　　Everybody may have seen the film “Death on the Nile (n. 尼羅河)”, but nobody can imagine that the writer of the story, Agatha Christie, saved a baby in a most unusual way.

　　In June 1977, a baby girl became seriously ill in Deleville. Doctors there were unable to find out the cause of her illness, so she was sent to a famous hospital in London, where there were many excellent doctors. The baby was so seriously ill that a team of doctors hurried to examine the baby without delay. The doctors, too, were puzzled by the baby’s illness and they also became discouraged. Just then a nurse asked to speak to them.

　　“I think the baby is suffering from thallium (n. 鉈) poisoning. ” said the nurse. “A few days ago, I read a story ‘A Pale Horse’ written by Agatha Christie. Someone uses thallium poison, and all the symptoms are written in the book. They are exactly the same as the baby’s.”

　　“You’re very good at observing things,” said a doctor, “and you may be right. We’ll carry out some tests and find out whether the cause is thallium poisoning or not.”

　　The tests proved that the baby had indeed been poisoned by thallium. Once they knew the cause, the doctors were able to give her correct treatment. The baby soon got well and was sent back to Deleville A week later, it was reported that the poison might have come from an insecticide (n. 殺蟲劑) used in Deleville.

　　The baby was sent to a hospital in London because______.

　　Aher parents were living in London then

　　Bthe hospitals in Deleville were full at that time

　　Cshe was the daughter of a famous doctor in London

　　Ddoctors in Deleville were not sure about the cause of her illness

　　Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

　　Radiation is the greatest known danger to explorers in space, The unit of radiation is called “rem” Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed(畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

　　根據(jù)以上內(nèi)容，回答下列各題。

　　In which way is the atmosphere necessary to man according to the first paragraph?

　　Ait supplies the heat necessary for human survival

　　Bit provides sufficient light for plant growth

　　Cit protects him against the harmful rays from space

　　Dit screens off the falling meteors
