任务型阅读。

     阅读下面短文并回答问题(请注意问题后的词数要求)。

    [1] Imagine walking 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 the reality in 13 years if some of the predictions of

100,000 Britons are correct.

   [2] The survey asked the people of the UK how they

pictured the world in 2025.

   [3] 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 labour will be back in power.

    [4] On the world stage 60 per cent think China is set to

become the world's leading superpower, while a third think

Great Britain will be made up of four self-governed countries.

     [5] 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 _                .

    [6] 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.
