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.

    How to Adjust to a New School

    School is a base for students, where they learn to succeed{#blank#}1{#/blank#}When you go to a new school, you might worry that you don't know anyone. You worry that you might get lost, or if the teachers are strict. Here are some ways to help you adjust to a new school.

    Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.

    {#blank#}1{#/blank#} We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time.

    "I adore dancing," says Lester Bridges, the owner of a dance studio in Iowa. "I can't imagine doing anything else with my life." Bridges runs dance classes for all ages. "Teaching dance is wonderful. {#blank#}2{#/blank#} It's great to watch them. For many of them, it's a way of meeting people and having a social life."

    {#blank#}3{#/blank#} "I can tell you about one young couple," says Bridges. "They're learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile. {#blank#}4{#/blank#}"

    So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, "Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better. {#blank#}5{#/blank#} I find it hard to stop! Dancing reminds me I'm alive."

A. So why do we dance?

B. Dance in the U.S. is everywhere.

C .My older students say it makes them feel young.

D. If you like dancing outdoors, come to America.

E. Dancing seems to change their feeling completely.

F. I keep practicing even when I'm extremely tired.

G. They stayed up all night long singing and dancing.

    A lack of sleep causes many medical conditions that greatly affect the quality of life. While no one knows why we sleep, it is a universal biological need.{#blank#}1{#/blank#}

    How much sleep do I actually need?

    A study in Finland found that the amount of sleep that relates to the fewest sick days was 7.63 hours a night for women and 7.76 hours for men.{#blank#}2{#/blank#}When we get sleep fewer than seven hours or our sleep often falls below six hours, we are at an increased risk of health problems.

    {#blank#}3{#/blank#}

    Today, some people practice “polyphasic (一昼夜活动和休息多次的)sleep”,based on the idea that by dividing your sleep into parts, you can get away with less of it .Professor Dinges concludes it's possible to train oneself to need less sleep in short periods.{#blank#}4{#/blank#}And he notes that even for those who can function well on less sleep, we still don't know how the practice might be affecting chemical processes, mood, and other factors.

    I can't sleep. Is my phone really keeping me up?

    When light enters your eye, it hits your retina to send signals to the hypothalamus (下丘脑),which controls sleep cycles. When your retina takes in less light, your hypothalamus assumes it's time to sleep and it'll signal the pineal gland (松果腺)to make you sleepy. And when the hypothalamus senses light, it tells the pineal gland to stop its work.{#blank#}5{#/blank#} Some research suggests that the light from phones and tablets are especially influential in human sleep cycles.

A. Adequate sleep can benefit us a lot.

B. Can I train myself to need less sleep?

C. How can I make myself sleep less?

D. No animal with a brain can survive without it.

E. This is why we're told to minimize screen time before bed.

F. And most adults function best after seven to nine hours of sleep a night.

G. But he adds it doesn't seem possible to train oneself to need less sleep per 24-hour cycle.

Four simple steps to be truly thankful

    Thanksgiving is more than pie and turkey. It's about helping and loving the family, friends and world around you. The following tips will help you show your thankfulness.

    ⒈Family

    A lot can happen in a year. Your family may have added some loved ones and lost some at the same time. {#blank#}1{#/blank#}, and let your family know how important they are to you and how glad you are that you all could get together.

    ⒉Friends

    Do what you always do — throw a party. In college, Chicago natives Heather and Nosheen threw a dinner party for their friends on Thanksgiving and came up with HANTDE: Heather and Nosheen's Thanksgiving Day Extravaganza. {#blank#}2{#/blank#}.

    "HANDTE is a reunion time that we all look forward to every year," Heather says. "{#blank#}3{#/blank#}, so HANTDE has become a time to see and be with each other."

    ⒊Community (社区)

    You could volunteer at a local soup kitchen or bring unused items to a food bank. {#blank#}4{#/blank#}. This year, Heather and Nosheen are asking their HANTDE guests to offer a donation, which they will donate to help low-income families.

    ⒋Self

    {#blank#}5{#/blank#}, for example, the debts you paid off or the friends you've made. Being able to give thanks for yourself and what you've done is the first step to being able to show thankfulness to others.

    Getting your children to study can be a little like getting them to eat their vegetables.

    {#blank#}1{#/blank#} Make a study time and have it at the same time every day. This will help your kids to learn to schedule their day and will give them a sense of control over how they spend their time. Allow them to study in blocks of time, such as for half an hour with a five­ minute break in the middle. {#blank#}2{#/blank#} Ideal(理想的) study times are after dinner or right after school before dinner.

    Never allow your children to study in front of the television, as that will encourage passive activity. {#blank#}3{#/blank#}You'll also need to help your kids find the right place to study. After you've set up a good study time for little learners, set up a good place where they can get those creative juices flowing.

    {#blank#}4{#/blank#} Make sure there is a table or a desk and a comfortable chair.

    {#blank#}5{#/blank#} This includes helping them out with their homework sometimes and being there for them with the answers to any questions. The input you give your children during study periods will help form a bond and help make studying enjoyable.

A. Pick a place where your children can study properly.

B. Hold them to the schedule they create for themselves.

C. Finally, spend time with your kids when they're studying.

D. Keep the atmosphere light and offer lots of encouragement, too.

E. Instead, use TV as a treat or a reward when the homework is completed.
