Hello to you all.
Some days ago my English teacher confused me a bit with this subject. I had always thought that future in the past was made of "would" + base form of a verb.
Instead, she explained us that when thinking an action is still possible that happens, English uses the above-mentioned construction, but, when thinking something is no more possible that happens, English uses "would have" + base form of a verb. I'll give two examples:
1) "It's 11 o' clock. Doesn't Peter come?" - "He will be probably late. He said that he
would come" (still possible).
2) Peter said that he
would have come, but he had to give up (no more possible).
So, just to clarify every doubt, is all that true?
Thanks in advance.
