ASSIGNMENT 1 CLASS –X

SUBJECT- ENGLISH TOPIC- COMPREHENSION

Name:_______ Class& Sec:____________ Roll No.___

Read the passage given below and answer the questions that follow:

1. Have you ever failed at something so miserably that the thought of attempting to do it againwas the last thing you wanted to do?

2. If your answer is yes, then you are ‘’ not a robot”. Unlike robots, we human beings have feelings,emotions and dreams. We are all meant to grow and stretch despite our circumstances and ourlimitations. Flourishing and trying to make our dreams come true is great when life is going ourway. But what happens when its’s not? What happens when you fail despite all of your hardwork? Do you stay down and accept the defeat or do you get up again again until you are

2

satisfied? If you have a tendency to preserve and keep going then you have what experts call, grit.

3. Falling down or failing is one of the most agonizing, embarrassing and scariest human experiences. But it is also one of the most educational, empowering and essential parts of living a successful and fulfilling life. Did you know that perseverance (grit) is one of the seven qualities that have been described as the keys to personal success and betterment in society? The other six are: curiosity, gratitude, optimism, self-control, social intelligence and zest. Thomas Edison is a model for grit for trying 1,000 plus times to invent the light bulb. If you are reading this with the lights on in your room, you know well how he succeeded. When asked why he kept going despite his hundreds of failure, he merely stated that what he had been not failures. They were hundreds of ways not to create a light bulb. This statement not only revealed his grit but also his optimism for looking at the bright side.

4. Grit can be learned to help you become more successful. One of the techniques that helps is mindfulness. Mindfulness is a practice that helps the individual stay in the moment by bringing awareness of his or her experience without judgement. This practice has been used to quiet the noise of their fears and doubts. Through this simple practice of mindfulness, individuals have the ability to stop the self- sabotaging downward spiral of hopelessness, despair and frustration.

5. What did you do to overcome the negative and self- sabotaging feelings of failure? Reflect on what you did and try to use those same powerful resources to help you today.

Read the following passage carefully.

1. Snow- clad mountains, opal- blue lakes and shimmering peaks, all these make the Himalayas look like the most romantic place on earth. The death of Lance Naik Hanumanthappa has, however, brought into sharp focus the difficult conditions under which our soldiers function to protect our borders.

2. The life of soldiers stationed at Siachen is extremely tough. For drinking water, they have to break ice from the glacier; boil it and drink it. There is one person assigned to keep the water warm at every moment of the day. The main task of the infantry stationed in the Siachen area is to hold the ground and man the post. To show their physical presence is important to keep the enemy at bay.

3. In the icy mountains it is constant battle with the climate. Keeping themselves healthy is another important aspect of their daily living. Picking up supplies that are air dropped to them and shoveling ice off their tents is a crucial part of their survival routine.

4. That is perhaps why Rashtriya Military School the nurturing grounds of future soldiers, send students on an expedition to the Siachen Glacier every academic year. These young cadets get to make the long arduous task up the snow- clad battle ground under the guidance of experienced army personnel, to truly understand what it means to be on the icy borders between India and Pakistan.

5. This gives a rare opportunity to students because the Siachen remains out of bounds for most armed personnel. It takes a lot of courage to face the situation there. Oxygen levels are low, there are steep ice walls to climb in sub- zero conditions and the high wind make it nearly impossible to walk. O ne has to be mentally strong to cope up with these extreme and hostile conditions.

6. There are many factors in the selection of candidates: physical endurance and leadership skills. Also, he must have a cheerful disposition as team work is important. They must also be able to speak with clarity.

7. This experience is an on- job training ground for students as they get an insight into the situation there. First hand experience of life in Siachen and survival skills in tough conditions prepare them for their future roles. They interact with officers and get a feel of life in the armed forces. Patriotic fervor, service to the nation- these attributes become part of their mindset. When they come back from the trek, a marked difference in their personalities can be seen. It is a great learning experience in many ways. It motivates future leaders to join the Army.

1. All of us do some kind of work toward off starvation or to gain sufficient material wealth with a view to maintain the standard of living which our physical and intellectual power have helped us to reach. But there is another kind of work which is completely divorced from the burdensome process of our livelihood and which is undertaken for the sake of amusement or interest or the direction of our surplus stores of energy in some new and useful channels of refined tastes. This delightful occupation combining work with pleasure or hobby, as it is properly termed, calls for the application of our highest faculties and gives proper form to our healthy instincts, purposeful habits and disciplined behavior. In our carefree and vacant hours, it allows these faculties to perform their natural functions and to display their instinctive greatness. We devote

7

our leisure to the pursuit of this pleasant task and derive advantages which compares favourably with those we obtain from the bread- earning routine of our daily life. Hobbies widen the sphere of our cultural activities, give refinement to our tastes and show us the path that leads to our systematic mental and moral development. Our tendencies and inclinations also find in them an outlet for a healthy and progressive expression.

2. A hobby is a favourite subject or occupation that is not one’s main business. In this age of machinery which has taken upon itself most of the laborious duties of physical exertion formally performed by man, than creating for him pleasant intervals of rest and leisure, it should not be difficult for him to devote some time to the pursuit of a new interest that can add some charm, colour or zest to his life. The spare time must not be fritted away in idleness or spent on such work as overtaxes one’s mind and body after one has performed one’s normal functions for the day. The occupation, banishes the drabness of routine work and produces a feeling that life is both charming and meaningful.

