People all over the world today are beginning to hear and learn more and more about the problem of pollution.Pollution is caused either by man's release of completely new artificial substances into the environment,or by releasing greatly increased amounts of a natural substance,such as oil from oil tankers into the sea. The whole industrial process which makes many of the goods and machines we need and use in our daily lives,is bound to create a number of waste products which upset the environmental balance,or the ecological balance as is also known.Many of these waste products can be prevented or disposed of.But while more and more new and complex goods are produced,there will be new,dangerous waste to be disposed of,for example,the waste products from nuclear power stations.Many people,therefore,see pollution as only part of a larger and more complex problem,that is,the whole process of industrial production and consumption of goods.Others again see the problem mainly in connection with agriculture,where new methods are helping farmers grow more and more on their land to feed our ever-increasing population.However,the land itself is gradually becoming worn out as it is being used,in some cases,too heavily,and artificial fertilizers can not restore the balance. Whatever its underlying reasons are,there is no doubt that much of the pollution caused could be controlled if only companies,individuals and governments would make more efforts.In the home there is an obvious need to control litter and waste.Food comes wrapped up three or four times in packages that all have to be disposed of;drinks are increasingly sold in bottles or tins which can not be reused.This not only causes a litter problem,but also is a great waste of resources,in terms of glass,metals and paper.Advertising has helped this process by persuading many of us not only to buy things we neither want nor need,but also to throw away much of what we do buy.Pollution and waste combine to be a problem everyone can help to solve by cutting out... Much of the pollution could be controlled if only . A) people would pay more attention to the problem B) governments would take effective measures C) all sides concerned would make more efforts D) farmers would use less artificial fertilizers

Miguel's co-workers don't quite understand him. One day he is smiling and friendly, a real team player. The next day, he is cross, getting angry over minor things, especially when asked to improve one of his designs. Identifying your personality characteristics is the first step in developing a good attitude. Are you a positive, confident person or are you shy and reserved? Do you face problems, looking for solutions, or do you feel someone to blame? Characteristics define you. They help you succeed, or they hold you back. Self-awareness, or understanding the factors that make up your personality, is an important step towards happiness, and happiness is the key characteristic of a good attitude. To become self-aware is to be aware of both your good and bad characteristics. What are the characteristics that people compliment on you? Are you dependable", "responsible" or "solid"? Pay attention to the compliment because they are a confirmation of your strongest characteristics. You can use these characteristics to create an even better image. People form opinions about you. Whether they are right or wrong doesn't enter the question. You, however, can change their opinions by demonstrating the personality characteristics and attitudes that match the way you want to be viewed. In becoming self-aware, understanding how others see you is an important step. This can be painful; but if you are brave enough to try it, it can be an excellent growth experience. Change is not easy, especially when it has to do with your behaviors. You should break the behavior change into small steps because small steps are easier to achieve and more likely to last. The change will be permanent if you want to change for yourself. The purpose for writing this passage is to _ . A) help you to get along well with others B) give you advice on how to be happy C) help you to get rid of our bad behaviors D) help you to develop a good personality

Q: If you are looking for a creative solution to a piece of work or a school assignment,don't lock yourself up in a quiet room. A new study suggests that moderate background noise is a better spur to creative thinking than the sound of silence,Time magazine reported. A paper published in the Journal of Consumer Research says that the perfect working environment should buzz with a little noise. Researchers found that test subjects were at their most creative when background noise was measured at 70 decibels,the level one might find in a busy coffee shop. A nearly silent environment(50 decibels)was too quiet. Turning up the volume to 85 decibels (a jackhammer tearing up the pavement outside your building) was counterproductive-the noise became a distraction. The researchers asked 65 students at the University of British Columbia,Canada,to perform various creative tasks while noises recorded at a roadside restaurant were played in the background. In one experiment,scientists asked participants to brainstorm ideas for a new type of mattress . Test subjects had the most successful discussions when the noise in the background was noticeable but not too loud. While a quiet environment may make it easier to read a book. the authors of the study say that moderate background noise creates just enough of a distraction to force people to think more imaginatively, without breaking their focus so completely that they can't think at all. Should we all head for Starbucks to get creative? Not necessarily. Researchers found limited work time surrounded by the low-level noise of a coffeehouse is what really stimulates creativity. Equally, working in a care environment isn't good for everybody. The productivity boost was most obvious among those who were naturally creative to begin with. Which best describes the writer's tone in the passage? A) Negative. B) Objective. C) Enthusiastic. D) Doubtful.
A: B

As hand-held devices such as smartphones are becoming more common, users are reporting some new physical problems. Florida chiropractor Dean Fishman began noticing an increased number of patients talking about neck and shoulder pain. He discovered these symptoms were due to the overuse of hand-held devices, particularly the action of bending the neck, and then _ the term "Text Neck." As if the painful symptoms weren't bad enough, Fishman warns that an untreated case of Text Neck could lead to permanent spinal damage. Other doctors have warned about "iPad Hand," a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain. In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic principles: Avoid awkward positioning. Don't strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren't leaning over for a long period of time. Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes. When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle. Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you'll be resting both hands on the keyboard. And since you won't be holding the tablet, you'll be less likely to experience hand or arm pain. In which magazine would you most likely find this article?
