6. ________ 7. ________ 8. ________ 9. ________ <strong>10</strong>. ________<br />

IV. You are going to read an article about the galaxy. Ten sentences or phrases have been<br />

removed from the article. Choose from the sentences or phrases A- J the one which fits each gap<br />

(1-<strong>10</strong>). (1 point)<br />

………………………… (1) …………………………. A galaxy is a giant family of many millions<br />

of stars, and it is held together by its own gravitational field. ………………………… (2)<br />

………………………….<br />

There are three main types of galaxy: ………………… (3) ………………. The Milky Way is a<br />

spiral galaxy: ………………………… (4) …………………………. About one-quarter of all galaxies<br />

have <strong>thi</strong>s shape. Spiral galaxies are well supplied with the interstellar gas in which new stars form; as<br />

the rotating spiral pattern sweeps around the galaxy it compresses gas and dust, triggering the<br />

formation of bright young stars in its arms. ………………………… (5) ………………………….<br />

Most of their member stars are very old and since ellipticals are devoid of interstellar gas, no new stars<br />

are forming in them.<br />

The biggest and brightest galaxies in the universe are ellipticals with masses of about <strong>10</strong>13 times that<br />

of the Sun; these giants may frequently be sources of strong radio emission, ……………(6)<br />

……………. About two-<strong>thi</strong>rds of all galaxies are elliptical. Irregular galaxies comprise about one-tenth<br />

of all galaxies and they come in many subclasses.<br />

Measurement in space is quite different from measurement on Earth. Some terrestrial distances can<br />

be expressed as intervals of time: ………………………… (7) …………………………, for example.<br />

By comparison with these familiar yardsticks, the distances to the galaxies are incomprehensibly large,<br />

………………… (8) …………………, in <strong>thi</strong>s case the distance that light travels in one year. On such a<br />

scale the nearest giant spiral galaxy……………………(9) ………………, is two million light years<br />

away. The most distant luminous objects seen by telescopes are probably ten thousand million light<br />

years away. ………………………… (<strong>10</strong>) …………………………. The light from the nearby Virgo<br />

galaxy set out when reptiles still dominated the animal world.<br />

A. the time to fly from one continent to another or the time it takes to drive to work<br />

B. a flattish disc of stars with two spiral arms emerging from its central nucleus.<br />

C. in which case they are called radio galaxies<br />

D. Most of the material universe is organized into galaxies of stars, together with gas and dust<br />

E. A galaxy is a giant family of many millions of stars<br />

F. spiral, elliptical, and irregular<br />

G. but they too are made more manageable by using a time calibration.<br />

H. the Andromeda galaxy.<br />

I. Their light was already halfway here before the Earth even formed<br />

J. The elliptical galaxies have a symmetrical elliptical or spheroidal shape with no obvious structure<br />

Your answer:<br />

1. _____ 2._____ 3._____ 4._____ 5._____<br />

6. _____ 7._____ 8._____ 9._____ <strong>10</strong>._____<br />

Part D. WRITING<br />
