Passage 1
AI Helps Promote Material Science
Artificial Intelligence (AI) could help promote the development of material science
and accelerate the invention of new materials, according to Chinese experts.
Many core technologies that need breakthroughs in China are related to material
science, and AI could help in these areas. Traditional methods for material
composition analysis are time-consuming and expensive. It takes an average of 10
years for a laboratory to develop new materials and 20 years for mass production.
With AI technology, the development and application cycle of new materials is
expected to be shortened by more than half.
Wang Weihua from the Institute of Physics under CAS said AI is changing the way
new materials are discovered. Through machine learning of material data, AI could
outperform many material scientists and make a more efficient prediction of new
materials.

technology for paraplegics. Patients wearing VR headsets tasked to move through a
playground as a soccer player were able to regain some brain functions. Of the eight
patients tested, each regained some control and four were getting better from full
paraplegics to partial paraplegics.
To help children and teens with autism develop social skills
Professors at the University of Texas in Dallas have created a program that uses
virtual reality to help children with autism develop social skills. Putting kids, teens
and young adults in social situations, they learn how to act properly. By monitoring
brain waves, professors noticed increased activity in areas connected to social
understanding.

Passage 1
AI Helps Promote Material Science
Artificial Intelligence (AI) could help promote the development of material science and accelerate the invention of new materials, according to Chinese experts.
Many core technologies that need breakthroughs in China are related to material science, and AI could help in these areas. Traditional methods for material composition analysis are time-consuming and expensive. It takes an average of 10 years for a laboratory to develop new materials and 20 years for mass production. With AI technology, the development and application cycle of new materials is expected to be shortened by more than half.
Wang Weihua from the Institute of Physics under CAS said AI is changing the way new materials are discovered. Through machine learning of material data, AI could outperform many material scientists and make a more efficient prediction of new materials.
The fast development of AI also needs support from material science. With emerging intelligent robots, wearable medical devices and IoT systems, future smart sensors will require good sensitivity, flexibility, and stability, which puts new demands on materials.
AI and material science are closely related, and material research could offer a solution for AI-related sensitive components.
65.What can AI help do in material science （ ）
A. Slow down the invention of new materials.
B. Shorten the development cycle of new materials.
C. Make material composition analysis more expensive.
D. Increase the time for mass production of new materials.
66.How long does it take to develop new materials with traditional methods （ ）
A. About 5 years. B. About 10 years.
C. About 20 years. D. About 30 years.
67.What does the underlined word “outperform” mean in Chinese （ ）
A. 不如 B. 胜过 C. 帮助 D. 依赖
68.What do future smart sensors need （ ）
A. Good sensitivity, flexibility and stability.
B. AI technology and material science.
C. Machine learning and data analysis.
D. Wearable medical devices and IoT systems.
69.What is the main idea of the passage （ ）

Passage 2
Amazing Uses of VR
Virtual reality (VR) technology holds a lot of possibilities to change the future for a number of fields, like medicine, business, and so on.
To help paraplegics regain their abilities
A year-long study done by Duke University discovered huge benefits of virtual reality technology for paraplegics. Patients wearing VR headsets tasked to move through a playground as a soccer player were able to regain some brain functions. Of the eight patients tested, each regained some control and four were getting better from full paraplegics to partial paraplegics.
To help children and teens with autism develop social skills
Professors at the University of Texas in Dallas have created a program that uses virtual reality to help children with autism develop social skills. Putting kids, teens and young adults in social situations, they learn how to act properly. By monitoring brain waves, professors noticed increased activity in areas connected to social understanding.
To test car safety
VR gives car engineers the ability to test the safety of cars in a virtual setting before actually putting them into markets. Aside from the building cost, testing in virtual environments is also much safer as it doesn’t put human lives at risk.
