As a language model, I can provide you with some guidance on how to write an English essay as a primary school student. Here's a sample essay:
Title: My Favorite Animal
One reason I love pandas is because they are endangered species. It is important for us to protect them so that future generations can enjoy these adorable animals. I think it would be amazing to see a panda in person one day.
In conclusion, pandas are my favorite animal because they are unique, interesting, and need our help to survive. I hope that by protecting their habitat and working together, we can ensure that pandas will be around for many years to come.
