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.

(Question)
One answer to the question of land shortage was suggested by an organization some years ago. A city was to be built at sea, housing 30,000 people. The suggestion was to shape the city like a harbor .The outer wall of the harbor would stand on steel columns resting on the sea-bed. Naturally this could only be where the water was fairly shallow. The people would like to live in flats in the fifty-metre high outer wall. The flats would be all face inwards, and would be made of concrete and glass. The glass would be specially made and colored to control the heat and strong light from the sun. The planners called this man-made harbor would be calm. On it would be floating islands carrying more building: a hospital, two theaters, museum, an art exhibition hall and a church. On one of the islands would be a special factory to take the salt out of sea water and turn it into fresh water. People living in the city could move around on small boats driven by electricity, so there would be no air pollution from the burning of gas. There would be platforms outside the man wall for ships bringing supplies. People could also travel to the mainland by motorboat or water plane. The purpose of the writer is _ . A) to suggest how new type of harbor could be built at sea B) to give a description of a new-type city C) to draw people's attention to the problem of air pollution D) to introduce a new way of building harbor-cities

Question: As young Chinese increasingly forget how to write characters because they don't have to, using keyboards and touch screen technology on mobile phones is changing the trend. For Yin Liang, a 26-year-old purchasing agent at a company, his embarrassment over forgetting how to write characters has gradually disappeared since he started to use the handwriting input method on his iPhone 4 a month ago. "When you write on the touch screen, you use your finger, instead of a mouse or keyboard," Yin says. "Actually, your finger is like a pen, writing the complicated characters that have long been spelled by pinyin, an alphabet-based input system. Whether typing on computers or texting on phones, most users in China type by phonetically spelling out the sounds of the characters and the software then gives a menu of characters that fit the pronunciation, so users only need to recognize the character. Handwriting technology on a mobile phone touch screen has been around for years and became popular with the iPhone, which recognizes the input and offers a wide selection of characters. "It's efficient and accurate," Yin says. Chinese characters are the oldest continuously used system of writing in the world, but as pinyin-based typing has become more widespread, youths have started forgetting how to write out characters. This was one of the main topics for debate at the first Cross-Straits Chinese Character Art Festival, held recently in Beijing, which attracted experts from Taiwan and the mainland. According to Zhang Zikang, president of the Culture and Art Publishing House, writing with a pen on the touch screen brings handwriting into the digital age. It is even better when you write with your finger, feeling the flow of the cursive script and the grace and art of Chinese characters, he says. "Smart gadgets don't take life from the square-shaped characters, instead they offer a new and advanced platform to show the charm of Chinese characters, which are always evolving," Zhang says. Which way is not mentioned in the passage to input characters on the phone? A) Taking pictures. B) Using a kind of alphabet-based input system. C) Spelling out the sounds of the characters. D) Using their fingers as pens to write.
