Story

Story of Appreciation

Story of Appreciation

One young academically excellent person went to apply for a managerial position in a big company.

He passed the first interview, the director did the last interview, made
the last decision.

The director discovered from the CV that the youth's academic
achievements were excellent all the way, from the secondary school until the postgraduate research, never had a year when he did not score.

The director asked, "Did you obtain any scholarships in school?" the
youth answered "none".

The director asked, " Was it your father who paid for your school fees?" The youth answered, "My father passed away when I was one year old, it was my mother who paid for my school fees.

The director asked, " Where did your mother work?" The youth answered, "My mother worked as clothes cleaner. The director requested the youth to show his hands. The youth showed a pair of hands that were smooth and perfect.

The director asked, " Have you ever helped your mother wash the clothes
before?" The youth answered, "Never, my mother always wanted me to study and read more books. Furthermore, my mother can wash clothes faster than me.

The director said, "I have a request. When you go back today, go and
clean your mother's hands, and then see me tomorrow morning.*

The youth felt that his chance of landing the job was high. When he went back, he happily requested his mother to let him clean her hands. His
mother felt strange, happy but with mixed feelings, she showed her hands to the kid.

The youth cleaned his mother's hands slowly. His tear fell as he did
that. It was the first time he noticed that his mother's hands were so wrinkled, and there were so many bruises in her hands. Some bruises were so painful that his mother
shivered when they were cleaned with water.

This was the first time the youth realized that it was this pair of hands that washed the clothes everyday to enable him to pay the school fee. The bruises in the mother's hands were the price that the mother had to pay for his
graduation, academic excellence and his future.

After finishing the cleaning of his mother hands, the youth quietly washed all the remaining clothes for his mother.

That night, mother and son talked for a very long time.

Next morning, the youth went to the director's office.

The Director noticed the tears in the youth's eyes, asked: " Can you tell me
what have you done and learned yesterday in your house?"

The youth answered, " I cleaned my mother's hand, and also finished
cleaning all the remaining clothes'

The Director asked, " please tell me your feelings."

The youth said, Number 1, I know now what is appreciation. Without my mother, there would not the successful me today. Number 2, by working together and helping
my mother, only I now realize how difficult and tough it is to get something done. Number 3, I have come to appreciate the importance and value of family relationship.

The director said, " This is what I am looking for to be my manager.
I want to recruit a person who can appreciate the help of others, a person who knows the sufferings of
others to get things done, and a person who would not put money as his only goal in life. You are hired.

Later on, this young person worked very hard, and received the respect of his subordinates. Every employee worked diligently and as a team. The company's performance improved tremendously.

A child, who has been protected and habitually given whatever he wanted, would develop "entitlement mentality" and would always put himself first. He would be ignorant of his parent's efforts. When he starts work, he assumes that every person must listen to him, and when he becomes a manager, he would never know the sufferings of his employees and would always blame others. For this kind of people, who may be good academically, may be successful for a while, but eventually would not feel sense of achievement. He will grumble and be full of hatred and fight for more. If we are this kind of protective parents, are we really showing love or are we destroying the kid instead?*

You can let your kid live in a big house, eat a good meal, learn. But when you are cutting grass, please let them experience it. After a meal, let them wash their plates and bowls together with their brothers and sisters. It is not because you do not have money to hire a maid, but it is because you want to love them in a right way. You want them to understand, no matter how rich their parents are, one day their hair will grow gray, same as the mother of that young person. The most important thing is your kid learns how to appreciate the effort and experience the difficulty and learns the ability to work with others to get things done.

Share this story to as many as possible...this may change somebody's fate.

Verbs

In English, a regular verb (EG: talk) has only two forms in the present tense; talk and talks
Singular Plural
1st person I talk we / you and I talk
2nd person you (singular) talk you (plural) talk
3rd person he, she, John, Lisa, the boy talks they / John and Mary / the girls talk
Only the verb to be has more than two forms in the present tense (am, is, are).
In the past tense, it is the only verb with more than one form (was, were). All other English verbs, regular and irregular, use just one form (talked, read, saw, etc.) for all persons.
In the future tense, English verbs show no subject-verb agreement whatsoever: I, you, he, we, they will do, speak, go, etc.

Auxiliary verbs

Auxiliary verbs are small verbs used to build verb chains.

Kate is speaking.

We had been asking.

She did like him once.

