Digital technology has become an important part of our daily lives. We use digital devices and services almost every day, from waking up with a smartphone alarm to going to bed after browsing social media. It's hard to imagine what life 1__ like without digital technology.
In the past, people 2____ letters to keep in touch with friends far away. It usually took weeks or even months to get a reply. But now, with digital tools like email and instant messaging apps, we can communicate with others in seconds. We can also make video calls to see each other's faces, which 3_____ us feel closer even when we are in different countries.
Digital technology also changes the way we learn. In the past, students mainly learned from textbooks and teachers' lectures. Now, we can take online courses, watch educational videos and use digital libraries to get more knowledge. During the pandemic, many schools 4______ online classes to help students keep learning. This shows how useful digital technology is in education.
However, digital life also brings some problems. For example, spending too much time on digital screens 5______ bad for our eyes and health. Some people may also become addicted to online games or social media, which affects their work and study. What's more, our personal information may be at risk when we use digital services. Hackers 6______ steal our information if we don't take safety measures.
To have a healthy digital life, we need to set rules for ourselves. We should limit the time we spend on digital devices every day. We should also learn how to protect our personal information, like not sharing our passwords with others. 7______ important to balance our digital life and real life. We can go outside to play sports or meet friends in person instead of staying at home using digital devices all the time.
Last month, our class 8______ a discussion about “How to Have a Healthy Digital Life”. Many students shared their ideas. Some said they would turn off their phones during family dinners. Others said they would only use social media for a short time every day. We also invited a police officer to give us a talk about digital safety. He told us that we 9______ be careful when making friends online and not click on unknown links.
In the future, digital technology 10______ continue to develop. It will bring more convenience to our lives, but we must also remember to use it wisely. Only in this way can we enjoy the benefits of digital life without being harmed by it.

Digital Payments: Changing Our Shopping Habits
In recent years, digital payments have become more and more popular around the world. From scanning a QR code to using a digital wallet, people are now used to paying for things without cash. This change has greatly affected our shopping habits.
One of the biggest advantages of digital payments is convenience. In the past, we had to carry cash with us when we went shopping. If we forgot our wallet or didn't have enough cash, we couldn't buy what we wanted. But with digital payments, all we need is a smartphone. We can pay for groceries, clothes, tickets and even street food with just a few taps on the screen. This saves us a lot of time and trouble.
Digital payments also make shopping more secure. When we carry cash, there's a risk of losing it or being stolen. But with digital payments, our money is stored in a digital wallet with passwords or fingerprint recognition. Even if our phone is lost, others can't use our digital wallet easily. Some digital payment platforms also offer insurance for unauthorized transactions, which makes us feel safer.
Another benefit of digital payments is that they help us keep track of our spending. Most digital payment apps record every transaction we make. We can check our spending history at any time and know exactly where our money goes. This helps us manage our finances better and avoid overspending.
However, digital payments are not perfect. For example, some elderly people may find it hard to use digital payment tools because they are not familiar with technology. In some remote areas, there may be no network, so digital payments can't be used. Also, there's a risk of cyber-attacks. Hackers may try to steal our money by breaking into our digital wallets or payment accounts.
Despite these problems, digital payments are still changing our shopping habits for the better. They make our lives more convenient and secure. As technology continues to develop, digital payments will become even more popular in the future.

Online Learning: A New Way of Studying
With the development of digital technology, online learning has become a popular way of studying. More and more students are choosing to take online courses instead of attending traditional classes. Online learning has many advantages that make it a good choice for students.
First, online learning is flexible. Students can study at any time and any place as long as they have a digital device and an Internet connection. This is especially helpful for students who have part-time jobs or other responsibilities. For example, a student who works in the evening can study online in the morning. A student who lives in a remote area can take courses from top universities without moving to a big city.
Second, online learning is more affordable. Traditional classes often require students to pay for tuition, textbooks, transportation and accommodation. But online courses usually have lower tuition fees. Students don't need to buy many textbooks because most materials are provided online for free. They also don't need to spend money on transportation or accommodation, which saves them a lot of money.
Third, online learning offers a variety of courses. Students can choose from thousands of online courses on different subjects, from languages to science and technology. They can even take courses from foreign universities and learn from famous professors. This helps students expand their knowledge and learn things that may not be available in their local schools.
However, online learning also has some challenges. One of the biggest challenges is that it requires students to have self-discipline. Without a teacher to监督 (supervise) them, some students may procrastinate (拖延) and not finish their courses on time. Another challenge is that students may feel lonely because they don't have face-to-face communication with their classmates and teachers. They may also have trouble getting help when they don't understand a topic.
Despite these challenges, online learning is still a great way of studying. It provides students with more choices and flexibility. As digital technology continues to improve, online learning will become even better and help more students achieve their educational goals.
( )1. What is one of the advantages of online learning
A. It requires students to attend classes at fixed times.
B. It is flexible.
C. It is more expensive than traditional classes.
D. It only offers a few courses.

A. It has higher tuition fees.
B. Students need to buy many textbooks.
C. Students don't need to pay for transportation or accommodation.
D. It requires students to live in a big city.
( )3. What is a big challenge of online learning
