The World's Best-Selling Medicine
Since ancient times,people all over the world have used willow to stop pain. The willow tree contains salicylic acid（水杨酸）.This stops pain, but there is one problem. Salicylic acid also hurts the stomach. In 1853,a French scientist made a mixture from willow that did not hurt the stomach.
However,his mixture was difficult to make,and he did not try to produce or sell it.
In 1897,in Germany,Felix Hoffmann also made a mixture with salicylic acid. He tried it himself first and then gave it to his father because his father was old and in a lot of pain.
His father's pain went away,and the mixture did not hurt his stomach.
Hoffmann worked for Bayer,a German company. He showed his new drug to his manager,who tested the drug and found that it worked well.Bayer decided to make the drug.
They called it aspirin and put the Bayer name on every pill.
Aspirin was an immediate success. Almost everyone has pain of some kind,so aspirin answered a true need. Aspirin was cheap,easy to take,and effective. It also lowered fevers.
Aspirin was a wonder drug.
At first,Bayer sold the drug through doctors,who then sold it to their patients. In 1915,the company started to sell aspirin in drugstores.In the United States,Bayer had a patent（专利权）on the drug. Other companies could make similar products and sell them in other countries,but only bayer could make and sell aspirin in the United States.In time,Bayer could no longer own the name aspirin in the United States. Other companies could make it there,too.However,Bayer aspirin was the most well known,and for many years,it was the market leader.
By the 1950s,new painkillers were on the market. Aspirin was no longer the only way to treat pain and reduce fever. Bayer and other companies looked for other drugs to make.However,in the l970s they got a surprise. Doctors noticed that patients who were taking aspirin had fewer heart attacks than other people. A British researcher named John Vane found the reason aspirin helped to prevent heart attacks.In 1982,he won the Nobel prize for his research. Doctors started to tell some of their patients to take aspirin every day to prevent heart attacks.It has made life better for the many people who take it. It has also made a lot of mon-ey for companies like Bayer that produce and sell it!

Why was Felix Hoffmann looking for a painkiller?
A: His company told him to do that.
B: His father was in pain.
C: He wanted to make a lot of money.
D: He suffered from headache.

参考答案

参考解析
解析：题干意为“为什么法国科学家没有继续制造止痛药？”因为它很难制作。短文第一段最后两句提到“1853年，法国的一位科学家以柳树为原料制成了一种混合物，这种混合物不伤胃。然而这种混合物很难制造，他没有试着生产和销售”，故选D。
题干意为“为什么霍夫曼一直在寻找一种止痛药？”他父亲处于痛苦之中。短文第二段前两句提到“1897年，德国的霍夫曼也用水杨酸制成了一种混合物。他先在自己身上尝试，然后给自己的父亲用，因为他父亲年纪大了并且处在痛苦中”，故选B。
题干意为“拜耳开始生产阿司匹林因为它能有效止痛。”短文第三段前三句提到“霍夫曼在德国的拜耳公司工作，他将自己的新药拿给经理，经理测试了新药，发现它非常有效，于是拜耳决定生产这种药”，故选C。
题干意为“拜耳的阿司匹林是最早在美国销售的阿司匹林。”短文倒数第二段第三句提到，“在美国拜耳有药物的专利权，只有拜耳可以在美国制造和销售阿司匹林，最后，拜耳在美国不但单独拥有阿司匹林，其他公司也可以在那里制造。但是，拜耳的阿司匹林 一直是最出名的，多年来一直是市场领导者”，故选B。
题干意为“市场上出现新的止痛药之后，阿司匹林结局如何？”它的新用途被发现。短文最后一段第五句提到“医生们注意到，服用阿司匹林的病人比其他人得心脏病的几率要小”，故选C。

考题 The human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us aajust to the outside world. Without our nerves and our brain, which is a system of nerves, we couldn’t know what’s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir (苦行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, “This will hurts a little,” it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensafion, and sensations are the stuff of life. [共5题]1.The human body has developed a system of nerves that enables us to ________.A.stay relaxedB.avoid painC.stand tortureD.feel pain2.What does the writer mean by saying “we pay for our sensitivity” in Para.1?A.We have to take care of our sense of pain.B.We suffer from our sense of feeling.C.We should try hard to resist pain.D.We are hurt when we feel pain.3.When the author mentions the Indian fakir, he shows that ________.A.fakirs possess magic powerB.Indians are not afraid of painC.people can learn to cope with painD.some people are born without a sense of pain4.What is essential for people to stand pain according to the writer?A.Their relaxation.B.Their interest.C.Their nerves.D.Their attitude.5.The author believes that ________.A.feeling pain is part of our lifeB.pain should be avoided at all costsC.feeling pain can be an interesting thingD.magic power is essential for reducing pain

考题 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. What do the majority of the people in the world use for health care?A:Strange and wonderful equipment.B:Factory-produced chemicals.C:Modern medicines.D:Plants.

考题 共用题干 New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.

