Learning science can bring a double benefit because science is both a method and a set of ideas, both a process and product. The processes of science provide a way of finding out information, testing ideas and see- king explanations. The products of science are ideas which can be applied in helping to understand new experiences. The word "can" is used advisedly here, it indicates that there is the potential to bring these benefits but no guarantee that they will be realized without taking the appropriate steps. In learning science the development of the process side and the product side must go hand in hand, they are totally interdependent. This has important implications for the kinds of activities children need to encounter in their education But before pursuing these implications, there are still two further important points which underline the value of including science in primary education.
The first is that whether we teach children science or not, they will ha developing ideas about the world around from their earliest years. If these ideas are based on casual observation, non-investigated events and the acceptance of hearsay, than they are likely to be non-scientific. "everyday" ideas. There are plenty of such ideas around for children to pick up. My mother believed (and perhaps still does despite my efforts) that if the sun shines through the window on to the fire it puts the fire out, that cheese maggots f a common encounter in her youth when food was sold unwrapped) are made of cheese and develop spontaneously from it, that placing a lid on a pan of boiling water makes it boil at a lower temperature, that electricity travels more easily if the wires are not twisted. Similar myths still abound and no doubt influence children's attempts to make sense of their experience. As well as hearsay, left to themselves, children will also form. some ideas which seem unscientific; for example, that to make something move requires a force but to stop it needs no force. All these ideas could easily be put to the test; children's science education should make children want to do it. Then they not only have the chance to modify their ideas, but they learn to be sceptical about so-called "truths" until these have been put to the test. Eventually they will realize that all ideas are working hypotheses which can never be proved right, but are useful as long as they fit the evidence of experience and experiment.
The importance of beginning this learning early in children's education is twofold. On the one hand the children begin to realize that useful ideas must fit the evidence; on the other hand they are less likely to form. and to accept everyday ideas which can be shown to be in direct conflict with evidence and scientific concepts. There are research findings to show that the longer the non-scientific ideas have been held, the more difficult they are to change. Many children come to secondary science, not merely lacking the scientific ideas they need, but possessing alternative ideas which are a barrier to understanding their science lessons.
The second point about starting to learn science, and to learn scientifically, at the primary level is connect- ed with attitudes to the subject. There is evidence that attitudes to science seem t

Introductions
Every day we encounter people in a variety of business and social situations. The way we meet and greet them creates lasting impressions and paves the way for a productive encounter, Introductions project information. Besides the obvious elements of name. title, and affiliation (关系), an introduction conveys a level of respect and reflects how the person making the introduction views the other person's status. Mastering the art of the introduction will help put you and the people you are introducing at ease. Learning the basics--and they are not very difficult --is the first step.
The most important point about introductions is to make them. Failing to do so causes embarrassment and discomfort. A second important point in any introduction is the order of names. The name of the person being introduced is mentioned last. and the person to whom the introduction is made is mentioned first. The rules for who is introduced to whom depends on whether it's a business or a social introduction.
Business Introductions
In business, introductions are based on power and hierarchy (等级). Simply, persons of lesser authority are introduced to persons of greater authority. Gender plays no role in business etiquette (礼节): nor does it affect the order of introductions. For example, you would say, "Mr. / Ms, Greater Authority. I would like to introduce Mr./Ms. Lesser Authority."
Social Introductions
Social etiquette is based on chivalry(骑士精神), so both formal and informal introductions are made according to age, then gender, and then social status. The man would be introduced to the woman in a social situation unless the man is obviously a great deal older, in which case one would defer(听从，服从) to age over gender.
As you make the introduction, include a brief but meaningful piece of information about each of the people to explain their uniqueness or importance. But never qualify a description by saying "my best client" or "my dearest friend" because the automatic implication is that the other person holds a lower position in your personal hierarchy. When in doubt, be less personal rather than more personal.
The Nuances (细微差别)
As you say each of the individuals' names, look at him or her. In this way, you focus attention on them and make them feel important. Once a conversation has begun and everyone seems at ease, you may excuse yourself.
When introducing peers to one another, mention both the first and last names. It doesn't matter who is introduced to whom. Including a little bit of information that might start the conversational ball rolling is always a good idea. Even if everyone in a group is on a first name basis, introduce people by both first and last names.
Introducing Yourself
If no one introduces you, step in and introduce yourself. Someone may be too embarrassed to admit forgetting a name or may be distracted by other matters. Feeling slighted because you were not introduced only puts you at a disadvantage. Introduce yourself by extending your hand, smiling and saying something like, "I'm Matt Jones, David's partner." Avoid making any comment such as "Helen works for me" that might be considered as arrogance or superiority. Instead, say, "Helen and I work in the same office."
As a guest, it's your duty to circulate and introduce yourself at any function, large or small, especially if the host or hostess is busy. The fact that you are both there is sufficient justification to introduce yourself to anyone at the gathering. By only sticking to those people you already know, you'll never expand your horizons or make new acquaintances.
Always use both names when introducing yourself to convey the message that you take yourself seriously as an adult and expect the same treatment from others. And, since you don't know how comf
