  1. Read the following poem and answer the questions given below. 2×5=10

                        Honest Thought and Simple Truth

How happy is he born and taught

That serveth not another’s will;

Whose armour is his honest thought,

And simple truth his highest skill!

Whose passions not his masters are,

Whose soul is still prepared for death

Untied unto the world of care

Of princely love or vulgar breath;

Who hath his life from rumours freed,

Whose conscience is his strong retreat

Whose state can neither flatterers feed,

Nor ruin make accusers great;

Who God doth late and early pray

More of His grace than gifts to lend;

Who entertains the harmless day

With a well-chosen book or friend;

This man is free from servile bands

Of hope to rise or fear to fall;

Lord of himself, though not lands;

And having nothing, he hath all.

In the cold mountainous regions of North India, where it is very cold, travellers are helped to keep warm in this way. They take a small vessel, put burning coal in it, and cover it up. They weave strings around it and, wrapping it with cloth, carry it under their arms. Three men were travelling thus towards the sacred place of Amarnath. One of them saw several others suffering with cold, and, taking the fire out of his vessel lit a fire so that everyone could get warm. So everyone left the place alive. When they had all to walk in the dark the second man of the party took out the fire in his vessel and lit a torch with it, and helped them all to walk along in safety. The third man of the party mocked them and said: `You are fools. You have wasted your fire for the sake of others.’ `Show us your fire, ‘said they to him. When he broke open his vessel there was no fire, but only ashes and coal. With his fire one had given warmth and another had given light. But the third man was selfish and kept the fire to himself, and it was no use even to him.

V Read the following passage and answer the questions given below.         (10 marks)

Two men, both seriously ill, occupied the same room. One man was allowed to sit up in his bed for an hour each afternoon to help drain the fluid from his lungs.

His bed was next to the room’s only window. The other man had to depend all his time flat on his back. The men talked for a long time every day. Every afternoon when the man in the bed by the window could sit up, he would pass the time describing to his roommate all the things he could see outside the window. The man in the other began to live, for those one-hour periods where his world would be broadened and enlivened by all the activity and colour of the world outside. The man described all the beautiful things in the park outside. He told him about the people passing by. Ducks and swans played on the water while children sailed their model boats. Young lovers walked arm in arm amidst flowers of every colour of the rainbow. Days and weeks passed.

One morning, the nurse arrived to bring water for their baths only to find the lifeless body of the man by the window. He had died peacefully in his sleep. The attendants took his body away. After a little while, the other man asked if he could be moved to the bed next to the window. The nurse was happy to make the change. And after making sure he was comfortable, she left him alone. Slowly, painfully, he propped himself up on one elbow to take his first look at the world outside. He tried very hard to look out of the window. There was only a blank wall.

The man asked the nurse what could have compelled his deceased roommate who described such wonderful things outside the window. The nurse answered that the man was blind and could not even see the wall. She said,” Perhaps he just wanted to make you happy.”

Questions:

  1. Why were the two men admitted in the hospital?
  2. How did they spend their time?
  3. What did the man describe?
  4. What happened to the man by the window one morning?
  5. Why did the man encourage the other man in his room?

VI        Read the following story and answer the questions given below.  (10 marks)

 

The Enlightened Butcher

 

This story from Mahabaratha brings to light that our spiritual achievement is useless if we neglect our duties or Dharma.

 

Kaushika was his parent’s only son. “Mother,” he said one day, “ I want to go off into the jungle and devote myself to spiritual studies.” His mother said with concern, “but son, your father and I are very old. Your father is sick and he can hardly move. If you go away, what will happen to us? Who will attend to our needs?”

 

Kaushika did not listen. He was determined to study the Vedas. His mother cried in vain as she watched her son turn his back on her and leave for the jungle. Eventually Kaushika acquired great mystical powers.

 

One afternoon, as he was meditating under a tree, a crane flew up, and perched herself on a branch above Kaushika. Some bird droppings fell on Kaushika head. Kaushika furiously threw a gaze at the crane. The crane immediately fell dead. The sage felt sorry for what he had done. “How could I have allowed my anger to take over me that way?” He mourned.

