If you woke up 20 years from now in 2042, what would be different? Here are some ideas     1    (base) on numbers that don’t require crystal ball. About 70% of the world population is expected to live in urban areas by 2050. That means most cities are going to need more infrastructure. Roads, public transportation and waste management     2    (upgrade). And we’ll be older. We are likely to live until 82.4 years old, compared with the current life expectancy of 79.1 years. That’s a good thing     3     health care companies. But living three extra years is going to be more expensive,     4     will have implications for both working and saving.

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).
