3、Although we already know a great deal about flu, and although the World Health Organizations is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.  

There are three kinds of flu virus, known as A, B and C. flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies （抗体） which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可变性） is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence （病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters （遇到）. Scientists, however, have a reliable general picture of the world situation.

2、A gentle breeze blew through Jennifer’s hair. The golden red sun was setting. She was on the beach, looking up at the fiery （火红的） ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.  

The atmosphere relaxed her. After all she had been through, this was what she needed. “It’s getting late,” she thought, “I must go home. My parents will be wondering where I am.”  

She wondered how her parents would react, when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.  

It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... It all seemed deserted. She couldn’t understand what was going on.

She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: “Dear Ellen, there is some coffee ready. I went looking.” Ellen was her mother but ― where was she? On the right side of the hallway was her parents’ room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn’t slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different... she wasn’t in her mother’s room and she wasn’t wearing the old clothes she ran away in. She was in her cozy bed in her pajamas （睡衣）.  

It felt so good being back home. Suddenly she heard a voice, “Are you feeling better now, dear? You know you got us very, very scared.”
