(Last May Day Holiday, I went to Beijing, I climbed up the Great Wall. It was terrible. I still remember the terrible experience till now. I got up early that day so that I could leave and get to the Great Wall early with my husband and my daughter. My husband drove the car. There was too much traffic on the road. When we got there, we found that there were too many people on the Great Wall. We climbed slowly. We wanted to take photos but we couldn’t. Do you want to know why? Please look at the photos. T: What’s the problem? Ss: There are too many / thousands of people. T: That’s the population problem. In this class, we are going to learn Module 11 Population. T: Is Beijing the biggest city in China? Ss: No, it isn’t. T: Do you know which the biggest city is in China? Ss: Chongqing. T: OK! Let’s learn together! Step Ⅱ Listening and vocabulary learning Vocabulary learning Ask the students to look at the photo in Activity 1. Use the words in the box to describe it. · Invite one student to read the words and let the others read after him or her. · Make sure the students can read correctly. · Make sure they know the meaning of the words. · Show some pictures to help them to learn the new words. . HYPERLINK "http://image.baidu.com/i?ct=503316480&z=0&tn=baiduimagedetail&word=pollution&in=60&cl=2&cm=1&sc=0&lm=-1&pn=59&rn=1" \t "_blank" INCLUDEPICTURE "http://t2.baidu.com/it/u=2442926763,260868886&gp=-48.jpg" \* MERGEFORMAT pollution After the students are familiar with the words, the teacher should encourage them to describe the photo. Sample: There are crowds (of people) in the shopping mall and there is not enough space . There is too much noise. They are making a lot of noise. The population of many countries is increasing quickly. The increasing population needs more space. There are too many people so there is too much traffic, noise and pollution. After giving the model, the teacher should encourage the students to make sentences with these words. Then let them do Activity 6 on page 89: complete the sentences with the words in Activity 1. Sample answers: 1. population 2.smoke 3. crowd 4. traffic 5. space 6. increase Listening In this step, students will listen to the tape and choose the best answer. Firstly, ask students to open their books and turn to page 88, read the questions and answers in Activity 2, and make sure they understand the sentences clearly to help them listen to the tape and choose the answers more easily. Secondly, play the tape for the students to listen and choose the answers. The students should try to find the answers and improve the listening skills. The teacher plays the tape recorder for students. Check the answers with the whole class. Thirdly, play the tape once more and pause after each phrase, asking the students to repeat chorally and individually to help the students learn and use the new words. Step Ⅲ Listening and reading Ask students to listen to the conversation and complete the table in Activity 4 and choose the best summary of the conversation in Activity 5. Listening In this procedure, the students will listen to a dialogue among Tony, Daming, Lingling and Betty with their books closed. They look up some facts about the increasing population and talk about the other problems of pollution, traffic and noise. T: Listen to the recording carefully, and you can read after the recording, and at the same time you must pay attention to the numerals in the dialogue. Play the tape for students again, ask students to listen to the recording and complete the table in Activity 4. Play the recording a third time for students listen and check. Check the answers with the whole class. Sample answers: People in the world Babies born every minute 259 Babies born every year 136,130,400 Population of China about 1,300,000,000 Population of the world about 6,500,000,000 T: Now, please look at the table that you have completed and make a dialogue, learning to express the big numbers correctly. The teacher should give the students some time to prepare and then let one pair speak out their dialogue. Sample dialogue: S1: Nowadays, an increasing population is an environmental problem in many countries. Do you know how many babies are born every minute? S2: Every minute two hundred and fifty-nine babies are born. S1: That makes one hundred and thirty-six million, one hundred and thirty thousand, four hundred babies every year. S2: You are right. And do you know what the population of China is? S1: It’s about one billion, three hundred million. It’s about 20 percent of the world’s population. S2: That is to say, the population of the world is about six billion, five million. S1: So many people! Reading In this procedure, students should open their books on page 88, read the