Q1  15
Q1 15

Question 1: She decided ___ a new language before her trip abroad.

Question 1 options
'To learn' is correct because an infinitive phrase is formed with 'to' + base verb. 'Learning' is a gerund, 'learned' is past tense, and 'learns' is a conjugated verb — none of these form an infinitive phrase.
Q2 15

Question 2: My goal this year is ___ at least three new skills.

Question 2 options
'To develop' is correct because an infinitive phrase ('to' + base verb) follows a linking verb like 'is' to function as a predicate nominative (noun). The other options are not base verb forms that work with 'to' in this structure.
Q3 15

Question 3: An infinitive phrase always begins with the word 'to' followed by a base form verb.

Question 3 options
True because an infinitive is always formed with 'to' + the base (uninflected) form of a verb, such as 'to run' or 'to speak'. A conjugated or inflected verb form after 'to' would be grammatically incorrect.
Q4 15

Question 4: In the sentence 'He trained hard to win the championship,' what role does the infinitive phrase 'to win the championship' play?

Question 4 options
'To win the championship' acts as an adverb because it answers the question 'Why did he train hard?' Infinitive phrases functioning as adverbs typically explain a reason or purpose for the action in the main clause.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • some books
  • She went
  • to the library
  • to borrow

Drag items or use arrows to arrange them in the correct order.

The correct order is 'She went to the library to borrow some books' because the infinitive phrase 'to borrow some books' follows the main clause and acts as an adverb explaining the reason for going to the library.
Q6 15

Question 6: Which sentence uses an infinitive phrase correctly?

Question 6 options
'She needs to submit the report by Friday' is correct because 'to submit' is properly formed as 'to' + base verb. 'To submitting' incorrectly adds -ing, 'to submitted' uses the past form, and 'to submits' uses a conjugated form — all are incorrect infinitive constructions.
Q7 15

Question 7: Customer: 'Why did you call the technician?' Shop owner: 'I called him ___ the broken machine in the back room.'

Question 7 options
'To fix' is correct because the infinitive phrase 'to fix the broken machine' acts as an adverb answering 'why' the shop owner called the technician. This expresses purpose, which is a key use of infinitive phrases as adverbs.
Q8 15

Question 8: Which sentence correctly uses an infinitive phrase rather than a prepositional phrase?

Question 8 options
'She went to buy groceries after work' uses an infinitive phrase ('to buy groceries') with 'to' + base verb. The other options use 'to' followed by a noun or pronoun, which forms a prepositional phrase, not an infinitive phrase.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • To speak fluently
  • requires
  • a lot of practice
  • in public

Drag items or use arrows to arrange them in the correct order.

The correct order is 'To speak fluently in public requires a lot of practice' because the infinitive phrase 'To speak fluently in public' functions as the subject of the sentence, followed by the verb 'requires' and its object.
Q10 15

Question 10: We are looking for a volunteer ___ the new students around the campus.

Question 10 options
'To guide' is correct because the infinitive phrase 'to guide the new students around the campus' functions as an adjective modifying the noun 'volunteer', describing what kind of volunteer is needed. The other options do not form a correct infinitive phrase.
Q11 15

Question 11: Which statement about infinitive phrases is true?

Question 11 options
An infinitive phrase can include an object and/or modifiers in addition to the infinitive itself — for example, 'to read the book carefully' contains the infinitive 'to read', an object 'the book', and a modifier 'carefully'. An infinitive phrase is not limited to just two words.
Q12 15

Question 12: Rewrite as an infinitive phrase that functions as a noun (subject): 'Swimming every day is his routine.' → ___ every day is his routine.

Question 12 options
'To swim' is correct because it transforms the gerund subject 'Swimming' into an infinitive, creating the infinitive phrase 'To swim every day' as the subject of the sentence. The other options are not correctly formed infinitives.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
To travel the world is her biggest dream.
He bought a notebook to record his ideas.
She is the best person to lead the project.
They want to finish the assignment before noon.
Infinitive phrase as an adverb (purpose)
Infinitive phrase as an adjective (modifying noun)
Infinitive phrase as a noun (direct object)
Infinitive phrase as a noun (subject)

Select an item on the left, then tap its match on the right.

Infinitive phrases can function as nouns (subject or object), adjectives (modifying nouns), or adverbs (explaining reason/purpose for an action).
Q14 15

Question 14: The word 'to' in an infinitive phrase is always the same as the word 'to' used in a prepositional phrase.

Question 14 options
False because in an infinitive phrase, 'to' is followed by a base form verb (e.g. 'to run'), while in a prepositional phrase, 'to' is followed by a noun or pronoun (e.g. 'to the store'). These are two different grammatical uses of the word 'to'.
Q15 15

Question 15: Which sentence uses an infinitive phrase to express a specific purpose rather than simply naming an action?

Question 15 options
'She woke up early to catch the first train' uses the infinitive phrase 'to catch the first train' as an adverb expressing purpose — it answers 'why she woke up early'. The other option uses the infinitive phrase as the subject, which names an action rather than explaining a reason.
