Shichi-go-san is a Japanese festival. The Japanese celebrate it on 15 November every year. This is because people believe it is a day of good luck for all Japanese people.

Shichi-go-san means “seven-five-three” and the festival is for children who are seven, five and three. The Japanese think these ages are very important years. Japanese parents celebrate Shichi-go-san as their boys turn three and five and their girls turn three and seven.

At the age of seven, a girl wears obi - the piece of cloth worn round the waist over the kimono - for the first time. At the age of five, a boy wears his first hakama pants – the pants that Samurai wore in the past - in public. The age of three is important for the Japanese too.They think it is time children can let their hair grow.On this day, children often dress up like the adults in the ancient times and pretend to be grown up themselves.

I.    Put the words in the box into two groups.

Our school has an organic garden. We learn about growing vegetables and looking after them in our food science lessons. In the holidays, we can volunteer to work in the garden. My family live in a flat so it’s great for me to have a garden at school. Volunteers can take some vegetables home too, so my parents are very happy that I like working there.

My aunt and uncle live on a farm in the Red River Delta. It isn’t very big but they have hens, pigs, and cows. We always go to stay with them in summer. It’s a beautiful place and the food is amazing. All the vegetables are so fresh and, because the farm is organic, we know they are healthy, too.

We live in Ha Noi and my parents buy food at The Viet Fresh Farm Shop near our flat. It is very famous in our city and all the food they sell is from animals that live on the farm or vegetables that they grow. They organise a food festival once a year and we always go to eat the free food and watch cookery demonstrations. They are really interesting and you can learn a lot about cooking.
