Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇) levels.
Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died.
The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first.

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.

Dear editor（编辑）
I live in a beautiful city. Many visitors come to my city. There are so many colorful peacocks(孔雀)here .The peacocks mostly live on the grass land of Dongfeng Square（广场）
They are given food freely by visitors ,They usually throw food to them ,and don’t think about at all whether the food is right or not. Some of the peacocks became ill, some even died after eating the bad food given by the visitors . I’m sure most of the visitors who throw food to the peacocks really like the birds ,but don’t realize(意识到)that they may be doing them harm (伤害).The visitors should be told that what have done is very harmful to the birds , and this kind of thing must be stopped from happening Perhaps we can build some small shops beside Dongfeng Square to sell peacock food .For us every person, it’s our duty to give more love to these beautiful birds and to look after them carefully.
Yours,
Sun Yan

Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took days, weeks and sometimes months for people to receive news. Now it is possible to send words and pictures around the world in seconds. Billions of people learn about news of their country and all over the world every day, either by watching TV or reading newspapers.
Newspapers have been an important part of everyday life since 18th century. Many countries have hundreds of different newspapers. How do newspaper editors decide which news to print？ Why do they print some stories and not others? What makes a good newspaper story?
Firstly, it’s important to report news. TV stations can report news much faster than newspapers. Yet, newspapers give more about the story. They may also look at the story in another way, or they may print completely different stories from those on TV.
Secondly, a new story has to be interesting and unusual. People don’t want to read stories of everyday life. As a result, many stories are about some kind of danger and seem to be “bad” news. For example, newspapers never print stories about planes landing safely, instead they print stories about plane accidents.
Another factor(因素) is also very important. Many people are interested in news in foreign countries, but more prefer to read stories about people, places and events in their own country. So the stories on the front page in Chinese newspapers are usually very different from the ones in British, French and American newspapers.
