Reported Speech and Conditionals

Reported speech is when you explain what other people say so there are some typical changes, related to pronouns, verbs and time/place references. I think it's much more natural than what you could expect and that's the reason why you should use it in your own speech. Let's see an example:
"Yesterday I phoned my mother and she told me she didn't feel well and she asked me to go with her the following day to visit the doctor. I told her I had an important meeting at 9,30 but I was free after that time and I said I was picking her up at 10. She said she was going to make the appointment at that moment to be sure we could have the right time".
You must pay attention to the difference between TELL and SAY: the first one is used with personal complement while the second goes without it as you can see in these examples:

• Tom told her/Susan he had to work until late
• Tom said he had to work until late

Here you are some exercises to work with this: exercise 1   exercise 2    exercise 3
Remember the exception with TELL without personal pronoun: to tell the truth, to tell a lie, to tell a story/a tale, to tell a joke.

Indirect speech is related to conditionals: let's see these examples:

• she asked: Do you smoke?  ----  she asked me if I smoked
• he said: If you need money, I'll lend you some  --- he told me if I needed money he would lend some  (first conditional into second conditional)
