6. The girls are feeding the birds in the garden while the boys are making a dying bird-house.

To understand this sentence, let's break it down step by step:

- The verb used for the girls is "feed". To make it suitable for the present tense, we add "s" at the end since the subject is plural (girls). Therefore, it becomes "feed + s = feeds". However, since the sentence is in the present continuous tense, we need to use the present participle form of the verb "feed", which is "feeding".

- In the second part of the sentence, the verb used for the boys is "make". Again, since the subject is plural (boys), we add "s" at the end to make it suitable for the present tense, which becomes "make + s = makes". However, since the sentence is in the present continuous tense, we need to use the present participle form of the verb "make", which is "making".

Therefore, the correct answer is: The girls are feeding the birds in the garden while the boys are making a dying bird-house.

7. When we came, the family is getting everything ready for decorating the Christmas tree.

Let's break this sentence down step by step:

- The verb used for the family is "get". Since the subject is singular (family), we need to use the third-person singular form of the verb, which is "gets". However, since the sentence is in the past continuous tense, we need to use the present participle form of the verb "get", which is "getting".

- The verb used for Bob and Helen is "decorate". We don't need to change anything here since "decorate" is already in the base form, and it is followed by another verb.

Therefore, the correct answer is: When we came, the family was getting everything ready for decorating the Christmas tree.

8. I did not eat ice cream when you met me in the park yesterday.

This sentence is in the past simple tense, indicating a completed action in the past. The negation "not" is used before the main verb "eat".

Therefore, the correct answer is: I did not eat ice cream when you met me in the park yesterday.

9. When I came home, Tom was not speaking over the phone.

This sentence is in the past continuous tense, indicating an ongoing action in the past. The negation "not" is used before the main verb "speak".

Therefore, the correct answer is: When I came home, Tom was not speaking over the phone.
