Natural
Medicine{{/B}} Since 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 hospitals. 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 because 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 modem 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.
单选题
The passage indicates that ancient treatments for injury and disease were______.
【正确答案】
C
【答案解析】[解析] 借助常识和备选项巾的用词判断C是答案。如果借助原文：利用“ancient treatments”作为答案线索词，这样在第一段中找到直接答案相关句：Since 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．该句说“古代对疾病的治疗很成功，是以防止人类的安全灭亡”，显然该句内容与c“古代对疾病的治疗很成功，能使人类生存下去”的内容一致。
die out：灭绝，逐渐消失，渐渐止息
keep．．．from．．．阻止，隐瞒，抑制
单选题
Which of the following statements is NOT true?
【正确答案】
B
【答案解析】[解析] 借助常识判断B(B说的太绝对)是答案。如果借助原文：分别利用各备选项中的核心词/特征词作为答案线索(A：modem hospitals，Many；B：Modem medicines，all over the world；C： Traditional medicines；D：earliest days)，找到答案相关句，可以首先对最可能成为答案选项的B进行判断。 Many parts of the world(与B中的all over the world在结构和内容上相关)still do not have university-educated doctors．该句说“实际上许多地方仍然缺乏接受过大学教育的医生”，根据这个内容不难推断出：医生都缺乏，现代的药品肯定也应该在这些地方缺乏，因此判断B是答案。
