Scientists study the world and learn about things using a process called the scientific method(方法). By asking important questions and   16  the answers, it is possible to make amazing discoveries! Sometimes a scientist is   17  to answer his own questions, but if he has taken good notes another scientist may come along later who is able to use new knowledge to answer it.
When you use the scientific method to   18  an experiment, you start by making observations(观察) about something that  19  you. Based on your observations, you make a hypothesis. This is using  20  you know to make a smart guess about what you think could happen. Then you are ready to begin your experiment. All   21  your experiment you take down notes, which are   22   experiment date(资料). You are constantly making observations during this time. You may make discoveries that cause you to improve your experiment as you go.   23  , you conclude your experiment and begin to look over your notes to decide what it all means. Based on what you have learned, you make a final statement about   24  your hypothesis was correct or not. You have to have reasons and evidence to support what you are saying.
Using the scientific method can be difficult, but rewarding. Because all the steps are organized in a process, the   25  are more valid(可信的). When you provide observations as evidence to support what you are saying, your ideas are more likely to be accepted.

Gao Wenqi, 49, owner of a restaurant in Xi'an, Shanxi, started to offer a new service on April 13, 2013: suspended meals (待用快餐). Now many restaurants in China, such as in Henan,Chongqing and Yunnan, have joined the program.

    You can pay 10 yuan for a meal, which should be sold at 16, and leave it at the restaurant. Then other people in need, such as the disabled(残疾人), the poor elderly or homeless children,can have it without paying.

    This idea comes from the cafes (咖啡馆) in Naples, Italy. It's a tradition that someone there pays in advance for an extra (额外的) cup or two. Then another coffee-drinker can take them for free.

   “The program is meaningful. It offers help with dignity(尊严),” said Gao to Xinhua. However, people are worried that someone who is able to pay would also ask for the suspended meals, so there should be rules for this program.
