Hurry and Worry

One evening, it was past nine, and I suddenly remembered I had to buy a new pair of shoes since my old ones were in a terrible state. We quickly decided to go to the nearest mall. Everyone dressed quickly and rushed to the car. I, as usual, was the last one to reach. Mummy sat behind with a disapproving expression on her face. “Yes, yes I know, don’t tell me,” I said almost stumbling into my seat, “Haste makes waste!”

We reached after nine-fifteen and there Dad took another ten minutes to park the car. Then we hurried to the shoe store. Thankfully I spotted the pair of shoes I wanted right away and they fitted perfectly. Daddy paid up immediately. “What about a light snack?” said Trisha. We all thought it was a good idea. We went into a restaurant and quickly ordered our choice of fair.

I decided to call Raj and tell him I had bought a pair of handsome shoes. I put my hand into my pant pocket and got the shock of my life. My mobile set was missing. Had I left it at home? No! that could not be. In fact, I remembered calling up Raj before leaving home.

Mummy was quick to sense that something was wrong. “What is it?” she asked. After some hesitation I said, “I think I’ve lost my mobile.” This was followed by anger, scoldings and expressed feelings of disgust. Everyone came up with suggestions as to where I could have left it. None were helpful. “Let’s go to the shoe shop,” said mother. “Yes,” I said, “maybe it dropped out of my pocket while I was trying on the shoes.” Leaving our snacks unfinished, we rushed to the store. It was almost 10, time for closing up. Two of the salesmen looked at us as we walked in, surprised. The third, however, put his hand in his pocket and took out my mobile set. “Is this what you w3ere looking for?” he asked. “Thank you, thank you,” I yelled, and Oh Goodness gracious! I had found my mobile at the same place where I thought I had left it.

Form Utter Destitution to Success!

I know of a lady named Kantabai. She lives in a remote village near Ahmednagar. She came from a very poor and destitute family. She did not receive any formal education, but learnt how to read and write from a neighbour. She was married at a very young age to a very elderly man, because she had no dowry. This man ill-treated her and even subjected her to physical abuse. Finally she complained to the police authorities. No one there paid any attention to her grievances. Her parents were not willing to take her back because it would result in shame for the family. She left her home and walked miles. She was tired and on the point of wanting to commit suicide.   

Then she met a middle- aged lady who ran a home for oppressed woman like Kantabai. The lady took Kandabai to her institution and brought her back to health. This was a milestone in her life. Then Kantabai began involving herself in matters dealing with women who had suffered at the hands of their in-laws or husbands. She took up their cause with a will and earned a name for herself as a crusader of justice. Today she is the head of the Panchayat and involved in many projects for the development of the village. However, prime on her agenda, even now, is woman-empowerment.

Thus did Kandabai overcome all odds and achieve success in the field she had chosen. Her story is indeed a lesson for all women who face such situations in society.

Write a story based on the following title: “Say ‘No’ to corruption!’

Say ‘No’ to Corruption!

Shantidevi lived in a chawl and had to work hard to make both ends meet. She wanted admission for her daughter in a municipal school. However, when she approached the headmaster of the local school, he agreed to give the admission provided she paid him Rs.5000/-

Shantidevi was faced with a dilemma. She knew that if she borrowed from some people she knew, she would be able to make up the required sum, and reply it over a period of time. There were people in her neighbourhood who were willing to help her and who told her that she had no choice but to pay. However, Shantidevi was strongly resentful of the very idea of having to pay a bribe.

Firmly, she came to a decision. She approached the Anti-Corruption Bureau (ACB) in her locality and acquainted them with the situation. They advised her to arrange for the money and when she did, the notes were marked. Then, along with one of the women officers of the Bureau, she went to the school and approached the Principal. She handed over the bundle of notes to him. He took them, counted out the money and put them into the drawer. Then he signed a letter giving her child admission to the school. Immediately, the lady officer with Shantidevi informed him of her credentials and announced that he was under arrest for the corrupt practice of accepting a bribe.

Shantidevi was praised for her action. She had, in no uncertain terms, said ‘no’ to corruption. Our nation requires more people like Shantidevi to rid it of the malaise of corruption.

To Catch a Thief

One night, my sleep was suddenly disturbed by some strange noises coming from the direction of the drawing room. It was dark and I took a look at the radium dial on my watch. It was 3:30 a.m. who could that be in drawing room?

