GRAMMAR

First Conditional

After a reasonable possibility of condition, we use present or future actions. We are going to see four types.

Type 1:

a. If we rent a house, we will sign an agreement.

If-clause (S. Present)               Main-clause (future)

b. If she rents a room, she will have to respect the rules.

If-clause (S. Present)                Main-clause (future)

Note: We can use these sentences starting from the main-clause. In that case, don’t use comma (,).

Examples:

a. We will sign an agreement if we rent a house.
b. She will have to respect the rules if she rents a room.

Type 2:

a. If we are expecting visitors, we will cook delicious dishes.

If-clause (P. Continuous)               Main-clause (future)

We will cook delicious dishes if we are expecting visitors.

b. If she is studying Chinese, she will travel to Asia.

If-clause (P. Continuous)                Main-clause (future)

She will travel to Asia if she is studying Chinese.

Type 3:

a. If you don’t have a DVD player, you can’t see the movies.

If-clause (S. Present)                         Main-clause (modals)

You can’t see the movies if you don’t have a DVD player.

b. If Henry is going to a job interview, he should wear a suit.

If-clause (P. Present)                          Main-clause (modals)
