Most people who move to a foreign country may experience a period of time when they have a lot of stress in the new culture. This feeling is often called “culture shock” and it is important to learn how to deal with culture shock. First of all, you should know that everyone in a new situation will go through some form of culture shock. There are four general stages of cultural adjustment(适应).

    The first stage is usually referred to as the honeymoon stage. Upon arriving in a new environment, you'll be interested in the new culture. Everything will seem exciting, and everyone will seem friendly and helpful.

    The second stage is called the withdrawal stage. The excitement that you felt before changes to frustration(沮丧) as you find it difficult to deal with new problems. The language is hard to learn; friends are hard to make; simple things like shopping and going to the bank are challenges. It is at this stage that you are likely to feel anxious and homesick.

If you are one of those who manage to stick it out (坚持下来), you will enter the third stage—- the recovery stage. At this point, you'll feel more confident in the new culture. You'll start to understand and accept the way things are done and the way people behave in your new environment.

The last stage is the stability stage—- this is the point when people start to feel at home in the new culture. At this stage, you will behave well in the new culture, and prefer some aspects(方面) of the new culture to your own culture.

    There is, in a sense, a fifth stage to this process. If you decide to return home after a long period in a new culture, you may experience what is called “reverse culture shock”. This means that you may find aspects of your own culture “foreign”, because you're so used to the new culture. Reverse culture shock is usually pretty mild(温和的) and doesn't last for very long.

It's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends—every moment in their life would be like seeing the world for the first time.

    But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago.

    In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.

Researchers used computer software to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

    In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

    Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild.

    “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

    For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

    For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

    Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents “point of view, the only cause of their fight is their adolescents” complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

    In this article, I'll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen's hair, the cleanliness of the bedroom, the preferred style of clothing, the child's failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn't matter what the topic is - politics, the laws of physics, or the proper way to break an egg - the point of these arguments is to prove that you are right and other person is wrong, for both wish to be considered an authority - someone who actually knows something - and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they'll continue to fight these battles forever and never make any real progress.

    When my son was about five or six, I traveled a lot on business. I worried all the time about what the absence might mean to him. I knew how important it was for a boy to have his father near. When I was small, the times I loved most were the special moments I shared with my father. I cherished these special moments and, to this day, hold those memories dear. I decided to create those kinds of special times for my son.

    In one of my letters home, I promised my son that I would teach him how to fly a kite and that we could go to a nearby beach and fly it as high as it would go. Through my travels I would pick up things for our kite adventure and send them to him. In my trip to Japan, I found the most beautiful blue silk with gold threads（线）woven through it. Perfect kite materials! I sent it home with a picture book that would serve as a weight.

    When I got home at night, I found him sleeping sound, surrounded by all the items I had sent him for our kite. For the next week, we started to work on our masterpiece. We had our time together in the garage, after dinner. Finally, it was finished. The blue silk made it so beautiful. He was obviously eager to fly it soon. “We'll fly it tomorrow, right, Dad?” “Yes, if the weather is right,” I explained that we needed wind to lift the kite off the ground. I was afraid that it might rain. “We'll fly it because I'm going to pray with all my heart for the best kite weather.” He was right. I will never underestimate（低估）the power of a child's prayer any more.

    My son is a dad now, with children of his own. Though we are both busy, we still try to make time for each other. The other day, we met for coffee. While paying for our coffee, his wallet dropped on the ground and something fell out. Suddenly, a flood of memories washed over us as he put back his treasure into wallet—the blue silk with gold threads woven through it.

Harry, the first camel to arrive in Australia in 1840, was an unlucky beast. He was imported from the Canary Islands by explorer John Horrocks. On an expedition (探险), Horrocks picked up his gun in order to shoot “a beautiful bird to be added to the collection.” Perhaps Harry was an ecologist —- he lurched (突然倾斜), and the gun discharged, shooting Horrocks in the face.

    Horrocks not surprisingly died of his injuries, and his treatments ordered Harry to be shot. The first importation of a camel into Australia came to naught.

    In 1860, 24 camels arrived in Australia to be part of an expedition by explorers Robert O'Hara Burke and William John Wills. It was an unlucky expedition. The pair made one mistake after another, and ended up eating most of their camels, before starving to death.

    Six years later, more than 100 camels and their Afghan minders, arrived in Australia. This time it succeeded and thousands more camels followed.

    Sir Thomas Elder set up the first camel studs (种畜场) in South Australia, while others were set up in Western Australia. This time the camels bred (繁殖) like wildfire. They were used for working, rather than exploring expeditions.

    The imported Afghan cameleers were just as hardy and vital, leading camel trains across the cruel interior (腹地) of Australia, where few dared to go. The camels carried heavy packs of wool and supplies and opened up the desert areas as none had managed to do before. The train that does this crossing today is called The Ghan, in their honor.

    Motorization put these camel trains out of business, and many camels were turned loose. The camels loved Australia, and multiplied in amazing numbers. What is to be done with them?

    Not surprisingly they have become quite a tourist attraction and you can take a camel ride in the desert as the Afghan cameleers once did. But the fact is that camels create quite a problem in areas where they have taken over, as they damage local vegetation, muscle out native animals competing for food, and create chaos when they wander into settled area.
