Unit3Underthesea也许这个星球上最未被开发的地区是海底，因为那里太深了，以至于我们无法详细研究。即使人们对海床进行商业开采，它仍是一个未知数。上层和中层水域的海洋生物都很容易记录，不过深海环境仍然深藏着很多秘密。探讨这些领域是困难的，因为海底深处有巨大的压力。目前我们还无法制造出能在深海正常工作的机器。当我们能够做到这一点时，我们将会发现一个全新的海洋世界。科学将揭示更多的深海秘密。参考词汇：未被开发的地区unexploredarea;详细研究searchindetail;商业开采businessexploration;上层和中层水域theupperandmiddlewaters【写作要求】只能用5个句子表达全部内容。Perhapsthemostunexploredareaonthisplanetisunderthedeepsea,whichwehaveneverbeento,becausetheyaretoodeepforustosearchindetail.Althoughwedohavebusinessexplorationoftheseabed,thedeepseaisstillunknown.Theenvironmentofdeepseacanstillkeepmanysecrets,thoughthemarinelifeoftheupperandmiddlewatersarefairlywellrecorded.Toexploretheseareaswithoutspecialmachinesisdifficultbecauseofthegreatpressuredeepdown.Whenthiscouldbedonewithmachines,scientistswillenableustofindoutmoresecretsofdeepseaoneday.1.adj.每年的n.年刊；年鉴2.n.目击者；证人；证据vt.目击3.vi.大叫；呼喊n.叫声；喊声4.vi.&n.暂停；中止5.n.协作；配合6.vt.拖；拉；扯7.n.深(度)；深处____________________________________________________________________________________________________________________________________________annualwitnessyellpauseteamworkdragdepth8.vt.催促；极力主张9.vt.放弃；遗弃；抛弃10.n.关系；血缘关系；交往11.vi.慢跑vt.轻推；轻撞12.n.网；网状物；网络13.n.目标；靶；受批评的对象14.vt.反射；思考vi.思考____________________________________________________________________________________________________________________________________________urgeabandonrelationshipjognettargetreflect15.adj.纯的；纯粹的；纯洁的16.adj.意识到的；知道的17.adj.生动的；鲜明的；鲜艳的18.adj.好的；整齐的19.adj.锐利的；锋利的；敏捷的20.vt.恐吓vi.受惊吓________________________________________________________________________________________________________________________pureawarevividneatsharpscare1.帮助(某人)摆脱困境或危难2.意识到3.吓死了4.在此期间，与此同时5.上下翻转6.拉回；撤回……________________________________________________________________________________________________________________________help(sb.)outbe/becomeawareof(be)scaredtodeathinthemeantimeupsidedownpull…back1.Aswedrewcloser,Icouldseeawhale________________(attack)byapackofaboutsixotherkillers.2.Therewasoneday________wewereoutinthebayduringahuntandJameswaswashedofftheboat.beingattackedwhen3.Theseawasroughthatdayand________wasdifficulttohandletheboat.4.TherewereothercreaturesthatIdidn'twanttogettoocloseto—aneelwithitsstrongsharpteeth,withonlyitshead________(show)fromahole,watchingforatastyfish(ormytastytoe！)．showingit1.witnessn.证人，目击者，证据vt.当场见到，目击Severedamagewitnessedthedestructiveforceofthestorm.严重的损害表明了暴风雨的破坏力。bearwitnessto为……作证awitnesstotheaccident事故的目击者witnessstand/box证人席根据汉语意思，完成英文句子(1)这个古老的礼堂见证过许多次典礼。Thisoldauditorium_______________________manyceremonies.(2)警察在呼吁曾目睹这次事故的司机协助。Policeareappealingtoanydriverwho______________________theaccident.haswitnessedwitnessed(3)他健康的身体证明了这种疗法是成功的。Hisgoodhealthis____________________thesuccessofthetreatment.awitnessto2.dragvt.拖，拉，扯n.拖，拉Themeetingdraggedonformorethantwohours.那个会议单...
