阅读下列应用文及相关信息,并按照要求匹配信息。首先,请阅读以下世界古代奇观的简介:

  A.  The Great Wall was begun more than two thousand years ago.  It was built to keep out invaders.  It extends about six thousand seven hundred kilometers across northern China.  Today,  the Chinese government is working to repairparts of the wall and protect as much of it as possible.  The Great Wall of China is one of the largest building projects ever attempted.  It is also the only object built by people that can be seen from space.

B.  The Coliseum in Rome,  Italy was built almost two thousand years ago.  The ancient Roman sports center could hold fifty thousand people who gathered there to watch public events.  Experts say it is one of the finest examples of Roman design and engineering.

C.  The city of Machu Picchu in Peru includes some of the best stone works ever built.  The ancient Inca people built Machu Picchu high in the Andes Mountains,  northwest of the city of Cuzco.  Machu Picchu is about thirteen square kilometers.  Historians say it might have been one of the last places of safety for the Incas who were fleeing invaders from Spain.

D.  India is famous for its temples and buildings.  The most famous is the Taj Mahal,  considered one of the most beautiful buildings ever built.  The fifth Mughal emperor,  Shah Jahan,  ordered it built in Agra in sixteen thirty-one.  He built it as a burial place in memory of his wife.  The Taj Mahal has tiny colorful stones inlaid in white marble.  The structure seems to change color during different times of the day and night.

E.  Abu Simbel was built more than three thousand years ago.  It is about 280 kilometers south of Aswan on the western bank of the Nile River.  It took an army of workmen and artists more than thirty years to cut the huge temple into the face of a rock mountain.  In front of the main temple are four huge statues of Ramses the Second.  Each statue is about twenty meters high.

F.  Stonehenge also belongs on a list of ancient wonders. It is a circle of huge stones in southeastern England.  Experts believe work began on Stonehenge about five thousand years ago.  We know very little about Stonehenge. We do not even know how these huge stones were moved to the area.  Much has been written about Stonehenge,  but experts say they still are not sure what it was used for.
