You should make the correct choice. 21 In medicine, blood type is the classification of red blood cells by the presence of specific substances on their surfac
11、e. In the early part of the 20th century, physicians discovered that blood transfusions often failed because the blood type of the recipient was not compatible with that of the donor. In 1901 the Austrian doctor Karl Landsteiner classified blood types and discovered that the hereditary blood factor
12、is of great importance in blood transfusions because it creates reactions that can threaten the life of newborn infants. The four blood types are known as A, B, AB, and O. Blood type A contains red blood cells that have a substance A on their surface. This type of blood also contains an antibody dir
13、ected against substance B, which can be found on the red cells of persons with blood type B. Type B blood contains the opposite things. Blood type AB contains neither antibody, but red cells in this type of blood contain both A and B substances. In type O blood, neither substance is present on the r
14、ed cells, but the individual is capable of forming antibodies directed against red cells containing substance A or B, If blood type A is transfused into a person with B type blood, anti-A antibodies in the recipient will destroy the transfused A red cells. Because O type blood has neither substance
15、on its red cells, it can be given successfully to almost any person. Persons with blood type AB have no antibodies and can receive any of the four types of blood; thus blood types O and AB are called universal donors and universal recipients, respectively. Other hereditary(遗传的 ) blood-group systems
16、have subsequently been discovered, for example, the Rh blood factor. And nowadays more than twenty additional blood types have been discovered. Their importance is obvious. 21 In the early part of the 20th century, physicians discovered that blood transfusions often failed because _. （ A） the blood
17、type of the donor was not compatible with that of the recipient （ B） the blood type of the recipient was not suitable for that of the donor （ C） blood type A contains red blood cells that have a substance A on their surface （ D） blood cells are necessary for blood transfusion 22 Which of the followi

19、s in this type of blood neither contain both A and B substances. 23 If a patient whose blood type is O needs blood transfusion, who can be the donor? （ A） Blood typea. （ B） Blood typeb. （ C） Blood type AB. （ D） Blood type O. 24 A babys blood type is decided by _. （ A） his father or his mother （ B） h

21、nimals and are among the longest-lived, with life spans of 60 years or more. Healthy, full-grown elephants have no natural enemies other than humans. Elephants once lived on every continent except Australia and Antarctica, but elephants today are restricted to Africa and parts of Southeast Asia. The
22、y occupy a wide range of environments in Africa and Southeast Asia: grasslands, marshes, forests, deserts, and mountains. They need great quantities of food to support their massive size. They also need a lot of drinking water and so are restricted to areas with adequate water. Throughout history, p
23、eople have prized elephants for their great size and strength. On the battlefield, elephants have defeated the enemies. Elephants also have been trained to carry heavy supplies through the forests where they once lived. Elephants have long been honored, and in Thailand, India, and other Southeast As
24、ian countries, beautifully decorated elephants still play a significant role in traditional religious ceremonies. Over the past 40 million years, more than 600 species of elephants have lived on the earth. Today only two species are alive: the African elephant and the Asian elephant. Climate changes
25、 caused the extinction of many elephant species, but human influence has also taken its toll. At the turn of the 20th century, elephants numbered from 5 million to 10 million, but widespread hunting and city expanding reduced their numbers to an estimated 640,000 by the end of the century. At presen
26、t, efforts to save elephants may be inadequate, and biologists are unsure if elephants as a species will survive. 26 From the first paragraph, we can deduce that _. （ A） highly intelligent and strong, elephants are the largest land animals （ B） elephants are among the longest-lived, with life spans
27、of 60 years or less （ C） healthy, full-grown elephants have natural enemies rather than humans （ D） human beings bring great harm to the elephants 27 Which of the following is NOT concerned with the elephants? （ A） Elephants today are restricted to Africa and parts of Southeast Asia. （ B） They occup
28、y a wide range of environments: marshes, forests, grasslands, mountains, and deserts. （ C） They also need a lot of drinking water and so are restricted to areas with inadequate water. （ D） They need great quantities of food to support their massive size. 28 According to the passage, elephant can do
29、many things EXCEPT _. （ A） elephants can help people to drive the invaders out of the country （ B） elephants also have been trained to carry heavy goods through the forests （ C） throughout history, people have prized elephants for their great size and strength （ D） beautifully decorated elephants st
30、ill play a significant role in traditional religious ceremonies 29 On the forth paragraph, the word “extinction“ in the sentence “Climate changes caused the extinction of many elephant species, but human influence has also taken its toll.“ means _. （ A） evolution （ B） distinction （ C） production （ D
