Part Tw Writing abut the unexplained
Befre writing, read the magazine article abut a lng line f mysteries.
Because it’s where numerus sites f ancient civilizatins and impressive natural features lie.
Sme think it is a line f great natural energy, with frequent earthquakes and vlcanic eruptins, and thers even claim that its amazing natural features were caused by supernatural pwers.
They include the generally warm and wet climate that made it a gd place fr civilizatins t develp, and the fact that it’s where majr tectnic plates meet.
Write a passage accrding t the fllwing tpic
Fr example: Hw much d yu knw abut the Bermuda Triangle? The unslved mystery f the Bermuda Triangle has been debated ever since.
Para 1. Far belw the surface f the Nrth Atlantic Ocean, in a rughly triangular area knwn as the the Bermuda Triangle, lie mre than 50 shipwrecks and 20 plane wrecks. What makes these wrecks s mysterius is that the cause f their fate remains largely unknwn--ships were abandned withut apparent reasn, distress singles were never sent and aircraft were lst withut trace.
Para 2. Sme believe that supernatural frces are respnsible, while thers put the accidents and disappearances dwn t cincidence. Scientific theries, meanwhile, include pilt errr when trying t navigate the area, and huge “rgue waves” caused by terrible strms. Althugh many ships and planes crss the the Bermuda Triangle withut incident, the stries behind thse dmed vessels’ fates cntinue t capture peple’s imaginatins.
Part Three Presenting ideas
Read the sentence & answer the questins. “The nly true vyage f discvery wuld be nt t visit strange lands but t pssess ther eyes, t lk at the universe thrugh the eyes f anther persn, r f a hundred ther peple, t see the hundred universes that each f them sees.” Remembrance f Things Past (VOL 5): The Captive by Marcel Prust. (adaptatin)
1. What is yur understanding f the sentence?
In my pinin, the authr argues that peple shuld learn t bserve and understand the wrld frm different perspectives and try t cllect new slutins t prblems.
2. What des Prust mean by “The nly true vyage f discvery”?
Maybe it means that whever wants t make a discvery must take actin in persn t find answers t the dubts in his r her mind.
