Hi platformreg,

I'm afraid it's difficult to generalise about this. If you'd like to send a few specific sentences, we'd be happy to take a look at them for you, and remember the dictionary, which I think could be a big help. Once you've identified how verbs go with prepositions, then be sure to make a note of them so that you can refer to them in the future.

Best wishes,

can we use "which is too far from me" , and why we are using which there?

Hello muntaziri,

That is a possible phrasing, yes, but it is hard to say more than that without seeing it in context.  Perhaps you could post the sentence in its full context (the whole sentence, and any other sentence which came before it in the text or dialogue in which is appears), and then we will be able to comment more fully.

I was wondering what do you call "general question"? Please I can't see the differences.

Hi tenchi91,

A general question is one which is not about a limited set.  For example, if I ask 'What is your favourite film?' then I am asking a general question and you can choose any film at all.  If I ask 'Which is your favourite film?' then I am asking about a certain group of films - for example the films which are on at the cinema at the moment, or the films I can see in a shop.  The context should make it clear which group you are referring to.

I hope that clarifies it for you.

Best wishes,

May I know past perfect tense please? How can i use it? thank you.!!!

Hello Bo Bo Naing Win,

You can find a page with information on the past perfect and an exercise to practise it here.

I also like to ask you to please post your comments on related pages.  This page is about interrogative determiners, not verb forms, so your question does not match the topic.  It's useful for everyone to be able to see questions and answers  which are relevant to whatever they are learning, so please try to find a relevant page to post each question on.

Thank you and best wishes,

Hi monaluki,

I suppose that you are asking about relative pronouns. Please take a look at our relative pronouns page, and then if you have any questions, please don't hesitate to ask us there.

I would like to know which determiner I should use when in the below situation.
1. in a bookshop or in a cinema
    Which is your favourite book? or What is your favourite book?
   To my knowledge, when we're in bookshop, there're numerous books thus the options are many and we can use determiner 'what'. Also I'd like to know whether there's a specific number associated as a condition to use 'Which'. For an example, if I can see lesser than 4 items, I can use 'which' or anything as such. Can you explain this?
