Esercizi B2 Word Formation con risposte (Gratis)

Risposta: volunteers

VOLUNTEER → volunteers.

A team consists of several people, so ‘a team of’ needs the plural noun volunteers here. Add -s to volunteer. Voluntary is an adjective and cannot name the people in this gap.

Risposta: explanation

EXPLAIN → explanation.

“Each visitor received a short explanation of the safety rules.” The article a and adjective short introduce a singular noun. Explain is a verb; its noun is explanation, with no i after the a. Simply adding -ation to explain gives the incorrect spelling explaination. Read the whole noun phrase: a short explanation, but an explanation if short is omitted.

Risposta: patiently

PATIENT → patiently.

The gap describes how visitors should wait, so it needs an adverb. Add -ly to the adjective patient. ‘Without complaining’ supports patiently, rather than the negative form impatiently.

Risposta: impossible

POSSIBLE → impossible.

The shops had said that nothing could be done, so the writer initially believed the radio could not be repaired. The adjective must therefore be negative: impossible. Possible takes the prefix im-, not un- or in-.

Risposta: solution

SOLVE → solution.

‘A simple’ needs a singular noun, and the usual phrase is ‘a solution to a problem’. The verb solve changes to the noun solution. Do not use solving after ‘a simple’ in this phrase.

Risposta: clearly

CLEAR → clearly.

We need to describe how the engineer explained the steps, so the adjective clear becomes the adverb clearly. The result, ‘everyone could follow her instructions’, confirms the positive meaning. Keep the r before -ly.

Risposta: reduction

REDUCE → reduction.

The article ‘a’ needs a singular noun. Repairing the objects created less waste, so we need reduction, in the phrase ‘a reduction in waste’. Notice the spelling change from reduce to reduction; it is not reducetion.

Risposta: understanding

UNDERSTAND → understanding.

In ‘a much better ... of’, the gap names the knowledge the writer gained. Add -ing to understand to make the noun understanding. Here it is a noun, not part of a continuous verb tense.
