Here’s a list of some interesting facts about stars.
The sun is the closest star to Earth.The sun is about 150 million kilometres away.Our sun,like most other stars,gives off power and light by nuclear fusion(核聚变),which happens exactly where it’s the hottest.The sun is about 4.5 billion years old and it will still last six billion years or so. When it runs out of its fuel (燃料),it would develop into a red star and increase in size.
Since stars are billions of light years away,it may be hard to recognise that stars are in continuous battles with themselves.All the stars have their own gravitational pull(引力) that pulls them.The surprising part is that the nuclear fusion occurring inside the star truly produces an outward(向外的) push to resist(抵抗) the gravitational force,which keeps its present shape.
Stars have different colours.The hottest stars are surprisingly the smallest ones and are blue in colour.Their temperatures go to about 12,000 kelvin.Although the yellow-coloured stars are the middle-sized ones just like the sun,their temperatures fall to about 6,000 kelvin.And lastly,the coolest and greatest ones are coloured red and the temperatures of them are about 3,000 kelvin.
When looking at the night sky,we may think that stars are up there alone.But don’t be surprised that these heavenly bodies in fact come in pairs.And stars can even come in groups of 3 or even 4!
1.What will happen when the sun runs out of its fuel
A.It will disappear slowly.
B.It will last six billion years.
C.It will become a white star.
D.It will become larger in size.
2.What can we learn from paragraph 3
A.All stars are in a state of balance.
B.It’s hard for the stars to keep their shapes.
C.The stars have the same gravitational pull.
D.The stars always stay in peace with one another.
3.What do we know about the colour of the star
A.It is blue when it is very cold.
B.It looks red when it is far away.
C.It seems yellow when it is over 3,000 kelvin.
D.It has something to do with its size and temperature.
4.How do all the stars appear in space in reality
A.They appear only in pairs.
B.They appear without rules.
C.They stay alone here and there.
D.They appear in small groups or in pairs.
