Be Brave With New Things

   The old advertising slogan, “so simple a child can do it ,” has taken on new meaning to me. A few weeks ago I got a computer, but I an mechanically illiterate. I knew that children had no fear of the future, so that seemed a good place to seek help. I asked my nephew, twelve years old, at an elementary school, to help me.

   My nephew took the machine for granted and has simply accepted the fact that computers are now a way of life. He plays with them and does his homework on them and even creates programs for them. I , on the other hand, are terrified by what this equipment can do. It can interchange paragraphs, switch words around and even correct my spelling. It informs me of Its limitations, takes commands and asks questions. It even seems to have a sense of communication. Rather than accusing me of making an error, it prints “One of us has made a mistake!” It never gets tired and is always patient and ready to go when I am.

   I think it was somewhat normal for me to be suspicious of computers. They represent a break with some very familiar habits and traditions. It is only human to instinctively avoid anything that shifts thoroughly from the acceptable, comfortable past. But the world is governed by ceaseless change and we must therefore establish links with the present and future as well as the past. Computer technology is an excellent case in point, as the newest systems grow out of date in only a few years, or even months.

   This ability to see, experience and accept the new is one of our saving characteristics. To be fearful of tomorrow, to close ourselves to possibilities, to resist the inevitable, to advocate standing still when all else is moving forward, is to lose touch. If we accept the new with joy and wonder, we can move gracefully into each tomorrow. More often than not, the children shall lead us.

Psychologists tell us that there are four basic stages that human beings pass through when they enter and live in a new culture.This process begins with the “honeymoon stage”.This is the period of time when we first arrive in which everything about the new culture is strange and exciting.We may be suffering from “jet lag” but we are thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kinds of food.This stage can last for quite a long time because we feel we are involved in some kind of great adventure.
Unfortunately, the second stage can be more difficult.After we have settled down into our new life, we can become very tired and begin to miss our homeland and our family, friends, pets.All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture.This period of cultural adjustment can be very difficult and lead to rejecting or pulling away from the new culture.
The third stage is called the “adjustment stage”.This is when you begin to realize that things are not so bad in the host culture.Your sense of humour usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place.Things are still difficult, but you are now a survivor!
The fourth stage can be called “at ease at last”.Now you feel quite comfortable in your new surroundings.You can cope(deal) with most problems that occur.You may still have problems with the language, but you know you are strong enough to deal with them.

Believe it or not, oceans and seas are easy to be harmed by the development of human society. They are also influenced by man-made pollution easily. It is human beings that do great harm to the ocean ecosystems(生态系统).

The coral reefs(珊瑚礁)are fine ecosystems that provide food and protection for many ocean creatures. The coral in almost all of the oceans is in danger from pollution.Chemicals from factories end up in the seas and oceans and destroy coral reefs. If the coral systems die some ocean creatures will be sure to die out.

Protecting the ocean also has something to do with the protection of ocean wildlife like dolphins. The fishing industry depends on modern ways to catch many fish in order to earn more money. But the nets for fishing also seize other sea animals. The fishing boat workers are advised to check their nets and set other ocean animals free. But the boats are in a hurry to make money and often other ocean animals are caught with fish.

Offshore oil spills(近海石油泄露) can destroy the ocean environment because oil kills all ocean life. The world depends on oil and because there is a great amount of oil off the shore of many countries, the need for oil is more important than the risk of the oil spill. However, the fact is that one human mistake can lead to an ocean environmental accident that will cause years of damage to the fine ocean ecosystems. Oil spills will kill all the creatures in the area of the spill. The oil will be washed up on shore and destroy the ecosystems along the shore including birds.

Everyone who cares about the environment should be interested in protecting the ocean, and all of us should do something for the protection of the ocean.
