A - Listen to a short text about GM foods and assign T (for True) or F (for False):
1. ( ) GM foods is another name we can call transgenic foods.
2. ( ) Genetic modification makes plants more resistant to herbicides,
insects, and pesticides.
3. ( ) Transgenic foods are obliged to have labels.
4. ( ) There is a large variety of transgenic plants on the market, including
soy, corn and cotton.
5. ( ) There is very serious control on the GM food crops.
B - Listen to the recording again and fill in the missing words:
Whether
you realize it or not, several foods you eat today are products of
_______________ modification. By inserting genes from one plant into another,
scientists have succeeded in creating plants which are _______________ to
herbicide and insects or have a higher _______________ to heat, cold and
drought. Soy, corn, cotton, _______________, and tomatoes are only some of the
crops that have already been modified. This _______________, however, has
caused a lot of _______________.
One side
argues that genetic modification of food can help the _______________ because
transgenic (or GM – genetically modified) foods reduce the use of
_______________ and pesticides. Besides, these GM foods can have a higher
_______________ value. Consequently, they can make it easier to _______________
the world.
The
other side questions the real _______________ of the new technology
_______________ that there isn’t _______________ testing and regulation of GM
foods, and _______________ us about the risk of unexpected _______________.
They point out, for example, that GM _______________ resistant to insects kill
not only the _______________ insects, but also the _______________ ones. And
what if the insect resistant crop _______________ the weeds and the weeds, in
turn, became resistant to _______________ herbicides?
Despite
all the _______________, GM foods are already on the market, and
_______________, sometimes you won’t even have the _______________ of not
buying them because the _______________ of GM foods is not required in all
countries. And then you won’t know if the product has been _______________
modified.
