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 genie
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.
