    Do you know what are the World's tallest animals? How do they sleep and drink?

   You may think it's difficult for them to sleep, but they have no such problems because giraffes don't often stop for a snooze(打盹). As they are so tall—males can grow up to 18 feet, giraffes actually have the shortest sleep requirement of all mamma1s哺乳动物), with an average(平均) of half an hour a day. When they sleep, they seldom lie down and sleep for minutes at a time, since it's difficult for them to get up again and it's dangerous in the wild. But the giraffe in the zoo sleeps around 4.6 hours per day, mostly at night. It usually sleeps lying down.

     Drinking Water may cause problems for the animals because their long necks are too short to reach the ground. To drink they must spread their legs in an uncomfortable position, which makes them easily hunted by other animals like Africa's big cats. As a result. thev get most of their water from the plants that they eat. They only need to drink water every few days.

 In the UK, bus journeys are very common. Buses are often convenient（便利的）for the people who live or work in the city center. Passengers can avoid heavy traffic and not have to pay for the parking. However, taking the bus is just a necessary but boring part of life: they get on the bus, pay for it and sit or find a place to stand when it is crowded. Everyone seems sad and bored.

 In Latin America, however, bus trips can be wonderful. For a start, films are showed on the buses between cities for passengers to have fun along the journeys. Local buses do not show films, but drivers usually turn on the radio and it can be great for passengers to listen to songs and get relaxed.

 Even better than films and music are the sights and sounds on the buses. Local buses always go to parts of the town that passengers would not visit by themselves. There passengers can see shops that they have never heard about. And they can also see other cultures of the town from the windows of the buses.

Besides, passengers' luggage（行李）is also interesting. It is common to see a happy dog's head getting out of somebody's bag or a lovely chicken“speaking cheerfully”under somebody's arm. Once on a bus in Peru, a farmer even tied a sheep to the top of the bus. It was quite surprising.

 In all, taking the bus in Latin America is really fun and unforgettable.

    Some students, parents and teachers in Shanghai were surveyed last month. According to the result of the survey, the generation gap (代沟) between students and parents as well as teachers is becoming wider. Here is what they said.

     Voice of the students:

         “Our parents hold too high expectations（期待）which put us under lots of pressure（压力. They care too much about our lives and studies,” one student said.

    “It's impolite that some students' parents read their children's diaries without permission!”one student said angrily.

    “Some of our teachers are so serious that we can't make friends with them at all,” another student said sadly.

    Voice of the parents:

    One mother said, “After school, my daughter usually locks herself into her room and spends lots of time talking with others on the phone. And I can't stand her clothes and hairstyle!”

    “I thought my son was doing very well in his studies. I didn't realize I was being cheated (欺骗)by him until I got a call from his teacher,” said a father.

    Voice of the teachers:

    An English teacher said, “Today, the role of the teacher is to put knowledge into students' brain. The power teachers have kept students away from them.”

    “Some parents pay too much attention to their children's grades. They never create a lively and colorful environment at home,” another teacher said.

    “In the past, teachers and students often played games together or talked with each other. Today, only studies and grades are talked about,” said a teacher.

    Voice of scientists:

    Scientists say that a school should be a place where students can learn not only knowledge, but also how to face failure bravely enough.

    Johnny Smith was a high school student who was good at Maths. He loved his computer. He came home early every day, and then he worked with it till midnight. But Johnny was poor at English indeed. He usually got "F" in his English. One day after school, Johnny joined his computer to the computer in his school office. The school office computer had the grades of all the students; the Maths grades, the science grades, the grades in arts and music and the grades in English. He found his English grade was an "F" again! Johnny changed it from "F" to "A". The next day, Johnny's parents looked at his school report card. They were very happy. "An 'A' in English!" said his father. "You are a very clever boy, Johnny." However, they didn't even know that Johnny was a hacker.

School headmasters and teachers are worried about hackers, so are the police, for some people even take money from bank computer accounts and put it into their own ones. And they never need to leave home to do it! They are called hackers.
