It is said that the eyes are the windows of our soul.Beautiful and bright eyes not only show a good health but also make you look very attractive.However，to have healthy eyes you have to look after them properly.Your eyes need everyday attention.
Pay more attention to your diet.First，eat food that is good for your eyes.They are fresh fruits and vegetables as well as fish，eggs，and milk.Besides，a regular amount of vitamins A and B2 should also be taken.
A regular and sound sleep is a must.It relaxes the eye muscles and gives them the rest required.Sleep not only helps eyes but also helps the body to repair its tired tissues.Usually，you must sleep for at least seven to eight hours every day.Loss of sleep can give you dark circles under the eye.
You must exercise your eyes every day.Blink (刺眼) your eyes at regular periods，which makes the eyeballs watery，and gives them a good wash.
We use our eyes in many unnoticeable and wrong ways.For example，if a small thing goes into our eye we start rubbing (揉) it，which is wrong.Rubbing can cause damage to your eyes.Don't read or write in poor or bright sunlight.Always use sunglasses as sunlight can cause eye tiredness.Light should not shine directly in your eyes.Too much reading，writing，watching television or working on the computer can also cause eye tiredness.
Remember to always take care of God's most beautiful gift to you.Your life will be very colorless without your eyes.

Teamwork is just as important in science as it is on the playing field or in the gym.Scientific investigations (调查) are almost always carried out by teams of people working together.Ideas are shared，experiences are designed，data are analyzed，and results are evaluated and shared with other investigators.Group work is necessary，and is usually more productive than working alone.
Several times throughout the year you may be asked to work with one or more of your classmates.Whatever the task your group is assigned，a few rules need to be followed to ensure a productive and successful experience.
What comes first is to keep an open mind，because everyone's ideas deserve consideration and each group member can make his or her own contribution.Secondly，it makes a job easier to divide the group task among all group members.Choose a role on the team that is best suited to your particular strengths.Thirdly，always work together，take turns，and encourage each other by listening，clarifying，and trusting one another.Mutual support and trust often make a great difference.
Activities like investigations are most effective when done by small groups.Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her，and everyone knows exactly when，why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning，though it is by no means unwise to compare your observations with those of other group members.
When there is research to be done，divide the topic into several areas，and this can explore the issue in a very detailed way.You are encouraged to keep records of the sources used each person，which helps you trace back to the origin of the problems that may happen unexpectedly.A format for exchanging information (e.g.photocopies of notes，oral discussion，etc.) is also important，for a well－chosen method not only strengthens what you present but also makes yourself easily understood.When the time comes to make a decision and take a position on an issue，allow for the contributions of each member of the group.Most important of all，it is always wise to make decisions by compromise and agreement.
After you've completed a task with your team，make an evaluation of the team's effectiveness—the strengths and weaknesses，opportunities and challenges.

Communication Principles
How you see yourself can make a great difference in how you communicate.“Every individual exists in a continually changing world of experience of which he(or she)is the center”．Many communication scholars and social scientists believe that people are products of how others treat them and of the messages others send them.But every day we experience the centrality of our selves in communication.A student，for instance，may describe a conflict with a teacher as unfair treatment：“I know my teacher doesn't like the fact that I don't agree with his opinions.and that's why he gave me such a poor grade in that class.”The teacher might say the opposite.Each person may believe that he is correct and that the other person's view is wrong.
The concept of serf originates in communication.Through verbal and nonverbal symbols，a child learns to accept roles in response to the expectations of others.You establish self－image。The sort of person you believe you are，by how others think of you.Positive，negative，and neutral messages that you receive from others all play a role in determining who you are.Communication itself is probably best understood as a dialogue process.Our understanding of communication comes from our interactions with other people.In a more obvious munication involves others in the sense that a competent communicator considers what the other person needs and expects when selecting messages to share.So，the communication begins with the self，as defined largely by others，and involves others，as defined largely by the self.
Communication Occurs almost every minute of your life.If you are not communicating with yourself(thinking，planning，reacting to the world around you)，you are observing others and drawing inferences from their behavior.Even if the other person did not intend a message for you.you gather observations and draw specific conclusions.A person yawns and you believe that person is bored with your message.A second person looks away from you and you conclude that person is not listening to you.A third person smiles(perhaps because of a memory of a joke he heard recently) and you believe that he is attracted to you.We are continually picking up meanings from others' behaviors and we are constantly providing behaviors that have communicative value for them.
More often than not，you may have hurt someone accidentally and you may have tried to explain that you did not mean that.You may have told the other person that you were sorry for your statement.You may have made a joke out of your rude statement.Nonetheless，your comment remains both in the mind of the other person and in your own mind.You cannot go back in time and erase your messages to others.Communication cannot be reversed(倒退)，nor can it be repeated.When you tried to re—create the atmosphere，the conversation，and the setting，nothing seemed right.Your second experience with a similar setting and person made far different results.

The rate of population growth is fastest in underdeveloped countries.In these countries a high birthrate is accompanied by a lowered death rate thanks to improved standards of public health.Ideally it should be possible to counter(相反地) balance the effect of a reduced death rate by an increased use of family planning.In practice，however，population control is a complex matter.Throughout history people have determined the size of their families according to the cultural values of their societies.
Population control has long been a subject of discussion among researchers.Some have argued that the supply of good land is limited.In order to feed a large population，bad land must be cultivated and the good land overworked.As a result，each person produces less in a given amount of time and this means a lower average income than could be obtained with a smaller population.Other researchers have argued that a large population gives more range for the development of facilities such as sports，roads and railways，which are not likely to be built unless there is a big demand for them.Similarly，it can be argued that the public costs of society will not be so heavy to each individual if they are shared among the members of a large population.
One of the difficulties in putting birth control into practice lies in the fact that official attitudes to population growth vary from country to country.In underdeveloped countries where a large population is pressing hard upon the limits of food，space and natural resources，it will be the first concern of government to place a limit on the birthrate.In a well developed society the problem may be more complex.A declining birthrate may lead to unemployment because it results in a decreasing market.Cities with a declining population may have to face the prospect of a decreasing tax base and a fall in land values.If there are fewer children going to school，teachers may be thrown out of work.When the pressure of population on housing declines，prices also decline and the building industry is weakened.Faced with considerations such as these，the government of a developed country may well prefer to see a slowly increasing population，rather than one that is stable or in decline.

Preschools are usually regarded as a fun learning experience where children can pick up their basic learning skills，which help them to be better，prepared for the legal education ahead.A preschool is also known as kindergarten or nursery school，which provides basic learning skills for children between the ages of two to five.
Preschools focus on getting the children to communicate better with other children as well as adults around them.Preschool－education also focuses on encouraging children's creativity and encouraging them to express their thoughts and ideas through speaking and drawing as well.Preschools also usually include simple exercises and outdoor games to make sure of the physical fitness of the children.Preschools also help develop children's basic mathematical skills.In a word，the goals of preschool－education can be summarized (总结) as one point—to develop a child's overall growth.
To make the education both creative and fun，preschools can organize many preschool games and activities.For example，educational visits to the zoo or other places are an excellent way for children to learn about different types of animals and other extracurricular (课外的) knowledge.Making children exposed to educational computer games in proper levels can be a great way to improve the children's hand－eye coordination (协调) and introduce the children to the technology.What's more，drawing can also help in developing the children's aesthetic (审美) sense，and it is also a creative way of expression for the preschoolers.
