When you arrive in a new country with a different culture you can experience different kinds of feelings and reactions. For example, you may feel confused and nervous, and like to depend on others. If you do experience these things, then you are probably experiencing culture shock. For example, coming to Australia from another country certainly gives you a chance to face many new things: the buildings look different, and the food is not what you are used to. You may not be able to speak with other people confidently. Learning to function effectively in a new culture is not easy. Meanings in cross-cultural situations are often unclear. This can be stressful because you are not sure what others expect of you or what you can expect of them. In these situations it is natural to feel anxious and frustrated . If you recognize that these feelings are a normal part of the experience of living away from "home", you may be able to deal with them more efficiently. Your sense of humor and openness will also help. As you gain greater understanding of the new culture, you can expect the stress to disappear. Dealing with culture shock needs a special effort, but it is the most important to remember that you are not alone in your feelings of distress. Most people in their first weeks and months in a new country experience similar reactions. Question: Why do people have many kinds of feelings in a new country? Options: A: Because they are surprised at everything they see. B: Because buildings are very beautiful. C: Because culture shock does have a great effect on them. D: Because they have to learn something quickly.

Article: Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity . In very cold climates, there is a constant danger of developing hypothermia , which is a life threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0degC. However, differences in persons and even the time of day can cause it to be as much as 6degC higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4degC. Below 29.4degC, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6degC. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7degC. In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7degC. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death. Question: Why can humans keep stable body temperatures in different seasons? Options: A: Because their bodies are unusually efficient. B: Because they experience different climates. C: Because they can adjust to cultural patterns and technologies. D: Because they have internal temperature regulating systems.

Article: Most of the guests who come on our trips have never been to Egypt before .We want to make everyone comfortable and at ease, but we do always get the same questions in advance of trip. So here I will give you some travel tips. What should I wear? If you're lucky enough to visit Egypt between November and February, pack a sweater. You'll need it----the desert gets rather cold at night. During the day, the temperature will be agreeable and comfortable. Any other time, pack as if you're going to Phoenix of Vegas in August. For the ladies, bathing suits are normal if there's a pool where you are going, but leave the string bikini at home -it is a Muslim country, after all. Last, if you are planning on visiting any mosques or certain parts of upper Egypt, ladies will need to plan on bringing something that comes at least to the elbow , and no shorts for men or women in those areas. What special things do I need to pack? One of my favorite things in the world to bring to Egypt is an Evian Mister, a sprayer with a fine mist of Evian water. You may be able to find it in your local drug store. Spray a little on your face or head , and your body temperature will feel like it's dropped 10 or 15 degrees. Other items include your camera, sun block and extra batteries. How do I communicate with home? Internet cafes are plentiful everywhere, especially in Cairo, Luxor, and Alexandria. If you have international calling on you phone, you should be able to use it-AT&T and Sprint both work internationally for sure, but make sure you have the international coverage. A satellite phone is best if you are certain to need coverage in the middle of the country, like while sailing up the Nile , but for most people these days a cell phone is fine. What medical preparation do I need? In a word: none! The one thing you may come down with in Egypt is politely called "Pharoah 's Revenge. " The thing that gets rid of pharoah's...

Options: A: describe a journey to Egypt to the tourists B: offer some practical tips on traveling in Egypt C: warn readers of the awful insects in Egypt D: appeal to more possible tourists to the journey
