Present Continuous

Respuesta correcta: A) She reads a novel right now.

• A) She reads a novel right now.Correct. The present continuous describes an action in progress at the moment of speaking, so 'is reading' is the form the question needs.
• B) She reading a novel right now.Wrong. 'Is' and the verb must agree, so a bare 'reading' is not a complete clause; the continuous needs is plus the gerund.
• C) She read a novel right now.Wrong. The past simple would place the action at a finished moment in the past, but the phone call is happening now.
• D) She is reading a novel right now.Wrong. The simple present states a repeated or permanent habit, not an action happening at this exact moment.

Respuesta correcta: B) It is raining again.

• A) It rains again.Wrong. The simple present would describe rain as a general recurring pattern, not the rain you can actually see from the window.
• B) It is raining again.Correct. 'Look' signals that the situation is visible right now, and visible now plus a present participle gives the present continuous.
• C) It rain again.Wrong. 'Rain' cannot agree with 'it' in this construction; the continuous requires the auxiliary 'is' before the gerund.
• D) It rained again.Wrong. The past simple would be used for rain that finished earlier, but here the evidence is happening in front of you.

Respuesta correcta: C) are not working

• A) did not workWrong. 'Did not work' belongs to the past, but the arrangement described is still ahead and is a settled plan.
• B) do not workWrong. 'Do not work' states a general rule about Sundays rather than this particular week's plan.
• C) are not workingCorrect. A negative present continuous is formed with the auxiliary plus 'not' plus the gerund, which fits a fixed arrangement for Sunday.
• D) are not workWrong. After 'are not' the verb must be the gerund 'working'; 'are not work' is not a valid negative form.

Respuesta correcta: D) What are you doing now?

• A) What you are doing?Wrong. A direct question with a wh-word still needs the auxiliary and the inverted order; this version has no question structure.
• B) What did you do now?Wrong. 'Did' places the action in a completed past moment, which contradicts the idea of the current instant.
• C) What do you do now?Wrong. 'What do you do now' asks about a habit; 'now' requires the continuous form for the action in progress.
• D) What are you doing now?Correct. A question in the present continuous is built with the auxiliary am/is/are first, then the subject, then the gerund.

Respuesta correcta: A) know

• A) knowCorrect. 'Know' is a state verb, not an action verb, so it takes the simple present and never the continuous in standard usage.
• B) knowingWrong. A bare 'knowing' is not a clause on its own and cannot follow 'I' as a finite verb.
• C) am knowWrong. 'Am know' is missing the gerund; the continuous would require 'am knowing', which is the other option.
• D) am knowingWrong. Using the continuous with a state verb is ungrammatical here; states do not progress, they simply hold.

Respuesta correcta: B) He is always making the same mistake.

• A) He always makes the same mistake.Wrong. The continuous with 'always' is reserved for a habit that is annoying or surprising as it happens; here the criticism is about a repeated behaviour.
• B) He is always making the same mistake.Correct. With 'always' plus a criticism of a habit, English uses the simple present, not the continuous.
• C) He is always make the same mistake.Wrong. The auxiliary and the verb must agree, so the gerund 'making' is mandatory after 'is always'.
• D) He always is make the same mistake.Wrong. Placing 'always' in the middle of the continuous leaves the wrong participle, since the form must be 'is always making'.

Respuesta correcta: C) will be flying

• A) am flyingWrong. 'Am flying' is the present continuous, which describes now or an arrangement without the future reference.
• B) will flyWrong. 'Will fly' states the future as a simple prediction and loses the sense of an activity already under way tomorrow.
• C) will be flyingCorrect. The future continuous with a future time reference describes an activity in progress at that future moment.
• D) flyingWrong. A bare 'flying' is a gerund and cannot complete the clause 'This time tomorrow I'.

Respuesta correcta: D) am using

• A) have usedWrong. 'Have used' is the present perfect, which would show the action as finished with present relevance, not an ongoing arrangement.
• B) usedWrong. 'Used' is the past simple, but the borrowing is happening now and is still going on.
• C) useWrong. 'Use' in the simple present states a permanent or general arrangement, which is not the situation described.
• D) am usingCorrect. A borrowed vehicle for a limited period is a temporary arrangement, and English expresses temporary use with the present continuous.

Respuesta correcta: A) reading

• A) readingCorrect. 'Enjoy' is followed by a gerund in the standard pattern enjoy plus verb-ing.
• B) readsWrong. The third person plural 'reads' would be correct only if 'enjoys' were the verb, but here 'enjoy' is the main verb.
• C) to readingWrong. A gerund never takes 'to'; if the verb took an infinitive you would need 'to read' without the -ing.
• D) readWrong. 'Enjoy' is not one of the verbs that takes an infinitive after it; 'enjoy read' is ungrammatical.

Respuesta correcta: B) are listening to

• A) are listening atWrong. 'Listen at' is not a standard combination in English; the preposition that follows listen is 'to'.
• B) are listening toCorrect. 'Listen to' takes the preposition 'to', and the plural subject requires 'are' with the gerund.
• C) is listening toWrong. The singular auxiliary 'is' does not agree with the plural subject 'they', so the sentence would be ungrammatical.
• D) are listeningWrong. A verb that requires a complement needs that complement here, and 'listening' alone leaves the sentence incomplete.

Respuesta correcta: C) I called you yesterday.