I got up from my and taking the torch near my bedside, tiptoed softly into the room. What I saw there gave me a shock of my life. I could see a shadow busily engaged in ransacking the place. I could make out that it was a tall burly man. He had a sack into which he was putting in articles of the house, hurriedly, one after other- our laptop, the alarm clock, our DVD player amongst other things.

I was afraid and didn’t know what to do. There was no way I could tackle this thief single-handedly. I had to get help. I slipped back into my room and from there went to my parent’s bedroom. T shook my father awake and quickly put a finger on his lips, motioning him to silence. I whispered, “Papa, there’s a thief in the house.” Quickly he got up, without disturbing mother, looked around and found a walking cane. The two of us went barefoot into the drawing room.

The thief was too busy to notice us. Father went softly to the main door of our house. There were a few minutes of tense silence, which seemed liked hours, as father unlatched the door without making any noise. Then father began shouting, “Chor, chor,chor!” The thief turned around in alarm and made for the door, bur father blocked his way. I too was shouting at the top of my voice. There was a brief tussle between father and the thief.

Within moments, however, neighbours had come to our rescue and the thief was quickly overpowered.

We called in the police and the thief was arrested. It seems he was a notorious criminal and the police had been on the lookout for him for sometime. They praised our efforts at apprehending a man who was wanted by the police.

Write a story about a situation when you became the laughing stock of your friends:

Just for Fun!

It was the first of April and I was late for school. In my hurry, I hadn’t realized the significance of the date. My teacher looked at me sternly as I entered the class, but didn’t say anything. In knew that she was angry with me because of what had happened the previous day in class. Teacher had gone out of class for a while and Shiva had pinched me, just for fun. I retaliated by tackling him. He started laughing loudly and begged me to stop. Just then the teacher walked in and she gave both of us a good piece of her mind. She even threatened to report us to the headmaster.

During lunch break, the head boy of the class came up to me and said, “Vasu, the headmaster wants to see you in the office right away.”

I was panic-stricken. Would he ask me call for my parents? Would he suspend me from school? I was terrified.

Trembling with fear, I went to the office and knocked.

“Come in,” I heard the sharp voice of the headmaster.

I walked in diffidently. “Yes, Sir,” I said, my voice shaking nervously, “You called for me.”

“You’re Vasu, aren’t you?” I nodded my head. “No, I didn’t call you. Whoever gave you that idea?”

“But… but… Anto , the head boy told me…”

“Child,” his voice rose in anger, “Don’t you know that today is April Fool’s Day? you’ve been made a fool of. I have good mind to call in Anto and tell him to keep his April Fool jokes out of my office.”

“Sorry, sir,” I said and walked out, embarrassed and angry. All my friends were waiting down the hall and laughing uproariously. “April Fool, April Fool,” they shouted. For a while, I was angry, but then suddenly I saw the humour of the situation and began laughing too I was so relieved that the situation was not as serious as I had imagined.

Population census in India – 2011

The census for 2011 was declared on March 2011. The total population of the country was found to be 1.21billion. There were more than 627,000 village in the country but only about 2000 towns and cities. The rural population accounted for about 70% of the total population. The population of male in India was about 63 crores, which was about 52.66 per cent of the total population. The female population was about 58 crores, which was about 47.34% the adult literacy rate is now about 74%. Across the nation, the average density of the population is 382 persons per sq. km. About 44% of the population in India, is made up of the youth ( below 16years of age).

Mobile phones should be banned in schools.

View: Mobile is a big distraction- Being young, students tend to misuse it- Some are addicted to games and SMS.

Counterviews: In this modern era, when electronic equipment forms such an integral part of our lives, it is foolish, and even, cruel to say that mobile phones should be banned in schools. I do agree  that students may and do make unnecessary use of the mobile to send messages and play video games. However, the mobile is a very important means of communication. What if there is a sudden crisis? What if a student has no means of  getting transport to reach home because of rains are some other reason? What if a student faces some difficulty or problem on the way home or in school and needs to get in touch with his or her family immediately? What if some stranger harasses a student on the way home? There are many occasions when the mobile becomes an important accessory to possess. There can be a rule enforced that students must keep their mobiles switched off during school hours. This will ensure that the mobile is not misused during learning periods. However, banning the mobile completely would leave the student completely cut off from his or her family or friends during times when the student is facing a serious problem. Hence, I completely disagree with the suggestion that mobiles should be banned in schools.

The TV set should be thrown away.

