Read the sentence.

Leslie would probably have come with us if she didn’t work all summer.

Which is the verb phrase?

a would probably have come

b would have come

c Leslie would

d with us

c Leslie would

The verb phrase in the sentence is "would probably have come" (option a).

To identify the verb phrase in the sentence, we need to determine the main action being described. In this case, the main action is "come".

The verb phrase is a combination of the auxiliary verb "would" and the main verb "come". It shows the conditional nature of the action.

Looking at the options provided:

a) "would probably have come" - This is the complete verb phrase.

b) "would have come" - This is the same verb phrase as option a, just without the word "probably".

c) "Leslie would" - This is not the complete verb phrase, as it does not include the main verb "come".

d) "with us" - This is a prepositional phrase, not the verb phrase.

Therefore, the correct answer is option a) "would probably have come".
