What can you imagine the life 100 years from now? In fact, no one can know it from now, but scientists studying the evolution of the society, human life and the world in general make such kind of predictions based on scientific data. According to their publications in scientific journals, let’s see how the world might look like in 100 years from now.

Embedded computers

According to predictions by Ian Pearson and Patrick Tucker, by 2050 the human body will be embedded2 with computers, at least in a big part of the population, and by 2075 most of the citizens of the developed world will have some kind of chips built in their brains to make them work faster and share thoughts in the form of computer data.

Superhuman geniuses

Developments in genetic engineering will create human geniuses who will live forever. Does it sound unbelievable? It is sure that there will be a way to influence the brain to increase the intelligence level and with the help of genetics it will be possible to maintain human body for many years.

Global currency

According to futurists, it is very likely that a global electronic currency will be created. They say that the local and national currencies will be few until mid-century and will gradually disappear, let alone metal currencies.

Three world languages

There will be only three world languages: English, Spanish and Chinese. Other languages will have no chance to survive through time. Futurists say that many minority languages are already extinct and the fac t that all educated people in the world speak at least one of these languages will help in this way.

Oceans as a food source

It is one of the most “confident” future devel opments, according to scientists, because if the world population continues growing at the same rate, it will reach ten billion. So the food will not be enough. Thus the oceans will be used to raise fish and to provide populations with fresh water taken from the sea plants.

Journeys into space

Most futurists agree on this and believe that some kind of tourist attractions will be created in space, although they will be affordable only for wealthy people.

1.Why will there be only English, Spanish and Chinese according to the passage?

A. Because other languages won’t be important.

B. Because people who speak minority languages won’t be willing to speak their native languages.

C. Because more and more educated people speak English, Spanish and Chinese, which will cause many minority languages extinct

D. Because in the whole world all the people must not speak other languages.

2.What currency can we use to buy goods in the future from the passage?

A. local currency　　 B. metal currency

C. national currency　　 D. global electronic currency

3.The main idea about the passage is about        .

A. what the people look like 100 years  from now .

B. what the life of people is like 100 years from now.

C. what the environment is like 100 years from now.
