《2025年暑假课程练习南方出版社七年级英语》

A
What will the world be like in the future? There are plenty of people who are happy to give their opinions of what we will be doing in 2050. Here are two predictions(预测) about the world of tomorrow.
When we dream about the future, many like to think of owning a personal flying car. The advantages are obvious(明显的). This technology would allow total freedom of movement. We could fly at 480 km per hour, avoiding(避免) traffic lights and busy roads. However, some people believe there will be problems with traffic control. If the cars become popular, there is likely to be an air traffic jam. Another big problem is mechanical(机械的) failure. What will happen if the cars stop working? These are problems we must expect(预期) if flying cars become a reality(现实).
Three-dimensional printing is another new technology with exciting possibilities. 3D printers are used to build an object with liquid plastic. They build the object layer by layer until it is complete. Car companies already use 3D printers to make life-size(与实物一样大小的) models of car parts, and medical companies use the technology to make man-made body parts. As we move into the future, 3D printing will revolutionize(彻底改变) the way we shop, the way we manufacture products and the way we treat sick people. The disadvantage is that such equipment will be extremely expensive.
So in the future, we might be able to fly to work or print out new shoes in our daily life. Although there are some problems to solve before this is possible, we can certainly dream of a world where technology makes life easier and safer for millions of people.
