1.China’smannedsubmersibleFendouzhesuccessfullycompleteda10,909-metrediveintotheChallengerDeepchasmintheMarianaTrenchonNov.10,2020.

译文:2020年11月10日,中国“奋斗者”号载人潜水器成功坐底位于马里亚纳海沟的“挑战者深渊”,深度10909米。

分析:句子主语是China’smannedsubmersibleFendouzhe,谓语是completed,宾语是a10,909-metredive,地点状语和时间状语是intotheChallengerDeepchasmintheMarianaTrenchonNov.10,2020。;2.Whileitischallengingtomakeamannedsubmersiblethatcansafelydivetothedeepestpartoftheocean,wherethewaterpressureis1,100timesgreaterthanatmosphericpressure,itisevenmoredifficulttolivestreamvideofromsuchdepths.

译文:虽然让载人潜水器安全坐底海洋最深处具有挑战性,这里水压是大气中压力的1100倍,但是从这么深的地方视频直播就更加困难了。

分析:这是一个主从复合句,while引导一个让步状语从句,在这个从句中,where引导定语从句修饰thedeepestpartoftheocean。;探究思辨
