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(疲勞).

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.

1. 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.

2.SSO software is typically used by large companies, schools, or libraries.

3.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.

4.

Some computer scientists have suggested computers rely on biometrics(生物測定學(xué)). 5. 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.

A. It does not address the larger problem of password fatigue.

B. These software programs have been built into many major web browsers

C. The problem with password management software makes users feel powerless.

D. The SSO software then automatically logs the user in to other accounts within the system.

E. However, SSO confirmation and password management software also have drawbacks.

F. This is a method of recognizing human users based on unique traits, such as fingerprints, voice,

or DNA.

G. Others solve this problem by using the same password for every account or using extremely

simple passwords.

Dear Mom, Clear My Calendar

September is around the corner, and some of us are already complaining about summer’s end. But parents have a special reason to do so. The end of summer means the start of school. And these days, planning a young child’s schedule is a big challenge. The challenge is no longer finding activities to fill a child’s day; it is saying no to the hundreds of options available. Our mailbox is filled with brochures urging us to sign our kids up for classes from cooking to martial arts(武術(shù)).

Educators are themselves discouraged by the number of special classes that many children attend. In the name of “enrichment,” three-year-olds not only go to preschool in the morning but study French or gymnastics after lunch. One teacher tells of a four-year-old asking for help in the toilet before hurrying off to tennis. Another teacher says that children sometimes hold on to her at pickup time. What happened to unstructured time?

A generous explanation is that we enjoy giving children opportunities we never had. The truth however is that many parents have doubts about how much time they spend away from their families. And one way to reduce this guilt is to believe that time spent in these classes is somehow more beneficial to children than the time we know we should be giving them ourselves.

David Elkind, an expert on children, suggests that the 1960s gave birth to the belief that earlier is better. Parents hope that early music lessons, for example will build a child’s confidence. The truth, however, is that any time children are asked to do too much, too soon, they are at greater risk for feelings of failure.

A child’s time does not have to be planned to be meaningful. Remember the lazy days of summer? Some children sleep late and play with the kids across the street until it’s time to come home for dinner. However, with the majority of mothers working, fewer children enjoy that idle (空閑的) time now.

Come September, children across the country will finish a full day of kindergarten, only to attend an after-school program until 6 P.M., when a working mom or dad comes to take them home. That’s too much for a five-year old. Finances, of course, do limit some parents. But let’s be honest with ourselves – our own busy schedules, whatever they involve, are no excuse for burdening a young child’s.

1.The author holds that it’s a challenge to plan a schedule for a child mainly because _____.

A. a child’s schedule is too complex

B. activities suitable for kids are limited

C. parents are stuck in numerous choices

D. children always say no to parents’ advice

2.What the two teachers say in Paragraph 2 implies that _____.

A. children love to stay at school

B. they are popular with children

C. children dislike after-school classes

D. after-school classes are of poor quality

3.According to the author, what is the real reason for parents to send their children to after-school classes?

A. Parents want to make up for their own regrets.

B. After-school classes develop children’s potential.

C. Parents have doubt about their own ability to guide children.

D. After-school classes give parents an excuse for being absent.

4.Which of the following will the author probably agree with?

A. For children’s benefits, the earlier the better.

B. Children’s spare time should be carefully designed.

C. Idle time for children is becoming a thing of the past.

D. Parents should be forgiven if they have a good reason.,

科目:高中英語 來源:2014-2015學(xué)年山東省菏澤市高三下學(xué)期第二次模擬考試英語試卷(解析版) 題型:短文改錯(cuò)

In our life, we often regret what we did and which we couldn’t do. Actually, it doesn’t benefit us at all. As for most of us, we missed many chance to earn more money, to get a high position and to realize our dreams. We often regret that we don’t seize those opportunities, thus feel upset. Although we do know regretting the Past is no benefit, but we still can’t help doing it

To avoid the problem below, we need to pay more attention to what you are doing now, making us busier and having no time to recall the past. Moreover, we’d better set reasonably goals one by one. Only by doing so can we struggle for our future better.
