It’s called the global positioning system.this global positioning system uses 24saturlists(satellites) that circle the earth.each of the satellites is consistently(constantly) sending out signals, and each signal contains important information that can be used to determine the longtitude,latitude and the elevation of any point on the earth surface.well in order to use this system to calculate mountain’s elevation,scientists needed to put a reciever to the(on its) summit to receive the signals from the satellites.the problem with this in fact(was that),in the past,the reciever was too heavy for climbers to carry.but now the recievers have been reduced to about the size of(and) weight of handheld telephone.so the climbers were able to take the reciever to the top of e and form there to exccess(access) the satellites system signals that allow them to determine the precise elevation.and it turns out the famous peak is actually a few feet higher than was priversely(previously) thought. + r: N5 l( g* v* Z, |

The winds of a tornado are the most violent and destructive winds on earth,any of you who have seen one knows very well how frightening and powerful they are.what interesting about emmigrate（them is）scientists don’t acctrually know exactly why tornados occur.we do know however what happens when tornados are formed.as you remember, a front occurs when the cool dry air from the north meets warm humid air coming from the south (from gulf of mexico for tornados in the US)when(where)these air masses meet,a narrow zone of

thatch group(a sturdy thatched roof)able to withstand heavy winds and last up to 100 years.how did they do it？well,in the north shal(a nutshell),thatching invovles covering the beings of afters(beam rafters)--the wooden scalate a number(skeleton of a) roof with rass(reeds) and straw.our thatche here have harvested their our natural metieral (materials)for the job—the bundles of water reeds you see lying over there beside the barn.)

$ P! D" T1 P( ZThatching is certainly uncommon in the us today.yes,(I guess)that’s why so many of you have come to see the demistration(demonstration).but wasn’t always that way.in the seventeen century,the colonists here thatched their roofs with reeds and straw,just to see a demin(as they had done) in england.after a while,though,they began to replace the thatch with wooden shegoes(shingles),because wood was so plentiful.and eventually,other roof materials like stone,clay tiles,slate,came into use.
$ K. S( M0 C' S7 y' ?7 q* D. rIt’s a real shame that most people today don’t realize how strong and long lasting the fechig（a thatched）roof is.in ireland ,where the fench(thatching) is still practiced,the roofs can survive winds of up to 110 miles per hour,that’s because straw and reeds are so flexible,they bend but don’t break in the wind like other materials can..another advantage is that the roof keep the house cool in the summer and warm in the winter.and then of course there is a roof’s long geberty(longevity),the average is 60years but it can last up to 100.with all the reasons to start thatching roofs again,wouldn’t it be wonderful to see this disappearing craft return to popularity.
