The sun today is a yellow dwarf star It is powered by thermonuclear reactions near its center that change hydrogen into helium The sun has existed in its present state for about 4 billion, 600 million years and is thousands

of time greater than the earth

By studying other stars, astronomers can predict what the rest of the sun's life will be like About 5 billion years from now, the core of the sun will become smaller and hotter The surface temperature will fall The higher temperature of the centre 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 hot for life to exist

Once the sun has used up its thermonuclear energy as a red giant, it will begin to shrink After it becomes smaller

to the size of the earth, it will become a whit dwarf star The sun may throw off huge amounts of gases in violent

eruption called nova explosions as it changes from a red giant to a white dwarf.

A To alert people to the dangers posed by the sun B To discuss conditions on earth in the far future

C To present a theory about red giant stars D To describe changes that the sun will go through

2 It can be inferred from the passage that the sun

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

B has been in existence for ten billion years

C will continue as a yellow dwarf for another ten billion years

D is rapidly changing in size and brightness

3 What will probably be the first stage of change as the sun becomes a red giant?

A Its core will cool off and use less fuel

B Its surface will become hotter and shrink.

C Its sun will throw off huge amounts of gases

D Its centre will grow smaller and hotter

4 When the sun becomes a red giant, what will conditions be like on earth?

C It will become too hot for life to exist

D It will be destroyed in nova explosions
