The Legend of Jaswantgarh Summary in English and Tamil

Jaswant Singh Rawat was an Indian soldier, the place Jaswantgarh in Arunachal Pradesh gets its name from him. The legendary story, “The battle of Nauranang”, handed down through the ages of Nauranang is inspiring and records the valor and patriotism of Jaswant.

ஜஸ்வந்த் சிங் ராவட் என்பவர் இந்திய இராணுவ வீரர். அருணாச்சலபிரதேசத்திலுள்ள ஜஸ்வந்த்க ர் என்ற இடம் இவரது பெயரால் உருவானது. ‘நவ்ரானங் யுத்தம்’ என்ற வரலாற்று கதை காலங்காலமாக கூறப்பட்டு, ஜஸ்வந்த்தின் வீரத்தையும், தேசபக்தியையும் பதிவு செய்திருக்கிறது.

There was a war between India and China in the year 1962. In the final part of the war, Nauranang was the last stand of the Indian army against the Chinese army. The battle started on 17th November 1962 and continued for seventy-two hours. At 5.00 am, in the Eastern Himalayas, the Chinese army attacked the lonely Indian post in Nauranang. Knowing that the Chinese army was stronger, the Indian soldiers on the post were ordered to retreat and regroup. But, Jaswant did not leave his post and decided to continue the fight to hold the Chinese until the reinforcements arrive.

1962-இல் இந்தியாவுக்கும் சீனாவுக்கும் இடையே போர் நடந்தது. போரின் கடைசி கட்டத்தில், நவ்ரானங்-இல் இந்திய ராணுவமும் சீன ராணுவமும் நிலை கொண்டிருந்தன. 17 நவம்பர் 1962 அன்று தொடங்கிய யுத்தம்
72 மணி நேரம் நீடித்தது. காலை 5 மணிக்கு கிழக்கு இமய மலைப்பகுதியில், நவ்ரானங் இல் தனித்திருந்த இந்திய முகாமை சீன இராணுவம் தாக்கியது. சீன இராணுவம் அதிக பலம் பெற்றிருந்ததை அறிந்த பிறகு, இந்தியப் படைகள் பின்வாங்க வேண்டுமென உத்தரவிடப்பட்டது. ஆனால் ஜஸ்வந்த் அந்த இடத்தைவிட்டு போகாமல், கூடுதல் படை வரும்
வரை தொடர்ந்து சண்டையிட தீர்மானித்தார்.

Two village girls named Sela and Nura helped Jaswant. They set up weapons at separate points. Jaswant taught the girls to fireguns. All three kept shooting on the Chinese army. Jaswant was running to different gun points and kept shooting. His intention was to give the Chinese army a perception that they are facing a huge Indian battalion. He did this for three continuous days. Jaswant and the girls had killed three hundred Chinese soldiers. The Chinese army decided to cut the food supply to the post.

சேலா, நூரா ஆகிய இரு கிராமப் பெண்க ள் ஜஸ்வந்த்க்கு உதவினர்.வெவ்வேறு இடங்களில் ஆயுதங்களுடன் நிலை கொண்டனர். அந்தப் பெண்க ளுக்கு துப்பாக்கி சுட ஜஸ்வந்த் கற்று கொடுத்தார். சீன இராணுவத்தின் மீது மூவரும் சுட்டுக் கொண்டிருந்தனர். ஒரு பெரிய இந்தியப்படையை சீன ராணுவம் எதிர்கொண்டுள்ளது என்று சீனர்கள் நினைத்து பயந்து ஓட வேண்டும் என்பது ஜஸ்வந்த்தின் திட்டமாக இருந்தது. அவர் இதனை மூன்று நாட்களுக்குத் தொடர்ந்து செய்தார். அவரும், அந்த இரு பெண்க ளும் 300 சீன இராணுவத்தினரை சுட்டுக் கொன்றார்கள். அவர் இருந்த இடத்திற்கு உணவு கொண்டு செல்லப்படுவதை நிறுத்த சீன இராணுவம் தீர்மானித்தது.

The Chinese soldiers caught the man, who brought food for the three. In the Chinese interrogation, the man told the truth that a single soldier was guarding the post. A single soldier and two village girls had fooled the Chinese. They were shocked and furious. They surrounded Jaswant Singh and launched a final attack.

