语篇解读:
本文是一篇说明文,介绍了“天琴一号”卫星上应用的无拖拽控制技术,该技术体现了中国科技的进步。
1.Whatdoestheunderlinedword“it”inParagraph2referto?
A.Gravitationalwavedetection.
B.Dragfreecontroltechnology.
C.Acertainspacesatellite.
D.Sunlightpressure.
解析:
选C 代词指代题。
根据第二段中的“Dragfreecontroltechnologyblocksforcesthataffectasatellite,excludinggravity,soitcanremainstable”可知,无拖拽控制技术可以阻止除引力外影响卫星的力,因此卫星可以保持稳定,故画线词it指的是“卫星”,故C项正确。
2.WhatdoestheauthorintendtotellusinParagraph3?
A.Ourtechnologyishighlyadvanced.
B.TheTianqin1iswidelyknownworldwide.
C.TheLISAsatelliteisatotalsuccess.
D.TheTianqin1'saccelerationisincreased.
解析:
选A 推理判断题。
第三段前半部分说中国的新技术比欧洲的先进,无拖拽控制技术使得外力对加速度的影响比打哈欠给人带来的加速度的影响还要小,后半部分强调这一技术优于国际著名的LISA卫星应用的技术,故本段的主要目的是向读者展示中国先进的科技,故A项正确。
3.WhatisTRUEabouttheTianqin1?
A.Itwassentintospacein2015.
B.Itguaranteesgreateraccuracywhenworking.
C.Itstillneedstimetoremainstable.
D.Itcancreategravitationalwaves.
解析:
选B 推理判断题。
根据第三段最后两句可知,中国这一技术(无拖拽控制技术)将外力引起的卫星移位控制在了30纳米,优于国际著名的LISA卫星的40纳米。
由此可推知“天琴一号”在工作时可以保证较高的准确性。
故B项正确。
4.Whereisthispassageprobablytakenfrom?
A.Anartmagazine. B.Atravelbrochure.
C.Amathematicessay.D.Asciencejournal.
解析:
选D 文章出处题。
根据全文内容可知,本文主要介绍了中国航天事业上的科技进步,故本文很有可能选自科学杂志,故D项正确。
