You will hear a lecture about how carbon dioxide is produced from food And what are the effects of the emission problem?

First, You have some time to look at questions 31 to 40.

Now listen carefully and answer questions 31 to 40.

Good afternoon.

Thanks for coming to today's lecture.

In the last few decades the environmental impact of food production and consumption has become one of the greatest concerns.

When we look at what we eat and how we produce the food, we can find extensive evidence for how we damage our environment.

Greenhouse gas emissions may come from livestock such as cows, agricultural soils and rice production.

According to statistics, the carbon dioxide emissions from the production of the food people

consume every day are almost the same as the emissions we make when we are driving.

Let's look at some more specific examples.

The cultivation and processing of 100 grams of coffee beans are responsible for 140 grams of carbon dioxide.

Now, some international organizations are training farmers in many countries to

use sustainable agricultural methods as a way of reducing their carbon dioxide emissions.

All agricultural practices have been found to have a variety of effects on the environment.

Some of the environmental effects are associated with meat production.

The popular red meat requires 28 times more land to produce than chicken,

11 times more water and results in 5 times more climate warming emissions.

According to another research, cooking process also causes greenhouse gas emissions.

Scientists now are working on how to best minimize its impact.

Another problem that we cannot neglect is the packaging of food products.

as packaging takes a lot of energy, water and other natural resources to produce.

So a lot of natural resources are wasted.

when we throw the packaging materials away.

Furthermore, Packaging waste produces a big amount of greenhouse gas.

To make things even worse, the food we eat often comes from places far away.

Therefore, the transportation of our food across long distances contributes to air and water pollution.

In recent decades with the growing number of population, more food is in demand.

So more land has been used to produce food.

Hundreds and even thousands of forests have been cut down.

It had a devastating effect on the climate because forests can absorb greenhouse gases.

People in different parts of the world apply various kinds of farming practices.

In most countries, cows and other livestock are kept on the farms, while in some countries they are kept in a restricted area on a mountain,

but they all contribute to the carbon dioxide emissions.

And for animal agriculture, the problem can be more serious because the livestock need food all the time.

In America, cows eat an overwhelming amount of corn and soybeans each year.

In order to create a better world for us and our future generations, we should adopt sustainable agriculture.

The goal of sustainable agriculture is to meet the world's growing demand for food at the present without affecting future generations.

Every person involved in the food system, growers, food processors, distributors, retailers,

consumers and waste managers can play a role in ensuring a sustainable agricultural system.

There are many practices commonly used by people working in sustainable agriculture and sustainable food systems.

Crop growers may change their food production methods to prevent pollution.

Although some other areas of agriculture are very hard to change such as fishing,

Consumers and retailers concerned with sustainability can look for foods that are environmentally friendly.

However, Sustainable agriculture is more than a collection of practices, It is also a process of negotiation.

a push and pull between the competing interests of an individual farmer

or of people in a community as they work to solve complex problems about how we grow our food.

In conclusion, I want to emphasize

that we may not be able to go back to the old times and live a simpler lifestyle,

but we can take an active role in preventing more environmental problems caused by carbon dioxide emissions.

In the next lecture, I will share some of the studies and effective solutions with you.

That is the end of Section 4.

You now have half a minute to check your answers.

That is the end of the listening test.

In the IELTS test, you would now have 10 minutes to transfer your answers to your answer sheet.

FOR YOU

為何用這段影片練習口語？

這段關於食物碳排放的講座是雅思口語練習和shadow speech的優質素材。它涵蓋環境、農業等學術話題，句式嚴謹且貼近生活，能幫助學習者熟悉議論文結構與邏輯表達。通過模仿演講者的語氣和節奏，不僅能提升口語流暢度，還能積累環保領域的實用詞彙，輕鬆應對雅思口語中的社會類話題。

語境中的語法與表達

比較級結構：“紅肉的生產所需土地是雞肉的28倍”，使用“倍數+more...than”句式，清晰表達資料對比，適合在描述差異時使用。
因果邏輯表達：“由於森林能吸收溫室氣體，砍伐森林對氣候造成毀滅性影響”，通過“因為...所以...”的結構強化論證，提升口語的邏輯性。
被動語態：“農民正在接受可持續農業方法的培訓”，被動語態常用於正式演講，使表達更客觀，是英語口語練習中需掌握的重點。

常見發音陷阱

影片中部分詞彙易讀錯，如“livestock”（牲畜）的發音為/ˈlaɪvstɒk/，注意“v”和“s”的連讀；“sustainable”（可持續的）重音在第二音節/səˈsteɪnəbl/，避免讀成/sʌˈsteɪnəbl/。此外，演講者語速適中，適合shadow speak練習，可逐句模仿語調的起伏，提升口語的自然度。

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	is produced · have been found · are associated
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事	has become · have been found · has been

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
