[填空题] Depression: It Is Real, and It Is Treatable
Depression and the Americans
People with symptoms of diabetes or other physical problems see their doctors for treatment. Those with depression more often than not try to duke it out alone, according to southwest Minnesota mental health professionals, who say the anxiety is prevalent in the region. Depression affects more than 19 million Americans annually, according to the National Institute of Mental Health (NIMH). Yet only one in three people seeks medical treatment.
Defining Depression
Depression is nondiscriminatory (一视同仁的), affecting all ages, sexes and races, local health professionals say. It is a disease -- not a weakness -- that consumes the brain of the chemical serotonin (含于血液中的复合胺) , and it rarely goes away by itself.

Food Fright
Experiments under way in several labs aim to create beneficial types of genetically modified(GM)foods,including starchier potatoes and caffeine-free coffee beans.Genetic engineers are even trying to transfer genes from a cold-water fish to make a frost-resistant tomato.A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes to enjoy the little delicious red fruits again.GM beans and grains supercharged with protein might help people at risk of developing kwashiorkor. Kwashiorkor,a disease caused by severe lack of protein,is common in parts of the world where there are severe food shortages.
Commenting on GM foods,Jonathon Jones,a British researcher,said,"The future benefits will be enormous,and the best is yet to come."
To some people,GM foods are no different from unmodified foods."A tomato is a tomato," said Brian Sansoni,an American food manufacturer.
Critics of GM foods challenge Sansoni's opinion.They worry about the harm that GM crops might do to people,other animals,and plants.
In a recent lab study conducted at Cornell University,scientists tested pollen made by Bt corn,which makes up one-fourth of the U .S.corn crop.The scientist sprinkled the pollen onto milkweed,a plant that makes a milky juice and is the only known food source of the monarch but-terfly caterpillar. Within four days of munching on the milkweed leaves,almost half of a test group of caterpillars had died."Monarchs are considered to be a flagship species for conservation,"said Cornell researcher Linda Raynor."This is a warning bell."
Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides used to protect most of today's crops are sprayed on the crops when needed and decay quickly in the environment.But GM plants produce a continuous level of insecticide.Insect species feeding on those crops may develop resistance to the plants and could do so in a hurry, say the critics.Insects may also develop a resistance to the insecticide Bt.
At the forum on GM food held last year in Canada,GM crops that have been made resistant to the herbicide might crossbreed with wild plants,creating"superweeds"that could take over whole fields.
So where do you stand?Should GM foods be banned in the United States,as they are in parts of Europe?Or do their benefits outweigh any of the risks they might carry?
Paragraphs 1,2&3 try to give the idea that______.
A.GM foods are particularly good to the kwashiorkor patients
B.GM foods may have both benefits and harm
C.we cannot recognize the benefits of GM foods too early
D.GM foods may bring about great benefits to humans
