Millions of people around the world cook their food over smoky fire every day.It is often difficult to find wood for the fire .People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.
Solar cooker, or ovens,have been used for centuries.A Swiss scientist made the first solar oven in seventeen sixty-seven. Today ,people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.
There are three kinds of solar ovens.The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amonts of food.
The second kind of solar oven is a panel cooker. It includes several flat walls.or panels.that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much.In Kenya ,for example ,panel cookers are being manufactured for just two dollars.
The third kind of solar oven is a parabolic cooker.It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make.They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

dancer.It’s a goal for millions and millions of families every year——keep the Christmas spending within a certain amount, but can still afford the gifts that your loved ones will enjoy. Never has this concern been greater in recent years than right now. Even so, there are several things that you can do to help.
Hit the sales.
No one wants to get up at four o’clock in the morning and fight to get the best deal on Black Friday, and it’s surely very tough to pick up the courage and get out there in the cold for a good deal, but sometimes——it can be well worth. Many retailers(零售商) offer specials all through the day——and some even offer online Black Friday specials, so you may still be able to get a great deal on Black Friday.
Pay close attention to advertisements.
Once the Christmas shopping season is coming, retailers hungry for business will do just about whatever to get you in the store. Pay very close attention to weekly advertisements of sales among the major retailers and you may be lucky enough to find different prices for the same thing in different shops.
Shop online.
Some of us don’t like running from store to store in order to get the best price on the perfect gift, and some of us don’t like to go out in the cold at all——thankfully for us, we can do online shopping.
The world of online shopping lets people visit all the major retailers as well as some specialty stores that could only be found on the Internet. Customers can find exactly what they are looking for, at the best possible price without ever having to leave the house. With traditional Christmas shopping consumers are sometimes limited to what’s left in stock if they wait too long to get to a particular store.

Usually, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is “What’s your name?” Everyone gives a different answer, but everyone is correct.
Have you ever wondered about people’s names? Where do they come from? What do they mean?
People’s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.
Some people give their children names that mean good things. Clara means “bright”; Beatrice means “one who gives happiness”; Donald means “world ruler”; Leonard means “as brave as a lion”.
The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪)；someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.
Other early surnames came from people’s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter — a person who owned or drove a cart; Potter —a person who made pots and pans.
The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter’s great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father’s name. English-speaking people added –s or –son. The Johnsons are descendants of John; the Roberts family’s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnells and the McDonnells and the O’Donnells are descendants of the same Donnell.
