G. D. GOENKA PUBLIC SCHOOL HOLIDAY HOMEWORK - 2010 Class IX ENGLISH To quote Philip Adams “When people say to me: ‘How do you do so many things?’ I often answer them, without meaning to be cruel: ‘How do you do so little?’” Multitasking is the need of the hour! It is our ability to do so many things at one time that enables us to cope with our responsibilities and pressures. This summer, the English assignment will help you to learn, enjoy and enhance your vision. Make a folder of about 12, A4 size sheets. Include the following in the folder and make an attractive title page, entitled: ‘The Journey of Life’. 1. An essay of about 250 words on how Travel has been of educational value to you (You may relate meeting people, learning customs and traditions, discovering art treasures and natural features, increasing general awareness) 2. A pictorial collage on ‘The India of My Dreams’ (A4 size sheet only). 3. A film review on one Hindi and one English movie that you watched during the holidays. The review should be original: it should include your comments on the story, cast, direction, script, music and special effects. 4. Use 2, A4 size papers and choose any 2 poets and quote from their famous poems. You can refer to poemhunter.com Enjoy the assignment as you ‘multitask’ your way through the summer holidays. The talents that you have are sure to shine through. We can use some of the outstanding works in the Goenkan Yearbook.
