It can be caused by illness or fever, tiredness, stress or anxiety. It is thought to occur in the beginning, slow-wave stages of non-rapid eye movement sleep before dream sleep. It may be related to the lack of magnesium   , and it is very possible that hormonal changes in body could cause it. Certainly a child is more likely to be a sleepwalker if one of his parents suffered, too . Sleepwalking itself is not dangerous and is generally not a sign of any more worrying problems. But if your child sleepwalks regularly, you have to take safety measures to make sure that he doesn't hurt himself while sleepwalking.

Q: Read the following article and answer the question. Article: I came to India a year ago to find a village in which I could live and write but it was many months before I settled down happily in this Himalayan community.I wasted a lot of time looking for the "typical" village, yet no such thing exists. Conditions vary too widely.But the villages I stayed in had much in common--poverty, dirt, ignorance. Often the villagers themselves were puzzled, suspicious. Why had I come? I had put aside my work as a political journalist because my ideas had changed. I had come to believe that what was happening in the Third World was more important than anything else. But to understand how three quarters of the world's people live, and how their future might affect ours, I felt that I first had to try and share their way of life.In the end I chose a mountain village because it was a little cooler than those in the plains. I took the bus from town along a bumpy road. Then came a rough walk down a steep path to the river. After this I began the climb into the Mils. Whenever I stopped to catch my breath, there was a magnificent view. After several hours' walk the village came into view. Question: Before coming to India, the writer  _  . Answer: | OPTIONS:
- had been a successful politician
- had made a decision to work for India
- had studied India culture for some months
- had worked for newspapers and magazines
A: had worked for newspapers and magazines

Q: Read the following article and answer the question. Article: If you really want to go green, here's good news: eating green is good for you. The very foods with a high carbon cost---meat, pork, dairy products, processed snacks---also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, whole grains, fish and lean meats like chicken---a diet that's eco- and waistline-friendly. Eating green can be healthier and beneficial to the climate. It may be hard to believe that a meal at McDonald's produces more carbon than your trip to a far away place. More than 37% of the world's land is used for agriculture, much of which was once forested. Deforestation   is a major source of carbon. The fertilizer   and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate. The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent   amount of grains, fruits or vegetables. What's more, the majority of cattle in the U.S. are fed on grain and loads of it---670 million tons in 2002---and the fertilizer used to feed that creates separate environmental problems. Focus on eating lower on the food chain, with more plants and fruits and less meat and dairy. It's simple. We can change today what goes into our bodies for the health of our planet and ourselves. Question: What will not lead to carbon in the agriculture? Answer: | OPTIONS:
- Deforestation
- Fertilizer
- Machinery
- Grains
A: Grains

Q: Read the following article and answer the question. Article: The whole morning we just checked our own things. We were looking for items to give away. We thought of blankets, food and clothing. Our aim was not to find things we no longer wanted, but things we use every day and would be useful to others. We made up boxes with the things and added some small toys. Inside the boxes a simple letter was placed, reading: "Please take these items and know that your life is important. Times are difficult but they will pass. We share what we have, believing it will matter. Use the blanket to stay warm. Be safe and know that the human spirit can overcome anything. Don't hold your head down. Someday please do the same when you can. How you do it and when, your heart will tell you. This kind act was not because the phone rang or for any reason. It was simply because it was the right time to do. We have often seen homeless people at the park where we left the belongings. The city would say that it isn't a problem but I see the lives walking to and from it. I noticed that my wife had put her favorite green coat into one of the boxes. I asked if she was sure about it and she simply replied that it had a hood  . She liked the coat but knew the hood could shelter  someone from the rain. We don't know where these gifts of compassion will go. We never go back and see what happens. It's unimportant. The right things will find the right people and that is all that counts. On the way my wife started to cry. When I asked why, she said because some things felt so right. Question: The couple liked this kind act because   _  . Answer: | OPTIONS:
- they thought it was the right thing to do
- they had a good habit of saving things
- they often received telephone calls for help
- they hated being troubled by homeless people


assistant: A: they thought it was the right thing to do