The auxiliary verbs are:

have when followed by a past participle:
e.g. have seen
be when followed by a present participle or by a past participle:
are working
are admired
do when followed by an infinitive:
do you think, do not think.
the modal verbs, which are generally followed by an infinitive:
will think, must be
Modal verbs

Modal verbs are auxiliary verbs that come in front of an infinitive (usually without to). They express such ideas as possibility, willingness, prediction, speculation, deduction, necessity and habit.

He must be angry

I can’t understand.

You ought to tell us.

Here are the main modal verbs:

will/would

may/might

dare

shall/should

must

need

can/could

ought

used to

Why be is always an auxiliary verb and possessive have sometimes is.

One of the main differences between auxiliary and main verbs is that auxiliaries are used in questions like Are you listening? and in negative sentences like You aren't listening. If we apply this as a test for auxiliary verbs, then other uses of be should also count as auxiliaries:

They are happy. Are they happy? They aren't happy.
He is your friend. Is he your friend? He isn't your friend.
It was here. Was it here? It wasn't here.
The same applies, for some people, to the verb have which means 'possess':

She has enough money. Has she enough money? She hasn't enough money.
Verb forms

The main verb forms (with examples from a regular verb) are these:

present tense

we walk

she walks



FINITE

past tense

I walked

imperative

Walk this way






NON-FINITE

present participle

I was walking

past participle

they have walked

infinitive

they can walk
they like to walk

Sometimes the word itself is the same – for example, walk can be present, infinive or imperative. But it’s important to be able to identify the different forms in use.

These six forms belong to two major groups, which play an important part in English grammar:

The present, past and imperative forms are finite.
The participles and the infinitive are non-finite.
Finite and non-finite verbs

If an ordinary sentence contains just one verb, this verb will be finite. (Why 'finite'?)
This is [finite] a finite verb.

In a verb chain, the first verb in the chain is almost always finite, and the other verbs are always non-finite.
They have [finite] looked [non-finite] at it

The finite verb in a clause defines the way the clause works. It gives key information about:

who is doing the thing - i.e. the subject:
e.g. They have ... but: She has ...
and when it is being done - i.e. the tense:
e.g. They have ... but: They had ...
Non-finite verbs are not restricted in these ways, though they are restricted in other ways. For example, the infinitive have can be used for any time and any subject:

He seems to have a cold. (present time, singular subject)

They seemed to have colds. (past time, plural subject)

Omission of Prepositions

Cases where Prepositions are omitted

We do not normally use prepositions of time (on, in, at etc) before words like last, next or this.


I met him last Sunday. (NOT I met him on last Sunday.)
I met him on Sunday.
We may discuss it next time. (NOT We may discuss it at next time.)

The use of preposition is optional in the following sentences.

I was here (in) the December before last.
The visited us (on) the day before yesterday.
She came here (in) the previous summer.
We waited there (for) two hours.

Different prepositions
Some words which have slightly different form and meaning take different prepositions after them.

Examples are: desire for but desirous of; confidence in but confident of

I have no desire for name or fame.
She is desirous of finding a job.
I have no confidence in his ability to perform the task.
I am confident of success in the examination.

More examples are given below:

According to but in accordance with;
Sensible of but insensible to;
Affection for but affectionate to;
Ambition for but ambitious of;
Fond of but fondness for;
Neglectful of; not negligent in;
Dislike to not liking for;
The prepositions at / on / in are not normally used in expressions of time beginning with next, last, this, that, one, any, each, every, some and all.

See you next week. (NOT See you in the next week.)
I am free this evening. (NOT I am free in this evening.)
You can come any time. (NOT You can come at any time.)
I worked all day. (NOT I worked on all day.)
Let’s meet one day. (NOT Let’s meet on one day.)
These prepositions are not used before yesterday, the day before yesterday, tomorrow or the day after tomorrow.

She is coming tomorrow. (NOT She is coming on tomorrow.)
I met him yesterday. (NOT I met him on yesterday.)


Also note that prepositions are dropped in questions beginning with what / which + expression of time.

What time is she arriving? (NOT At what time is she arriving?)
What day is the conference? (NOT On what day is the conference?)
She grew up —————– Canada. (in/on)

2. It is very hot ——————- the center of the earth. (in/at)

3. Turn right ——————– the next corner. (in/at)

uses of articles

In English, knowing when to use 'a' or 'the' can be difficult. Fortunately, there are rules to help you, but you need to know what type of noun you are using.

