Say the phrase“female environmental pioneers”,and among the names you will hear Rachel Carson,who wrote about pesticides;chimpanzee expert Jane Goodall;and 17yearold climatechange activist Greta Thunberg.To mark Women's History Month,Kidspost is sharing the story of an environmental pioneer who is not that famous but equally remarkable.
At age 3,Sylvia Earle found her lifelong passion while playing on a beach.A wave suddenly came up and knocked her over.
“My mother...saw the big smile on my face and let me run back in,”Earle told a TV interviewer years later.“And I've been running back in ever since.”
Earle is now 84 years old and has spent a lifetime exploring the world's oceans and working to protect them from pollution,overfishing and other threats.
She is a pioneer in using scuba gear.Scuba gear lets divers take breath underwater.She holds the world record for the deepest untethered walk on the ocean floor at 1,250 feet.This means she was not tied to anything when she was walking underwater.During this exploration,she planted a U.S.flag.
In 1998,Time magazine gave Earle its first Heroes for the Planet award.She was the first female chief scientist at the National Oceanic and Atmospheric Administration (NOAA).It is the U.S.ocean and atmosphere group.She was also elected to the National Women's Hall of Fame.
Earle has spent her life teaching people about the ocean.She notes how much it affects the weather,and what we eat and drink.She has something to say to those who don't understand why the ocean matters.“They should know that with every breath they take,every drop of water they drink,the ocean is touching them,”Earle says.“You should treat the ocean as if your life depends on it—because it does.”
[语篇解读] 本文是一篇新闻报道。文章主要讲述了一位一生都致力于探索海洋保护海洋的女性环保先锋——Sylvia Earle,三岁时就发现了自己对于海洋的热爱,并在保护海洋方面做出了杰出贡献和成就。1998年,《时代》杂志给了Earle第一个行星英雄奖。她是美国国家海洋和大气管理局(NOAA)的第一位女性首席科学家。她还入选了全国妇女名人堂。同时,她提出了海洋对于人类的重要性。

It seems we can't get off the planet fast enough.Two thirds of NASA's money is spent on manned space exploration,and that number will grow with the USA's decision to send a man to Mars in 2037.We've seen all there is to see on Earth,right?Wrong.The final place is here,under the surface of the sea.
Heading down into the ocean,human limits are quickly reached.At a depth of 200 metres,the water is as black as a moonless night.Most nuclear submarines (核潜艇) would implode (内爆) before they reach 1 km down.At a depth of 3 km—still less than the average depth of the ocean—there's a good chance that you'll discover a new species.The deepestdiving whales go no further.At the very bottom,about 11 km down,lies the Challenger Deep,the deepest part of the Mariana Trench in the Pacific Ocean.Eighteen humans have walked on the Moon,but only three have seen the Challenger Deep with their own eyes.
Yet things live down there.Big things.A very loud sound was once heard and scientists suggested that it was produced by an animal bigger than a blue whale,the largest creature known on the planet.
In the late 1990s,a deepwater submarine was dropped in the Southern Ocean,and passing 4,000 metres,it discovered something huge passing under it.Surprised?Don't be.The ocean covers 70% of the planet's surface and we've studied less than 5% of it.We know more about the dark side of the Moon than about the bottom of the sea.
One reason that we explore space is to find evidence of other life forms.The search for life outside of Earth is important,but robots can look under the dry rocks of Mars better than humans.They're absolutely important for doing ocean research too,but they can't look under the sea.The cost of exploration is rising,but the results would benefit all our lives.Understanding the oceans will help us find new sources of food,drugs and energy.
Perhaps now it's time to begin a new period of sea exploration.Manned exploration of space is science fiction.The adventure of the deep sea is science fact.
[语篇解读] 本文是一篇说明文。文章通过对the Mariana Trench和Southern Ocean海底勘探的描述,指出人类对深海的探索或许比对太空的探索更具有现实意义。
5.What do the examples in Paragraph 2 suggest?
A.Sea exploration is no easy task.
B.Nuclear submarines need to be improved.
C.The ocean is far deeper than people expected.
D.The condition under the sea is similar to that on the Moon.
A [细节理解题。由第二段中的“Eighteen humans have walked on the Moon,but only three have seen the challenger Deep with their own eyes.”可知,比起探索太空,人类对于深海的探索更艰难。]
6.What do we know about the Challenger Deep?
A.Blue whales live there.
B.No one has ever been there.
C.People are terrified by the sight of it.
D.It is the deepest known location on Earth.
D [细节理解题。由第二段中的“At the very bottom,about 11 km down,lies the Challenger Deep,the deepest part of the Mariana Trench in the Pacific Ocean.”可知,the Challenger Deep位于海底大概11千米的位置,是the Mariana Trench最深的部分。]
7.What does the author think of the discovery in the Southern Ocean?
A.It's surprising. B.It's no wonder.
C.It's worrying. D.It's no success.
B [细节理解题。由第四段中的“...it discovered something huge passing under it.Surprised?Don't be.The ocean...about the bottom of the sea.”可知,对于在Southern Ocean中的发现,作者并不感到惊讶,地球表面70%被海水覆盖,人类对于它的研究还不到5%。对月球阴暗面的了解都比海底多。]
8.What does the author want to tell us?
A.Space exploration is of little value.
B.We spend too much money on space travel.
C.Humans' success lies in how much they explore the sea.
D.The ocean is the place where we should make our efforts.
