Answer the following question.
How do desert animals survive without water?

उत्तर
Desert animals cannot survive without water. They find different ways of coping with the harsh desert conditions. For example, gerbils spend the hottest part of the day in cool burrows. And darkling beetles catch moisture on their legs and then lift them into the air till the drops trickle down into their mouths.

The teacher will read out the story of a young girl about a special day.
One day our teacher announced that there was a surprise awaiting us the next day. We were asked to get whatever little pocket money we could.
The next day our teacher said, 'Today is Grandparents' Day' and you will be meeting many grandparents who do not live with their families. Yes, we were going to an Old Age Home! On the way we bought a nice big cake, chart paper and balloons. We entered an old, big building. Later we were taken into a hall and were allowed to decorate it.
We blew balloons and hung them around the hall. We cut out chart paper, wrote quotes, drew pictures and stuck them on the wall. Then came in all the grey–haired sweethearts, some alone, some couples, some in groups ans settled down.
It was time to welcome them. Robert, who was a good speaker, greeted them and told them that we had come along to make their day a little special. We gathered in front and started singing songs for them. Most of the people were single grandparents whose spouses had expired. The other few were couples; many of them were smiling and singing along too. But there were a few who sat without any expression. While some of us sang the others sat beside them and spoke to them.
Two of us cut the cake into several pieces to be distributed. We were informed by the caretaker that there were diabetic people amongst them and they couldn't have sweets. He said they could have fruit instead the non-diabetics and fruit to those who were diabetic. Many of them missed their grand children. One of them told me that her son was in the U.S. and as he found it difficult to look after her, he had left her at this Home.
While returning home we realized that our grandparents are lonely and insecure. They spend their second childhood in their old age homes. Most of those living in old age homes do not complain. It is left to us to decide how happy their old age can be. We do not need any special day to make them feel their worth. If you have never told them how much you love them, say it before it's too late.
(b) List any three feelings of the old people in this story.

Read this article about the great Indian Rhinoceros. [You will find the information useful for your group discussion in 5.]
The Indian Rhinoceros or the Great One-Horned Rhinoceros or the Asian Onehorned Rhinoceros (Rhinoceros unicomis) is a large mammal primarily found in north-eastern India, Nepal and parts of Bhutan. It is confined to the tall grasslands and forests in the foothills of the Himalayas.
The Indian Rhinoceros once ranged throughout the entire stretch of the Indo Gangetic Plain but excessive hunting reduced their natural habitat drastically.
Today, about 3,000 Indian Rhinos live in the wild, 1,800 of which are found in Assam alone. In 2008, more than 400 Indian Rhinos were sighted in Nepal's Chitwan National Park.
In size it is equal to that of the White Rhino in Africa; together they are the largest of all rhino species. The Great One-Horned Rhinoceros has a single horn; this is present in both males and females, but not on newborn young. In most adults, the horn reachee a length of about 25 centimetres, but has been recorded up to 57 .2 centimetres in length. The nasal hom curves backwards from the nose. The horn is naturally black.
This prehistoric-looking rhinoceros bas thick, silver-brown skin which becomes pinkish near the large skin folds that cover its body. The male develops thick neckfolds. It has very little body hair aside from eyelashes, ear-fringes and tail-brush.
These rhinos live in tall grasslands and riverine forests, but due to the loss of habitat, they have been forced towards cultivated land. They are mostly solitary creatures, with the exception of mothers and calves and breeding pairs, although they sometimes, congregate at bathing areas.
The Indian Rhinoceros makes a wide variety of vocalizations. At least ten distinct vocalizations have been identified: snorting, honking, bleating, roaring, squeak panting, moo-grunting, shrieking, groaning, rumbling and humphing. In addition to noises, the rhino also uses olfactory communication.
In aggregation, Indian Rhinos are often friendly. They will often greet each other by waving or bobbing their heads, mounting flanks, nuzzling noses, or licking. Rhinos will playfully spar, run around, and play with twigs in their mouth. Adult males are the primary instigators of fights. Fights between dominant males are the most common cause of rhino mortality. Indian rhinos have few natural enemies, except for tigers. Tigers sometimes kill unguarded calves, but adult rhinos are less vulnerable due to their size. Humans are the only other animal threat, hunting the rhinoceros primarily for sport or for the use of its horn. Indian Rhinos have been somewhat tamed and trained in circuses, but they remain dangerous and unpredictable animals.
In the nineteenth and early twentieth century, the Indian Rhinoceros was hunted relentlessly. Reports from the middle of the nineteenth century claim that some military officers in Assam individually shot more than 200 rhinos. In the early 1900s, officials became concerned at the rhinos' plummeting numbers. By 1908 in Kaziranga, one of the Rhinos' main ranges, the population had fallen to around 12 individuals. In 1910, all rhino hunting in India became prohibited.
The rhino has been a major success in conservation. Only 100 remained in the early 1900s; a century later, their population has increased to about 2500 again, but even so, the species is still endangered. The Indian rhino is illegally poached for its horn. Some cultures in East Asia believe that the hair has healing and potency powers and therefore is used for traditional Chinese medicine and other Oriental medicines.
The Indian and Nepalese Governments have taken major steps towards Indian Rhinoceros conservation with the help of the World Wildlife Fund (WWF). The Kaziranga National Park and Manas National Park in Assam, Pobitora Reserve Forest in Assam {having the highest Indian rhino density in the world), Orang National Park of Assam, Laokhowa Reserve Forest of Assam (having a very small population) and Royal Chitwan National Park in Nepal are homes to this endangered animal.
The Mystery of Bermuda Triangle.
The potential of nature, of discovered and undiscovered elements in our world, persuades us to probe into some of her mysteries and what they may tell us. Prepare yourself then for a true odyssey of the Earth around us.

