Life has changed in
Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30. It has sent a wave of alarm around the world. Governments are trying to find ways to prevent further outbreaks. The World Health Organization has raised its swine flu global threat level to five out of six.
People may be familiar with bird flu. but they know little about swine flu.O Swine flu is a contagious (传染性的) respiratory (呼吸的) disease in pigs. It is caused by a type-A influenza virus.
Humans can also catch swine flu. The virus causes regular outbreaks in pigs, but people usually do not catch it. However, there have been cases of the virus spreading to people, and then from one person to another.
The symptoms of swine flu are similar to the common flu. They include fever, lethargy (无精打采的), lack of appetite, coughing, runny nose, sore throat, nausea (恶心), and vomiting (呕吐). The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known.
The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then "touching their mouth, nose or eyes.
There are medicines to treat swine flu. Doctors suggest using anti-viral drugs. They keep the virus from reproducing inside the body.
Although there are no vaccines (疫苗)for it now, several everyday steps can help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it.
People may worry that they will get swine flu from eating or preparing pork. In fact, you cannot catch the virus from pork products if they have been properly prepared and cooked. Cooking food at temperatures of 71oC kills the virus.

小学生10分钟应用题系列答案Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary(当代的) societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.
When older people become senile (衰老的) or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (疗养的) hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the dying in which “care” is given by poorly paid, overworked, and under skilled personnel.

The greatest recent changes have been in the lives of women, during the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty five and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances （家用电器）and convenience foods.
This important change in women’s way of life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full time job. However, when they married, they usually left work at once and never returned to it. Today the school leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards, return to full or part-time work. Such changes have led to a new relationship in marriage, with both husband and wife accepting a greater share of the duties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the home, according to the abilities and interest of each them.