இந்த மூவருக்கும் உணவை எடுத்துச் சென்ற ஒரு ஆளை சீன வீரர்கள் பிடித்தனர். அவனை விசாரித்தனர். ஒரே ஒரு இந்திய வீரர் மட்டுமே அங்கு இருப்பதாக அந்த ஆள் உண்மையைச் சொல்லிவிட்டான். ஒரு தனித்த இந்திய வீரரும், இரண்டு கிராமப் பெண்களும் சீனர்களை முட்டாள்களாக்கி ஏமாற்றியதை உணர்ந்த னர். இதனால் சீன வீரர்கள் அதிர்ச்சியும் கோபமும் கொண்டனர். அவர்கள் ஜஸ்வந்த்தை சுற்றி வளைத்து இறுதித் தாக்குதலை நடத்தினர்.

Jaswant shot himself as the Chinese were going to capture him. A grenade blast killed Sela. Nura, the tribal girl, was captured alive.
சீனர்களிடம் தான் பிடிப்படப்போவதை உணர்ந்த ஜஸ்வந்த் தன்னைத்தானே சுட்டுக் கொண்டார். ஒரு கையெறி குண்டு வெடித்து, சேலா கொல்லப்பட்டாள். நூரா என்ற பெண் உயிரோடு பிடிக்கப்பட்டாள்.

After the war, the commander of the Chinese army returned the brass bust of Jaswant. A war memorial with the brass bust was made to remember him and his service to the nation. All army personnel who pass through this memorial pay their respect to him.

யுத்தம் முடிந்த பிறகு, சீன போர்த்தளபதி, மார்பளவு உள்ள ஜஸ்வந்த்தின் பித்தளை சிலையை வழங்கினார். ஜஸ்வந்த் தேசத்திற்கு செய்த சேவையை நினைவுபடுத்தும் வகையில், அந்த பித்தளை சிலையுடன் ஒரு போர் நினைவகம் கட்டப்பட்டது. இந்த இடத்தைக் கடந்து செல்லும் எல்லா இராணுவ வீரர்களும், ஜஸ்வந்த்க்கு தங்கள் மரியாதையை
அளிக்கின்றனர்.

The Indian Army still treats him as a serving officer and awards him promotions. India awarded him the Mahavir Chakra. Jaswant may have died in battle that day, but he still lives in the memory of people in Jaswantgarh and the Indian army.

ஜஸ்வந்த் இறந்துவிட்டாலும் கூட, இந்திய இராணுவம் அவரை இன்னும் பணியிலுள்ள அதிகாரியாக கருதி, அவருக்கு பதவி உயர்வுகளைத் தந்து வருகிறது. இந்திய அரசு அவருக்கு மகா வீர் சக்ரா என்ற விருதை வழங்கியது. ஜஸ்வந்த் அன்று போரில் . இறந்திருந்தாலும், அவர் இன்றும் ஜஸ்வந்த்கர் இல் உள்ள மக்களின் நினைவிலும், இந்திய ராணுவத்தினரின் நினைவிலும் வாழ்கிறார்.

VI. Answer in detail:

Question 1.
What are the factors for food Spoilage?
Answer:
Food can be spoiled by factors like air and oxygen, moisture, light, micro-organisms, and temperature.
Air and Oxygen: When oxygen reacts with food contents, it produces changes in the colour and flavour of the food.
Moisture: Moisture keeps the food fresh. When the moisture is gone vegetables and fruits shrink. Due to evaporation, moisture loss occurs in foods like meat, fish and cheese. Enzymes: Enzymes break down the tissues and components of the food in different ways like oxidation, browning and ripening. So the food items decay.
Micro-organisms: Micro-organisms such as fungi, yeast and bacteria can grow well in low temperatures. They multiply in food and spoil them.
Light: Light produces colour changes and also vitamin loss.
Temperature: Sometimes the rise in temperature causes food spoilage.

Question 2.
Explain the different types of diseases.
Answer:
There are four main types of diseases. They are:

• Infectious diseases
• Hereditary diseases
• Physiological diseases
• Deficiency diseases.

a. Infectious diseases: Infectious diseases are caused by micro-organisms which invade our body and multiply inside them. These diseases are spread from one person to another. E.g. Common cold.
b. Hereditary diseases: Hereditary diseases are spread by abnormalities in the gene. These diseases are passed from parents to children. E.g. Heart disease.
c. Physiological diseases: Diseases which are caused due to malfunction of the body organs are called physiological diseases. E.g. Asthma.
d. Deficiency diseases: A diet which contains all essential nutrients in correct proportion is indispensable for maintaining good health. Deficiency in one or more of the nutrients causes various diseases. These are called deficiency diseases.