Grammar rule 1

When you have a single, countable English noun, you must always have an article before it. We cannot say "please pass me pen", we must say "please pass me the pen" or "please pass me a pen" or "please pass me your pen".

Nouns in English can also be uncountable. Uncountable nouns can be concepts, such as 'life', 'happiness' and so on, or materials and substances, such as 'coffee', or 'wood'.

Grammar rule 2

Uncountable nouns don't use 'a' or 'an'. This is because you can't count them. For example, advice is an uncountable noun. You can't say "he gave me an advice", but you can say "he gave me some advice", or "he gave me a piece of advice".

Some nouns can be both countable and uncountable. For example, we say "coffee" meaning the product, but we say "a coffee" when asking for one cup of coffee.

Grammar rule 3

You can use 'the' to make general things specific. You can use 'the' with any type of noun – plural or singular, countable or uncountable.

"Please pass me a pen" – any pen.
"Please pass me the pen" – the one that we can both see.

"Children grow up quickly" – children in general.
"The children I know grow up quickly" – not all children, just the ones I know.

"Poetry can be beautiful"- poetry in general.
"The poetry of Hopkins is beautiful" – I'm only talking about the poetry Hopkins wrote.

More uses of articles in English

Rivers, mountain ranges, seas, oceans and geographic areas all use 'the'.
For example, "The Thames", "The Alps", "The Atlantic Ocean", "The Middle East".

Unique things have 'the'.
For example, "the sun", "the moon".

Some institutional buildings don't have an article if you visit them for the reason these buildings exist. But if you go to the building for another reason, you must use 'the'.

"Her husband is in prison." (He's a prisoner.)
"She goes to the prison to see him once a month."

"My son is in school." (He's a student.)
"I'm going to the school to see the head master."

"She's in hospital at the moment." (She's ill.)
"Her husband goes to the hospital to see her every afternoon."

Musical instruments use 'the'.
"She plays the piano."

Sports don't have an article.
"He plays football."

Illnesses don't have an article.
"He's got appendicitis."
But we say "a cold" and "a headache".

Jobs use 'a'.
"I'm a teacher."

Countries
We don't use 'a' if the country is singular. "He lives in England." But if the country's name has a "plural" meaning, we use 'the'. "The People's Republic of China", "The Netherlands", "The United States of America".

Continents, towns and streets don't have an article.
"Africa", "New York", "Church Street".

Theatres, cinemas and hotels have 'the'.
"The Odeon", "The Almeira", "The Hilton".

Abbreviations use 'the'.
"the UN", "the USA", "the IMF".

We use 'the' before classes of people.
"the rich", "the poor", "the British".

Tips for Gd

Be Your­self. You can only act as your­self. All oth­ers acts fail, or at least these exer­cises are attempt­ing to fail such acts. It is eas­ier con­vers­ing being you.

b) Take time to orga­nize your thoughts. Dur­ing the dis­cus­sion there will a lot many points. You might be nod­ding your head to many of them. But do not pitch in to say any­thing as soon as it is put on table. Think of the pros and cons. Take time to orga­nize your thoughts and put them across once you are confident.

c) The panel is lis­ten­ing to you always. Do not try to con­vince them or look for an acknowl­edg­ment. It is the group which mat­ters here-stick to them.

d) Seek clar­i­fi­ca­tions if you have any doubts regard­ing the sub­ject, before the dis­cus­sion commences.

e) First impres­sions speak a lot of you. So make sure to show the right ges­tures, the right words and more impor­tantly the right spirits.

f) Never try to show your dom­i­nance. Be assertive, speak your­self and let oth­ers speak as well.

g) Don’t lose your tem­per. Remem­ber every­one is a par­tic­i­pant there. They are putting across their point. Be log­i­cal and break down your answer to accept­able chunks. This will help you in confrontations

h) Show your lead­er­ship skills. Build­ing a con­sen­sus needs lead­er­ship skills. Steers the dis­cus­sion in right track also try to make all par­tic­i­pants speak-this would help in con­sen­sus building.

i) Any out­ra­geous act is sure to seize inter­est but least expects them to sus­tain that interest.

I hope this series of arti­cles on GD helped you up your ante for real life bat­tles. Best of luck!

