The word science is heard so often in modern times that almost everybody has an idea of its meaning. However, its definition is difficult for many people. The meaning of the term is confusing, but everyone should understand its meaning and objectives (目标). Just to make the explanation as simple as possible, suppose science is defined as classified knowledge or facts.
Even in the true science, distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses(假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion.
The objectives of science are primarily the discovery and later the understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature of that questions are unanswerable; he must solve them. Toward that end, specialists in the field of biology and related fields of interest are directing much of their time and energy.
Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. However, one should remember that the construction of the microscope had to come before the discovery of the cell. The host of scientists devoting their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied.
The other is aimed at using knowledge for specific purposes--for instance, improving health, raising standards of living, or creating new consumer products. In this case, knowledge is put to economic use. Such an approach is referred to as applied science.

When the musical sound rings you, you immediately reach for your pocket ready to have a chat.But although you probably use it all the time, have you ever stopped to think about the manners related to talking on the phone? If you haven’t, here are some tips to guide you.
●Always give the person you are calling plenty of time to get to the phone before you hang up.If the person who answers is not the one you want,give your name and ask if you may speak to the person you want.
●Think about the time you call people.Try not to call too early in the morning(before about 9:00)or too late at night(after about 9:30).Also try not to call at mealtimes.
●If you go by plane to visit your relatives at Christmas, remember to follow airline instructions.Cell phones must be turned off as soon as the plane doors are closed and remain so until the doors open again on arrival.
●When face to face with someone, do not talk on the phone.It is rude to be on the phone when a waiter is trying to take your order in a restaurant, or when you are returning the shoes you have just been trying on in a shop.Finish any face-to-face business before taking a call.Continuing to use the phone while nodding to the person in front of you is quite impolite.
●When in a restaurant with your friends,keep phone conversations short.Make a call only if it is important.Practise speaking in a low voice.If no one looks your way, you’ve got it.
●If you go to a theatre, a concert or a cinema, consider the other people around you.Check that your phone is “off” before you enter.If you are expecting a very important call, put your phone on “vibrate”(振动)and run for the exit as soon as you feel it.If you forget both “off” and “vibrate” and your phone rings, don’t answer it, turn it off straight away.

查看习题详情和答案>>To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't.
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council.“The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants(参与者)scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake.
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years.
“We can't say that any person could gain 14 years by doing these things, ”said Dr.Tim Armstrong, a physical activity expert at the World Health Organization.“The 14 years is an average across the population of what's theoretically(理论上地)possible.”
“Most people know that things like a good diet matter and that smoking isn't good for them, ” Susan Jebb said.“We need to work on providing people with much more practical support to help them change.”
