Passage 1
Silk is one of the most famous materials in the world. It has been used for thousands of years. The history of silk began in ancient China. According to legend, the Chinese Empress Leizu discovered silk when a cocoon fell into her tea. She noticed that the cocoon was made of a long, soft thread. This thread could be used to make beautiful fabric.
The Chinese kept the secret of silk production for many years. They did not want other countries to know how to make silk. However, eventually, the secret spread to other parts of the world. Today, silk is produced in many countries, but China is still the largest producer of silk in the world.
Silk is known for its softness and strength. It is used to make clothing, scarves, and even furniture. Silk is also very expensive because it takes a lot of work to produce. Thousands of silkworms are needed to make just one kilogram of silk.

Passage 2
Paper is one of the most important inventions in human history. It was first invented in China over 2,000 years ago. The process of making paper has changed a lot since then, but the basic idea is still the same.
First, raw materials like wood, cotton, or bamboo are collected. These materials are then broken down into small pieces and mixed with water to create a pulp. The pulp is spread out into thin sheets and pressed to remove the water. Finally, the sheets are dried and cut into the desired size.
Today, paper is used for many things, such as writing, printing, and packaging. However, the production of paper can have a negative impact on the environment. Cutting down trees for paper can lead to deforestation, and the chemicals used in the process can pollute water and air.

1. Where was paper first invented
2. What are the raw materials used to make paper
3. What is the first step in the process of making paper
4. What are some uses of paper today

Passage 4
The Impact of Fast Fashion on the Environment
Fast fashion refers to the rapid production of cheap clothing to meet the latest trends. While fast fashion makes clothing more affordable, it has a negative impact on the environment.
The production of fast fashion requires a large amount of water and energy. For example, it takes about 2,700 liters of water to make one cotton T-shirt. In addition, the chemicals used in dyeing and treating fabrics can pollute rivers and oceans.
Another problem is waste. Fast fashion encourages people to buy more clothes than they need. As a result, many clothes are thrown away after being worn only a few times. These clothes often end up in landfills, where they can take hundreds of years to decompose.
To reduce the impact of fast fashion, some people are choosing to buy second-hand clothes or support sustainable fashion brands. These brands use eco-friendly materials and practices to reduce their environmental footprint.
Questions:
1. What is fast fashion
2. How much water is needed to make one cotton T-shirt
3. What are the environmental problems caused by fast fashion
4. Why do many clothes end up in landfills
5. What can people do to reduce the impact of fast fashion

Passage 5
Blue jeans are one of the most popular types of clothing in the world. They were invented by Levi Strauss in the 19th century. At that time, Strauss was a businessman who sold fabric to gold miners in California. The miners needed strong pants that could withstand hard work, so Strauss created pants made from denim fabric.
Denim is a type of cotton fabric that is dyed with indigo to give it a blue color. The fabric is very durable, which makes it perfect for work clothes. Over time, blue jeans became popular not only among workers but also among people of all ages and backgrounds.
Today, blue jeans are a symbol of casual fashion. They are worn by millions of people around the world. However, the production of jeans can have a negative impact on the environment. The dyeing process uses a lot of water and chemicals, which can pollute the environment.

Passage 6
As people become more aware of the environmental impact of fashion, sustainable fashion is becoming more popular. Sustainable fashion refers to clothing that is made in an environmentally friendly way. This includes using organic materials, recycling old clothes, and reducing waste.
One example of sustainable fashion is the use of recycled plastic bottles to make fabric. The plastic is melted down and turned into fibers, which can be used to make clothing. This process helps reduce plastic waste and saves energy.
Another trend in sustainable fashion is the use of natural dyes. Traditional fabric dyes often contain harmful chemicals, but natural dyes are made from plants and other organic materials. These dyes are safer for the environment and for the people who work with them.
While sustainable fashion is still more expensive than fast fashion, many people believe it is worth the cost. By choosing sustainable fashion, we can help protect the environment and support ethical practices in the fashion industry.
Questions:
1. What is sustainable fashion
2. How are recycled plastic bottles used in sustainable fashion
3. What are natural dyes made from
4. Why is sustainable fashion more expensive than fast fashion
