1 . Imagine you're standing in line to buy an after-school snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code with your smartphone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.
In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since lasts year, San-sun has featured eye-scanning technology in its top smartphone, while Apple's new iPhone X can even scan a user's face.
When introducing the new iPhone's Face ID feature at Apple's Keynote Event in September. Phil Schiller, Apple's senior vice president, said. “
But it's already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face. Quartz reported. And they aren't even twins.
“We may expect too much from bio-metrics.” Anil Jain, a computer science professor at Michigan State University. told CBS news. “No security systems are perfect.”
Earlier this year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smartphone for police.
“It's good to see bio-metrics being used more,” Jain told CBS News, “because it adds another factor for security.
| A．But despite its popularity, experts warn that bio-metrics might not be as secure as we'd imagined |
| B．Security experts don't think it absolutely necessary to use biometric technology. |
| C．But using different security measures is the best defense. |
| D．Now, this type of technology might not be far away. |
| E．If a person's biometric information is stolen, that could have extremely serious results for him. |
| F．The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million. |
2 . What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a firiend wants to borrow some money from you. You say “I wish I could help you but I'm short of money myself.” In fact, you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie?
Professor Jerald Jellison of the University of Southern Califormia has made a scientific study of lying. According to him, women are better liars than men. particular when telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way.
Research has also been done into the way people's behavior changes in a number of small apparently unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now.” They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The up of the nose is very sensitive to such changes and the increased pressure make sit itch.
Another gesture which give liars away is that the writer Desmond Morris in his book Man-watching calls “the mouth cover” He says there are several typical forms of this, such as covering part of the mouth with the fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such as gesture can be understood as an unconscious attempt on the part of the lair to stop himself or herself from lying.
Of course, such gestures as rubbing the nose or covering the mouth, or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently n this situation. It is not one gesture alone that gives the lair away but whole number of things and in particular the context in which the lie is told.

3 . Zelda Fitzgerald, as is revealed by numerous personal books and letters, wore many labels in her life. She was “the original flapper girl” and “the spirit of the Jazz Age.” Married to the celebrated writer F. Scott Fitzgerald (author of The Gireat Giatsby), she was by turns his muse and the woman who ruined his life. In her later years she was “Crazy Zelda”.
Accurate as all these descriptions may be, they do not tell the whole story. Born in Montgomery, Alabama, she was noted for her beauty and high spirits in dancing. In July 1918, at a country club dance, Fitzgerald was hooked immediately by the beautiful and charming 18-year-old Zelda who out-shined(使逊色)other beauties with her distinguished ballet. A light affection evolved into a lengthy long-distance pursuit of weekly letters, with Fitzgerald aware of her uncommitted dating of other men. He courted her after his discharge from the Army in February 1919, but Zelda had doubts. Her fiance wasn't rich and there was no guarantee he’d ever be famous. His short stories didn’t sell. His apartment was a dump. Zelda gave back the ring. Hoping to fix the “no money” part of his problem. Fitzgerald quit the job and started to rewrite novels for success and money so that he could win back his girl. Finally, he made it! On March 20, 1920, his novel This Side of Paradise got published and Zelda agreed to marry him.
However, their marriage was troubled by wild drinking, fighting, infidelity(不忠实)and bitter recriminations. Emest Hemingway, whom Zelda disliked, blamed her for Scot’s declining literary output, though she has also been portrayed as the victim of an overbearing husbano Actually. Zelda was also creative, pursuing both dancing and writing. Some scholars have portrayed Zelda as a creative talent ignored by the patriarchal(男权的)society of the day. Her inspiration was even drawn by her husband in literary creation-Scott used their relationship as material in his novels, even borrowing episodes from Zelda’s diary and applying them into his fictional writings. She detested(讨厌)her husband’s practice: “Mr. Fitzgerald-I believe that is how he spells his name-seems to believe that plagiarism begins at home.” To seek an artistic identity of her own value, as she put it “I wish I could write a beautiful book to break those hearts that are soon to cease to exist.”
Nevertheless her unique personality was starting to seem more unbalanced than charming. The couple-like the rest of the nation-was living on borrowed time. In October 1929 the stock market crashed, triggering the Great Depression. Six months later, Zelda suffered her first nervous breakdown. After being diagnosed with schizophrenia（精神分裂), she was increasingly confined to specialist clinics, and since then has departed with her husband. Zelda died later in a fire at her hospital in Asheville, North Carolina, putting an end to her flamboyant(绚丽夺目的)life. A young woman, especially one in the 1920s, who was against traditional dress and behavior.
