Millions of people around the world cook their food on fire every day. People must spend lots of money on cooking fuel. However, there is a much easier and cheaper way to cook food using energy from the sun.
Sun-cookers have been used for centuries. A Swiss scientist made the first sun-cooker in 1777. Today, people are using sun-cookers in many countries around the world. People use them to cook food and to heat drinking water.
There are three kinds of sun-cookers. The first is a box cooker. It is designed with a special wall that collects sun-shine into the box. A box cooker is good for slow cooking of a lot of food.
The second kind of sun-cooker is a panel cooker. It has several flat walls that concentrate the sun-shine on the food. People can build panel cookers quickly. They do not cost much. In Kenya, for example, panel cookers cost just two dollars.
The third kind of sun-cooker is a parabolic cooker. It has rounded walls that concentrate sunlight into the bottom of the cooker. Food cooks quickly in parabolic cookers. However, these cookers are hard to make. They must be moved again and again to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make sun-cookers from boxes or heavy paper. They will not catch fire. Paper burns at 232℃. A sun-cooker never gets hotter than that. Sun-cookers cook food at low temperatures over long periods of time. This allows people to cook food and do other things at the same time.

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.
In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙細胞﹚to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word ”means, we can help to save people from several illness. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的)，or stop sick people getting jobs.

500 years ago in Britain, the burning of coal (煤) was increasing in cities like London. Coal was used in factories and also used to heat homes. Coal, when burnt makes a lot of smoke, which makes the air very dirty.
About 200 years ago, the Industrial Revolution (工業(yè)革命) began in Britain. Factories were built, and even more coal was burnt. Air pollution was becoming a really big problem.
Smoke and fog together make smog (煙霧). Smog was a big problem in London's winter. Because of the cold weather, more coal was burnt to warm houses and this made more smoke.
When smog stayed over a city, it became really hard to breathe and see clearly. In 1952, the Great London Smog happened and more than 4,000 people died because of the smog.
New laws (法律) were made in 1956 and 1968 to stop such sad things from happening again. These laws were called the Clean Air Acts.
These laws were made so that air would become cleaner. The laws encouraged people to use less coal or switch to other fuels such as gas. Factories started using tall chimneys (煙囪) so that the smoke would go high up in the sky and no longer cover cities, and new factories were built in the countryside. Smog appeared less often and the air became cleaner.
小題1:From the passage, we learn that smog was a big problem in ______ in London.
A．springB．summerC．a(chǎn)utumnD．winter
小題2:The underlined words "switch to" mean "______"  in Chinese.

According to a new Ministry of Education (教育部) survey, student safety has become a big problem. Nearly 50 percent of students say they are worried about robbery on the way to and from school. Now in many big cities in China, some school has taught an unusual lesson: self– protection. Students like this lesson as there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School and a self–protection expert, gives young students advice on how to deal with danger.
If you are robbed
Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police.
If you are in a traffic accident

Don’t stay in high places and keep away from trees.
When there is a fire
Get away as fast as you can. Put wet things on your body and try and find an exit. Do not take the lift!

The rapid growth of Smartphones and electronic tablets（平板電腦）is making the Internet favourite for Americans reading news, a report said.
News consumption online increased 17% last year from the year before. Television news, newspapers, radio and magazines all lost audience last year. For the first time, the number of people who get news online at least three times a week is larger than the number of people who get news from the newspapers. TV news has been the most popular since the 1960s. It has replaced the afternoon newspapers. But now the online news seems to be more popular than the TV news.
People are used to having the Internet available on phones or small tablets. In December, 2010, 41% of Americans said they got most of their news on the Internet, more than double the 17% who said that a year earlier, the report said. In January, 2011, 7% of Americans owned electronic tablets, nearly double what it was three months earlier. It was the fastest-growing new digital technology, ahead of mobile phones when they were introduced. The online ad income was expected to surpass（超過）print newspaper ad income for the first time in 2010.
The news business used to be the intermediary（中介）. You needed newspapers and TV stations to reach your customers. In this age of the computer, it’s the software developers that you need.
小題1:Americans like getting news from ________ best today.
A．TV news
B．the Internet
