问题     In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenza-like (像流感的) cases. Influenza is sometimes called "flu" or a bad cold". He took samples from the throats of patients and in his hospital was able to find the virus (病毒) of this influenza.
    There are three main types of the influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he did not know the subgroup. He reported the outbreak to the World Health Organization in Geneva. W.H.O. published the important news alongside reports of a similar outbreak in Hong Kong, where about 15-20% of the population had become ill.
    As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs used against all the known sub-groups of type A virus on this virus. None of them gave any protection. This then, Was something new: a new influenza virus against which the people of the world had no ready help whatsoever.
    Having isolated the virus they were working with, the two doctors now conducted tests on some specially selected animals, which contact influenza in the same way as human beings do. In a short time the usual signs of the disease appeared. These experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply "Asian" flu.  
What is the writes’s attitude towards the Asian flu?
选项 A、He simply reports the disease objectively.
B、He is worried about the spread of the disease.
C、He is disappointed at the tests of the London doctors.
D、He believes that the disease will soon be controlled.
答案A
解析 从全篇来看，作者只是报道了这种流感的出现、原因及相关实验和发现。他并没有表示担心、失望或失去对这种流感控制的信心。
