Natural Medicines
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 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.

第1题：
(41~45) Researchers have found that drugs used to treat human seizures can delay aging in worms by as much as 50 percent. The roundworms used for the study are similar to humans in their molecular makeup, raising the
possibility that the drugs could also extend the life span of humans。
第41题：“By finding a class of drugs that delays aging we have found a relationship between the function of the nervous system and aging that was not well understood, ” said Kerry Komfeld, a geneticist at the Washington University School of Medicine in St. Louis, Missouri. The findings are detailed this week in the journal Science。 The discovery came out of the thesis work by one of Komfeld’s graduate students, Kimberley Evason. About four years ago, Evason began exposing groups of the roundworm Caenorhabditis elegans to commercially available drugs to see if the drugs would delay aging or promote longevity。
A. But Komfeld said scientists will not know about the applicability of the drugs in humans until a similar study is done on humans. “What’s very encouraging is that these drugs were developed to treat humans, and they are well understood, because they’ve been used for a long time, ” he said。
B. Later the scientists discovered that two related anticonvulsant drugs also lengthened the lives of the worms-in the case of one drug, by almost 50 percent. “This was a big surprise to use, Komfeld said. ”“We didn’t think anticonvulsant drugs had any particular relationship to aging. That connection was completely unexpected. ”
C. Roundworms are a poor subject for experiments, because they are not like humans, even though their molecules are similar. For example, they have no bones, nor do they show emotions, making it difficult to know how exactly human subjects would react to these drugs in large quantities. However, using the worms allows experiments to be conducted quickly, because they do not live for long。
D. “Somehow the neural activity seems to regulate the aging of all of the body the skin, musculature, and reproductive tract, ” Kornfeld said. “Somehow the nervous system coordinates the progress of all these tissues, evidently, though the life stages. But we don’t know how it does that. ”
E. The discovery may also shed light on the little-understood aging process. Since the drugs act on the neuromuscular systems of both humans and worms, the findings hint at a link between neural activity and aging。
F. Unlike vertebrates, the worms are ideal subjects for the study of aging because of their short life spans, which last only a couple of weeks in a laboratory. The worm is well known in genetics, and the worm’s genome has been sequenced。
G. Use of this drug has been permitted by law since 1998 and wider use is now expected as a result of the studies. “We can clearly link this drug with human aging, but we still need to find proof, says Kornfeld optimistically. ”
正确答案：E空前文字提出了文章的主题，也就是概括性地介绍了文章的内容：“一项研究表明治疗人类突发性疾病的药物能延缓虫子的衰老，由于人类的分子结构与虫子相似，所以有可能这种药物也能延缓人类的衰老”。只有选项E继续概括性地介绍了文章的内容：“这项研究同样也表明神经肌肉活动与衰老有关系”。 -

第二篇
Ancient Egypt Brought Down by Famine
Even ancient Egypt's mighty pyramid（金字塔）builders were powerless in the face of
the famine（饥荒）that helped bring down their civilization around 2180 BC.Now evidence
collected from mud deposited by the River Nile suggests that a shift in climate thousands of
kilometers to the south was ultimately to blame一and the same or worse could happen today.
The ancient Egyptians depended on the Nile's annual floods to irrigate their crops.But
any change in climate that pushed the African monsoons（季风）southwards out of Ethiopia
would have reduced these floods.
Declining rains in the Ethiopian highlands would have meant fewer plants to stabilize the
soil.When rain did fall it would have washed large amounts of soil into the Blue Nile and
into Egypt,along with sediment（沉积）from the White Nile.
Blue Nile mud has a different isotope（同位素）signature from that of the White Nile.
So by analyzing isotope differences in mud deposited in the Nile Delta,Michael Krom of
Leeds University worked out what proportion of sediment came from each branch of the
river.
Krom reasons that during periods of drought,the amount of Blue Nile mud in the river
would be relatively high.He found that one of these periods,from 4500 to 4200 years ago,
immediately came before the fall of the Egypt's Old Kingdom.
The weakened waters would have been disaster for the Egyptians."Changes that affect
food supply don't have to be very large to have a ripple（波浪）effect in societies."says
Bill Ryan of the Lamont Doherty Earth Observatory in New York.
Similar events today could be even more devastating,says team member Daniel
Stanley,a scientist from the Smithsonian Institution in Washington D.C,"Anything humans
do to shift the climate belts would have an even worse effect along the Nile system today
because the populations have increased dramatically."Why does the author mention"Egypt's mighty pyramid builders"?
A:Because they once worked miracles.
B:Because they were well-built.
C:Because they were actually very weak.
D:Because even they were unable to rescue their civilization.答案：D解析： -