Air France Plane Misalng Near Bermuda Triangle The date was January 8, 1962. A huge 4 engine KB50 aerial tanker was enroute from the east coast to Lajes in the Azores. The captain, Major Bob Tawney, reported in at the expected time. All was normal, routine. But he, his crew and the big tanker, never made it to the Azores. Apparently, the last word from the flight had been the usual routine report, which had placed them a few hundred miles off the East Coast. |

Bermuda Triangle Theories
The Bermuda triangle is a stretch over the Atlantic Ocean, measuring less than a thousand miles on any one side. The name 'Bermuda Triangle' remained a colloquial expression throughout the 1950s. By the early 1960s, it acquired the name 'The Devil's Triangle.' Bordered by Florida, Bermuda, and Puerto Rico, the location became famous on account of the strange disappearance of ships, as well as aircrafts in the area. A number of supernatural explanations have been put forward with regard to the mysterious disappearances.
However, many probable logical explanations for the missing vessels include hurricanes, earthquakes, as well as magnetic fields, which render navigation devices worthless. However, most people do not like to accept such boring explanations and instead opt for more interesting options like alien abduction, giant squids, or getting sucked into another dimension.
Supernatural theories
| Death Rays from Atlantis. Rays from the magic crystals, left from the time of Atlantis, deep down in the sea are responsible for the strange sinking of ships. However, several underwater expeditions have revealed places under the ocean that look man-made, but no such crystals have been found. In fact no real proof that Atlantis existed, has been ever found. |
| Sea monsters. The presence of sea monsters was the most widely believed explanation especially in the earlier times, when their existence was believed to be true. |
|
Presence of a time warp. People claim to be lost in the time warp while going through the region. |
| Alien abductions. The Bermuda Triangle is a collecting station from where aliens take our people, ships, planes and other objects back to their planet to study. |
Scientific Explanations
Magnetic Compass
According to the scientists in the US Navy, this area is one of the only two in the world, where a magnetic compass points to true north rather than magnetic north. This probably caused some navigators to go off course, which is very dangerous because many of the islands in 'The Triangle' have large areas of shallow water where vessels can run aground. They can also sink a long way down as some of the ocean's deepest trenches, from 19 ,000 to over 27 ,000 feet below sea level, are found here.
Unpredictable weather
Since the island is situated in the Atlantic Ocean, the weather is influenced by several factors and can change instantly. That means that at one moment the weather is stable, and at another it becomes extremely turbulent accompanied by strong currents of wind along with the hurricanes.
Formation of methane in the sea.
Methane can lower the density of water, leading to the sinking of ships. Similarly, methane can cut out an aircraft engine leading to crashes.
Bermuda Triangle Survivors
These witnesses constitute a long list of pilots, sailors and fishermen.
1. It is interesting to note that Christopher Columbus was one such witness. He wrote in his memoir on how his compass acted strangely while sailing through the Bermuda Triangle. He along with another shipmate witnessed a glowing globe of light that seemed to hover over the sea.
2. It is said that when clouds or fog enter the Bermuda Triangle, strange things start happening. Such a phenomenon has been witnessed with the Philadelphia Experiment in which the USS Eldridge vanished and reappeared later miles away, with some of the crew men warped into the hull of the ship.
3. In 1901, Anne Moberly and Eleanor Jourdain stepped into a mist and claimed to arrive at a time period before the French Revolution. It is said, that the mist and the ominous clouds might be the key to time travel or entering into other dimensions.
4. Even a great pilot like Charles Lindbergh witnessed unusual events while flying in the reaches of the Bermuda Triangle. It is said that when he was making a nonstop flight from Havana to St. Louis, his magnetic compass started rotating. His Earthinductor-compass needle jumped back and forth erratically. This has now all been revealed in his autobiography.
