The Desert NCERT Text Book Questions and Answers

The Desert Comprehension check-I

Question 1.
From the first paragraph

i. pick out two phrases which describe the desert as most people believe it is.
Answer:
an endless stretch of sand where no rain falls/dry, hot, waterless and without shelter; a flat, unchanging wasteland of dry sand

ii. pick out two phrases which describe the desert as specialists see it. a beautiful place; home of a variety of people, animals and plants
Answer:
I think the description of a desert as a beautiful place where different kinds of flora and fauna can survive is a more apt description. This is so because there is a popular misconception that a desert is dry, hot, waterless and without shelter, but this is not true. Deserts have flowers and also get rain (though not as often). Deserts may also have oasis, a green island in the middle of a desert.In fact, deserts are not always hot. For example, while Thar is a hot desert, Ladakh is a cold one.

Question 2.
The phrases on the left in the following box occur in the text. Match each of them with a phrase on the right. Solved
Answer:

• an endless stretch of sand—nothing but sand as far as one can see
• waterless and without shelter—no water and no shade
•  an oasis—fertile place with water and plants in a desert
• hidden by a cover of grass—not visible because the grass is thick

The Desert Comprehension check-II

Question 1.
A camel can do without water for days together. What is the reason given in the text?
Answer:
A camel can do without water for days together. The reason is they sweat very little. They can stand high body temperature. They don’t need to sweat and can, therefore, retain the water they drink for long periods of time.

Question 2.
How do the smaller desert animals fulfil their need for water?
Answer:
The smaller desert animals do not drink water. They burrow underground during the hot day and come out at night to eat. Some of them eat other animals and get the water they need from the moisture in the meat. Others eat plants and seeds and get the water they need from plant juices.

Question 3.
In a desert the temperature rises during the day and falls rapidly at night. Why?
Answer:
In hot and humid climates, the moisture in the air acts like a blanket and protects the Earth’s surface from the hot rays of the sun. The absence of this blanket in desert lands causes the desert to heat up rapidly during the day and to cool off rapidly at night.

The Desert Exercises Question and Answer

Do the following activities in groups.

Question 1.
Describe a desert in your own way. Write a paragraph and read it aloud to your classmates.
(Encourage the students to complete the given activities in groups.)
Answer:
A desert is a strange and surreal place that has so much to offer to us. To me, deserts seem to have a personality of their own—a tough place that has survived so much hostility from Mother Nature. It is a place with colourful people who have so many forgotten tales to tell us. I believe it’s a magical place in its own way.

It is an expanse of land that has taught us one thing, and that is, that human beings can survive in any place of the planet. The unfathomable quiet of the desert makes one delve deeper into one’s soul and find answers to questions forgotten and buried. Everybody should visit deserts at least once.

Question 2.
Go to the library and collect information about the lifestyle of people in desert areas—their food, clothes, work, social customs, etc. Share this information with the group.
Answer:
The Thar Desert is home to approximately 40% of the total population of Rajasthan. The main occupation of the people who live here is agriculture and animal husbandry. The culture followed by the people of this desert can be best described as colourful and rich. There are many here who appreciate folk music and folk poetry.

A majority of the people who live here live a nomadic life. They rear cattle like goats, cows and camels. They look for food and water by moving from one place to another. Some of them are craftsmen and earn their living by selling their goods.

Some common crops grown by the people of Rajasthan include bajra, jowar, wheat and mustard seeds. Other means of livelihood are the industries such as textiles, sugar, cement and fertilizers, and mines of iron-ore, zinc and lead. Rajasthan is well-known for its magnificent handicrafts and jewellery.

One can see the women of Rajasthan donning colourful ghaghra-cholis with an odhni or chunni. The men can be seen wearing dhoti-kurta with turbans so as to protect themselves from the harsh rays of the sun.

Trees NCERT Solutions for Class 7 English Honeycomb Poem 5

Trees NCERT Text Book Questions and Answers

Trees Working with the poem

Question 1.
What are the games or human activities which use trees, or in which trees also ‘participate ’?
Answer:
Some of the games or human activities which use trees include making tree houses, or swings; having tea parties under them; hiding behind them in hide-and-seek; and using them for shade in the summers.

Question 2.
i. “Trees are to make no shade in winter. ” What does this mean?
(Contrast this line with the line immediately before it.)
Answer:
This means that in autumn and winter, trees shed their leaves and do not provide shade anymore. In contrast, during the summers, trees provide us shade and keep us cool.

ii. “Trees are for apples to grow on, or pears. ’’ Do you agree that one purpose of a tree is to have fruit on it? Or do you think this line is humorous?
Answer:
I think the line is merely humorous because the poet has already enumerated the several benefits of the trees. In fact, the purpose of the trees is much beyond providing us with fruits.

Question 3.
With the help of your partner, try to rewrite some lines in the poem, or add new ones of your own as in the following examples.
(Encourage the students to use their creativity to formulate the answers.) Sample answer:
Answer:
Trees are for birds to build nests in.
Trees are for people to sit under.
Trees are used to make medicine.
Trees save us from rain, lighening and thunder.

Trees give us all the food.
Trees are there to give us wood.

Now try to compose a similar poem about water, or air.

Poem on Water

The Earth is ninety percent water,
And its protection is an important matter.
Water gives us life.
It is the reason we have marine life.
Water makes the fish swim,
And. helps one to stay slim.
Water is why we all exist.
And we must save it, I insist.

Chivvy NCERT Solutions for Class 7 English Honeycomb Poem 4

Chivvy NCERT Text Book Questions and Answers

Chivvy Working with the poem

Discuss these questions in small groups before you answer them.

Question 1.
i. When is a grown-up likely to say this?
Don’t talk with your mouth full.
Answer:
When we are eating food

ii. When are you likely to be told this?
Say thank you.
Answer:
When someone gives us a present, or pays us a compliment

iii. When do you think an adult would say this?
No one thinks you are funny.
Answer:
When a child pulls a prank, or some mischief

Question 2.
The last two lines of the poem are not prohibitions or instructions. What is the adult now asking the child to do? Do you think the poet is suggesting that this is unreasonable? Why?
Answer:
In the last two lines, the adult is asking the child to make up his own mind about things. Yes, the poet is suggesting this is somewhat unreasonable because first the adult asks the child to do everything according to his wishes, and suddenly they blame the child that he does not do anything on his own.

Question 3.
Why do you think grown-ups say the kind of things mentioned in the poem? Is it important that they teach children good manners, and how to behave in public?
Answer:
Grown-ups have the best interests of children in mind when they ask them not to do something. They have more experience of the world, and know how the world works. Yes, it is important that they teach children good manners, and how to behave in public because the lack of good manners creates problems for others. For example, if a child yells at a public place like in the metro, they are creating a nuisance for everybody else. And this is not fair to other people who would like to, let’s say, read or meditate, or just catch a shuteye.

Question 4.
If you had to make some rules for grown-ups to follow, what would you say? Make at least five such rules. Arrange the lines as in a poem. (Encourage the students to use their creativity and come up with their own answers.)
Answer:
Please don’t tell me what to do all the time.
Don’t make me eat avacodo, gourds or lime.
Don’t give me milk.
Or make me wear silk.
Please don’t make me recite poems in front of everybody Or not let me play outside because it’s so muddy.
