Lesson twenty seven

Here you are giving an example of what decision YOU would do given the circumstances. This can be in past tense or in a conditional present.

Here are some examples:

"If I were you, I would enjoy my vacation."
"If I were you, I would explain what happened."
"If I were you, I would continue working until it is done."
"If I were you, I would book my reservations now."
"If I were you, I would answer the question."

By adding 'have' after the word 'would' you are talking about something in the past tense.

Here are some examples:

"If I were you, I would have enjoyed my vacation."
"If I were you, I would have explained what happened."
"If I were you, I would have continued working until it was done."
"If I were you, I would have booked my reservations now."
"If I were you, I would have answered the question."

"It's going to be exciting."
"It's going to be disgusting."

"He is going to be tough to deal with."
"He is going to be terrific at that."
"She is going to be relieved to hear that."
