Today, roller skating is easy and fun. But many years ago, it wasn’t easy at all. Before 1750, people never tried skating on wheels. That changed because of a man named Joseph Merlin. Merlin’s work was making instruments. In his free time he liked to play the violin. Merlin was a man with many ideas and many dreams. People called him a dreamer.
One day Merlin received an invitation to go to an important party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think. He wanted to find a way to make a wonderful entrance at the party. Merlin had an idea. He thought that he would attract a lot of attention if he could skate into the room.
Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skate shoes. Merlin was very proud of them. He dreamed of arriving at the party and skating into the room while playing the violin. He was sure that everyone would be very surprised.
On the night of the party Merlin rolled into the room, playing his violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop his roller skating. He rolled on, playing the violin. Then, with all eyes on him, Merlin hit into a huge mirror on the wall. The mirror broke into many pieces with a very loud noise.

In the 19th century England people liked to go to the seaside. In those days, ladies wore long bathing dresses, and men wore bathing suits. Women did not walk about on the beach in their bathing dresses. They hired a bathing machine. A bathing machine was used for changing in, and for taking the bather down to the sea. It cost 2 pence to hire a machine and an attendant (f~ ~). When she had paid, the bather climbed up the back steps and got into the bathing machine. Then she changed into her bathing dress. When she had changed , the machine was pulled down to the sea. The bathing machine stopped in the water and the bather went down the front steps into the water.

Annealing
Annealing is a way of making metal softer by heating it and then letting it cool very slowly, if metal is heated and then cooled very quickly, for example by dipping(浸) it in water, it will be very hard but also very brittle(脆)—that is, it will break easily. Metal that has been annealed is soft but does not breaks as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other material, such as glass.
1. Annealing can make metal ____
A. hard and tough(韧) B. hard but brittle C. soft but tough D. soft and brittle
2. Why do people put hot metal in water?
A. To make it hard. B. To make it soft. C. To make it cool. D. To make it brittle
3. In annealing, the required hardness of a metal depends on ______
A. the quantity of water used B. the temperature of the metal
C. the softness of the metal D. the timing of the operation
4. As suggested by the text, how can glass be made less brittle?
A. It can be heated and then cooled quickly.
B. It can be cooled and then heated slowly.
C. It can be heated and then cooled slowly.
D. It can be cooled and then heated quickly.
When several different people look at the same person, it is not unusual for each of them to see different things; when you alone observe one behavior or one person at two different times, you may see different things. The following are but some of the factors that lead to these varying perceptions（感知，感觉）: 
Each person's perceptions of others are formed by his or her own cultural conditioning, education, and personal experience.
Sometimes perceptions differ because of what we choose to observe and how we deal with what we've observed. It is not necessarily true that person's perception is based on observations of a particular person. Your observations may be totally controlled by some. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same yardstick（尺码） to measure their parents, their friends, and strangers.
Sometimes we see only what we want to see what may be obverse（正面的）to others because of our own needs, desires, or temporary（临时的） emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory（相反的） information is particularly obvious, but it can be done. We can ignore the stimulus（刺激）-"He's basically a good boy, so what I saw was not shoplifting（入店行窃）." We can reduce the importance of the contradictory information -"All kids get into mischief（顽皮）. Taking a book from the bookstore isn't such a big deal." We call change the meaning of the contradictory information-"It wasn't shoplifting because he was going to pay for it later."...

Shishmaref, an Eskimo village on an island off northwestern Alaska, is falling into the ocean. Giant storm waves have so hit the place-once well bufferedby sea ice-that villagers voted in 2002 to leave their ancestral home for the mainland. They are being called one of the first refugees（难民）of global warming. k+s-5#u 
"We tend to describe climate change in terms that are abstract-a one degree rise in temperature, an increase in greenhouse gases-but when waves wash away a village, that's concrete and very emotional," says Igor Krupnik, an expert at the National Museum of Natural History. "When they lose a piece of their land, they aren't just losing a certain number of square miles. They are losing part of their history and their memory. They are losing childhood events and grandparents' tales."
Before temperatures began to rise in Shishmaref about 30 years ago, 20 to 30 miles of hard sea ice protected the village from powerful fall storms. But the natives say the ice doesn't freeze as solidly or as soon as it used to and now stretches only six or seven miles, leaving the community of 600 people more exposed. Storms have swept houses into the ocean.
The villagers' plan is to move to Tin Creek, a site on the Alaska mainland 12 miles away, and they have received $180 million from the government. Residents hope that in their new community they'll be able to maintain their close ties, continue hunting animals, and keep fishing, much as their ancestors have done for centuries. "People are asking why the government should be spending so much money on so few people," said a government official. "But people in Alaska are like everyone else. We want to help keep their culture alive."
