Tenses — Present (simple/continuous/perfect/perfect-continuous) MCQ — 14 Practice Questions with Answers

Explanation

Use the simple present tense for habits, routines, and regular schedules. The cues "usually" and "on working days" show a normal schedule, not an action happening now or a completed action. Since "post office" is singular, the verb takes -s: "opens" is the only correct choice.

Explanation

The present continuous is formed with am/is/are + the -ing form and is used for an action happening now. The cue "right now" requires an in-progress action. With the singular subject "clerk", the correct auxiliary is "is", so only "The clerk is checking the files right now" is correct.

Explanation

Present perfect continuous is used for an action that started in the past and continues now, especially when duration is important. Statement 1 gives this rule, and Statement 2 gives the correct time cues: "since" marks a starting point and "for" marks a length of time. Therefore, both statements are correct, and option B is the correct choice.

Explanation

The simple present is used for habits, routines, and fixed schedules. The cue 'usually' marks the first clause as a routine, and the singular subject 'The office' takes the -s form: 'opens'. The later phrase 'today it is opening' only describes a temporary change, so 'opens' is the only correct choice for the blank.

Explanation

The present perfect can express a completed action with a present result or relevance. The cue is the form 'has gone', which is 'has' plus the past participle. In 'The peon has gone to the store room', the sentence points to a present result, such as his being away from the desk now. Since R states this rule and directly explains A, option A is the only correct choice.
