Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you’re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there’s going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they’ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this.

The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It’s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven’t expected launch costs to come down far enough to make them possible.

    Lots of people who’ve been to space have described vividly what it’s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don’t need to sleep much living in zero gravity, so you’ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.

    Of course all good things have come to an end. Unfortunately, And so after a few days you’ll find yourself heading back enough you’ll be much more expert at exercising in zero gravity than you were when you arrived. You’ll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel.

When traveling in space, most people would like to stay in orbit for a few days because _______.

A. It is expensive to travel in space 

B. they would find the possible life in other star systems

C. they could enjoy the luxury of space hotels

D. they want to realise the full potential of tourism

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品)  of technological developments in the space, the chance to save ourselves might not exist.

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

1.Why does the author mention the questions in Paragraph1?

A. To express his doubts

B. To compare different ideas.

C. To introduce points for discussion

D. To describe the conditions on Earth.

2.What is the reason for exploring space based on Paragraph2?

A. Humans are nature-born to do so.

B. Humans have the tendency to fight.

C. Humans may find new sources of food.

D. Humans don’t like to stay in the same place.

3. What makes it possible for humans to live on other planets?

A. Our genetic makeup.

B. Resources on the earth..

C. The adaptive ability of humans.

D. By-products in space exploration.

The home of the future won’t be completely different and we will be living in houses and flats just as we do today．But people will want to shape their homes to match their dreams．No two homes will be the same．People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows．They will put together the different parts to create the home they want．

Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today．

Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centres on the moon with leisure facilities for families．

Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reuseable paper．

The laws of physics tell us that the earth is going to disappear 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 explodes (爆炸)．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 choice.

1.Homes of the future will ________．

A．be completely different from those of today

B．be very similar to our homes

C．all be different from one another

D．be movable as you want

2.Space trips and staying in space hotels will ________．

A．become a very common way to spend a holiday

B．be the best holiday option for families

C．attract a lot of people

D．still only be for very rich people

3.E-paper will replace traditional paper because ________．

A．we will use it again

C．it will be cheaper to produce

D．it will be convenient to carry

4.We will have move to another planet ________．

A．if we want to save the human race

B．when the sun explodes

C．when the earth disappears

D．when the earth is too crowded to fill people on
