Drug Reactions--a Major Cause of Death
Adverse drug reactions may cause the deaths of over 100,000 US hospital patients each year, making them a leading cause of death nationwide, according to a report in the Journal of the American Medical Association.
"The incidence of serious and fatal adverse drug reactions (ADRs) in US hospitals was found to be extremely high. " say researchers at the University of Toronto in Ontario, Canada.
They carried on an analysis of 39 ADR-related studies at US hospitals over the past 30 years and defined an ADR as "any harmful, unintended, and undesired effect of a drug which occurs at doses used in humans for prevention, diagnosis, or therapy. "
An average 6.7% of all hospitalized patients experience an ADR every year, according to the researchers. They estimate that " In 1994, overall 2,216,000 hospitalized patients had serious ADRs, and 106,000 had fatal ADRs. " This means that ADRs may rank as the fourth single largest cause of death in America.
And these incidence figures are probably conservative, the researchers add, since their ADR, definition did not include outcomes linked to problems in drug administration, overdoses, drug abuse, and therapeutic failures.
The control of ADRs also means spending more money. One US study estimated the overall cost of treating ADRs at up to $ 4 billion per year.
Dr. David Bates of Brigham and Women's Hospital in Boston, Massachusetts, believes that healthcare workers need to pay more attention to the problem, especially since many ADRs are easily preventable. "When a patient develops an allergy or sensitivity, it is often not recorded, " Bates notes, "and patients receive drugs to which they have known allergies or sensitivities with disturbing frequency. " He believes computerized surveillance systems--still works-in-progress at many of the nation's hospitals--should help cut down the frequency of these types of errors.
Researchers at the University of Toronto believe that ______.
A．ADRs have caused medical problems, though they seldom lead to death
B．ADRs have very often caused patients to die in Canada
C．ADRs have caused many deaths in America over the past 30 years
D．it is easy to prevent ADRs from happening

2. The Untied Nations Children's Fund, UNICEF, list four ways to improve children's health. The first way is to use a mixture of sugar, salt and water to treat diarrhea (腹泻). The second way is to use vaccines(疫苗)to protect children against common diseases. The third way is to feed babies mother's milk. And the fourth way is to measure carefully children's growth rates.
3. Diarrhea is the major cause of death among children in developing countries. Diarrhea results when the body tries to clear itself of harmful bacteria. The body does this by forcing fluids out, sometimes uncontrollably, from the bowels(肠). If too much water, sugar and salt are lost in this way, the kidneys(肾)and heart cannot work normally, The child may die.
4. UNICEF's diarrhea treatment is called Oral Rehydration Therapy. It uses a simple mixture of sugar and salt in water. The mixture does not stop diarrhea. But if used as often as needed, it keeps fluid levels normal until the body has fought off the harmful bacteria.
A. Four ways to improve children's health
B. The major cause of death--diarrhea
C. How to cure diarrhea
D. The situation of young children in the world
E. UNICEF's diarrhea treatment
F. The cost of the diarrhea treatment

Earthquake
1 Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which are initiated by the quake.
2 There are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest scale recorded to date is 8.9. Major damage generally occurs from quakes ranging upwards from 6.0.
3 The actual cause of the quake itself is the breaking of rocks at or below the earth's surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth's crust and continental drift.
4 In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will enable them to indicate the exact time, location and size of an earthquake.
5 Certain phenomena have been observed which are believed to be the signs of imminent earthquakes. These include strange behaviours of some animals, the changes in the content of mineral water, etc. The magnetic properties of rocks may also display special pattern before major earthquakes happen.
A Earthquake's Forecast
B Historical Records of Earthquakes
C Intensities of Earthquakes
D Cause of Earthquakes
E Indications of Earthquakes
F Damaging Earthquakes
Paragraph 2 ______ .

A Great Quake Coming？
Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area-and they can be devastating．In 1906，for example，a major quake destroyed about 28,000 buildings and killed hundreds，perhaps thousands of people．Residents now wonder when the next“Big One”will strike．It's bound to happen someday．At least seven active fault(断层)lines run through the San Francisco area． Faults are places where pieces of Earth's crust(地壳)slide past each other．When these pieces slip，the ground shakes．
To prepare for that day，scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens．
One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time．During small earthquakes，faults rupture(断裂)at about 2.7 kilometers per second．During bigger quakes，however，ruptures can happen at rates faster than 3.5 kilometers per second．
At such high speeds，massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself．Lucky for San Francisco，these pressure pulses(脉冲)traveled away from the city during the 1906 event．As bad as the damage was，it could have been far worse．
Looking ahead，scientists are trying to predict when the next major quake will occur．Records show that earthquakes were common before 1906．Since then，the area has been relatively quiet．Patterns in the data，however，suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent．
New buildings in San Francisco are quite safe in case of future quakes．Still，more than 84 percent of the city's buildings are old and weak．Analyses suggest that another massive earthquake would cause extensive damage．
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while．According to the new research，however，it's not a matter of“if”the Big One will hit．It's just a matter of when．
The San Francisco area is located above several active fault lines．
A．Right
B．Wrong
C．Not mentioned
