Final answer:
To correctly complete the sentences, 'cheaply' and 'well' should be used as the adverbs to modify the verbs 'went' and 'did.'
Step-by-step explanation:
The student is asking about how to use adverbs in sentences. An adverb modifies a verb, an adjective, or another adverb, often ending in -ly. For the sentences provided, the correct adverbs would be “cheaply” and “well,” since “cheap” is an adjective and must be changed to an adverb to modify the verb “went”, and “good” is an adjective that becomes the adverb “well” to modify the verb “did.”
Here is how the completed sentences should read:
- We went on holiday cheaply.
- We did the test well.
Remember, when transforming adjectives like “cheap” and “good” into adverbs, we often use the -ly suffix or use a different word form that acts as an adverb.
