Loulan, which corresponds to Pompeii buried under the desert, always intrigues me.So I was thrilled when I won a trip to it.I set out on 23 July and arrived on 30 July.Seeing the ruins in front of me, I couldn't dismiss the idea that this city was once busy and had notable civilisation.
There was a scholar in our team who had thrown himself into the archaeological research of Loulan for years.With him being our guide, we learnt a lot about this mysterious city.The reason why Loulan was abandoned and fell into ruin is unclear.Some believe that the downfall of this civilisation is because of climate change.The residents had no choice but to make a getaway and run for their lives.
楼兰，相当于埋藏在沙漠下的庞贝，总是让我感到好奇。因此，当我赢得了一次旅行的机会时，我非常激动。我于 7 月 23 日出发，7 月 30 日抵达。看到眼前的废墟，我不禁想到，这座城市曾经繁华过，有过重要的文明。
我们团队中有一位学者，多年来一直致力于楼兰的考古研究。在他的带领下，我们了解了这座神秘城市的许多情况。楼兰被遗弃和沦为废墟的原因尚不清楚。有人认为，楼兰文明的衰落是因为气候变化。居民们别无选择，只能逃亡。

[选自：选修教材　人教版·选修一(新教材)　UNIT 3 P64]
Luding Bridge was built centuries ago. Thirteen heavy iron chains, with a span① of some 100 yards or more, were stretched across the river, their ends imbedded② on each side under great piles of cemented rock, beneath the stone bridgeheads③. Thick boards lashed④ over the chains made the road of the bridge, but upon their arrival the Reds found that half of this wooden flooring had been removed,
and before them only the bare⑤ iron chains swung to a point midway in the stream. At the northern bridgehead an enemy machine gun nest faced them, and behind it were positions⑥ held by a regiment⑦ of White troops. The bridge should, of course, have been destroyed, but the Sichuanese were sentimental about⑧ their few bridges; it was not easy to rebuild them, and they were costly⑨. And who would have thought the Red Army would insanely⑩ try to cross on the chains alone But that was what they did.
①span n．跨度；持续时间
②imbed v．埋藏
③此处为独立主格结构
④lash v．捆绑
⑤bare adj.光秃秃的
⑥此处为介词短语置于句首引起的全部倒装
⑦regiment n．(军队的)团
⑧be sentimental about对……充满感情
⑨costly adj.昂贵的
⑩insanely adv.疯狂地
1．What does the underlined word “it” refer to
___________________________
An enemy machine gun nest.
2．Why was the Luding Bridge not completely destroyed by the enemy forces before the Reds arrived
___________________________________________________________
The Luding Bridge was not completely destroyed by the enemy forces because the Sichuanese were sentimental about their few bridges. It was not easy to rebuild them, and they were costly. The enemy likely did not anticipate that the Red Army would attempt to cross on the chains alone, which was what they ended up doing.
【识文知意】　泸定桥建于数百年前。13条沉重的铁链横跨河面，跨度达100码甚至更长，铁链两端埋在石块砌成的桥头堡下面，用水泥封住。铁链上捆着厚厚的木板，构成了桥面，但当红军到达时，他们发现一半的木板已被拆除，在他们面前只剩下光秃秃的铁链在河中央摆动。在北面的桥头堡，有个敌人的机枪阵地正对着他们，其后面是敌军一个团据守的阵地。当然，这座桥本应该被炸毁的，但四川人对他们为数不多的桥梁感情很深。重建这些桥梁并不容易，而且代价高昂。谁会想到红军竟然会拼命地试图独自穿过铁链过河呢？但他们确实这么做了。
