the number of people who died of the flu in the world is conservatively estimated to be 30 million, and some estimates are as high as 100 million.the number of people infected is higher, estimated to be close to half of the world's population.the approximate death toll of major European and American countries is: million in Britain, million in France, 250000 in Germany, million in the United States, 50000 in Canada and nearly 260000 in Spain.in this disaster, the age distribution of the dead population shows a W-curve, that is, the mortality rate of young and middle-aged people aged 15-45 is very high, which directly affects the combat effectiveness of the front line. For the rear area and other countries, it also leads to the loss of a large number of labor force. As a result, there is a lack of workers in enterprises, a lack of personnel in the public sector, a significant reduction in business activities, and a significant impact on the economy and society Impact.different countries have taken different countermeasures.
for example, in some states of the United States and Australia, measures taken include isolation of patients, prohibition of public gatherings, closure of theaters, schools, libraries, billiards rooms and other places where people gather, asking people to keep a certain distance in churches, bars, restaurants, cafes, retail stores, etc., enterprises stagger the time of going to and from work to reduce centralized travel, and public service personnel must Wear a mask.in the UK, the government isolated the patients, issued various pamphlets, notices and flyers, urged the public to avoid contact with the patients, required regular ventilation and disinfection in cinemas and other entertainment places, recommended that people keep indoor ventilation and cleaning, wear masks and wash hands frequently, but did not close schools, theaters and other public entertainment places, and industrial and commercial activities were carried out as usual.because the surface area of the ball is the smallest but the tension is the largest when the two volumes are the same.
it can be concluded that word meaning is the smallest semantic unit used independently, and the structure of word meaning sphere is compact, solid, flexible and with high surface tension.when the surface areas of the two objects are the same, the volume of the ball is the largest.it can be concluded that the structure of semantic sphere is rich in connotation, huge in size, strong in expanding ability and powerful in function.fourth, the word meaning ball is very similar to the egg, which contains vitality.
the egg is composed of three parts: "eggshell, egg white and egg yolk", which are interdependent with each other. The word meaning ball is also composed of three elements: "object meaning, attribute meaning and attribute value meaning", which are also interdependent with each other. When the egg meets the right temperature, it can hatch the chick, and when the three elements of the word meaning ball structure meet the right semantic assignment, it can also produce sentences.(the author is the director of the National Social Science Foundation Project "Research on Modern Chinese word meaning based on syntax semantic interface" and associate professor of Hubei University) (editor in chief: Sun Shuang and AI Wen)
