PART ONE: READING AND INTERPRETING (15)



Read the text carefully then do the activities:



Life On Other Planets ?



If there are living things on other planets, what are they like?
Scientists who try to answer this question are called astrobiologists.



Twenty years ago ,life on other planets seemed impossible. Astronauts
had visited the Moon and found no life on its surface. There were other reasons
too: some planets are so cold that there can't be any life on them ; on some
others there is such heat that life is unthinkable there. Most planets have no
water on the surface , and some planets have no atmosphere or they have a toxic
atmosphere.



However , in the 1990s scientists discovered some interesting species on
our own planet, Earth, They discovered
microbes living deep under the Earth's surface in temperatures of 160 degrees
Centigrade (160◦C); they found worms that can live in ice, and deep-sea animals
that eat only toxic chemicals.



Scientists now think species like these may live on some other planets
or moons, perhaps under the surface.



One possibility is Mars, which is the most similar to our planet . It is
a small planet with a diameter of about 6,800 Km and a surface
temperature between -100°C
and 0°C .



Some other possibilities are the moons of Jupiter which is the biggest
planet with a diameter of 143,000
Km.It has a lot of moons
; one of them is called Europa. It has a lot of water. There may be
oceans under its surface of ice. If there are oceans, does anything live in
them?

1-What type of
text is the reading passage?(1)


2- Answer these
questions according to the text4)


a) What prevented life to prevail on other
planets? Give two reasons.


b) Scientists made amazing discoveries on
earth. Which relation exist between those discoveries and life on other
planets?


c) What are Mars and Earth alike in?


d) Why is Europa one of the best possibilities
for life on other planets?


3-Are these
statements true or false according to the text? Put (T) for true and (F) for
false next to each one1,5)


a) Astrobiologists study the possible
conditions that facilitate life on other planets.


b) Scientists discovered many species living
over the earth's surface in temperature of 160°C.


c) Life may be possible on Jupiter's moons
because of the existence of a vital element
for life.


4-Find in the
text words or expressions that are closest in meaning to the following0,75)


a) poisonous(§2)= b) profound(§3)= c) identical(§5)=


5- Give the
opposites of these words by keeping the same roots0,75)


a) interesting=/= b) valid=/= c) appoint=/=


6- Add the
appropriate suffixes to the words between brackets to get a meaningful text1)


Satellites orbiting round the earth nave
provided (science) with a vast amount of ( inform) about conditions in outer
space. By comparison , relatively little known about the internal structure of
the earth. It has proved (easy) to go up than to go down. The (deep) hole ever
to be bored on land went down 25,340 feet. This problem has now been solved.


7- Put the verbs
between brackets in the correct tense2)


* Satellites are used for ( guide) ships at
sea.


* If there (be) no rotation and no differences
in the density of the rocks , the earth (be) a sphere.


* He ( believe)
that space exploration is a waste of time.
