One of the biggest ideas in computer technology is cloud computing. The system is changing the way information is kept. It uses a group of computers or servers to store information instead of one. The data floats around like clouds instead of being saved on any computer. It means computers can be smaller than ever and store practically unlimited amounts of information. No longer are bulky computers needed because all the information is in the clouds.

So when will cloud computing start affecting the way you use computers? You may not have noticed, but it already has. Facebook, Amazon, Twitter and many other sites all run on cloud computing. Cloud computing is really useful. You can use it to access the same file at work at home or in other countries on different computers. There may even be environmental benefits, too. Gmail, which uses cloud computing, says that the system saves a lot of energy.

However, potential problems do exist such as losing information and not being able to access certain files when the internet is down. Also, some companies charge fees for their cloud computing services. Another major problem is security. If all your Information is out there in the cloud and not safely stored on your own computer or laptop, it may be possible for other people to access it. More and more of our personal information is in danger of being stolen. Therefore, it is important to be careful and to find ways of making the information secure.

More and more companies are starting up and offering cloud computing. Will the company be reliable? What will happen to your data if the company goes out of business? There are real worries. Even so, for those interested in computing technology, one thing is for certain ---the future in the clouds is going to be very exciting.

1.How does the author describe the data?

A.It needs only a single server.

B.It is a cloud floating around computers.

C.It makes computers become smaller.

D.It improves the computer’s function.

2.What can we learn from the passage?

A.Cloud computing will come into use soon.

B.Files will be entered when the Internet is down.

C.Personal information may be lost if not kept properly.

D.Companies will enjoy free cloud computing services.

3.What’s the author’s attitude towards cloud computing?

A.Worried. B.Positive.

C.Unclear. D.Cautious.

4.The purpose of the passage is 　　　　　　　　　　 .

A.to introduce cloud computing to us

B.to talk about the way computers change

C.to warn us to be careful to use computers

D.to tell us how to access information on other computers

With the arrival of the ABC(AI, big data, and cloud computing) era, AI is seemingly leading innovation(创新) trends. It’s believed that with the increasing application of deep learning algorithms(计算程序), AI will play a growing role in assisting human beings to complete various tasks in a range of fields.

Domestic internet giant Baidu recently announced that its public welfare Baidu Artificial Intelligence People Searching program successfully reunited more than 10, 000 lost people with their families over the past three years, which is a good example of how technology benefits people. Baidu launched this project using its artificial intelligence(AI) face-recognition technology.

Zhu Guang, senior vice president of Baidu, said, “Baidu has opened up a lot of data processing capabilities in such aspects as voice, picture, video, and natural language processing, which are all beneficial.”

And in cooperation with the Ministry of Civil Affairs(民政部) and nongovernmental organizations, Baidu’s system matches the photographs provided by seekers with those in the population database to achieve highly efficient search results.

After going through 200 million face-training sample photos, Baidu’s AI-based face-recognition technology has achieved a recognition accuracy rate of as high as 99.7 percent. It also supports across-age image comparisons, thus helping parents find their lost children after several years on the basis of their childhood photos.

Many parents whose children were lost at a young age have only their childhood photographs, making the search difficult as features change once a child grows up. But many such lost people have been reunited with their families as AI’s face-recognition technology can match an adult with his/her childhood photograph.

Baidu said it will further improve its program by deepening cooperation with the Ministry of Civil Affairs to cover all the 2,068 grassroots rescue centers, and expand the program to help more people.

This innovative new technology realizes the true goal of technological progress: to make people’s lives better. Applying AI technology for public welfare not only helps people in need, but also improves efficiency and saves costs. It is also a good way for enterprises to demonstrate their corporate social responsibility and contribute to society. It is hoped that more high-tech companies will innovatively apply their technologies to help the public.

1.The first paragraph is mainly to tell us ________.

A.the influence of ABC

B.the importance of AI technology

C.the trend of technology innovation

D.the wide use of Al face-recognition

2.What can we learn about AI face-recognition from text?

A.Its efficiency of search results is not satisfactory.

B.Its accuracy rate greatly needs improving.

C.It has trouble finding lost families only using childhood photos.

D.It’ll help find more children with the support from government.

3.From the passage, we know technological progress is intended to ________.

A.help people accomplish complicated tasks

B.prove the companies’ devotion to society

C.get people to lead a better life

D.offer assistance to the disabled

4.In a newspaper, this text may appear in the section of ________.

A.Science B.Health

C.People D.Lifestyle

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. the rapid development of new computer companies

D. the interaction between old companies and newcomers

2.With wide applications of cloud computing customers can ________.

