There is / there are

This is a lesson in your book (10A) but it's something we're going to do now as a review of the verb TO BE and to start (or continue) with the use of prepositions.

Here you are a very good link to a blog with a drawing and some exercises to practise: click here.

Remember that:

• THERE IS: singular, so you use A when it's necessary --- there's a car in the street but also you say there's (some) milk in the glass. You can say some to indicate the quantity
• THERE ARE: plural, so we say the number or a quantity --- there are some chairs or there are 3 children in the room.
