- Correct option: a) have finished
Explanation In time clauses referring to the future (starting with "when," "after," "as soon as"), the Present Perfect is used to emphasize that the action must be completed before the next one starts. Why other options are incorrect
- b) will finish: Future tenses are not used in subordinate clauses of time.
- c) am going to finish: Similar to "will," this construction is grammatically incorrect in a "when" time clause.
- Correct option: c) will wait (Note: The first blank is missing an option, but the response focuses on the provided list)
Explanation "Will wait" is a spontaneous decision or a promise made at the moment of speaking in response to the first person's statement. Why other options are incorrect
- a) will be waiting: This would imply a continuous action in progress at a specific moment, which is less common for a simple promise of arrival/waiting in this dialogue context.
- b) will have waited: This Future Perfect form implies the action will be finished by a certain time, which does not fit the context of a meeting.
- Correct option: c) sent
Explanation The phrase "the day before yesterday" is a specific past time marker, which requires the Past Simple tense. Why other options are incorrect
- a) sended: "Send" is an irregular verb; the past form is "sent."
- b) have sent: Present Perfect cannot be used with specific finished time expressions like "the day before yesterday."
- Correct option: c) must
Explanation "Must" is used here to express a strong logical deduction or certainty based on the evidence that no one is answering the phone. Why other options are incorrect
- a) can: Usually expresses ability or possibility, but "must" is the standard choice for logical certainty.
- b) have to: Expresses external obligation rather than a logical conclusion.
- Correct option: a) am playing
Explanation The Present Continuous is used for fixed arrangements and definite plans in the near future (playing with a friend tomorrow). Why other options are incorrect
- b) play: Present Simple is used for schedules (like trains or movies), not personal social plans.
- c) will play: Usually used for spontaneous decisions rather than pre-arranged activities.
- Correct option: b) will visit
Explanation "Will" is used for spontaneous decisions made at the moment of speaking. The speaker just learned about Tim's leg and decided to visit him right then. Why other options are incorrect
- a) am going to visit: Implies a prior intention or plan formed before the conversation.
- c) am visiting: Implies a fixed arrangement already made.
- Correct option: a) begins
Explanation The Present Simple is used for events that are part of a fixed timetable or schedule, such as a theater play. Why other options are incorrect
- b) begin: Incorrect subject-verb agreement (the play is singular).
- c) is beginning: Present Continuous is for personal arrangements, not formal schedules.
- Correct options: b) was shaving / a) cut
Explanation Past Continuous ("was shaving") is used for a long background action, and Past Simple ("cut") is used for a shorter, interrupting action. Why other options are incorrect
- a) shaved (first blank): Implies the action was a completed fact rather than a process being interrupted.
- b) was cutting (second blank): Cutting oneself is a momentary action, not a continuous process.
- Correct option: c) had met
Explanation The Past Perfect is used for an action that happened before another action in the past (meeting him happened before knowing/recognizing him). Why other options are incorrect
- a) met: Past Simple does not clearly show the sequence of two past events.
- b) was meeting: Past Continuous implies the meeting was in progress at that time, which doesn't fit the context.
- Correct option: a) can
Explanation "Can" expresses ability. Large print gives children the ability to read the books more easily. Why other options are incorrect
- b) have to: Implies an external obligation or necessity.
- c) must: Implies a strong internal necessity or logical deduction.
- Correct option: a) will be wearing
Explanation The Future Continuous is used to describe a state or action that will be in progress at a certain time in the future (at the moment they meet). Why other options are incorrect
- b) will wear: Suggests a decision to put the clothes on rather than the state of wearing them.
- c) will have worn: Future Perfect implies the action of wearing will be completed before they meet.
- Correct option: c) used to be
Explanation "Used to" describes a past state or habit that is no longer true (the dancehall was there but was knocked down). Why other options are incorrect
- a) was being: Incorrect usage for a permanent state in the past.
- b) had been: Past Perfect requires another past action to relate to, and usually describes a state completed before that action.
- Correct option: c) will have gone
Explanation The Future Perfect is used for an action that will be completed by a specific point in the future ("by the time I come"). Why other options are incorrect
- a) will go: Describes a future fact or decision, not completion by a deadline.
- b) will be going: Describes an action that will be in progress at that time.
- Correct option: c) arrive
Explanation In subordinate clauses of time (starting with "when"), the Present Simple is used instead of the future tense. Why other options are incorrect
- a) am going to arrive: Future constructions are not used in "when" clauses.
- b) will arrive: Grammatically incorrect in a time clause.
- Correct option: b) is raining
Explanation The Present Continuous is used for an action happening right now (at the moment of speaking), which is why the person needs an umbrella. Why other options are incorrect
- a) rains: Present Simple describes habits or general truths, not current events.
- b) will rain: Used for predictions, but the command "take your umbrella" implies it is already happening.
