The weather predictions for Asia in 2050 read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring. In the decades to come, Asia---home to more than half the world’s 63 billion people-will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.
“It’s not a pretty picture,” said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters. According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food, water and other resources. Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.
The year before, a winter cold struck and a summer heat wave killed more than 2,000 people in India.

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson"s disease, Alzheimer"s disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson"s disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.

Popeye the Sailor first became a popular cartoon in the 1930s. the sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
小题1:A good title for this reading passage is______.| A．Popeye the Sailor | | B．The Truth About Spinach | | C．A Mistake with Numbers | | D．Folic Acid Makes You Strong |
小题2:Why did many people eat spinach after they saw Popeye the Sailor?| A．People liked folic acid. | | B．They thought Popeye was funny. | | C．Spinach had a lot of iron. | | D．They thought spinach made them strong. |
小题3:A research group told people that spinach______.| A．made Popeye strong | | B．was a green vegetable | | C．had less iron than other green vegetables | | D．had more iron than other green vegetables |
小题4:The reading passage says that perhaps Popeye got his strength from______.| A．iron | B．spinach | C．folic acid | D．exercise |

You have some great ideas. But they don’t come out because of what your friends say or because you think that only a few people can be creative geniuses(天才). And, you, of course, think that you couldn’t be one of them. But actually, this is not true at all.
Anyone who is a creative genius will tell you that creativity is very much like a muscle that needs to be developed. If you don’t learn how to develop creative thinking, this skill, just like a muscle, will become poor and useless. On the other hand, keep working at it, and this skill will soon be ready for action whenever you need it. So how do you develop your own personal style of creative thinking?
You should realize that your brain has a greater capacity (容量) and a higher speed than the world’s biggest and fastest computer. So it’s important to get as much information as you can every day. Read, watch and listen to everything around you —good and bad. The more you know, the more you’ll want to know, and the more your brain will be exercised.
Try something new every day and let your experiences show you more about the world and people around you. You need to step out of your comfort zone (舒适地带) more and more each day.
Follow these suggestions, and begin thinking beyond your "limits" from today. You’ll soon have a life full of interesting and exciting adventures. Who knows, your idea might be the next great idea to change the world.
小题1:Most people can’t be creative geniuses because they _______. | A．don’t have great ideas | | B．don’t want to develop their ideas | | C．are too shy to talk about their ideas | | D．don’t believe they can be |
小题2:The underlined word "it" in the second paragraph means ________.| A．creative thinking | B．the muscle | C．personal style | D．great capacity |
小题3:What do we learn from the passage?| A．No computer can store as much information as human’s brain. | | B．It is not necessary to remember everything around you. | | C．Try something new, as long as you are comfortable with it. | | D．It is harder to exercise the brain than the muscles |
小题4:The passage is intended to tell readers _________.| A．how they can learn from creative geniuses | | B．about ways to develop their creative thinking | | C．about the importance of exercising the muscles | | D．the reasons why they can’t be creative geniuses |

Do you like seahorses? What do you know about them?
The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎动物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?
小题1:We can learn from the passage that seahorses _______.| A．are beautiful, and live on seaweed | | B．are as big as regular horses | | C．live near deep channels | | D．like to be alone |
小题2:The third paragraph tells us that _______.| A．male seahorses lay eggs | | B．seahorses mate in spring or autumn | | C．male seahorses give birth to babies | | D．seahorses mate in warmer waters at night |
小题3:Which of the following protects seahorses from being eaten by their enemies?| A．Their fast speed of swimming. | | B．Their ability to change colours. | | C．Their unique eyes. | | D．Their strong tails. |
小题4:Which of the following can replace the underlined word "grasp"?| A．Eat. | B．Hold. | C．Make. | D．Handle. |

Chinese parents are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter.
However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize, though, is that today’s children lack self-respect and self-confidence.
The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them,tying to fix them ,your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.
小题1:Parents in China according to this passage .| A．are too strict with their children | | B．are too rich to educate their children | | C．have some problems in educating their children correctly | | D．have no problems in educating their children strictly |
小题2:The writer of the passage does not seem to be satisfied with .| A．the parents’ ideas of educating their children | | B．the education system of the school | | C．children’s skills in cooking at home | | D．children’s hobbies in the classroom |
小题3:Doing some cooking at home helps children .| A．learn how to serve their parents | | B．learn how to become strong and fat | | C．get a lot from it and prepare themselves for the future | | D．make their parents believe that they are clever |
小题4:According to the last paragraph we can conclude that .| A．broken radios and television sets are useful | | B．one’s interest and curiosity may be useful for his later life | | C．an engineer must fix many broken radios | | D．a good student should spend much time repairing radios |
