The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world's predicted population growth to ten or eleven billion.It's not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.
It may well be that in the long term it is the developing world that benefits most from GM foods.It's true that for the next ten years or so GM crops may be too expensive.But the lesson of personal computers is applicable here—once the technology has been developed for money-spinning crops, like maize, soybeans and cotton, it will filter down and become affordable for all.This doesn't mean, unfortunately, that famines will disappear, but severity and duration will be helped by an improved ability to produce and distribute food.

Module 2 DNA-the Secret of LifePart One: Teaching Design第一部分:教学设计Goals●To develop the students’ reading ability●To know something about DNA●To master the use of the, this, it, now, was\were, much●To help the students how to write science materialsPeriod 1: Production and reading(DNA—the Secret of Life)ProceduresStep 1: Warming up1. Warming up by questioning1)Why do people take after their parents in personality?2)Who do you look like, your mother or your father?3)Are you similar to your sisters\ brothers in appearance or personality?2. Warming up by discussingBoys and girls, today we are going to learn something about DNA. Do you have ever heard about it? Before you read the passage, I’d like to give you some questions to discuss.Has the discovery of DNA been called the most important biological work of the last 1oo years? Why?Yes. It has already had and will continue to have an enormous influence on our lives. We have already experienced the benefits from it for many years. For example, We can find the murders by DNA testing. We can decide the children we want by genetic engineering.Does the discovery of DNA worry you?No. We can use the new technology of genetic engineering to create the characteristics we want. If we insert new genes into unborn babies, children or adults, the baby will be cleverer, the adult will be more healthy, and they will do anything better.Yes. If we choose the characteristics of our babies, we are changing nature in a very direct way. What might theconsequences be? The technology of DNA might cause many social problems.Are you for or against GM food? Explain why.I am for GM food. If a gene for resistance to drought is put into wheat or maize, then a crop highly resistant to drought can be produced. Crops with certain genes can kill pests. Thus, we can produce enough food for those hungry people.I am against GM food. Scientists have found that a crop with a gene that kills pests can leave a poison in the soil that kills harmful as well as helpful insects. GM crops may affect the environment by producing chemicals or carcinogens. I think GM food is not safe, and it may have side effects. So I am in favor of banning GM food. What should we do about GM food in China?My view is that we should not produce too much GM food in China. The government should control and regulate GM food. For example, the market places should put labels on GM products to make the consumers know what kind of food they are buying. I don’t think it is a good idea to import GM products from foreign countries. We’d better use GM products cautiously.3. Warming up by studying vocabularyTurn to the vocabulary behind this module, and study the new words and expressions, paying attention to the relationship between the spelling and the pronunciation.Step 2:Pre-reading1. ImaginingWell, just suppose we have advanced technology of DNA, and what can we do with the genetics engineering? Imagine you are a boy/girl with other’s genes inserted in your body before you were born. Do you feel…? If an ath lete is inserted a lion’s gene, can he/she run faster than normal human beings?2.Introduce some new wordsShow the following new words from the text, and ask the students to read each word twice together, correcting their mistakes in their pronunciation.Now, lets have a spelling quiz. Read the following sentences first, then fill the blanks, using their proper forms. 1）We can’t a____ nature in this way.These new genes will create new c____.2〕What’s the b____ of learning English?3〕If you insert new genes into someone, what will the c____ be?4〕We are a____ to succeed in the match.5〕We should do something to stop polluting the e____.6〕Scientists have now shown that some t____ are strongly influenced by our genes.7〕DNA testing can help in criminal i____.(keys: 1.alter, 2.characteristics, 3.benefits, 4.consequence, 5.ambitious, 6.environment, 7.traits, 8.investigations) Step 3: Reading1.Leading-inWe have already talked something about DNA as well as genetics. I also think you are clear about GM foods. You may have good ideas about genetic engineering. Now, please read the following passages (Part1-3), then answer the following questions according to the passages.1)When he mitted the murder, Waters left some of his own cells on his victim. What were scientists able to do as a result?2)Why doesn’t Mark deserve to be a world champion?3)Why did Clara have hospital test?4)How much GM food is there in China?5)What is the risk of producing a GM crop which kills pests?6〕Is it hard for scientists to predict how GM crops will affect the environment?2. Fast reading for the general ideaWell, please find out the main ideas of the passages (Part1-3)Key to Part1: Scientists have found the answer to one of the most important questions of biology. That is how living things reproduce themselves.Key to Part2: Science can find out murders by using DNA testing.Key to Part3: Science can use the technology of genetic engineering to insert new genes into human beings to decide the characteristics that they want.)3. Listen to the tape of the text and try to find the following words and expressions that appear in the passage.(keys: mit a murder, pregnant, hereditary, perform an operation, reproduce, victim, alter, insert, consequence, field, benefit, structure)4. Detailed reading for informationRead the following sentences and decide whether they are true (T) or false (F) according to the text.1) In fact, Crick and Watson didn’t find the answer to how living things reproduce themselves.2) People can find murders by paring DNA.3) People can have good-looking, very intelligent children by using a technology called genetic engineering.4) If an athlete is inserted an animal gene into his body, he would run faster.5) Genetics is a science that has already caused and will cause great changes in our life. As a result, there are many important issues to discuss.(keys:1F 2T 3T 4T 5T)Step 4: Reading practiceRead the following passage within 5 minutes and make a better choice to each question.Want a glace of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient----no matter where he or she is.On line doctors offering advice based on normal symptoms(症状) are the most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient.A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient’s important signs over the phone. With this kind of equipment, the cry asking whether there was doctor in the house could well be a thing of the past.Other medical technology groups are working on applying telemedicine to rural care, and at least one team wants to use telemedicine as a tool for disaster need----especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.But there is one problem. Bandwidth(宽带) is the limiting factor for sending plex medical pictures around the world,----Cu---See Me photos being one of the biggest bandwidth users. munication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both thesecond-generation Internet and third-generation mobile phones for the future of remote medical service.Doctors have met to discuss puter----based tools for medical diagnosis, training and telemedicine. With the falling price of broadband munications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’ opinions and diagnosis are mon.1. The writer chiefly talks about____.A．the use of telemedicine B. the on-line doctorsC. medical care and treatment D munication improvement2. The basis of remote diagnosis will be____.A.personal date assistanceB. some words of a patientC. real physiological informationD. medical pictures from the Internet3. Which of the following statement is TRUE according to the text?A.Patients don’t need doctors in hospital any more.B.It is impossible to send a patient’s signs over the telephone.C.Many teams use telemedicine dealing with disasters now.D.Broadband munications will bee cheaper in the future.4. T he “problem〞in the fourth paragraph refers to the fact that____.A.bandwidth isn’t big enough to send plex medical picturesB.the second-generation of Internet has not bee popular yetC. munication satellites can only deal with short term needsD. there is not enough equipment for spreading the medical care(keys: 1.A 2.C 3.D 4.A)Step5: homework1. Repeat the text.2. learn the new words again, using the dictionary if necessary.。
