GUATEMALA CITY(Reuters)— A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted(适应)to land millions of years ago, a new study shows.
The Mangrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out.” Taylor told Reuters in neighboring Guatemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)from water onto land,” Wright said.The Mangrove Rivulus is a type of fish that__________.

When a dirty and untidy orange cat showed up in the prison yard，I was one of the first to go out there and pet it．I hadn’t touched a cat or a dog in over 20 years．I spent at least 20 minutes，knelt down behind the kitchen as the cat rolled around，relaxed．What he was expressing outwardly, I was feeling inwardly．It was an amazing bit of grace to feel him under my hand and note that I was reaching a life or another creature with something as simple as my care．
Over the next few days，there were other prisoners responding to the cat．Every yard period，a group of prisoners gathered there．They stood around talking and taking turns petting the cat．These were guys you wouldn’t usually find talking to each other．Several times I saw an officer in the group，not chasing people away, but just watching and seeming to enjoy along with the prisoners．Bowls of milk and water appeared along with bread, wisely placed under the edge of the dustbin to keep the birds from getting it．
The cat was obviously homeless and in pretty bad shape．People said that the cat came to the right place．He's getting treated like a king．This was true．but as 1 watched 1 was also thinking about what the cat was doing for us．There was a lot of talk about what's wrong with prisons in America．We need more programs．We need more psychologists or treatment of various kinds．Some may even talk about making prisons more kind．But I think what we really need is a chance to practise our own kindness．Not receive it，but give it．After more than two decades here，I know kindness is not a value that's encouraged．It's often seen as a weakness．
Instead，the culture encourages keeping your head down，minding your own business，and never letting yourself be weak．
The cat did my heart good to see the effect he had on me and the men here．By simply saying，”I need some help here”，he did something important for us．He needed us．And we needed to be needed．I believe we all do．From the passage，we can learn that the author was．

| B．the American prison culture will be improved |
| C．the author is not content with the prison culture |
| D．caring for others is encouraged in American prisons |
What is the best title for the passage?

In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last year.
As a writer I know about winning contest, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressures of trying to live up to a reputation created by previous victories. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.
A revelation（启示）came last week when I asked her, “Don’t you want to win again?” “No,” she replied, “I just want to tell the story of an angel going to first grade.”
I had just spent weeks correcting her stories as she spontaneously（自发地）told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel starting first trade was quickly “guided” by me into the tale of a little girl with a wild imagination taking her fist music lesson. I had turned her contest into my contest without even realizing it.
Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting（借用）my daughter’s experience.
While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.What do we learn from the first paragraph?
| A．Many children find lots of fun in mindless activities. |
| B．Rebecca is much too occupied to enjoy her leisure time. |
| C．Rebecca collects online materials for her writing. |
| D．Rebecca is different from any other child of her age. |
What was the author's writing experience?
| A．She did not quite live up to her reputation as a writer. |
| B．Her way to success was full of pains and frustrations. |
| C．She was constantly under pressure of writing more. |
| D．Most of her stories had been rejected by publishers. |
Why did Rebecca want to enter this year's writing contest?
| A．She possessed real talent for writing. |
| B．She wanted to win. |
| C．She wanted to share her stories with readers. |
| D．She had won a prize already. |
Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion（混淆） over possible links to the country of the same name, but Sudan officials say there is no connection whatever．
Sudan 1 is a red industrial dye（颜料） that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003．
Since the ban was put in place, EU officials have been trying to remove some food products from the shelves．So far 580 products have been recalled．
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification(澄清) of the origin of the dye’s name．
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye．
"We want to keep an eye on every detail and avoid any misunderstanding there," she said．"Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country．But they told us there was no relationship．"
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week．
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said．"People found the dye in 1883 and gave it the name．Nobody knows the reason, and we cannot give any explanation before we find out．"
Sudan dyes, which include Sudan 1 to 4, are red dyesused for colouring oils, waxes, petrol, and shoe and floor polishes．They are classified as carcinogens by the International Agency for Research on Cancer．What does the underlined word “carcinogenic” mean in paragraph one?
| A．Causing cancer． | B．Having side effect． |
| C．Containing poison． | D．Poisonous． |
How did the Sudan 1 get its name?
| A．The dye is often produced in Sudan． |
| B．The dye has something to do with the country named Sudan． |
| C．Nobody is sure of the origin of the name． |
| D．Many foods produced in Sudan contain the dye． |
We can infer from the passage that．
| A．the Sudan government is paying much attention to the food safety |
| B．Sudan 1 is often used to be added to the food |
| C．people didn’t realize the danger of Sudan1 until 2003 |
| D．many food shops will be closed down |
Which of the following is the best title?

