1. Fill in each blank space with one appropriate from the box.

manned     seriously    affected     space     radiation     groundless

weightlessness     harmless     journey    flown     appeared     effects

Before man had (31) flown in space it was thought that his physical and mental capabilities might be (32) affected by long periods of (33) weightlessness,and that he might be endangered by high levels of (34) radiation. Yuri Gagariri's first (35) space flight in April 1961 showed that man could live in space and, although this (36) journey only lasted for 108 minutes, it gave encouragement to those interested in the future of (37) manned space flight. In fact most of the early fears about man's health in space have proved (38) groundless, and although several odd medical (39) effects have been observed, none has (40) seriously affected man's ability for useful work.

2. Read the passage carefully, then decide whether the following statements are true (1) or false IF).

Throughout history there have been many great explorers. Have you, for example, heard of Marco Polo, the famous Italian traveler? He was the first European to travel to China. He arrived in China in the late 13th century. About 200 years later, Christopher Columbus sailed from Spain by ship. He was looking for a new way to reach India. However, as you probably know, he didn't reach India. He landed in America. Five hundred years after Columbus in the' 1930s a famous explorer named Richard Byrd was one of the first persons to fly over both the North and the South Poles. Today we continue to explore this world and are studying to explore other worlds, too. In the 1930s Russian and American scientists sent many unmanned spacecraft to the moon. These spacecraft sent back very valuable information about the moon. Then on July 16th 1969 the first manned spaceship to the moon left earth. On that day Apollo 11 blasted off with three American astronauts on board. Four days after blast-off, two of these astronauts landed on the moon. They later explored the surface of the moon. About two days after landing on the moon, they started back to the earth. They arrived safely back on earth a few days later. Today we are sending unmanned spacecraft to other planets. In the future, we might walk on Mars or Venus the way we did on the moon. We might even travel to other galaxies. Who knows? One thing we know for sure is that we will continue to explore this world and other worlds, too.

1. READING

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. These markings looked like canals. This finding (42) _____ astronomers to believe that since water exists on Mars, life forms could exist as well.

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.

2. 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.

14. What is the topic of this passage?

a. The planet, Mercury    b. Observation of planets

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

15. 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.

16. 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.

17. 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.

18. 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.

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. These markings looked like canals. This finding (42) _____ astronomers to believe that since water exists on Mars, life forms could exist as well.

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.

1. 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.

a. Show, the volcanoes on Mercury.

b. Show the meteorites which hit Mercury.