Cats are creatures of habit.They like to go to sleep about the same time every day and for a certain length of time.They seem to have a natural clock inside them that tells them when to sleep.
Cats increase their regular sleep with occasional cat naps（打盹）.Some experts feel that humans could also benefit from this habit.Cat naps help to build up energy in the body.They are also a good way to get rid of trouble!Since cats have the same moods（情绪）as humans,some experts behave that people can improve their moods.People might become happier.
A number of famous people have copied cats by taking cat naps during the day.The naps would usually last from 15 to 30 minutes.
Winston Churchill took cat naps.So did Presidents Harry Truman,John F.Kennedy and Lyndon B.Johnson.These famous men were known for their energy.They were also able to work long hours,often into the night.Napping was their secret.
Perhaps more people learn from cats and take naps to feel better and live longer!
Which of the following statements is NOT true?A.People should take their naps secretly.
B.Cats have the same moods as people.
C.Some famous people take cat naps.
D.Some people have full energy after they take cat naps.答案：A解析：考情点拨:推理判断题。应试指导:文章讲述人们学习猫打盹的方式有益处，而不是要人们偷偷地打盹。 -
第12题：
问答题Animal rights are a controversial topic right now. Actually, the debate is focused mainly on animal testing. The following are opinions from both sides. Read the excerpts carefully and write your response in about 300 words, in which you should: 1. summarize briefly the opinions from both sides, and then 2. give your comment. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. Animals are used for research in a variety of settings, including tests to determine the safety of drugs, cosmetics and other substances. Whether or not humans should use animals for testing purposes, however, is a controversial subject. Dr. Bob Miller, a medical researcher from Michigan State University, states that one of the primary advantages of animal testing is that it allows researchers to develop new medications and treatments, advancing the field of medicine and enhancing the health of society. For instance, many drugs used to treat or prevent cancer, HIV, diabetes, infections and other medical maladies have resulted from tests performed on animals. Moreover, animal testing enables scientists and researchers to test the safety of medications and other substances with which humans have regular contact. Drugs, for instance, may pose significant risks to humans, so testing them on animals fast gives researchers a chance to determine drugs’ safety before human trials are performed. While scientists are cognizant of the differences between humans and animals, the similarities are considered significant enough to produce relevant, useful data that they can then apply to humans. Thus, animal testing reduces harm to humans and saves lives. However, Prof. Abhay Shina, a leading critic of animal testing, points out that the major disadvantage to animal testing is that a significant number of animals are harmed or die as a result of experiments and testing. Unfortunately, many of the substances used on animal subjects never receive approval for human use or consumption. Humans receive no direct benefits as a result of the deaths of these animals. He also argues that animals are dissimilar enough from humans to make the results of animal tests unreliable. A related criticism is that testing induces stress in the animals, meaning that the subjects do not react to experimental substances in the same way that they might in more natural circumstances, making the results of experiments less valid. Using animals as research subjects is also expensive, because the animals require food, shelter, care and treatment in addition to the costs of experimental substances. Long-term or multi-phase tests can increase the costs of the practice as well. The actual price paid for the animals is also worth consideration; there are companies that breed and sell animals specifically for testing purposes.正确答案：
【参考范文】
My View on Animal Testing Animal rights has gained more and more attention nowadays. The debate on animal testing is increasingly heated. When asked whether animal testing should be allowed or not, different people have different views. Supporters believe that animal testing help develop new medications and treatments, advancing the field of medicine and enhancing the health of society and reducing risks to humans and saving lives. However, some people criticize animal testing. They argue that animal testing is expensive and harms or kills a significant number of animals, bringing no direct benefits and the results may be not reliable.
From my point of view, a limited amount of animal experimentation is necessary in spite of its shortcomings. First, it indeed contributes to the development of medicine and health. Many medical treatments and procedures have been developed from experiments on animals. Since animals share many features with humans, scientists use animals to test the safety and effectiveness of newly developed drugs before pilot testing on small groups of patients. Medical teams also practice new operating techniques such as transplants on animals. Without animal testing, many procedures or new drugs would be extremely unsafe. Second, we simply do not have alternative methods of testing. Computer models are not advanced enough and tests on plants are much less applicable to humans than tests on animals such as monkeys. Until we have a better system, we can only use animal testing.
In conclusion, I am convinced that animal testing is necessary, and that it will continue to benefit humans in new and wonderful ways. But we need to make sure that millions of animals who are used for testing new products have the minimum of suffering. Although some animal testing may be unavoidable at present, treating our fellow creatures as mercifully as possible will demonstrate our humanity.解析：

