THE NIGHT THE EARTH DIDN'T SLEEPStrange things were happening in the cuntryside f nrtheastern ① Hebei.Fr several days，the water in the village wells② rse and fell，rse and fell.There were deep cracks③ that appeared in the well walls.At least ne well had sme smelly gas④ cming ut f it.【1】 Chickens and even pigs were t nervus t eat，and dgs refused t g inside buildings⑤.Mice ran ut f the fields lking fr places t hide, and fish jumped ut f the water.【2】 At abut 3：00 a.m.，n 28
July 1976，bright lights were seen in the sky utside the city f Tangshan and lud nises were heard.But the city's ne millin peple were asleep as usual⑥ that night.
【1】句中cming ut f it为动词-ing形式短语作后置定语，修饰gas。gas与cme之间为逻辑上的主谓关系。【2】句中and连接表示顺承关系的并列句，第一个分句中lking fr places t hide为动词-ing形式短语作伴随状语，Mice与lk fr之间为逻辑上的主谓关系，“寻找”与“跑”同时进行。
At 3：42 a.m.，everything began t shake.It seemed as if⑦ the wrld were cming t an end⑧！Eleven kilmetres directly belw⑨ the city，ne f the mst deadly earthquakes⑩ f the 20th century had begun，a quake that even caused damage mre than⑪ 150 kilmetres away in Beijing.【3】 Nearly ne third f the whle natin felt it! A huge crack，eight kilmetres lng and 30 metres wide，cut acrss huses，rads，and waterways.Hard hills f rck became rivers f dirt.In less than ne minute⑫，a large city lay in ruins⑬.Tw thirds f the peple wh lived there were dead r injured.Thusands f children were left withut parents.The number f⑭ peple wh were killed r badly injured⑮ in the quake was mre than 400，000.【4】
【3】句中a quake that even Beijing为ne f the mst deadly earthquakes的同位语，其中that even Beijing为that引导的定语从句，修饰先行词a quake，that在从句中作主语。【4】句中wh引导定语从句，修饰先行词peple。
Everywhere survivrs lked，there was nthing but ruins.Nearly everything in the city was destryed.Abut 75 percent⑯ f the city's factries and buildings，90 percent f its hmes，and all f its hspitals were gne.Bricks⑰ cvered the grund like red autumn leaves，but n wind culd blw them away⑱.Mst bridges had fallen r were nt safe t crss.【5】 The railway tracks were nw useless pieces f metal⑲.Tens f thusands f cws，hundreds f thusands f pigs，and millins f chickens were dead.Sand nw filled the wells instead f⑳ water.Peple were in shck㉑—and then，later that afternn，anther
big quake shk Tangshan again.Even mre buildings fell dwn㉒.Water，fd，and electricity㉓ were hard t get.Peple began t wnder hw lng the disaster wuld last. 【6】
【5】此处是“主语＋be＋adj.(＋fr sb.)＋不定式”句型，不定式用主动形式表示被动意义。下文中的Water，fd，and electricity were hard t get.也属于此句型。【6】句中hw引导宾语从句，同时作状语，修饰形容词lng。
But hpe was nt lst.Sn after the quakes，the army sent 150，000 sldiers t Tangshan t dig ut㉔ thse wh were trapped㉕ and t bury㉖ the dead.【7】Mre than 10，000 dctrs and nurses came t prvide medical care㉗.Wrkers built shelters fr survivrs whse hmes had been destryed.Hundreds f thusands f peple were helped.Water and fd were brught int the city by train，truck，and plane.Slwly，the city began t breathe㉘ again.
【7】句中t dig t bury the dead为两个并列的动词不定式作目的状语，其中wh were trapped为wh引导的定语从句，修饰先行词thse；先行词为thse且指人时，定语从句要用wh引导。the dead表示“死者”，属于“the＋adj.”结构。
Tangshan started t revive㉙ itself and get back up n its feet㉚.With strng supprt frm the gvernment and the tireless㉛ effrts㉜ f the city's peple，a new Tangshan was built upn the earthquake ruins.The new city has becme a hme t㉝ mre than seven millin peple，with great imprvements in transprtatin，industry，and envirnment.Tangshan city has prved t China and the rest f the wrld that in times f㉞ disaster，peple must unify㉟ and shw the wisdm㊱ t stay psitive and rebuild㊲ fr a brighter future.【8】
【8】本句使用了“prve ”结构，that引导的宾语从句作prve的直接宾语；其中t stay psitive为不定式短语作后置定语，修饰抽象名词wisdm。
地球的不眠之夜河北省东北部的农村地区怪事连连。一连几天，村里的井水升升降降，起起伏伏，井壁上出现了深深的裂缝，至少有一口水井冒出臭气。鸡甚至猪都焦躁不安，不愿进食；狗拒绝进入屋内。老鼠跑到田外，寻找藏身之所；鱼儿也跳出水面。1976年7月28日凌晨3：00左右，唐山城外的天空中出现了耀眼亮光，接着又传出巨大的声响。然而，那天晚上城里的百万居民仍像往常一样沉睡在梦乡。
凌晨3：42，万物开始摇晃，仿佛世界末日即将来临！在城市正下方的11千米处，20世纪伤亡最严重之一的一场地震爆发了，远在150多千米以外的北京都受到了这场地震的破坏，全国几乎三分之一的地区有震感！一条8千米长、30米宽的巨大裂缝横切房屋、道路和水路。坚硬的石山变成了泥石流。在不到一分钟的时间里，一座大城市沦为废墟。城里三分之二的居民在地震中死亡或受伤，数以千计的孩子失去了父母。在此次地震中丧生或身受重伤的人数超过了40万。
幸存者目及之处无一不是废墟，万物尽毁。市内大约75%的工厂和大楼、90%的住房和所有的医院都倒塌了。砖块就像秋天的红叶覆盖着地面，但是却没有风能将其吹走。大多数桥梁不是坍塌了，就是无法安全通行了；铁轨变成了废金属块。数万头奶牛、数十万头猪和数百万只鸡也都死掉了。沙子灌满水井，井水消失殆尽。人们惊恐万状，然而临近傍晚时分，又一次强烈的地震撼动唐山。更多的楼房倒塌了，没有水和食物，电也停了。人们心里开始疑惑这场灾难还会持续多久。
