The average computer user has between 5 and 15 username/password combinations to log in different kinds of accounts. Some demand you use a specific number of symbols and digits, while others require you to change your password every 60 days. The feeling of confusion resulting from memorizing these login information has grown so common that it actually has a name: password fatigue(疲劳).

    Having to remember so many different passwords is annoying, but it can also be dangerous. Because it is virtually impossible to remember a unique password for each of these accounts, many people leave handwritten lists of usernames and passwords on or next to their computers.

    {#blank#}1{#/blank#} While these practices make it easier to remember login information, they also make it easier for thieves to hack into accounts.

    Single Sign-On (SSO) confirmation and password management software can help solve this problem. With SSO, users only need to remember one password to log in to the main system.

    {#blank#}2{#/blank#} SSO software is typically used by large companies, schools, or libraries.

    {#blank#}3{#/blank#} If a user loses or forgets the password required to log in to SSO software, the user will then lose access to all of the applications linked to the SSO account. Users who rely on password management software face the same problems.

    Although most websites or network systems allow users to recover or change lost passwords by providing email addresses or answering a prompt（提示）, this process can waste time and cause further frustration. What is more, recovering a forgotten password is only a temporary solution.

    Some computer scientists have suggested computers rely on biometrics(生物测定学). {#blank#}5{#/blank#} The use of biometrics raises questions concerning privacy and can also be expensive to practice.

    Software engineers and computer security experts are still searching for the cure to password fatigue. Until they find the perfect solution, however, everyone will simply have to rely on the password system currently in place.

    Far out in the lake was a large wooden platform(平台) on which stood an improbably high diving board- a kind of wooden Eiffel Tower. It was, I'm sure, the county's tallest wooden structure (结构) and no one had ever been known to jump from it. So it was quite a shock when our teacher, Mr. Milton, announced that he would dive off the high board that very afternoon.

    Word of his questionable plan was already spreading through town as Mr. Milton swam out to the platform. He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board , then look some deep breaths and finally stood at the edge. He was going to do it.

    Several hundred people had gathered at the shore to watch. Mr. Milton stood for quite along time ;then he raised his arms, took one bounce(弹跳) and launched himself into ;perfect dive. He fell with perfect style for what seemed minutes. The crowd fell silent. But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic(惊慌)，waving his arms and legs like someone having a bad dream. When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide, obviously hoping that it would somehow slow his fall. It didn't. He hit the water at over six hundred miles an hour, making birds fly out of their trees three miles away. I don't think he entered the water at all. He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface , like an autumn leaf.

    He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon. Occasionally he accepted a little water, but otherwise was too shocked to speak.

    It was the best day of my life.

    Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.

    Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, and the life of American people. Most of the radio programs are music.

    Pop or popular music singers make much money. They make a CD or tape which radio stations use in many places. Once the popular singer is heard all over the country, young people buy his or her tapes. Some of the money from these tapes goes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.

    There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This is started by cowboys who would sing at night to the cows they were watching.

    Most people agree that being a good driver means being safe and not aggressive on the road. One debate some people still argue, however, is who drives better: men or women? Although it's impossible to say that one gender drives better than another definitively, there are some noteworthy trends.

    Male drivers tend to have more accidents

    Data from the Insurance Institute for Highway Safety (IIHS) shows that male drivers tend to have more total accidents than females. The IIHS, an independent non­profit devoted to reducing car accidents, also found that 71 percent of all motor vehicle crash deaths in 2017 were males. Although the gap has narrowed, almost every year from 1975 to 2017, the number of male crash deaths was more than twice the number of female crash deaths, per the IIHS.

    Women might be less­confident behind the wheel

    Although male drivers have more accidents, other research shows women aren't "perfect" drivers, either. Researchers from the University of Michigan's Transportation Research Institute studied traffic accidents over 20 years and found that female drivers are more likely to run into a car driven by another woman than a man. The study, however, doesn't explain possible reasons for this pattern.

    One that they might consider testing in the future is that some research also shows women are less­confident behind the wheel than men. A study from UCLA exploring the relationship between new drivers' skills and different variables, including gender(性别), shows female students were less confident drivers than men.

    So are men better drivers than women?

    Gender is just one factor when it comes to safe driving, along with others such as age, and even the time of day people drive. One study shows that both genders have a greater accident risk when driving at night, but males still have a higher risk at all times of the day. Driving quality also changes based on location, too, as some states are more dangerous than others. Data from the National Highway Traffic Safety Administration shows that Wyoming, Mississippi, and Montana have high accident death rates, without regards to gender. It goes to show that everyone should learn and practice safe driving habits instead of worrying about who drives better.

    The American Craftsman style is a type of design. It was popular from 1900 to the 1930s. It changed the style of building in the United States.

    The craftsman style originally began in Europe. The British Arts and Crafts style arose in the 1860s. The unique designs of this movement tried to offer dignity to the common person. Handmade items were preferred because they were thought better than items that were mass-produced. But this British style was still Victorian. It still only served the wealthiest clients.

    In 1897 a group of Boston architects brought these handcrafted styles to American. They planned a show of craft objects, which turned out to be a huge success. Here they realized the potential and established the Society of Arts and Crafts on June 28, 1897. Its slogan was "to develop and encourage higher standards in the handicrafts."

    The American style began as the Victorian Era was ending. It emphasized handmade work. Originality and simplicity were highly valued. Local materials and the quality of the handicraft were very important, these traits were meant to dignify the modest homes of the middle class.

    These simple designs used glass and wood that were produced locally. They were also very elegant. The metalwork was a reaction to Victorian Opulence. The increase of mass-produced housing items was rejected. The American Craftsman used clean lines. It also relied on sturdy structure. Natural materials were always used in these houses if possible.

    This style introduced many changes to the average American home. New designs were made for families without servants. This was a trait of the new middle class. The kitchen went from being a hidden room to a prominent one. Another development was the breakfast nook. This new area provided the family with a place to gather at any time of day.

    Also, inspirational to the Craftsman style were the Shaker and Mission designs. The American Craftsman style led to the Art Deco Movement of the 1930s.

    Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(预定), which can add up to discounts on restaurant visits.

    Max McCalman's Cheese&Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese&Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese&Wine Pairing app is free.

    HappyCow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

    "Where Chefs Eat" is a 975-pagc book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.
