Dear grandma,

     How are you? I hope you are feeling well and your leg is improving. Can you walk a bit now? Is your

neighbor, Mrs Lu, bringing you enough books to read? I hope so.

     You'd love our school library, grandma. There are so many books for all kinds of subjects. The other day

I found a book about electronic engineering. I couldn't really understand it but I hope to learn more about this

topic sometime. This term I have three new subject classes, so I thought I'd tell you about them.

     I now study biology, which is really interesting. I'm learning all about the human body, where everything

is and what it does. Do you know that we have a kissing muscle? It's called 'orbicularis' (轮匝肌) and it's a

circular muscle that closes your mouth and moves your lips forward. I love biology. It's so interesting!

     Another new subject is religion. I didn't think I would like this one, but actually it is very interesting to

hear about how different people worship (崇拜). We are learning about lots of religions from all over the

world, not only Asia. Do you know about the religion on the island of Bali in Indonesia? They have a unique

religion which is based on Hinduism but also has elements of Buddhism as well. It is called Bali Hindu Dharma.

I am just learning more about it but it sounds fascinating.

     My other new subject is Spanish. It's really difficult to learn a new language but I know it will be useful

for me in the future, if I want to travel the world. Spanish is one of the official languages of the European

Union and the United Nations. I've learnt that Spanish is not only spoken in Europe but in South America, too.

Countries like Peru, Bolivia, Chile and Mexico also speak Spanish. You know I've always wanted to go to

Mexico, so if I can speak some Spanish it would be really useful.

     Did you study these subjects when you were at school? I suppose subject choice changes over time,

doesn't it? I'll come to visit you again in the next holiday, which I think is in eight weeks' time. I'll bring you

some of my new books if you like. I hope you can write back soon and tell me all the village news. I miss you

very much.

                                                                                                                                Lots of love,

                                                                                                                                     Sara
