阅读下面短文并回答问题,然后将答案写在横线上(请注意问题后的词数要求)。

     Imagine waking up to a world where China is the world's leading superpower, astronauts are busy

walking on Mars and a brand new political party is ruling the UK? Well, this could be reality in 14 years if some of the predictions of 100,000 Britons are correct.

     The survey asked the people of the UK how they pictured the world in 2025.

     Nearly half believe Prince William will be crowned King of England instead of Prince Charles although one in six think the monarchy (君主制度) will have been abolished. A quarter of those surveyed believe

a new party will form the government in 2025 although the same number of people think that Labor will

be back in power.

     On the world stage 60 percent think China is set to become the world's leading superpower, while 30

percent of people think Great Britain will be made up of four selfgoverned countries.

     Meanwhile technology will have come on in leaps and bounds. Four percent are optimistic that there

will be a permanent human base on Mars while one in ten expect a colony of humans to be living in space. More than half questioned in the MSN study predict people will watch all their favorite shows via TV sets hooked up to the Internet. Two thirds believe cosmetic surgery(整容手术) will have become common

and one in six think we will look after our own health using computers rather than________.

     But at least we can amuse ourselves with the daily comings and goings of pop singers and reality stars, as more than half think that "celebrity(明星)"will be a registered profession.
