        1. In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenza like cases. Influenza is sometimes called“flu”or a“bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus(病毒)of this influenza.

            There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups(亞群).At the hospital the doctor recognized that the outbreak was because of a virus-group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W.H.O.published the important news together with reports of the same kind of 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 to test them. They found that they could reproduce themselves at a very high speed. Continuing their careful tests, the doctor checked the effect of medicine used against all the known sub-groups of type A virus. On this virus, none of them was of any use

            Having separated the virus, the two doctors now made tests on some selected animals. In a short time the usual signs of the disease appeared. These experiments showed that the new virus spread easily, but that it was not a killer. Scientists, like the general pubic, it simply“Asian flu”.

          (1) The Asian flu mentioned in the passage ________.

          [  ]

          A.had something to do with a virus group B

          B.was reported to W.H.O.in Geneva by a doctor in Hong Kong

          C.broke out not only in Singapore but also in Hong Kong

          D.was taken from the throats of the patients in a hospital in Singapore

          (2) London doctors considered ________.

          [  ]

          A.Asian flu as a bad cold

          B.there were three main types of influenza

          C.it was necessary to test the other groups of virus besides group A

          D.the influenza called“Asian flu”is a new one

          (3) The Singapore doctor helped the world by _______.

          [  ]

          A.making those with Asian flu well again

          B.killing the virus that caused Asian flu

          C.finding the sub-group of the virus

          D.reporting the outbreak of Geneva

          (4) The Asian flu virus _______.

          [  ]

          A.was a killer

          B.was very weak

          C.could reproduce very quickly

          D.died very fast

          (5) We can draw a conclusion that ________ from this paragraph.

          [  ]

          A.careful observation and research can make a new discovery

          B.we must stop us from catching Asian flu

          C.doctors should pay attention to patients

          D.practice makes perfect
