Hello,

In the lesson, you say to use "in" when talking about "lake," but in Grammar Test 2, line 5, you say, "5. Last summer we stayed in a cabin on a lake."

Is this a mistake, or why do we say "...on a lake" instead of "...in a lake"?

Thank you

Hello Ama1,

'In' describes actually being in the water, so you can swim in a lake, for example.

'On' is used in two ways. First, it is used for activities which are on the surface of the water, so you can sail on a lake or waterski on a lake. 'On' can also be used to describe the location of a place, so you can say it is a house on a lake, meaning beside. It's similar to 'on the coast' or 'on a river'.

In this sentence, the correct option is "because it is played inside the park."

Let’s play football in the park

Hi teacher

Let's play football (in or at )th park. 

Which one is true or both this.

 

Hi 20414641,

I think both are perfectly fine here. At could mean inside or nearby (at the entrance or just outside, for example), but since you are playing football I don't think there is any ambiguity so you can use either.
