冲呀呀呀呀呀呀呀呀

Passage1
主旨：主体是围绕最近很火的Clubhouse，最近的热度很高，风投们对它的看法，以及对未来app发展所面临的竞争与风险；如果能保持住将会成为下一个Twitter。

结构：虽然比political的文章更接地气，但是不查单词的情况下，感觉结构就很松散，人名又很多；

1-3：主要围绕Clubhouse最近的热度，登顶APP榜首，Musk和VT在上面的对话引入了很多流量；
4-20：风投对app热度的评价和分析
21-26：主要聚焦在对Clubhouse未来发展的探讨，是选择继续邀请制还是面向大众，以及来自互联网巨头的竞争风险；

生词:
viral病毒性的；boon福利；fused capital with content creation；looming逼近；ephemeral短暂的；be wary of持谨慎态度；spurt迸发；avid热心的；void空白的；impromptu即兴的；backdrop背景音乐

好句：
Clubhouse, the fastest-growing social media app in the world, has a familiar group to thank for its recent success: a tight-knit band of Silicon Valley insiders who have willed the company into virality.

Late last month, thousands of people tuned into a discussion between Elon Musk and Robinhood chief executive Vlad Tenev about the brokerage app’s controversial decision to limit trading in GameStop and other popular stocks.

The company has not settled on a business model, though its founders have discussed subscriptions, a move that could deter some people but also appeal to privacy-conscious users who are wary of ad-based networks.
此举会让一些人望而却步，但同时也会吸引到那些注重隐私，对广告望而却步的用户。

文章1:Clubhouse能够成为主流App吗？
1，从一月开始，clubhouse攀登成为ranking app
2，However ，Clubhouse存在技术问题。
3，通过对Paul Davision和Rohan Seth两位创始者的采访表明，扩张将是下一个面临的问题。同样Clubhouse面临更大社交平台的竞争。
4，总结：Clubhouse如果继续保持增长，那就是下一个Twitter。
生词：brokerage,boon pandemic exquisitely undeterred
文章2:美国经济增长
1，过去十年认为Input作为经济增长的主要资源，但是1950‘s的尝试否定了这一点。
2，RMS建立一个理论：经济增长等于Capital和Labor （取决于the value of product）增长，和第三个变量productivity的增长。最早认为这三个变量都是独立的，互不影响。其实capital会影响productivity的增长。
3，MA做了一个类似研究，15%的经济增长归因于input的增长，Capita和Labor的增长非常efficient，而不少简单影响Input的增长。

作者提出讨论-是否clubhouse能成为主流媒体

分论点
1.介绍了什么是clubhouse，以及其之前流量暴增的原因。
2.app的流量暴增，提高了公司的估值，为公司发展带来资金
3.然而流量暴涨也让这个app暴露了一些缺陷
4.公司表示会积极优化APP，这个APP的流量也引起了马克的入驻，下个突破点是“人传人”，APP的商业模式尚未确定，带来的结果有两面性。
5.然而其他主流媒体公司也开始进行模仿竞争，挑战不断
6.clubhouse 能否保持流量和用户留存率遭到质疑
7. 背后老板表示在APP没火之前，他整副身价都丢进去了，所以他非常有信心成为下一个推特

中心大意
作者引用多个经济学家对国家经济增长的衡量方式，讨论对增长有影响的因素

分论点

2.引用Solow的观点，经济增长仅仅取决于资金和人力投入的增长；
3.Solow的研究成果有85%符合了经济发展的情况，获得诺贝尔奖
4.MA引用这个理论，发现只有15%的增长能归结于更多投入的利用，得出国家的长期项目更应该重视利用率而不是单纯的投入量

中心大意
讨论了经济增长与额外投入间的关系。

分论点
1.一国经济可以通过增加生产要素或提高生产力得以增长。经济学家们大多认为追加投入是经济增长的主要来源，但最开始的学者否认此观点。
2~3 Solow认为经济增长=资本投入增长率+劳动投入增长率+生产要素的增长，且三者互不影响。 美国85%的经济增长来源于生产力或科技的进步。
4 MA得出同样结论，但更谨慎地解释了85%的剩余。在早期分析中，达成一致的是：长期经济增长是由于高效使用资本和劳动力，而非简单地增加投入。

生词
Circumspect adj. 小心谨慎的，考虑周到的，慎重的

A representative for Clubhouse declined to make founders Paul Davison and Rohan Seth available for an interview.

Clubhouse, which is still invite-only and requires an iPhone to access it, has been downloaded about 3.4m times since it first opened to users early last year, according to the data provider App Annie.

American Economic Growth
阅读时间:4‘16
总结时间: 35’
总时间: 40’

文章中心大意
Background: two factors related to a country’s economy growth: production and productivity. => Traditional view: the use of additional inputs as the main source of economic growth => however, researchers found that only about 15 percent of the growth could be traced to the use of more inputs and it seems that additional inputs has little impact on economic growth

每段段落大意
1，A country’s economy growth is associated with more factors of  production , such as labor and capital , and productivity. The traditional view is to add other inputs as the main source of economic growth. But the view was refuted by attempts in 1950’s.
2, Robert.M. Solow formulated the basic relation: an economy’s growth is the sum of the growths in the inputs of capital and labor as well as a third variable that represents the increases in factor productivity
3, The three variables are assumed to be independent in the original basic relation. In this way Solow and others found that around 85 percent of economy growth attributes to increases in productivity or technological change.
4, Moses had applied a similar technique and had found that simply increasing more inputs has little impact on a country’s economy growth

印象深刻的句子：
An economy’s growth is simply the sum of the growths in the inputs of capital and labor, each weighted by a coefficient reflecting its average contribution to the value of products , as well as a third variable that represents the increases in factor productivity.
