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-winter 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 Sansonis 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 butterfly 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 todays 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 food 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?

Mom's Traffic Accidents?
The bicycling craze came in when were just about the right age to enjoy it. At first even "safety" bicycles were too dangerous and improper for ladies to ride, and they had to have tricycles. My mother had (I believe) the first female tricycle in Cambridge; and I had a little one, and we used to go out for family rides, all together; my father in front on a bicycle, and my poor brother Charles standing miserable on the bar behind my mother. I found it very hard work, pounding away on my hard tyres; a glorious, but not a pleasurable pastime.
Then, one day at lunch, my father said he had just seen a new kind of tyre, filled up with air, and he thought it might be a success. And soon after that everyone had bicycles, ladies and all; and bicycling became the smart thing, and the lords and ladies had their pictures in the papers, riding along in the park, in straw boater hats.
My mother must have fallen off her bicycle pretty often, for I remember seeing the most appalling cuts and bruises on her legs. But she never complained, and always kept these mishaps to herself. However, the great Mrs. Phillips, our cook, always knew all about them; as indeed she knew practically everything that ever happened. She used to draw us into the servants hall to tell us privately. "Her Ladyship had a nasty fall yesterday; she cut both her knees and sprained her wrist. But don't let her know I told you. " So we never dared say anything. Similar little accidents used to occur when, at the age of nearly seventy, she insisted on learning to drive a car. She never mastered the art of reversing, and was in every way an unconventional and terrifying driver. Mrs. Phillips used then to tell us: "Her Ladyship ran into the back of a milk-cart yesterday; but it wasn' much hurt"; or "A policeman stopped her Ladyship because she was on the wrong side of the road; but she said she didn't know what the white line on the road meant, so he explained and let her go on." Mrs. Phillips must have had an excellent Intelligence Service command, for the stories were always true enough.
n did not ride bicycles at first because
A) they demanded too much hard work.
B) they were considered unsafe and unladylike.
C) tricycles were more enjoyable.
D) tricycles could carry young children as well.
37. How did the writer feel about tricycles?
A) They were very hard to ride.
B) They were safer and more convenient for women.
C) They were not as fast as bicycles.
D) They were not proper for women to ride.
ying became popular when _____ .
A) the writers father popularized it
B) air-filled tyres began to be used
C) aristocratic people started enjoying it
D) newspapers had pictures of cyclists
writer admires Mrs. Phillips because _____ .
A) she was an excellent cook
B) she was in command of all the servants
C) she could keep secrets
D) she knew everything that went on
40. The writer's mother always had car accident later because _____ .
A) she could not control the car
B) she was very old then
C) she did not understand the road system
D) she behaved arrogantly
