1Sir John Reith said that it would end "isolation of the spirit" and rejoiced: "It does not matter how many thousands may be listening, there is always enough for others... the genius and the fool, the wealthy and the poor listen simultaneously."
主干主语：Sir John Reith；谓语：said ... and rejoiced（并列谓语）；宾语：that 从句及直接引语
结构主句含两个并列谓语 said 和 rejoiced；said 后接 that 宾语从句；冒号后引语中 "It does not matter how many thousands may be listening" 是 it 作形式主语、how many 引导的从句作真正主语的让步句式，意为"无论多少人在听"；句末 "the genius and the fool, the wealthy and the poor" 用定冠词加形容词表一类人，作 listen 的主语。
译文约翰·里斯爵士说，广播将终结"精神的隔绝"，并欣喜地表示："无论有多少人在收听，节目对其他人来说永远够用……天才与愚人、富人与穷人，都在同时聆听。"
考点It does not matter + 疑问词从句：it 为形式主语，表"无论……都无所谓" · the + 形容词（the wealthy / the poor）表示一类人，作主语时谓语用复数
2Opening this week, a book and exhibition curated by Beaty Rubens at the Bodleian in Oxford records how radio changed everyday life from 1922 to 1939.
主干主语：a book and exhibition；谓语：records；宾语：how 引导的宾语从句
结构句首 "Opening this week" 是现在分词短语作时间状语；主语 "a book and exhibition" 后接过去分词短语 "curated by Beaty Rubens at the Bodleian in Oxford" 作后置定语；谓语 records 后接 how 引导的宾语从句。注意主语虽由 and 连接，但指同一项目，谓语用单数 records。
译文本周在牛津博德利图书馆开幕的一个由贝蒂·鲁本斯策划的书籍与展览，记录了1922至1939年间广播如何改变了人们的日常生活。
考点过去分词 curated by... 作后置定语，相当于定语从句 which is curated by... · and 连接的两部分指同一事物时，谓语动词用单数
3True: for more than 80 pre-digital years, linear speech broadcasting brought the gift of serendipity, random enlivenings of a car journey or dull manual task.
主干主语：linear speech broadcasting；谓语：brought；宾语：the gift of serendipity
结构"True" 是独立评注，承上启下；"for more than 80 pre-digital years" 为时间状语；句末 "random enlivenings of a car journey or dull manual task" 是 serendipity 的同位语，对其进行解释说明，其中 enlivenings 后接 of 短语作定语。serendipity（意外发现美好事物的运气）是考研高频难词。
译文确实如此：在数字时代到来前的80多年里，线性语音广播带来了意外之喜——它能在驾车途中或干枯燥体力活时，随机给人带来些许生气与乐趣。
考点同位语对前面抽象名词 serendipity 作具体解释，理解时可借助破折号"即、也就是" · serendipity 意为"意外收获、机缘巧合"，属高频难词
4And while it is wonderful to take a walk with anything in your headphones, infinite choice encourages us to shrink into niche interests and sympathetic beliefs.
主干主语：infinite choice；谓语：encourages；宾语：us；宾补：to shrink into niche interests and sympathetic beliefs
结构"while it is wonderful to take a walk..." 是 while 引导的让步状语从句，意为"尽管"，从句中 it 为形式主语，真正主语是不定式 to take a walk；主句谓语 encourages 后接不定式复合结构 encourage sb. to do sth.；"shrink into" 意为"退缩进、局限于"。
译文尽管戴着耳机随便听点什么去散步很惬意，但无限的选择会诱使我们退缩进自己狭隘的兴趣和彼此投合的观念之中。
考点while 置于句首常表让步，译"尽管、虽然"，而非"当……时" · encourage sb. to do sth. 不定式作宾语补足语
5Today we worry about the isolating culture of smartphone-staring and selfie-vanity, but already in 1939 there was that lady regretting how, when all her street got wirelesses, it lost the neighbourly habit of "talking on the brush handle".
主干分句一：主语 we，谓语 worry about，宾语 the isolating culture；分句二：there be 句型，主语 that lady，后接现在分词 regretting 作定语
结构but 连接两个并列分句。第二分句是 there be 句型，"regretting how..." 是现在分词短语作后置定语修饰 that lady；regretting 后接 how 引导的宾语从句，该从句中又嵌套 when 引导的时间状语从句 "when all her street got wirelesses"，宾语从句主干为 it lost the neighbourly habit。多层嵌套是本句难点。
译文如今我们担忧盯手机和自拍虚荣造成的孤立文化，但其实早在1939年，就有那位女士感叹：当整条街的人家都装上了收音机，街坊邻里"倚着扫帚把闲聊"的习惯便消失了。
考点there be 句型后接现在分词短语作后置定语，相当于 who regretted... · 宾语从句中嵌套时间状语从句，翻译时先处理 when 从句再说主句
