33、used 75 Common cold is a viral infection that starts in the upper respiratory tract, sometimes spreads to the lower structures, and may contribute secondary infections in the eyes or middle ears. The main differences between the common cold and other respiratory infections are the absence of fever a

34、nd the relative mildness of the symptoms. About 200 different strains of virus are capable of producing colds. Frequently two or more different viruses can be isolated during a single episode. The cold is spread by person-to-person contact. People can carry the virus and communicate it without thems

35、elves experiencing any of the symptoms. Incubation is short usually one to four days. The viruses start spreading from an infected person before the symptoms appear, and the spread reaches its peak during the symptomatic phase. The incidence of colds peaks during the autumn, and minor epidemics comm

36、only occur throughout the winter. The reason for this incidence is unknown; it may not stem mainly from stresses imposed by chilly weather but rather result from the greater amount of time spent indoors, which increases the likelihood of close contact with those persons carrying cold viruses. Pathol

37、ogic changes occurring in the mucous membrane that lines the nose, the nasal sinuses, the nasoharynx, and other upper respiratory passages may include tissue swelling, congestion of blood, and oozing of fluids. During the acute phase of the disease, the respiratory secretions are altered by increase

38、 in serum proteins. Parts of cells may also be found in the fluids. Tissue repair is rapid and seems complete, although a relationship might exist between colds and more serious respiratory conditions. Cold symptoms vary from person to person, but in the individual the same symptoms tend to recur in

39、 succeeding bouts of infection. Manifestations may include sneezing, headaches, fatigue, chilling, sore throat, inflammation of the nose (rhinitis;, and nasal discharge. There is usually no fever. The symptoms usually last for only a few days. The nasal discharge is the first warning. The secretions

40、 become watery, clear, and excessive. Later, they thicken, increase in mucus and pus content, and may colour a yellow-green, with traces of blood. Coughing can be dry or produce amounts of mucus. Other more serious diseases with similar general symptoms may be mistaken for a cold; some of these are

41、tuberculosis, bronchitis, lung abscesses, and inflammation around the heart. Treatment is, in most instances, directed toward allaying of symptoms, coupled with rest and adequate fluid intake. Occasionally antibiotics are given to prevent secondary infections. 76 According to this passage, common co

42、ld is （ A） a hereditary disease. （ B） generally accompanied with mild fever. （ C） a kind of popular respiratory infection. （ D） caused by spending a lot of time outdoors in chilly weather. 77 The second paragraph is mainly about_of colds. （ A） the causes （ B） the definition （ C） the incubation （ D）

43、the spreading 78 What kind of person is most likely to catch a cold? （ A） The person who has a mild fever for a few days. （ B） The person who carries viruses capable of producing colds. （ C） The person who spends most of his time indoors. （ D） The person who spends most of his time outdoors. 79 Whic

44、h of the following is NOT a treatment to cold? （ A） More rest. （ B） Drink enough water. （ C） Take antibiotics. （ D） Stay indoors more. 80 Which of the following statements is TRUE? （ A） Common cold is the first warning of bronchitis. （ B） Tuberculosis is believed to have developed from common cold.

45、（ C） The application of antibiotics is the only effective means in the treatment of common cold. （ D） Radical surgery is never needed in the treatment of common cold. 80 Can computers reason? Reasoning requires the individual to take a given set of facts and draw correct conclusions. Unfortunately,

46、errors frequently occur, and we are not talking about simple carelessness as occurs when two numbers are incorrectly added, nor do we mean errors resulting from simple forgetfulness. Rather, we have in mind errors of a logic nature those resulting from faulty reasoning. Now, or at least soon, comput

47、ers will be capable of error-free logical reasoning in a variety of areas. The key to avoiding errors is to use a computer program that relies on the last two decades research in the field of automated theorem proving. AURA (Automated Reasoning Assistant) is the program that best exemplifies this us

48、e of the computer. AURA solves a problem by drawing conclusions from a given set of facts about the problem. Program does not learn, nor is it self-analytical, but it reaches logical conclusions flawlessly. It used various types of reasoning and, more important, has access to very powerful and sophi

49、sticated logical strategies. AURA seldom relies on brute force to find solutions. Instead it solves almost all problems by using sophisticated techniques to find a contradiction. One generally starts with a set of assumptions and adds a statement that the goal is unreachable. For example, if the problem is to test a safety system that automatically shuts down a nuclear reactor when instruments indicate a problem, AURA is told that the syst