3. The choice of hobbies, like the choice of books, purposes of reading, is not an easy task. Some hobbies demand a little guidance from experienced persons. Our sudden attachment to them without the backing of this preliminary knowledge may result in wasting of our resources of time and money, and in the end compel us to abandon them. Some hobbies are rather expensive, and therefore beyond the means of ordinary people who can ill- afford to spend large sum of money on them. Also a few are incompatible with our temperament and taste. We must not, therefore, allow the glamour of certain hobbies to binds to their reality, however tempting they may appear to us, nor should we begin to cherish them thoughtlessly because we find other people so devotedly attached to them. In the first flush of enthusiasm many have rushed into unsuitable hobbies only to find themselves turning away from them in a state of great disillusionment. In a few rare and exceptional cases a sudden instinctive choice of some hobbies sometimes prove to be the right one. We must not, however, forget that tinkering with a hobby is a joyless and wasteful process, unattended by any appreciable gains. Scattered interest in half a dozen or more odd hobbies is also not a desirable end.

Answer the following questions briefly:

(i) What is a hobby? ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________

(ii) What are the advantages of hobbies? ___________________________________________________________________________ ___________________________________________________________________________

Read the following passage carefully.

1. Do you remember the last time you laughed out loud? For most of us laughing out loud is an uphill task. More often than not people think that they have no time to laugh. There are more important things to do. But if you ask Jean Legget, the Canadian founder of Bootcamp she’ll say you do not have anything more important to do than just laugh. Says Sudha Chandra, who attended a Bootcamp: ‘My life was joyless. Hiring a laughter coach changed my perspective towards life. I learnt to record my emotions and ensured that the four elements of joy- dancing, laughing, singing and playing – helped to build an emotional reserve.’

2. The cynic in us may still think it is an exaggeration, but the fact is that we can be taught to laugh more. Neuroscientist Jodi Deluca says it doesn’t matter why you laugh. Even in small doses, laughter improves the quality of life. You can condition people to feel more positive as laughter opens up the mind and frees the creative juices. It makes us more receptive to new ideas. The New York- based laughter coach Beth Bongar says that since our everyday lives are full of stresses, in her classes on laughter she uses the ‘gibberish’ technique where everyone laughs by using gibberish sounds. Such playful exercises help to reduce inhibitions and shyness and convert simulated laughter into unconditional laughter.

3. According to the greatest laughter therapists laughter is a cathartic process which helps rebalance the chemistry of emotions which can be a keynote for healing. Several researchers on the benefits of laughter in Japan have shown that laughter therapy is an efficient, low- cost, medical treatment that cuts health costs. According to their findings laughter is a stimulant that triggers energy inside a person’s DNA, potentially helping to cure disease. When we are laughing with other people, we share a sense of connectedness which in turn reduces loneliness. Says comedian Vir Das: ‘When 3000 people laugh at me during my performance, even if I’ve had a bad day, I feel joyful. Not everyone can be a comedian, but we can all learn to be more joyful.’

Read the following passage carefully

Everybody wants to succeed in life. For some success means achieving whatever they desire or dream. For many it is the name, fame and social position. Whatever be the meaning of success, it is success which makes a man popular.

All great men have been successful. They are remembered for their great achievements. But it is certain that success comes to those who are sincere.

12

Success has been man’s greatest motivation. It is very important for all. Success has a great effect on life. It brings pleasure and pride. It gives a sense of fulfillment. It means all round development. Everybody hopes to be successful in life. But success smiles on those who have a proper approach, planning, vision and stamina. A proper and timely application of these things is bound to bear fruit. One cannot be successful without cultivating these certain basic things in life. It is very difficult to set out on a journey without knowing one’s goals and purposes. Clarity of the objective is a must to succeed in life. A focused approach with proper planning is certain to bring success. Indecision and insincerity are big obstacles on the path of success.

One should have the capability, capacity and resources to turn one’s dreams into reality. Mere desire cannot bring you success. The desire should be weighed against factors like capability and resources. This is the basic requirement of success. The next important thing is the eagerness, seriousness and the urge to be successful. It is the driving force which decides the success. It is the first step on the ladder of success.

One needs to pursue one’s goals with all one’s sincerity and passion. One should always be in high spirit. Lack of such spirit leads to an inferiority complex which is a big obstruction on the path to success. Time is also a deciding factor. Only the punctual and committed have succeeded in life. Lives of great men are examples of this. They had all these qualities in plenty which helped them rise to the peak of success.

Hard labour is one of the basic requirements of success. There is no substitute for hard labour. It alone can take one to the peak of success. Every success has a ratio of five percent inspiration and ninety- five percent perspiration. It is the patience, persistence and perseverance which play a decisive role in achieving success. Failures are the pillars of success as they are our stepping- stones and we must get up and start again and be motivated.

2.1. On the basis of your reading of the passage, answer any four of the following questions in 30-40 words : (a) To whom does success come certainly? _____________________________________________________________________________________
