The Chinese have used a method called acupuncture to help perform operations for about 4,000 years without putting the patient to sleep. This involves inserting（插入）flexible needles （针）into certain parts of the body. The needles used are available in a number of stores in China and everyone may buy them.

To learn how to use needle takes about one month of training. But to be skillful requires greater time. The person who performs the acupuncture knows how to insert the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. The needles are not necessarily inserted near the place where the pain is to be prevented. In the past, a particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.

Today the Chinese doctors are trying to learn more about acupuncture. They are trying to develop a convincing theory to explain how the needles work in preventing pain, or, why a needle in the wrist（手腕）, for example, would prevent the pain in the area of the mouth.

A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation whereas（然而，反之） the chemical may make the patient sick for a few hours or a day.

It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.
According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract（呼吸道）, leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.
However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”
In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.
Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”
Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.

Mr. Smith had neither wife nor children. He liked nothing but drinking. He almost spent all of his money with drinks. Sometimes he went hungry, but he had to borrow some money to buy some food. One evening he met a friend of him in the street. The man invited him to have dinner in a restaurant. He was very happy that he drank too much. His friend stopped a taxi and ask the driver to take him home. Soon they reached in the door of his house. The driver drove away. But Mr. Smith couldn't insert the key into the keyhole. Just then a policeman went up, offering to help him but he refused, saying “The house is circled now. If you can keep it moving, I can open the door.”
