Ⅰ.阅读理解僭越
(2016·苏锡常镇三模)
Computer power is moving into the “cloud”—networks of data centres that u the Internet to supply all kinds of rvices，from email and social networks to data storage and analysis.
The ri of cloud computing is rapid and causing huge changes in the tech industry.The old guard is suffering：this week’s 67 billion merger(合并) between Dell and EMC，makers of computers and storage devices respectively(分别地)，was a marriage forced by the ri of the cloud.Disruptive(捣乱的) newcomers are blooming：if Amazon’s cloudcomputing unit were a standalone public company，it would probably be worth almost as much as Dell and EMC combined.
The gains for customers have been equally dramatic.Compared with older IT systems，cloud computing is often much cheaper.It adds tremendous flexibility：firms that need more computing capacity no longer have to spend weeks adding new rvers and installing software.In the cloud they can get hold of it in minutes.Their applications can be updated continually，rather than just every few months.Individual urs can reach their e
mails，files and photos from any device.And cloud rvices also tend to be more cure，since providers know better than their customers how to protect their computing systems against hackers.
But cloud computing makes one problem wor.In the old IT world，once a firm or a consumer had decided on an operating system or databa，it was difficult and costly to switch to another.In the cloud this “lockin” is even wor.Cloud providers go to great lengths to make it easy to upload data.They accumulate huge amounts of complex information，which cannot easily be moved to an alternative provider.
Cloud firms also create a world of interconnected rvices，software and devices，which is convenient but only for as long as you don’t venture(冒险) outside their univer.Being locked in to a provider is risky.Firms can start to tighten the screws by increasing prices.If a cloud provider goes bust(破产)，its customers may have trouble getting back their data.
The risks have already caud a debate about whether the cloud needs stricter regulati
on.Some European politicians want to force cloud providers to ensure that data can be moved between them.That is too heavyhanded，becau strict rules will inhibit(阻碍) innovation in what is still a young industry.The history of computing suggests that common standards may well appear naturally in respon to customers’ demands—just as in personal computers，where it is now much easier to u the same files on different systems.
In the meantime，a few commonn measures can reduce the risk of lockin.Firms that u more than one cloud provider to host their data are less affected.So are tho that keep their most important information in their own data centres.Consumers can take precautions，too.Some rvices are better than others at enabling urs to move data between providers(Google does well on this score)．Cloud computing promis its urs many benefits，but don’t mistake it for some sort of digital heaven.
1．The author takes “the merger between Dell and EMC” for example to show ________.
A．the influence of cloud computing on computer and storage device makers
B．the mirable sufferings of old computer companies
自我管理技能C．the rapid development of new computer companies
D．the interaction between old companies and newcomers
