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?

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.

IV. Read the following text and answer the questions by choosing the option A, B, C or D.

        Mercury is the smallest planet in our solar system. It's just a little bigger than Earth's moon. It is the closest planet to the sun, but it's actually not the hottest. Venus is hotter.

        Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. It has a thin atmosphere, and it doesn't have any moons. Mercury likes to keep things simple.

        This small planet spins around slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. A year on Mercury goes by fast. Because it's the closest planet to the sun, it doesn't take very long to go all the way around. It completes one revolution around the sun in just 88 Earth days. If you lived on Mercury, you'd have a birthday every three month!

        A day on Mercury is not like a day here on Earth. For us, the sun rises and sets each and every day. Because Mercury has a slow spin and short year, it takes a long time for the sun to rise and set there. Mercury only has one sunrise every 180 Earth days! Isn't that weird?

VI.Read the passage carefully, tlien decide whot hen the following,statement are true T) or false (F)
There are nine planets in our solar system. These planets each have their atmosphere and environmental conditions. Scientists have been trying to research other planets to see if it is possible for life to exist on the other eight own bodies in space.
Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.
Many scientists also believe that our solar system is not alone in the uni- with us. It is difficult to know if there is life present elaewhere in the universe. for many years to come. yerse. Many believe there are several other systems that share the uhiverse .The universe is a complex structure of space that may continue to be a mysterey for many years to come
32. There are nine planets in our solar system, besides Earth.
33. It is difficult to study the planet Mercury because it is very close to the sun.
34. We don't know much about Pluto even though we can see it up close
35. Pluto may not be a planet, according to some scientists.
36. Scientists have got enough information about the universe

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

    The Sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its center that convert hydrogen to helium. The Sun has existed in its present state for about four billion six hundred million years and is thousands of times larger than the Earth.

    By studying other stars, astronomers can predict what the rest of the Sun’s life will be like. About five billion years from now, the core of the Sun will shrink and become hotter. The surface temperature will fall. The higher temperature of the center will increase the rate of thermonuclear reactions. The outer regions of the Sun will expand approximately 35 million miles, about the distance to Mercury, which is the closest planet to the Sun. The Sun will then be a red giant star. Temperatures on the Earth will become too high for life to exist.

    Once the Sun has used up its thermonuclear energy as a red giant, it will begin to shrink. After it shrinks to the size of the Earth, it will become a white dwarf star. The Sun may throw off huge amounts of gases in violent eruptions called nova explosions as it changes from a red giant to a white dwarf.

          After billions of years as a white dwarf, the Sun will have used up all its fuel and will have lost its heat. Such a star is called a black dwarf. After the Sun has become a black dwarf, the Earth will be dark and cold. If any atmosphere remains there, it will have frozen over the Earth’s surface.

It can be inferred from the passage that the Sun ___.

A. has been in existence for 10 billion years

B. is approximately halfway through its life as a yellow dwarf

C. will continue to be a yellow dwarf for another 10 billion years

D. is rapidly changing in size and brightness