31、） depopulation 30 The best title of the passage is _. （ A） An Introduction of Elephants （ B） The Living Characteristics of Elephants （ C） Elephants Environments （ D） Elephants Population 31 In its most extreme form, poverty is a lack of basic human needs, such as adequate and nutritious food, clothi
32、ng, housing, clean water, and health services. Extreme poverty can cause terrible suffering and death, and even poverty can prevent people from realizing many of their desires. The worlds poorest people-many of whom live in developing areas of Africa, Asia, Latin America. and Eastern Europe-struggle
33、 daily for food, shelter, and other necessities. They often suffer from severe malnutrition(营养不良 ), infectious disease outbreaks, famine, and war. In wealthier countries-such as the United States, Canada, Japan, and those in Western Europe-the effects of poverty may include poor nutrition, mental il
34、lness, drug dependence, crime, and high rates of disease. Extreme poverty, which threatens peoples health or lives, is also known as destitution or absolute poverty. Relative poverty is the condition of having fewer resources or less income than others within a society or county, or compared to worl
35、dwide averages. The reasons for poverty are not clear. Some people believe that poverty results from a lack of adequate resources on a global level-resources such as land, food, and building materials-that are necessary for the well-being or survival of the worlds people. Other see poverty as an eff
36、ect of the uneven distribution Of resources around the world on an international or even regional scale. This second line of reasoning helps explain why many people have much more than they need to live in comfort, while many others do not have enough resources to live. 31 What is the best title of
37、the passage? （ A） Extreme Poverty （ B） Relative Poverty （ C） Poverty （ D） Why People are poverty 32 According to the passage which of the following is the best definition of the poverty? （ A） Poverty is the condition of having insufficient resources or income. （ B） Poverty is a lack of basic human n
38、eeds. （ C） Poverty is the condition of having fewer resources or less income than others within a society or country, or compared to worldwide averages. （ D） Poverty is an effect of the uneven distribution of resources around the world on an international or even regional scale. 33 What is the main
39、idea about the first paragraph? （ A） What is the extreme poverty trod its cause and effect? （ B） An introduction of the relative poverty. （ C） An introduction of the extreme poverty. （ D） Why people are poverty? 34 It can be inferred from the passage that _. （ A） the poverty in the developing countr
40、y is different from the developed country （ B） relative poverty is more terrible than extreme poverty （ C） there are many reasons for poverty （ D） many people have much more than they need to live in comfort, while many others do not have enough resources to live 35 In the last paragraph “Others see
41、 poverty as an effect of the uneven distribution of resources around the world on an international or even regional scale.“, the word “uneven“ probably means _. （ A） odd （ B） unequal （ C） different （ D） identical 36 A sick or injured person can obtain medical care in several different places. These
42、include provider practices such as medical offices and clinics, hospitals and nursing homes. There are about 200,000 medical offices, clinics, and other provider practices in the United States. Earlier in the 20th century most physicians were single people working in their own offices or in partners
43、hip with another doctor. Patients visited the office, received an examination or other service, and paid a fee. This traditional fee-for-service medicine has been declining. Many physicians now practice in groups where they share the same offices and equipment with other doctors. Group practices may
44、 combine primary care physicians, several kinds of specialists, laboratories, and equipment for diagnosing disease. Physicians who practice in a group reduce their own expenses and provide patients with a wider range of services. Many doctors are joining with hospitals, insurance companies, and indu
45、strial employers to provide managed care for groups of patients. These plans manage to avoid unnecessary services and reduce costs. Rather than taking a fee from each patient, managed care physicians may receive an annual salary from a fixed sum for each patient. Patients who are too sick for care i
46、n a doctors office go to a hospital. Hospitals offer Patients 24-hour care from a staff of health professionals. They provide services not available elsewhere, such as major surgery, child birth, and intensive care for the critically ill. Hospital care is the most expensive form of health care. Effo
47、rts to control health care costs have emphasized reducing the number of patients admitted to hospitals and their length of stay. During the 1980s and 1990s, these efforts led to the closing of more than 600 hospitals. Patients who need long-term medical care because of advanced age or chronic illnes
48、s may stay in a nursing home. The United States has about 23,000 nursing homes with about 1.3 million patients. 36 Earlier in the 20th century, people often went to the _ to check the illness. （ A） group practices office （ B） physicians office （ C） hospitals （ D） clinics 37 “Physicians who practice
