28、ually could lead to new cancer treatments.Dr. Randy Nelson, an associate professor of psychology at Hopkins, stressed at a meeting of the Society of Neuroscience that further study would be needed to confirm a connection between the length of the day, the animals immune system and cancer. More work

29、also would be needed to show that the findings could be applied to human cancer.Dr. Faye Austin, an immunologist with the National Cancer Institute in Bethesda, said: “Its a very intriguing observation that the length of exposure to light can affect the growth of a tumour. But I think that the draws

30、 really need further work to clarify the mechanics.“But Austin said the findings were surprising and important, only because they open up a new approach for research.Studies showed that stress weakened the immune system in animals. They figured that because winter is stressful, the season probably c

37、angerous place, not only because of meteors (流星) 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 essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Variou

38、s kinds of rays come through the air from outer space, but enormous quantities of radiation (辐射) 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 radiat

39、ion 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 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extrem

Missions of the Apollo flights have had to cross belts of high rad

41、iation and, during the outward and return journeys, 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 space laboratory. Rugs might help to decrease the damage done by

42、radiation, but no really effective ones have been found so far.（分数：10.00）(1).According to the first paragraph, the atmosphere is essential to man in that _.（分数：2.00）A.it protects him against the harmful rays from spaceB.it provides sufficient light for plant growthC.it supplies the heat necessary fo

46、Text 3/BThe biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this inte

47、rference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.RTCA, an organization which advises the aviation industry, has recommended that all airlines ban such devices fro

48、m being used during “critical“ stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.The difficulty is predicting how electromagnetic fields might affect an aircrafts computers. Experts know that portable devices emit radiation which
