Actually, go and try to figure it out yourself.
Correct Answers
It's no use... + present participle is a set expression. The participle must use -ing, so only no use trying is acceptable here.
Again we need to use the -ing form of the verb, but we can't use the word to with a present participle.
Note that here we need a predicative adjective, which is formed using the present participle: exciting.
Here the past tense looked indicates we need to use the participle form having as the auxiliary verb.
There's no point in... is another set expression that requires the present participle -ing form: no point in guessing.
We need to follow the preposition about with a noun (Argentina) and a gerund (-ing). The correct phrasal verb form is: making it.
We need to change the word lose to its present participle form in order to create an adjective describing the team.
In this sentence our team functions as a possessive noun and so it requires the gerund arriving.
The set expression not worth... also requires the present participle -ing form: not worth buying.
Although the verb be is used to form the present continuous for is not thinking, after the preposition about we have to use a gerund: winning.
We have to follow the preposition of with the gerund (-ing), but we can't use it twice as in having winning. This event is the past so having won is the correct answer.
Here we need a gerund (-ing) to follow the possesive noun: Russia's.
This is an action currently taking place, so we need to use the present continuous. Germany and England must be followed by the third-person plural.
We need a noun after the phrasal verb be confident about and the gerund form making serves this purpose.
Again the preposition must be followed by a simple gerund (-ing), as the first part of the sentence refers to the present.
The set expression have so much trouble... also requires the present participle -ing form: trouble finding.
This is a future tense sentence and doesn't require the gerund or a participle. We don't need to change the form of the main phrasal verb head to, as it follows the auxiliary will.
This sentence is more complex, but we can think of their hotel and training ground as a possessive noun here. This means it must be followed by the gerund (-ing).
Here we have a preposition (with) and so the correct form here must be a gerund. However, we still need to use the subject: Russia for the sentence to make sense.
Gerund
A gerund is the -ing form of a verb used as a noun — swimming, reading, being late. It can sit in any position a noun can: as the subject (Swimming is fun), as the object of a verb (I enjoy swimming), or as the complement of a preposition (She's good at swimming).
Gerunds matter because dozens of common English verbs and almost every preposition force you into the -ing form. Pick the wrong shape — I enjoy to swim, good at to swim — and the sentence sounds clearly off to a native speaker. Knowing which contexts demand a gerund (vs. an infinitive) is what makes verb patterns click.
Participle
A participle is a verb form that doubles as an adjective or adverb. English has two: the present participle ending in -ing (running, sitting) and the past participle (broken, gone, written). Both build tenses (is running, has gone), but they also stand alone modifying nouns (the broken window) or verbs (Exhausted, we fell asleep).
Participles look like simple parts of speech but pull double duty — most learner errors come from confusing the present participle with the gerund (also -ing but acting as a noun) or the past participle with the past tense.
B2 | Upper Intermediate
B2 is the upper-intermediate level in the CEFR framework, sitting between B1 and C1. At B2 you can read editorials, follow most TED talks without subtitles, and hold extended conversations on abstract topics — including topics outside your everyday life.
Grammatically, B2 means flexible control of mixed conditionals, passive voice across tenses, reported speech with proper backshifting, and participle clauses. B2 is the standard target for university entrance exams (IELTS 5.5–6.5, TOEFL 87–109) and most skilled-migration thresholds — knowing whether you're there shapes your study plan.
Difficulty: Hard
The Hard difficulty tag marks questions and challenges aimed at upper-intermediate to advanced learners — typically B2 and above. Expect interacting rules, edge cases, distractors that look right at first glance, and contexts where the surface meaning and the grammatical answer don't match.
Filter by Hard when you're past the basics and want material that genuinely tests your understanding. These questions catch the gaps your textbook didn't — register-sensitive choices, exception cases, mixed conditionals, the difference between would have been and had been.
