This payment method is fast and convenient. It also saves us the trouble of carrying large amounts of cash. However, mobile payments also bring some problems. Some people, especially teenagers, may spend too much money because it is so easy to pay. They do not feel that they are losing real money. Also, if a phone is lost or stolen, its owner may lose money. Therefore, we need to be careful and set a daily spending limit. For many families, mobile payments make life easier.

In the 1940s, the first computers were as big as a room. They were very heavy and slow, and only a few scientists could use them. Later, in 1971, a small component called the microchip was invented. This was a big breakthrough. It made computers much smaller and faster. In 1981, the first personal computer (PC) came out. At that time, many experts did not believe that ordinary people would want a computer at home. However, they were wrong. In just two years, thousands of PCs were sold. In the 1990s, smartphones appeared. They are small computers that can connect to the Internet and run many apps. Today, we use them to study, work, shop, and have fun. Scientists are now working on quantum computers（量子计算机）. They will be many times faster than today’s computers. In the future, computers may become even smaller and more powerful. They will continue to change our lives in surprising ways. 1. What were the first computers like in the 1940s? 2. What did the microchip do to computers? 3. Why were experts wrong about the PC? 4.

Digital technology has changed the way we read. Today, many people read e-books on smartphones, tablets, or e-readers. E-books are easy to carry because one small device can hold thousands of books. Readers can also change the font size and read in the dark. This makes them especially useful for people who travel a lot. However, paper books still have many fans. Some readers say that paper books are more comfortable to hold. They like the smell of paper and the feeling of turning pages. Paper books don’t need electricity, so they can be read anywhere. In addition, reading paper books may help people focus better because there are no distractions（分心）from games or messages on digital devices. Which is better? It may depend on the situation. For study and quick reading, e-books are useful. For deep reading and relaxation, paper books may be a better choice. Many people use both.
