What will the life be like in 2050? Well, yesterday we did     1     interview with Mr. Black. Mr. Black is a great s    2     in Green City. He said e    3     would be free in 2050. And there would be lots of r    4     in our life. They would work in     5    （工厂）. People would only do     6     （简单的）jobs. They would help people do some h    7    . And people would have longer vacation. People would have more time to take their pets like     8    （蛇）or dogs for a walk. And some of them would go to the m    9     for vacation. Mr. Black said it would take us only a day to f    10     there by rocket. I thought Mr. Black’s predictions were great. I hope they will come true.

Now, it may be difficult to predict the future, but many people believe that we will live on Mars by the year 2100. Our own planet, Earth, is becoming more and more     1    （拥挤的）and polluted. Well, what problems do we need to     2    （解决）before we can get to Mars?

First of all, transport should be much better. At     3    （目前；现在）, humans need to spend several months going to Mars by spaceship. However, by 2100, spaceships may travel at half the speed of light. Then, it would only take us two or three     4    （天；日）to get there! Without     5    （疑问；疑惑）, humans need food, water and air to live. Scientists should develop plants that can be grown on Mars. These plants will     6    （生产；制造）the food, water and air that we need. However, there is no answer for all these problems right now. There is also a problem for us to live in the environment of Mars. Mars has less gravity than Earth. This is dangerous because we can easily jump too     7    （高）and fly slowly away into space there. We will have to wear special shoes to make     8    （我们自己）heavier.

Besides, I     9    （推断；料想）food would not be the same—meals might be in the form of pills and will not be as delicious as they are today. Also, space travel will probably make many people feel very     10    （不舒服的）. In some ways, life on Mars would not be better than that on Earth today.

【推荐3】What will the home of the future look like? A team of architects （建筑师） in Hong Kong say that city homes will be t_______ , as populations continue to grow and space becomes more expensive.

They have designed “spaceflats” that are only 30 square metres in s_______. These flats have small rooms: a living room, a bathroom and a bedroom, as well as a balcony, but everything is c_______planned to make good use of the limited space.

The living room is the main room of the flat. It can be used as an office, a kitchen, even a second bedroom. There is a sofa that can be changed into a bed: The dining table can be changed into a computer desk. And if not needed, both the sofa-bed and the table can be folded away （折叠） and s_______into a small space in the wall. There is a flat-screen TV, which can also serve as a computer monitor. In one of the room, a small cooker, a mictowave oven and a small refrigerator are hidden out of sight.

The o_______ rooms are small but practical. The bathroom contains a toilet and a shower. The double bed in the bedroom can also be a sofa, if necessary. The balcony has enough room for two people to sit and enjoy the view from the block of flats. All the rooms have high ceiling to provide as much storage space as possible, while the flat has l_______ windows to let in plenty of sunlight.

“Spaceflats” are now being tested in a building in Hong Kong. “It's wonderful,” says one citizen. “The flat is so well designed that you feel that there is plenty of space. ”
