Additional Cases when to use Future Simple

Let’s look at some more interesting cases where we can use Future Simple.

Will + Have To

We use have to and the Future Simple to express that someone must do something in the future. Such sentences are based on the following scheme:

Subject + will + have to + verb + rest of the sentence


You will have to visit the doctor next week.

He will have to tell her the truth.

How to from and example of use will have to.
Will Have To.

Will and Indirect Question

Let’s take a look at another interesting case where we can use will. It happens when we form a subordinate clause that begins with the conjunction if or the conjunction whether. This is called an indirect question. Although there is no question mark or question word order in such sentences.

Such indirect questions are similar to conditional sentences. But in fact, indirect questions with the conjunctions if or whether ARE NOT conditional clauses.

Conditional clauses have a condition and a result. In indirect questions, there is no condition or result. In such questions, there is an alternative to what might happen. Take a look at examples:

I doubt if he will accept my advice.

I am wondering if he will carry off the prize.

We’ve come to ask the king if he will grant mercy.

I don’t know if he will visit us next Sunday.

Maggie wonders if she will share their fate.

I don’t know if she will be happy about that.

When to Use Will as Modal Verb?

It is one more way how we can use will. However, this has nothing to do with the future. Because in this case, we use will not as an auxiliary verb, but as a modal.

We use will as a modal verb to indicate that someone is unwilling to do something. Such an action refers to the present time, not to the future! Take a look at examples:

I feel angry with him because he won’t let me live my life.

I tried, but for whatever reason, he won’t let me help him.

I’m doing all I can, but she won’t talk.

Note: In colloquial speech, we emphasize the modal verb will with our voice making it clear that we are using will exactly as a modal verb.
