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(cè)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.

Culture and Cuisine

The United States is known for jazz and blue jeans.But travel to Paris and ask your average French citizen about American cuisine (烹飪) and he’s likely to answer,“ McDonalds.” Ask the same thing of any American citizen on any American street and I’m afraid you’d get the same answer,or something close to it.

Hamburgers and hotdogs and fries are all fine,but with American malls and other outlets standardizing everything from clothing to food,the sad truth is that American cuisine is becoming more homogeneous―all the same―no matter where you live.True,many Americans are eating more varied foods these days,but these are largely the cuisines of immigrant groups,and they are quite likely to be affected by homogenization of American cuisine.

So what exactly is American cuisine? Well,to some extent it is a reflection of our melting pot culture,meaning that Europeans made huge contributions in the form of wheat,dairy products,pork,beef and poultry.But American cuisine also includes products that once were known only to the New World,including potatoes,corn,pumpkin,sweet potatoes,and peanuts.

The one region of the country where you still find all these things in daily use is the Deep South.The South lost the Civil War,but children of the southerners are winning the battle to preserve and advance their cooking traditions—and in this case one of the few cuisines can truly be called American,which is why we’re pleased to have Low Country cuisine in this issue of food creation.That’s right,grits and gravy are back in a big way in cities like Charleston and Savannah.Truth is,they never really left,but up until a decade ago Low Country cuisine was more common at home than in restaurants.

In fact,a large number of tourists now go to the lower Atlantic region in order to experience this extraordinary cuisine for themselves.Time will tell whether Low Country cuisine becomes popular in other regions of the country in the way that,say,Italian cuisine has,but it’s amazing and heartening to see one of our true cultural treasures enjoying renewed popularity in these increasingly homogeneous times.

1.According to the passage,American cuisine impresses people as being _______.

A.dull and changeless

B.rich and various

C.popular and delicious

D.disagreeable and unpleasant

2.It can be seen that the writer feels regretful that _______.

A.cuisines of other countries play a more important role in America

B.American cuisine has become increasingly lacking in variety

C.American cuisine tends to vary because of immigration

D.American cuisine is being changed by foreign cuisines

3.From the passage,we know that grits and gravy _______.

A.were cooked with new materials after the Civil War

B.a(chǎn)re gaining popularity in the south of America

C.were more popular over ten years ago

D.a(chǎn)re seldom served in restaurants

4.What’s the writer’s attitude towards the renewal of Low Country cuisine in America?

A.Concerned and cautious.

B.Hopeless and doubtful.

C.Positive and supportive.

D.Critical and disapproving.
