Predicting the unpredictable


Some years ago, a devastating earthquake struck the Italian town of L’Aquila. More than 300 people lost their lives, over 1,500 people were injured, and many buildings were destroyed. Two years later, seven earthquake experts were involved in a court case: Did they adequately warn the public after the initial tremors began? At the heart of the debate is whether they could have predicted a disaster like this.


Although a lot of scientists are working to improve our ability to predict natural disasters, so far no one has come up with a reliable method to forecast earthquakes or volcanic eruptions, days or weeks beforehand. Most of the research focuses on the areas most likely to experience seismic activity – but even our knowledge about where these areas are, is very limited. One reason for this is that human beings have only been around for a very small part of the Earth’s history. In geological terms, we all arrived on the scene very recently. Records from the past 2,000 years are incomplete, and the biggest earthquakes nearly always happen in areas where there have been no earthquakes in recorded history.


So, is there any hope for improving our ability to predict disasters? A solution may come from an unexpected source. Four years ago, a team of US physicists at Rutgers University in New Jersey were studying why pharmaceutical powders stick together. They observed that the powder stuck together when placed in a spinning cylinder, but then developed cracks and collapsed. Just before the cracks developed, an electric signal, like a small bolt of lightning, was created. The scientists repeated the experiment with a wide range of different materials, and they got similar results every time.


This phenomenon might also exist in nature. Some scientists believe that rocks may become electrically charged under unusual pressure, such as before an earthquake. This electric charge then causes changes in the surrounding air or water, which animals may be able to sense before humans do. For example, while biologists were studying a colony of frogs in a pond near L’Aquila, they noticed that nearly all the animals left the water days before the earthquake. A similar thing happened in China, when snakes were hibernating for the winter in caves, but escaped just before a large earthquake. The same kind of electric charge, like the small bolt of lightning felt in the experiment at Rutgers, may have been responsible.


At the moment, there is no reliable way ............ using such findings to predict earthquakes, and further studies may be necessary to give us a better understanding of the interactions involved, but one day, the technology may be used ............ predict future catastrophes. For example, two science institutions in Russia and Britain are already developing a new micro-satellite, which could detect these electric signals and help rescue people ................ natural disasters in time. Scientists are planning to launch the first of these satellites ............... space. Will these satellites be the solution? Only time will tell. For the time being, the best defense is to be prepared.

Instruction: answer questions 31 to 40 based on the following text. The highlights throughout the text are cited in the questions.


He donated blood and saved the lives of 2.4 million babies


01 Most people get a gold watch when they retire. James Harrison deserves so much more than

02 that. Known as the “Man With the Golden Arm,” Harrison has donated blood nearly every week

03 for 60 years, and after all those donations, the 81-year-old Australian man “retired” Friday.

04 According to the Australian Red Cross Blood Service, he has helped save the lives of more than

05 2.4 million Australian babies because his blood has unique, disease-fighting antibodies.

06 Harrison’s antibodies have been used to develop an injection called Anti-D, which helps

07 fight against rhesus disease. This disease is a condition where a pregnant woman has rhesus-

08 negative blood (RhD negative) and the baby in her womb has rhesus-positive blood (RhD

09 positive), inherited from its father. If the mother has been sensitized to rhesus-positive blood,

10 usually during a previous pregnancy with a rhesus-positive baby, she may produce antibodies

11 that destroy the baby’s “foreign” blood cells. In the worst cases, it can result in brain damage,

12 or death, for the babies.

13 Harrison’s remarkable gift of giving started when he had major chest surgery when he was

14 just 14. Blood donations saved his life, so he pledged to become a blood donor. A few years

15 later, doctors discovered his blood contained the antibody which could be used to create Anti-D

16 injections, so he switched over to making blood plasma donations to help as many people as

17 possible. Doctors aren’t exactly sure why Harrison has this rare blood type, but they think it

18 might be from the transfusions he received when he was 14, after his surgery. He’s one of no

19 more than 50 people in Australia known to have the antibodies, according to the blood service.

20 “In Australia, up until about 1967, there were literally thousands of babies dying each year,

21 doctors didn’t know why, and it was awful.” Jemma Falkenmire, of the Australian Red Cross

22 Blood Service, told CNN. “Australia was one of the first countries to discover a blood donor with

23 this antibody, so it was quite revolutionary at the time.”

24 The blood service estimates Harrison saved more than two million lives, and for that, he is

25 considered a national hero in Australia. He’s won numerous awards for his generosity, including

26 the Medal of the Order of Australia, one of the country’s most prestigious honors. Now that

27 Harrison has given his last blood donation (in Australia you can’t donate blood past the age of

28 81), Falkenmire and others hope people with similar antibodies in their blood will step up and

29 donate.