Question 3.
Write any 6 tips for fire protection and prevention.
Answer:

• Do not keep the inflammable materials like kerosene etc, near the gas stoves.
• In case of person’s clothes catching fire, cover the person with a thick blanket or carpet.

• If solid materials like wood catch fire, use water to put out the fire.
• If an electrical appliance catches fire, unplug the appliances and disconnect the electricity.
• Use proper fire extinguishers to put out the fire.

Question 1.
Write a note on parts of Plants.
Answer:
Parts of a plant

• A plant is made up of many different parts. The three main parts are the roots, the
  leaves, and the stem.
• Each part has a set of jobs to do to keep the plant healthy.
• The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground and carries the water and minerals to the leaves.
• The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.

Question 2.
Explain the methods of pollination.
Answer:

• Pollination by Wind (Anemophily): The flowers pollinated by wind are mostly small in size and do not have any attractive colour, smell and nectar. The pollen grains are non-sticky, dry, light and powdery. Hence, they are easily carried by the wind. E.g. Grass, Maize, Pine.
• Pollination by Water (Hydrophily): The flowers of water plants are not colourful and they have no nectar. Pollen grains of these plants have mucilaginous covering to protect them from getting wet. They float in water and reach the other plant. E.g. Vallisneria, Hydrilla, Zosteria.
• Pollination by Insects (Entamophily): This is the most common type of pollination in plants like sunflower, ladies finger, brinjal and pumpkin. Some flowers are large in size and they have a sweet smell. Some of these flowers produce nectar. They attract insects like butterflies and honey bees.

Question 3.

Answer:

• Sandy soil: It contains a greater proportion of big particles. They cannot fit closely together. Water can drain quickly through the spaces between the sand particles. So, sandy soils tend to be light, well aerated and dry.
• Clay soil: It contains a greater proportion of fine particles, packed tightly together. leaving little space for air. It can retain a lot of water in the tiny gaps between the particles. Plants like paddy grow well in this soil.
• Loamy soil: It Contains large and fine particles in almost same proportion. The best topsoil for growing plants is loam. It is a mixture of sand, clay and another type of soil particle known as silt. Silt occurs as a deposit in river beds. It has right water holding capacity for the growth of plants. Clay and loamy soil are suitable for growing wheat, gram and paddy.

The Farmer and his Daughters Summary in English and Tamil

In the village of Manipuram, there lived a wealthy farmer. He had three daughters. All his daughters were married and living their life happily. The farmer was getting old. He wanted to distribute his wealth to his daughters. But he wanted to know what responsibility he could give to each of his daughters. He called all his daughters and gave each of them a bag of millet. He asked them to use grains in the best way possible and then come back to him after one year.

மணிப்புரம் என்ற கிராமத்தில் ஒரு பணக்கார விவசாயி வசித்து வந்தார். அவருக்கு மூன்று மகள்கள் இருந்தனர். அவரது எல்லா மகள்களுக்கும் திருமணமாகி, அவர்கள் மகிழ்ச்சியாக வாழ்ந்து கொண்டிருந்தனர். விவசாயிக்கு வயதாகிக் கொண்டிருந்தது. அவரது சொத்தை தனது மகள்களுக்கு பிரித்துக் கொடுக்க விரும்பினார். ஆனால் ஒவ்வொரு மகளுக்கும் எந்த பொறுப்பை கொடுப்பது என அறிய விரும்பினார். தனது மகள்களை அழைத்து ஒவ்வொருவருக்கும் ஒரு பை நிறைய
தினை வகையைச் சேர்ந்த தானியத்தைக் கொடுத்தார். அந்த தானியத்தை சிறந்த முறையில் பயன்படுத்திவிட்டு, ஓர் ஆண்டுக்குப்பிறகு தன்னை வந்து பார்க்கச் சொன்னார் அவர்.

After one year the daughters came back to their father’s house. The farmer welcomed all of them.

ஓர் ஆண்டுக்குப் பிறகு அவரது மகள்கள் அவரது வீட்டிற்கு வந்தார்கள். அந்த விவசாயி | மூவரையும் வரவேற்றார்.