 

Later in the day, he went to a village to beg for alms. The lady of the house asked him to wait and went to get some food. Right then her husband arrived. She immediately set aside the pot of food she was taking to the sage and went to her husband. After washing his feet, giving him food, and attending his needs, she came back out to give the alms to the sage. The sage was very insulated. “You put your husband before a pious sage? Do you know the power of a Brahmin?” he asked.

 

She calmly replied, “Yes, a true Brahmin is he who has mastered his anger. Please do not threaten me, I am not a crane that will die with your fiery gaze.” The sage was amazed. How does she know about the crane?” he wondered.

 

The lady continued, “Oh holy one! You are a learned Brahmin but you have not understood the truth about virtue. If you want to be enlightened, go to Dharmavyadha

who lives in Mathura. Anyone will tell you where he lives.”

 

The sage thanked the lady and hurried to Mathura. “He must be a great and learned sage indeed,” Kaushika thought to himself. But when he finally reached Dharmavyadha’s place, he found it to be a butcher’s shop! A very ordinary looking man came out and said, “Welcome holy one. I am Dharmavyadha, the man you seek.”

 

How can a butcher be spiritually enlightened? Kaushika asked in amazement. Dharmavyadha smiled and said with compassion, “ I know the story of the crane and of the woman who sent you here. Come, let us go to my house.”

 

 

 

 

 

 

[EL 1064         Sub: English For Empowerment]

 

The sage could not contain himself and blurted out, “But killing animals is such a sinful profession! Are you not ashamed?” “I am not,” the butcher calmly said. “ I am engaged in my family trade. I work hard and honestly at it. There is no reason for me to be ashamed of my work!”

 

“Holy one,” continued the butcher. “If I do injury to other creatures, so do you as you did to the crane.” “As we walk on the soil, we are trampling on numerous creatures. Nor is air devoid of creatures. You see the farmer tilling the land? He is killing so many animals that thrive under the soil.”

 

They reached the butcher’s house. The Butcher’s wife was doing her household chores and his two boys were playing. The butcher introduced the sage to his wife and boys. Then the butcher entered the house and touched his parent’s feet. “Here is a learned Brahmin from a far off place,” the butcher told his father. “Welcome, holy one”, the father said.

 

Before leaving the room the butcher remarked, “ My parents are my Gods. My wife and my children attend to them with devotion and love. We consider caring for them to be our greatest duty. In doing one’s duty cheerfully, lies true virtue. This is what the dutiful wife sent you to learn.”

 

“Oh learned one!” the butcher continued, you have run away from your responsibilities and deserted your aged father and mother. Spiritual achievement is useless if one has neglected one’s Dharma, or duties.” The sage remembered his mother crying, “ Who will look after us when you are gone my son?”

 

The sage apologized, “You have shown me the path of true virtue, the true meaning of Dharma, Oh pious one. I am deeply indebted to you”. Kaushika immediately returned to his parents and served them lovingly till the end of their days.

 

Answer the following questions from the passage in complete sentences.

 

  1. Why did Kaushika leave the house and his parents?
  2. Why did Kaushika kill the crane?
  3. Why did the lady in the house make Kaushika wait for his alms?
  4. What is the profession of Dharmavyadha?
  5. How did Dharmavyadha explain the virtue of his profession?

Good Teachers = High Academic Achievement

by Karena O’Riordan

Recognizing that a school technology program is only as successful as the teachers who use it, the Milken Exchange on Education Technology has introduced the Professional Competency Continuum (PCC), a road map for educators to use to assess their skills in integrating technology in the classroom..

In order to answer a question many states, districts and schools are struggling to answer — What are the skills for the digital age classroom? — the Milken Exchange gathered a panel of experts to identify areas where teachers’ professional skills should be developed in order to become effective users of technology. The experts’ recommendations grew into the key elements of the PCC.

