一、阅读理解。
A
Nowadays more and more people are talking
about genetically
modified foods ( GM foods).
GM foods develop from genetically
modified
organisms (有机体), which have had specific changes
introduced into their DNA by genetic
engineering techniques.
These techniques are
much more precise where an organism is
exposed
to chemicals to create a nonspecific but stable
change.
For many people, the hightech
production raises all kinds of
environmental,
ethical, health and safety problems.
Particularly in countries with long farming
traditions, the idea
seems against nature.
In fact, GM foods are already very much a part
of our lives.
They were first put on the
market in 1996. A third of the corn
and more
than half the cotton grown in the U. S. last year
was
the product of biotechnology, according to
the Department of
Agriculture. More than 65
million acres of genetically modified
crops
will be planted in the US this year. The genetic

is out of the bottle.
However, like any new product entering the
food chain, GM
foods must be subjected to
careful testing. In wealthy countries,
the
debate about biotech is not so fierce by the fact
that they
have a large number of foods to
choose from, and a supply that
goes beyond the
needs. In developing countries desperate to feed
fastgrowing and underfed populations, the
matter is simpler and
much more urgent: do the
benefits of biotech outweigh the risks?
The statistics on population growth and hunger
are
disturbing. Last year the world's
population reached 6 billion.
The UN states
that nearly 800 million people around the world
are unhealthy. About 400 million women of
childbearing age don'
t have enough iron,
which means their babies are exposed to
various birth many as 100 million children
suffer from
vitamin A deficiency, a leading
cause of blindness.
How can biotech help?
Genetic engineering is widely used to
produce
plants and animals with better nutritional values.
Biotechnologists have developed genetically
modified rice and
they are working on other
kinds of nutritionally improved crops.
Biotech
can also improve farming productivity in places
where
food shortages are caused by crop damage
attributable to drought,
poor soil and crop
viruses.