dialogue in Activity 3 carefully and try to guess the meanings of the words which they don’t understand according to the context. Students should learn the key phrases and structures in the dialogue. T: Open your books and turn to page 88, read the dialogue in Activity 3, please find out the new words and the phrases in Everyday English in the dialogue. Students should read the dialogue individually. S3: What’s next for…? S4: How about this? S5: It was OK. S6: No idea! S7: I don’t believe it! T: Right. Very good! T: Please read the dialogue again, discuss in groups of four to guess the meaning of them. After a few minutes, check with the whole class. T: Everyone should pay much attention to the difference between “too much’ and “too many”. First find out the sentences with the two phrases in the dialogue. S1: There are too many people and there is not enough space. S2: There is too much traffic, noise and pollution. T: Good! Can you say out the differences of the two phrases? S1: The two phrases are used to modify nouns. The nouns after “too many” are countable nouns, but the nouns after “too much” are uncountable nouns. T: Right! Would you please give me some examples? S2: There are too many books in my study. There is too much rain this year. S3: There are too many rules in our school. We have too much homework every day. T: Very good! Next, read this dialogue aloud in groups of four, please exchange the roles each time. I’ll give you several minutes. Please try your best to remember the details in the dialogue as much as you can, and complete Activity 5. Check the answer with the whole class. Step Ⅳ Pronunciation and speaking In this procedure, students should listen and repeat. The teacher corrects the pronunciation mistakes. T: This activity focuses on reading numbers. Listen to the tape carefully. Play the recording once without stopping. Play the recording again and stop at the end of each number. Ask the whole class to repeat. Ask the students to practise reading numbers in pairs. Read the following numbers. 1. 5,432 five thousand, four hundred and thirty-two 2. 78,610 seventy-eight thousand, six hundred and ten 3. 222,125 two hundred and twenty-two thousand, one hundred and twenty-five 4. 6,320,000 six million, three hundred and twenty thousand 5. 30, 750,800 thirty million, seven hundred and fifty thousand, eight hundred 6. 100,215,500 one hundred million, two hundred and fifteen thousand, five hundred T: In Activity 8, there are some statements. Please check the statements you agree with. Now work in small groups and discuss your answers. Sample answers: S1: I don’t think people should have too many babies. S2: Why do you think so? S1: It’s a big problem to educate too many babies. If people have too many babies, their work will be influenced. If people have too many babies, they will have to make great efforts to make more money to support the family. If people have too many babies, each of the babies can’t get enough care and education from their parents. S2: What you said is reasonable. It’s a fact that there are two many people in the world. S1: I agree with you. You can see too many people everywhere, in the supermarket, in the park, in the street, on the bus and so on. S2: The world’s population is growing faster and faster. A U report says that the population has passed six billion by the end of the twentieth century. People say that by the year 2010, it may be seven billion. StepⅥ Homework 1.

There is no enough space T: 259 babies are born in the world in just one minute. That means people have to find food for over 370,000 mouths one day. The population problem may be the greatest one of the world today. The world’s population is growing faster and faster. In 1990, the number was over five billion. A U report says that the population has passed six billion by the end of the twentieth century. People say that by the year 2010, it may be seven billion.

Teaching resources 教学资源库 I. Some information about population problem in China. Population has always been a big problem for China. What disturbs us more is the result of the Fifth National Population Census, which reports that the ratio of male babies to female babies in the last few years has reached 116.9 to 100, by far higher than the internationally accepted ratio of 107 to 100. It is not difficult to think out the causes for this alarming imbalance between the male population and the female population. China has a long history of showing preference of boys to girls because only boys are believed to continue their family line. Under the pressure of the one-child–for-one–family policy, many people turn to medical devices to identify the sex of their prenatal baby. If it happens to be female, they will think of