BERLIN(AP)—A tiger escaped its enclosure at Cologne Zoo in western Germany on Saturday and killed a female keeper before being shot dead by the zoo’s director，police said.
The tiger slipped through a passage between the enclosure and a neighboring storage building，where it fatally attacked the 43yearold keeper，said police spokesman Stefan Kirchner.
“It appears the gate wasn’t properly shut，” Kirchner told the Associated Press.
The zoo was evacuated and a SWAT(特警) team was called in，police said.But before it arrived the zoo’s director managed to kill the tiger by climbing onto the storage building and shooting it through a skylight using a rifle.
Kirchner said it was unlikely that members of the public had witnessed the incident.“This is the darkest day of my life，” the zoo’s director，Theo Pagel，was quoted as saying by Cologne newspaper Express.
The paper said on its website that the Siberian tiger was a 4yearold male called Tltai that came to Cologne Zoo from an animal park in England.In November it fathered three cubs with a 7yearold Siberian tiger called Hanya，according to the zoo’s website.
Police said the zoo reopened after Saturday’s incident，which occurred around noon.However，a planned latenight opening of the zoo has been canceled.
Cologne Zoo is one of the oldest zoos in Germany.It was founded in 1860 and houses some 10,000 animals comprising more than 700 different species.Which of the following can be the best title of the news text?

You are a German living in Berlin. One day you’ re walking down the street, minding your own business, when suddenly a stranger comes up with a smile on his face. After stopping you, he holds a small electronic device (装置) close to his face and speaks slowly into it, saying, in English," Can you tell me where I can buy some sauerkraut?" What should you do? (a) Run away; (b) Call the police; or (c) Listen closely for the device to say in German," Konnen Sie mir bitte sagen, welches sauerkraut haufen kann?"
The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The device is said to be the world’s first portable(便携的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-operated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to translate spoken English into Italian, German, French and Spanish. The product comes with separate cartridges(盒式存储器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Europe soon after the US introduction, with cartridges that translate Italian, German, French and Spanish into English.
The Voice uses a microchip(微型集成电路片) to translate languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language.
The device held by the stranger is probably a kind of________.
| A．a two-way radio | B．language translator |
| C．easily-carried speaker | D．a multi-functioned computer |
What does the last sentence of the first paragraph mean?
| A．Can you tell me where I can buy some sauerkraut? |
| B．Can I ask for some information from the police? |
| C．Would you like to try my device? |
| D．Would you not run away if I ask you where to buy some sauerkraut? |
When the stranger says," Can you tell... sauerkraut?" he is ________.
| A．learning German from his device |
| B．asking you the way to the sauerkraut shop |
| C．making fun of you with his device |
| D．testing his device for fun |
Which of the following is not mentioned in the text?

Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be “like a magic carpet…You could fold it up and put it into your pocket or handbag”. Then he paused: “But you’ll always be limited by the size of the wheels. And so far no one has invented a folding wheel.”
It was a rare — indeed unique — occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout’s Wonderful Bag, a leather case.
Grout’s aim: to solve the problems of carrying a bike on a train. Now doesn’t that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout’s day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn’t do the same with a wheel fitted with a one-piece inflated （充气的） tyre.
So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse （椭圆）. Throughout, the tyre remains inflated.
Will the young Fitzsimons’s folding wheel make it into production? I haven’t the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It’s as silly a concept now as it was 100 years ago: there’s plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than £1,000 that can be knocked down so small that it can be carried on a plane — minus wheels, of course — as hand baggage.
Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie’s imagination? No. But it’s progress.

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding （繁殖） rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical （等级的） societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”When a goby grows to within 5-10% of the size of its larger competitor, it .
| A．faces danger | B．has breeding rights |
| C．eats its competitor | D．leaves the group itself |

Eddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada.
It all started when Graham Broad, a professor at the University of Western Ontario, found McKay’s name in a footnote in a book about university history. McKay was included in a list of university alumni （校友） who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives （档案馆） in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad’s glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. “After looking for him all day, there he was, staring up at me out of the exhibiting case,” said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view.
Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron （中队） as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there’s more to his story. “For a brief time in 1916 he was probably the most famous pilot in the world,” says Broad. “He was credited with downing Oswald Boelcke, the most famous German pilot at the time.” Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane.
McKay’s war records were destroyed during a World War II air bombing on London — an explanation for why he was all but forgotten.
But now, thanks to the efforts of Broad and his students, a marker in McKay’s memory was placed on the university grounds in November 2007. “I found my eyes filling with tears as I read the word ‘deceased’ （阵亡） next to his name,” said Corey Everrett, a student who found a picture of Mckay in his uniform. “This was such a simple example of the fact that he had been a student just like us, but instead of finishing his time at Western, he chose to fight and die for his country.”What made Professor Broad continue his search for more information on McKay?
| A．A uniform of McKay. | B．A footnote about McKay. |
| C．A book on McKay. | D．A picture of McKay. |
What did the students find out about McKay?

| C．He died in the Second World War. |
| D．He was downed by the pilot Boelcke. |
