Read the following article and select the best answer. Article: Art is everywhere in our lives.Every manmade object is linked with art--a house,a motor car,a bridge,a chair,a teapot,or a piece of cloth.Throughout history,humans have made articles for a wide variety of purposes;generally for everyday practical requirements.The style of practical objects reflects the outlook and the spirit of the times in which they are made and in consequence style is constantly changing. It seems that humans possess a natural urge to improve constructed objects with decoration:sometimes for beautification,sometimes for religious reasons,sometimes to show off their wealth and power,and sometimes to tell a story.Decoration is not art in itself.Unnecessary decoration can ruin the form and perhaps the function of an object,but when decoration is used with care,it can beautify,produce variety,and add interest. The first essential in every creation is that it should properly _ its purpose;for instance,a teapot should pour perfectly,an easy chair should provide comfortable relaxation,a block of flats should be a pleasant place in which to live,and a factory or commercial building should be a suitable building in which to work. The second essential is that an object should please the eye with its form,line,proportion ,colour and texture ,and it should be capable of inspiring the emotions.For example,contemporary furniture designers must think of form,function and structure,and have taken their lead from the outstanding Scandinavian designs of Denmark,Finland and Sweden,whose preference was for simple functional furniture to suit the architectural environment of the day.Heavy furniture is no longer desirable,and by contrast,modern furniture is often characterised by its good proportion,pleasing lines,simple fittings and attractive structures. Motor vehicles are a perfect example of how design has changed to suit function.Early car design was greatly influenced by the horsedrawn carriage,but today we find functional design satisfying every requirement of practical use and good appearance.Designs... Question: What point does the writer make about decorating objects? - It is something people have always done. - It can show the object has a range of functions. - It always improves the appearance of an object. - It is usually done to make the object more noticeable.
It is something people have always done.

Read the following article and select the best answer. Article: Most damagingly, anger weakens a person's ability to think clearly and keep control over his behaviour. The angry person loses objectivity in evaluating the emotional significance of the person or situation that arouses his anger. Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels as an appropriate expression of anger resulting from one person's awareness of insulting behaviour on the part of another. Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG measures of electrical activity show balanced activity between the right and left prefrontal areas. Behaviourally this corresponds to the general evenhanded disposition that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren't balanced and, as a result of this, we're likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative. Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as offensiveanger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approachandconfront behaviour is accompanied by a leftward prefrontal asymmetry of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy towards the individual who is bringing... Question: What changes can be found in an angry brain? - Balanced electrical activity can be spotted. - Unbalanced patterns are found in prefrontal areas. - Electrical activity corresponds to one's behaviour. - Electrical activity agrees with one's disposition.
Unbalanced patterns are found in prefrontal areas.

Q: Read the following article and select the best answer. Article: The cost of college textbooks has risen sharply from 2002 to 2014. As a result, students have to look for other less expensive options , such as renting books. Now, they find another way, that is, using textbooks on the Internet, uploaded by other students. It is hard to know how popular this practice will be, but many college students around the country are uploading their expensive college textbooks onto the Internet, so that other students can download them for free and avoid the big fees. A year ago, a student wrote a blog called Children of the Stars about a professor who insisted that students buy the newest edition of a specific sociology book for more than $200 and didn't allow them to purchase an older paperback edition of the same book for $5. The student wrote, "The newest edition of the book is so expensive. Fortunately, we found the electronic one online, which is very cheap. This is why we downloaded. " The blog is followed by a list of websites where people can download books. Curious about how varied the selection of books was and how easy it was to download them, Vocativ.com decided to do an experiment. The workers of it picked five typical and important courses of freshmen and tried downloading all these textbooks on the websites offered by the student who wrote Children of the Stars. They typed the titles of these textbooks into a computer, and found them immediately. Within minutes, they had four textbooks on their hard drive. It is illegal to upload or download copyrighted materials without permission, but students still do it due to its advantages. Besides, schools haven't taken action to stop it. Question: According to the passage, why do many students choose to download textbooks? - Because it is lower in cost. - Because it is required by their teachers. - Because it can help them gain the latest knowledge. - Because it can do less harm to the environment.
A: Because it is lower in cost.

Read the following article and select the best answer. Article: Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert. Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge(7,200,000-cubic-foot)glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon "ocean." The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming. The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient , these "colonists" had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1's -- that is, Earth's most basic environment questions. Question: This passage primarily deals with _ . - conditions of life in Biosphere 2 - building controlled environments on other planets - why Biosphere 2 failed in the past - what makes a good biosphere colonist
(Answer)
conditions of life in Biosphere 2