abortion. Some people may go so far as to take some medicine to ensure that they give birth to a male baby. Still some people are so inhuman as to kill their newly born baby girls. Consequently, the registered birth of boys is unnaturally higher. This marked imbalance will surely bring about some serious social problems. For example, in another 20 years, many men would have to be wifeless, and this will threaten the overall social stability. In this line of thought, I think the government should work out strict laws to protect women by opening more opportunities for them and punish the medical malpractice II. The World’s Population Problem. It’s reported that the world's population was 6 billion in the year 2000, and it is growing faster and faster．Population growth is the world’s greatest problem，because it brings with it a lot of other problems including a lack of food and water，more pollution and not enough jobs．These problems are mostly seen in the developing world as this is where four-fifths of the world’s population live．This is why China，the largest developing country，has a “one couple，one child” policy． 目前世界上人口最多的5个国家依次为：中国(13亿)、印度(11亿)、美国(2.97亿)、印尼(2.23亿)和巴西(1.81亿)。 据美国科普杂志《生活科学》网站24日援引美国人口普查局的预测说，全球人口将于美国东部时间25日晚7时16分（北京时间26日上午8时16分）达到65亿。 美国人口普查局下属国际项目中心的一份研究做出以上预测。研究报告还预计，2012年美国东部时间10月18日下午4时36分，全球人口将达到70亿。 美国人口普查局曾于2004年3月发布报告，指出世界人口在1999年6月达到60亿。而如今，「世界人口是20世纪初的3.5倍有余，几乎是1960年数字的两倍」。 报告指出，更为惊人的是，世界人口从50亿增长到60亿，只花了十余年时间，这比之前任何一个十亿倍数人口增长的速度都要快。通俗地说，这世界上平均每秒钟就有4.4个人出生 Ⅲ 大数词的读法和用法: (1) 基数词的读法与写法 个位和十位之间加连字符“—”，个位或十位与前面的数词之间and；每隔三位加一个单位数词，从后向前数，分别为thousand(千)，million（百万）, billion（十亿），每个单位数词之间加一个分节号，但也可不加。 36：thirty-six 136: one hundred and thirty-six 6136: six thousand, one hundred and thirty-six 36136: thirty-six thousand, one hundred and thirty-six 136136: one hundred and thirty-six thousand, one hundred and thirty-six 136136136: one hundred and thirty-six million, one hundred and thirty-six thousand, one hundred and thirty-six (2) hundred, thousand, million, billion的用法 a) 当hundred, thousand, million, billion 前面有基数词表示具体的数量或与several, some, many 等连用时这几个词本身要用单数形式。例如： Five hundred students in this school. several million many thousand b) 当表示笼统、不具体的数量时，用复数，其后加介词“of”。 hundreds of students millions of animals Ⅳ. The usage of the word “population” population是一个集合名词, 没有复数形式，当它做主语，表示整体概念时其后的谓语动词用单数。如表示个体概念，即人口的百分之几，几分之几做主语时，其后的谓语动词用复数。下面谈一下它的用法。 1、 population常与定冠词the连用,做主语用时,谓语动词常用第三人称单数形 式。例如: The world’s population is increasing faster and faster. At the beginning of the twentieth century, the world’s population was about 1,700 million. 二、当主语是表示“人口的百分之几、几分之几”时,谓语动词用复数形式。 例如: About seventy percent of the population in China are farmers. 三、有时population可用作可数名词，其前可用不定冠词。例如: China has a population of about 1.3 billion. (=There is a population of about 1.3 billion in China.) New York is a big city with a population of over 10 million. 在表示多个地区的人口时，population要用复数形式populations。例如: Many parts of the world, which once had large populations and produced plenty of crops, have become deserts. 四、表示人口“多或少”，不用“much或little”,而要用“large或small”。例如: India has a large population. Singapore has a small population. 五、询问某国、某地有多少人口时，不用“How much...?”,而用“How large...?”;在问具体人口时用“What...?”。例如: ---How large is the population of your hometown? ---The population of our hometown is nearly twice as large as that of yours. ---What is the population of Canada? ---The population of Canada is about 29 million. 六、population还表示“某地、某类的动、植物或物品的总数”。例如: In India, however, the population of tigers has increased, from 2,000 in 1972 to about 5,000 in 1989. Ⅴ 阅读理解 Many of the world’s pollution problems have been caused by the crowding of large groups of people into cities. Supply for the needs of the people leads to further pollution industry. If the rapid increase in human population continues at the present rate, there may be greater harm. Some scientists speak of the increase in number of people as “population pollution”. About 2000 years ago, the world’s population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2000. If the population continues to grow at the same rate, there would be 23 billion people in the world a hundred years from now. Man has been using the earth’s resources more and more rapidly over the years. Some of them are almost gone. Now many people believe that man’s greatest problem is how to control the growth of the population. The materials in the world will not support the human population in time to come, if the present rate of increase continues. Already there is overcrowding in the cities and hunger in some countries. Can man’s rate of increase continue? Many people believe that human survival in the future depends on the answer to the question. 1. “Population pollution” means_________________.
