The Internet is now a central part of everyday life. The number of Internet hours in the West is increasing each month, but online addiction is still not attracting a great deal of attention. Perhaps one reason Internet addiction has not _ in the West is that there are too many other vices available. In a society ly open to sex, gambling, alcohol and drugs, computer games are not always appealing to young people. In fact, there is almost a shame attached to playing online games. Many consider it an "uncool" thing to do. They would rather spend their free time meeting friends. But this is not to say that people don't do it. One website, wowdetox.com, still offers support to recovering "addicts". One user posted on the website: "I would play all night and spend all day sleeping. I just quit a month ago. Best decision ever." This is just one example from around 1,660 pages of confessions . Still, computer game addiction is not officially recognized in the West. Just last years, the American Medical Association refused calls to have computer game addiction classified as a disease, saying that, "Nothing suggests it is a complex disease similar to alcoholism." Online gaming is more personal in the West. It is rare for people to visit Internet cafes or play with friends at home. After all, the majority of households have their own fast Internet connection. This removes the social joy with friends. And this choice of playing alone is not very appealing to many people. According to the passage, which of the following is TRUE in the USA? A) Personal playing online is attractive. B) Computer game addiction is officially recognized. C) It is a shame to play too much online games. D) Online game addition is considered similar to alcoholism.

Everyone agrees that it's necessary to reduce carbon emissions around the world. There is less agreement over exactly how nations should go about achieving a more carbon - free planet. Thus, the environmental equivalent: cap - and - trade carbon emissions, or place a carbon tax on all users? With cap - and - trade programs, governments limit the level of carbon produced by an industry. Companies that hold their emissions below the _ can sell their remaining allowance on a carbon market, while companies that go beyond their limit must purchase credits on that market. Carbon taxes are more straightforward: a set tax rate is placed on the consumption of carbon with the idea that raising the price will encourage industries and individuals to consume less. At the moment, cap-and-trade has the upper hand, but doesn't defeat the tax just yet. Supporters of the tax argue that a cap - and - trade system would be too difficult to administer - and too easily gamed by industries looking to sidestep emissions caps. Cap-and-trade advocates contradict that like all other flat taxes, a carbon collection would relatively burden lower - income families, who spend a greater percentage of their income on energy than rich households. So which system will have a larger effect on carbon consumption? A 10% carbon tax might reduce the demand for carbon about 5 % or less, according to an analysis by the Carbon Tax Center, an environmental advocacy group. That may not be enough. Businesses and governments haven't figured out how the two competing systems can work together, but in the end, the world may need both. Carbon taxes work by _ . A) burdening well - off families B) encouraging industries to consume carbon C) raising the price for carbon consumption D) limiting the carbon consumption of industries only

Q: _ (from How Do Animals Move?) Many animals scurry up tree trunks to escape enemies or find food. Some live in the treetops. Many of these animals are not only expert climbers, but they also have found interesting ways to get from tree to tree. How Do Animals Adapt?andHow Do Animals Move? are comprehensive explorations of animal adaptations and movement for young readers. Both are part of a 21 book series,The Science of Living Things. InHow Do Animals Adapt?readers learn how animals adapt to survive with respect not only to climate, darkness, food and defenses but also to offspring and people. These adaptations are well explained in double page spreads with examples clearly depicted in photographs and diagrams and developed through their accompanying captions . As the title suggests, movement is the focus ofHow Do Animals Move?Beginning with a description of the explanation of movement, the reader is exposed to the many different ways of animals movement in the air, on land, under ground and in the water. Several unconventional variations (e.g. looping of inchworms, the rectilinear motion of snakes) are included. Once again, the photographs and diagrams plainly support the double page spread discussions of animal movement. The language of both titles is simple enough for young readers without talking down to them. In both books, terminology is featured in . Some of these words are explained in the basic glossary while the majority are explained clearly in the text. Many of these terms provide readers with some fascinating, uncommon words (e.g. brachiation, potassium, skein, and estimate). As do many of Kalman's book, both of these titles have a table of contents, glossary and index which are all enough to introduce young readers to the nature of these tools. Both titles would make excellent additions to any science collection for young readers. The passage is a/an _ . A) report B) review C) advertisement D) journal

Answer: B
You do not need every word to understand the meaning of what you read. In fact, too much emphasis on separate words both slows your speed and reduces your comprehension. First, any habit which slows down your silent reading to the speed at which you speak or read aloud, is inefficient. If you point to each word as you read, or move your head, or form the words with your lips, you read poorly. Less obvious habits also hold back reading efficiency . One is "saying" each word silently by moving your tongue or throat; another is "hearing" each word as you read. These are habits which should have been outgrown long ago. The beginning reader is learning how letters can make words, how written words are pronounced, and how sentences are put together. Your reading purpose is quite different, which is to understand meaning. It has been supposed that up to 75% of the words in English sentences are not really necessary for expressing the meaning. The secret of silent reading is to find out those key words and phrases which carry the thought, and to pay less attention to words which exist only for grammatical completeness. An efficient reader can grasp the meaning from a page at least twice as fast as he can read the page aloud. He takes in a whole phrase or thought unit at a time. If he "says" or "hears" words to himself, they are selected ones, said for emphasis. While reading, efficient readers usually _ . A) move their eyes quickly B) take in whole phrases or thought units C) point at key words D) read only important points for speed
