перевод текста Watching Wildlife:Hello everyone! It's nine o'clock in the morning. I've been at the National Marine Aquarium for the whole night! The National Marine Aquarium is in Plymouth and it's the biggest aquarium in the UK. It's been open since 1998 and it works hard to protect ocean wildlife. You can see lots of fish and other sea creatures at the aquarium. I've loved the ocean since I was little, and last night my dad and I spent the night in the aquarium to learn more about the amazing species there. It's called the Sleeping With Sharks experience. We saw sharks, octopuses and clown fish, and we learnt lots of interesting things about them. I loved Snorkel, the Loggerhead Turtle. She's lived at the aquarium for about 25 years. We made models or painted pictures of our favourite sea creatures in the arts and crafts centre. I made a model of Snorkel. Then we watched a film about a turtle on a big 4D screen. The screen blew air at us and sprayed water in our faces! It was really cool! We got into our sleeping bags in front of a huge fish I've tank. We had a snack and then we fell asleep while the fish swam around us. had a brilliant time! Finn, age 11​

My favourite film
I really love to watch films. We often go to the movies with our parents or friends. Usually I like historical films or cartoons. Mom loves movies about love, and dad loves movies about superheroes. Recently my whole family has watched the movie "Hachiko". This is a story about true friendship between a man and a dog, based on real events. One day a man named Parker found а puppy at a train station. The puppy became a kind and friendly and loved Parker most of all. They have spent a lot of time together. The dog went with his friend to the station when he went to the university to lesson. In the evening he met the train in which Parker returned home. It was their tradition, this continued for a long time, until the bad situation happened. Parker died at the lecture from a heart attack. Hachiko still came to meet him, but no one came. From this moment the saddest part of the story begins. Parker's family tried to take the dog to their house, but he left at the station, where he continued to wait for his friend. He waited for him for ten years and died in this place, as an example of endless love.

1. We often go to films with friends and parents.