5. Another eyewitness account is that of Bruce Gernon, who flew his plane, a BonanzaA36, into the Bermuda Triangle and encountered a non-threatening mile and a half long cloud. As he neared, the cloud seemed to come alive. It became huge and engulfed his plane. However, a tunnel opened up in the cloud and he went through this tunnel. It had cloud trails swirling around his plane. He also reported that while going into this tunnel, he experienced zero gravity and the only thing that kept him in the cockpit was his seatbelt.
Whatever be the actual reason, there is an involvement of more than one fact.or behind the disappearances of ships and aircrafts in the Bermuda triangle region.
The Bermuda triangle continues to evoke a lot of interest. Most people like to read about it. In fact., in the last few decades, island of Bermuda has emerged as a major tourist destination as well; mainly, due to its close proximity with the Bermuda Triangle.
Mrs. Thompson did not reply, but presently turned towards the little chamber where her husband had deposited Maggie; and, pushing open the door, went quietly in. Joe did not follow; he saw that, her state had changed, and felt that it would be best to leave her alone with the child. So he went to his shop, which stood near the house, and worked until dusky evening released him from labor. A light shining through the little chamber windows was the first object that attracted Joe’s attention on turning towards the house: it was a good omen. The path led him by this windows and, when opposite, he could not help pausing to look in. It was now dark enough outside to screen him from observation. Maggie lay, a little raised on the pillow with the lamp shining full upon her face. Mrs. Thompson was sitting by the bed, talking to the child; but her back was towards the window, so that her countenance was not seen. From Maggie’s face, therefore, Joe must read the character of their intercourse. He saw that her eyes were intently fixed upon his wife; that now and then a few words came, as if in answers from her lips; that her expression was sad and tender; but he saw nothing of bitterness or pain. A deep-drawn breath was followed by one of relief, as a weight lifted itself from his heart.
Read the extract given below and answer the question that follow.
Why did Joe not follow Mr s Thompson? What had changed her?
After washing from his hands and face the dust and soil of work, Joe left the kitchen, and went to the little bedroom. A pair of large bright eyes looked up at him from the snowy bed; looked at him tenderly, gratefully, pleadingly. How his heart swelled in his bosom! With what a quicker motion came the heart-beats! Joe sat down, and now, for the first time, examining the thin free carefully under the lamp light, saw that it was an attractive face, and full of a childish sweetness which suffering had not been able to obliterate.
“Your name is Maggie?” he said, as he sat down and took her soft little hand in his.
“Yes, sir.” Her voice struck a chord that quivered in a low strain of music.
“Have you been sick long?”
“Yes, sir.” What a sweet patience was in her tone!
“Has the doctor been to see you?”
“He used to come”
“But not lately?”
“No, sir.”
Read the extract given below and answer the questions that follow.
What did Joe notice about Maggie in the light of the lamp?
Joe did not see the Guardians of the Poor on that day, on the next, nor on the day following. In fact, he never saw them at all on Maggie’s account, for in less than a week Mrs. Joe Thompson would as soon leave thought of taking up her own abode in the almshouse as sending Maggie there.
What light and blessing did that sick and helpless child bring to the home of Joe Thompson, the poor wheelwright! It had been dark, and cold, and miserable there for a long time just because his wife had nothing to love and care for out of herself, and so became soar, irritable, ill-tempered, and self-afflicting in the desolation of her woman’s nature. Now the sweetness of that sick child, looking ever to her in love, patience, and gratitude, was as honey to her soul, and she carried her in her heart as well as in her arms, a precious burden. As for Joe Thompson, there was not a man in all the neighbourhood who drank daily of a more precious wine of life than he. An angel had come into his house, disguised as a sick, helpless, and miserable child, and filled all its dreary chambers with the sunshine of love.
