Step 1 Warming up
1．Warming up by lking and talking
Shw the fllwing pictures t the students and let them knw abut the pwer f nature and talk abut them.
Sample expressins：
What happened in the pictures abve？D yu knw any ther natural disasters？Please wrk with yur partners and make a list f natural disasters(such as earthquake，snwstrm，fld，drught)．Have yu ever seen a vlcan?
(Sme new wrds：lava erupt/eruptin crater active/drmant/extinct vlcanes...)
2．Warming up by reading the passage belw.
Sme knwledge abut vlcanes
There are thusands f vlcanes all ver the wrld.What makes vlcanes？What happens?
The inside f the earth is very ht.Because it is very，very ht，the rck has melted like ice.It has becme liquid，like water.It is always biling，like water in a kettle.If yu have seen a kettle biling，yu knw that the steam and biling water try t get ut.The very ht melted rck inside the earth als tries t get ut.Usually it cannt because the utside f the earth is t thick and strng.
But in sme places the utside f the earth is thin and weak.Smetimes a crack(a small pening)appears.The ht melted rck，which we call “lava”，pushes up thrugh the crack and bursts thrugh.Steam and gas sht up int the air and the ht melted lava purs ut.Big pieces f rck may be thrwn high int the air.
After a while the vlcan becmes quiet again.The melted lava becmes hard.Later the same thing happens again and again.Each time mre ht lava purs ut n tp f the cld lava and then becmes hard.In this way a kind f muntain is built up，with a hle dwn the middle.Perhaps the vlcan will then be quiet and n mre lava will burst ut.Perhaps it will start again hundreds f years later.
Vesuvius is the name f a very famus vlcan in Italy.It first came t life many，many years ag.It was quiet fr hundreds f years.Then in the year 79 it suddenly burst.A great clud f smke sht up int the sky with great burning rcks，which fell all arund.Ht lava pured dwn its sides.Abut 3000 peple were killed.
Step 2 Pre－reading
1.Can yu imagine climbing int a live vlcan in rder t measure the temperature f the biling rck inside？Nw，read the fllwing passage please.
Why des Tazieff risk his life like this?
Harun Tazieff，the plish scientist，has spent his lifetime studying active vlcanes and deep caves in all parts f the wrld.In 1948，he went t Lake Kivu in the Cng t bserve a new vlcan which he later named Kitur.Tazieff was able t set up his camp very clsed t the vlcanes while it was erupting vilently.Thugh he managed t take a number f brilliant phtgraphs，he culd nt stay near the vlcanes fr very lng.He nticed that a river f liquid rck was cming twards him.It threatened t surrund him cmpletely.But Tazieff managed t escape just in time，he waited until the vlcanes became quiet and he was able t return tw days later.This time，he managed t climb int the muth f Kitur s that he culd take phtgraphs and measure temperatures.Tazieff has ften risked his life in this way.He has been able t tell us mre abut active vlcanes than any man alive.
2．Encurage students t talk mre abut vlcanes by lking at the fllwing pictures.
