11．　　Sarah is a twelve-year-old girl from London. Now she is on holiday with her family in New York. They are having a very good time.
　　It's Sunday and it's sunny and warm. Now it's ten in the morning and they are in Central Park. Sarah is sitting under a tree. She is listening to her radio and writing a postcard to her friend Joyce.
　　Sarah's father is reading The New York Times, an American newspaper. Her mother is playing with her little brother Jimmy on the grass and they are eating popcorn.
　　Her Canadian cousin Rosemary is also with them. She is drawing flowers. She's very pretty. She's tall and slim and she has got long wavy brown hair. Her parents are in Toronto.
　　There are many people in the park. Some men are running, two girls are walking their dogs, and an old man is skating! And he can do that quite well.
　　Sarah's family often come to this fantastic park because they can relax here. They also visit many other interesting places: museums, shops, galleries etc. They think New York is a wonderful city.

12．　　Vitamins (维他命) help our bodies grow strong and stay healthy. We need vitamins every day and we have to get them from the food we eat. There are two types of vitamins. Some of them live in the fat in our body and stay in our bodies. Others live in the water in our bodies. They don't stay around for long. Which foods do we get our vitamins from? And why do we need them?
　　Let's start with the fat soluble (可溶的) vitamins. A. D and E.
　　Vitamin A: There's lots of vitamin A in carrots and yellow fruits like oranges or mangoes but you can also find some in milk and the yellow part of eggs. Vitamin A helps your eyes and skin stay healthy.
　　Vitamin D: Milk and eggs have also got vitamin D in them and so does fish. When we sit in the sun, our body makes a lot of it naturally. This vitamin is very important for strong bones (骨骼).
　　Vitamin E: On the other hand, it helps keep our blood (血液) healthy. You can get vitamin E when you eat nuts and green vegetables.
　　The water soluble vitamins, B and C are just as important.
　　Vitamin B: There are many different kinds of vitamin B. Some help give us energy (能量) to move our bodies. Others help make blood. We get the different kinds of vitamin B from different kinds of food. These include potatoes, bananas, bread, rice, chicken, fish, cheese, eggs and green peppers.
　　Vitamin C: Vitamin C is good for our bones, teeth and even our brains (大脑). We get this vitamin from oranges, peppers, tomatoes and potatoes. Vitamin C also helps us keep other important substances, such as iron in our body.
　　We should eat a great variety of fruit and vegetables — at least five a day — and lots of other healthy foods like brown bread, milk, eggs and fish. That way, we always get the vitamins we need. And we can also eat some foods that have different vitamins, too. For example, there are three vitamins B in a good bar of dark chocolate!
