Passage 1
Water scarcity is a growing problem around the world. According to the United Nations, more than 2 billion people live in countries with water shortages. By 2025, this number is expected to rise to 3.5 billion.
There are several causes of water scarcity. One of the main causes is overpopulation. As the world's population grows, the demand for water increases. Another cause is climate change, which leads to changes in rainfall patterns and more frequent droughts. Water pollution is also a major factor, as it reduces the amount of available clean water.
To address water scarcity, various solutions are being implemented. One solution is water conservation, which involves reducing water waste and using water more efficiently. For example, farmers can use drip irrigation instead of flood irrigation to save water. Another solution is water recycling, which treats wastewater so that it can be reused for non-drinking purposes, such as watering plants and cleaning.
Digital technology is also playing a role in addressing water scarcity. Smart water management systems use sensors and data analytics to monitor water usage and detect leaks. This helps reduce water waste and improve water efficiency. In addition, satellite technology is used to monitor water resources and predict droughts, allowing authorities to take proactive measures.
However, there are also challenges in addressing water scarcity. One challenge is the high cost of implementing water conservation and recycling projects. Another challenge is the lack of awareness among people about the importance of water conservation. In addition, political and economic factors can hinder the implementation of effective water management strategies.
( ) 1. How many people are expected to live in countries with water shortages by 2025
A. 2 billion B. 3.5 billion C. 7 billion D. 10 billion
( ) 2. Which of the following is NOT a cause of water scarcity
A. Overpopulation B. Climate change C. Water pollution D. Water recycling
( ) 3. What is drip irrigation
A. A method of watering plants by flooding the fields.
B. A method of watering plants by using small tubes to deliver water directly to the roots.
C. A method of collecting rainwater for irrigation.
D. A method of treating wastewater for irrigation.
( ) 4. How does digital technology help address water scarcity
A. By reducing the demand for water.
B. By increasing the supply of water.
C. By monitoring water usage and detecting leaks.
D. By changing rainfall patterns.
( ) 5. What is one of the challenges in addressing water scarcity
A. The low cost of water conservation projects.
B. The high level of awareness about water conservation.
C. Political and economic factors.
D. The abundance of water resources.
Passage 2
Digital technology has transformed the way we live, work and communicate. It has brought many benefits, but it also has some negative impacts.
One of the main benefits of digital technology is improved communication. We can now communicate with people around the world instantly through email, social media and video calls. This has made it easier to stay in touch with friends and family and to collaborate with colleagues.
Digital technology has also revolutionized education. Online learning platforms allow students to access educational resources from anywhere in the world. They can take courses, watch lectures and interact with teachers and other students online. This has made education more accessible to people who live in remote areas or who have other commitments.
In addition, digital technology has made our lives more convenient. We can shop online, bank online and pay bills online. We can also use apps to order food, book tickets and navigate our way around cities.
However, digital technology also has some negative impacts. One of the main concerns is cyberbullying. This is when people use digital technology to harass, intimidate or humiliate others. Cyberbullying can have a serious impact on the mental health of victims.
Another concern is privacy issues. Digital technology allows companies and governments to collect large amounts of personal data. This data can be used for various purposes, but it also raises concerns about how it is stored and used.
In addition, excessive use of digital technology can lead to addiction. Many people spend too much time on their smartphones, computers and other digital devices. This can affect their physical and mental health, as well as their relationships with others.
( ) 6. What is one of the main benefits of digital technology
Improved communication B. Cyberbullying
C. Privacy issues D. Addiction
( ) 7. How has digital technology revolutionized education
A. By making education more expensive.
B. By making education less accessible.
C. By allowing students to access educational resources online.
D. By replacing teachers with digital devices.
( ) 8. What is cyberbullying
A. Using digital technology to help others.
B. Using digital technology to harass, intimidate or humiliate others.
C. Using digital technology to learn new skills.
D. Using digital technology to communicate with friends.
( ) 9. What is a concern about personal data
A. It is not collected by companies and governments.
B. It is stored and used properly.
C. It is not accessible to anyone.
D. It is stored and used improperly.
( )10. What can excessive use of digital technology lead to
Improved physical health B. Addiction
