Iris scanning and other technologies , such as fingerprint and voice scanning , have appeared in many science fiction movies in the past. Today , these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics( 生物测定学) a fast developing area of automatic personal identification technology . Basically , biometrics uses various ways to verify a persons identity , based on the individual’s unique characteristics ,including fingerprints , voices, irises, body heat patterns, facial images, handprints , signatures and so on.

Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember , forget, lose or steal.

The voice scan is the simplest and most affordable form of biometrics . It only requires a computer, a microphone and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purposes.

For additional safety, fingerprint and handprint scans can also be employed . Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.

Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology , full facial scans , is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd.

The potential of biometrics is exciting and encouraging . With continued development , testing , and application , current technologies will become even more effective in the future. Soon , the days of password and car keys will be gone . Just don’t leave home without your fingerprints!

At other locations of the store, shoppers enter by scanning the Amazon Go app. That's still the case for customers paying with a credit card, but people paying with cash will have an “entry associate” scan them through the turnstiles (旋转栅门). Once they’re finished, those shoppers will check out with an Amazon Go employee and receive a paper receipt. Cashless customers can still walk out by scanning a phone that has the Amazon Go app at the turnstiles. Customers using the Go app can exit without waiting and get a digitized receipt.

The 1,300-square-foot New York store-the first Amazon Go store on the East Coast-will offer prepared foods, such as sandwiches and salads, It will also have Amazon Meal Kits and locally made options.

Amazon says it will begin accepting cash at its other Go stores “over time.” A number of retailers (零售商) and restaurants, such as Sweetgreen and Dos Toros Taqueria, are facing roadblocks to their cashless recommendations.

New Jersey Governor Phil Murphy recently signed a law banning cashless stores in that state. Philadelphia also passed a law to prohibit cashless stores earlier this month, and officials in New York City, Washington and San Francisco are considering similar moves. The federal government does not require retailers to accept cash.

“While card-only may be convenient for some businesses, it can actually be discriminatory against poor communities that don’t have as much access to banks or lines of credit,” said New Jersey State Senator Nellie Pou, who sponsored the state’s new law. Not accepting cash could also be bad for business. Americans use it in 30% of all business deals, according to a 2017 report from the Federal Reserve Bank of San Francisco.

Today is Sunday. The sky is full of sunshine, so does my life. At about 9:00 a.m., I go to the bookstore with my friends. There was a lot of new books. I didn’t know what one to buy because these books were all useful to me. At 10:00, we went to cinema. The film was called Titanic but some people were waiting outside the booking office. It took to us about 3 hours to see it. Having seen the film, everyone was deeply moving. Some of my friends even burst out tears. From the story, I understand that love is noble and valuable. That’s a really wonderful film. It is very worth seeing again.

What a happy day! I hope tomorrow I will be happier!

Children can be born nervous and if you have such a baby, you’ll tend to prevent them from getting worried. So if they fear dogs, You’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, an anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke (抚摸） it, and talk about the dog being friendly. Once your child dares to stroke a dog-one that’s good with children, of course-then you should encourage them to carry on until they feel calmer, and reward them for‘being brave’.”

According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.

Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me,who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.

Dr.Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.

Besides, the idea that young women actually have ADHD often causes skepticism. As a top student,I didn't believe my diagnosis at first. My friends were also confused,and rather certain my doctor was misguided.

"Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says."Girls will hide their inability to meet social expectations. They see their trouble organizing,and concentrating as character flaws（缺陷）."

These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.
