Huge Waves Destrying Arctic
Ice Faster than Expected
Ice cvers much f the Arctic Ocean. Sme pieces f ice are huge, like mving islands. As temperatures have increased, hwever, sme f the ice has begun t disappear. Scientists have discvered huge waves in the arctic waters.
The waves were discvered by accident in May, 2010. Scientist Aleksey Marchenk and his students set ut n a trip. They wanted t study the icy waters.
The ship travelled east and stpped next t a large blck f ice arund 50 miles frm the small island f Hpen. Marchenk prepared t lead his students ut nt the ice.
“We were ready t g but when I went ut, I discvered many cracks arund,” he remembers.
He decided t mve the ship deeper int the ice t keep safe. The farther in they went, he thught,the harder the ice wuld becme. As they pushed frward, hwever, the ship experienced small waves, and then bigger nes. Sn, the waves brke up the ice arund the ship int thusands f smaller pieces.
Within an hur, Marchenk and his team saw a wave that was abut 13 feet high. The ship’s navigatin system finally recrded the largest waves. They were mre than 20 feet in height. The waves were s strng that they frced huge pieces f ice t jump up and dwn, breaking the ice int smaller pieces within just ne hur. Scientists had never imagined that the prcess culd happen s fast. The waves in these areas used t be small.
The speed and frce f the huge waves there makes it impssible t knw in advance when they are cming. That culd be dangerus fr navigatrs and lcal cmmunities wh are unprepared fr huge waves r depend n sea ice t prtect them. Wildlife like plar bears that depend n sea ice t live is als in danger.
Sme scientists think peple will sn see even bigger waves in icy waters. As waves break up ice, seas will be mre pen, and waves will be strnger. There are strmy times ahead.

Dear schlmates,
Elephants are the largest mammals n land.They can live as lng as 80 years. Hwever, these days the number f elephants is becming much smaller. Because peple cut dwn frests they are lsing their hmes. Als, peple kill them fr their ivry. Elephants are in great danger. I think we shuld try ur best t prtect them. First, we shuld help make rules t stp peple frm killing elephants. Secnd, we shuldn’t cut dwn trees. Third, we shuldn’t buy anything made f ivry.
I believe everyne’s cntributin (貢獻(xiàn)) can make a big difference.
