基因改造食物安全吗？
- 鼓吹基因改造作物的人说，这类作物不像传统作物，需要的有毒农药较少，对环境有利。但令批评者担忧的是潜在的风险，他们想知道所谓的利益究竟有多少。到底基因改造作物是环保美梦的实现，还是一场正在形成中的灾难？科学家正积极寻找答案。
人们对基因改造食物的态度，似乎愈来愈壁垒分明，一边的人支持，另一边的人则是畏惧。支持者宣称，种植基因改造作物对环境伤害较小，而食用这种农作物制成的食品也完全无害。它们还说，基因工程让农作物在贫瘠的土地上也能生长，或可培育出更营养的食物。在不久的未来，全球人口快速膨胀，还得靠这方法解决粮食问题。持怀疑态度者则反驳，基因改造作物对生态环境或人体健康都有极大的风险，令人忧心，不该贸然接受。许多欧洲国家抱持这种态度，因而*基因改造作物的种植与输入。主要的争议，集中在基因改造食物的安全性。然而，最近的科学研究又是如何看待基因改造食物的危险呢？答案，往往迷失在各种报导的争议中；但是在接下来的篇幅里，它们将呈现在你的眼前。
GENETICALLY MODIFIED FOODS: Are They Safe?
- Are genetically modified crops an environmental dream come true or a disaster in the making? Scientists are looking for answers
The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering－which can ince plants to grow in poor soils or to proce more nutritious foods－will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health－risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural procts. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards? The answers, too often lost in reports on the controversy, are served up in the pages that follow.

到国外的关于的自动化的杂志的网站上copy一篇文章的摘要就可以了
找了一个自动化杂志的网站，你随便找个文章的摘要应该都符合你的要求。
http://www.actapress.com/Content_Of_Journal.aspx?JournalID=62
例如下面的摘要
The
authors
develop
and
test
a
multiclassifier-based
near-real-time
face
detection
system
based
on
the
premise
that
a
three-part
strategy
is
necessary
for
designing
real-time
face
detection
systems
that
provide
high
detection
rates.
The
critical
factors
for
real-time
face
detection
are
based
on
a
framework
of
multiple
classification
functions:
(1)
a
skin
classification
function
is
used
as
the
preliminary
stage
in
order
to
prune
the
search,
localize
the
computation,
and
therefore
improve
performance
time;
(2)
subsequently,
three
coarse-to-fine
statistical
model
based
classifiers
are
used
to
scan
the
windows
and
discard
most
non-face
windows;
and
(3)
finally,
faces
and
non-faces
are
veri??ed
from
images.
The
bagging
ensemble
algorithm
(bootstrap
aggregating)
is
also
applied
to
improve
the
performance
of
detection
rates.

Six a day to improve immunity
Sleep a good sleep: sleep bad and lower the immune system. T cells in the body responsible for dealing with viruses and cancer, if it is not enough sleep, T cells will rece the number of increased risk of illness. Do not have to睡足eight hours, as long as the morning wake up can feel the spirit of ease.
Do some sports: sports daily 30-45 minutes, will increase the number of immune cells, will be a corresponding increase in resistance. However, the movement is too intense or if more than one hours time, the body will proce hormones, suppress immune system activity.
Do a massage: massage to relax the body, recing stress. Daily 45-minute massage, a month later, there will be significant improvement in immune function.
Make a return to daydreaming: 5 minutes a day of daydreaming while deep breathing while doing build castles in the air, so pleasant screen passes from the brain, immune cells can increase the number and activity.
To participate in an art activity: a marked increase in interferon can laugh, immune cells become more active. If the claims lack a sense of humor, you can see more comedy, funny cartoons. Music can increase the fight against infection and cancer of the antibody, regardless of what kind of music like to listen to when the health of all physiological responses to stimulation.
Exchange with a friend: a friend and more people, not only is not easy to colds, immune function than those who eccentric character well. Some studies have shown that good social relations will be concive to fight against pressure, recing stress, affects the immune cell function.
