Cats like climbing trees and there are logical reasons behind this behavior. Interestingly, due to some of their physical features, cats will meet trouble getting down from the trees after climbing up, which may seem unusual. There are several reasons why cats climb trees, mostly to do with defensive purposes. Cats, as predators , like to understand their environment well. As they are small animals, their scope of vision is considerably smaller. Cats often climb trees to get a better view of their surroundings to help them see any potential dangers. While cats are predators, they are also easy to get attacked from larger animals, such as dogs or even other cats. A tree often provides a safe hiding place. In the wild, cars climb up trees to give them a resting or napping place that is out of predators' range. It also helps disguise their presence. Some cats may climb trees for fun, on occasion, or possibly to work on improving their climbing abilities. Small cats frequently test out their claw skills by trying to climb up anything and everything, from bookcases to trees to a person's leg. Climbing practice is good for cats; it can improve their strength and flexibility and teach them an important defensive skill. If a cat has gotten up a tree and cannot get down, the owner may wonder why its remarkable climbing abilities only work in one direction. A cat's claws curve inward, allowing it to grip onto surfaces while going up head first. Unfortunately, this useful climbing curve does nothing to help the animal get back down again. Eventually, most trapped cats will either jump out of the tree or realize that they can get down by going tail first. Either way, a cat up a tree is usually nothing to worry about; they are intelligent animals and will figure out how to get down sooner or later. What does this text mainly talk about. A) Why cats like to climb trees. B) Why cats can't climb down a tree. C) How cats manage to climb down a tree. D) What owners do to help cats down a tree.

Children whose minds wander might have sharper brains, a research suggests. A study has found that people who appear to be often distracted   have more "working memory", giving them the ability to hold a lot of information in their heads and control it cleverly. Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers' instructions or remembering dictated   sentences. During the study, volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering. At the end, volunteers measured their working memory capacity   by their ability to remember a series of letters mixed with simple maths questions. Daniel Levinson, a professor at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported "more mind wandering during these simple tasks", but their performance did not _ . The results, published online in the journal Psychological Science, appear to confirm former research that found working memory allows humans to deal with multiple thoughts at the same time. Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said, "What this study seems to suggest is that, when surroundings for the task aren't very difficult, people with additional working memory capacity use them effectively to think about other things besides what they're doing." Working memory capacity is also associated with general measures of intelligence, such as reading comprehension and IQ scores. Dr Smallwood added: "Our results suggest the sorts of planning that people do quite often in daily life - when they are on the bus, when they are cycling to work, when they are in the shower - are probably supported by working memory." What's the text mainly about? A) How the working memory works in the daily life. B) Wandering minds might have brighter brains. C) Why people's minds wander while working. D) Working ability can be improved by wandering minds.

(Question)
Nowadays, people have a heated discussion on whether the pressure on international sports players kills the essence   of sport --the pursuit of personal excellence. Children kick a football around for fun. When they get older and play for local school teams, they become competitive but they still enjoy playing. The individual representing his country cannot afford to think about enjoying himself; he has to think only about winning. He is responsible for the entire nation's hopes, dreams and reputation. A good example is the football Word Cup. Football is the world's most important sport. Winning the World Cup is perhaps the summit of international sporting success. Mention Argentina   to someone and the chances are that he'll think of football. In a sense, winning the World Cup put Argentina on the map. Sports fans and supporters get quite _ about the World Cup. People in England felt that their country was somehow important after they won in 1966. Last year thousands of Scots sold their cars, and even their houses, and spent all their money traveling to Argentina, where the finals were played. So, am I arguing that international competition kills the idea of sport? Certainly not! Do the Argentineans really believe that because eleven of their men proved the most skillful at football, their nation is in every way better than all others? Not really, But it's nice to know that you won and that in one way at least your country is the best. What does the speaker mean when he says "In a sense, winning the World Cup put Argentina on the map"? A) Winning the World Cup makes Argentina a football power in the world. B) Winning the World Cup gives weight to Argentina's position in the world. C) Argentina is not important before it wins the World Cup. D) Argentina is world-famous for its football because of its obvious position on the map.
