Read the below passage on Mars and use the information to write a composition about the possibility of life on the planet .

There has long been speculation concerning about the possibility of life and liquid water on Mars . However , the planet's thin atmosphere prevents water from accumulating for any time over significant portions of the planet . Some evidences of the planet's surface suggest the presence of liquid water at some point in history , but scientists think this water would be too salty or acidic to support life as we know it . Futhermore , fierce solar winds and poor heat transfer across its surface would make sustained life virtually impossible . There is compelling evidence , however , that Mars was once much more habitable to life than it is today .

Start with :

I think that there is no life on Mars . Firstly .......

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 23 to 27.

Is there life on Mars? Many people have (23) ______ about this question. Some writers of science-fiction think of people from Mars as little green creatures. Others imagine 'Martians' as monsters with many eyes.

In studying this planet, astronomers have found that life may be possible on Mars. The first (24) _____ of this is that Mars has seasons, just like Earth. In other words, Earth's seasons, such as spring or summer, occur on Mars too. Because these seasons exist, it may be possible for (25) ____  and other higher life forms to be found on Mars.

         Astronomers also think that perhaps a small (26) ______ of water vapor could be found on Mars. In 1887, an Italian astronomer, Giovanni Schiaparelli, discovered markings on Mars' surface. These markings looked like canals. This finding led astronomers to believe that since water exists on Mars, life forms could exist as well.

However, there are others who feel that life on Mars is not possible. This is because there is little or no trace of oxygen on the planet. In 1965, the Mariner IV capsule managed to take photographs of the planet. It discovered that the only forms of life found are vegetation like fungi and mosses. (27) ______ people remain fascinated by the idea that there could one day be life on Mars.
