The chocolate industry is huge. People eat millions of kilograms of chocolate each year. The UAE is no exception. In fact, experts say that the consumption of all kinds of chocolate is increasing in the UAE. It is now a 200 million dirham industry. Most people think of chocolate as a delicious treat but did you know that it is also good for you? 2 The idea that chocolate is healthy actually began hundreds of years ago. People in South America made a drink from chocolate. However, this chocolate was not sweet. Later, doctors in Europe gave chocolate to their patients. They thought that it would help people who were too thin, too tired, or had problems digesting their food. 3 In the 1900s, people thought chocolate was unhealthy. For example, many people thought that chocolate caused acne, or pimples. However, this is a myth. They also thought that chocolate was bad for your teeth. This isn t true either. Actually, studies show that milk chocolate is one of the snack foods that is the least likely to contribute to tooth decay. 4 New research shows that chocolate has other health-giving effects. There are three main benefits of chocolate. First, it contains flavanols, which are healthy chemicals that can lower blood pressure. Secondly, research shows that chocolate can help people metabolize sugar. People with diabetes cannot metabolize sugar very well, but when they eat chocolate their ability to metabolize sugar improves. Thirdly, when people eat chocolate their serotonin levels increase. Serotonin is a hormone in the brain which makes people relaxed and happy. Not all chocolate has the same effect, however. These studies were all done using dark chocolate. In order to get the maximum benefit from chocolate, you should eat dark chocolate. 5 A word of caution is necessary. Most chocolate is made with a lot of fat and sugar. Fat and sugar have a lot of calories. If you are trying to lose weight for your health, you should eat fewer calories. This means that if you include chocolate in your diet, you should eat less of something else. Reading Skill: Paragraph Topics 4.1 What is the topic of each paragraph?

6 The Industry: How Chocolate is Made 4.12 The text below includes several passive sentences. Underline them.the first one has been done for you. We all love chocolate, but have you ever wondered where it comes from? Fifty million people are supported by the chocolate industry. This means that 50 million people make money from chocolate. That s a pretty big industry! Chocolate is made from cocoa. Most cocoa is produced in western Africa. Forty-three percent of the world s cocoa is from the Ivory Coast billion tons of cocoa is produced each year. About two thirds of that is used to make chocolate. The cocoa bean itself is very bitter. Many things have to happen for it to become the sweet treat we enjoy. First, the cocoa beans are harvested (taken from the plants). Then, the flavor of the cocoa is developed by a process called fermentation. The different flavors of chocolate are created by changing the time and temperature during the roasting process. Cocoa is then made into cocoa solids and cocoa fat. Sometimes, to save money, different fats are added to the chocolate. Wax is sometimes added to prevent the chocolate from melting too fast. Finally, different flavors, like orange, mint, or nuts are added. About 80% of chocolate in the UAE is imported from other countries. Most of it is made in Europe or the United States. Although people in the UAE are eating more and more chocolate, most chocolate is consumed by people in Western countries. People in Europe, for example, consume 40% of the world s chocolate. Noticing the Grammar: Passives 4.13 Look at the text for the answers to the following questions. If the answer is not in the text, write we don t know. 1 Who does the chocolate industry support? 2 Who makes chocolate? 3 Where is most cocoa produced? 4 Who produces the cocoa? 5 Who harvests the cocoa? 6 What develops the flavor of the cocoa? 7 Who makes the cocoa into cocoa solids and cocoa fat? 8 Who adds the wax to the chocolate? 9 Who imports the chocolate to the UAE? 10 Who consumes most of the world s chocolate? 11 The passive is used we do not know is doing the action. We also use it when the action, or the object of the sentence is more important. Past 4.14 Participles To write in the passive voice, we use past participles. For each of these verbs, write the past participle. When you are finished, write some passive sentences of. 1 love loved 2 amaze 3 support 4 make 5 produce 6 use 7 develop 8 create 9 take 10 speak 11 build 12 give 13 steal 14 eat

7 Active to Passive 4.15 Change these sentences from active to passive voice. You don t need to include the word someone or people in your passive sentences, but remember to use by if the person doing the action is named. Make sure you use the same tense, also. 1 Someone gave me a bicycle for my birthday. 2 People usually eat turkey in America at Thanksgiving. 3 Someone imports Renault cars from France 4 People have held a national day party in my school every year since Someone built the hotel last year. 6 The principal will give out the prizes on the last day of the competition 7 Someone is repairing my car right now. 8 Your teacher will mark your exam papers this week 9 My mother made this cake 10 Someone is showing the films in the Al Muroor Cinema Mixed Grammar 4.16 These questions are very similar to real grammar questions on the CEPA exam.

10 Writing Task: Reflection 4.17 Look at the sample essay and answer the questions below. Many schools around the world have banned sweets and other junk food from their cafeterias. This has both advantages and disadvantages. First, I will discuss the disadvantages. Children love junk food because it is tasty. If junk food is banned from school cafeterias, students will not be able to eat what they like. Perhaps they will not eat at all. In addition, people have different ideas about what is junk food and what is okay to eat. It would be difficult to decide what foods to ban and what to allow in the schools. There are some advantages to this plan, however. The number of overweight and obese students is increasing every year. There are also high rates of diseases like diabetes in the UAE. Many of these problems can be avoided if people learn about good nutrition at a young age. The best place to learn this is in school. In addition, the government can help keep children healthy by providiing fruit, vegetables, and other healthy food instead of chips and chocolate in school. In conclusion, while banning junk food from school cafeterias has both advantages and disadvantages, the advantages clearly outweigh the disadvantages. The UAE government should try to do this as soon as possible. 1 How many paragraphs does this essay have? 2 How many paragraphs does your essay have? 3 Which come first in this essay advantages or disadvantages? 4 Which comes first in your essay? 5 This student wrote: the advantages clearly the disadvantages. (This is the same as saying that the advantages are more powerful than, or better than, the disadvantages.) 6 Does this student think that junk food should be banned in schools? Look at the sentences below. Could they go in this essay? If so, where? Label each sentence: Introduction, Conclusion, Advantage, Disadvantage, or Not In This Essay. 7 More healthy food could be available if school cafeterias stopped having junk food. 8 The UAE could save money if students were healthier because of healthier food. 9 I believe that students choice is more important than making them eat healthy food. 10 Children will dislike school because they will not be able to eat what they like. Memorizing Essays: Don t waste your time! Don t waste your time memorizing an essay. Each CEPA exam has a different writing question and a different question type. If you use a memorized essay, you will not be able to answer the question correctly. Instead, prepare for the CEPA writing section by practicing often. You can show your teacher your essays. The people who mark the CEPA test always know when an essay has been memorized. Memorized essays always get a low mark. CEPA Tip!
