There is little doubt that house cat first developed naturally from ancient wild cats. The cleverest relative is the America wild cat which still lives in Africa today. This is understandable because the first house cats came from Africa.

    Cats first started to live around people in Egypt about 6,000~7,000 years ago. From Egypt, cats started to move around the world. This is about the same time that Egyptians began storing grain(谷物）in buildings. Scientists used to believe that people tamed cats to catch mice and protect the grain. However, cats don't like to be told what to do! Now, scientists believed that cats followed the mice and learned to accept people. Finally, some of the cats began to grow comfortable around people, these were smaller cats that needed protection. As these cats and people got used to each other, then they moved in together. Around 5,000 years ago, cats started to live with people.

   Soon cats were in Greece, then the Middle East and China. They moved along Egyptian business roads keeping away mice and keeping people around them. After the Romans came to Egypt, they also accepted the cats and brought them to Europe. These cat likely bred(繁殖） with other cats to form the many kinds of house cats we have today.

    Cats are relatively recent house animals. House cats still have a lot in common with their wild relatives. Cats sleep a lot to save energy just like wild cats. They will often get food at night as well. House cats are generally peaceful and friendly, but be careful! If a cat feels it is in danger, it will fight back—just like a wild cat.

    There are world records at the Olympic Games. But what are the word records in animal kingdom?

    The largest and heaviest animal on earth is the blue whale. It weighs between 110 and 120 tons. Its heart is the size of a Mini Cooper, It's got the biggest mouth in the world as well. About 100 people can fit inside it. But it doesn't eat people! In fact, the biggest thing it can eat is the size of an apple.

The giraffe is smaller than the blue whale but it is also a record breaker. It's the tallest living land animal. It's got the longest neck-about 2 metres long, and it's got the longest legs-about 1.8 metres long. Drinking is difficult, but eating from the top of trees is easy! And its tongue is 50 c m long!

    The most dangerous animal in the world isn't a lion or a bear. It's an insect! The mosquitoes (蚊子) that carry malaria kill over 1 million people a year. After that, the most dangerous animal is the venomous snake. They kill 50,000 to 125,000 people a year.

    People have always wanted to know what our future will look like. Go on reading this text, and you will know what will happen in the next fifty years.

    How can we know what the future will look like? To be able to understand the future, you have to know the past, what has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but people are driven by the same basic needs as they were 150 years ago. Will this change in the next 150 years? No.

    What inventions have really made a different in the last 150 years? In the past years, the inventions that have changed most people's everyday life are telephone, radio, television, computer, the car and the internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster cars, trains, etc. In general, people have been working hard in the last 150 years to make inventions that will make the world a better place. Since there is still much to do in the area, this will be important for at least the next 150 years.

    Why do we need to guess the future? Guessing the future is important for two reasons: First, we need to start to think about what kind of future we would like for ourselves and our children. And then we need to know what decisions we need to make today that will give us the best future.

    Shanghai University of Engineering Science has become the first university in China to be covered by a 5G network, the university announced on Tuesday.

    Chinese mobile carriers(运营商) are expected to spend 1.2 trillion yuan（US＄176.5 billion） on 5G by 2025,50 percent more than their total 4G investment (投资), Nomura said yesterday. Carriers including China Mobile, China Telecom and China Unicom, are expected to build over 4.9 million 5G base stations by 2025.

    5G is a" game﹣changing" opportunity for carriers as they can explore new business like smart manufacturing, super high definition video and smart driving, instead of just being a "pipeline" for voice and data services.

    China will supply "temporary "5G licenses in several aimed cities this year. Consumers(消费者) will be able to use the first batch of 5G smart﹣phones and tablet computers in the second half. It's the first time that China's top industry regulator clarified the 5G industry timeline, especially the first appearance of 5G phones.

    But 5G services will become accessible to normal consumers later than expected. More work needs to be done to make the 5G industry fully developed, which won't happen until 2020, said UBS recently. New business projects and organizations, rather than normal consumers, will enjoy 5G services at first. The first batch of 5G services will be available to consumers in about 10 cities only.

    In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.

    Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating (挨打) and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.

    Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged. That is because its computer inside simply doesn't know how to make the machine work after its shape has changed.

    To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine's software. Using this information, the computer can then figure out the machine's shape at any moment.

    The new technology is a big advance in robot-making, scientists say, and it's far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.

    "It has been difficult to design robots that can work well when the environment changes or when it's damaged," says Olaf Sporns of Indiana University in US. "With this work, we are nearer to solving this problem."

What will our life be like in the future? Each family will have a  1  I in the future. You can ask it to do everything  2  you. It will serve you  3  hours a day. The robot will look like a (n)  4 . It can talk with you when you are  5  You won't know whether （是否）it is a human （人类）  6  a robot when you meet it on the street.

People will have  7  time to work and more time to travel. The vehicles （交通工具） in the future will fly freely in the sky because every vehicle will have wings with it. They will 8  you toa lot of places. You can go to  9  during your travels when you feel tired. All vehicles will not be  10  because the robots drive them.
