ENGLISH WORKSHEET

CLASS- XI (2017-2018)

_____________________________________________________________________________________

Q.1 Read the following passage carefully and answer the questions that follow.

1. The tests of life are its plus factors. Overcoming illness and suffering is a plus factor, for it moulds character. Steel is iron plus fire; soil is rock plus heat. So let’s include the plus factors in our lives.

2 Sometimes, the plus factor is more readily seen by the simple-hearted. Myers tells the story of a mother who brought into her home - as a companion to her own son - a little boy who happened to have a hunchback. She had warned her son to be careful not to refer to his disability,and to go right on playing with him as if he were like any other boy.

3 The boys were playing and after a few minutes, she overheard her son say to his companion: "Do you know what you have got on your back?" The little boy was embarrassed, but before he could reply, his playmate continued : "It is the box in which your wings are and some day God is going to cut it open and then you will fly away and be an angel."

4 Often it takes a third eye, or a change in focus, to see the plus factor. Walking along the corridors of a hospital recently where patients were struggling with fear of pain and tests, I was perturbed. What gave me fresh perspective were the sayings put up everywhere, intended to uplift. One saying made me conscious of the beauty of the universe in the midst of pain, suffering and struggle. The other saying assured me that God was with me when I was in deep water and that no troubles would overwhelm me. 5. The import of those sayings also made me aware of the nether springs that flow into people's lives when they touch rock bottom or when they feel lonely, or even deserted. The nether springs make recovery possible, and they bring peace and patience in the midst of pain and distress.

6. The forces of death and destruction are not so much physical as they are psychic and psychological. When malice, hate and hard-heartedness prevail, they get channelled as forces of destruction. Where openness, peace and goodheartedness prevail, the forces of life gush forth to regenerate hope and joy.

7. The life-force is triumphant when love overcomes fear. Both fear and love are deep mysteries, but the effect of love is to build whereas fear tends to destroy. Love is often the plus factor that helps build character. It helps us to accept and to overcome suffering. It creates lasting bonds andits reach is infinite.

8. It is true that there is no shortage of destructive elements, forces and people who seek to destroy others and in the process, destroy themselves – but at the same time, there are signs of

love and life everywhere that are constantly enabling us to overcome setbacks. So let's not look only at gloom and doom – let’s seek out positivity and happiness; because it is when you seek, that you will find what is waiting to be discovered.

1.1 On the basis of your reading of the above passage, make notes on it, using headings and sub-headings. Use recognizable abbreviations, wherever necessary.

1.2 Write a brief summary of the above passage.

Q2. You participated in a career counselling organised by Career India. You had the opportunity of listening to professionals from various fields like food technology, fashion technology, media management etc. Write a report of the programme for Career Times in about 150-200 words.

Q3. The following passage has not been edited. There is one error in each line. Identify the wrong word and write it with the correct word in your answer sheet.

Teenage is a spring of man’s life a) _______ _______

It is perceive as the most joyful b)_______ _______

Everything smell of freshness and fitness. e) _______ _______

There are aspiration and expectancy in life, f)_______ _______

But, the teenagers of today are live g) _______ _______

under the pressure of a competitive world. h)_______ _______

Q4. Change the direct speech to reported speech:

1. “I've never been to Brazil.”

2. “She has visited Paris three times.”

3. “He has read ‘War and Peace’.”

4. “I haven't seen Julie for ages.”

5. “He hasn't been to school this week.”

6. “We haven't seen ‘The Lord of the Rings’.”

7. “They've eaten in a lot of different restaurants.”

8. “I've never tried skateboarding.”

9. “Lucy has drunk six cups of coffee today.”

10. “Mr Black has written three books.”

Q5. Answer the following questions based on your reading of the novel ‘Canterville Ghost’.

i)What idea do you form of Lord Canterville’s character from your study of ‘The Canterville Ghost’?

ii)How did the twins trouble the ghost?

iii)The novel Canterville Ghost is full of humour. Justify.

iv)People who have a practical outlook often face adversities boldly. Justify.

v)Compassionate human beings understand the others and help to emancipate them. Justify the statement with reference to the character Virginia.

CLASS-XI SUBJECT- COMPUTER SCIENCE

Wholemeal Breads is a market that distributes and sells food products, such as bread and other confectionery items. The store sells bread in the following three sizes:

Big bread Medium Bread Small Bread

For all preceeding categories, the shop offers the following unit price to its customers:Big bread for Rs 15Medium bread for Rs 8.Small Bread for Rs.5The market has a separate shops for retail and wholesale buying. The customers who buy bread in wholesale get 20% discount on the total price. The retails buyers do n’t get any discount.An entry is made for each category of bread in stock every morning. When a customer arrives, the choice for the purchase is recorded .If the purchase is made, the total amount that the customer must pay is calculated. You are assigned the task to automate the preceding steps by creating a C++ program.

Write a program that generates the following:-Main Menu1. Retail Buyer2. Wholesale buyer

Enter the category (1-2)Retail buyer1. Enter the number of big Breads:2. Enter the number of medium Breads:3. Enter the number of small Breads:Amount for big breads:Amount for big breads:Amount for big breads:Amount payable:Wholesale buyer4. Enter the number of big Breads:5. Enter the number of medium Breads:6. Enter the number of small Breads:Amount for big breads:Amount for big breads:Amount for big breads:Discount:Amount payable:

Planning and ImplementationCreate a program for the above requirements by first planning i.e. (Algorithm) and then writing code. Implement the program using C++ language.

Identify the variable to be defined. Identify the data type of the variables. Identify the mechanism for displaying and accepting the user input. Program should be menu driven Implement the program. Execute the program. Enter the sample data and test the program.
