This is correct sentence about "which" as given below:
1.This is plus point for the children which they can fulfil their needs.

Hello Mohsin Abbas,

No, that sentence is not correct. Without knowing the exact context it is hard for me to be sure what the correct sentence should be, but I would guess one of these is what you need:

This is a plus point for the children, who can fulfil their needs.

This is a plus point for the children, which enables them to fulfil their needs.

so good

Hello teachers! Should I use "how" or "what" in this sentence: "She never tells us _______ she feels." I feel it should be "how" more than "what" but the more I think about it, the less sure I am. Is it idiomatic? Or does it depend on the verb?
1. She never tells us how she feels.
2. She never tells us what she thinks.

Hello Kurin,

Both 'how' and 'what' are possible here. It does depend somewhat on the verb. When we use 'feel' we can can say 'how' or 'what', but when we use 'think' we can only use 'what'.

This is not a question of idiomatic meaning but rather collocation - which words go with other words in common use. Just as we usually say 'heavy rain' rather than 'strong rain' but 'strong wind' rather than 'heavy wind', so we use 'how' and 'what' as described above.

Collocation - that's the word! Okay, thank you!

I´m very happy with this kind of study! Congratulations to all team of the Learnenglish British Council!

Thank you so much sir, you solved my confusion, and thank's for co-operation.

Whats the difference between word especially and specially? can you tell me the appropriate use of it.

Hello Imran,

I'd recommend you two resources: one is the dictionary (see the search box under Cambridge Dictionaries Online on the lower right side of this page), where you can see definitions and examples of both words. Another good resource is this archived page on the BBC's Learning English site.

All the best,
