All others are fine.

What answers are you expecting for each one?

To complete these sentences, you need to choose whether to use the gerund form (-ing) or the infinitive form (with or without "to") of the verbs in brackets. Here's a breakdown for each sentence:

1. She swore (tell) __________ the truth.
To determine whether to use the gerund or infinitive form after "swore," think about whether the verb expresses an action or an intention. In this case, "tell" is an action verb, so we should use the gerund form: telling. The sentence becomes: She swore telling the truth.

2. She mentioned (move) __________ into a new house.
Similarly, "mentioned" is an action verb, so we should use the gerund form: moving. The sentence becomes: She mentioned moving into a new house.

3. The teacher postponed (write) __________ the test.
"Postponed" refers to delaying an action, so we should use the infinitive form: to write. The sentence becomes: The teacher postponed to write the test.

4. She always avoids __________ (be questioned).
After "avoids," we need to consider whether the verb that follows is an action or a state. In this case, "be questioned" is a state of being rather than an action, so we should use the gerund form: being. The sentence becomes: She always avoids being questioned.

5. It will be difficult for me (finish) __________ my project work by tomorrow.
Here, we have a future reference. To express future intention, we should use the infinitive form: to finish. The sentence becomes: It will be difficult for me to finish my project work by tomorrow.

6. I can't help (think) __________ how beautifully Jane sings.
After "help," we commonly use the gerund form. The sentence becomes: I can't help thinking how beautifully Jane sings.

7. Did you remember (lock) __________ all the doors?
"Remember" is followed by an action, so we use the infinitive form: to lock. The sentence becomes: Did you remember to lock all the doors?

8. He has given up (play) __________ chess.
"Given up" indicates stopping an action. We should use the infinitive form: to play. The sentence becomes: He has given up to play chess.

9. I finished (type) __________ the letter a minute ago.
"Finished" is followed by an action, so we use the gerund form: typing. The sentence becomes: I finished typing the letter a minute ago.

10. The boss threatened (fire) __________ me unless I obeyed him.
"Threatened" is followed by an action, so we use the gerund form: firing. The sentence becomes: The boss threatened firing me unless I obeyed him.

10. We regret (inform) __________ you that you failed your test.
"Regret" is typically followed by an action, so we should use the gerund form: informing. The sentence becomes: We regret informing you that you failed your test.
