English: Tenses MCQ - Practice Questions with Answers

In first conditional sentences, the if-clause uses the present simple tense, while the main clause usually uses "will" plus the base verb. So "If he comes on time, we will start" is correct. The same rule applies to future time clauses beginning with words such as "when". We say "When the result is declared, I will inform you", not "when the result will be declared". Therefore, only sentences I and III are correct.

In a first conditional sentence, a real future condition is expressed with the simple present in the if-clause and 'will' in the main clause. Sentence I follows this pattern: 'If it rains, the match will be cancelled.' Sentence II is wrong because 'will' is not normally used in the if-clause for this structure. Sentence III is also wrong here because 'rained tomorrow' does not match the main clause 'will be cancelled'. Therefore, only sentence I is correct.

The phrase “an hour ago” requires the simple past, so “left” fits the first blank: he left home an hour ago. The word “yet” in a negative sentence points to the present perfect, so “has not returned” fits the second blank. “Leave, not returned” lacks the needed finite past verb and auxiliary. “Leaves, didn’t return” wrongly uses the simple present with “ago” and the simple past with “yet”. “Will have, has not returned” is grammatically unsuitable because “will have home” does not express leaving.

This is an incorrect-sentence question, so the answer is the sentence with the tense error. "Since 2020" gives a starting point in the past and shows that the situation continues up to the present. Standard usage needs the present perfect tense: "I have lived in Jaipur since 2020." The present continuous "am living" does not correctly express this continuing duration from a starting point. The other sentences correctly use present perfect with "for", "since", or "already".

When two past actions are mentioned, the action completed earlier is usually put in the past perfect tense. Here, the rain stopped before the bus reached the village. The later past action is expressed by "reached", and the earlier completed action must be "had stopped". Present simple and present perfect do not fit this past time frame, and past continuous suggests an action in progress, not a completed earlier action.
