In the 1950s, the development of
antipsychotic drugs called neuroleptics(抑制精神病药物 )radically changed the clinical
outlook for patients in mental institutions who had previously been considered
hopelessly psychotic. Daily medication controlled delusions and made
psychotherapy possible. Many who otherwise might never have left institutions
returned to society. Now physicians have learned that there is a price to be
paid for these benefits. Approximately 10 to 15 percent of patients who undergo
long-term treatment with antipsychotic drugs develop a cluster of symptoms
called tardive dyskinesia (迟发性运动障碍), the most common symptoms of which are
involuntary repetitive movement of the tongue, mouth, and face, and sometimes
the limbs and trunk.
Neuroleptic drugs interfere with the action
of dopamine (多巴胺) , an
A. generally effective but have unwanted side effects
B. gradually replacing psychotherapy
C. experimental and still not widely accepted
D. reserved for the most serious cases of psychosis

{{B}}TEXT A{{/B}} In the 1950s, the pioneers
of artificial intelligence (AI) predicted that, by the end of this century,
computers would be conversing with us at work and robots would be performing our
housework. But as useful as computers are, they’re nowhere close to achieving
anything remotely resembling these early aspirations for human like behavior.
Never mind something as complex as conversation: the most powerful computers
struggle to reliably recognize the shape of an object, the most elementary of
tasks for a ten-month-old kid. A growing group of AI researchers
think they know where the field went wrong. The problem, the scientists say, is
that Al has been trying to separate the highest, most abstract levels of
thought, like language and mathematics, and to duplicate them with logical,
step-by-step programs. A new movement in AI, on the other hand, takes a closer
look at the more roundabout way in which nat A. are capable of reliably recognizing the shape of an object B. are close to exhibiting humanlike behavior C. are not very different in their performance from those of the 50’s D. still cannot communicate with people in a human language
[单项选择] {{B}}TEXT D{{/B}} Imagine eating everything
delicious you want-with none of the fat. That would be great, wouldn’t
it New "fake fat" products appeared on store shelve in the
United States recently, but not everyone is happy about it. Makers of the
products, which contain a compound called olestra, say food manufacturers can
now eliminate fat from certain foods. Critics, however, say the new. eliminate
can rob the body of essential vitamins and nutrients and can also cause
unpleasant side effects in some people. So it’s up to decide whether the new
fat-free products taste good enough to keep eating. Chemists
discovered olestra in tile late 1960s, when they were searching for a fat
that could be digested by infants more easily. Instead of finding the desired
Fat, the researchers created a fat that can’t be digested at all.
Normally, special chemicals in the intestines "grab" molecules of regular
fat and break the A. contains plenty of nutrients B. renders foods calorie-free while retaining their vitamins C. makes foods easily digestible D. makes foods fat free while keeping them delicious
