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. the influence of cloud computing on computer and storage device makers

B. the miserable sufferings of old computer companies

C. it may make it difficult for customers to recover their data

D. it will discourage an argument about stricter rules

4.It can be inferred from the last two paragraphs that ________.

A. the European politicians’ advice is perfect

B. customers’ demands play a role in setting standards

C. lock-in is caused by firms’ storing information in their own centres

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

With the development of the Internet and the popularization of computers, shopping on the Internet has become a common place in our life. Here consumers can buy almost everything they need.

Shopping on the Internet has a lot of advantages, of which the most important is perhaps its convenience. People don’t have to waste a lot of their energy and precious time to go from one shop to another to choose the commodities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person. The goods come in all shapes, sizes and colors on the Internet. The commodities they order will be delivered to them promptly.

However, shopping on the Internet also has its disadvantages. The first disadvantage is that the consumers can’t see the goods or try them on personally. Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered. They will never deliver anything to you after they get the money from you. Once cheated, you will find that you have nowhere to go to complain.

1. 以约30个词概括短文的要点;

2. 然后以约120个词以”网上购物”为主题发表看法,并包括以下要点:

(1) 你认为网上购物的最大优点是什么;

(2) 描述你或你的朋友或同学网上购物的体验;

(3) 你对网上购物有什么建议.

1. 可以使用事例或其他论述方法支持你的观点, 也可以参照阅读材料的内容但不能直接引用原文中的句子;

2. 标题自拟.

Knowledge Management

Thanks to advances in computers, modem means of communication and the Internet, information has become easier to obtain. It is now much more significant in our daily lives.

Organizations believe that having better information leads to better decision making. 1. Too much information makes it difficult to decide which pieces of information are useful in making the best decisions and which are not. Selecting and obtaining the right information and using it well can give an organisation a competitive advantage. This is how the field of “knowledge management” ,or KM, arose.

2. In fact, we need to distinguish between data, information and knowledge. Some concrete examples can help. Looking at the daily transactions of a shop, I may see that 12 units of product X have been sold this month—that is an interesting piece of data. 3. I can change this data into valuable information if I know that 20 units of product X were sold the previous month— this informs me that sales in that item have dropped. So data + context = information. Now, based on my years of experience working in the shop and my familiarity with my costumers, I can use my knowledge to decide whether I should order more of the same product or not.

4. The first is the activity of obtaining the best information. This often relies on technology, such as powerful computers, to filter or store information. 5. So, knowledge can flow easily through the organization. The other part is the more human side, which focuses on employees exploiting (利用)the information to create competitive advantage for the organization.

Companies that adopt KM strategies believe that they will achieve better results because they exploit the potential of both modem technological advances and good old-fashioned experience.

A.Therefore, KM can be divided into two parts.

B.It also relies on good networks of communication.

C.And it is being adopted by more and more businesses today.

D.In order to understand what KM is, it is necessary to define it.

E.But I cannot make a decision based on it because it lacks context.

F.My insight tells me that after a while my customers will go back to buying product X.

G.However, with greater access to information comes the problem of information overload.

You signed up for soccer, and played every game of the season. Sure, you're not the best player on the team, but most days you gave it your all. Do you deserve a trophy (奖杯)?

If the decision is up to Carol Dweck, the answer would likely be no. She's a psychology professor at Stanford University, California. She says a player doesn't have to be the best to get a trophy. But those who receive an award should have to work for it. She suggests trophies go to the most improved player, or the one who contributed most to the team spirit, as well as to those who play the best.

“The trophy has to stand for something，” Dweck told TFK. “If we give a trophy to everyone, then the award has no value.” Dweck argues that giving kids trophies for particular reasons, such as improving　 in a sport, teaches kids that adults value hard work and trying our best.

Others say that there's no harm in giving awards to all kids who play a sport, regardless of how they played or whether or not they improved.

“I think we should encourage kids' participation in sports，” says Kenneth Barish, a psychology professor at Weill Cornell Medical College,　 in New York City. “A trophy is one way to encourage kids' efforts.”

Barish argues that when we single_out only the best or even the most improved players with a trophy, we are teaching kids the wrong lesson. We are sending the message that winning is everything. “Winning is only part of the equation (等式)，” Barish told TFK. “Playing sports also teaches kids about teamwork and the importance of exercise.”

There will be plenty of opportunities for kids to learn about competition as they get older, says Barish. They'll soon realize that only one soccer team wins the World Cup and only one football team wins the Super Bowl. For now, he thinks there's nothing wrong with letting all kids who play a sport feel like winners. That means trophies for everyone.

1.According to Carol Dweck, which player should receive a trophy?

A．Tony, the most attractive player of the soccer team.

B．David, a soccer player who is both clever and funny.

C．Peter, who is ready to help his partners to score goals.

D．Jim, a soccer player who tries his best to win the game.

2.Which of the following statements would Kenneth Barish agree with?

A．There is no sense in giving a trophy to everyone.

B．Kids fond of playing sports should be rewarded.

C．Kids should be given trophies for trying their best.

D．It is necessary to encourage kids' participation in sports.

3.The underlined phrase “single out” in Paragraph 6 probably means “________”．

A．honour　　　　　 　 B．choose

C．value　 　　　　　　 D．stress

4.Which shows the correct structure of the text?

We are all busy talking about and using the Internet but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

At first the Internet was only used by the government, but in the early 1970s, universities, hospitals, and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet easier.

Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mails is more and more popular among young people.

The Internet has now become one of the most important parts of people’s life.

Nowadays along with the booming of computer science, computers are widely used here and there. People even can find computers in most classrooms. While teachers remain more or less the same, computers are doubling in speed and capability every four years. 1. As far as I am concerned, teachers still play a major role and are still of great importance.

2. However advanced they may be, computers are nothing more than human inventions programmed to perform certain tasks.

They are unable to deal with students with different background. Needless to say, a classroom is a place where individual attention and creativity matter most. Therefore, computers are no better than other tools used by teachers and couldn’t possibly make the roles played by them weaker.

In terms of accuracy and the amount of information, computers outshine humans. 3. Indeed, a good teacher organizes and inspires the students.

Besides, the interaction between students and teachers is vital for the learning. According to most education authorities, real learning occurs during the discussion and sharing of ideas with one’s teacher and classmates. Moreover, a teacher is there to monitor every slight change in students’ attitude, to respond to and encourage them whenever they show signs of frustration and impatience. 4.

Despite the increasing presence of computers inside classrooms, teachers are just as essential, if not more so, as instructors were in the past. 5.

A. It’s time that teachers should develop themselves.

B. Without this kind of interaction, education is unimaginable.

C. Advanced as computers may be, some teachers are less impatient.

D. But to make a good teacher means far more than being an encyclopedia (百科全书).

E. People can’t help wondering whether teachers are as important as they once were.

F. Some drawbacks make it impossible for computers to replace teachers in classrooms.

G. It is well known that computers are better at repetitive work but incapable of creative thinking.
