A tomato that is redder than other tomatoes A tomato that grew more quickly than other tomatoes A tomato that is less vulnerable to insects a) b) c) Whom does Ralph trust? The natural world His mother Women who have been mothers WHAT ELSE DOES IT MEAN? pest The word “pest,” in this podcast, means an insect or rodent (small animal) that destroys crops, spreads disease, and causes other types of harm or problems for humans: “Pests destroyed their wheat crop, so next year they’re planning to plant something else.” A “pest” is also an annoying person who will not leave one alone: “My little sister Dynee was a major pest when we were growing up, but now we’re good friends.” As a verb, “to pester” means to annoy someone repeatedly, possibly asking for something again and again: “Stop pestering your boss for a raise! Instead, focus on performing your job really well to earn a raise, instead of always just asking for one.” Or, “I hate the way marketers always call at mealtime to pester us with whatever they’re selling.” to trust In this podcast, the verb “to trust” means to rely on someone, or to believe that someone is good or honest and will not anything to hurt oneself: “Do you trust your teenagers to behave while you and your wife are gone for the weekend?” The verb “to trust” also means to believe that something is true or accurate: “If we trust their numbers, the business appears to be doing very well.” The phrase “to trust (someone) with (something)” means to entrust, or to let someone have control over something because one knows they will treat it well: “I’m going to trust you with this expensive necklace, because I know you’ll be careful with it.” Finally, the phrase “tried and trusted” describes something that has been done many times and is proven to work well: “This software is a tried and trusted solution for identifying security threats to a website.” These materials are copyrighted by the Center for Educational Development (2013) Posting of these materials on another website or distributing them in any way is prohibited English as a Second Language Podcast www.eslpod.com ESL Podcast 881 – Eating Genetically Modified Foods CULTURE NOTE Genetically Modified Crops Several genetically modified “crops” (plants grown for food or clothing) have been approved for “consumption” (use, especially through eating) For example, “papaya” (a large, tropical fruit with orange flesh and large, round, black seeds) has been genetically modified to resist a virus that was threatening to “destroy” (ruin) the papaya industry in Hawaii Today, 80% of the papaya grown in Hawaii is this genetically modified type About 13% of the “zucchini” (a long, green vegetable) grown in the United States is also genetically modified for resistance to viruses Many “cooking oils” (liquid fat used for cooking other foods) are made from genetically modified crops, such as soybeans, and corn “High fructose corn syrup” (a sugar substitute made from corn) and other products are also made from these genetically modified crops A lot of the sugar produced in the United States is also “derived” (made) from genetically modified crops, particularly sugar beets, which have been genetically modified to be more “tolerant to” (not affected by) “herbicides” (chemicals used to kill “weeds” (unwanted plants)) The sugar produced from genetically modified crops is chemically identical to “conventional” (produced in traditional ways, without the use of genetic modifications) sugar, but some people remain concerned about the “consequences” (what happens as a result) of consuming genetically modified foods As of 2012, no genetically modified animals have been approved for consumption, but the “FDA” (Food and Drug Administration, a U.S government agency) is considering approval of genetically modified “salmon” (a type of fish with pink meat) for consumption Comprehension Questions Correct Answers: – c; – a These materials are copyrighted by the Center for Educational Development (2013) Posting of these materials on another website or distributing them in any way is prohibited English as a Second Language Podcast www.eslpod.com ESL Podcast 881 – Eating Genetically Modified Foods COMPLETE TRANSCRIPT Welcome to English as a Second Language Podcast number 881: Eating Genetically Modified Foods This is English as a Second Language Podcast episode 881 I'm your host Dr Jeff McQuillan, coming to you from the Center for Educational Development in beautiful Los Angeles, California Our website is ESLPod.com Go there and look at the ESL Podcast Blog as well as our special courses in daily and business English This episode is a dialog between Ralph and Nicky, about eating what is called genetically modified foods Let’s get started [start of dialog] Ralph: What’s that? Nicky: It’s a bigger and better tomato It’s been genetically modified Ralph: You’re not going to eat that, are you? Nicky: Of course I am I’m making a salad Want one? Ralph: No way I don’t want to eat something that’s been genetically engineered in a laboratory Who knows what kind of strange DNA it has Nicky: It’s perfectly safe It’s been modified to grow faster, have more nutrients, and be resistant to disease and pests Ralph: And it may contain strange mutations as part of its genetic makeup that they didn’t tell you about I really wouldn’t eat that if I were you Nicky: Where did you get this aversion to genetically modified foods? Scientists and farmers have always used selective breeding with animals and crops to bring you bigger and better food This is nothing different Ralph: Of course it is And just because it’s bigger, doesn’t mean it’s better I’ll eat food that’s been modified by the only person I trust Nicky: Who’s that?

