ThefirstlabmoduleisWentianwhichisalreadydockedwiththeTianhecoremodule.ThethreemoduleswillformaT-shapedcomplexinspace.(梦天号是第二个实验舱，也是我国空间站的最后一个主要组成部分。第一个实验舱是“问天”号，它已经与天河号核心舱对接。这三个模块将在太空中形成一个t形的综合体)”可知，梦天号是第三个主要组成部分，所以A项错误，第三段中“Mengtianwillalsoactasabackupforthecoremodulewhenitisundergoingmaintenance.(“梦天”还将在核心模块进行维护时充当备用模块)”可知，它在空间站的维护中起着重要的作用，所以B项正确，“WhileWentianisusedforbiologicalandspacelifescienceprojects,suchasobservingthegrowthofvariouskindsofplants,animalsandmicrobesinspace,Mengtianwillbeusedforin-orbitexperimentsdedicatedtophysicsandmaterialsciencesandwillfocusonmicro-gravityexperiments.(“问天”号将用于生物和空间生命科学项目，如观察各种植物、动物和微生物在太空中的生长，而“梦天”号将用于物理和材料科学的在轨实验，并将重点放在微重力实验上)”，可知，“梦天”号将用于物理和材料科学的在轨实验，所以D项错误，C项文中未提及错误。故选B项。2．主旨大意题。根据第三段中“Mengtianweighsabout23tons.Itis17.9meterslongandhasamaximumdiameterof4.2meters.

Itcanbefurthersubdividedintowork,resource,payloadandcargoairlockcabins.WhileWentianisusedforbiologicalandspacelifescienceprojects,suchasobservingthegrowthofvariouskindsofplants,animalsandmicrobesinspace,Mengtianwillbeusedforin-orbitexperimentsdedicatedtophysicsandmaterialsciencesandwillfocusonmicro-gravityexperiments.

Mengtianwillalsoactasabackupforthecoremodulewhenitisundergoingmaintenance.

AndwithMengtianinplace,thespacestationwillbeabletoholdmoretaikonauts.(梦天重约23吨。它长17.9米，最大直径4.2米。它可以进一步细分为工作舱、资源舱、有效载荷舱和货物气闸舱。“问天”号将用于生物和空间生命科学项目，如观察各种植物、动物和微生物在太空中的生长，而“梦天”号将用于物理和材料科学的在轨实验，并将重点放在微重力实验上。“梦天”还将在核心模块进行维护时充当备用模块。随着“梦天”的就位，空间站将能够容纳更多的宇航员)”可知，第三段要告诉我们关于空间站的应用。故选A项。3．细节理解题。根据倒数第二段中“Andin2023,Chinawillalsodevelopnext-generationcarrierrocketsandcrewedspaceshipstosignificantlyenhanceitsspaceprogram’soveralltechnologicalcapabilities.(2023年，中国还将开发下一代运载火箭和载人飞船，以显著提高其太空计划的整体技术能力)”可知，中国太空计划的下一步是开发下一代运载火箭和载人宇宙飞船。故选D项。4．推理判断题。根据最后一段“Chinahasexpressedonmanyoccasionsthatitacceptsinternationalcooperationandforeignastronautstoconductresearchaboarditsspacestation.

So,let’sexpecttounlockmoremysteriesoftheuniversethroughjointglobalefforts.(中国曾多次表示，接受国际合作，接受外国航天员到中国空间站进行科研工作。因此，让我们期待通过全球的共同努力来解开更多的宇宙之谜)”可知，中国希望与其他国家共同探索太空。故
