Star scientists have taken the first ever picture of a black hole, which is from a far away galaxy (银河系). It is 40 billion km across-three million times the size of the Earth-and has been described by scientists as "a monster".

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes (望远镜) across the world.

Details have come out today in Astrophysical Journal Letters. Prof Heino Falcke, says "It is one of the heaviest black holes that we think there is. It is a real monster."

The picture shows a quite bright "ring of fire", as Prof Falcke describes it. The bright halo is caused by superheated gas fling into the hole. The light is brighter than all the billions of other stars in the galaxy-which is why it can be seen so far away from Earth.

The dark circle at the centre is the point at which the gas enters the black holes, which is an object that has such a large gravitational (万有引力的) pull, not even light can escape.

In ancient times, a king had a big stone placed on a roadway. He wanted to see if anyone would move the stone out of the way. Some of the king's richest business men and courtiers (朝臣) came by and just walked around it.

Many people even loudly blamed the king for not keeping the roads clear, but none of them did anything about getting the stone out of the way. They just complained and went away.

A farmer then came along carrying a large bag of vegetables. When getting closer to the stone the farmer laid down his bag and tried to push the stone out of the road. After trying and pushing for long time, he finally. succeeded.

After the farmer went back to pick up his vegetables, he noticed a wallet lying in the road where the stone had been. In the wallet there were many gold coins and a note from the king explaining that the gold was for the person who moved the stone from the roadway.

If you were on the way, what would you do? Complain it or move it away? Every difficulty we come across in life gives us an opportunity to improve our situations, and while the lazy people complain, the others are creating opportunities through their kind hearts, generosity (慷慨大方) and willingness to get things done.

People in the United States honor their parents with two special days: Mother's Day, on the second Sunday in May, and Father's Day, on the third Sunday in June. These days are set to show love and respect for parents. They raise their children and educate them to be responsible people. They also give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.

These two special days are celebrated in many different ways. On Mother's Day, people wear carnations (康乃馨). A red one symbolizes a living mother. A white one shows that the mother is dead. On these days, families get together at home, as well as in restaurants. They often have outdoor barbecues for Father's Day. These are days of fun and good feelings and memories.

Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is "the thought that counts". Greeting card stores, flower shops, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.