The goal of the Milken Exchange has always been to promote higher academic achievement in schools. “Using technology for technology’s sake has little academic value,” says Edward Coughlin, author of the PCC. “We think that education systems should first set high academic standards that are appropriate for their students, and then work towards those goals using technology as one tool in the process. There is no question that technology helps move students forward academically, but it must be used wisely.”

The PCC is part of the Milken Exchange’s series, Seven Dimensions for Gauging Progress with Technology in Schools and represents the third of the seven dimensions: professional competency.

“Our seven dimensions are being used all over the country in training programs, school districts and staff development initiatives,” says Cheryl Lemke, executive director of the Milken Exchange. “The PCC helps those efforts by prescribing the specific steps educators can take to effectively integrate technology in their classrooms.”

The PCC includes a set of introductory scenarios describing “how it could be” in technology-rich classrooms. While some of the scenarios depict situations that seem futuristic or expensive, all the technologies described — as well as the contexts in which they are used and the research supporting their credibility — are available. Yet few of them are encountered in our nation’s school districts. “The goal of creating the PCC is to encourage teachers to think beyond the traditional classroom with its antiquated structure and learning style,” says Coughlin. “But many cannot begin to do so without knowing what the possibilities are. We hope this document and its accompanying activities can help to expand their thinking.”

The PCC also describes various “stages” of progress for educators. For example, in acquiring “core technology skills,” an educator might be at stage one: Entry — educators, students and the community are aware of the possibilities technology brings, yet learning, teaching and the system remain relatively unchanged by technology. Hopefully, the skills described by the PCC will lead that educator to Stage Two: Adaptation; and ultimately, Stage Three: Transformation, in which technology becomes a catalyst for significant changes in teaching learning practices.

The PCC is available in several formats. The first is the print publication described here. The second is the Web site, which will be dedicated to updating and evaluating progress with the PCC. And the third is an assessment tool, available both in print and online. The assessment tool is a matrix on which educators can plot their progress in various levels of technology integration and a tool to support the professional development planning process. The assessment tool consists of five parts:

  1. 20-question survey assessing educators’ individual levels of comfort with technology.
  2. A more in depth survey with at least 15 items per area which provides a more specific picture of areas of need.
  3. Database of “advice essays” linked to the survey. Each advice essay corresponds to the levels of comfort described in the survey and recommends ways for educators to improve.
  4. Database of resources — Web sites, articles, books and training — deemed valuable to the levels of comfort described in the survey.
  5. Comprehensive reports. Reports are available both for individual teachers and for groups of teachers. Individual teachers can access comprehensive reports in each of 26 areas of competency. Professional developers working with groups of teachers can create “project groups” for whom they can develop summary reports for the group or for any subgroup within the project. The assessments can be taken multiple times and progress can be charted over time for individuals and groups.

II  Read the following passage and answer the questions given below:

[3 x 2 = 6 marks]

 

Horror gripped the heart of the World War I soldier as he saw his lifelong friend fall in battle. Caught in a trench with continuous gunfire whizzing over his head, the soldier asked his lieutenant if he might go out to bring his fallen comrade back. “You can go,” said the Lieutenant, “but I don’t think it will be worth it. Your friend is probably dead and you may throw your own life away.” The Lieutenant’s words didn’t matter, and the soldier went anyway. Miraculously he managed to reach his friend, hoist him onto his shoulder, and bring him back to their company’s trench. As the two of them tumbled together to the bottom of the trench, the officer checked the wounded soldier, then looked kindly at his friend. I told you it wouldn’t be worth it,” he said. “Your friend is dead, and you are mortally wounded.” “It was worth it, though, sir,” the soldier said. “How do you mean, `worth it?’ ” responded the Lieutenant. “Your friend is dead!” “Yes sir,” the soldier answered. “But it was worth it because when I got to him, he was still alive, and I had the satisfaction of hearing him say, `Jim, I knew you’d come.’ ”

 

  1. What is the meaning of the expression ‘You may throw your own life away’?
  2. What does the phrase ‘mortally wounded’ mean?
  3. Why did the lieutenant warn the soldier not to go out to help his friend?

