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 week’s $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 Amazon’s 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 don’t 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 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 museum in the Netherlands is trying to show visitors more of the objects it has and bring them more excitement.It is using an augmented reality（增强现实）device made by Microsoft to reach its goal.However,the use of this high-technology device started with a basic problem.

The Dutch National Museum of Antiquities does not have enough space to put all of its artifacts（人工制品）on display.So,the museum asked experts at Delft University of Science and Technology to find a way to let more visitors—especially young people—experience what the museum has to offer.

The experts used the Hololens（全息透镜）.It is a computer that shows visitors holograms,or virtual pictures that appear to have three dimensions.

Annelies Maltha,a researcher at the University,says that almost 80 percent of the artifacts at the museum are not shown to the public."So by using the Hololens,"she adds,"people can virtually visit the exhibit and see so much more."

The Dutch National Museum has artifacts like the Egyptian Temple of Teffeh.The structure was reconstructed inside the museum in 1971.It is not currently available to the public.

"The Hololens enables you to have augmented reality,instead of virtual reality,which means you can still see the temple,you can still feel the ancient vibe（氛围）around you,so to speak."The augmented reality technology gives visitors the ability to interact with their surroundings.

The researchers are using the Hololens to make three dimensional images of every room in the temple.Erik Hoglund,another researcher,explains that his team can create 3D models and add different images,movies,or animations.The effect is to make visitors feel like they are interacting with the temple.

The Hololens program is still being developed.But museum officials hope that,in the future,the Hololens will serve as a tour guide for exhibits that have been hidden from public view.

1.What does the underlined part "its goal" in Paragraph 1 mean?

A. The experience of excitement.

B. The solving of the basic problem.

C. The showing of more museum objects.

D. The use of the augmented reality device.

2.What can be learnt about the augmented reality device?

A. It has been widely applied to museums.

B. It is what we call virtual reality.

C. It is developed by Microsoft.

D. It has many hidden dangers.

3.Which of the following statements about the Hololens is TRUE?

A. It makes interactions possible.

B. It gives the museum much more space.

C. It enables visitors to have virtual reality.

D. It is a must-have item for the common people.

4.What would happen if the technology were to be applied in the museums?

a.More young people would be attracted to the museums.

b.More items of the museums would be on display.

c.People would travel back to ancient times.

d.Fewer guides would be needed.

A. abd　　 B. abc

Animals are not always animals. Some of them will try to cheat or cow some others in the way the human beings often do. Here is a fairy tale from Aesop for you to enjoy.

To carry out her design, she climbed to the nest of the eagle, saying, "Destruction is preparing for you and for me too, unfortunately. The wild pig, whom you see daily digging up the earth, wishes to uproot the tree, so she may on its fall seize our families as food for her young."

Having thus frightened the eagle out of her senses, she crept down to the cave of the pig, saying, "Your children are in great danger, for as soon as you go out to find food, the eagle is prepared to jump upon one of your little pigs."

Having filled these fears into the pig, she went and pretended to hide herself in the hollow of the tree. When night came she went out silently and obtained food for herself and her children, but pretending to be afraid, she kept a lookout all through the day. Meanwhile, the eagle, full of fear of the pig, sat still on the branches, and the pig, terrified by the eagle, did not dare to go out from her cave. Thus they both, along with their families, starved from hunger, and afforded good food for the cat and her children.

B. By cheating both the eagle and the pig.

C. By waiting and catching the chance.

D. By fighting against the eagle and the pig.
