①Mobile phones have changed a lot in recent years. They actually become more than tools for making calls. Let's look at how they've changed our lives.
②In the early days, mobile phones were very different from what we use today. The first cellphone in 1973 was as big as a brick (砖) and weighed over 1 kilogram. It could only work for 30 minutes after 10 hours of charging (充电)! By the 1980s, mobile phones became smaller but still cost 4,000, as much as a car. They were so expensive that only rich people could afford them. It was a symbol of a high status (身份). Big changes happened in the 1990s. Smartphones became cheaper and more people could buy them. The Nokia 1011 was one of the most popular models. Then in the early 2000s, phones got even smarter. Some could take photos, others had touch screens, and a type of phone even had a full keyboard for email. The biggest change came in 2007 when Apple introduced the iPhone. This was the first kind of phone that worked like a small computer. Its touch screen and special design made it very popular. Soon after, the App Store allowed people to download many useful apps.
③In the past 10 years, smartphones have become even more powerful. Now they can play high-quality videos and games that look almost like real life. Their cameras take photos as well as professional cameras did in the past. People don't need to carry cash anymore because
phones can pay for things. They also replace many other tools like maps, calculators (计算器) and flashlights.
④At the same time, Chinese brands like Huawei, Xiaomi, vivo and OPPO have become the leaders in phone technology among the world. Today's phones are much faster than those from 10 years ago, with much better cameras and batteries.
⑤From heavy "bricks" to slim smart-phones, mobile phones have changed beyond recognition. As technology keeps improving, who knows what amazing changes will come next?
