If somebody decides not to get to know about current affairs related to science and technology, he or she will be separated from the real world. We must stay abreast with the new inventions so that we can predict the future. For example, if you know the current conditions of science and technology of 2012 well, you will better understand what will take place in 2012.          Therefore, you must gain enough knowledge on current affairs in science and technology. There are the Internet, newspapers and magazines to provide you with all the information of science and technology. Question: What does the author think of "techno-freaks"? Answer:

Q: Read the following article and answer the question. Article: Leaders of the World Health Organization say they are concerned about the air quality and health efiects on citizens during a recent outbreak of heavy pollution in Beijing.Still,they said they were unsure of the exact amount the air pollution takes on any person's body,casting doubts on local reports tying the area's dirty air to particular cases of illness.    Speaking at a briefing on Tuesday,the WHO's Western Pacific regional director, Shin Young--Soo,cited reports about poor air quality causing lung cancer in recent weeks. "The WHO is skeptical of the information,"she said."We're cautious of whether the illness is related to air po11ution. We know it has an impact on health,but we don't know how much."     The officials didn't cite particular reports.The comments follow a number of articles since late last year connecting some cases of diseases like lung cancer with pollution,.including one in November regarding an 8-year-old girl.    The health impact of Beijing's gray skies has been on the minds of many over the past week. Local authorities on Tuesday preserved an orange alert the city's second highest pollution-warning level--and again warned people to stay indoors.Experts widely agree that small particulates  known as PM2.5 carry significant short-and long-term health risks,particularly with children.Other studies find a certain link between pollution and shorter life spans.

Bernhard Schwartlander,the organization's China chief,said he is concerned and has been in contact with national authorities."There is no easy solution,"Dr. Schwartlainder said,adding that solving the problem requires managing industry and the economy.WHO leaders advised citizens.to stay indoors and limit exposure to the harmful particulates.When asked if wearing a face mask has any proven efficacy in preventing health effects of air pollution,Dr....

Q: Read the following article and answer the question. Article: Love to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all -- Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched  , the officials at the few schools around the world seem to agree. Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided with a device that helped record step count and calorie consumption over the entire period. All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to "sit still", older kids have a harder time adjusting to this unexpected freedom. American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire, became Europe's first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging. The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers -- it helps...
