Article: Blogging may have psychological benefits for teens suffering from social anxiety, improving their self-esteem and helping them relate better to their friends, according to new research published by the American Psychological Association. "Research has shown that writing a personal diary and other forms of expressive writing are a great way to release emotional distress and just feel better," said the study's lead author, Meyran Boniel-Nissim, PhD, of the University of Haifa, Israel. "Teens are online anyway, so blogging enables free expression and easy communication with others." Blogging has a stronger positive effect on troubled students' well-being than merely expressing their social anxieties and concerns in a private diary, according to the article published online in the APA journal Psychological Services(r). Opening the blog up to comments from the online community intensified those effects. The researchers randomly surveyed high school students in Israel, who had agreed to fill out a questionnaire about their feelings on the quality of their social relationships. A total of 161 students -- 124 girls and 37 boys, with an average age of 15 -- were selected because their scores on the survey showed they all had some level of social anxiety or distress. All the teens reported difficulty making friends or relating to the friends they had. The researchers assessed the teens' self-esteem, everyday social activities and behaviors before, immediately after two months and after the 10-week experiment. Four groups of students were assigned to blog. Two of those groups were told to focus their posts on their social problems, with one group opening the posts to comments; the other two groups could write about whatever they wanted and, again, one group opened the blog up to comments. The number and content of comments were not evaluated for this experiment. The students could respond to comments but that was not required. Two more groups acted as _ -- either writing a private diary about their social problems... Question: The selection of students for the experiment was largely based on _ . Options: A: their social relationships B: their self-esteem C: their problems in social life D: their willingness to fill out a questionnaire

I didn't think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children. "Are you all sick?" I asked suspiciously. "Yes," she said weakly and lowered her head. But when it came to descriptions of their presenting problems, things got a little vague. Two of the children had headaches, but the headaches weren't accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it. Something was wrong, but I didn't say anything but explained that it might be a little while before a doctor saw her. She responded, "Take your time; it's warm here." On a hunch , I checked the chart after the admitting clerk had finished registering the family. No address---they were homeless. The waiting room was warm. I looked out at the family huddled by the Christmas tree. The little one was pointing at the television and exclaiming something to her mother. The oldest one was looking at an ornament on the Christmas tree. I went back to the nurses' station and mentioned we had a homeless family in the waiting room. The nurses, grumbling about working Christmas, turned to compassion for a family just trying to get warm on Christmas. The team went into action, much as we do when there's a medical emergency. But this one was a Christmas emergency. We were all offered a free meal in the hospital cafeteria on Christmas Day, so we claimed that meal and prepared a banquet for our Christmas guests. We needed presents. We put together oranges and apples in a basket. We collected from different departments candies, crayons and other things available that could be presents. As seriously as we met the physical needs of the patients that came to us that day, our team worked to meet the needs, and... Question: It can be inferred from the text that _ . Options: A: The author didn't think there would be any patients on Christmas Day B: The woman was uncomfortable when she lowered her head C: The family appeared in the emergency room on Christmas Eve D: The woman and four small children were satisfied and grateful

Article: A gadget which makes water out of air could become the greatest household invention since the microwave.http://www.ks5u.com/gaokao/beijing/ Using the same technology as a dehumidifier ,the Water Mill is able to create a ready supply of drinking water because it can always get from an unlimited source--the air.http://www.ks5u.com/gaokao/beijing/ The company behind the machine says not only does it offer an alternative to bottled water inhttp://www.ks5u.com/gaokao/beijing/ developed countries, but it is a solution for the millions who face a daily water shortage.http://www.ks5u.com/gaokao/beijing/ The machine works by drawing in wet air through a filter and over a cooling instrument which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights. Inventor Jonathan Ritchey said, "The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable." The machine, which is about 3 feet wide, is likely to cost PS800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly calculates that a liter of water costs around 20 pence to produce. Environmentalists state that half the world's population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking. The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won't be much of a problem. Question: What do we learn about the machine? Options: A: It works in the same way as microwaves. B: It is very expensive for families to afford. C: It absorbs wet air and turns it into water. D: It helps to make the water clean to drink.http://www.ks5u.com/gaokao/beijing/
