An Announcement

It was a small town which lay by the coast.Most people there lived by catching fish.The hurricanes often struck the area from July to October.Some of the people died on the sea when their boats were blown over by the high winds.So they paid much attention to the weather forecasts.They were afraid to meet with the hurricanes when they were catching fish on the sea.Each of the families had a radio and people always took them with themselves and listened to them at any time.

It was September.A hurricane attacked the town one night.Plenty of trees were pushed over and all the electric and telephone lines were broken.People couldn’t watch TV,or call their friends,or go to work.To their anger,they couldn’t listen to the weather forecasts the Town Radio Station broadcast.The food and fresh water would soon be short and the patients couldn’t be given medical care—no medicine could be carried there.People didn’t know what would happen and they looked anxious.

On the fourth day they read an announcement(通告)on the Town Weekly.It was written,“Recently we have to stop the weather forecast because of the bad weather.We usually get the forecasts from the airport.But the roads are all blocked by the fallen trees and stones.Whether or not we’ll be able to broadcast the weather forecast tomorrow depends on the weather!”

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 4 billion, 600 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 5 billion years from now, the core of the sun will shrink and become hotter. The surface temperature will fail. 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 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 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 onto the earth’s surface.

The word "there" underlined in Paragraph 4 refers to ______ .

A.our own planet

B.the outer surface of the sun

C.the core of a black dwarf

D.the planet mercury
