題目列表(包括答案和解析)

In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenzalike 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 seleceted 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 public, called it simply “Asian flu”.

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

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”a new one

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

The Asian flu virus ____.       [    ]

The Intel Science Talent Search is the top science competition for high school students in the US. The 40 finalists were honored in Washington last week. They met with scientists and politicians. President Obama welcomed them to the White House.
These 40 students were selected from almost 2,000 contestants nationwide. They had to present original research to be judged by professional scientists. The students showed their research projects on large posters. The winners were announced on March 15th, 2011.
Wendy Hawkins is executive director of the Intel Foundation, who says the 40 finalists represented excellence across many areas of science.
Selena Li is from Fair Oaks, California. She wanted to find a more effective treatment for liver cancer. She began her research four years ago. A scientist at the University of California, Davis, taught her how to design and do experimental work in the laboratory. Ms. Li placed 5th in the Intel Science Talent Search and was awarded 30,000 dollars.
Scott Boisvert lives near Phoenix, Arizona. He began using a laboratory at the University of Arizona at the age of 14. Over four years, he completed a project studying a fungus(真菌) linked to the decrease in amphibians(兩棲動物)around the world. He was trying to find out if different chemicals and substances in the water could kill the fungus. He collected and tested water samples across Arizona. He says, “My results were able to identify a list of chemicals that were significant in the growth and in the movement of the fungus.” He placed10th in the Intel competition and was awarded 20,000 dollars.
Evan O’Dorney of Danville, California, won the top award of 100,000 dollars in this year’s Intel Science Talent Search. For his mathematical project, he compared two ways to estimate the square root of an integer (整數(shù)) , a number with no fractional parts.
Wendy Hawkins at the Intel Foundation says these young people represent the next generation of scientists who will help shape America’s future.
【小題1】According to the passage, if you want to win the Intel Science Talent Search, you must________.

A.have high academic achievement
B.be excellent in all areas of science
C.offer original research
D.do many experiments in a university lab
【小題2】Who will be probably engaged in math study in the future and become a mathematician?
A.Wendy Hawkins.B.Selena Li.
C.Scott Boisvert.D.Evan O’Dorney
【小題3】Which statement is TRUE according to the passage?
A.Scott Boisvert found a new fungus linked to the decease in amphibians.
B.The 1st, 5th and 10th students in the competition come from California.
C.Scott Boisvert is the youngest winner among the 40 students.
D.The Intel Science Talent Search is an intense competition.
【小題4】The Wendy Hawkins’s attitude to these 40 finalists is ______.
A.criticalB.negativeC.positiveD.mixed
