Sure! Let's break down the exercises step by step.
Exercise 1
In this exercise, we need to add the correct prefixes to create opposites of the adjectives provided. The prefixes we can use are: il-, im-, in-, ir-, and un-.
Here's a quick summary of the prefixes:
- il-: used before words starting with 'l' (e.g., legal → illegal)
- im-: used before words starting with 'm', 'p', and 'b' (e.g., possible → impossible)
- in-: used before words starting with 'c', 'd', 'g', 'l', 'r', 't' (e.g., adequate → inadequate)
- ir-: used before words starting with 'r' (e.g., regular → irregular)
- un-: used widely for many adjectives (e.g., active → inactive)
Let's fill in the table based on these rules:
| Adjective | Prefix | Opposite |
|---|---|---|
| active | un- | inactive |
| adequate | in- | inadequate |
| coherent | incoherent | |
| compatible | incompatible | |
| complete | incomplete | |
| conscious | unconscious | |
| controllable | uncontrollable | |
| dependent | independent | |
| digested | indigestible | |
| direct | indirect | |
| fertile | infertile | |
| fit | unfit | |
| healthy | unhealthy | |
| hygienic | unhygienic | |
| legal | illegal | |
| movable | immovable | |
| operable | inoperable | |
| palpable | impalpable | |
| pure | impure | |
| qualified | unqualified | |
| reducible | irreducible | |
| regular | irregular | |
| sanitary | unsanitary | |
| soluble | insoluble | |
| stable | unstable | |
| well | unwell |
Exercise 2
Now, we will use fifteen of the adjectives from the table to complete the sentences. The first one has been done for you:
- He was found unconscious in the street.
- He felt unwell and had to go home.
- The serum makes the poison inactive.
- The children have a very unhealthy diet.
- The nurse noted that the patient had developed an irregular pulse.
- She used to play a lot of tennis, but she became inactive in the winter.
- The surgeon decided that the cancer was inoperable.
- Cholera spread rapidly because of the unsanitary conditions in the town.
- The patient was showing signs of an inadequate mental condition.
- She has an irrational desire to drink alcohol.
Extension
As suggested, you can practice with a partner by asking questions about the opposites of the adjectives you discussed. For example:
- “What’s the opposite of conscious?”
- The answer is: unconscious.
This practice will help reinforce your understanding of the prefixes and their usage in English! If you have any further questions or need clarification, feel free to ask!
