The past three decades have seen great progress in our kno wledge of dealing with travel dangers．But our attention is ea sily drawn to the new，the fascinating and the challenging，and there has not been much effort to solve the old problem a nd change the way people behave in the sun．
We understand the harmful effects of strong sunlight．As with cigarettes and lung cancer，
there's no need for more research to tell us what we should d o．Nor is much research being carried out．Of the hundreds of papers presented at an international conference on travel ill nesses，there was only a single paper on the sun．
Last month，a fivemonthold baby almost died from sunburn—suffering burns to 40 percent of its skin surface while sleeping on the beach．
Sunburn is only one of the problems caused by strong sunligh t and research results are shocking．In men，
the death rate for malignant melanoma，
the deadliest form of skin cancer，
has more than doubled in the past 30 years—
from 1．5 per 100，000 population to 3．1 per 100，000，according to Cancer Research UK．It is no coincidence that t he same 30year period has seen a rise in travelling．In older age groups，the death rate is much higher．Meanwhile，the number of new cases of melanoma has grown fivefold．M ore women are being diagnosed with melanoma but more me n are dying from it—
men are less likely to seek treatment in time．Other more tre atable skin cancers are also on the rise，
with an estimated 100，000 cases every year．
The underlying reason comes down to this：
most paleskinned people have a strong belief，
deeply rooted in our culture，
that they look better with browner skin．They will risk cancer and pain to support their goal，
and medical education seems to make little difference．
【语篇解读】很多人都知道太阳光线可能造成伤害，但并没有改变行为方式来减少这一伤害。

The US government has recently helped people learn more a bout the dangers of earthquakes by publishing a map．This map shows the chances of an earthquake in each part of the country．The areas of the map where earthquakes are most li kely to occur are called earthquake belts．The government is spending a great deal of money and is working hard to help to discover the answers to these two questions：
Can we predict earthquakes?
Can we control earthquakes?
To answer the first question，
scientists are looking very closely at the most active fault (断层) systems in the country，
such as the San Andreas fault in California．A fault is a break between two sections of the earth's surface．These breaks b etween sections are the places where earthquakes occur．Sc ientists look at the faults for changes which might show that a n earthquake was about to occur．But it will probably be man y years before we can predict earthquakes correctly．And the control of earthquakes is even farther away．
However，
there have been some interesting developments in the field of controlling earthquakes．The most interesting development concerns the Rocky Mountain Arsenal earthquakes．Here water was put into a layer of rocks 4，
000 metres below the surface of the ground．Shortly after thi s injection of water，
there was a small number of earthquakes．Scientists have de cided that the water which was injected into the rocks worked like oil on each other．
When the water “oiled” the fault，
the fault became slippery and the energy of an earthquake wa s given out．Scientists are still experimenting at the site of th ese earthquakes．They have realized that there is a connecti on between the injection of the water and the earthquake acti vity．They have suggested that it might be possible to use thi s knowledge to prevent very big，dangerous earthquakes，that is，
scientists could inject some kind of fluid like water into faults a nd change one big earthquake into a number of small，harmless earthquakes．
【语篇解读】为了提高人们对地震的防范意识，美国政府加大了在防震、预测方面的投入，他们甚至在努力采取措施控制地震的发生。

5．Earthquakes belts are ．
A．maps that show where earthquakes are likely to occur B．zones with a high probability of earthquakes
C．breaks between two sections of the earth's surface D．the two layers of earth along a fault
B [细节理解题。

根据第一段的第三句可知，地震多发地带被称为earthquake belts。

6．The San Andreas fault is ．
A．an active fault system
B．a place where earthquakes have been predicted correctly C．a place where earthquakes have been controlled
D．at the foot of the
A [细节理解题。

根据第四段可知，该地区为地震比较活跃的地区。

7．What did scientists learn about earthquakes at the Rocky Mountain Arsenal?
A．They occur at about 4，000 metres below ground level．B．The injection of water into earthquake faults prevents eart hquakes from occurring．
C．They are usually caused by the oil in the faults．D．Harmful earthquakes could be prevented by causing harm less earthquakes．
D [细节理解题。

根据最后一段尾句可知。

8．What can be said about the experiments at the Rocky Mo untain Arsenal?
A．They have no practical value in earthquake prevention．B．They may have practical value in earthquake prevention．C．They are certain to have practical value in earthquake pre vention．
D．Nothing is told about their practical value in earthquake pr
evention．
B [推理判断题。

根据科学家的试验，通过向断裂带注水可以引发小地震，从而使地震的能量得到释放，因此也就降低了大地震爆发的可能。
