Tigers are among the most admired and most feared animals in the world . When we think of a tiger, we think of danger. We think of the big teeth and large feet of it. We also think of beauty. The tiger is a hunter that hunts alone. In fact , tigers are probably better than any other land mammal at catching large animals without help. Even so, the life of this big-game hunter isn't easy. Finding food can be difficult, especially for a tiger that is old or weak. Most of the animals it tries to attack get away. A tiger sometimes goes weeks without eating. When that happens, it may hunt animals that can be dangerous even for a tiger. When they are in a bad situation, some tigers may even attack humans. But in fact, tigers kill very few people each year. Most tigers run away when they see people. What tigers have done to people can't compare to what people have done to tigers. Over the last 200 years, we have almost killed tigers in the wild . Today, the tiger is one of the most endangered animals on Earth. A tiger may live 20 years or more, if it is not disturbed by humans. Female tigers usually live longer than male tigers, because the males live more dangerously. It isn't easy for people to tell a male from a female unless the female happens to be with her babies.Only females take care of the young. The big difference between males and females is size. Male tigers are much bigger. Tigers are big eaters. In a single year, one tiger must eat about 70 deer or other large animals. That is one reason why tigers hunt alone. If they lived in big groups, they could never find enough animals to feed them all. The easiest way to tell a male tiger from a female one is by looking at their _ A) size B) running speed C) way of hunting D) claws

More often than not, the person sitting next to you on a plane or sleeping in the next hotel room has paid more or less than you did for the same services. Each day, airlines give more than several hundred fares for flights between the same two cities and hotels charge different rates for the same room. So how do you find the best rates? Here are some tips: ^ Sign up for fare special e-mails. When airlines get into a fare war, the cost of a plane ticket can fall overnight and the discounted fare may be sold out by noon the next day. Get on the mailing list of airlines and other travel Web sites so you can be told immediately if fares drop. ^ Buy your tickets at least 21 days in advance. There are usually four different timetables for advance tickets: 21-day, 14-day, 7-day, and 3-day. The further in advance you book your flight, the lower the fare you will find. ^ Consider another airport. Find out about all the airports that are near your destination city. You might be able to fly into a smaller airport or neighboring city at a much lower rate. ^ Stay over a Saturday night. Airlines give the highest fares to business travelers, who fly during the week and spend their weekends at home. If you plan to leave for your trip on a Wednesday and return on Saturday, your fare would be a lot higher than you stay until Sunday morning. ^ Fly on Tuesdays, Wednesdays, and Saturdays. Some airlines offer cheaper fares on different days of the week. Generally, it's the cheapest to fly on Tuesday, Wednesday, and Saturday. Remember, though, that a Saturday stay is necessary to receive the lowest rate. ^ Pick a flight with plenty of open seats. Seats in a flight are divided into "classes", and each class has its own price. Since the cheapest classes sell first, the fewer seats that are left on a plane, the more expensive they are. If you are a business traveler, you want to save money. What should you do? A) Ask the manager of the air company to cut down the price of the ticket. B) You'd better stay one more night and not go home on Saturday C) You'd better fly during the week and spend your weekends at home. D) Never go abroad on business during the weekend alone.

Ques: Almost no young people today know who the cartoon character Oswald the Rabbit is, but they certainly recognize his successor, Bugs Bunny. Oswald, Bugs, and hundreds of other characters were created by Walt Disney, perhaps the most famous cartoonist in history. Born in prefix = st1 /Chicagoin 1901, Walt Disney always wanted to be an artist. After returning from World War I, in which he drove an ambulance, Disney worked as a commercial artist. He enjoyed drawing cartoons more than anything else, and decided to try his hand at a technology that was new at the time, moving pictures. In the 1920's, he produced several films where he made cartoon characters move as if by magic. The technique Disney used was painstaking. He made hundreds or even thousands of repeated drawings of the same character. In each drawing, the character was changed just a bit. A film was taken of the series of drawings, and when it was shown, the characters appeared to move. The process, called animation, is still used today, although computers have made the process much easier. In 1928, Disney created his most famous character, Mortimer Mouse, who we know today as Mickey. The mouse starred in a cartoon called Steamboat Willie, which was unusual because it involved the use of a sound track. Within the next few years, Disney invented many of his other characters. The list of Disney's animation successes is long and memorable. It includes Pinocchio, Dumbo, Bambi, Cinderella, and Peter Pan. Perhaps his most remarkable animated film is Snow White and the Seven Dwarfs. Created in 1937, it was an immediate success. Today, more than fifty years later, it is still one of the most popular films for children. Which of these words best describes Walt Disney? A) Creative. B) Athletic. C) Exciting. D) Quiet.

Have you ever walked to the shops, only to find when you get there that you've completely forgotten what you go for? Or have you struggled to remember the name of an old friend? For years, we've accepted that a forgetful brain is as much a part of aging as wrinkles and grey hair. But now a new book suggests we've got _ all wrong. According to The Secret Life Of The Grown-up Brain, by science writer, Barbara Strauch, our brains actually get better with age. In fact, she argues many new studies have found that the brain hits its peak between our 40s and 60s --much later than previously thought. Furthermore, not losing many brain cells as we age, we preserve them, and even produce new ones well into middle age. For years it's been accepted that the brain, much like the body, got worse with age. But the longest, largest study into what happens to people as they age suggests otherwise. This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that, on average, they performed better in cognitive tests in their late 40s and 50s than they had in their 20s. Specifically, older people did better in tests of vocabulary, spatial orientation skills, verbal memory (how many words you can remember) and problem solving. Where they were weaker was in numeracy (how quickly one can multiply, add, subtract and divide) and the speed at which they could move. However, with harder tasks, such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are going to come up with scientific evidence that we do get wiser with age. Science writer, Barbara Strauch, believes that _ . A) our brains are wisest between our 40s and 60s. B) we lose many brain cells as we age. C) our brains are at their worst after our 60s. D) people are wiser now than years ago.