A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami（海啸） warnings just three minutes later. The country has one of the best earthquake early warning systems in the world.
There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes.
There are also concrete(混凝土) sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami.
Costas Synolakis ，a tsunami expert at the University of Southern California in Los Angeles said，"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event."
He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan.
The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas.
Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves.
Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predictedWhere can this passage probably be adapted from?
| A．A magazine on science | B．A fairy Tale |
| C．A scientific fantasy book | D．A newspaper |
Which of the following statements NOT true ?
| A．A terrible earthquake hit the northeastern coast of Japan |
| B．It was also the worst earthquake in Japan |
| C．The 9.0 earthquake was the fourth most powerful earthquake ever recorded in Japan |
| D．Japan's concrete sea walls was unable to handle such high waves. |
According to Costas Synolakis, why did Japan suffer such a loss?
| A．The country has never experienced any event as big as this one over the past 150 years |
| B．Japan has the best earthquake early warning systems in the world. |
| C．There are not concrete sea walls around all of the Japanese coastline |
| D．The government didn’t announce its first tsunami warnings three minutes earlier. |
Scientists have transformed men’s minds into a virtual（虚拟的）woman’s body in an experiment that could throw light upon how humans distinguish themselves form others.
In a study at Barcelona University, men wore a virtual reality headset that allowed them to see and hear the world as a female character. When they looked down, they could even see their new body and clothes.
The “body－swapping” effect was so convincing that the men’s sense of self was transferred into the virtual woman, causing them to react to events in the virtual world they were immersed（沉浸）. “This work opens up another avenue for virtual reality, which is not just to transform your sense of place, but also your sense of self,” said Mel Slater, “If you can temporarily give people the illusion that their bodies are different, then the evidence suggests it also affects their behavior and the way they think. They can have new experiences: a person who is thin can know what it is like to be fat. A man can have an experience of what it’s like to be a woman.”
During the experiment, a “female” approached and hit the face of the character another man was playing. “Their reaction was immediate,” said Slate. “They would take in a quick breath and maybe flinch（退缩）. The more people reported being in the girl’s body, the stronger physical reaction they had.” But in all cases, the feeling was temporary and lasted only as long as the study.
The study shows that our minds have a very fluid picture of our bodies. The research is expected to shed light on the puzzle of how our brain tells the difference between a part of our own body and something else in the wider world. Thus the work might improve the conditions for those who have experienced strokes by placing them in a world that helps them to use their bodies to the full again.How can a man’s mind get into a woman’s body?
| A．by distinguishing themselves from women |
| B．by taking part in an activity actively |
| C．by wearing a special device（设备） |
| D．by transforming his sense of place |
Of the following statements, which we can’t infer from the passage?
| A．Men in the experiment can temporarily have the wrong feeling that they are women. |
| B．When hit, the men in the virtual world will react angrily to it. |
| C．As soon as the experiment is finished, the men will return to the normal state |
| D．Probably, this study can be applied to medical fields and benefit humans. |
What is the author’s intention of writing this passage?
| A．to introduce an interesting and advanced study |
| B．to inform us of the latest development of virtual reality |
| C．to illustrate the importance of virtual reality |
| D．to build up our confidence to fight stroke |
