    Many of you may know that Jakarta is the capital city of Indonesia. 1. In September, Indonesia announced that the country will move its capital from Jakarta, on the island of Java, to Kalimantan, on the island of Borneo. This is big news for Indonesia. Indeed, it would be for any country.

The word ''capital'' comes from the Latin word ''caput'', meaning ''head''. Government institutions (机构), such as legislative (立法) and judicial (司法) bodies, are located in capital cities. 2.

In English-language news reports, when you read ''relations between Beijing and Moscow'', it actually means ''relations between the Chinese and Russian governments''. 3. In many countries, the capital is the richest city. This is because when a city becomes a major business center, it takes a more important place on the world stage. London, for example, has been the economic center of Britain for nearly 2,000 years, so it's naturally been the capital for much of that time.

4. Brazil's capital used to be Rio de Janeiro, a coastal city. Later the capital moved to the inland city of Brasilia. Part of the reason is that coastal cities can be attacked (攻击) more easily. In the case of Indonesia, the new capital was chosen in order to achieve balanced development in different areas. Kalimantan is an underdeveloped area. 5.

A.This will soon change.

B.Sometimes, capitals are chosen for safety reasons.

C.Some new capitals are planned and built in undeveloped areas.

D.Countries sometimes move their capitals from one city to another.

E.Therefore, it is important to choose a good spot for one's capital.

F.By becoming the new capital, it can expect faster economic growth.

G.The leaders of a country usually work and live in the capital as well.

    Tired of his staff always keeping checking emails and the sound of their smart phones, Paul Devoy decided to ban all phones, tablets and laptops from meetings. He says meetings have become much more productive.

It is true that the sound of the phones has a harmful effect on our ability to concentrate. One Standford University study shows that people who regularly deal with electronic alerts and messages do not pay attention or control their memory as well as those who concentrate on doing one thing at a time.

Mr Devoy introduced his ban on technology in meetings, but he says exceptions are made if important personal calls are expected.

''These things need to be reasonable, '' he says, adding he was surprised to find that his staff all accepted the ban and some were even enthusiastic about the ban.

Mr Devoy has gone a step further in his purge(清除)of technology. He has banned PowerPoint presentations from meetings, and finds that discussion now flows more freely.

Nena Chaletzos, leader and founder of online travel start-up Luxtripper, is also a supporter of tech-free meetings. She runs her company’s weekly meeting without phones or laptops. Instead, for the one-hour meeting, her team of eight are asked to bring along the A3 whiteboard they have each been given, on which they write meeting notes and action points. At the end of the meeting, everyone's actions for the week are agreed. The whiteboards are kept on show and tasks are erased as they are completed.

''I tell them to bring their ideas and brains to the meeting, not their technology, '' Ms Chaletzos says. Once the meeting went on for three hours, discussion is now so much more focused and productive that it can be kept to a strict 60 minutes, she says. At first, the staff worried about customers being unable to reach them, but Ms Chaletzos told them that all they needed was a warning. An unexpected result, she says, is that meetings are much more friendly and open.

Technology is still very much used at the start-up but only at the right time. For example, Ms Chaletzos' team use Slack, which has helped end the need for other meetings.

1.Why did Paul Devoy ban phones from meetings?

A.Because his staff wasted too much time on emails.

B.Because phones weakened his staff's ability to focus.

C.Because he doesn't like the sound of smart phones.

D.Because his staff are buried in their personal affairs.

2.A study from Stanford University is mentioned to ______.

A.introduce Nena Chaletzo's decision

B.prove the harm the sound of smart phones causes

C.show Paul Devoy's decision is right

D.give a similar story to the one mentioned above

3.If a person in Paul Devoy's company is allowed to answer personal calls during the meeting, ___.

A.the person must be Paul Devoy himself B.other staff will ask for the same right

C.something important must happen D.Paul Devoy will punish the person

4.After technology was banned from meetings, Paul Devoy's staff ______.

A.disagreed and stopped working B.were happy to observe the ban

C.thought that he would fail D.disappointed him a lot

    A new web standard is expected to kill passwords, meaning users will no longer have to remember difficult logins for each and every website or service they use.

The Web Authentication (WebAuthn) standard is designed to replace the password with biometrics and devices that users already own, such as a security key, a smartphone, a fingerprint scanner or webcam. Instead of having to remember an increasingly long string of characters, users can authenticate their login with their body or something they have in their possession, communicating directly with the website via Bluetooth, USB or NFC.

''WebAuthn will change the way that people access the Web, '' said Jeff Jaffe, chief executive of the World Wide Web Consortium (W3C), the body that controls web standards. One example of how WebAuthn will work is that when a user visits a site they want to log into, they input a user name and then get an alert on their smartphone. Tapping on the alert on their phone then logs them into the website without the need for a password.

WebAuthn promises to protect users against phishing attacks and the use of stolen credentials as there will be nothing to steal, the authentication token is generated and used once by their specific device each time the user logs in.

''After years of increasingly severe data breaches and password credential theft, now is the time for service providers to end their dependency on vulnerable passwords and one-time-passcodes and adopt phishing-resistant FIDO Authentication for all websites and applications, '' said Brett McDowell, executive director of the FIDO Alliance, one of the bodies pushing the new standard.

WebAuthn should also help people use unique login details for each and every service they use, instead of using the same login and password for every site, which many people still do, leaving them vulnerable to further attacks if one site is hacked.

The W3C has moved WebAuthn to what's called the ''candidate recommendation'' stage – the penultimate step before it becomes an approved web standard – inviting sites and services to begin implementing it. The web standards body announced that Google, Microsoft and Mozilla had committed to supporting WebAuthn, meaning that all major web browsers short of Apple's Safari will implement the new standard.

''While there are many web security problems and we can't fix them all, relying on passwords is one of the weakest links. With WebAuthn's multi-factor solutions we are eliminating this weak link, '' said Jaffe.

Several sites and services already use similar methods to log in, including Google and Facebook, which can both be logged into using a USB security key. But a single cross-platform, cross-service standard ratified by the W3C will mean that many more sites and services will be able to kill the password as the defacto login method.

WebAuthn is the culmination of many years of work and the change will not happen overnight. But as it increasingly seems inevitable that our email or other online services will get hacked into, removing the password is an important step in improving online security and making using sites and services easier.

1.What's the purpose of the new Web Authentication standard?

A.To create a way to login in place of the traditional password.

B.To help users to improve the way of inventing the password.

C.To make people visit a site much faster and more smoothly.

D.To inform readers of a new tool against phishing attacks.

2.What does the underlined part ''which many people still do'' mean in Paragraph 6?

A.They change their passwords when using a computer system.

B.They use the same login and password on different websites.

C.They copy information from the web in the same way as before.

D.They worry about being attacked while surfing the Internet.

3.According to Jaffe, web security problems ______.

A.have been solved completely at present

B.are often connected with hacking and phishing

C.will disappear one day with the WebAthn

D.may probably be casted by unsafe passwords

4.What can we infer from the last paragraph?

A.WebAuthn is the important product through longtime efforts.

B.WebAuthn will change people's way of using computer sooner or later.

C.Emails are safer ways for people to send and receive information.

D.Removing passwords will surely end the risks caused by hacking.
