What are they doing for holiday?
They are happy because they are on holiday.
Mary is visiting her aunt in Paris. It is a very famous city. And it is a good place to go shopping! Tom is fishing in the lake. Because the water is very clean, there are so many fish in the lake. Simon and Bill are good friends. They are going bike riding together in the beautiful countryside (农村,乡下). It’s relaxing. Jesse is taking some photos in the park. The park is very beautiful, and it’s a good place to take photos.
It’s good for your health to have a rest. And it can help you work or study better, too. I hope everyone is having a good time.
