1. The document discusses the use of "a" vs "an" and when each is used in the English language. 2. It also covers the uses of words like "some", "any", "one", and discusses how these relate to positive and negative sentences. 3. The key rules covered include using "a" for general or new concepts and "an" for unfamiliar concepts, as well as distinctions between "some" and "any" in positive and negative sentences.

1. We use "a" or "an": 1: when we talk about something in general when we haven’t mentioned it before/ something new: I want a new coat for my birthday When we talk about something unfamiliar or unexpected to someone else I think it’s a good day to go fishing There’s an alligator in my bathroom 2: When we are describing something or saying what kind of thing it is: It’s a very hot day My husband is a vet The film was an action film

2. 3: When it means “all” An apple is a very common fruit in England ( means: all apples - we can also say: Apples are very common in England) 4 : When it means “every” in expressions of time/quantity and speed once a week/ forty kilometres an hour/ six euros a kilo When do we use “one”? When we want to emphasise the number. I want one kilo of apples I just want one book And when do we use “some”? When we are talking about things in the plural I want some apples He took some books back to the library

3. "Some" is used in positive sentences "Any" is used in negative sentences We bought a sandwich at lunchtime We bought some sandwiches at lunch time We didn’t buy any sandwiches at lunchtime And this rule carries through to when we use “ someone” or “somebody” and “anyone” or “anybody” I saw somebody with a sandwich I didn’t see anyone with a sandwich I never saw anyone with a sandwich

4. We can use both "some" or "any" in questions: We use “some” when we know or think something exists: Do you expect somebody to come? ( we think you’ll answer yes) but: Do you expect anyone to come? (we really don’t know or we expect the answer to be no) We use “any” after “if”: If anyone knows the answer - please tell me Let me know if you want anything ( often said in a shop or a restaurant) We can also use “any” if it doesn’t matter which: You can take any bus.
