English WORKSHEET 1 [ Week 4 ]

ON KILLING A TREE

Read the extracts given below and answer the questions that follow.

Question 1.

It takes much time to kill a tree,

Not a simple jab of the knife

Will do it. It has grown

Slowly consuming the earth,

Rising out of it, feeding

Upon its crust, absorbing

Years of sunlight, air, water,

And out of its leprous hide

Sprouting leaves.

(a) Why does it take so much time to kill a tree?

(b) What does it consume?

(c) What does a tree absorb?

(d) Explain “leprous hide”.

Question 2.

So hack and chop

But this alone won’t do it.

Not so much pain will do it.

The bleeding bark will heal

And from close to the ground

Will rise curled green twigs,

Miniature boughs

Which if unchecked will expand again

To former size.

(a) Why does the poet say ‘killing’ a tree rather than cutting it?

(b) “But this alone won’t do it..- What does ‘this’ refer to here? What does ‘it’ refer to?

(c) What does the phrase ‘bleeding bark’ mean?

(d) What are processes suggested to do it?

WORKSHEET 2 [ Week 4 ]

Question 3.

So hack and chop

But this alone won’t do it.

Not so much pain will do it.

The bleeding bark will heal

And from close to the ground

Will rise curled green twigs,

Miniature boughs

Which if unchecked will expand again

To former size.

(a) Explain “hack and chop”?

(b) What do you mean by ‘not so much pain will do it’?

(c) Where will the curling green twigs rise from?

(d) What finally kills the tree?

Question 4.

Then the matter

Of scorching and choking

In sun and air,

Browning, hardening,

Twisting, withering,

And then it is done.

(a) “Then the matter..” What does ‘Then’ refer to?

(b) What role do the sun and air play in killing a tree?

(c) “The strength of the tree exposed.” Explain.

(d) What will happen if the miniature boughs are left unchecked?
