The verb "promised" is in the past tense. According to the rules of sequence of tenses, when the main verb is in the past, the subordinate clause usually takes a past form.

• "would work" is the correct past form of "will work."

• Other options are wrong because:

  • can work → present tense (doesn’t match).

  • will work → future (not correct after past tense promised).

  • did worked → grammatically incorrect (double past).

So the correct sentence is: "He promised that he would work hard."

In the given sentence, "She" is the subject in Passive Voice, "was given" is the verb (past simple passive), and "by the teacher" shows the doer of the action.

• To change into Active, the doer (the teacher) becomes the subject.

• The structure for past simple active is: subject + V2 + object.

• So, "She was given a prize by the teacher" changes to: "The teacher gave her a prize."

Here, "The doctor" is the subject, "will examine" is the verb (future simple tense), and "him" is the object.

To turn it into a passive sentence, the object ("him") becomes the subject ("he").

The structure for the future simple passive is: subject + will + be + past participle (V3).

So, "The doctor will examine him" becomes "He will be examined by the doctor."

The simple present tense is used to express general truths.