Report of the Voluntary Service Organization on the help extended to Flood Victims
Nellore:
This is a report on the help extended to the Flood victims recently in Nellore by the Voluntary Services Organization.
Several areas in and around Nellore were affected by floods. Mypadu was severely affected due to the flood. The people in the affected area became homeless and some of the people lost their lives. Many of them were affected with water born diseases. Many people were starving for basic requirements like food, clothes and shelter. Media covered this entire scene and telecasted on the televisions. As a result many government organizations and Red Cross organizations came forward and extended a helping hand.

Thousands of local palm thatch homes were swept away by the storm and infrastructure was damaged to a great extent. Power lines were down, roads flooded and communication links were severed in many areas. Many people in the near by areas were evacuated and were provided shelter in safer places. The cyclone shelters built by the Red Cross Organization in Tamil Nadu, Andhra Pradesh and Orissa rescued these people. This saved many lives by preventing people from epidemic diseases.
The Voluntary Service Organization Operations unit started to help the victims of the recent floods. Priorities were given to people with injuries and food water and shelter were provided to the thousands of people who were homeless. It was run by Students Volunteer Organization who tried to help as many victims as possible. They all joined their hands with government officials in helping the victims by shifting those victims to the safer places first. As many people as possible were helped get insurance for their houses and reconstruction of their houses at the earliest.

4. a. Write an essay in about 400- 500 words on “Advantages and disadvantages of Vegetarian and non-vegetarian food” 10m


Ethical:

Food has a major role to play in our fitness. Researchers have repeatedly proved that healthy food is the main key to good health. By healthy food, it means the food that is nutritious and full of essential vitamins and minerals. Green leafy vegetables and fresh fruits are the best reserves of vital nutrients that safeguard our body against many diseases. Most importantly, water is the most essential requirement of our body. Be sure to drink at least eight to ten glasses of water daily to make our self plump and soft.
Before moving further, let us get started with some important foods that will not only make us healthy, but will also make one look young and radiant. Beans, pumpkin, oranges, and yoghurt are few of the many vegetarian foods that are sure to give us an endless aura. After all, ravishing beauty is what that comes from within. One can surely enhance one’s outer looks by expensive make-ups, but what and how he/she eats reflect the real beauty.

No specific food is responsible for specific health ailments. These super foods give a wide coverage for a variety of ailments including diabetes, cancer, hypertension, and cardiovascular diseases. They also help us to keep a check on your weight and make one look beautiful and glowing.
Let us take a look at some other super foods. Animal food is rich in proteins and proteins all know help in the wear and tear of our body. Fish, eggs, and animal meat keep one in a great shape.
Both diets are healthy if done correctly. And the pros and cons for each are probably similar. Meat is rich in protein, iron, vitamin B1 and niacin. Non-vegetarian food is a good source of excellent protein.
One of the advantages to the vegetarian diet is that it tends to be low in fat and cholesterol. As a result, a vegetarian diet can help one avoid heart problems and even cancer. However, one may also find that he/she is missing some important vitamins and minerals on a strictly vegetarian diet.

Advantages of vegetarian foods are:

• They are easily chewable, especially for the elderly who have lost their teeth.
• Many elderly feel that vegetarian food is more easily digestible.
• Vegetarian foods are cheaper than non-vegetarian foods.
• Some vegetables can be eaten raw preventing the loss of nutrients while cooking.
• Vegetarian foods do not contain as much fat as non-vegetarian foods.
Thus, Vegetarians should take care to include soya beans, groundnuts, lentils, mushrooms and so on to get a sufficient supply of proteins.

Advantages of Non-Vegetarian foods are:

• Non-vegetarian foods are rich in protein of high biological value and in Vitamin B complex, especially B12 which is not available in plant foods.
• Fish, especially the small varieties are a rich source of calcium.
• Egg-white is good source of protein and easily digested.

The incidence of high BP, Heart disease, Obesity and high cholesterol levels is found to be greater among non-vegetarians. Elders who suffer from these problems should reduce the intake of fleshy foods in their diet. Egg-white and most varieties of fish contain less fat, but are rich in protein, vitamins and minerals.
Vegetarian or non-vegetarian, the decision depends on various factors such as cultural or dietary habits of the family, personal preference, taste and avoidance of certain foods for health reasons. Whatever the case, a well-balanced diet supplying proteins, fats, carbohydrates, vitamins and minerals should be taken.
