Do you suffer from cybersickness? The rise of mobile phones has been blamed for a number of social ills, but your smart phone may also be making you physically sick as well. Scientists have identified a condition called "cybersickness", which they say is the digital version of motion sickness. The phenomenon, which affects up to 80 percent of the population who own smart phones or tablets, leads to feelings of sickness and unsteadiness. It is caused by seeing fast motion on a screen, which covers anything from a car chase in a film to scrolling through web pages on your phone. The more realistic the visual content appears to you, the higher your chances of getting cybersickness are . The condition was identified in a piece in the New York Times in which British and US experts said that it needed solving. Motion sickness leaves sufferers feeling ill because they feel movement in your muscles and your inner ear but do not see it. The mismatch in digital sickness is the opposite--you see movement on the screen but do not feel it. The effect is the same and the symptoms include a headache, wanting to throw up, confusion and the need to sit down. Often cybersickness shows itself in a subtle way and sufferers put it down to stress or eyestrain. Steven Rauch, a professor of otolaryngology at Harvard Medical School, said: "Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don't agree, that's when you feel dizziness and sickness. " Some studies that have been carried out into cybersickness found that women are more _ than men, the New York Times reported. Those who have Type A' personalities--meaning they are confident and determined--are more likely to suffer from cybersickness as well. Among those who have reported experiencing the condition have been video gamers who spend hours playing fast paced games. Engineers at Oculus VR, the virtual headset manufacturer, have admitted that digital motion sickness is one of their biggest problems. What's the difference between motion sickness and digital sickness? A) Digital sickness means sufferers see movement but do not feel it. B) Digital sickness means sufferers feel movement but do not see it. C) Motion sickness means sufferers see movement but do not feel it. D) Motion sickness means sufferers don't see or feel movement

Most people who move to a foreign country or culture may go through some form of culture shock,and its degree is determined by the differences between cultures,the anxiety to adapt to a new culture and the familiarity with a new culture,etc.If you go,for example,to a culture that is far different from your own,you're likely to experience culture shock more sharply than those who move to a new culture knowing the language and the custom of it. It is important to understand and learn how to deal with culture shock if you are to adapt successfully to your new home's cultures.There are four general stages of cultural adjustment,and being aware of them helps you understand that culture shock won't last long.It's just a process you are going through rather than a constant situation. 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 thrilling and everyone will seem friendly and helpful.During this stage you are merely taking in these impressions passively. But it isn't long before the honeymoon stage gives way to the second stage--"the withdrawal stage".The excitement you felt before is gone and problems arise.The language is hard to learn,people are unusual and unpredictable,friends,are hard to make,and 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,and you will probably find yourself complaining about the new culture or country.This is the stage called "culture shock". At some point,if you can manage it well,you'll begin the transition into the next stage,"the recovery stage",in which you'll feel more confident functioning in the new culture.Customs and traditions are clearer and easier to understand.At this stage,you'll deal with new challenges with humor rather than anxiety. "The honeymoon stage" here refers to _ . A) the first month after the wedding B) the period of excitement C) the stage of adaptation D) the holiday for a newlymarried couple

Q: When I was three, my parents took me to have an operation in India, which stopped my eyesight from deteriorating . Several years later we moved to Pakistan, where I received 12 operations within one year and went completely blind. Later, I realized that the doctors used me as an experiment. I met my husband when he came over from India to study. I wanted to go to India to marry him, but it was almost impossible to emigrate. I made a crazy plan to cross the borders of several countries to get to India. I was arrested in the first country I escaped to. Back in Pakistan, I lost my job and was asked to sign a "never-to-escape" promise. Instead, when I got home, I made a cup of coffee and decided to make a formal application for emigration. _ , and people who applied to go to India found it hard to find a job in Pakistan while they were waiting. In the end, my husband managed to smooth the way for my emigration. We got married and had children. But after nine years, he died of brain cancer. I was helpless for a while, and then I learned to face reality optimistically. He taught us happiness came from inside us. Six years ago, I brought home a dog called Moritz from the seeing-eye dog centre. He was short with long ears. No one liked him because of his pathetic appearance. We were almost always together. Moritz could not leave me for even one minute. Now when I walk down the street, not like before, people will come up and say, "What a good seeing-eye dog!", and have a little chat with me as a normal creature. I'm now working for the Association of the Blind and I have many good friends, and a special friend in Hamburg. It is a wonderful feeling to speak freely with someone I can't see, to trust one another. The author went blind just because _ .
