Scientists have recently discvered the wrld’s largest knwn field f seagrass.They did it using vides sht by sme extrardinary helpers.The wrk shuld help prtect the seagrass,and als shws ff a pwerful way t explre the cean.
As a shelter fr many sea creatures,seagrass is a flwering plant that nrmally grws in shallw waters near casts.They grw in thick fields,knwn as seagrass meadws(海草草场),which help clean the cean water.Mre imprtantly,they are called “cean lung”.They help in the fight against the climate crisis.That’s because they stre huge amunts f carbn—the majr surce f glbal warming.Damaging these seagrass meadws can release this pllutant again,making things wrse.
Cnsidering the urgent need t prtect seagrass meadws,scientists are eager t knw abut their size and number.Hwever,the meadws can be hard t spt frm abve,either because the water is t deep r nt clear enugh.And the cean is s huge that it’s hard t study them by diving.S scientists decided t have tiger sharks help the research.
Tiger sharks are inbrn fast swimmers,and spend a lt f time in seagrass meadws.Between 2016 and 2020,the researchers attached cameras and ther trackers t the fins f seven tiger sharks,and then let them g again.The cameras were designed t fall ff after hurs and flat t the surface.Tracking signals helped find the flating cameras and cllect the vides the sharks had taken while traveling fr miles.Mrever,ther tls were used,including satellite images,as well as images taken by divers and bats.
Putting all this infrmatin tgether,the scientists learned that the waters arund the Bahamas are hme t the largest seagrass meadw ever discvered.And the meadws cver at least 25,500 square miles,and culd be as large as 35,500 square miles.
Different frm previus studies,the prgram discvers hw useful large underwater animals can be in helping t learn mre abut life under the sea.Oliver Shipley,a scientist frm the team,says animals like tiger sharks are ging t take us t new places that we didn’t knw existed.

The students stand n a pier(码头) ver the Harlem River in New Yrk City.They stare dwn int the brwn water.Their teacher,Mr.Rdman,pulls a lng rpe ut f the river.Fastened t the end f the rpe is a metal cage and inside are ysters(牡蛎).Taking turns,the students measure all the ysters,and then cmpare ntes.The biggest yster is ver 2 inches lng,much bigger than a healthy size fr its age! They als measure the level f xygen.As mre ysters grw,the water shuld becme clearer and hld mre xygen.Als,ther animals shuld mve in.
Oysters are sft-bdied animals,and share the underwater cmmunity with plants,fish,and ther life.They are fd fr crabs and ther animals.As new ysters grw,they attach their shells t lder nes,frming big reefs with many small spaces where ther animals live.Oysters eat algae(藻类).If algae grw t fast,they can decrease xygen frm the water—and even fish need xygen t breathe!
But what happened t the ysters 100 years ag in New Yrk Harbr?Befre then,lts f ysters lived in these waters.They were shipped t restaurants arund the wrld.By the early 1900s,peple were eating them faster than they culd grw.Pllutin was puring int the waters.The harbr became seriusly plluted.Since the 1970s,new laws have helped reduce pisnus waste.Sme fish started t swim thrugh again.But ysters were still missing—until recently.
The Billin Oyster Prject began in 2014 t help bring ysters back t New Yrk Harbr.The prject has recruited(招募) mre than 6,500 students at mre than 100 middle schls and high schls t help grw,distribute,and study the ysters.
Finally,the students put the ysters back in the lwers the cage int the river.In a few mnths,they will check the cage again.When the ysters are big enugh,they will be mved t jin a healthy reef in the middle f the harbr.

