A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.

Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights The other half spent more than fourteen days in their home areas.

The researcher took some saliva from the women's mouths to measure levels of a hormone(荷尔蒙) that increases during stress (紧张). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain's temporal lobes (脑叶).

It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.

The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.

Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.

According to the text, jet lag _________.

A. can cause difficulties in speaking

B. can make people feel tired for a few weeks

C. can be only found in flight attendants

D. can be caused by flying over several time zones

It can be inferred from the text that _________.

A. the conclusion is refused by many scientists

B. scientists fear that this research is not done properly

C. every scientific conclusion needs the support from many tests

D. the women who were examined in the research were not healthy

From the result of the research we can see that _________.

A. the women who have longer rest at home show better memory

B. the women who fly in short time have smaller right temporal lobes

C. the women who have longer flights fail the memory test

D. the women who rest more than 14 days produce less hormones

What is the subject discussed in the text?

A. The cause of jet lag.      B. A story of a group of flight attendants.

C. The importance of having enough rest after flights.

D. A research about the effects of jet lag on the brain.

A patient came to see me about the stress in her life. She described all the things she had to do －one was to make her bed－from the moment she woke up until she flew out of the door for work. I suggested she experiment by not making her bed for two weeks. She was shocked, probably thinking I’d been raised by wolves in a forest. However, she went along with my idea.

Two weeks later she went into my office beaming. She had left her bed unmade for the first time in 42 years－and nothing bad had happened. “And you know what?” she said. “I don’t dry my dishes anymore, either.”

    This woman had made two major breakthroughs (突破). One was discovering that she had choices in her life that she had never seen before. The other was giving herself permission to be less that perfect. This story shows an important principle (原理) about managing time: No one can do it all. Each of us has to make choices and accept trade – offs. The problem is, many people choose in ways that put themselves and their health last. They take better care of their houses and cars than they do of themselves. They put everyone else’s needs ahead of their own.

    So what is the solution? There’s an easy way. Decide what you want in your life, and put that first. On a daily basis, that should include regular meals, enough sleep and time with your family. Exercise, leisure, friendships and hobbies should also be regular aspects of life. The point is to do something for yourself every day. The choice is yours: whatever makes you feel good about yourself and your life. Take a nap. Take a walk. Take time to play the piano. Stop bringing your briefcase home from the office. Stop keeping your house as clean as your mother kept hers. Fill more of your time with want – to – dos instead of have – to – dos.

What is the solution to the problem of managing time?

       A．Doing more exercises every day.    B．Taking time to visit friends regularly.

       B．Most people put others’ needs ahead of their own.

       C．Most people cannot keep balance on managing time.

       D．Most people do not take time to relax themselves.

What is the author’s attitude toward people’s problems in the passage?

In the 1960s, people asked about your astrological sign(星相). In the 1990s, they wanted to know your website (网址). These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity.

Think of your home page as the starting point of your website. Like the table of contents of a book or a magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.

While web pages vary greatly in their design and content, most use a traditional magazine layout (版面设计). At the top of the page is a banner(大标题) GRAPHIC. Next comes a greeting and a short description of the site. Pictures, texts, and links to other websites follow.

Before you start building your site, do some planning. Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site. Draw a rough layout on a sheet of paper.

While there are no rules you have to follow, there are a few things to keep in mind:

Start simply If you are too ambitious (雄心勃勃的) at the beginning, you may never get the site off the ground. You can always add to your site.

Less is better Most people don't like to read a lot of text online. Break it into small pieces.

Smaller is better Most people connect to the Internet with a modem (调制解调器). Since it can take a long time to download large image files, keep the file sizes small.

Have the rights Don't put any material on your site unless you are sure you can do it legally (合法地). Learn the Net's Copyright Article for more about this.

Now it's time to roll up your sleeves and start building. Learning the Net Communities provides tools to help you build your site.

More than half of Americans do not take all their vacation days，even though they think they need one more holiday.And nearly a third of workers who take a break check their e-mails from the boss every other day and some even keep in touch hourly.

“We’re workaholics(工作狂)’，”said Samuel Nahmias.“From a general perspective，this has a lot to do with the economic situation in the US.More and more people are unemployed.”

With jobless numbers reaching 9.6 percent，people who have jobs seem to be unwilling to take time off.“It_is_not_a_great_picture and that affects vacations.People are not going on vacation as much and those who are going on vacation are being more selective about where they are going.”Nahmias explained.

Unlike European countries where four or more weeks of holiday each year is normal,27 percent of people questioned in the poll said they had 6 to 10 days of annual leave and 20 percent had less than 3 days.With more people on unemployment lists in America，those still with jobs are facing more responsibility at work，which is reflected in their lack of time off.

The majority of workers who did not take time off mentioned too many responsibilities or stress at work，while some people said they simply did not have time to plan a holiday.“People are more conscious of what they are doing and when they are going on vacation because they don’t want to look bad in this situation，”Nahmias explained.

Technology is also playing a part with smartphones enabling workers to keep in contact in ways that were not possible before.It has to do with technology and the level of concern about what is going on in the office.

2．What does Nahmias mean by saying the underlined words in Paragraph 3?

A．Travelling makes people unwelcome.

B．People are unwilling to go on short vacations.

C．The economic situation remains at a low point.

C．Americans are more hard-working than Europeans

D．More people are losing their jobs in Europe
