Of course ,modern postal services now are much more developed and faster ,depending as they do on cars and planes for delivery .Yet they are still too slow for some people to send urgent documents and letters. The invention of the fax machine increased the speed of delivering documents even more .When you send a fax ,you are sending a copy of a piece of correspondence to someone by telephone service .It was not until the early 1980s that such a service was developed enough for businesses to be able to fax documents to each other.

Ques:Article: Grandparents Answer a Call As a third generation native of Brownsville, Texas, Mildred Garza never pleased move away. Even when her daughter and son asked her to move to San Antonio to help their children, she politely refused. Only after a year of friendly discussion did Ms Gaf finally say yes. That was four years ago. Today all three generations regard the move to a success, giving them a closer relationship than they would have had in separate cities. No statistics show the number of grandparents like Garza who are moving closer to the children and grandchildren. Yet there is evidence suggesting that the trend is growing. Even President Obama's mother-in-law, Marian Robinson, has agreed to leave Chicago and into the White House to help care for her granddaughters. According to a study grandparents. com, 83 percent of the people said Mrs. Robinson's decision will influence the grandparents in the American family. Two-thirds believe more families will follow the example of Obama's family. "In the 1960s we were all a little wild and couldn't get away from home far enough fast enough to prove we could do it on our own,"says Christine Crosby, publisher of grate magazine for grandparents. "We now realize how important family is and how important to be near them, especially when you're raising children." Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder. Question: What did Crosby say about people in the 1960s? Yes or no, is the answer "They wanted to live away from their parents."?

Ans:Yes

Ques:Article: Look closely at ,your hands-are they clean? It doesn't matter how many times you was your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive. Now, scientists say the microbes that live on our hands could be used in a surprising way: fighting crime. When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal. But according to a recent study, investigators could even use microbes to help break a criminal case. Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint. The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find. And policemen use forensics such as studying fingerprints to identify the criminal. "Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists. "You can't sterilize(......) a surface just by wiping it off. " His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards. But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool. Question: The main idea of the passage is about _ . Yes or no, is the answer "the usefulness of microbes"?

Ans:No

Ques:Article: "You're going to the United States to live? How wonderful! You're really lucky!" Does this sound familiar? Perhaps your family and friends said similar things to you when you left home. But does it seem true all the time? Is your life in this new country always wonderful and exciting? A great many facts show that it's not easy for newcomers to adjust to life in a new culture. They have to experience culture shock. What causes culture shock? Maybe the weather is unpleasant. Perhaps the customs are different. Perhaps the public service systems such as the telephone, post office, or transportation are difficult to figure out and you make mistakes. The simplest things seem difficult. The language may be difficult. The food may seem strange to you. If you don't look similar to the natives, you may feel strange. You may feel as if everyone is watching you. In fact, you are always watching yourself. Everyone experiences culture shock in some form or another. But culture shock comes as a surprise to most people. A lot of the time, the people with the worst culture shock are the people who never had any difficulties in their own countries. They were active and successful in their community. They had hobbies or pastimes which they enjoyed. When they come to a new country, they do not have the same positions or hobbies as they already had in their countries. They find themselves without a role, almost without an identity. They have to build a new self-image. Culture shock produces a feeling of disorientation , which may be homesickness, imagined illness, or even paranoia . When people feel the disorientation of culture shock, they sometimes feel like staying inside all the time. They want to protect themselves from the unfamiliar environment. They want to create an escape within their room to give themselves a sense of security. This escape does solve the problem of culture shock for the short term, but it does nothing to familiarize the person more with the culture. Familiarity and experience are the long-term ways to... Question: The best way for the newcomers to overcome culture shock is _ . Yes or no, is the answer "to adapt themselves to the new environment"?
