B
Fever has usually been regarded as a threat to health.However,no one has actually proved that fever is dangerous.This fact attracted the attention of Matthew J.Kluger.Imagining that fever might not be as harmful as it had been supposed,Kluger set up a series of experiments with lizards(蜥蜴).
What Kluger and his team did his team did in their first experiment was simple.They put some lizards in a sand-box,one end of which was heated to 44℃,while the other was at a room temperature.It was found that the lizards moved form one part of the box to the other in order to keep a constant temperature of about 38℃.Having shown that normal lizards regulate(调节) their own temperature,Kuger,in a second experiment,then set out to show that lizards,like most other animals,develop fever when infected.This was done by making lizards infected with bacteria (细菌) that were known to cause disease.As the team expected,the infected lizards remained longer in the heated part of the box,until they had raised their body temperatures to two or three degrees above normal.In other words,the sick lizards gave themselves fever.
In a third experiment,the team observed the effect of temperature on the survival of the lizards.One group of infected lizards was given a fever - suppressing(退烧) drug.The other group was given no drug and ran a fever,that is to say,they kept a highter temperature for four or five days before seeking a cooler environment.The results were impressive.Of those which raised their body temperature,all but one remained alive.Of those given the fever - suppressing drug,more than half died.Similar results have since been produced in other animals.For example,infeced fish swim to warmer water,and will die if not allowed to do so.
An important conclusion can be drawn from these experiments.As Kluger points out,lizards have been on earth for hundreds of millions of years.It is reasonable to suppose that a response that is so old has been kept by nature for some purpose.It would appear, therefore, that fever does not make disease worse.Rather it its part of the mechanism(机能) by which infection is controlled.
60.In his experiments,Kluger was hoping to prove that fever ________.
A.is not harmful to lizards
B.is not necessarily bad
C.is necessary for both humans and animals
D.has the same effect on humans and animals
61.The lizards put in the sand - box in the first experiment _____.
A.had a fever B.were not sick C.recovered from disease D.died of heat
62.In the third experiment,the lizards given a fever - suppressing drug died because _____.
A.they had no more fever that they needed
B.they were normal ones and had no fever
C.the drug had no iffect on sick lizards
D.the drug made their body temperature too low
63.How would you understand the underlined words"a response" in the last paragraph?
A.Gause of disease. B.Recovery from disease.
C.Relationship between living D.Natural defense in the body against disease.

There was great excitement on the planet of Venus(金星) this week.For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof.Manhattan, who first discovered it with his telescope 20000 light years ago).
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth.A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week’s satellite landing,” Prof.Zog said, “that there is no life on Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there.For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” [来源:高考资源
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo.You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink.This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof.Zog replied.
1.During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.
A.the feasibility of landing a satellite on Earth
B.the possibility of making a first-rate flying saucer
C.the feasibility of sending a Venus Being to Earth
D.the possibility of directing a flying saucer into Manhattan
2.According to Prof.Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.
A.they need it in their way to the planet of Earth
B.the Earth’s atmosphere is filled with deadly gases
C.there is a low level of oxygen for Venusians
D.there is no air on the planet of Earth
3.The “dark black cloud” on the photo refers to ____.
A.the polluted air hovering over the surface of Earth
B.the mass of tiny drops of water floating above Earth
C.the mass of small things moving through the air
D.the dark clouds gathering before a storm breaks
4.The author wishes to call our attention to the fact that ____.
A.that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this
B.that there is a point in spending billions to land a flying saucer on Earth
C.that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.
D.that it is difficult if not altogether impossible, to land a manned flying saucer on Earth
