Grammar explanation

Future continuous

We can use the future continuous (will/won't be + -ing form) to talk about future actions that: 

  • will be in progress at a specific time in the future:

When you come out of school tomorrow, I'll be boarding a plane.
Try to call before 8 o'clock. After that, we'll be watching the match.
You can visit us during the first week of July. I won't be working then.

  • we see as new, different or temporary:

Today we're taking the bus but next week we'll be taking the train.
He'll be staying with his parents for several months while his father is in recovery.
Will you be starting work earlier with your new job?

Future perfect

We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future.

The guests are coming at 8 p.m. I'll have finished cooking by then.
On 9 October we'll have been married for 50 years.
Will you have gone to bed when I get back?

We can use phrases like by or by the time (meaning 'at some point before') and in or in a day's time / in two months' time / in five years' time etc. (meaning 'at the end of this period') to give the time period in which the action will be completed.

I won't have written all the reports by next week.
By the time we arrive, the kids will have gone to bed.
I'll have finished in an hour and then we can watch a film.
In three years' time, I'll have graduated from university.

Hi,

I need some help with these;

If there is spillage, do not use the broom until the spill "is cleaned."

spill is cleaned or has been cleaned?

Another example would be;

Make sure the equipment "has dried/is dry/is dried" after cleaning.

Thank you.

Hi cadbury555,

In the first case you mention, I, like you, think that has been cleaned is more precise - it makes it clear that the spillage should no longer be present before the broom is used. Sometimes in subordinate clauses, verb tenses are simplified if the time is already clear from the form of the main verb. In this case, the time is not all that clear from the main verb, but it seems that whoever wrote this simplified the verb in the subordinate clause anyway. This sometimes happens, as the meaning is fairly evident, but has been cleaned would be more clear.

The second case is similar in some ways, though is dry and is dried are different contructions because they are not verbs but rather a verb (is) plus an adjective (dry or dried). As you can see in the dictionary, dried is normally used to refer to flowers or fruit and dry is used in the more general sense. Thus is dried in this sentence is perhaps strictly speaking not correct, but given the context, the meaning is clear.

I hope that helps.

thank you very much. daily i read a lot.

What is the actual meaning of these two sentences :---- "I don't do that" &&& "I won't do that" .

now as far as I know , both these sentences are grammatically correct . but I have some confusion regarding the actual meaning of these two sentences .What is the difference of meaning ?

please help me , I'm eagerly waiting for the answer .

--- Shruti Aurora

Hello Shruti,

Yes, they are both grammatically correct. Their exact meaning depends on context. The first one is often used to speak about daily habits, whereas the second one could be used, for example, to make a promise not to do something. I'd suggest that you look at our pages on the present simple and will and would for detailed explanations and examples of both forms.

Hi there! I want to ask about the prepositional phrase " at first". At is a preposition, so first is a noun or a pronoun? 

By the way, you can find more information on prepositional phrases here:

Hi zhulin233,

You are correct that 'at first' is a prepositional phrase, and as such is made up of a preposition and its object, which is a noun, a noun phrase or a pronoun.  The potential source of confusion here is that 'first' is usually thought of as an adjective.  However, 'first' can be many parts of speech, including a noun.  For example:

I've never done that before so it was a first for me!

I hope that clarifies it for you.

Best wishes,

Hi,
Could you please explain the difference between the following sentences ? Thank you very much.
1) I think astronauts will land on Mars by the year 2020.
2) I think astronauts will have landed on Mars by the year 2020.

Hi sina.koohbour,

Both sentences make the same prediction. The difference is that the verb form in the second one more specifically indicates that the action of landing on Mars will already be complete by 2020. The first sentence also indicates this idea with the preposition by, but the verb form is a bit less specific.
