共用题干第一篇UlcersEven though ulcers appear to run in families,lifestyle plays more of a role than genetic （基因的）factors in causing the illness, according to a report in the April 13th issue of Journal of Internal Medicine. In particular,smoking and stress in men and the regular use of pain-releasing medicines in women were linked with an increased risk of developing an ulcer（溃疡）.Overall,61% of ulcer risk appears to be due to environmental factors,such as smoking,and the remaining 39% is due to genes,according to Dr. lsmo Raiha of the University of Turkey and colleagues at the University of Helsinki,Finland.Some researchers had suggested that families may spread Helicobacteria pyloni（幽门螺旋菌）, the bacteria（细菌）that can cause ulcers. However, the new study suggests this is unlikely,according to the report.Raiha and colleagues studied data from more than 13,000 pairs of twins to examine the roles of genetic and environmental factors in the origin of ulcer. Both twins were more likely to develop an ulcer if the pain were genetically the same as compared with a pair of fraternal（由两受精卵发育而成的）twins , suggesting that there must be some genetic susceptibility（敏感性）to ulcer development.However,the risk was no greater in twins living together compared with twins living apart,suggesting that shared exposure to H.pyloni was not to blame." Environmental effects were not due to factons shared by family members,and they were related to smoking and stress in men and the use of pain-releasing medicines in women,"the authors write in their report. Raiha and colleagues found environmental effects related to all the following factors EXCEPTA:the regular use of pain-releasing medicines.B:shared exposure to H.pyloni.C:smoking.D:stress.
共用题干第二篇Natural MedicinesSince earliest days,humans have used some kinds of medicines.We know this because humans have survived.Ancient treatments for injury and disease were successful enough to keep humans from dying out completely.They were successful long before the time of modern medicine.Before the time of doctors with white coats and shiny（发亮的）instruments. Before the time of big hospitals with strange and wonderful equipment.Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospi- tals.Yet injuries are treated.And diseases are often cured.How?By ancient methods.By medicines that might seem mysterious , even magical（有魔力的）.Traditional medicines are neither mysterious nor magical, however.Through the centuries, tribal（部族的）medicine men experimented with plants. They found many use- ful chemicals in the plants.And scientists believe many of these traditional medicines may provide the cure for some of today's most serious diseases.Experts say almost 80% of the people in the world use plants for health care.These natural medicines are used not just because people have no other form of treatment.They are used because people trust them. In developed areas,few people think about the source of the medicines they buy in a store.Yet many wide- ly-used medicines are from ancient sources,especially plants.Some experts say more than 25% of modern medicines come,in one way or another,from nature.Scientists have long known that nature is really a chemical factory.All living things contain chemicals that help them survive.So scientists' interest in traditional medicine is not new.But it has become an ur-gent concern.This is because the earth's supply of natural medicines may be dropping rapidly. It is believed by scientists that traditional medicines__________.A:can cure all kinds of diseasesB:may cure some of today's most serious diseasesC:are no longer useful for modern menD:are too cheap to be useful
