BBC纪录片:美丽中国--长城以外7
【双语参考文本】Even out here in the semi-deserts, the Wall continues its long march.Here, it's made of little more than compacted earth.But with hardly any rain falling, it's suffered very little erosion over the centuries.Hundreds of thousands of people lost their lives building it.Yet it seems hard to believe that anyone felt that these distant wastelands needed protecting.But the Wall still has one final surprise.This is Jiayuguan, the mighty fortress in the desert.Built in the Ming dynasty over 600 years ago, legend says that the construction of the fortress was so meticulously plannedthat 100,000 bricks were specially made and only one brick was left unused.This fortress marks the end of the Great Wall of China.The greatest man-made barrier on earth.But ahead lies an even more formidable barrier.A vast no-man's land of deserts that stretch westward to the borders of Central Asia.
