Question

Tell him to ring me up if you saw him.correct with appropriate conditional clause.

Answer 1

Verbs in time clauses and conditionals follow the same patterns as in other clauses except:

In clauses with time words like when, after, until we often use the present tense forms to talk about the future:

I’ll come home when I finish work.

You must wait here until your father comes.

They are coming after they have had dinner.

 in conditional clauses with if or unless we often use the present tense forms to talk about the future:

We won’t be able to go out if it is raining.

If Barcelona win tomorrow they will be champions.

I will come tomorrow unless I have to look after the children.

We do not normally use will in clauses with if or with time words:

I’ll come home when I will finish work.

We won’t be able to go out if it will rain.rains.
