1 . A jigsaw is a power-driven saw (锯) used to cut sharp curves (急弯曲线) in pieces of wood.
A jigsaw is also a puzzle. It is made up of a large number of small, interlocking pieces. Each piece has a small part of a picture on it. A completed puzzle produces a picture or design.
Jigsaw puzzles were first created by producing a picture on a flat, rectangular (矩形) piece of wood, then cutting that picture into small pieces with a jigsaw – that’s where the name comes from!
Pictures found on jigsaw puzzles mainly include scenes from nature, city life and similar designs. Castles, mountains and water scenes are traditional subjects. However, any kind of picture can be used to make a jigsaw puzzle. Cartoon-styles are popular. There are companies that create puzzles from personal photographs. Completed puzzles can also be glued onto a piece of wood to make a wall hanging.
The first jigsaw puzzles were designed as geography teaching tools by John Spilsbury in 1767. His “jigsaw” was a map puzzle. It was a hand-painted map of England on a piece of wood. It was a successful teaching method. He went on to make over thirty other map puzzles. The pieces were not interlocking.
With the invention of power tools more than a century later, jigsaw puzzles with fully interlocking pieces came into being. The jigsaw machine could cut sharp curves. Then the name jigsaw puzzles came into being. Jigsaw puzzles became very popular in the United States in the early 1930s, when people had difficulty in finding jobs and making money.
Today puzzles of all sizes are a standard item in toy shops and supermarkets. However, they usually come in 300-piece, 500-piece, 750-piece, and 1,000-piece sizes. The largest one even has 24,000 pieces.
Some jigsaws are quite tricky. Try doing one with all pieces without pictures on it. A few puzzles are made double-sided, so they can be solved from either side. This increases the difficulty, because the puzzle solver cannot be certain which way up each piece goes. Some jigsaws do not have straight edges (边缘). The edge pieces could be any interlocking piece. Solving these jigsaws requires more effort than doing those straight-edged ones. Others designedly have a piece or two missing. Jigsaws are no longer educational toys but are used for entertainment or a hobby.

Do you live in a city? Do you know how cities began? Long long ago, there were only a few thousand people in the world. These people moved from place to place. They moved over the land, hunting(打猎)animals for food.
A long time passed. These people began growing crops. No one knows how or when those people learned about growing food. But when they did, their lives changed, they did not have to move houses any more.
They could stay in one place and grow it. People began to live near each other. And so the first villages grew. Many people came to work in the villages. These villages grew bigger and bigger. Then people had machines, and lives in the villages changed again. They built factories. So the villages grew into cities. Some of them grew very big.
Today, some people are moving back to small towns.

4. Why did people move from place to place long long ago?

People usually like to mark their space. Are you sitting on a beach or a train or in a library? If you are on the beach you may have spread your sands around you; on the train you may have put your coat or a small bag on the seat beside you; in a library you may have one corner or chair which is your own.
Once I was traveling on a train to London. I was in a section for four people and there was a table between us. The man sitting opposite me had his bag on the table. There was no space on my side of the table at all. I was made rather angry. Maybe he thought that he owned the whole table! I took some newspapers out of my bag and put them on his. When I did this he sat up straight at once, opening his eyes wide. I had invaded(侵占)his space! A few minutes later, I took my newspapers off his bag in order to read them. He at once moved his bag to his side of the table.
