A New Way to Help Predict Earthquakes

Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake hits.
Currently, the most modem systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, the one that hit southwestern China in May wasnot identified early enough for people to flee the area. That earthquake killed sixty-nine thousand people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface. Their report was published this month in Nature magazine.
Fenglin Niu is a seismologist with Rice University in Houston, Texas. He and his team performed experiments along California’s San Andreas Fault, an area famous for its many earthquakes.
The team pl
A. It predicts only a short time before event.
B. It cannot tell exact location.
C. It predicts only earthquakes that happened daytime.
D. It predicts only low rate earthquakes.

[单项选择]A scientist who wants to predict the way in which consumers (消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist were asked which of three groups borrow most--people with rising incomes, stable incomes, or decreasing incomes--he would probably answer, those with decreasing incomes. Actually in the years 1947--1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions (假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true.
The expectations of price increases may not stimulate
A. rely on traditional assumptions about earning and spending
B. try to encourage or discourage consumers to spend money
C. carry out investigations on consumer behavior and get data on consumers incomes and money spending motives
D. do researches in consumer psychology in a laboratory
