RevisionIt's so hot today — let's go swimming in the lake after lunch.
Go to swim can look logical, since go to + place is so common. But for activities like swimming, shopping or running, English uses go + -ing: go swimming, go shopping, go running. So to swim was replaced with swimming.
Let's is short for let us, but in everyday speech the full form sounds different. Let us go! is most often heard as “release us”, and to suggest going somewhere, people say only let's. The full let us survives in formal speeches and prayers: Let us pray.
