1. He says he will work all tomorrow evening.
Explanation: In this sentence, we have the verb "to work" in the base form. However, since it is talking about a future action, we need to use the future tense. To form the future tense in English, we use the auxiliary verb "will" before the base form of the main verb. So the correct answer is "will work".

2. Alex said they would return by the end of the week.
Explanation: In reported speech, when reporting something that was said in the past, we usually need to shift the tenses back. So the verb "to return" changes from the present tense to the past tense. We use "would" before the verb to indicate the past tense. Therefore, the correct answer is "would return".

3. Sue thought Mary would be late.
Explanation: Similar to example 2, in reported speech, the verb tenses are usually shifted back. In this case, the verb "to be" changes from the present tense to the past tense. The correct answer is "would be".

4. Nick is sure Brian will have worked for some hours when he comes.
Explanation: In this sentence, we have a future action ("when he comes") that will be completed before another future action ("will have worked"). To express this in English, we use the future perfect tense. We use "will have" before the past participle form of the verb. So the correct answer is "will have worked".

5. They believe we will not refuse them.
Explanation: In this sentence, we have a negative statement ("will not refuse"). To form the negative future tense in English, we use the auxiliary verb "will" followed by "not" before the base form of the verb. So the correct answer is "will not refuse".

6. We were sure Ed would phone us in some days.
Explanation: Similar to example 2 and 3, in reported speech, the verb tenses are shifted back. In this case, the verb "to phone" changes from the present tense to the past tense. The correct answer is "would phone".

7. Philip understood he would not finish work by eight o'clock.
Explanation: In this sentence, we have a negative statement ("would not finish"). To form the negative future tense in English, we use the auxiliary verb "would" followed by "not" before the base form of the verb. So the correct answer is "would not finish".

8. We know we will not go out if it rains.
Explanation: Similar to example 5, we have a negative statement ("will not go out"). To form the negative future tense in English, we use the auxiliary verb "will" followed by "not" before the base form of the verb. So the correct answer is "will not go out".

9. I heard he had been appointed to a new position.
Explanation: In reported speech, when reporting something that was said in the past, we usually need to shift the tenses back. In this case, the verb "to be appointed" changes to the past perfect tense. The correct answer is "had been appointed".

10. Ewa knew they cared about her child well.
Explanation: In this sentence, we have the verb "to care" in the past tense. The correct answer is "cared".
