Long-s doctrin holds that we are protected from fungi not just by layered immune defenses but ( e ) we are mammals*, with core temperatures higher than fungi prefer. The cooler outer surfaces of our bodies are at risk of minor assaults-think of athlete's foot*, yeast infections, ringworm*-but in people with healthy immune systems, invasive* infections have been ( f ). That may have left us overconfident. "We have an enormous (g) spot," says Arturo Casadevall, a physician and molecular microbiologist at the Johns Hopkins Bloomberg School of Public Health. "Walk into the street and ask people what are they afraid of, and they'll tell you they're afraid of bacteria, they're afraid of viruses, but they don't fear dying of fungi." Ironically, it is our successes that made us vulnerable*. Fungi exploit damaged immune systems, but before the mid-20th century people with impaired immunity didn't live very long. Since then, medicine has gotten very good at keeping such people (h), even though their immune systems are compromised by illness or cancer treatment or age. It has also developed an array of therapies that deliberately suppress immunity, to keep transplant recipients healthy and treat autoimmune* disorders such as lupus* and rheumatoid arthritis*. ( i ) vast numbers of people are living now who are especially vulnerable to fungi. Not all of our vulnerability is the fault of medicine preserving life so successfully. Other ( j ) actions have opened more doors between the fungal world and our own. We clear land for crops and settlement and perturb* what were stable balances between fungi and their hosts. We carry goods and animals across the world, and fungi hitchhike on them. We drench crops in fungicides* and enhance the resistance of organisms residing nearby. (s) ELSE

One recent Halloween my five-year-old son entered a *pumpkin-decorating contest at his school. He proudly took his entry to his school. It was a wild combination of *carvings, paint and feathers which he had constructed himself. We placed it among the other creative pumpkins witches, a snowman, and even a 5 bubble-gum-blowing pumpkin (wearing a baseball cap. I thought that the judges were going to have a tough time choosing a winner. They must have thought the same thing, because when we returned to the school that evening, we discovered all the pumpkins had been awarded the same black-and- gold ribbon>My son, eagerly looking to see if his entry had won, kept asking me, 10 "Which pumpkin won? Where's the winner?” What could I say? "Well, it looks like everyone won. Look. You got a ribbon, son!" Kids are smart. "Yeah, but who won?" he asked. I could sense his disappointment - and my own. Why have a contest if you're not going to pick a winner? > I understand that the school was trying to convey that everyone had done a great 15 job, but I worry [that (3)ª a different message was sent that losing is a hardship no one O should face 7

6限目 150点 TR/35-40 次の英文を読み, 問いに答えなさい。 ( 50点) Most people in the United States don't realize that they've been eating *genetically engineered foods since the mid-1990s. More than 60% of all processed foods on U.S. - supermarket shelves - including pizza, chips, cookies, ice cream, salad dressing, contain ingredients from engineered soybeans or corn syrup, and baking powder - 5 corn. Genetic change or modification is not a recent thing. Humans have been (5a)altering the genetic structure of plants for a few thousand years, keeping seeds from the best crops and planting them in following years, *crossbreeding varieties to make them taste sweeter, grow bigger, and (5b)last longer. (1)In this way we've transformed the 10 wild tomato from a fruit the size of a grape to today's giant, juicy tomatoes. But (2)the technique of genetic engineering is new, and quite different from conventional breeding. Traditional breeders mix together related organisms whose genetic structures are similar. In so doing, they transfer a great number of genes. By contrast, today's genetic engineers can transfer just a few genes at one time between 15 species that are distantly related or not related at all. Genetic engineers can pull a desired gene from almost any living organism and insert it into almost any other organism. They can put a rat gene into lettuce to make a plant that produces vitamin C or blend genes from an insect into apple plants, The purpose offering protection from various diseases that damage apples and pears. 20 is the same: (3) to insert a gene or genes from one organism carrying a desired characteristic into another organism which does not have that characteristic. between The engineered organisms that scientists produce by transferring genes species are called transgenic organisms. Several dozen transgenic food crops are (5e)currently on the market, including varieties of corn, pumpkin, soybeans, and 25 cotton. Most of these crops are engineered to help farmers deal with age-old agricultural problems: weeds, insects, and disease.
