88-year-old Gao Siji lives in Hangzhou, Zhejiang Province. She often goes to seafood stores to1fish bones. In her eyes, they are not2, but great things for making works of art. And she is3for her fish-bone pictures. Lots of people love them.

You may wonder4Gao started making pictures with fish bones. It was about 30 years ago." As soon as I left my job because of age, I went to study 5When I ate fish one day, I got interested in the6of the fish bones and had a(n)7to make works of art with them," she said."Then I cleaned the fish bones, colored them and glued them together to finish my first fish-bone picture." The picture was wonderful and Gao fell in love with this kind of art. Soon she started using other seafood waste to make pictures. Over the past thirty years, Gao has made more than one hundred works of art. How8she is !

Gao's fish-bone pictures are a good example to make us believe that there is no such thing as waste, only resources (资源)in the wrong place.9 should make full use of waste. Gao also10people in need, she gave the money she won from competitions to special education groups.

Animals do many different, amazing things to get through the winter. Some of them migrate. They travel to other places where the weather is warmer or where they can find food.

Many birds migrate in autumn. Because the trip can be dangerous, some travel in large groups. For example, geese(鹅) fly in noisy, "V-shaped groups. Other kinds of birds fly alone.

Some animals stay active in winter. They must change themselves as the weather changes. Many change their doing or their bodies. For example, snowshoe rabbits grow white fur to help them hide in the snow.

Food is hard to find in winter. Some animals, like mice, collect lots of food in autumn and store it to eat later. Some animals eat different kinds of food as the seasons change.

Some animals hibernate(冬眠) for part or all of the winter. This is a special, very deep sleep. The animal's body temperature drops, and its heartbeat and breathing slow down. It uses very little energy. In autumn, these animals get ready for winter by eating much more food than in summer and storing it as body fat. They use this fat to keep them alive while hibernating.

Water makes good protection for many animals. When the weather gets cold, they move to the bottom of lakes and rivers. There, frogs and many fish hide under rocks or fallen leaves. Cold water holds more oxygen than warm water, and frogs can breathe through their skin.

Every type of insect( 昆虫) has its own life cycle and that is the way it grows and changes. Different insects spend the winter in different forms of their lives. Some insects also spend the winter without moving. Some insects spend the winter as pupae(蛹). Other insects die after laying eggs in autumn. The eggs change into new insects in spring and everything begins all over again.

About three months ago, I took my nine-year-old son to Qingdao, Shandong, It was a special trip.

When we got there, my son was very (excite) because it was the first time for him (take) the subway.

When we got on the subway, I found It was (fill)of people and we had to stand. However, a boy wearing sports clothes asked me to sit in his seat. He also advised his friend siting next him to do that. So it would be easy for me to take care of my son.

I said "Thank you" as he (stand) up and then we sat down. When we got the subway, the kind boy (say)goodbye to us.

Later I lost my wallet while I was (shop)in the city center. (luck) a stranger found it and r it to me.

These kind people really made our trip to Qingdao very unforgettable. I told my son that we should try our best to help the people in need in return.