View: watching TV affects the imaginative power of the children- It also affects the thinking capacity. No wonder it is called the ‘idiot box’- It is a sheer waste of time- TV watching is mostly done at the cost of good habits like reading.

Counterviews: TV is wonderful invention, and like any other invention it must not be misused. For that matter, bookworms are not better than couch potatoes. As far imaginative power, there is no conclusive evidence to prove that TV adversely affects the imaginative power. On the contrary, the viewers are exposed to fantastic visuals and they, in turn, trigger of the imagination. Further there are a good number of programs which challenge the thinking power of the viewer. We all know that quiz programmes where great hits on TV. Many such programmes have participatory elements and they, in my view, enhance our thinking skills. Reading habit among children may be on the decline. For reasons we must look elsewhere. Throwing the TV set out of the window is not a solution. And then again, there are good books and bad books. Reading trash is as bad as watching poor quality TV programmes. All these boils down to one thing: reading, watching TV, playing games are all parts of our life. Too much of anything is bad, and that goes for TV also.

The elderly: the real ‘torch bearers’

View: They have experience of life- They teach us values – they guide us to solve problems.

Counterview: Although I have the deepest respect for the elderly and cherish their loving presence, I wouldn’t really describe them as ‘torch bearers’. No doubt, during their time they have faced odds and carved pathways around obstacles. Yet, you will have to agree that the present is not the past. Things change rapidly. The elderly, however, are not very much in tune with the present. They are unable to cope with the changing world. Besides, they are conservative, stubborn and reluctant to try out new ideas. They are usefully insistent upon imposing their own ideas upon others, which may be outdated. In this sense they, very often obstruct progress.

In my opinion, it is the youth who can be and, in fact, have to be the real ‘torch bearers’ of the nation. They are the ones who are in the flow and stream of affairs. They are the ones who are fully conversant with present difficulties and the possible solutions. They are the ones who have invite and innovative ideas. They have the vigour necessary to launch movements and pioneer new pathways to progress. Hence, it naturally follows that they are the ones who can and should lead the way and show the way to others. For all these reasons, I can confidently assert that it is the youth and not the elder who are the real ‘torch bearers’ of the nation.

Develop s story with the help of the following points:

Court of Akbar - all courtiers and Birbal present - Akbar has two flowers in his hand - similar in every way - challenges courtiers to guess which is real and which is artificial – courtiers handle flowers – cannot make out the difference – Birbal quietly opens the windows of the court – a bee flies in and sits on one flower – Birbl claims that is the real flower – Akbar pleased at Birbal’s cleverness.

Artificial or Natural?

Once in the court of Emperor Akbar, when all the courtiers, including Birbal, were present, Akbar posed a challenge before them. He had two flowers in his hand. Both were similar in every way. Akbar announced that one of the flowers was real and the other was artificial. He asked the courtiers if they could determine which was the natural flower.

The flowers were passed through the hands of all the courtiers, but they were so ingeniously similar that no one could tell the difference. Even the fragrance of both was the same. Birbal too handled the flowers, but there was an expression of doubt on his face. After some thought, Birbal quietly asked the guards to open the windows of the Darbar. There was complete silence for some time. All the courtiers were puzzled at Birbal’s action. Then suddenly from the court garden, a bee buzzed through one of the windows. It flew about here and there for some time. Finally it came to one of the flower and settled upon it.

“That Jahanpanah,” said Birbal, “is the real flower. The other one is artificial.”

As usual , Birbal was right. Akbar was greatly pleased at Birbal’s ingenuity. He praised Birbal for his understanding of the ways of nature and for his quick, clever, conclusion.

To be good sportsman, one needs to develop sportsmanship.

To be good sportsman, one needs to develop sportsmanship. Some qualities of true sportsmanship have been given in the web below. Write a paragraph using the points. You may use the points in any order that you choose. You may also add a few points:

   

 The True Spirit of Sportsmanship

The main quality required for true sportsmanship is putting in one’s best into the games. Besides being a skilled player, he or she should enjoy the game. A true sportsperson plays with a spirit of competition, not rivalry. He or she should respect the opponent and even learn a few lessons from him or her. Observing the game of the opponent can give an idea of the strategy one has to use in order to win. If is a team game, the sportsperson should possess a team spirit. When the sportsperson is victorious, he or she should be humble about it. In the event of defeat, he or she should accept it cheerfully. All these qualities are the marks of the true spirit of sportsmanship that every sportsperson should display.