• A) I call you yesterday.Wrong. 'Yesterday' belongs to the past, so a simple present verb cannot be used with that time expression.
• B) I was calling you yesterday.Wrong. The past continuous would imply a longer ongoing call being interrupted, which the sentence does not describe.
• C) I called you yesterday.Correct. 'Yesterday' is a finished past time, so the past simple is the correct choice for a single completed call.
• D) I am calling you yesterday.Wrong. The present continuous describes the present or a near future and is incompatible with 'yesterday'.

Respuesta correcta: D) is meeting

• A) has meetingWrong. The verb 'meet' is not one of those that takes a gerund; if a gerund were needed the wording would be different.
• B) metWrong. 'Met' refers to a meeting that is already over, which would contradict the idea that she is away right now.
• C) meetsWrong. 'Meets' describes a repeated or scheduled arrangement in general, not the activity happening at this moment.
• D) is meetingCorrect. 'Right now' calls for an action in progress, so the present continuous 'is meeting' explains her absence.

Respuesta correcta: A) is getting

• A) is gettingCorrect. The subject 'the bus' is singular, so 'is getting off' is the correctly spelled third person continuous form.
• B) am getWrong. 'Am get' is missing both the singular agreement and the -ing ending required in the continuous.
• C) gettWrong. A truncated spelling without the -ing ending is not a verb form at all and cannot follow an auxiliary.
• D) are gettingWrong. 'Are getting' would be the form for a plural subject or for 'you', but here the subject is the singular 'bus'.

Respuesta correcta: B) are hurrying

• A) hurryWrong. 'Hurry' in the simple present gives a general instruction, not the action in progress right now.
• B) are hurryingCorrect. The plural subject 'they' takes 'are hurrying', and the action is happening at this moment.
• C) hurryingWrong. 'Hurrying' on its own is a gerund and cannot function as the finite verb of the clause.
• D) is hurryWrong. 'Is hurry' combines a singular auxiliary with a bare infinitive, which is not a valid form.

Respuesta correcta: C) She is walking up and down the corridor.

• A) She walk up and down the corridor.Wrong. A bare 'walk' with a third person singular subject cannot follow the pronoun 'she' in the present.
• B) She walks up and down the corridor.Wrong. The simple present would turn the movement into a repeated routine or a general pattern of behaviour.
• C) She is walking up and down the corridor.Correct. Movement limited to one area and continuing at the moment is described with the present continuous.
• D) She walked up and down the corridor.Wrong. 'Walked' places the movement in a finished past moment, which does not match the ongoing observation.

Respuesta correcta: D) are meeting

• A) metWrong. 'Met' refers to a meeting that has already taken place, so it contradicts the future appointment.
• B) will meetWrong. 'Will meet' can suggest a spontaneous decision, whereas a diary entry signals a prearranged appointment.
• C) meetWrong. 'Meet' in the simple present would describe a general habit of meeting the head teacher.
• D) are meetingCorrect. A fixed future arrangement between people is expressed with the present continuous, not the future 'will'.

Respuesta correcta: A) Look, it is snowing in August.

• A) Look, it is snowing in August.Correct. 'Look' points to what is visible at this moment, and the surprising weather makes the present continuous appropriate.
• B) Look, it snow in August.Wrong. 'Snow' without an auxiliary or proper agreement is not a finite verb and cannot complete this clause.
• C) Look, it snowed in August.Wrong. 'Snowed' reports a past event, but the speaker is observing the snow as it falls.
• D) Look, it snows in August.Wrong. 'Snows' would present the snowfall as a normal repeated pattern, which loses the sense of surprise.

Respuesta correcta: B) She is waiting for you in the lobby.

• A) She waits for you in the lobby.Wrong. 'Waits' describes her general routine rather than her current activity, which is what the report needs.
• B) She is waiting for you in the lobby.Correct. The action is still continuing at the time of speaking, so the present continuous reports where she is now.
• C) She is wait for you in the lobby.Wrong. 'Is wait' lacks the gerund; the continuous must be 'is waiting'.
• D) She wait for you in the lobby.Wrong. A third person singular subject requires 'waits', 'wait' or the auxiliary 'is'; a bare 'wait' is not correct.

Respuesta correcta: C) I am reading and she is writing a letter.

• A) I read and she is writing a letter.Wrong. Only the second clause is in the continuous; the first uses a simple present that does not match the moment.
• B) I read and she write a letter.Wrong. 'I read' and 'she write' are simple present forms that describe habits, not what is happening now.
• C) I am reading and she is writing a letter.Correct. Both actions are in progress at the moment of speaking, so each clause uses the present continuous with correct agreement.
• D) I am read and she writing a letter.Wrong. 'Am read' and a bare 'writing' both lack the required gerund and agreement.

Respuesta correcta: D) She usually cooks at home, but today she is eating out.

• A) She cook usually at home, but today she is eating out.Wrong. 'She cook usually' misplaces the adverb and uses a bare infinitive after a third person singular subject.
• B) She usually is cooking at home, but today she eating out.Wrong. The continuous cannot sit before 'usually' in this order, and 'she eating out' lacks the auxiliary.
• C) She usually cooks at home, but today she eats out.Wrong. Using the simple present for the temporary case removes the contrast between a habit and a one-off activity.
• D) She usually cooks at home, but today she is eating out.Correct. 'Usually' introduces the habit with the simple present while 'today' introduces the temporary action with the present continuous.