First, he called the elder daughter and asked about what she had done with the grains given to her. She replied, “Father, I fed those grains to flocks of birds that I saw on my way back to home.”

முதலில், தன் மூத்த மகளை அழைத்து, அவளுக்கு கொடுத்த தானியத்தை என்னசெய்தாள் என கேட்டார். “அப்பா, நான் என் வீட்டுக்குப் போகும் வழியில் நான் பார்த்த பறவைகளுக்கெல்லாம் உணவாக கொடுத்துவிட்டேன்”, என்று அவள்
பதிலளித்தாள்.

Then the father called the second daughter and asked the same. She replied,”Father, I thought those grains were sacred. So I mixed those with other grains kept for community food service. So that everyone could have it. After this, the third daughter came. The farmer asked her about the grains.

பிறகு அவர் இரண்டாவது மகளை அழைத்து அதே கேள்வியைக் கேட்டார். “அப்பா, நான் அந்த தானியங்கள் புனிதமானவை என்று நினைத்தேன். ஆகவே அதை மற்ற தானியங்களோடு கலந்து, சமுதாய உணவு சேவைக்காக கொடுத்துவிட்டேன். ப்பிட முடியும்”, என்றாள் அவள். இதன் பிறகு மூன்றாவது மகள் வந்தாள். விவசாயி அவளிடம் தானியத்தைப் பற்றி கேட்டார்.

She said, “Father, I don’t have those grains with me now. I need two bullocks and men to get the grains.” Father was confused and asked her, “Why do you need bullocks and men to bring the grains here?” The daughter smiled and replied “I sowed those grains and now it has grown as crops. So, I need a bullock cart and men harvest and bring back the grains.” Father was happy to know that she used the grains wisely.

அவள் கூறினாள், “அப்பா, இப்போது அந்த தானியங்கள் என்னிடம் இல்லை. தானியத்தைக் கொண்டுவர இரண்டு காளையுடனான மாட்டு வண்டியும், ஆட்களும் எனக்கு தேவைப்படுகிறது”. அவளது தந்தை குழப்பமடைந்து, “அந்த
தானியத்தை இங்கே கொண்டுவர எதற்காக உனக்கு மாட்டு வண்டியும் ஆட்களும் தேவைப்படுகிறது?”, என கேட்டார். அந்த மகள்புன்னகைத்தபடியே, “அந்த தானியங்களை to நான் வயலில் பயிரிட்டேன். இப்போது அவை பெருமளவில் வளர்ந்து பயிராகியுள்ளன. அதை அறுவடை செய்து, எடுத்து வர மாட்டு வண்டியும், ஆட்களும் எனக்குத் தேவை”, என்று
பதில் சொன்னாள். புத்திசாலித்தனமாக அவள் தானியத்தை பயன்படுத்தியதை அறிந்து, அவளது தந்தை மகிழ்ச்சியடைந்தார்.

Father found her apt and gave her the responsibility of the fields. He distributed his other wealth equally among the other two daughters.

அவளே தன் நிலங்களை பராமரிக்க தகுந்தவள் என அவளது தந்தை அறிந்து கொண்டு, வயல்களுக்கான பொறுப்பை அவளிடம் கொடுத்தார். தனது பிற சொத்துகளை சமமாக | பிரித்து இரு மகள்களுக்குக் கொடுத்தார்.

10th April: 10 ஏப்ரல் :
I am very eager to visit my grand parents’ village. I will meet my grand parents and cousins. I have packed my clothes and tab for playing video games. We will be travelling in a bus. I am so excited.

என் தாத்தா பாட்டியின் கிராமத்திற்குப் போக நான் வெகு ஆர்வமாக இருக்கிறேன். அங்கு என் தாத்தா பாட்டியையும், உறவினர்களையும் நான் சந்திப்பேன். வீடியோவில் விளையாட்டுக்களை விளையாட ‘டேப்’ எனப்படும் கருவியையும், எனது
உடைகளையும் எடுத்துக் கொண்டேன். நாங்கள் ஒரு பேருந்தில் பயணிப்போம். நான் மிகவும் உற்சாகமாக இருக்கிறேன்.

