Sea turtles come in many different sizes, shapes and colors. The shell of each sea turtle species is different in length, color, shape and the arrangement of the scales . Sea turtles do not have teeth but use their jaws to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have _ out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain close ties to land. Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries still remain. Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years. What would be the best title for the text? A) Mysteries About Sea Turtles B) Baby and Female Sea Turtles C) The Growth of Different Sea Turtles D) The Characteristics of Sea Turtles

Economists have studied how markets work for a long time.Generally,they work well.But markets do not always perform as expected.Jean Tirole of France won the Nobel Prize in Economics for studying why markets are imperfect,or inefficient,and what governments can do to regulate them. The Nobel prize committee announced the $1.1 million prize in Stockholm to Jean Tirole.Itcalled Mr.Tirole"one of the most influential economists of our time".The organization said he had done important research in a number of areas.But it said,"most of all he has clarified how to understand and regulate industries with only a few powerful firms." Mr.Tiro1e works at the Toulouse School of Economics in Toulouse,France.He is 61 years old.For about 30 years,Mr.Tirole has researched periods when markets failed,that is,when they did not provide good results in price and competition.He looked at how a small number of large companies,or even a single company,can strongly influence industries. Banking and telecommunications were among the industries he studied. The Nobel committee said that unregulated markets often produce socially _ results. They can result in higher prices or companies that use their market position to block others* The committee said it chose Mr.Timle because he thought about how best to regulate markets.For example,Tore Ellingsen,Chairman of the committee that awards the economics prize,says Mr*Tirole showed the need to develop better rules for the banking industry.This became urgent after the world financial crisis of 2008--2009. The economics Drize is called the Bank of Sweden Prize in Economic Sciences in Memory of Alflred Nobel.Alfred Nobel did not establish the prize.It was first presented in 1969. The passage tells us that Jean Tirole _ . A) has studied the economics in Sweden B) is the first to win the Nobel Prize in Economics C) is highly praised by Chairman of the committee D) has made regulations for large companies

Ques: I come from a city on the United States'east coast. It's a ten-hour flight for me to get home from Shanghai. When I got off the plane, I took photos of the blue sky and white clouds along the way. After two weeks, I returned to Shanghai. Much to my surprise, the blue sky in Shanghai that I liked before was not as blue as that in the US. I couldn't help wondering what had happened. A few days later, I went to tour Waitan (a famous tourist attraction in Shanghai) by the Huangpu River with some of my friends. There we saw five Ferrari sports cars by the side of the road. The red and yellow cars looked so nice that everyone was looking at them. However, when I turned my head, I noticed the sky over Waitan, I was shocked to find that the buildings in the Lujiazui area on the other side of Huangpu River could hardly be seen. It was then that I realized that Ferrari cars could be bought with money, but a blue sky couldn't. Shanghai is an important economic and trade center in China. It has made great contributions to the whole nation's economic development. However, we need to protect the environment during economic growth. Pollution is poisoning our air and our rivers. Without clean air and rivers, how will people be able to survive? What is the best title for this passage? A) Money Can Buy Ferraris, But Not a Blue Sky B) Where People Should Live C) Different Opinions on Cars D) Different Places Have Different Skies

Manners nowadays in metropolitan cities like London are practically non-existence, it's nothing for a big, strong schoolboy to elbow an elderly woman aside in the dash for the last remaining seat on the tube or bus, much less stand up and offer his seat to her. This question of giving up seats in public transport is much argued by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy , ) and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it is not agreed, however, that young men should stand up for younger women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Are we really so lost to all ideals of unselfishness that we can sit there indifferently reading the paper or a book, saying to ourselves "First come, first severed", while a grey-haired woman, a mother with a young child stands? Yet this is all too often seen. Older people, tired and quick-tempered from a day's work, are not angels, either-far from it. Many a brisk argument or an insulting quarrel breaks out as the weary queues push and shove each other to get on buses and tubes. One cannot commend this, of course, but on does feel there is just a little more excuse. If cities are to remain pleasant places to live in at all, however, it seems imperative , not only that communications in transport should be improved, but also that communication between human beings should be kept smooth and polite. All over cities, it seems that people are too tired and too rushed to be polite. Shop assistant's won't bother to assist, taxi drivers growl at each other as they dash dangerously round corners, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on and so on. It seems to us that it is up to the young and strong to do their small part to stop such deterioration . According to the passage communication between human beings would not be smoother unless _ . A) people were more considerate towards each other B) people were not so tired and quick-tempered C) women were treated with more courtesy D) public transport could be improved.
