Hi Teacher,
How to Improve English Grammar? Tell me some easy tips. Recently I prepare from this site. can you have something more to add in this Guide.

Hello Mahi69,

I'd recommend you read our Frequently asked questions page, which has advice on how to get the most out of our site. You're welcome to study this Grammar section and our Quick Grammar to improve your grammar, but I'd also recommend you try a series like Elementary Podcasts, where you will see grammar in context and also learn vocabulary, improve your listening, etc.

All the best,

please help me... clear my doubt
i can't differentiate btw when to use "to+infinitive" and when to use "gerund" .......... a list of word given in many books to cram those word and use accordingly......... but i want to know the main concept behind it. i will read all thing please give me guidance

Hello tonystar95,

The gerund form (which is one kind of -ing form) always functions as a noun. The infinitive can have many roles in the sentence (nominal (noun), adjectival and adverbial being the most common).

You can read information on the -ing form here and on the infinitive here. Very often it is the verb which precedes these forms which determines which form is appropriate.

I hope those links are helpful. If you have any particular uncertainties then I think it would help if you provided a concrete example. It's not possible for us to explain all uses of forms in the comments sections.


Best wishes,

Would you please explain to me how and when to use 'to be' in a sentence? I often see it in sentences but not sure what does it really mean.

Hello Abidani,

It might help to think that 'to be' is an infinitive, and so, for example, as is explained on this page, it can be used after verbs like 'want' that can be followed by infinitives (e.g. 'I want to be a poet'). Infinitives are also commonly used to talk about purpose (e.g. 'I went to the market to buy some eggs').

There are so many different ways 'to be' and other infinitives can be used in a sentence that I don't think anyone could explain them all! If you find any specific examples you want ask us about, feel free to do so.

All the best,

Thank you, Kirk, for your reply.

I would be grateful if you make me clear about the use of specific 'to be' (not other infinitives or am/is.....) in sentences. For example:

''Waste water is sent to the water treatment plant to be processed.''

My query is
1) what does this sentence mean?
2) what if I don't use to be as such instead write '......................plant to process'?
3) Is it better to use such form in sentences to make them more formal or it has no impact?

Thanks again :)

Hello Abidani,

The infinitive in your example shows purpose - it tells us why the waste water was sent to the plant. You can replace 'to be processed' with 'in order to be processed' or 'so that it could be processed' without fundamentally changing the meaning. The key here is that it is an infinitive; 'be' is included because it is a passive form (to process = an infinitive; to be processed = a passive infinitive).

You can read more about this and other uses of the infinitive on this page.

You cannot use the formulation you have in your second question. You could say 'to the plant for processing', using a preposition and a gerund.

Thank you peter for the nice clarification and thanks to the @LearnEnglish team as well.

Best regards

I looked the word " postpone" up in the Cambridge Dictionary and I found that it is only used with " until", like in "The exams have been postponed until next month." My question is that would it be wrong if I use " to " with " postpone",i.e. Can I say " The exams have been postponed to next month"?

Thanks in advance,
