How fast might your mobile phone network be in the future? After 3G and 4G, 5G is on the way. 5G (from “the fifth-generation mobile networks”) is the latest generation of mobile communications, including extreme high bandwidth(寬帶), low latency(低延時(shí)), and high density(高密度) connections. According to Science Daily, 5G tests are expected to start in 2019 in the US and by 2020 in the UK. China has already tested 5G in10 big cities and announced the start of 5G this year.

As a result of the increased size of networks, data transfer will be much faster and more reliable.5G is expected to be 10 to 100 times faster than the average speed of the current 4G network. It may enable many new uses that are impossible on older networks. For example, you can download a film within just 3 seconds. This used to take a few minutes with a 4G network. In addition, there will be enough capacity(容量) for everyone to chat on social media and watch movies on their phones. Scientists say 5G will help the development of self-driving cars and the “5G man-like robot”as well. Most importantly, 5G will help us build the Internet of things(IoT,物聯(lián)網(wǎng)). loT connects everyday devices to the Internet. People can control their devices remotely. For example, on a hot summer’s day, you could tum on your air conditioning with loT before you go home. All of these things need very fast Internet speeds.5G will be the key.

Every single day, our technology seems to shift up a level. Some big companies like Huawei and Samsung have started to deliver. 5G products. 5G technology is becoming reality, It will make some unimagined changes. Let’s wait and see what it brings.

【題目】

As the world's population continues to increase, so does the amount of global waste people produce. According to data collected by the World Bank Group, nations are on pace to produce 4 billion tons of waste every year by 2100. Many experts are calling the problem of global waste a worldwide health crisis（危機(jī)）because it is ruining the world's oceans, air and soil and endangering the health of all living things.

For years, governments have been telling people that living a zero-waste lifestyle is the way to go. One example of this is what's often called the three R's: reduce, reuse recycle. In that case, less money is spent on waste management. Such positive effects on an economy（經(jīng)濟(jì)）as a result of applying the basic rules of reduce, reuse and recycle-is known as a circular economy.

Now some stores are helping people do that. Sometimes, grocery stores produce waste when they throw away food including fruit and vegetables that don't look good any more.In other cases, it's packaged food that is nearing the "sell-by" date printed on the package which is not considered safe to eat. To solve this problem, business people are opening smaller zero-waste stores. Instead of selling food in packages, these stores offer it in open containers. Customers bring their own bags or clean containers to the store. There, they fill their bags or containers with everything from nuts and rice to oil and sauce. They pay for only the amount of each product that they need. Zero-waste stores often sell fruit and vegetables as well. When these goods start to look old, they're sold at a discount or donated to a charity Inspired by these smaller zero-waste stores, some large supermarkets are taking similar steps to reduce the amount of waste that they produce.

By following a circular system, more products than ever are being produced using recycled materials. For example, used tires（輪胎）can be recovered to pave roads, while plastic is reused to make new plastic products. Environmentally-friendly decisions like these help to protect and save natural resources, reduce pollution, save landfill space and even create new job opportunities. Recycling can truly turn garbage into gold.
