the West Coast. Ever since she was a young girl, Mrs. Cox had wanted to become a teacher. She has taught eight years now and hasn't changed her mind.

After she graduated from high school, Mrs. Cox went on to college. Four years later, she received her bachelor's degree (B. A. ) in English and her teaching certificate. Then she was qualified to teach in the secondary schools of her state. In the summers, Mrs. Cox takes more classes. Someday she hopes to get a master's degree (M. A. ). With an M. A. , she will receive a higher salary.

The school day at Mrs. Cox's high school, like that in many high schools in the United States, is divided into six periods of one hour each. Mrs. Cox must teach five of these six periods. During her free period, which for her is from 2 to 3 p.m. , Mrs. Cox must meet with parents, order supplies, make out examinations, check assignments, and take care of many other things. In short, her free period isn't really free at all. Mrs. Cox works steadily from the time she arrives at school in the morning until the time she leaves for home late in the afternoon.

First two hours , now three hours-this is how far in advance authorities are recommending people show up to catch a domestic flight , at least at some major U.S. airports with increasingly massive security lines.

Americans are willing to tolerate time-consuming security procedures in return for increased safety. The crash of Egypt Air Flight 804,which terrorists may have downed over the Mediterranean Sea ,provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans' economic and private lives, not to mention infuriating.

Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons---both fake and real-past airport security nearly every time they tried .Enhanced security measures since then, combined with a rise in airline travel due to the improving Chicago's O'Hare International .It is not yet clear how much more effective airline security has become-but the lines are obvious.

Part of the issue is that the government did not anticipate the steep increase in airline travel , so the TSA is now rushing to get new screeners on the line. Part of the issue is that airports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this.

There is one step the TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA wants to enroll 25 million people in PreCheck.

It has not gotten anywhere close to that, and one big reason is sticker shock. Passengers must pay $85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.

The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.

laziness is immoral, that it is wasteful, and that lazy people will never gain anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons. Some people who appear to be lazy are suffering from much more serious problems. They may not trust their fellow workers and they are unable to join in any group task for fear of being laughed at or for fear of having their ideas stolen. These people who seem lazy may be affected by a fear of failure that prevents successful work. Some people are so busy planning great deals that they are unable to deal with "easier" work on hand. Still others are not avoiding work; strictly speaking, they are simply putting off their work. aziness, however, can actually be helpful. Some people may look lazy while they are really thinking, planning and researching. We should all remember that great scientific discoveries happened by chance. Newton wasn't working on the farm when the apple hit him and he devised the theory of gravity. All of us would like to have someone "lazy" build the car we buy, particularly if that "laziness" were caused by the worker's taking time to check each step of his work and to do his job right. And sometimes, being "lazy" — that is, taking time off for a rest—is good for the overworked students or executives. Taking a rest can be particularly helpful to the sportsman who is trying too hard or the doctor who is simply working himself overtime too many evenings in the hospital. So be careful when you want to call someone lazy. That person may be thinking, resting, or planning his or her next work.

sage. Living in a time when an ever-increasing number of news providers push a constant stream of headlines at us every day, people cannot say they do not feel overwhelmed. But what of its the ways we choose to read the news that make us feel overwhelmed？ An interesting new study conducted by Avery Holton and Iris Chyi from the University of Texas looks at the factors that contribute to the concept of information overload. They surveyed more than 750 adults on their digital consumption habits and perceptions of information overload. What the findings suggest, Holton said, is that the news platforms a person is using can play a bigger role in making him feel overwhelmed than the sheer number of news sources being consumed. So even if you read The Huffington Post and The New York Times in a day, you may not feel as drowned with news ff you read on your phone instead of on your desktop. The more contained, or even constrained, aplat form. feels, the more it can contribute to people feeling less overwhelmed, Holton said. That may also explain why people have feelings of being overwhelmed by Facebook, which like reading on the web, can be a bottomless hole of stories, videos, and endless links. But it doesnt explain why people in the survey had different feelings towards Twitter, which can also be a stream of links. One possible explanation is whether you define yourself" as a news fan. The survey asked people to report. how much they enjoyed keeping up with the new——people who said they did had less of a perception of information overload. If youre the type of person who wants to follow news during the day, its likely you have an established routine and a set of sites you check regularly. You also may not need as much context around the news. All of that would make Twitter a good source for you. Conversely, if youre more passive about following the news, you might need to make more , of an effort to find the right sources or find background or contextual information, which could lead to feelings of being overloaded, Holton said. "Knowing what youre looking for can decrease overload or perceptions of overload. So can constant engagement," he said. The new study conducted by Avery Holton and Iris Chyi

A.examines how news providers take advantage of headlines

B.studies what can lead to the concept of information overload
