Is there life on Mars? Many people have (36) _____ about this question. Some writers of science-fiction think of people from Mars (37) _____ 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 (38) _____ 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 (39) _____ and other higher (40) _____ forms to be found on Mars.

Astronomers also think that perhaps a small (41) _____ of water vapor could be found on Mars. In 1887, an Italian astronomer, Giovanni Schiaparelli, discovered markings on Mars’ surface.

However, there are (43) _____ who feel that life on mars is not possible. This is because there is little or no (44) _____ 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.

B. Read the passage carefully, then choose the correct answer.

There is one planet that still fascinates and teases scientists mainly because it doesn’t have an atmosphere to 9bscure observation, yet it is not big enough for sufficiently accurate telescopic observation. The fact that it is also very close to the sun also makes it difficult for astronomers.

However, space telescopes have told us a lot more about Mercury. It is rather similar to Earth’s moon and to Mars. There are mountainous areas dotted with craters and large valleys which are uncratered. The moon’s valleys have fewer cracks and the ridges are smoother. Mercury’s valleys are filled with volcanic rocks, similar to on the moon, yet there is no evidence of volcanoes, even extinct ones, on Mercury, as there is on the both Mars and the moon, and of course here on Earth.

So, scientists presume the valleys on Mercury were caused by different things, that is to say not by volcanoes, but by very large meteorites, which also caused the cracks in the terrain and left the ridges rough and uneven. More and better photos of Mercury are needed to prove what are at present at best only hypotheses.

46. What is the topic of this passage?

a. The planet, Mercury b. Observation of planets

c. The Earth’s moon d. Astronomers’ difficulties

47. Why does Mercury still tease scientists?

a. Because it has an atmosphere which obscures observation:

b. Because it is too close to the sun;

c. Because it is too small.

d. Because it is difficult for space probes to get close to.

48. What is true about Mercury but not true about the moon or Mars?

a. The valleys are filled with volcanic rocks. b. There are no volcanoes.

c. The valleys are uncratered d. There are hilly regions.

49. What does the author imply space telescopes can do better than land-based telescopes?

a. Show, the volcanoes on Mercury.

b. Show the meteorites which hit Mercury.

c. Show what caused Mercury’s valleys.

d. Show more of the planet, Mercury.

50. What can we infer from the passage that astronomers still need to get more detailed observation of Mercury?

a. Better and more space telescopes b. More hypotheses.

c. Larger space telescopes d. More ways to prove hypotheses.
