The home of the future won't be     1    (complete) different and we will be living in houses and flats just as we do today.     2    (build) in different shapes, no two homes will look the same. People will be able to buy “house kits” containing a basic house structure, with adjustable walls, doors and windows. They will put together the different parts     3     (create) the home they want.

Space holidays will develop in the future, but these holidays won't be for everyone because they are     4     (expensive) than holidays on the earth. Short space trips will develop first, then the space hotels will go around the earth     5    it will be possible to have a longer vacation. By     6    end of the next century, there will be holiday centres on the moon with leisure facilities for families.

According to the laws of physics, the earth is going to    7    ( appear) some time in the future. This isn't going to happen tomorrow but scientists predict that it will happen in five billion years when our sun    8    (explode).     9     a result,we will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it,or we leave and move to another planet. There won't be any other    10    (choose).

Today, we have to use switches for our lights, knobs for our appliances,     1     remote controls for our TVs and air conditioners. In the future, we will be using     2     (advance) technology every day for automatic control of just about everything in our home. The future home will use integrated sensors to tell     3     you leave home each morning, and then go into     4     energy-efficient mode all by itself. You will no longer have to think about     5     (turn) switches on and off yourself. Your home will also learn your daily routine and     6     (prefer), so everything will be ready for you when you get home each evening. Your lights will come     7     the instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already     8     (prepare) for you. All controls will respond to voice commands, so     9     you want to change your routine, you just say aloud what you want and the home system     10     (obey).

Scientists and engineers     1     (prepare) for possible travel into interstellar space, the area in between stars, in the distant future. Experts believe it will likely take many years before the technology and equipment are developed     2     (send) humans to this unexplored area of space. But if it does happen, massive spaceships     3     carry humans on long trips to distant starts.

Two American researchers, Andrew McKenzie from the University of Kansas and Jeffrey Punske of Southern Illinois University, have explored one possible problem with such travel. They considered the possibility     4     changes in human language could develop over time, thus     5     (cause) major communication problems with people on Earth.

Languages naturally change as communities grow more isolated from each other, the researchers noted in the paper. The long isolation of a community could lead to enough differences in language to make     6     impossible for community members back home to understand. The researchers noted that in    7     (add) to new words being used, the language of people traveling on spaceships and living in colonies     8     (experience) many other changes. For example, the sounds of different letters would likely change over time, affecting not only individual words, but the whole grammatioal system.

The researchers say one possible solution to     9     (limit) communication problems would be to include language experts on spaceship crews. Another suggestion is to use sign language as a form of communication. McKenzie added that space travelers might question whether it is even worth trying to learn how to communicate with people on Earth. But he believe there will always be a need, even     10     it is very limited. “You have to learn a little Earth English to send messages back, or to read the instruction manuals and information that came with the ship,” he said.

4 . 阅读下面短文。在空白处填入1个适当的单词或括号内单词的正确形式。

Some scientists think     1     idea of people living on Mars will come true one day. Stephen Hawking believed humans must move into space to survive. “Once we spread out into space and establish     2     (dependent) colonies, our future should be safe,” he said, Robert Zubrin, a rocket scientist, agrees and thinks starting with Mars     3     (make) the most sense. He thinks sending people to Mars will allow us to learn a lot--for example, about the ability of humans to live in a very different environment.

However, scientists will need to terraform Mars for people to be able to live. Terraforming means changing the environment on a planet so that it is similar to Earth's. One of the main goals of terraforming Mars is to warm it up     4     the average temperature there is about -60°C. One idea for warming Mars is to build factories there     5     produce greenhouse gases. This could take many     6     (century). However, it should lead to rainfall and the growth of plants,     7     (result) in more air that people can breathe.

Another big concern for scientists is whether humans can move to Mars and still live     8     (healthy) in mind and body. Not to feel bored, humans on Mars would always need to keep     9     (they) busy with various activities. And the people living together should all be able to get     10     and work together.