A. pay less for the older IT systems

B. gain more computing capacity quickly

C. know better about defeating the hackers

D. install software within weeks

3.The problem of “lock-in” can be dangerous because ________.

A. it should ensure data can easily be moved to another provider

B. it can create a network of services connected with devices

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

D. Google enables users to provide services and move data

5.Which of the following sayings can best express the main idea of the passage?

A. Everything has its time and that time must be watched.

B. The grass looks greener on the other side of the fence.

C. A candle lights others and consumes itself.

D. Every white has its black, and every sweet has its sour.

Anchors on China Central Television (CCTV) will need to do some fast talking to replace the popular English acronyms(首字母缩略词) they’re now banned from using. Shanghai Daily reports that “anchors at  (CCTV) have been banned from saying the English acronyms NBA, CBA, GDP, and the like in their programs.”

The replacement for those handy acronyms? Chinese presenters must use the full Chinese name, standardized by the State Administration of Radio, Film and Television.

Although CCTV presenters must already have a score of at least 94 in their government-rated oral Mandarin proficiency exam, saying the full name of organizations like the CBA or WTO ― 10 and 6 character’s long separately ― is sure to challenge even the most skillful anchors. CCTV sports anchor Sun Zhengping tells Shanghai Daily, “A full Chinese explanation of the English initials must be followed if my tongue slips. It is a little trouble but a necessary one because not every audience member can understand the initials.”

Although the government isn’t giving any official explanation for the shift, it is believed to have to do with a proposal by Huang Youyi, director of the China International Publishing Group, at March’s NPC meeting. In his speech, Huang said, “With more and more publications mixing Chinese with English, measures and regulations should be adopted to avoid English invading Chinese. If we don’t pay attention and don’t take measures to stop the expansion of mixing Chinese with English, Chinese won’t be a pure language in a couple of years.”

Although China is far from the first country to take measures to protect local languages (the French and Québécois beat them to it by a long way), acronyms are more about saving time than they are about corrupting a language, we would think. Good luck to the CCTV anchors.

1. CCTV anchors have to “do some fast talking” because they can no longer ______.

A. speak as slowly as they like                            B. mix English into Chinese

C. use shortened Chinese expressions             D. have so much time for their program

2. When Sun Zhengping said “if my tongue slips”, he meant “if I _____”.

A. habitually use an English acronym                B. speak a little bit too fast

C. make a mistake in pronunciation                  D. say something impolite or improper

3. What’s Huang Youyi’s proposal?

A. Using full English names instead of short forms.

B. Translating Chinese terms into proper English.

C. Avoiding Chinese words mixing into English.

D. Keeping our mother tongue as a pure language.

4. What’s the main idea of the last paragraph？

A. China has fallen behind in the matter.         B. The ban is not necessary.

C. Chinese shouldn’t be corrupted.                D. CCTV anchors will have a hard time.

In our fast world of phones, fax machines and computers, the old-fashioned art of letter writing is at risk of disappearing altogether. 1. There is the excitement of its arrival, the pleasure of seeing who it is from and, finally, the enjoyment of the contents.

Letter writing has been part of my life for as long as I can remember. It probably began with the little notes I would write to my mother. My mother, also, always insisted I write my own thank-you letters for Christmas and birthday presents. 2..

When I left home at 18 to train as a doctor in London, I would write once a week, and so would my mother. Occasionally my father would write and it was always a joy to receive his long, amusing letters. 3. Of course, we also made phone calls but it is the letters that I remember most.

There were also letters from my boyfriend. In our youth he had to work or study away at some time and we were only able to stay in touch by letter. 4. I found that I could often express myself more easily in writing than by talking.

I love the letters that come with birthday or Christmas cards. Notes are appreciated, but how much better to have a year’s supply of news! And it’s better still when it’s an airmail envelope with beautiful stamps.

5. Like my mother before me, I insist they write their own thank-you letters. My daughter writes to me little letters, just as I did to my mother. I strongly urge readers not to allow letter writing to become another “lost art”.

A.Poor handwriting can spoil (破坏) your enjoyment of a letter.

B.I am pleased that my children are carrying on the tradition.

C.We had been writing to each other for a long time but never met.

D.It didn’t matter how short or untidy they were as long as they were letters.

E.But instead of harming the relationship, letter writing seemed to improve them.

F.Yet, to me, receiving a letter cannot be matched by any form of communication.

G.The letters from him contained just everyday events concerning my parents and their friends.

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:
