11月24日4时30分,我国在中国文昌航天发射场,用长征五号遥五运载火箭成功发射探月工程嫦娥五号探测器,火箭飞行约2200秒后,顺利将探测器送入预定轨道,开启我国首次地外天体采样返回之旅。#奇速英语时文阅读#英语时文阅读英语时文阅读:嫦娥五号发射成功英语时文阅读:嫦娥五号发射成功02:09来自奇速英语学堂ChinahaslaunchedamissiontotrytogetrocksamplesfromtheMoon.ItsroboticChang'e-5spacecraftdepartedtheWenchanglaunchcomplexonaLongMarch5rocketearlyonTuesdaymorninglocaltime,andifsuccessfulshouldreturntoEarthinmid-December.It'smorethan40yearssincetheAmericansandtheSovietsbroughthomelunarrockandsoilforanalysis.Chinaaimstobeonlythethirdcountrytoachievethisfeat,whichwillbeanextremelycomplexendeavour.It'samulti-stepprocessthatinvolvesanorbiter,alander-ascenderandfinallyareturncomponentthatusesacapsuletosurviveafastandhotentryintoEarth'satmosphereattheendofthemission.Butconfidenceshouldbehighafteraseriesoflunarmissionsthatstartedjustoveradecadeagowithacouplesatellites.Thesewerefollowedupbylander-rovercombinations—withthemostrecent,Chang'e-4,makingasofttouchdownontheMoon'sfarside,somethingnonationhadpreviouslyaccomplished.

嫦娥五号将把目标锁定在一个名为MonsRümker的附近,这是一个高火山杂岩,位于一个被称为大洋洲Procellarum的地区。与美国阿波罗宇航员和苏联月球机器人取样的岩石相比,这个地点的岩石被认为是非常年轻的。这将给科学家们提供另一个数据点,来说明他们用来对太阳系内部事件进行年龄测定的方法。当嫦娥五号到达月球时,它将进入轨道。着陆器将分离并进行动力下降。一旦降落,仪器将在获取表面材料之前对周围环境进行特征描述。着陆器也有钻入土壤的能力。一个上升的飞行器将携带样本返回与轨道飞行器会合。一艘牧羊船将引导太空舱进入内蒙古上空的大气层。时文阅读习题1.Theunderlinedword“feat”inthefirstparagraphrefersto______.AgettingrocksamplesfromtheMoonBbuildingtheWenchanglaunchcomplexCgoingbeyondtheAmericansandtheSovietsDtakingamountsofthesoilfromtheSun2.WhatdidthespacecraftusetobearthehotairwhenreturningtotheEarth?AThelander.BThecapsule.CTheshepherdingcraft.DTheflyingsatellite.3.WhatisimportanceforChang'e-5togetrocksinMonsRümker?AItwillconfirmtheMoonisahighvolcaniccomplex.BItwillhelpknowtheexactageoftheinnerSolarSystem.CItwillprovetheUSApolloastronautsareactuallyright.DItwillshowtheSovietLunarobotsarebetterthanChina’s.4.WhatwillChang'e-5dobeforegettingthesamples?AItwillgobacktotheearthorbit.BItwilldrilldeepintothehardsoil.CItwillmakeclearofsurroundings.DItwillanalysethesoilofthemoon.文末导读:速领!小初高英语单词记忆:400张全彩卡片 高频词汇图解视频20个英语成绩怎么提升?每日一篇绕口令拒绝“死记硬背”!(含音频)超燃9分钟!衡水中学学生励志演讲:人间值得,未来可期!甘肃武威最大万人教培机构汇智阳光教育——加盟奇速英语!
