Lk at the pictures and answer the questins.
Huanglng, China: Lcated in the nrth f Sichuan, Huanglng is a histric and scenic area widely knwn fr its clurful pls, ht springs, valleys, waterfalls, snw-capped peaks and diverse frest.The areaals has a ppulatin f endangered animals, including the giant panda and the Sichuan glden snub-nsed mnkey.
Iguazú Falls, Argentina and Brazil: The Iguazú Falls stretch in width fr 2.7 kilmetres (r 1.7 miles). Their height varies between 60 metres (200 feet) and 82 metres (r 269 feet). They feature ver 275 individual falls that thunder int the Iguazu River. Special walkways have been built arund the Iguazu Falls t allw visitrs t get clse up t this wnder f their natural beauty and pwer.
Munt Kilimanjar, Tanzania: Lcated in nrth-east Tanzania, Munt Kilimanjar is the highestmuntain in Africa and the wrld’s tallest free standing muntain, abut 5,895m abve sea level. The muntain is encircled by muntain frest. Munt Kilimanjar cnsists f three principal vlcanes: Kib (centre), Mawensi (east), and Shira (west). Shira and Mawensi are extinct vlcanes. Hwever, Kib is a drmant vlcan; it can erupt again. The muntain has been the subject f many scientific studies because f its shrinking glaciers and disappearing ice fields.
Uluru, Australia: Uluru, als knwn as Ayers Rck and fficially gazetted as "Uluru / Ayers Rck", is a large sandstne rck frmatin in suthwestern Nrthern Territry, central Australia. Uluru is sacred t the Abriginal peple f the area. Uluru / Ayers Rck rises 348 metres abve the surrunding desert plain and reaches a height 863 metres abve sea level. The area arund the frmatin is hme t an abundance f springs, waterhles, rck caves and ancient paintings.
2. What d these places have in cmmn?
They are all included n the Wrld Heritage List.
Watch the vide and answer the questins.
1 What are the three types f Wrld Heritage Sites?2 What ther natural heritage sites in China d yu knw f?
There are three types f the Wrld Heritage Sites, cultural, natural and mixed. A mixed heritage site is a site that has bth cultural and natural significance.
Wrk in pairs and cmplete the quiz.
1. Which is the highest railway in the wrld?a The Trans-Siberian Railway.b The Qinghai-Tibet Railway. c The Chengdu-Kunming Railway.2. In which year was the cmpleted Qinghai-Tibet Railway put int peratin?a 1984 b 2001 c 2006
3. Which f these statins is nt n the Qinghai-Tibet Railway?a Lhasa.b Gl mud.c Lanzhu.4. Which f these natural Wrld Heritage Sites des the Qinghai-Tibet Railway pass by?a Xinjiang Tianshan.b Qinghai Hh Xil.c Suth China Karst.
Find ut why the railway is particularly special t the authr.
The authr has wrked n the Qinghai-Tibet Railway, and as the highest railway in the wrld and being claimed t be “impssible”, the railway is a recrd f all the effrts made by the authr and ther peple wh wrked n it t vercme the mst difficult engineering challenges. All f these make the railway special t the authr.
Part 1: Para 1-2When cnsidering vercming the mst difficult engineering challenges, hw t prtect the delicate ecsystem was amng ur tp cncerns.
Part 2: Para 3-6The challenges and slutins.
Part 3: Para 7We built the Qinghai-Tibet Railway with care that the envirnment desreves.
Organizatin f the passage
Chse the authr's purpse in writing the passage and give yur reasns.
1 T prve that humans can cnquer nature.2 T highlight the amunt f wrk required t build the Qinghai-Tibet Railway.3 T praise the wrkers’ effrts in building the Qinghai-Tibet Railway.
Paragraph 2“Taking years t cmplete, the Qinghai-Tibet Railway is a recrd f all f ur effrts t vercme the mst difficult engineering challenges.”
shws that the wrkers made a great effrt t build the Qinghai-Tibet Railway.
Frm Paragraph 2 t Paragraph 6 the authr tells us the challenges they met when cnstructing the railway and the measures they tk t slve the prblems. Frm these we can tell the wrkers make a great effrt t build the Qinghai-Tibet Railway.
Paragraph 6“I feel a sense f pride and achievement”Paragraph 7“I am prud that we built ur ‘impssible’ railway in the wrld with the care the envirnment deserves.”
All f these indicate that the authr’s purpse is t praise the wrkers’ effrts in building the Qinghai-Tibet Railway.
Cmplete the table.
Thirty-three passages
mve safely and freely in their natural habitat
prevent damage t wetlands and grasslands
a ttal length f abut 160 kilmetres
mved t a new area
Several xygen-making statins
regular breaks
build a twenty-kilmetre wall
prtect it frm cnstructin waste
prtect Cuna Lake
1. They have t apply state-f-the-art techniques t prtecting the permafrst in the subgrade f the railway embankment;2. They need t make regulatins t ensure the envirnmental dispsal f the cnstructin waste;3. They must vercme prblems brught abut by cmplex tpgraphy.
Nw d sme nline research t find ut what ther challenges were met and vercme by the railway wrkers .
1 Which f the slutins are yu mst impressed by? Why?2 Which wrds in the passage are used t describe the Qinghai-Tibet Railway? What ther wrds culd yu think f t describe it?3 What changes d yu think the Qinghai-Tibet Railway has brught t the peple living alng the railway?4 What methd did yu use t cllect infrmatin? Hw did the infrmatin help yu t better understand the passage?

Pssible answers:1. Students’ wn answers.2. Sky Railway, highest, impssible, extrardinary; Yu can als say it is a miracle, great achievement, etc.3. The railway has made it cnvenient fr peple t travel arund; it has prmted the lcal ecnmy; it has imprved peple’s living standard, etc.4. Yu can use reading skills like scanning t cllect infrmatin. In this way yu can put aside unimprtant cntent and fcus n the infrmatin yu are searching fr, and then it will help yu sum up the main idea quickly.
