Hello, can anyone help me with the following please?
Determine what the most likely grammar point will be in each of the following and summarize or define it.
A. I would go if I had the time.
B. What have you done with your hair?
C. That sign was just painted.
D. He could have phoned but I doubt it.
E. She´ll have finished by the time we arrive.
A. I would go if I had the time.
I suspect this is meant to be an example of the conditional mood. Most native English speakers will naturally form it correctly.
B. What have you done with your hair?
This is an example of an interrogative sentence (ie a question).
C. That sign was just painted.
This is an example of a passive sentence.
D. He could have phoned but I doubt it.
This may be showing an auxiliary verb being followed by an infinitive verb without "to".
E. She´ll have finished by the time we arrive.
This is likley designed to be an example of the future perfect tense (perfect aspect). See here for details.
