What is time? Is it a thing to be saved or spent or wasted, like money? Or is it something we have no control over, like the weather? Is time the same all over the world? That's an easy question, you say. Wherever you go, a minute is 60 seconds, an hour is 60 minutes, a day is 24 hours, and so forth. Well, maybe. But in America, time is more than that. Americans see time as a valuable resource. Maybe that's why they are fond of the expression, "Time is money."

To Americans, punctuality is a way of showing respect for other people's time. Being more than 10 minutes late to an appointment usually calls for an apology, and maybe an explanation. People who are running late often call ahead to let others know of the delay. Of course, the less formal the situation, the less important it is to be exactly on time. At informal get-togethers, for example, people often arrive as much as 30 minutes past the appointed time. But they usually don't try that at work.

American lifestyles show how much people respect the time of others. When people plan an event, they often set the time days or weeks in advance. Once the time is fixed, it takes almost an emergency to change it. If people want to come to your house for a friendly visit, they will usually call first to make sure it is suitable. Only very close friends will just "drop by" unannounced. Also, people hesitate to call others late at night for fear they might be in bed. The time may vary, but most folks think twice about calling after 10:00 p.m.

A．Because they can’t control time.

B．Because they is the same all over the world.

A．it doesn’t matter

B．it is necessary for you to make an apology

C．you needn’t say anything about your delay

D．you needn’t call ahead to let others know you will be late.

3.What does the last paragraph mainly discuss?

A．The reasons why Americans value time.

B．The ways to show their respect to the time of others.

C．Being on time is highly valued in the USA.

D．Never drop in on others unless you are their close friends.

That's an easy question, you say. Wherever you go, a minute is 60 seconds, an hour is 60 minutes, a day is 24 hours, and so forth. But in America, time is more than that. Americans see time as a valuable resource. Maybe that's why they are fond of the expression, "Time is money."

Because Americans believe time is a limited resource, they try to conserve and manage it. People in the U.S. often attend seminars or read books on time management. It seems they all want to organize their time better. Professionals carry around pocket planners -- some in electronic form -- to keep track of appointments and deadlines. People do all they can to squeeze more time out of their time. The early American hero Benjamin Franklin expressed this view best: "Do you love life? Then do not waste time, for that is the stuff life is made of."

At informal get-togethers, for example, people often arrive as much as 30 minutes past the appointed time.

To outsiders, Americans seem tied to the clock. People in other cultures value relationships more than schedules. In these societies, people don't try to control time, but to experience it. Even Americans would admit that no one can master time. Time -- like money -- slips all too easily through our fingers. And time -- like the weather-- is very hard to predict. Nevertheless, time is one of life's most precious gifts. And unwrapping it is half the fun.

1.What’s the main topic of this passage?

2.What’s the meaning of the underlined word “conserve”?

3.The sentence “Americans seem tied to the clock” probably means __________.

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.
