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__________.
| A．like eating nuts |
| B．prefers living in dry places |
| C．is the longest living fish on earth |
| D．can stay alive for two months out of water |
Who will write up a report on Mangrove Rivulus?
| A．Patricia Wright | B．Researchers in Guatemala |
| C．Scientists from Belize | D．Scott Taylor |
According to the text, lungfish can__________.
| A．breathe through its skin |
| B．move freely on dry land |
| C．remain alive out of water |
| D．be as active on land as in waster |
What can we say about the discovery of Mangrove Rivulus?
| A．It was made quite by accident |
| B．It was based on a lab test of sea life |
| C．It was supported by an American magazine |
| D．It was helped by Patricia Wright |
When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes－the TV cameramen－have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.
Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN－have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.
These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.
TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.
By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.TV news agencies turn to freelance cameramen in order to .
| A．save expense and avoid risks |
| B．get free and useful pictures |
| C．get first-hand information and pictures |
| D．satisfy the greed of the freelance cameramen |
We can infer from the passage that the freelance cameramen .
| A．have to take a lot of risks in the course of work |
| B．are tied to many TV news agencies |
| C．have better skills than other cameramen |
| D．need to contract out risks of work for TV companies |
According to this passage, some major broadcasters and TV news agencies .
A. have employed enough cameramen
B. are not willing to employ many cameramen
C. are very mean to freelancers
C. are responsible for the freelancer if he is injuredThe author of this passage shows his the freelance cameramen.
| A．sympathy to | B．respect for | C．anger to | D．admiration to |

When I was young, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never shouted at us for playing in his yard. I remembered him as a neighbor who was nicer than anyone else in the neighborhood.
When Dr. Gibbs was happy, he was planting trees. And his life’s goal was to make it a forest.
Dr. Gibbs had some interesting theories about planting. He talked about trees that weren’t watered would grow deep roots in search of water. So he never watered his trees. He planted an oak (橡树) and, instead of watering it every morning, he beat it with the rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died a couple of years. Every now and again, I walk by his house and look at the trees that he planted twenty-five years ago. They’re very strong now.
I planted a couple of trees a few years later. I watered them regularly and took good care of them. Whenever a cold wind blows, they shake their leaves and branches.
The funny thing about those trees of Dr. Gibbs was that difficulty seemed to help them in ways comfort and ease never could.What was Dr. Gibbs’ life goal?
| A．To build a forest. | B．To save more lives. |
| C．To make a lot of money. | D．To study plants. |
One of Dr. Gibbs’ theories about planting was that ______.
| A．he often talked to the trees | B．he kicked the trees heavily |

What does the writer mainly want to tell us?
| A．Trees are not as weak as we think. |
| B．We should listen to others’ advice. |
| C．Difficulty is necessary for growth. |
| D．Planting trees is good for the environment. |
Streit was an experienced safecracker who never used force —either against people or safes (保险箱). He was a real artist of his trade and it took him only 19 minutes to open the most difficult safe he had ever encountered. In about 10 years, helped by his brother Stefan and two friends, he took about $330,000 —from the safes of 28 banks in Austria. On his last job, early in 1999, he left the safe door open and $80,000 behind. With the money ws a note, "We don’t need all that much." A witness (目击者) recognized his car and Streit was caught by the police. Then he was sent to Austria’s Stein Prison to serve a six-year sentence. He boasted (吹嘘) at his trial that he would continue breaking the law, "I am a thief and I shall use every opportunity." Despite the warn-ing, prison officials moved Streit to the prison’s blacksmith (铁匠) shop. One day during the week before Christmas, Streit disappeared. Searchers found all his doors were well locked. Streit had managed to make a set of keys and let himself out. Not to freedom, though. After crossing into Bavaria, Streit attracted the suspicion (怀疑) of German customs police on purpose and got himself arrested. "I want to be in a German prison,"he explained to the surprised police. "As German courts give much milder (温和的) sentences for crimes like mine and will reduce the time I would otherwise have served in Stein Prison." In prison, Streit persuaded his keepers to let him make a Christmas Eve telephone call to his former keeper, Karl Schreiner of Stein Prison. "I’m sorry if I caused trouble. I didn’t want to embarrass anybody by escaping. Conditions weren’t that bad. In fact the food was better than it is here."The underlined word "safecracker" in the first paragraph means "_________".
