Life in the past and Life in the present

Over the last century, there have been many significant changes in the way we live. Obviously, it is hard to compare the life of the ancient people and the life of the people of the twenty first century because so many changes have occured. However, even the changes that have taken place over the last ten years are amazing.

To start with, people were not able to travel such long distances in such short period of time. The planes were not that popular then because they used to be a very expensive means of transport. Nowadays, we have become very mobile. We have fast and comfortable cars and more and more people also travels by plane. Moreover, in the past people had to work much harder as they did not have tools which made their work easier. Today, most of the difficult and dangerous work is done by computers and other machines. In the past the conditions of living were not as comfortable as they are now. There were not bathrooms and running water in many houses, besides many people could not afford household appliances like fridge, TV set or vacuum cleaner because they used to be luxurious goods. Another difference between living now and in the past is the fact that nowadays the access to education is much easier. In the past, there were fewer schools and the quality of the education they provided was much poorer. Besides, nowadays it is much easier to find the educational materials that you need thanks to the Internet. Another difference is that in the past there were not that many sources of entertainment. Therefore people used to spend more time with their friends.

All things considering, it is an obvious conclusion that life has changed significantly in the last couple of years. It is definitely much easier now however, it is not easy to decide whether it is also better. The scientific achievements and technological progress are amazing. We still create new inventions which simplify our lives. On the other hand, however, life now is much faster and more busy than it used to be in the past. Moreover, it has also become more dangerous. The standard of living has definitely improved but it can be discussed whether the quality of our lives is also better.

1. Life nowadays is the same as life of our ancestors.

2. Technology has made our lives easier.

4. Public schools allowed females and males to be educated in the same schools.

5. We can use the internet to communicate with people around the world.

* Answer Question:

1. Is life today faster or slower than life in the past?

2. What has happend to the standard of living?

3. What makes it easy to access information?

4. Who or what does some difficult jobs for us?

Life in the Universe

    Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such a life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extraterrestrial life forms might be like.

What sorts of planets are most likely to develop life? Most scientists likely to agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble the continuous movement ands transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important.

The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and burn out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problems. First of all, planets is their habitable zones will be so close to the stars that they will be “tidally blocked”- that is one side of the planet will always face the star in perpetual daylight with the other side in perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. 
Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. 
Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas gains, such as Saturn and Jupiter, in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth

It can be inferred from the paragraph 3 that ______.

A. the Earth is in the sun’s habitable zone

B. the Earth is tidally locked to the sun.

C. the sun varies in its luminosity.

D. variations in luminosity help life to develop
