Read the following passage and complete the activities.
1. State whether the following statements are true or false. (2)
- Parents of young seagull guided his brothers and sisters in the art of flying
- The whole family kept taunting the young seagull for his cowardice.
- The young seagull mustered up the courage to take that plunge.
- The young seagull was with his mother on his ledge.
|
The young seagull was alone on his ledge. His two brothers and his sister had already flown away the day before. He had been afraid to fly with them. Somehow when he had taken a little run forward to the brink of the ledge and attempted to flap his wings he became afraid. The great expanse of the sea stretched down beneath, and it was such a long way down - miles down. He felt certain that his wings would never support him; so he bent his head and ran away back to the little hole under the ledge where he slept at night. Even when each of his brothers and his little sister, whose wings were far shorter than his own, ran to the brink, flapped their wings, and flew away, he failed to muster up the courage to take that plunge which appeared to him so desperate. His father and mother had come around calling to him shrilly, upbraiding him, threatening to let him starve on his ledge unless he flew away. But for the life of him, he could not move. That was twenty-four hours ago. Since then nobody had come near him. The day before, all day long, he had watched his parents flying about with his brothers and sister, perfecting them in the art of flight, teaching them how to skim the waves and how to dive for fish. He had, in fact, seen his older brother catch his first herring and devour it, standing on a rock, while his parents circled around raising a proud cackle. And all the morning the whole family had walked about on the big plateau midway down the opposite cliff taunting him for his cowardice. |

Read the following passage and do the activities.
1. Write whether you ‘Agree’ or ‘Disagree’ with the statements: (2)
- To accomplish goals, experts recommend a ten-step approach.
- The champions have to have the skill and the will.
- For anyone, setting goal is not easy but challenging.
- If we do not take actions to achieve goals, we shall not achieve them.

Champions aren’t made in gyms. Champions are made from something they have deep inside them-a a desire, a dream, a vision. They have to have the skill and the will. But the will must be stronger than the skill. Successful professionals thrive in the same manner. We all have natural talents. If we use that talent to set our goals in life, we can easily get success in life. We shall not achieve our goals if we do not take action to achieve them. Setting goals has two valuable assets - a sense of originality and a stepping stone to illuminate the path. Goals put one at the helm of life; pursuing them acknowledges a better future situation. They help to steer a course of life rather than simply drifting along and letting things happen. Setting goals may appear easy, but, for some, it is quite challenging. Fear of failure may be avoided in the absence of any goals. After all, one has to decide what one wants to achieve in the end. To accomplish goals, experts recommend a five-step approach. |
