Hypertension Drugs Found to Cut Risk of Stroke
Australian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of
patients suffering a repeat stroke by more than a third.This is the result of their research.The research,
presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough
in stroke prevention.
Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave
them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to
have a second,often fatal,stroke within five years of the first.
An international six-year study of 6,100 patients directed from Sydney University found that by taking
two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even
taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diu-
retic indapamide( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Coversyl.
The combination was effective even in patients who did not have high blood pressure,the researchers said.
They even found that the risk of another stroke could be cut by three quarters among the one-in-ten patients
who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into
the brain.
Stephen McMahon,who presented the research at the Milan congress of the European Society of
Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those
patients were able to get access to this treatment,it would result in maybe the avoidance of haff a million
strokes a year,"the professor told Australia's ABC Radio.
McMahon said doctors had long known that lowering the blood pressure of those with hypertension could
help prevent strokes."What we have shown for the first time is that it does not really matter what your blood
pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin
with一even for people whose blood pressure is average or below average,"he said.
McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of
patients with strokes一perhaps the biggest step forward that we have made in the last couple of decades."
What patients among those who have a stroke will benefit greatly from taking blood pressure-lowering drugs?
A.Those whose blood pressure is high.
B.Those whose blood pressure is average.
C.Those whose blood pressure is below average.
D.All of the above.

Almost Human?
Scientists are racing to build the world's first thinking robot.This is not science fiction:
some say they will have made it by the year 2020.Carol Packer reports.
Machines that walk,speak and feel are no longer science fiction.Kismet is the name
of an android（机器人）which scientists have built at the Massachusetts Institute of
Technology(MIT).Kismet is different from the traditional robot because it can show
human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored.
Kismet is one of the first of a new generation of androids一robots that look like human
beings一which can imitate human feelings.Cog,another android invented by the MIT,
imitates the action of a mother. However,scientists admit that so far Cog has the mental
ability of a two-year-old.
The optimists（乐观主义者）say that by the year 2020 we will have created humanoids
（机器人）with brains similar to those of an adult human being. These robots will be
designed to look like people to make them more attractive and easier to sell to the public.
What kind of jobs will they do?In the future,robots like Robonaut,a humanoid invented by
NASA,Will be doing dangerous jobs,like repairing space stations.They will also be doing
more and more of the household work for us.In Japan,scientists are designing androids
that will entertain us by dancing and playing the piano.
Some people worry about what the future holds:will robots become monsters（怪物）?
Will people themselves become increasingly like robots?Experts predict that more and more
people will be wearing micro-computers,connected to the Internet,in the future.People
will have micro-chips in various parts of their body,which will connect them to a wide variety
of gadgets（小装置）.Perhaps we should not exaggerate（夸大）the importance of
technology,but one wonders whether,in years to come,we will still be falling in love,
and whether we will still feel pain.Who knows?
What is the writer's attitude to robots in the future?
A.Critical.
B.Hostile.
C.Objective.
D.Enthusiastic.
