VI, Read the passage and circle the best option A, B, C or D to complete the following questions or
statements:
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.
66. It can be inferred from the passage that the Sun ______.
A. is approximately halfway through its life as a yellow dwarf
B. will continue to be a yellow dwarf for another 10 billion years
C. has been in existence for 10 billion years
D. is rapidly changing in size and brightness
67. What will probably be the first stage of change for the Sun to become a red giant?
A. Its surface will become hotter and shrink.
B. It will throw off huge amounts of gases.
C. Its central part will grow smaller and hotter.
D. Its core will cool off and use less fuel.

VIII. Read and match sentences A-F with gaps 1-5 in the text. There is one extra sentence.
Polar bears live where the ice meets the sea in the Arctic Circle. They are born on land, but they spend most
of their time in the water. (1) ……………………………… However, the polar bear is specially adapted for life
in such a cold place.
The most important adaptation is their fur. A polar bear's fur has both long and short hairs, which means that
it is very thick. This thick fur keeps the bear warm on the land and stops it getting wet when it is swimming.
(2) ……………………………… This means that the bear appears to be white like the snow and ice around it.
The skin under the fur is black. Because of its colour, the skin absorbs the sun's heat and gives the bear
extra warmth.
Under a polar bear's thick fur and black skin is a layer of fat. This layer can be up to 12 cm thick and it
protects the bears from the cold. (3) ……………………………… Polar bears hunt seals for food and these
are difficult to find in the summer when the ice melts.
The shape of a polar bear’s body is also especially designed for the life in the Arctic. (4)
……………………………… All of their body is covered with fur except for the end of their nose. Their round
shape stops the body from losing heat and it helps the bears tolerate the cold.
Polar bears also have fur on the bottoms of their feet, which are enormous. (5) ………………………………
The fur helps the bears walk in the soft snow and also stops them from falling on the ice. The size of their
feet helps them to swim faster, too.
A. Polar bears have a very large body with a small head and very small ears.
B. The hairs are transparent and so the reflect the light from the sun.
C. Sometimes the bears can get too hot, so they jump into the water to cool off.
D. They look like giant snowshoes and they work in the same way.
E. The temperature in the Arctic can be as low as -45ºC in the winter.
F. The bears can also use it for energy when there isn’t anything to eat.

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.
