We've been on an educational journey through Unit 5 Working the Land. Now, it's time for our “Assessing Your Progress” session. This is a great opportunity for us to see how much we've learned and to identify areas where we can still grow. So, are you all ready to take a closer look at your progress? Students: Yes, teacher! Teacher: Wonderful. Let's kick things off with vocabulary. Throughout this unit, we've encountered a rich set of words related to farming. Who can start by naming some of the key farming - related words we learned? Sarah, you go first. Sarah: Pesticide and fertiliser. Teacher: Excellent, Sarah. “Pesticide” is that chemical we use to get rid of pests, and “fertiliser” helps our plants grow better. Can someone else add to the list? Tom: Irrigation and cultivation. Teacher: Very good, Tom. “Irrigation” is about providing water to the fields, and “cultivation” is the process of preparing and using the land for growing crops. Now, let's test your understanding a bit further. I'll describe a word, and you tell me what it is. This word refers to the practice of growing different crops in the same field in different seasons to maintain soil fertility. What word am I thinking of? Emma: Crop rotation? Teacher: Spot - on, Emma! Crop rotation is an important concept in sustainable farming. Now, let's move on to using these words in sentences. I want you to create a sentence using the word “pesticide”. David, you give it a try. David: Farmers use pesticides carefully to protect their crops from harmful insects. Teacher: Great job, David. Your sentence is not only grammatically correct but also uses the word in a contextually appropriate way. Now, someone else, make a sentence with “fertiliser”. Lily: Adding the right amount of fertiliser to the soil is crucial for a good harvest. Teacher: Well - done, Lily. You've grasped the usage well. Now, let's shift our focus to grammar. In this unit, we've dealt with various grammar points. One of them is the use of relative clauses. Remember, relative clauses help us provide more information about a person, thing, or situation. Let's look at an example from our text: “The crops that are grown using organic methods are considered healthier.” Here, the relative clause “that are grown using organic methods” describes “the crops”. Can someone tell me what type of relative clause this is? Is it defining or non - defining? Jack: It's a defining relative clause because it tells us which specific crops are being talked about. Teacher: Absolutely right, Jack. Defining relative clauses are essential for identifying the noun we are referring to. Now, let's practice creating some relative clauses. I'll give you a noun, and you create a relative clause to describe it. The noun is “farmer”. Who can start? Sally: A farmer who uses modern and sustainable farming techniques is more likely to succeed. Teacher: Superb, Sally. Your relative clause clearly defines the type of farmer. Now, let's move on to another grammar point - the present perfect tense. We've seen in the text sentences like “Chemical pesticides and artificial fertilisers have been in widespread use in farming since the middle of the 20th century.” Can anyone explain why the present perfect tense is used here? Mike: Because the action of using chemical pesticides and fertilisers started in the past (the middle of the 20th century) and is still happening now. Teacher: Exactly, Mike. The present perfect tense is used to show an action that began in the past and continues up to the present. Now, I want you to make a sentence using the present perfect tense related to farming. Lucy: Many farmers have switched to organic farming in recent years. Teacher: Well - constructed, Lucy. Your sentence effectively uses the present perfect tense to describe a change that has occurred over time in the farming community. Teacher: Now, let's move on to reading comprehension. We've read passages about chemical and organic farming. I have a few questions to test your understanding. In the text, what were the initial advantages of chemical farming? Tom: Chemical pesticides and fertilisers were seen as a great way to fight crop disease and increase production. Teacher: Correct, Tom. And later on, what problems did scientists discover with the long - term use of chemical farming methods? Emma: Their long - term use can harm both the land and people's health. Pesticides can kill helpful bacteria and insects, and the chemicals can stay in the soil and water, affecting crops, animals, and humans. Teacher: Very good, Emma. You've summarised the key points accurately. Now, let's think about the organic farming part. What are some of the natural methods organic farmers use to keep their soil rich and free of disease? Lily: They use natural waste from animals as fertiliser and change the kind of crop grown in each field every year. Teacher: Right, Lily. These methods help maintain the balance of the soil and avoid the use of harmful chemicals. Now, I'm going to give you a short new passage related to farming, and I want you to read it silently and then answer some questions about it. (Students read the passage silently) Teacher: Okay, here's the first question. What is the main idea of the passage? David: The passage is mainly about a new farming technology that helps reduce water usage in agriculture. Teacher: Good job, David. Now, for the second question, according to the passage, what are the benefits of this new technology? Sarah: It helps save water and also improves the quality of the crops. Teacher: Well - answered, Sarah. Reading comprehension is an important skill, and by practicing like this, you're getting better at understanding different types of texts related to our unit topic. Teacher: Next, we come to writing. In this unit, we've learned about different aspects of farming, and now it's your turn to show what you've learned through writing. I want you to write a short paragraph comparing chemical and organic farming. You can start by stating the main differences between the two, and then briefly mention their advantages and disadvantages. You can use the vocabulary and grammar we've discussed. Start writing now, and I'll come around to check on your progress. (Students start writing) Teacher: (Going around the class, providing individual feedback) This is looking good, Tom. You've clearly stated the differences. Just make sure to use some relative clauses to add more detail. Sally, your use of vocabulary is great, but check your sentence structure in this part. Teacher: Okay, let's stop here. Who would like to share their paragraph with the class? Emma: Chemical farming uses pesticides and artificial fertilisers, which can increase production quickly. However, it may harm the environment and people's health in the long run. On the other hand, organic farming, which relies on natural methods like using animal waste as fertiliser, is better for the environment and produces healthier food. But it might have a lower yield sometimes. Teacher: Excellent, Emma. Your paragraph is well - structured. You've effectively compared the two farming methods using relative clauses and appropriate vocabulary. Now, let's have one more student share. Jack: Chemical farming, which has been widely used since the 20th century, is good for fighting crop diseases and getting high yields. But it has many drawbacks, such as polluting the soil and water. Organic farming, on the contrary, is a more sustainable option as it keeps the environment clean. But it requires more knowledge and effort from farmers. Teacher: Well - done, Jack. You've also done a great job of presenting the comparison. After hearing these examples, if you have time, you can go back and make some improvements to your own paragraphs. Teacher: Now, let's talk about listening. I'm going to play a short audio clip. It's an interview with a farmer. While you listen, try to answer these questions: What type of farming does the farmer practice? What challenges does he face? (Plays the audio clip) Teacher: Okay, let's start with the first question. What type of farming does the farmer practice? Lucy: He practices organic farming. Teacher: Correct, Lucy. And what challenges does he face? Mike: He says that the cost of organic seeds is high, and it's sometimes difficult to find enough natural fertilisers. Teacher: Well - heard, Mike. Listening is an important part of language learning, and by practicing with different types of audio materials like this, you're improving your ability to understand spoken English, especially in context related to our unit. Teacher: Finally, let's reflect on our learning in this unit. What do you think is the most important thing you've learned about farming? And how do you think this knowledge can be useful in your life or in the future? Let's have a class discussion. Sarah: I learned that organic farming is better for the environment, and maybe in the future, I can choose to buy more organic food to support it. Teacher: That's a great point, Sarah. Choosing organic food can indeed make a small but significant difference. Tom: I learned about the different methods farmers use, and it makes me appreciate the food we eat more. Teacher: Absolutely, Tom. Understanding where our food comes from and how it's produced can really change our perspective. Teacher: In conclusion, through this “Assessing Your Progress” session, I can see that you've all made great progress in your understanding of Unit 5 Working the Land. Keep up the good work, and remember to apply what you've learned in your future English studies and in your daily life. 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
