12.Scientists found sea levels are rising faster today than anytime over the past 3,000 years.The sea level researchers gathered information going back 28 centuries,and their findings were released Monday by the Proceedings of the National Academy of Sciences.Robert Kopp,from Rutgers University in New Jersey,is the paper's lead author.He said the 20th century sea rise was"extraordinary"when compared to the past 3,000 years.And,Kopp said,"The rise over the last two decades has been even faster."
Scientists from NASA and the National Oceanic and Atmospheric administration reported that temperatures at the North Pole hit record highs in January.This news comes after 2015 has been the hottest year ever recorded.The earlier estimates show that temperatures around the Earth have risen more than a half degree Celsius since 1880.Scientists say that most of that rise is because of emissions,or gases,released into the air by machines that humans have built.
When temperatures rise,so do sea levels.That is because snow and ice melt,or break off from glaciers.They flow into the sea.The increased water makes the sea levels rise.
And it is not going to get better.The water is going to rise,said Stefan Rahmstorf,the study's co-author."I think we can definitely be confident that sea level rise is going to continue to accelerate if there's further warming."he told The New York Times.He said"inevitably there will be"more warming,which means it will continue to rise.
One question is how much will the sea levels rise?And for how long?The researchers said the Earth's sea level could rise more than a meter by the year 2100.
32.Scientists'findings about sea level rise are based on information throughB.
A.20 centuries B.28 centuries C.3,000 years D.two decades
33.What can we learn from paragraph 3?D
A.The North Pole had the highest temperature in 2015.
B.2015is the hottest year throughout the history of the earth.
C.Global temperatures have risen a half degree Celsius since 1880.
D.Human activities should be responsible for most of the global temperature rise.
34.Why do sea levels rise according to the passage?C
A.Water expands when heated.
B.When temperatures rise,it rains a lot.
C.Snow and ice melt and its water flows into seas.
D.Scientists haven't found the reason so far.
35.What does this article mainly talk about?B
A.The consequences of sea levels'rise.
B.Sea levels rise with temperatures'rise.
C.The reasons of high temperatures.
D.Global temperatures have hit a record high.
分析 主要讲述了现在随着环境的破坏,人类行为的不当,使得海平面上升.海平面的上升使得人类的未来有了隐患.
解答 32.D 细节题.根据文章内容The sea level researchers gathered information going back 28 centuries,and their findings were released Monday by the Proceedings of the National Academy of Sciences.由此可知,科学家对海平面上升的发现是基于28 centuries,结合选项,故选D
33.B 细节题.根据文章内容Scientists say that most of that rise is because of emissions,or gases,released into the air by machines that humans have built.科学家说,温度的上升、海平面的上升主要是人类使用的机器排放有害气体,并释放到空气中,结合选项,故选B
34.C 细节题.根据文章内容When temperatures rise,so do sea levels.That is because snow and ice melt,or break off from glaciers.They flow into the sea.The increased water makes the sea levels rise.当温度上升,海平面也上升.那是因为雪和冰都化了,然后流入到海洋里,迅速聚集的水使得海平面上升,结合选项,故选C
35.B 主旨题.根据文章内容,主要讲述了现在随着环境的破坏,人类行为的不当,使得海平面上升.海平面的上升使得人类的未来有了隐患.结合选项,故选B
