31.What would be the suitable title for this passage?A.What Are Diamond Planets Like?B.Why Are Diamonds on Earth So Valuable?C.Places Where Diamonds Are As Common As RocksD.The Universe Maybe Has Planets Made of Diamonds0The biggest television drama has been the story of how people watch it.Ten years agonearly nine out of ten American households subscribed to cable(有线电视)or satellite TV.Today little more than half do.The collapse of pay-TV,with the advance in onlinestreaming,has shifted the television industry,forcing studios to rethink their businessmodel.The pace of tearing up the contracts is only increasing.But not everywhere.Europeans are signing up for cable and satellite TV in greater numbers than ever.Why has American media's trend missed Europe?One reason is the price.America'scable industry looks more competitive:the largest telecommunications company has only aquarter of the market.But it is highly regionalised,so most homes have few options.Theresult is an average monthly cable bill of nearly $100.British homes pay less than half theprice.Also,American cable is running out of shows as studios move their best ones to theirown streaming platforms.In Europe,where some streaming platforms have yet to belaunched,pay-TV firms keep the rights to many of the most popular titles.Britons seekingthe third season of Succession,for instance,must go to the satellite TV,since there's noother choice.The last reason is that American streaming platforms have partnered with pay-TV firmsin Europe rather than competing with them.In the race for subscribers,the quickest way forstreaming platforms to expand in Europe is to join forces with satellite and cable companies.They are the ones with access to consumers and the ability to handle local marketing and adsales.Will the trend eventually cross the Atlantic?As long as studios continue to license localcompanies to broadcast their programs,consumers will have every reason to stick with pay-TV.In the long run,though,studios would rather bring viewers onto their own platforms.And the condition could be different.32.What does the underlined phrase in the first paragraph mean?A.Refusing online streaming.B.Changing the TV industry.C.Breaking promises to users.D.Stopping using pay-TV.33.Which aspect of pay-TV is mainly discussed in paragraph 3?A.Low price.B.Its convenience.C.Its content.D.Related technology.34.What is the way for streaming platforms to gain European subscribers quickly?A.Cutting down on their charges.B.Cooperating with local pay-TV firms.C.Setting up satellite and cable companies.D.Investigating European consumers'preference.英语试题（雅礼版）第6页（共10页）
