（2022·广东东莞·东莞市横沥中学校考一模）If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the generation of your mobile network. But these symbols will become things of the past after 5G fully arrives.

On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate Ⅹ smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

Now, 4G takes about 100 to 200 milliseconds(毫秒) to send and receive data(数据). But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster. It can be used in many other ways as well.

For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-lag. When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash(撞击) because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, according to CNN.

5G could also be used to power the Internet of Things(IoT), a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IoT under 5G, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.

All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.

（2023春·广东佛山·九年级统考一模）There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of age, some people need to sleep more while for some a few hours is enough.

When you sleep less. You are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to pay back the hours on your sleep credit card.”

For those who value work more than sleep they should listen to what a famous person once said, “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”

（2023春·广东茂名·九年级统考一模）Chinese buyers used to prize foreign brands, thinking that products made by American or European companies are of higher quality（质量）than Chinese ones. Increasingly, that’s no longer the case.

Chinese people born before 1985 generally think that foreign brands are better than Chinese ones, billionaire William Li told Business Insider during a recent interview on CCTV 9. But for who were born after 1985, it is a different picture.

“When I first went to the United Kingdom in 1997, I thought that the difference between China and Europe was quite big,” Li said. “But for those born in the 1990s, when they visit Europe or the US, they do not think there is a big difference.”

The change in thinking among Chinese buyers is showing up in many markets in China where western companies used to control. A study by Credit Suisse published in March found that young Chinese buyers are increasingly showing a home brand bias.

More than 90% of young Chinese buyers would prefer to buy home appliance brands, according to the study. Meanwhile, home companies producing food, drinks, or personal care products increased their share of the market by 3.3% over the last ten years to nearly 70%.

“Chinese buyers, especially the younger ones, don’t just believe that foreign brands are better. Right now, Chinese buyers think China is good and ‘Made in China’ is not bad at all.” Charlie Chen, head of China buyer research at Credit Suisse, told South China Morning Post in March.

The Chinese smartphone market is controlled by home companies—Huawei, Oppo, Vivo, and Xiaomi. Apple is the only foreign brand in the top five, but it has lost large ground to the home brands in recent years. Its
