How to Make Your Email Really Secure

Email is the most used communications medium for business and for many of us at home too, but few people outside IT know how to truly secure their email. Here's a quick look at some of the ways you can carry on encrypted(加密的) conversations.1.

Your Gmail messages being sent are encrypted. However, unless the receiver is reading email using a Google browser(浏览器) or Gmail app, they don't stay encrypted. And, of course, Google itself freely admits that its software reads all of your email for advertising purposes. Some programs, like the paid version of Outlook, offer an encryption feature. 2. It requires that you and your receiver exchange something called a digital signature.

3. The disadvantage—and you knew there would be one—is that your receiver must also subscribe to that service, or enter a password to open each message you send. They're fine if your only secure conversations are with one or two people. 4.

Another option for those wishing to send secure text correspondence: Don't use email at all. 5. These apps encrypt your messages on both ends and throughout their sending. Here again, though, they limit your communication to people who also have and use those same apps.

A.Protect the machine you use email on.

B.Free accounts limit the size of your messages and attachments.

C.But setting it up takes much trouble, and surely not for the masses.

D.Instead, use a chat program like CryptoCat, ChatSecure, or PQChat.

E.But you're never going to persuade the whole world to sign up to get your emails.

F.Email providers like Tutanota, and Protonmail automatically encrypt all the mail you send.

G.The concern that your words could be stolen and used against you someday will be solved.

    A UK supermarket has become the first in the world to let shoppers pay using just the veins (纹理)in their fingertips. Customers at the Costcutter Store, at Brunel University in London, can now pay using their unique vein pattern to identify themselves.

The firm behind the technology, Sthaler, has said it is in "serious talks" with other major UK supermarkets to adopt hi-tech finger vein scanners at pay points across thousands of stores. It works by using infrared(红外线)to scan people's finger veins and then links this unique biometric map to their bank cards. Customers' bank details are then stored with payment provider Worldpay and in the same way you can store your card details when shopping online. Shoppers can then turn up to the supermarket with nothing on them but their own hands and use them to make payments in just three seconds.

Previous studies have found fingerprint recognition, used widely on mobile phones, is likely to be hacked and can be copied even from fingerprint left on phone screens. But Sthaler claims vein technology is the most secure biometric identification method as it cannot be copied or stolen. The technology uses an infrared light to create a detailed map of the vein pattern in your finger. It requires the person to be alive, meaning in the unlikely event a criminal hacks(非法侵入)off someone's finger, it would not work.

Sthaler said it takes just one minute to sign up to the system firstly and, after that, it takes just seconds to place your finger in a scanner each time you reach the supermarket checkout. Simon Binns, commercial director of Sthaler, told the Daily Telegraph, ''This makes payments so much easier for customers. There are no known occurrences where this security has been broken. ''

1.Which supermarket in the world can now use the vein-recognition technology?

A.Grocery stores in London.

B.Thousands of stores in the UK.

C.University supermarkets in the UK.

D.Costcutter Store at Brunel University in London.

2.What message does Sthaler intend to convey according to Paragraph 3?

A.The system is safe. B.Hacker attacks are unlikely.

C.Vein patterns can be copied. D.The technology is convenient.

3.What should customers do before using the system?

A.Copy the fingerprint. B.Protect against hacking.

C.Contact the supermarket. D.Register on the system.

4.What do we know about the vein-recognition system?

A.It has been hacked.

B.It will be adopted by more shops.

C.Its company is optimistic about it.

D.Its technology needs further improvement.

    If someone is crying in an attempt to fake sorrow, we say they are shedding “crocodile tears”. But how and why did we start relating insincere displays of feelings to crocodiles?

The origin may have become popular around the 14th century when a bestseller, The Voyage and Travel of Sir John Mandeville, referenced a kind of snake who drops tears while eating their human victims.

In the centuries since, crying crocodiles have been related to fake sorrow. The expression has been used as a story to teach sincere regret, by Shakespeare and, more recently, by media mocking tearful politicians or murder suspects.

In 2007, University of Florida zoologist Kent Vliet actually proved that the animals do drop tears while snacking. But because crocodiles eat while in the water—making a study of their meal-time tears difficult—he studied their close relatives, alligators, who might dine on dry land. Out of the seven he filmed eating at a Florida alligator park, five teared up before, during, and after eating.

Vliet’s theory is that when the animals enthusiastically hit their jaws, the movement forces air through the crocodiles’ sinuses and finally empties tears into their eyes. Their eyes not only water but can bubble, as Vliet witnessed at the alligator park, where some even teared up in expectation of their meal of chicks and other food.

Vliet was asked to investigate the biology behind this phenomenon by Malcolm Shaner, a doctor, about why facial palsy sufferers cry when they chew. Findings suggest that this is similar to the case of crocodiles.

1.What does “crocodile tears” express?

A.False sadness. B.Sincere apology.

C.Untrue suffering. D.Faithful concern.

2.Who has studied humans’ shedding tears while chewing?

A.John Mandeville. B.Shakespeare.

C.Kent Vliet. D.Malcolm Shaner.

3.What's the meaning of the underlined word “mocking” in Paragraph 3?

A.Teasing. B.Reporting. C.Fooling. D.Comforting.

4.What's the author's purpose in writing the passage?

A.To describe the physical appearance of crocodiles.

B.To give a biological explanation of crocodile tears.

C.To clarify a misunderstanding of political leaders.

D.To introduce results of research on human feelings.

    Carl Jones' love for animals began in his childhood. As a boy, he rescued injured wild creatures. In the 1970s, when the 24-year-old biologist learned that the Mauritius kestrel(红隼) is dying out, he decided to do his part.

He arrived on the island in an age of extinction. Even his employers of BirdLife International instructed him to “pull out elegantly” and leave the kestrel-saving to Mauritius government officials. That actually meant closing it down, because the Mauritians didn’t have the resources or ability.

Despite various difficulties, Jones holds the belief that all species are savable and humans need to live closely with other species. He has done so all his life and developed his hands-on approach to saving species.

Jones challenges the classic conservation wisdom that we must first understand the reasons for a species, decline and restore its habitat. Instead, he argues that scientists must identify the limiting factors on a species' population—food, nesting sites, competition, killing, disease—with practical fieldwork. “If there's a shortage of food, you will start feeding. If there's a shortage of nesting sites, you will put up nesting boxes. You don't need endless PhD students studying a species for 20 years. ” Conservation science, he argues, is often too remote. “Do you sit back and monitor a sick patient or do you treat them and see what works? A lot of species have been studied to extinction. ”

In Mauritius, Jones has preserved many plant species and nine animals. Without Carl Jones, the world might have lost the Mauritius kestrel, the pink pigeon and more.

1.What did BirdLife International want Carl Jones to do?

A.Live closely with other species. B.Do his part in an age of distinction.

C.Co-operate with the local government. D.Give up his decision to save the Mauritius kestrel.

2.What's Carl Jones’ approach to saving species?

A.Working on specific factors. B.Getting necessary resources.

C.Analyzing reasons for a species' decline. D.Following the classic conservation wisdom.

3.When it comes to saving endangered species, what's Carl Jones' opinion on studying them?

A.It's a waste of time. B.It's an impractical approach.

C.It should be done in remote areas. D.It takes highly educated personnel.

4.What can we infer about Carl Jones' work?

A.It is based on abundant research. B.It has produced beneficial results.

C.It received the government’ support. D.It is against the basic laws of fieldwork.
