With a third-person singular subject in the present simple, the verb takes -s or -es. 'My sister' is third-person singular, so 'goes' is the correct present simple form.
'Time' is an uncountable noun, so it takes 'much' in negative and question contexts. 'Many', 'a few' and 'several' only modify countable plural nouns.
For longer adjectives, the comparative is formed with 'more' plus the adjective, followed by 'than'. 'Interesting' has three syllables, so 'more interesting' is correct.
The phrase 'look forward to' ends in a preposition, so it is followed by a gerund (-ing form). Therefore 'to seeing' is correct.
In the present simple negative, we use 'doesn't' plus the base form of the verb for third-person singular subjects. The main verb stays in its base form after 'doesn't'.
'Generous' describes someone who gives freely; its opposite is 'mean', meaning unwilling to give or share. The other options describe different qualities rather than the opposite of generous.
In 'there is/are' sentences, the verb agrees with the noun that follows. 'Students' is plural and the time is past, so 'were' is correct.
In first conditional sentences, the if-clause uses the present simple, while the main clause uses 'will' plus the base verb. So 'rains' is correct after 'if'.
'Ever been' signals the present perfect, which is formed with 'have/has' plus a past participle. For 'you', the correct auxiliary is 'Have'.
In reported speech, a past event that happened before the reporting verb is expressed with the past perfect. 'The night before' points to an earlier time, so 'had seen' is correct.
The passive voice is formed with the correct form of 'be' plus a past participle. The action happened yesterday, so the past simple passive 'was broken' is needed.
The pattern 'so + adjective + that' expresses a result. 'Tired' is an adjective, so 'so' is correct.
A relative pronoun that refers to a person and acts as the subject of the clause is 'who'. 'The teacher' is a person and is the subject of 'helped'.
The past perfect describes an action completed before another past action. The concert began before 'we arrived', so 'had started' is correct.
'Should' gives advice or a recommendation, which fits a warning about possible rain. The other modals express possibility, ability or hypothetical situations rather than advice.
The indefinite article 'an' is used before a vowel sound, and 'elephant' begins with a vowel sound. Therefore 'an elephant' is correct.
The structure 'would rather' is followed by the bare infinitive (base verb). So 'stay' is correct, and it pairs with 'than go out'.
Adjectives ending in -ed describe how a person feels, while -ing adjectives describe the thing that causes the feeling. The speaker's feeling is described, so 'bored' is correct.
When reporting a yes/no question, we use 'if' or 'whether' to introduce the reported clause. The original question was 'Have you finished your homework?', so 'if' is correct.
The correlative conjunction 'neither' pairs with 'nor'. So 'neither ... nor' is the correct combination.
A direct question inside quotation marks keeps its question mark before the closing quotation mark, and the reporting clause follows outside. This makes the second option correct.
When a sentence begins with a negative or restrictive adverb like 'hardly', the subject and auxiliary are inverted. The past perfect auxiliary 'had' comes before the subject, giving 'had I closed'.
This is a third conditional sentence, which describes an unreal past situation. The if-clause uses the past perfect ('had known') and the main clause uses 'would have' plus a past participle.
In a participle clause, the subject of the participle must be the same as the subject of the main clause. In 'Walking home, I was caught in the rain', 'I' is the one walking, so the sentence is correct.
Collective nouns like 'committee' are usually treated as singular in formal British and American English when acting as one body. The pronoun 'it' later in the sentence confirms the singular view, so 'is' is correct.
We use 'both' to refer to two people or things together. 'Both of them' means the two brothers. 'Either' and 'Neither' are used for one of two, and 'Each' is used for individual members, not the pair as a whole.
For comparative sentences with 'than', we use the comparative form of the adverb. The comparative of 'beautifully' is 'more beautifully'. The superlative 'most beautifully' is used for three or more, and 'as beautifully' is used in equal comparisons.
The expression 'look forward to' is followed by a noun or a gerund (-ing form). Here, 'to' is a preposition, so the verb after it must be in the -ing form: 'to seeing'. The other options use the wrong preposition or verb form.
The sentence describes the teacher's character, so we need an adjective with a positive meaning. 'Helpful' means willing to help, which fits the context. 'Helpless' means unable to help oneself, which is negative and does not fit.
The sentence describes an ongoing action in the past that was interrupted by another action. The past continuous tense is formed with 'was/were' + -ing. Since 'children' is plural, we use 'were'. 'Was' is singular, and the present forms do not match the past context.
The verb 'deny' is followed by a gerund (-ing form), not an infinitive. So 'denied breaking' is correct. The other options use the wrong verb form after 'deny'.
We use 'on' to show that something is resting on a surface. A book on a table is in direct contact with the surface. 'In' means inside something, 'at' is used for points or places, and 'by' means beside.
We use 'since' with a point in time (2010) and 'for' with a period of time (ten years). The present perfect 'has lived' is used for an action that started in the past and continues to the present. The other options use the wrong preposition or tense.
Question tags use the opposite polarity of the main clause. The main clause is negative ('haven't'), so the tag must be positive ('have you'). The auxiliary 'have' is repeated, and the subject is 'you'.
This is a second conditional sentence, which uses the past subjunctive 'were' for all subjects in the if-clause. 'Were' is the correct form here, even with 'I'. The other options are not used in this hypothetical structure.
The verb 'suggest' is followed by a gerund (-ing form) when there is no indirect object. So 'suggested going' is correct. The other options use the wrong verb pattern after 'suggest'.
We use 'an' before a vowel sound, not just a vowel letter. 'Honest' begins with a vowel sound because the 'h' is silent, so 'an honest man' is correct. 'A honest' is wrong because 'a' is used before consonant sounds.
The sentence is passive because the subject 'report' receives the action. The past simple passive is formed with 'was/were' + past participle. 'Was written' is correct. The other options are active forms or the wrong tense.
When a sentence begins with a negative adverb like 'hardly', the subject and auxiliary verb are inverted. The past perfect 'had closed' is used because the action was completed before another past action. So 'Hardly had I closed' is correct.
When two past events are contrasted, the earlier one takes the past perfect (had + past participle), and 'by the time' signals that the finishing happened before the arrival. The later event ('we arrived') stays in the simple past. Present perfect cannot be used because there is no connection to the present moment.
The text lists a sandwich and an apple as the items she put in her bag, and both are food. Water is a drink, not food, and the other items are not mentioned. So the food items are the sandwich and the apple.
The phrase 'every day except Monday' means all days are open apart from Monday. Therefore Monday is the day it is closed. The other days are included in 'every day'.
The text says Tom did not have enough money for a bike and then chose to wash cars to earn some. This shows his reason was to get money for the bike. The other reasons are not stated.
The text gives the reason directly: bread is bad for the ducks. Making the water dirty is an extra point, but the harm to the ducks is the central reason. The other options are not supported.
The text says 'Everyone must bring a packed lunch'. The comfortable shoes are something to wear, not to bring. The other items are not mentioned.
The word 'so' introduces the purpose: meeting early allows time to warm up. The other reasons are not given in the text. The match time is separate from the meeting time.
The text gives its location as next to the science lab. It also says it is on the second floor, which rules out the first floor. The other places are not mentioned.
The text states the teacher asked him to finish it at break time. The word 'so' shows this is the result of forgetting it. The other times are not mentioned.
Dark clouds and taking an umbrella are clues that rain is likely. The text gives no information about heat, snow or wind. Readers use these clues to guess what may happen.
'Closed for repairs' plus 'open again on Monday' means it stays closed until Monday. It is not just for one day unless today is Sunday. The text does not say the shop moved or is open all week.
