Put your kid on a greeting card.Here is how: simply take some pictures with a regular camera, and then ask the photo service to develop them digitally (数字化).For a small fee, you’ll receive your photos on a desk.Put that into your computer and, with a few clicks of the mouse, you can view your photos on the screen.With a few more keystrokes, you can attach the photos to email and send them to friends and relatives worldwide.
Sign on to one or several greeting card’s Websites (http://www.cardcentral.net/ is an index of more than 1200 electronic card sites) and create an electronic birthday or holiday card.Using your digital photos, you can paste your grandchildren onto the cover.

Call Australia for free.To have a telephone conversation over the Internet, the person you want to talk to no longer needs a computer.Now all you need to talk to someone in Sydney is one computer with speakers, a microphone, a sound card and some software (available at http://www.vocaltec.com/ or Mricrosoft.com).Typically, you’ll pay a monthly fee (usually under $20) to a service provider, but after that, the calls themselves are local.Sound quality is the same as that of a cell phone.
Even if you don’t have a computer, you can still use the Web to reduce your long distance phone costs.Some companies offer a service that lets you use an ordinary phone to call another ordinary phone, but charge only a few cents per minute for US calls, because they send them through the Internet.

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

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 new research has uncovered that culture is a determining factor when interpreting facial emotions (情感).The study reveals that in cultures where emotional control is the standard, such as Japan, focus is placed on the eyes to interpret emotions.Whereas in cultures where emotion is openly expressed, such as the United States, the focus is on the mouth to interpret emotion.
"These findings go against the popular theory that the facial expressions of basic emotions can be universally recognized," said University of Alberta researcher Dr.Takahiko Masuda."A person's culture plays a very strong role in determining how they will read emotions and needs to be considered when interpreting facial expression."
These cultural differences are even noticeable in computer emoticons (情感符号), which are used to convey a writer's emotions over email and text messaging.The Japanese emoticons for happiness and sadness vary in terms of how the eyes are drawn, while American emoticons vary with the direction of the mouth.In the United States the emoticons :) and :-) show a happy face, whereas the emoticons : ( or : -( show a sad face.However, Japanese tend to use the symbol ( ' ' ) to indicate a happy face, and ( ;_; )to indicate a sad face.
"We think it is quite interesting and appropriate that a culture tends to mask its emotions.The Japanese would focus on a person's eyes when determining emotion, as eyes tend to be quite subtle (微妙的)," said Masuda."In the United States, where open emotion is quite common, it makes sense to focus on the mouth, which is the most expressive feature on a person's face."
The text mainly tells us that __________.
A.cultural differences are expressed in emotions
B.culture is the key to interpreting facial emotions
C.different emoticons are preferred in different cultures
D.people from different cultures express emotions differently
