some important natural resources.

Example Input: Article: Beginning college is exciting: new ideas to explore, new challenges to be met and many decisions to be made; your future begins here. However, you will find college life is different from your previous school environment. Many of us can be easily overwhelmed by the details of running a well-balanced life. While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you. The following you may find of use about life on campus: *Plan well. There are so many new things to do at a new college or university. Give yourself time to make new friends and became familiar with the campus, but don't forget why you are there. Give some time for social activities and manage your time wisely. *If you don't have a "system" for planning your time now (like a day timer a computer data book). get one. Most of all, don't depend on your memory. *Don't miss the guidelines. The restrictions, rules and regulations of all kinds can usually be found in your student's handbook. Consider them well-balanced food for thought. What dates are important? What pieces of paper need to be handed in? What can / can't you do in your student residence ? Who has the right for what? What do you need to complete to graduate? *Write the word "STUDY" on the walls of our bedroom and bathroom, and maybe it will help to to write it on a piece of paper and stick it on the telephone, TV and the kitchen table. Consider this -- you are paying thousands of dollars for your course. You pay every time you have to repeat or replace a course. *Build your identity. This is the time for you to decide what to do and what not to do. Take as much time as you need to explore new ideas. Do not be afraid of the beyond. This is learning to make good choices.
