-American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working,but still all those hours in windowless offices with artificial light can have an influence. A few green additions could have a large effect on worker happiness,according to the survey led by Tina Cade from Texas State University. "We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job," Cade told LiveScience. "We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places." The team surveyed 450 office workers in Texas and the Midwest,asking questions about job satisfaction and the work environments. When asked about their overall life quality,82 said they felt "content" or "very happy". Only 69 percent of those who work with plants but without windows,and 60 percent of those who have windows but no plants, said they felt this way. The group of people who work without plants or windows were  the most dissatisfied,with only 58 percent of them saying that overall they were "content" or "very happy". While no one who works with plants,windows,or both reported they felt "miserable", 0.8 percent of those who work in offices without either said they were "miserable". "I was really surprised that having a plant in your office appeared to be more beneficial than having a window in your office," Cade said. "Everybody says, 'I need a window!' but actually it seemed like a plant could be a suitable alternative." According to the survey,the group of people who work without plants or windows   _  . A) didn't feel content at all B) all suffered from work pressure C) were the most dissatisfied D) worked with low efficiency

Attending the Space Camp organized by NASA at prefix = st1 /Huntsville,Alabamais every kid's dream. It gives them the real life experience of what it is like to be an astronaut. It enriches their life with the most meaningful and interesting experiences. Most of these one-week programs are combined with other community programs.  As expected, there is an age limit at the Space Camp in Alabamawith the full camp program being offered only to kids of twelve and above. Many of the activities organized at the camp are likely to be difficult for younger kids, and kids need to be old enough to stay for the week away from home. However, some special programs are offered at the center even for younger kids.  The programs and activities at Space Camp are to awaken creativity. There are exercises in classes and discussions about the history of the space program. These classes include the Russian space program as well as the United Statesprogram. Trips to the museum are also provided for an educational experience.  All those who attend the Space Camp go through a sort of training. They wear space suits to get the feeling of being an astronaut. They are taken into simulators   to learn how to fly spacecrafts like the shuttle. And they experience the feeling of weightlessness in the zero gravity simulations. What's more, they even have equipment designed to give them the experience of walking on the moon.  Space Camp is an effective and fun way to bring an interest in space and science. Kids will go through a practical program in a learning atmosphere that transports them far away from their location in Huntsville.Alabama. Kids under twelve can't go to the Space Camp because A) many of the activities are very dangerous B) their parents don't allow them to go C) there aren't any special programs at the center D) they are unlikely to look after themselves well

Q: Alfred Carlton Gilbert(1884-1961) was a man of many ideas and talents. As a small boy, he kept trying new things. At age 12, he started a sports club for his friends and got their school to have a field day with active games and prizes. As he grew and practiced, Gilbert became skilled at pole vaulting , pull-ups, the long jump and football.  Gilbert broke the world record for pull-ups in 1900 and the distance record for running long dive in 1902. And he won a gold medal in the pole vault at the Olympic Games in 1908. By that time, he had nearly finished medical studies. Choosing not to make medicine his career, Gilbert co-founded Mysto Manufacturing, a manufacturer of magic sets, in 1907. Gilbert had amused his friends and earned college money by doing magic tricks, so he knew what was needed. One day, Gilbert saw workers using steel girders  to build towers for power lines. That gave him the idea for the Erector Set, a popular construction toy. In 1917, the Council of National Defense thought no toys should be produced for Christmas because the country was fighting in World War I. Gilbert and other men from the Toy Manufacturers of America went to Washington, with about 40 different toys. They had 15 minutes to speak. This meeting was at the end of a long, hard day. Gilbert told the government men at the meeting how toys helped children learn. His helpers brought out the toys. Soon, the tired government men were on the floor, playing with building sets, models of navy ships, and other toys. The time limit was forgotten; so was the Christmas toy ban . Gilbert spent the rest of his life improving erector sets. His company made and sold the sets, plus chemistry and other science sets and toy trains. He made items for homes, businesses, and the army. When he died in 1961, he had 150 patents  for his many inventions. But his main joy was in helping children learn and have fun at the same time. What would be the best title for the text? A) An easy way into the sporting circle. B) The man who saved Christmas. C) Influenced of toys on children D) The amazing Mr. Gilbert.

Chronic pain relief  Music also has the ability to reduce chronic pain. In fact, according to a paper published in the Journal of Advanced Nursing, music can reduce chronic pain by 21%.
