PROJECT INTEGRATION WITH ENGLISH
Task-1 Comprehension
(4marks-understanding and application of knowledge)
Read the following passage.
Rangan was a farmer in a small village. He was a hard working person. He lived
near his farm. His land has a deep well. Apart from the ground water, he thought
that the rain water can be collected in the well. After spending a little money for
buying pipes, Rangan set up the pipes in the roof and made rain water falling on the
roof to run through the tube and then into the well. Rainy season started and rain
water reached well. He advised the people in the town to set up rain water pipes on
the roof so that they can also save rain water. They did not listen to his words. They
made fun of him and they ignored his advice. They considered it a waste of money
to set up rain water harvesting pipes.
Summer season started. All of the water resources became drained. Lakes and
ponds became empty. This water scarcity troubled all the villagers. The villagers
decided to seek the village chief’s help. The chief asked them "Did your village get
rain during rainy season?" People replied that they got good rainfall in the rainy
season. Then the chief asked, “Why this drought if there was good rainfall?" The
villagers told that the lakes and ponds became empty. The chief again asked,
"Whether you are storing rain water in the well? The villagers said "No! We did not
save rainwater." He told them "Water is our life saver. It is an invaluable resource.
If you all would have saved the rain water, this scarcity would not have occurred
today’.
The villagers felt sorry for not realizing the need to save water. The chief informed
that, Rangan, a farmer in your village has stored rain water in the well in his farm.
CLASS – IV / SUMMER HOLIDAY HOMEWORK / pg. 18
He has accepted to offer water to your entire village this summer. He advised the
villagers to save rain water and reduce water wastage. People realized that they
need to save water and thanked the chief and Rangan. They all returned to the
village and rain water harvesting pipes were setup in every house. They all began
to save water and lived happily.
“Little drops of water make the mighty ocean. Rain water harvesting is one of
the best methods to save water.”

Pilgrims at the Triveni Sangam, the confluence of the Ganges, Yamuna and third mythical
river, the Saraswati River, in Allahabad (Prayagraj).
One such Triveni Sangam, in Prayagraj (Allahabad), has the confluence of three rivers —
the Ganges , the Yamuna and a third mythical river the Saraswati. The two rivers maintain
their visible identity and can be identified by their different colours. The water of the
Ganges is clear, while that of the Yamuna is greenish in colour.
