English Grammar and Usage

Since + past simple requires past simple in the main clause. Have spoken is present perfect, was speaking is past continuous, have been speaking is present perfect continuous.

The sentence is grammatically correct in formal English. 'No one but him' uses 'him' as the object of the preposition 'but' (meaning 'except'). 'The king was I' uses the predicate nominative 'I' after the linking verb 'was', following the rule that subjects and predicate nominatives match in case (subject form). While colloquial English often uses 'me' in this position, formal grammar requires 'I'.

The sentence 'He came to see ___ last night' requires an object pronoun because 'see' is a verb needing an object. Option C 'me' is the correct object pronoun. Option A 'we' is a subject pronoun, B 'he' is a subject pronoun, and D 'my' is a possessive adjective - none fit grammatically.

'Rain is coming' is grammatically correct. It uses the present continuous tense ('is coming') to describe an event that will happen soon. The subject 'rain' agrees with the verb 'is coming.'

The phrasal verb 'get round to' means to find time to do something, often after some delay or when you get around to it. It suggests you'll do it eventually when you have the opportunity. Option A correctly captures this meaning of finding time. Option B suggests completion which is different, and Options C and D add meanings not present in the original phrasal verb.

The word 'since' is used to mark the beginning of a period that continues to the present. 'Last week' is a specific point in time, which requires 'since' in the present perfect tense. 'For' is incorrect because 'last week' is not a duration.

The preposition 'since' is used to refer to a specific point in time (noon) when an action started and continues to the present. 'For' would require a duration (e.g., 'for two hours').

The question asks 'At what time do you have class?' The correct construction is 'Um wieviel Uhr' (at what time). 'Wann' means 'when' but doesn't combine with 'Uhr' in this way. The construction must include the preposition 'um' for specific times.

Option A is correct because in the subordinate clause 'who believe everything they hear', the relative pronoun 'who' is plural, so the verb should be plural 'believe'. Options B, C, and D incorrectly use singular 'believes' with plural 'who'. Also, B incorrectly uses 'these' instead of 'those', and C and D change pronoun references incorrectly.

Option A is correct because it uses consistent indefinite pronoun 'one' throughout the sentence. Options B, C, and D incorrectly switch to 'his' in the second part, creating inconsistency. The pattern 'one...one's...one likes' maintains grammatical consistency when using the indefinite pronoun 'one'.

Option B is correct because 'who' is the subject pronoun required for 'they say is the best singer'. Option A incorrectly uses object pronoun 'whom'. Option C incorrectly uses 'whom' and expands the contraction. Option D has misplaced comma spacing and should use 'who' anyway. The clause 'they say is the best singer' requires 'who' as its subject.

Option A is correct because 'each of the students' is singular, so it takes singular verb 'has'. 'Each' is always singular regardless of the prepositional phrase. Options B and D use singular 'student' instead of plural. Option C incorrectly uses plural 'have' with singular subject 'each'.
