We must complete the sentences with the verbs that appear in the schedule. The tense that must be used is the Present Continuous. We can do it as follows:
1. is buying / is meeting
2. are cleaning / they are polishing
3. is calling / is installing
4. is sending / is tidying up
5. they are painting / they are preparing
The sentences in the question use to Present Continuous tense to talk about future plans.
The structure of the Present Continuous tense is:
subject + to be (present) + verb -ing
In negative sentences, we add "not" after the verb "to be". It can also be contracted with the verb.
In interrogative sentences, we place the verb "to be" before the subject.
Examples:
- affirmative: She is redecorating her house.
- negative: She isn't redecorating her house.