[end of dialog] Our dialog begins with Ralph saying to Nicky, “What’s that?” Nicky says “It's a bigger and better tomato.” A tomato is something that you might eat with a salad or on a sandwich, or use to make sauce for your pasta Nicky says “It's a bigger and better tomato It's been genetically modified.” “To modify” (modify) means to change something “To genetically modify something” means to change the genes, if you will, the components of a plant or an animal that determine what kind of plant and animal that is “Genes” (genes) are what we might call the building blocks of life They’re the basic components, the elements that life is constructed on It's hard to explain that in a very complete manner here, but that's what “genetically” means related to your genes Ralph says, “You're not going to eat that, are you?” Ralph doesn't think Nicky should eat it Nicky says, “Of course I am I'm making a salad Want one?” – meaning you want one? Ralph says, “No way.” “No way” is a very strong way of saying “No, absolutely not.” “No way I don't want to eat something that's been genetically engineered in a laboratory.” “To engineer,” (engineer) as a verb, means to change, to usually change the structure of something “Genetically engineered” would be something where scientists have changed the genetic makeup, the genetic composition of that particular plant or animal A “laboratory” is a place where scientists experiments Ralph says, “Who knows what kind of strange DNA it has.” “DNA” is the chemical substance that carries the genetic information It's what carries the information from our genes that affects our eye color, our skin color, our physical makeup and so forth Nicky says that, “This tomato is perfectly safe.” It's completely safe “It's been modified to grow faster, have more nutrients and be resistant to disease and pests.” So, Nicky is saying the tomato is safe “It has been changed only to make it grow faster to give it more nutrients, and to make it resistant to disease and pests.” “Nutrients” (nutrients) is a general word used to describe the substances or the elements within a plant that help you grow, that animals eat, or humans eat that helps their body grow better It could be a lot of different things Each food would have different kinds of nutrients Nicky says that the tomato was also modified to be resistant to disease and pests “To be resistant” means that you are not easily damaged by something, These materials are copyrighted by the Center for Educational Development (2013) Posting of

easily harmed by something “Disease” is the same as sickness or illness, when something is not growing and functioning the way it should “Pests” (pests) are insects or small animals that destroy plants, that destroy the plants that we use to get food from So pests are always bad things, whether they’re mosquitoes or rodents or any other sort of animal that is going to harm the plants that we are growing to eat Ralph says, “And it may contain strange mutations as part of its genetic makeup that they don't tell you about.” Ralph is saying that these genetically modified foods are dangerous because they may contain strange mutations A “mutation” (mutation) is a genetic change that makes one individual different from another individual But it's not, if you will, a change that you would expect to take place So, usually mutation, when we're talking about science fiction, for example, is when something changes in some weird way, some strange way that is considered dangerous or unusual Mutation is part of the way that the world works in terms of DNA and genes, but here Ralph is using the word as a negative, as a criticism of this genetically modified food Ralph says that these mutations could be part of the tomatoes’ genetic makeup We’ve already talked about what “genetic” refers to “Makeup” (makeup) – one word – refers to composition what something is made of Ralph says, “I really wouldn't eat that if I were you.” That's a common expression, “If I were you” – if I were in your situation, I would not that Nicky says, “Where did you get this aversion to genetically modified foods?” An “aversion” (aversion) is a hatred or strong dislike of something, something that you would want to avoid Nicky says, “Scientists and farmers have always used selective breeding with animals and crops to bring you bigger and better food This is nothing different.” “Selective breeding” (breeding) is the practice of making plants or animals reproduce, or produce new plants or animals that have particular characteristics that you want to increase So, if you have two different kinds of dogs and you want to make a dog that is a mixture of these two kinds of dogs, well, you would put the two dogs together – one would have to be male and one would have to be female, of course – and let them what they do, and then you would “breed” a new animal, a combination of these two different animals “Selective breeding” is using that basic logic, that basic process with plants or animals, in order to produce plants or animals that have certain characteristics That's what Nicky says farmers and scientists have been doing for many years and that this is nothing different Ralph says, “Of course it is.” “And just because it's bigger” – meaning, the tomato – “doesn't mean it's better I'll eat food that's been modified by the only person I These materials are copyrighted by the Center for Educational Development (2013) Posting of these materials on another website or distributing them in any way is prohibited English as a Second Language Podcast www.eslpod.com ESL Podcast 881 – Eating Genetically Modified Foods trust.” “To trust” means to believe, in this case, or to rely on Nicky asked, “Who’s that?” – who is that person that you trust? Ralph responds, “Mother Nature.” Mother Nature is not a real person We say “Mother Nature” to refer to the idea that the whole world, the natural world is somehow controlled by this female figure, I guess Mother Nature refers to the way the environment is, the way nature is without people interfering with it, without men and women making changes to the environment That's basically the idea behind this term “Mother Nature.” Ralph treats Mother Nature as a real person that he can trust What he's really saying here is that he only wants to eat food that is somehow natural, that doesn't have any sort of either chemicals, perhaps, or genetic modifications that would change the way the food is produced Now let’s listen to the dialogue this time at a normal speed [start of dialog] Ralph: What’s that? Nicky: It’s a bigger and better tomato It’s been genetically modified Ralph: You’re not going to eat that, are you? Nicky: Of course I am I’m making a salad Want one?