考题 共用题干 第二篇The World ' s Best-Selling MedicineSince ancient times,people all over the world have used willow to stop pain.The willow tree contains salicylic acid（水杨酸）.This stops pain,but there is one problem. Salicylic acid also hurts the stomach. In1853,a French scientist made a mixture from willow that did not hurt the stomach.However,his mixture was difficult to make,and he did not try to produce or sell it.In 1897,in Germany,Felix Hoffmann also made a mixture with salicylic acid.He tried it himself first and then gave it to his father because his father was old and in a lot of pain.His father's pain went away, and the mixture did not hurt his stomach.Hoffmann worked for Bayer,a German company.He showed his new drug to his manager,who tested the drug and found that it worked well.Bayer decided to make the drug. They called it aspirin and put the Bayer name on every pill.Aspirin was an immediate success.Almost everyone has pain of some kind,so aspirin answered a true need.Aspirin was cheap,easy to take,and effective.It also lowered fevers.Aspirin was a wonder drug.At first,Bayer sold the drug through doctors,who then sold it to their patients.In 1915,the company started to sell aspirin in drugstores. In the United States , Bayer had a patent（专利权）on the drug. Other companies could make similar products and sell them in other countries,but only Bayer could make and sell aspirin in the United States.In time,Bayer could no longer own the name aspirin in the United States. Other companies could make it there,too.However,Bayer aspirin was the most well known,and for many years,it was the market leader.By the 1950s,new painkillers were on the market.Aspirin was no.longer the only way to treat pain and reduce fever. Bayer and other companies looked for other drugs to make.However,in the l970s they got a surprise.Doctors noticed that patients who were taking aspirin had fewer heart attacks than other people.A British researcher named John Vane found the reason aspirin helped to prevent heart attacks.In 1982,he won the Nobel Prize for his research.Doctors started to tell some of their patients to take aspirin every day to pre- vent heart attacks.It has made life better for the many people who take it.It has also made a lot of money for companies like Bayer that produce and sell it! Bayer aspirin was________.A:the only drug with the name"aspirin"B:the first aspirin sold in the United StatesC:not sold in drugstores in 1915D:not easy to find in drugstores

考题 共用题干 New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with. Coffee originally came from_______.A:.BrazilB: ColombiaC:EthiopiaD: Arabia

考题 问答题Directions:In this section, there is one passage followed by a summary. Read the passage carefully and complete the summary below by choosing a maximum of three words from the passage to fill in the spaces 76-80. Remember to write the answers on the Answer Sheet.　　Questions 1-5 are based on the following passage.　　Headaches are a big problem. But they are not just a problem for the person suffering from the headache. They are a problem for society as well. Each year, millions of people suffer from severe headaches that keep them from doing their jobs. In fact, according to one estimate, headaches cost individuals and businesses more than $50 billion each year! This is one of the reasons research into headaches has become a worldwide effort.　　Although he did not know much about how headaches work, Hippocrates was the first doctor to find a way to treat them. Before 400 B.C., Hippocrates discovered that the bark from willow trees was useful in treating pain. He made a white powder from the tree’s bark and gave it to his patients.　　Hippocrates did not know it, but he was actually prescribing a natural chemical in willow bark called salicin. When a person eats salicin, the chemical is changed inside her or his body into salicylic acid. It turns out that salicylic acid is good for stopping pain, including headache, but it is bad for a person’s stomach. In the 1800s, a chemist in Germany changed the acid’s form a little to make it easier for people to take. This new form of the chemical was called acetylsalicylic acid, commonly known as aspirin today.　　Aspirin was used throughout most of the 1900s to treat headaches, but doctors had little idea about what really caused headaches. When doctors know the cause of a disease, they can find better ways to treat it. Therefore, as medical technology developed, doctors began to use the technology to learn more about the human brain and about headaches.　　Currently, doctors classify headaches into two general types: primary and secondary. A primary headache is a condition suffered as only the headache itself. On the other hand, a secondary headache is one caused by another condition. For example, someone who catches the flu may suffer from headaches along with other symptoms of the illness. Flu headaches are thus secondary headaches.　　For primary headaches, doctors have determined three possible causes. One kind of primary headache is caused by stress. Doctors usually call these tension headaches. Such headaches are characteristically felt on both sides of the head as a dull, steady pain.Another kind of primary headache is the migraine headache. Doctors believe these headaches are caused by reduced flow of blood to certain parts of the brain. A migraine sufferer usually feels intense pain on one side of the head. The sufferer also becomes sensitive to light and noise. If the migraine is severe, the sufferer may vomit repeatedly.　　The third kind of primary headache is known as the cluster headache. Cluster headaches typically occur around the same time each day for weeks or months at a time. The person suffering from this kind of headache usually feels pain on one side of her or his head, and the pain is centered around one of the person’s eyes. Doctors do not know much at present about cluster headaches, but they seem more common among men and could be related to alcohol or other things that affect a person’s blood flow.　　Using computers and more advanced medical equipment, doctors continue to learn more about what happens in the brain before and during headaches. Especially in the case of migraines, some doctors believe they have found the part of the brain that sets off the reaction for severe attacks. With this new insight into brain processes, doctors hope new ways will be discovered for stopping disabling headaches before they begin.　　Summary:　　Doctors knew a long time ago that the 　1　from the willow trees could help people who felt pain. Hippocrates was the first doctor to change organic material into a powder and give it to his patients. But it was not until the 1800s that this natural drug was altered and became known as 　2　.　　With the help of technology, doctors have now gained detailed insight into how the brain works and what happens when a person suffers from a headache. Through this research, headaches have been 　3　primary and secondary headaches. There are three types of primary headaches: tension, migraine, and cluster headaches. Although not much is known about cluster headaches, doctors have been able to determine some of the things that 　4　During a migraine attack, the sufferer may become 　5　and noise.