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 hospi-

might seem mysterious , even magical（有魔力的）.Traditional medicines are neither mysterious nor magical,
however.

第23题：
问答题Practice 4 Charles Darwin didn’t want to murder God, as he once put it. But he did. He didn’t want to defy his fellow Cantabrigians, his gentlemanly Victorian society, his devout wife. But he did. He waited 20 years to publish his theory of natural selection, but—fittingly, after another scientist threatened to be first—he did. Before Darwin, most people accepted some version of biblical creation. Humans were seen as the apotheosis of godly architecture. Humans could thus be an accident of natural selection, not a direct product of God. Worries about how much his theory would shake society exacerbated the strange illnesses he suffered. It’s also worth noting that Darwin’s life wasn’t Darwinian: he achieved his wealth through inheritance, not competition, and some might say his sickly children suffered because they were inbred. Darwin’s theories still provoke opposition. One hundred and forty years after The Origin of Species, backers of creationism have made a comeback in states like Kansas, pushing evolution out of the schoolroom. Yet Darwinism remains one of the most successful scientific theories ever promulgated. There is hardly an element of humanity—not capitalism, not gender relations, certainly not biology—that can be fully understood without its help.正确答案： 【参考译文】
查尔斯·达尔文并不想杀死上帝,他也曾经这样说过。但是他催毁了人们对上帝的信仰。他并不想挑衅剑桥的校友,蔑视温文尔雅的维多利亚社会,违抗虔诚的妻子。但是事与愿违。他为把自然选择的理论公之于众等待了20年,而在另一名科学家可能抢先的情况下他选择了适当的时机——论文最终发表了。
达尔文以前的人一般都相信圣经记载,即人是由上帝创造出来的。人类被神化了,被认为是上帝创造的杰作。但是人类可能只是自然选择中的偶然产物,而不是上帝直接创造的成果。由于担忧这个理论会极大地冲击社会,达尔文的怪病病情加剧。值得一提的是达尔文的一生并不符合他的理论:他的财富并非通过竞争,而是通过继承得来,据说他的孩子多病是由于父母近亲结合的缘故。
今天达尔文的理论仍然有反对的呼声。《物种起源》出版140年后,上帝造人论的支持者在美国堪萨斯等州卷土重来,要求把进化论驱出课堂。然而达尔文的理论仍然是历史上最为成功的科学理论之一。没有进化论,人类的许多问题几乎无法破解,资本主义、性别关系、当然还有生物学等都无法得到完全的认识。 解析： 暂无解析
