Comparison of Adjectives

IX English I 19.04.2020

Practice worksheet-Grammar No:2

imagination Imagine you are a member of the fire brigade. Write a story about a forest fire you once had to tackle. Use the help words and ideas given in the box below.

On duty at the station,

Emergency call

Frantic citizen

Team mobilized

Outskirts of city

Terrified woodland animals

Powerful surge o0f water

Back up units arrived

Fire under control

Notes 1. When two things are compared, the comparative degree of the adjective should be used. Eg: She is fairer of the two sisters. (not the fairest) Who is more intelligent of the two brothers? (not the most intelligent) 2. When a comparison is made by means of a comparative followed by than the thing that is compared must always be excluded from the class of things which it is compared by using the word: other: Iron is more useful than any other metal. It means that iron is more useful than any other metal. Since iron itself is a metal. Other examples are given below:

Tagore is greater than any other author. Solomon was wiser than all other men. 3. When a comparison is made by means of a Superlative degree, the thing or class of things compared must be included in the comparison of the Superlative. Eg: Ganga is said to be the holiest of all the rivers. (Not all other rivers) He is the cleverest of all the pupils. (Not all other pupils) 4. When the second form of a comparison is given, it must correspond in construction with the first: Eg: The population of Uttar Pradesh is greater than that of any other state in India. (It is incorrect to state that the population of Uttar Pradesh is greater than any other state in India. Remember that what is compared is the population and not the states.) 5. Comparatives ending in or are followed by to instead of than. Eg: This necklace is superior to that one. His painting is inferior to yours. Q.2. Rewrite the following sentences according to the instructions given after each. Change only what you are asked and make a correct sentence. You have to make your sentence say the same thing in a different way.

1. Very few cities are as large as Kolkata

2.

3.

4.

5. No other substance is as hard as diamond. (Use: hardest)

8.

9. This town is not so clean as that town. (

10. She is as fresh as a flower. (Begin: A flower

(iii) Few, fewer, fewest are used to denote a large number of people or things.

Example: few people, fewer corrections, fewer arrivals.

(iv) Elder, eldest are used for persons of the same family.

There or Their?