11th April:11 ஏப்ரல்:
Today we are travelling. Though it is summer, the weather is pleasant in the morning. There are numerous trees with yellow flowers on both sides of the road. There is greenery all around. There are many white cranes in the lush green paddy fields. The scarecrows have managed to scare away the crows in the fields. There is no traffic, noise and air pollution in the village.

இன்று நாங்கள் பயணம் செல்கிறோம். கோடைக்காலமாக இருந்தாலும், காலையில் வானிலை இதமாக இருக்கிறது. சாலையின்
இருபுறங்களிலும் எண்ணற்ற மரங்கள் மஞ்சள் மலர்களுடன் உள்ளன. சுற்று வட்டாரம் முழுதும் பசுமையாக இருந்தது. பசுமையான நெல்வயல்களில் பல வெள்ளை கொக்குகள் இருந்தன. வயல்களில் காகங்களை பயமுறுத்தி விரட்ட மனித உருவ பொம்மைகள் இருந்தன. வாகனப் போக்குவரத்து, இரைச்சல், காற்று மாசு என்று எதுவும் கிராமத்தில் இல்லை.

I get off the bus and run to meet my grandparents. They are deliahted to see me. The house is surrounded by many big trees. There are a few jackfruit, mango, neem, banana, pomearanate and coconut trees. The trees have abundant fruits. My grandfather has plucked some ripe mangoes for me. The mangoes are so juicy and sweet.

நான் பேருந்திலிருந்து இறங்கி, என் தாத்தா பாட்டியைச் சந்திக்க ஓடினேன். அவர்கள் என்னைப் பார்த்ததில் பெரு மகிழ்ச்சியடைந்தனர். பல பெரிய மரங்கள் வீட்டைச் சூழ்ந்து இருந்தன. சில பலா, மா, வேம்பு, வாழை, மாதுளை, தென்னை மரங்கள் இருந்தன. மரங்களில் அதிக அளவில் பழங்களும் இருந்தன. சில பழுத்த மாம்பழங்களை என் தாத்தா எனக்காக பறித்தார். மாம்பழங்கள் மிகவும் சாறுடனும், சுவையுடனும் இருந்தன.

12th April: 12 ஏப்ரல் :
I have woken up early today. I am out for a walk in the morning. The cool breeze is pleasing. The coconut palms are swaying lazily. The farmers are already in their fields. Some of them are cutting the crops and some of them are threshing the paddy. The air is filled with the sweet sound of birds singing in the trees and the bushes. The cuckoo’s song is perhaps the most enchanting.

இன்று நான் சீக்கிரமாக எழுந்துவிட்டேன். காலையில் வெளியே நடைபயிற்சிக்காக.சென்றேன். குளிர்ந்த காற்று இதமாக இருந்தது.
தென்னை, பனை மரங்கள் சோம்பலுடன் அசைந்து கொண்டிருந்தன. விவசாயிகள் ஏற்கனவே அவர்களது வயல்களில் இருந்தனர். அவர்களில் சிலர் அறுவடை செய்தனர். சிலர் கதிர் அடித்தனர். மரங்களிலும், புதர்களிலும் இருந்த பறவைகளின் இனிமையான சத்தம், காற்றுடன் கலந்திருந்தது. குயிலின் பாட்டு மிகவும் மயங்க

When I come home, I freshen up and eat the tastiest breakfast in my life. Later, my grandmother introduces a girl, Paavai. She goes to the village school. She lives down the street. She is very eager to show me around the village. Paavai shows me how to play with a tyre and a stick. We happily run down the lanes balancing the tyre with a small stick. We stop to talk to Paavai’s friends, Amir, Peter and Umaiyal.

நான் வீட்டுக்கு வந்து, புத்துணர்வு பெற்று, என் வாழ்விலேயே சுவையான காலை உணவை சாப்பிட்டேன். பின்னர், பாவை என்ற ஒரு சிறுமியை என் பாட்டி என்னிடம் அறிமுகப்படுத்தினார். அவர் அங்கு கிராம பள்ளயில் படிக்கிறாள். அதே தெருவில் அவள் வாழ்கிறாள். எனக்கு கிராமத்தை சுற்றிக் காட்ட அவள் வெகு ஆர்வமாக இருந்தாள். ஒரு டயரையும், ஒரு தடியையும் கொண்டு எப்படி விளையாடுவது என அவள் காண்பித்தாள். சிறு தடியால் டயரை லாவகமாக ஒட்டிக் கொண்டு | நாங்கள் மகிழ்ச்சியுடன் தெருக்களில் ஓடினோம். பாவையின் நண்பர்களான அமீர், பீட்டர் மற்றும். உமையாள் ஆகியோரிடம் நாங்கள் பேசினோம்.

