Welcome to the world of plants! Are you ready for some amazing facts
Plants are everywhere — on land, in the ocean and even in space! That's cool, right Plants can't speak, but they have surprising power. Let's have a look.
How much did you grow last year Five centimetres Ten centimetres Well, some bamboo can grow 91 centimetres in just one day! That's very fast!
A lot of our food comes from plants. People began to farm and grow their own food over 10,000 years ago.
But plants are more than food. They can also keep us healthy — like “green doctors”. We use different plants to make medicines.
Please look at the plants near you and say hello! They are our great friends.

中药(Traditional Chinese Medicine=TCM) 主要来源于天然药及其加工品，包括植物中药、动物中药、矿物中药等。其中以植物中药居多，故有“诸药以草为本”的说法。例如:
(1) 白芍(debark peony root)
(2) 大枣(Chinese date)
(3) 冬虫夏草(Chinese caterpillar fungus)
(4) 枸杞(wolfberry)
(5) 莲子(lotus seed
(6) 人参(ginseng)
Read and answer.
Rice is a favourite food for many people. We have rice nearly
every day. It’s like a soft and white cloud in our bowls.
Rice means a lot to Chinese culture. There’s a saying, “Every
grain of rice is a drop of farmer’s sweat(汗水).” This means we should cherish（珍惜） our food because it takes a lot of work to grow it. Rice is more than food. It also can be made into different things. Artists use them to show good wishes during festivals and holidays.
For me, rice is not only a gift from the earth, but also something that makes me feel happy.When I eat rice with my family, we share love and have fun together. It is a way of feeling connected（连接） to our roots.
What does rice mean to Chinese culture
