Mercury is the smallest member of the sun's family. It is only 3.100 miles across. It is also the sun's swiftest planet. Its yearly journey round the sun is only 85 days.

Mercury always keeps one side towards the sun. On this side it is always day, on the other side always night. We only see the lighted side.

Mercury appears to us like a yellowish orange star. The nearest planet to the sun, it is always seen near the sun, either just before sunrise or soon after sunset. People sometimes call mercury the morning star or evening star.

Mercury is half the size of the earth. Because it is much lighter, it has much less gravity. If you can visit Mercury in a spaceship, you will find it a strange world. Its low gravity makes you feel very light. If your weight on earth is 100 pounds, your weight on Mercury is only 27 pounds. Looking at the sun from Mercury, you can see that it's much more brilliant than it is seen from the earth. And the yellow centre of the sun appears three times bigger from Mercury.

On its lighted side, Mercury's temperature is about 300 degrees centigrate. But the dark side is extremely cold, but 150 degrees below zero so mercury is probably the coldest as well as the hottest of the planets.

21. A. Mercury is .......

A. the sun's fastest planet B. the coldest planet

C. the hottest planet D. all are correct

22. We cannot see the dark side of Mercury because .......

A. it moves very fast.

B. it always appears just before sunrise or soon after sunset.

C. it always keeps one side towards the sun.

D. it is too far for us to see.

23. When can we see Mercury? - We can see it ......

A. just before the sunset

B. just before sunrise

C. after the sunset

D. both A and C are correct

24. Why do we weigh much on the earth than on Mercury? - Because .......

A. Mercury is nearer to the sun. B. Mercury has got less gravity than the earth.

C. Mercury is much hotter. D. none are correct.

25. Why does the sun look bigger when it is seen from Mercury?

- Because .......

A. Mercury is the smallest planet of the sun.

B. Mercury is nearer to the sun.

C. Mercury is a light planet.

D. It only takes Mercury 88 days to move round the sun.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.

   Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist- skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere else in the word. The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun-baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

Question: Man can hardly understand why many animals live their whole life in the desert, as

A. water is an essential part of his existence

B. very few large animals are found in the desert

C. sources of flowing water are rare in a desert

D. water composes the greater part of the tissues of living things

Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements feltno more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.

Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements feltno more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.

The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun. Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide iscorrespondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times, the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the month.

Choose A, B, C, or D

1. The main point of the first paragraph is ...

A. The wave created by ocean currents are very large

B. Despite the strength of the wind, it only moves surface water

C. Deep ocean water is seldom affected by forces that move water

D. The tides are the most powerful force to affect the movement of ocean water

2. The word "In reality" in the third sentence of the second paragraph is closest in meaning to

A. Surprisingly

B. Actually

C. Characteristically

D. Similarly

3. According to the passage, the most vital factor in recognizing how much gravitational effect one object in space has on the tides is

A. Size

B. Distance

C. Temperature

D. Density

A. The sun counteracts the moon's gravitational attraction

B. The moon is full

C. The moon is farthest from the sun

D. Waves created by the wind combine with the moon's gravitational attraction
