共用题干Natural Medicines
Since earliest days,humans have used some kinds of medicines.We know this because hu-mans have survived .Ancient treatments for injury and disease were successful enough to keep hu-mans 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 ex- pensive hospitals.Yet injuries are treated.And diseases are often cured.How?By ancient meth- ods. By medicines that might seem mysterious, even magical(有魔力的).Traditional medicines are neither mysterious nor magical,however.
Through the centuries, tribal(部落的)medicine men experimented with plants. They found many useful 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 be-cause people trust them.In developed areas,few people think about the source of the medicines they buy in a store.Yet many widely-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 urgent concern.This is because the earth's supply of natural medicines may be dropping rapidly.
选项
The passage indicates that ancient treatments for injury and disease were_____.A: much more successful than modern onesB: successful enough for humans to surviveC: successful in all casesD: of little help to humans
答案
B
解析
第一段“…successful enough to keep humans from dying out completely”(有效地使人类免于完全消亡)与选项B“ successful enough for humans to survive”(有效地使人类生存下来)意思一样。短文中并没有对选项A的内容做比较,实际上也不可能笼统地做这种比较。选项C和D凭常识也能做出判断,绝对肯定和绝对否定都是错误的。 第三段第一句和第二句对选项A中的“all over the world”作了否定,而其他三个选项的内容在短文中都直接或间接谈到:选项B的内容在第二段最后一句和第三段第一句、第二句都间接提到,我们自然会想到,大医院有现代化的医疗设备,有经过高等教育的医生,有现代化的药品,看病的价格当然昂贵;第三段最后一句的内容与选项C的文字完全相同;第一段第一句的内容与选项D的内容也相同。 第四段最后一句提供了本问题的答案,两处除了句子结构不同以外,文字完全相同。其他三个选项的内容短文都没有提及,根据常识判断也可以知道它们不是正确答案。 第五段第一句直接提供了本题的答案。 短文最后一句直接提供了本问题的答案,其他三个选项均与此完全相反。
