Complete the sentence with one of the following verbs in the correct form: come/ get/ happen/ look/ make/ start/ stay/ try /work ‘You hard today.’ ‘Yes, I have a lot to do.’

The correct answer is: A. are working

The sentence is “You are working hard today.” This is a present continuous sentence, which means that it is describing an action that is happening right now. The verb “to work” is in the present continuous tense, which is formed by adding the present tense form of the verb “to be” (are) to the -ing form of the verb (working).

The other options are not correct because they do not form a grammatically correct sentence.

• Option B: “You are looking hard today.” This is not a grammatically correct sentence because the verb “to look” does not take the -ing form in the present continuous tense.
• Option C: “You are coming hard today.” This is not a grammatically correct sentence because the verb “to come” does not take the -ing form in the present continuous tense.
• Option D: “You have got hard today.” This is not a grammatically correct sentence because the verb “to have” does not take the -ing form in the present continuous tense.
