He spent seven days in the wind and snow,      .

She is no longer       .

North-east of the province       , where the famous writer was born.

To be honest, his bad temper is      .

We don't know       that day.

    This is a funny story about a travel to the future. Li Qiang couldn't believe he had travelled to the year AD 3008       a time capsule. He had to remind himself       (constant) that it was true. Because this was his first time trip, he was so worried and unsettled at first       he suffered from "time lag". The moment he got there, he found the new surroundings were difficult       (tolerate). Besides, he was hit by a lack of fresh air. His guide, Wang Ping, who was very understanding, gave him a mask and hurried him to a small room to rest, which helped him feel       (good) in no time. After that, he flew above the ground in a hovering carriage       (drive) by a computer. On the way Li Qiang lost sight of Wang Ping when they reached       looked like a market because too many carriages flew by in all       (direction). Arriving home, he       (show) into a large, bright clean room with a wall of trees. After       (eat) something, he fell fast asleep in the bed that was produced from the floor.

    We don't know how different our future will be in the year 2050. We can only try to imagine it.

    At first we think about the human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won't be as important as they are today—we will feel a little lonely.

    Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

    Spending holiday will also be completely different. Travelling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.

    We could expect that the faster technological progress would lead to a more polluted environment. But it isn't true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.

    Although we can't predict the exact changes which will be made in the world, we often think about them. We worry about our and our children's future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen.

    As Artificial Intelligence(AI) becomes increasingly sophisticated(复杂的), there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science Professor Stuart Russell, if we figure out how to turn human values into a programmable code.

    Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language.

    For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell.

    Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

    It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

    Robots could also learn values from drawing patterns from large sets of data on human behaviour. They are dangerous only if programmers are careless.

    The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboos(禁忌).

    One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.

    If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.

    The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.

    Many automobile makers present their newest designs at car shows around the world. Many designers seek to create the car of the future. One device that is popular among car manufacturers(生产商) is an autopilot. Autopilot permits a car to drive itself without human control.

    A recent car show in Geneva, Switzerland also presented other possible designs, including cars manufactured in 3-D printers.

    Rinspeed is a Swiss design company. It showed a vehicle based on the US electric car Tesla Model S, but the Rinspeed car includes a large television and an espresso coffee maker.

    Frank Rinderknecht is the CEO of Rinspeed. He says he does not want to just sit and watch the steering wheel(方向盘) turn as he rides in a car with autopilot.

    "I want to ride; I want to sleep, relax, watch movies, news, anything else. So that's the vision which we have. One day on the boring motorway traffic, you just do anything which makes your life better," said Rinderknecht.

    One of the most interesting ideas presented at the show is a car built on a 3-D printer. The German engineering firm EDAG designed the car. The body of the vehicle called "Genesis" is printed in one piece from a material called thermoplastic(热塑性塑料).

    Christoph Horvath is spokesman for EDAG.

    "To create a car without the use of any tool. This would be a real revolution for the industry," said Horvath.

    EDAG says it based its design on a turtle shell. The company says the design provides the right amount of strength and firmness.

    Other automakers did not look so far into the future. Czech automaker Skoda presented its "Vision C" model vehicle. The car has an environmentally friendly natural gas engine.

    Jo Davidson is a company spokeswoman. She says the car releases very low levels of the pollutant gas CO₂. Ms Davidson says the "Vision C" plans to be launched in two years.

    One day, a father and his son were walking with their horse. An old man saw them and said, "You       (suppose) to ride a horse, not to walk it!" The father then put his son on the horse.

    Soon they passed a group of people,       said, "That's a lazy boy! He gets to ride the horse while his father walks." The father decided to take his son off and get on the horse himself.       they kept going, they came upon two       (passer-by). One said, "You are a       (self) man! Your son has to walk while you get to ride!" The man then reached down and put his son on the horse with him.      a while, they entered a town. Everyone started to laugh at them,      (say), "You are too heavy for that horse!" The father and his son didn't know what       (do).

    Finally, they decided to carry the horse. When they came to a bridge, the horse       (fall) to the water. "If you try to please       ," the father told his son, "in the end, you will please no one." Then they went home.
