16、根据以下内容回答16-35题：
An occasional drink with dinner could reduce the risk of having a stroke(中风)，according to a new study．Researchers found that light to moderate drinkers can lower their risk by about 20 per cent compared with nondrinkers．
The study was the biggest ever to examine the link between alcohol and stroke．It showed that as little as a single glass of wine or beer per week can significantly reduce stroke risk．The study involved more than 22,000 men,but the researchers said the results could also apply to women．
However，the researchers stressed it would be unwise for doctors to advise patients who don’t drink to suddenly start or those who drink small amounts to begin consuming more heavily．The study found no added protection from stroke by drinking more than lightly or moderately．
And researchers warned of possible harms posed by alcohol，such as liver damage，the dangers of driving while drunk and the risk of breast cancer in women．
What’S more，there are other ways to reduce stroke risk，such as quitting smoking or lowering blood pressure．
Numerous studies have shown that modest drinking reduces the risk of heart disease．But until now，the evidence of an effect on strokes has been less convincing．Early studies were criticized because they simply compared drinkers to non-drinkers．This latest study examined varying levels of alcohol intake．It found that between one drink a week and one a day reduces the risk，and the lesser amount was about as good as the higher one．

Earthquakes may rightly be ranked as one of the most destructive forces known to man：since reeords began to be written down，it has been estimated that earthquake-related fatalities(死亡)have numbered in the millions，and that earthquake-related destruction has been be-vond calculation．The greater part of such damage and loss of life has been due to falling down of buildings and the effects of rockslides，floods，fire，disease，gigantic sea waves，and other phenomena(现象)resulting from earthquakes，rather than from the quakes themselves．
The great majority of all earthquakes occur Off two specific areas，along the coasts of the Pacific Ocean and from the East Indies to the Atlas Mountains．But they may，however，happen anywhere at any time．
This element of the unknown has for centuries added greatly to the fear and horror sur-rounding earthquakes，but in recent times there have been indications that earthquake predic-tion may be possible．By analyzing changes in animal behavior，patterns of movements in the earth’S surface．and other unusual phenomena，scientists have shown increasing Success in pre-dicting when and where earthquakes will strike．As a result，a worldwide earthquake-warning network is already in operation and has helped to prepare for the vast destruction that mightotherwise have been totally unexpected．
It is．doubtful，that man will ever be able to control earthquakes and do away with the destructiveness altogether。but as how．and why earthquakes happen become better understood，man will become more and more able to deal with their possible destruction before it occurs．
Most destruction caused by earthquakes is the results of the following EXCEPT__________ ．
A．the collapsing of buildings and the fire it causes’
B．the floods and huge sea waves resulting from earthquakes．
C．the disease that often follows earthquakes
D．the panic brought about by earthquakes

D．there are other phenomena resulting from earthquakes

A．A worldwide earthquake warning network has been set up to avoid major earthquakes.
B．Unusual behavior of animals may be an indication of possible earthquakes．
C．It seeins possible now for scientists to predict when and where earthquakes will occur．
D．Most earthquakes take place on some specific areas of the earth．


24、The author believes that the prediction of earthquakes__________ ．
A．should be more accurate in future
B．is of some help
C．is as a matter offact impossible
D．is really reliable


25、It can be inferred from the last paragraph that the author is chiefly interested in__________ ．
A．controlling earthquakes
B．making earthquakes harmless
C．getting prepared and handling the possible destruction beforehand
