Computer power is moving into the “cloud...

Computer power is moving into the cloud—networks of data centres that use the Internet to supply all kinds of services, from e-mail and social networks to data storage and analysis.

The rise of cloud computing is rapid and causing huge changes in the tech industry. The old guard is suffering: this weeks $67 billion merger (合并) between Dell and EMC, makers of computers and storage devices respectively (分别), was a marriage forced by the rise of the cloud. Disruptive (捣乱的) newcomers are blooming: if Amazons cloud-computing unit were a stand-alone 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 servers 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 users can reach their e-mails, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their computing systems against hackers.

But cloud computing makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this lock-in is even worse. 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 services, software and devices, which is convenient but only for as long as you dont venture (冒险) outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust (崩溃), its customers may have trouble getting back their data.

These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavy-handed, because 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 response to customers demands—just as in personal computers, where it is now much easier to use the same files on different systems.

In the meantime, a few commonsense measures can reduce the risk of lock-in. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in their own data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud computing promises its users many benefits, but dont mistake it for some sort of digital heaven.

请认真阅读下面短文, 从短文后各题所给的A、B、C、D四个选项中, 选出最佳选项, 并在答题纸上将该项涂黑。

How many licks (舔) does it take to get to the center of a Tootsie Pop (棒棒糖)?

The first time I heard this in the Tootsie Pop commercial, I was five years old. I immediately started _________  and counting. After about two hundred licks or so, I stopped. The _________ of the chewy center had proven to be too great, and I   _________  my way through the hard shell (外壳) to the very center. Besides, I _________ knew how many licks it took to get to the center—three. That’s how many licks it took the owl (猫头鹰) in the commercial to get to the center, so that, to me, was the _________ answer.

In high school, I held to the Tootsie Pop _________  . To me, the answer was still always three licks.

In my freshman year, I joined the Model United Nations _________  in my school. The Chair position had   _________  the center of the Tootsie Pop and my _________  had become various other students. The first so-called “owl” was Eric who had luckily _________  the prestigious (声望高的) Chair position. So, I decided, _________ Eric reached the center in only one lick, that’s how many licks it should take me. I went to the tryouts with a view to obtaining the position but _________  .

At the end of my sophomore (高二) year, a new owl named Iris had _________  achieved the chair position after trying twice. I began working hard again. But then again, I did not make a _________  of it.

Now, slightly frustrated after _________ two owls, I found a new owl, Evan. It had taken him three licks to get to the “center”. Three was all I could _________. It was widely known that senior year was the _________  year to become Chair. I thought about _________ the program, but on second thoughts, I decided to continue.

Eleven years later, I visited the official Tootsie Pop website to find the real answer to the question that had _________ me my entire high school life. I finally understood. However many licks it takes to get to the center of the Tootsie Pop depends on however many licks I _________  to take—not how many the other owls take.