[10 x 1 = 10 marks]

 

I have a friend named Ravi who owns a college. He has let me use his college to conduct a programme in order to raise money for visually challenged students. He is so helpful to students because he feels that this is the time student’s dream and work towards their future. By saying so he started narrating an incident from Ravi’s life.

 

It all goes back to Ravi’s college days. He was the son a watchman in a reputed college. Since he went to see his father quite often in the college, so he was much attached to the college. By sheer hard work, he entered high school. When he was in the final year, he was asked to write an assignment about what he wanted to be and do when he grew up. “That night he wrote a seven-page assignment describing his goal of owning a college. He wrote about his dream in great detail and handed over to the teacher. Two days later he received his paper back. On the front was a large red F, which meant ‘fail’, with a note that read, “See me after class.” Ravi with his dream went to see the teacher and asked, “Why did I fail?” The teacher said, “This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. You have no resources. Owning a college requires a lot of money. You have to buy the land, erect giant buildings and above all, you have to pay a huge amount for the teachers every month. There is no way you could ever do it.” Then the teacher added, “If you would rewrite this paper with a more realistic goal, I will reconsider your grade.”

 

The boy went home and thought about it long and hard. He asked his father what he should do. His father said, “Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.” “Finally, after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, “You can keep the ‘F’ and I will keep my dream.” He still has the school paper framed safe on the wall and the mind.

 

  1. Ravi was selfish
  2. The Assignment changed his life
  3. Ravi belonged to a rich family
  4. Teacher discouraged Ravi
  5. Ravi loved his father
  6. Ravi rewrote the assignment
  7. Teacher scolded Ravi
  8. Ravi forgot the past
  9. Grade mattered much to Ravi
  10. The assignment is still with Ravi

 

 

IV Five stories are given. Neither title nor space is given for each story. Read them carefully and write appropriate titles for the five stories. In addition, read the following questions and write the answers.

[Title: 5 x 1 = 5 marks]

The five anecdotes

George Washington shocked his general one morning by merely being a gentleman. It seems Washington and his general were talking   together when a slave   passed.  “The coloured man paused, tipped his hat and said, “Good morning, your majesty”. Immediately Washington removed his hat, bowed and answered, “Good morning to you and I hope you have a pleasant day.” After a moment of shocked silence, the general asked, “Why did you bow to a slave?” Washington smiled and replied, “I would not allow him to be a better gentleman than I.” Oscar Wilde once passed by a flower shop. He asked the flower girl to pack all the flowers for him. She thought that he was a rich costumer on his way to some grand wedding! As he paid the bill the overjoyed flower seller asked him where she should deliver the basket. “Throw them away. Their faded look bleeds my sensitive heart.” So saying he went on his way. A disciple said to Mohammed, “Master, my six brothers are all asleep, and I alone have remained awake to worship Allah.” Mohammed replied, “And you too had better been asleep, if your worship of Allah consists of accusation against your brethren.” A boy was flying a kite with his father and asked him what kept the kite up. Dad replied, “The string.” The boy said, “Dad, it is the string that is holding the kite down.” The father asked his son to watch as he broke the string. Guess what happened to the kite? It came down. A boy was drowning in a river and he shouted for help. A man passing by jumped in the river and saved the boy’s life. As the man was leaving the boy said, Thank-you.” The man asked, “For what?” The boy replied, “For saving my life.” The man looked into the boy’s eyes and said, “Make sure when you grow up that your life was worth saving.”

 [Questions: 5 x 3 = 15 marks]

The painter caught the dumb mouth,

Fixed wide, in a man out walking

Down a road. One moment past,

Pleasantly, he was musing,

With the sun shining south

Behind him. Air and hill

Were drawn together

In blue and green paste

When the painted mouth is stilled .

Afflicted by knottier

Pigment, the eye, off-guard,

Suffers and goes mad,

In rigor mortis.
