Mason’s father climbs the highest mountains. Mason finds his father’s work exciting. Sometimes people do not even see his father hanging on the window.

Professions are jobs that people have. Like doctors, for example. There are different kinds of doctors. If someone has a sickness, doesn't have to be a specific one, they come to a doctor. Another profession is a business man. There are loads of different ones. Some have a website of their own, some have ads all over the internet. Most of the time, they make lots of money and have other people recruited for the job.

Glad to help :)
I know all of this because I'm from England myself. I moved to Moscow 2 years ago and learned Russian, so I'm on this website now haha.

Suddenly Jane and Michael heard that somebody shut THE front door. They ran to THE window. Down, stood Mary Poppins, dressed in A coat, with A carpet bag in one hand and her umbrella in THE other. THE wind was blowind wildly about (around?) her. She smiled at THE wind and opened THE umbrella. THE wind got under THE umbrella and lifted Mary Poppins from THE ground. Then it lifted her over THE front gate and carried her over THE cherry-trees in Lane. Jane and Michael opened THE window and cried: "Mary Poppins! Mary Poppins, come back!" But she did not hear them. She went up into THE air. At last she was over THE hill and THE children couldn't see her.