All children here too have their summer vacation. Amir is helping his father in milking their cows. He let me pat his black calf peter and Umaiyal are sitting with their grandmother breaking groundnut pods and piling them neatly. Later they will take the nuts to the village market to sell them. I help them for some time.

இங்கு எல்லா குழந்தைகளும் கோடை விடுமுறையை கொண்டாடினர். பசுக்களிடமிருந்து பால் கறப்பதற்கு அமீர் தன் தந்தைக்கு உதவியாக இருந்தான். அவனது கறுப்பு நிற கன்று குட்டியை 5C4025 தா பாivale c++ine + +oin தட்டிக் கொடுக்க என்னை அனுமதித்தான். பீட்டரும் உமையாளும் அவர்களது பாட்டியுடன் அமர்ந்தபடி வேர்க்கடலையின் மேல் தோலை உடைத்து, அதனை குவியலாக சேர்த்து வைத்தனர். பிறகு அவர்கள் வேர்க்கடலையை கிராம – சந்தைக்கு எடுத்துச் சென்று விற்றுவிடுவர். நானும் அவர்களுக்கு சற்று நேரம் உதவி செய்தேன்.

13th April:13 ஏப்ரல் :
Paavai takes me to the village pond There are many children splashing around in the pond. Some boys are climbing to the top of the tall tamarind tree. Girls are playing hide and seek near the big banyan tree.

கிராமத்தின் குளத்திற்கு பாவை என்னை அழைத்துச் சென்றாள். அந்த குளத்தில் பல குழந்தைகள் நீரில் விளையாடிக் கொண்டிருந்தனர். சில சிறுவர்கள் அங்கிருந்த உயரமான புளிய மரத்தின் உச்சிக்குச் செல்ல, மரத்தில் ஏறிக் கொண்டிருந்தனர். அங்கிருந்த பெரிய ஆலமரத்தின் அருகில் சிறுமிகள் கண்ணாமூச்சி’ விளையாடிக் கொண்டிருந்தனர்.

My mother and my aunties take me to the river for a refreshing bath. I play for some time in the cool water but I cannot swim. So, I sit on a smooth rock and watch my friends swim like experts. They talk and laugh a lot as they wash their clothes and dry their hair in the Sun. The river is so clean that I can see the pebbles in the riverbed and colourful fish swim by. I love the scenery.

என் அம்மாவும், என் அத்தைகளும் என்னை ஆற்றுக்கு அழைத்துச்சென்றனர், புத்துணர்வூட்டும் bia குளியலுக்காக. அந்த குளிர்ந்த நீரில் நான் சற்று நேரம் விளையாடினேன். ஏனெனில் என்னால் நீந்த முடியாது. ஆகவே, நான் ஒரு பெரிய வழுவழுப்பான பாறையின் மீது அமர்ந்து, எனது நண்பர்கள் (திறமைசாலிகளைப் போல) நீந்துவதை பார்த்துக் கொண்டிருந்தேன். அவர்கள் அதிகமாக பேசியபடியும், சிரித்தபடியும் இருந்தனர். அவர்கள் தங்கள் துணிகளை துவைத்தனர். சூரிய ஒளியில் தலைமுடிளை உலர்த்திக் கொண்டனர். அந்த ஆறு மிகவும் சுத்தமாக இருந்ததால், அங்கு கூழாங்கற்களையும், வண்ணமயமான மீன்கள் நீந்திச் செல்வதையும் என்னால் பார்க்க முடிந்தது. அந்த இயற்கைக் காட்சியை நான் விரும்பினேன்.

We are back to our home in the city. The trip to our grandparents home was so enjoyable. Those two days flew by so fast. I realised that during this stay. I had neither watched television nor played video games. I eagerly looking forward to our next visit.

சென்று வந்த பயணம் மிகவும் மகிழ்ச்சியைத் நான் டெலிவிஷன் பார்க்காததையும், வீடியோ விளையாட்டு விளையாடாததையும் உணர்ந்தேன். எனது அடுத்த பயணத்திற்காக நான் ஆவலுடன் எதிர்பார்த்து காத்திருக்கிறேன்.