Ⅰ.【语篇解读】本文是一篇说明文。文章主要介绍了科学家们发现了世界上已知的最大的海草场。他们借助一些不寻常的助手拍摄的视频来做到这一点。这项工作应该有助于保护海草,同时也展示了一种探索海洋的强大方式。
1.A 细节理解题。根据第二段中的“Theyhelpinthefightagainsttheclimatecrisis.That’sbecausetheystrehugeamuntsfcarbn—themajrsurcefglbalwarming.Damagingtheseseagrassmeadwscanreleasethispllutantagain,makingthingswrse.”可知,海草草场迫切需要保护是因为破坏它们将加剧气候危机。
2.C 细节理解题。根据第四段中的“Between2016and2020,theresearchersattachedcamerasandthertrackerstthefinsfseventigersharks,,thertlswereused,includingsatelliteimages,aswellasimagestakenbydiversandbats.”可知,虎鲨是通过随身携带记录设备帮助科学研究的。故选C项。
3.D 推理判断题。根据最后一段内容可推知,文章中研究的亮点是不同寻常的研究辅助对象——虎鲨。
4.D 标题归纳题。根据文章大意,尤其是第一段和第二段中的“Asashelterfrmanyseacreatures,seagrassisaflweringplantthatnrmallygrwsinshallwwatersnearcasts.Theygrwinthickfields,knwnasseagrassmeadws”可知,文章主要讲述了科学家们发现了世界上已知的最大的海草场。他们借助一些不寻常的助手拍摄的视频来做到这一点。这项工作应该有助于保护海草,同时也展示了一种探索海洋的强大方式。故文章最好的标题是“由自然探险家测量的海洋肺”。
【语篇解读】本文是一篇说明文。文章讲述了学生通过在码头进行测量获知,消失已久的牡蛎再次出现。同时介绍了牡蛎在水中起到的作用以及解释了牡蛎在纽约港消失的原因。最后学生们通过研究发现,这些大自然的助手正在回归。
5.A 细节理解题。根据第一段中的“,Mr.Rdman,pullsalngrpeutftheriver.”以及“Theyalsmeasurethelevelfxygen.Asmreystersgrw,thewatershuldbecmeclearerandhldmrexygen.”可知,通过学生们在码头所做的各种测量可知,学生们在进行研究。
6.D 段落大意题。根据第二段中的“Oysterseatalgae.Ifalgaegrwtfast,theycandecreasexygenfrmthewater—andevenfishneedxygentbreathe!”可知,本段主要介绍了牡蛎吃海藻,并且有利于水中氧气的产生,即阐述了牡蛎在水中所起到的作用。
7.C 推理判断题。根据第三段中的“,—untilrecently.”可知,受到污染的影响,牡蛎在纽约港仍然是不见踪影的。
8.C 标题归纳题。通读全文,文章讲述了学生通过在码头进行测量获知,消失已久的牡蛎再次出现。同时根据第二段中的“Oysterseatalgae.Ifalgaegrwtfast,theycandecreasexygenfrmthewater—andevenfishneedxygentbreathe!”可知,此处主要介绍了牡蛎吃海藻,并且有利于水中氧气的产生,因此C项“Nature’sHelpfulCrewBrughtBack(大自然的帮手回来了)”适合作文章标题。

7.A 根据上文“Ialslearnedthat...”可知,“我”认识到在付出的同时自己也会受益,这就是“我”通过养狗学习到的一个经验,这个经验一直伴随着“我”的成长。
8.B 文章开头讲父亲特别讨厌狗,反对养狗,结合本段末“HeevenmadechewtysfrChiptplaywith.”可知,爸爸对小狗的态度转变了,缓和了对小狗的态度。
9.A 根据上一段讲小狗在门口迎接主人归来,主人伤心时安慰主人,和本段中讲爸爸也喜欢上它,可推知,小狗讨人喜欢。
10.C 下文“HeevenmadechewtysfrChiptplaywith.”说明爸爸也开始宠爱小狗,结合副词“even”可推知,爸爸是第一个让小狗坐沙发的人。
11.C 根据句中“brughtustgether”和下文“insteadfescapingturbedrmsasbefre”可知,小狗改变了所有人的习惯,让一家人聚在了一起。
12.B 根据句中“review”可知,是复习以前学的把戏。
