In the realm of modern technology, virtual reality (VR) and augmented reality (AR) are no longer just concepts from science fiction. VR immerses users in a completely artificial environment, while AR overlays digital information onto the real world.
One of the most significant applications of VR is in the field of gaming. Gamers can now step into a virtual world, interact with the environment, and feel a sense of presence like never before. For example, in a VR horror game, players can physically turn around to face approaching threats, heightening the fear factor.
AR, on the other hand, has found its way into various aspects of daily life. Mobile apps using AR technology can provide real - time information about historical sites when you point your phone at them. It can also be used in interior design, allowing users to visualize how furniture would look in their living spaces before making a purchase.
However, the development of VR and AR also faces challenges. Technical limitations such as high - cost hardware and motion sickness in VR are still issues. Moreover, privacy concerns arise as these technologies collect data about users' movements and interactions.
What is the main difference between VR and AR?
A. VR is used in gaming, while AR is used in daily life.
B. VR creates a completely artificial environment, and AR adds digital information to the real world.
C. VR is more expensive than AR.
D. VR has more privacy concerns than AR.
Why is VR popular in gaming?
A. It allows gamers to play with others from all over the world.
B. It provides a more immersive and realistic gaming experience.
C. It has lower - cost hardware.
D. It doesn't cause motion sickness.
What are the challenges of VR and AR development?

The concept of sustainable fashion has been gaining momentum in recent years. Sustainable fashion focuses on reducing the environmental and social impact of the fashion industry.
One aspect of sustainable fashion is the use of eco - friendly materials. For example, organic cotton, which is grown without the use of harmful pesticides and fertilizers, is a popular choice. Recycled materials are also widely used. Brands are now creating clothing from recycled plastic bottles, reducing waste and the need for new raw materials.
Another important factor is ethical production. This means ensuring fair wages and good working conditions for garment workers. Many sustainable fashion brands are transparent about their production processes, allowing consumers to know where and how their clothes are made.
However, sustainable fashion also faces obstacles. The higher cost of eco - friendly materials and ethical production often leads to higher - priced products, making them less accessible to some consumers. There is also a lack of consumer awareness about the importance of sustainable fashion.
What is the main idea of sustainable fashion?
A. To produce more fashionable clothes.
B. To reduce the environmental and social impact of the fashion industry.
C. To use more expensive materials.
D. To increase the profit of the fashion industry.
What are eco - friendly materials?
A. Materials that are expensive.
B. Materials that are harmful to the environment.

Artificial intelligence (AI) has made remarkable progress in natural language processing. AI - powered language models can now generate human - like text, answer questions, and even translate languages.
One of the most well - known language models is GPT - 3. It can produce text on a wide range of topics, from writing stories to providing technical explanations. For instance, it can create a fictional story based on a simple prompt like “Write a story about a magical forest.”
These language models use deep learning algorithms to analyze vast amounts of text data. They learn grammar, vocabulary, and semantic relationships from the data, enabling them to generate relevant and coherent text.
However, there are concerns about AI - generated text. There are issues of misinformation, as AI may generate false or misleading content. There are also ethical questions regarding the use of AI - generated text, such as plagiarism and the authenticity of the information.
What can AI - powered language models do?
A. Only generate text.
B. Generate text, answer questions, and translate languages.
C. Only answer questions.
D. Only translate languages.
How do language models work?

I had always been interested in photography, but I never had the 1 (courage/time/energy/money) to take a professional course. So, when I heard about a free online photography course, I was 2 (hesitant/excited/worried/confused).
The course was 3 (organized/holding/conducted/held) by a famous photographer. The first few lessons were about the 4 (history/usage/function/structure) of cameras and basic photography techniques. I found them a bit 5 (boring/interesting/confusing/exciting) at first, but as I delved deeper, I began to understand their importance.
One of the most challenging parts was learning to 6 (control/operate/handle/manage) the camera settings. There were so many 7 (buttons/functions/parameters/settings) to adjust, such as aperture, shutter speed, and ISO. But with practice, I gradually got the 8 (hang/way/key/skill) of it.
During the course, we were given weekly 9 (tasks/jobs/works/duties) to apply what we had learned. One week, we had to take pictures of 10 (nature/natural/naturally/nature's) scenes. I spent hours exploring different locations to find the perfect shot.
The feedback from the instructor was 11 (valuable/worthless/expensive/cheap). He pointed out our mistakes and gave us 12 (useless/helpful/harmful/meaningless) suggestions on how to improve.
As the course 13 (went/continued/advanced/progressed), I became more confident in my skills. I started to see the world 14 (in/from/with/through) a different perspective, noticing details that I had never paid attention to before.
In the end, I was able to 15 (produce/create/make/generate) some really good photos, and I even won a small 16 (prize/award/reward/trophy) in a local photography competition. This course not only 17 (developed/improved/raised/boosted) my photography skills but also 18 (changed/transformed/altered/modified) my way of looking at the world. It was truly a 19 (life - changing/life - long/life - saving/life - giving) experience, and I would always be 20 (grateful/thankful/indebted/appreciative) for it.