D [主旨大意题。由倒数第二段最后两句话可知,探索海底虽然费用高一些,但可以帮人类找到更多食物、药品和能量来源,对人类的实际意义更大。]

“Shine in the dark”dolphins may seem like something straight out of a science fiction movie.However,that is precisely what Newport Coastal Adventures' Captain Ryan Lawler and professional videographer Patrick Coyne witnessed,when they set out to explore the spectacular blue tides that have been lighting up the waters off Southern California's coast since midApril.
The partner scanned the ocean for hours and was returning to shore when they spotted the“electric”dolphins swimming through the bloom of shining plankton (浮游生物).The videographer,who had seen the phenomenon only once before in a Netflix show,says catching the scenes proved to be a lot harder than he had expected.“For starters,the shining plankton has sweet spots to where it shows up and then fades away,so while on the water,it's impossible to just find it,”Coyne says.“Also,conditions have to be absolutely perfect for the shining plankton to show and for animals to swim through it so we can film it.”
Though witnessing shining sea life is rare,the electrifying blue ocean scenery is a fairly common sight around Southern California between February and September.The phenomenon can be attributed to the presence of millions of plankton,which tend to gather and reproduce in large quantities in the warm coastal waters during this time.
Though a majority of California's red tides are caused by plankton species that do not produce deadly poison,some algal blooms (藻花) can be dangerous for sea animals,especially when they stay for long periods of time.In 2018,an almost yearlong “red tide” along Florida's Gulf coast caused by the excessive growth of microalgae Karenia Brevis,killed hundreds of fish and other sea animals.
[语篇解读] 本文是一篇说明文。文章介绍了发光的浮游生物,并且说明了浮游生物过度生长会导致海洋生物的死亡。
9.What does the underlined phrase “sweet spots” in Paragraph 2 mean?
A.A sea plant. B.A lost world.
C.A perfect moment. D.A missing camera.
C [词义猜测题。由第二段中的“For starters,the shining plankton...it's impossible to just find it”可知,发光的浮游生物在它们出现和消失的地方都有自己的闪光点,“sweet spots”指的是浮游生物出现和消失的地方,是一个完美的时刻。]
10.What is the main reason for the sea life shining?
A.They absorb the light in the ocean and then reflect it.
B.They are surrounded by millions of shining plankton.
C.They swim through the ocean with electricity in large quantities.
D.They benefit from the warm water to power themselves.
B [细节理解题。由第三段“Though witnessing shining sea life is rare...during this time.”可知,海洋生物发光的主要原因是它们被数百万闪亮的浮游生物包围着。]
11.What caused the death of some sea animals according to the text?
A.Red tides.
B.Human exploration.
C.Warm water.
D.Algal blooms.
D [细节理解题。由第四段“Though a majority of California's red tides...killed hundreds of fish and other sea animals.”可知,造成海洋生物死亡的原因是藻类的繁殖。]
12.In which section of a newspaper may this text appear?
A.Science. B.Health.
C.Entertainment. D.Education.
A [推理判断题。根据文章内容可知,文章介绍了发光的浮游生物,以及说明了浮游生物过度生长会导致海洋生物的死亡。可以推断,这篇说明文可能出现在报纸的科学版面。]
Ⅱ.七选五
The Bermuda Triangle is a nearly halfmillion squaremile area of ocean roughly defined(定义) by Bermuda,Puerto Rico,and the southernmost tip of Florida.Drawing an imaginary line to link these three places creates the three sides of a triangle (三角).
There is a mystery surrounding the Bermuda Triangle. 1 Some people believe that at least fifty ships and twenty planes have disappeared there during the past one hundred years.
The accident that first suggested the danger of the Bermuda Triangle was the disappearance of five American Navy planes in 1945.The planes carried fourteen people on a training flight. 2 And a plane sent to search for them also disappeared.Newspaper reporters and other writers called the planes the Lost Patrol.They began trying to explain the tragic events. 3 One writer said there were powerful forces under the water.These forces interfered with communication devices and caused planes to crash and ships to sink.Another writer said creatures from outer space guarded the area. 4
Some critics said the Bermuda Triangle stories were false.They said most of the events that took place in the area could be explained scientifically.And they said most of the accidents linked to the Bermuda Triangle did not happen there.Critics said only about five real accidents happened within the triangle's borders.The United States Coast Guard agreed. 5
A.They never returned.
B.Some of the explanations were strange.
C.No broken ships or dead bodies have been found so far.
D.These creatures pulled the planes and ships to another planet.
E.The area seems to be extremely dangerous to airplanes and ships.
F.It is known as “The Triangle of Death” for its strange seawater and sudden storms.
G.It said the stories about it were mostly science fictions and should not be taken seriously.
[语篇解读] 美国海岸警备队对这些年来百慕大魔鬼三角发生的很多轮船和飞机失踪事件进行了回顾,并没有发现有任何证据显示这些事件是由超自然因素造成的。
1.E [根据“一些人认为在过去的一百年里至少有五十艘船只和二十架飞机消失在那里”可知,E项“那个地方对飞机和轮船特别危险”可引出下文。]
2.A [根据上文的“...the disappearance of five American Navy planes in 1945”和下文的“And a plane sent to search for them also disappeared.”可知,那些飞机失踪了,所以选A项。]
3.B [根据下文的“一位作家说水下有强大的力量……”可知,一些解释很奇怪,所以B项能引出下文。]
4.D [上文提到“一些外星生物”,由此可知,D项“这些生物把飞机和船劫持到了另一个星球”可承接上文。]
5.G [空处是本文的最后一句。G项“美国海岸警备队说,关于它的故事大多是科幻小说,不应该当真”可作为本文的总结。]
