1--How many caves are there?
 
2--There were already more than 1，000 caves dug by the Tang Dynasty. However, nature  and  human  destruction have claimed a lot of them. Today,there are only 492 caves left.

1--莫高窟是什么时候开凿的?
2--第一个石窟是公元366年开凿的。
1--然后人们就继续开凿新石窟了，对吗?
2--是啊。这些石窟的开凿历经10个朝代，前后1000多年。
1--这里有多少个石窟?
2--到唐朝时已经有1000多个。然而，大自然和人为的损毁破坏了许多。今天只剩下492个。
1--这仍然是个了不起的数字。
2--你们可以看到，石窟一排排地排列，一排上面又有一排，有些地方形成了5层楼高的结构。
1--真是壮观!
2--是啊，我太喜欢莫高窟了。
1--我也是。
