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 43-year-old 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   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 4-year-old male called Tltai that came to Cologne Zoo from an animal park in England.In November it fathered three cubs with a 7-year-old 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 late-night opening of the zoo has been canceled. Cologne Zoo is one of the oldest in Germany.It was founded in 1860 and houses some 10,000 animals consisting of more than 700 different species. According to the police, what was the direct reason for the incident? A) The zoo keeper was a new hand. B) A gate was not closed appropriately. C) The zoo had neglected the secret passage. D) It was very dark when the incident happened.

Car crashes are the top killer of American teenagers.Most of the crashes result from distracted driving not paying attention to the road. Ryan Didone was a fifteen-year-old passenger in a car that hit a tree.He was one of the nation's more than thirty thousand victims of traffic crashes in 2008.Nearly four thousand deaths, about twelve percent, involved drivers aged fifteen to twenty.Ryan's father, Thomas Didone, is a police captain in Montgomery County, Maryland.He said, "It was an inexperienced," immature driver who felt that he was invincible , driving at night with a carload of kids.He was distracted, he was going too fast, and it ended up causing one death and some upsetting experiences and tragedy for the rest of the community." Jim Jennings from the Allstate Insurance Company said "The number one cause of distracted-driving accidents is the mobile phone.Talking on the phone or reaching for it is like drinking four beers and driving.If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't. Reaching for a cell phone when it's going off, you're nine times more likely to get into an accident than normally driving," The insurance industry recently held a safety event  near Washington for teen drivers. At first, nineteen-year-old Kevin.Schumann easily avoided large, inflatable dolls thrown in front of the car to represent children.He also avoided orange cones representing the edge of the road.Then, as part of the test,he started texting. He hit several cones and at least one doll.  Debbie Pickford from the Allstate Insurance Company said, "Teens are especially at risk from distracted driving--and not just because they lack experience on the roads.What we know from research on teen brain development, is that teens don't really have fully developed brains until they are twenty-five years old. You put those two things together and you get a much, much higher risk. A safety event held by insurance industry was meant to   _  . A) attract more teenagers to take part in it B) make more teenagers practice avoiding large barriers C) draw encough attention to teenagers' distracted driving D) encourage more teenagers to pay for insurance protection

How Does Your Body Keep the Same Temperature?        The temperature of your body should always be the same if you are fine, no matter whether the weather is hot or cold. That is why the doctor tests your temperature with a thermometer when you are sick. Normally, your  body temperature is ninety-eight point six degrees Fahrenheit  . If it is higher than that, it is a sure sign that something is wrong with your body.        Your body keeps the same temperature all the time, because it balances   the heat it produces and the heat it gives off. It is always burning up food and producing heat. It can produce heat faster when the body needs or give off heat faster when the body becomes too warm. Let's see how this works.        The heat of your body is given off chiefly through the skin. When you feel cold, your skin is tight and shows "goose flesh". When you feel chilly  , you must jump around to keep warm. Then your muscles begin to work, burn up fuel and produce more heat. It is not pleasant to shiver so you usually prefer warming up by taking exercise, or put on more clothes to keep warm.        When you get warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat and more body heat is used in evaporating the moisture   in your body. In warm weather or warm rooms, you wear less clothing, so that heat can be given off freely. You prefer less exercise because your body is warm enough, and the extra heat produced by taking too much exercise makes you uncomfortable.        Now you see why you feel differently in different kinds of weather. In summer, when it is hot, you feel tired and lazy. You do not care to work or play, but enjoy lying down and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to run and play. From this passage we know that we feel differently in different kinds of weather because   _  . A) our bodies deal with different kinds of weather in different ways to keep the same temperature. B) we feel tired and lazy in summer and lively in winter when we are outside in cold air C) we have different emotions in different kinds of weather D) the body temperature is always changing in different kinds of weather

A large number of women in Western European countries wish that they were born men. The number is said as high as 60% in West Germany. "Women often wish that they had the same chance as men have, and believe it is still men's world," said Dr James Holden, one of the scientists who did the study. Anne Harper has a very good job for an international oil company. She also believes in "Women' s Liberation ". "I don't wish that I were a man," she says, "and I don't think many women do. But I do wish that people would stop looking down upon us women. At work, for example, we often do the work that men do but get paid less. There are still a lot of jobs that are usually the best ones and open only to men. If you're a man, you have a much better chance of leading an exciting life. How many women pilots are there ... or engineers or scientists?" Anne Harper doesn't wish that she were a man because she   _  . A) has got a very good job B) believes in "Women's Liberation" C) does the work that a man can't do D) isn't looked down upon by anyone
