【推荐1】Earlier this year, a three-year-old boy from Guangxi died after     1    （leave）in a car for several hours in the hot afternoon sun.     2     this was a horrible tragedy, it isn’t a rare story across the world.

In the United States alone, at least 39 children     3    （die）in similar incidents so far this year, according to the figures published by independent organization NoHeatStroke. But could a high-tech device save a child     4     is locked in a car or help other people take the kid out before it’s too late?

Three high school students at Guangdong Experimental High School may have the answer to this question. They made a device using a sensor     5    （monitor）both the temperature and level of carbon dioxide in a car, which also blows out cool air     6     the levels become too high. The invention, which ensures the safety of passengers in cars, helped them win the gold medal at the 2017 Invention & New Product Exposition, an invention show in the United States.

While the device     7     didn’t sound very complex, it needed special skills to make it. Thanks to on-campus science and technology courses at their school, the students armed themselves with the knowledge     8    （need）to get the job done. They also spent their spare time     9    （research）on the internet and using smart phone apps.

The team stood out not only because of the advanced technology they used, but because of the human interest side of their invention, they noticed some social problems,     10    （think）about them and tried to solve them.

Food waste is one of the greatest challenges of our time, and fruit and vegetables are especially problematic, as about 52% of them go bad before     1    （eventual） reaching consumers. But one Malaysian company has come up     2     a simple solution(解决方案)to this problem — a tiny sticker that keeps fruit from     3     (go) bad for up to weeks.

You've probably seen stickers on fruit before,     4     not like the ones created by the Malaysian company. Those common stickers are typically     5     (use) only to provide consumers with     6     (inform) about the growers and how the fruit was grown, but Stixfresh has a completely different purpose. It contains something special and all-natural that slows down the ripening(成熟)process, keeping the fruit fresh and juicy for much     7    (long).

Stixfresh founder Zhafri Zainudin says that he thought of the idea for the stickers after visiting a friend     8     ran a fruit store. The man was worried about losing money every day because of bad fruit, but he knew that there was no way to stop nature from taking     9     (it) course. The Malaysian businessman worked with many     10     (university) to develop and test his sticker.

At first, Stixfresh stickers were only used to lengthen the shelf-life of mangoes, but the company later worked on other fruit, like dragon fruit, star fruit, apples and pears.

A Chinese company says it has created a new facial recognition system that can identify people even if they     1     (wear) masks. Engineers at Hanwang Technology Ltd. say their system is the first to be created to     2     (effective) identify people wearing face masks.

Hanwang is now selling two main     3     (kind) of products that use the new technology. One performs “single channel” recognition, which is designed to be used at the     4     (enter) to buildings. The other product is a “multi-channel” recognition system, which can identify individuals in     5     crowd of up to 30 people “within a second” by     6     (use) groups of surveillance (监控) cameras. When people wear a mask, the recognition rate can reach about 95%. And the system’s success rate for people not wearing a mask     7     (be) about 99. 5%.

    8     was not immediately clear how Chinese citizens were reacting to the new technology. The Chinese government has already been using other surveillance tools in the fight against the new coronavirus (新冠肺炎).     9     some citizens have expressed opposition to such tools, many others seem to have accepted the methods as a way     10     (deal) with the current health emergency.

In the near future, we will be living in smart homes, which will ensure our     1     (secure), save us energy and provide a more comfortable environment to live in. 

In the smart homes,     2     (use) advanced technology daily for automatic control of everything will be common. Our future home will use integrated sensors to tell when we leave home and then go into an energy⁃efficient mode all by     3     (it). We don’t have to think about turning     4     (switch) on and off ourselves. Our future home will prepare everything for us when we get home every evening. It is also amazing that all controls will respond     5     voice commands. 

Smart homes can help monitor our health. They will give us suggestions on a healthier diet and how     6     (sleep) better. They can also warn us early on if we have a critical illness and     7     (potential) save our lives. In addition, they can help to prevent serious damage from accidents. For instance, if a water pipe     8     (start) leaking, our smart home will detect it. 

This smart technology isn’t     9     daydream or fantasy any longer. Many new innovations have become a reality. Nevertheless, it will take a few years     10     most new homes start to use this new technology.

In the not-too-distant future, we will be living in smart homes. These smart homes will ensure our     1     (secure), save us energy, and provide a more comfortable environment to live in. We will be using advanced technology every day — for    2     (automation) control of just about everything in our home. The future home will use integrated sensors     3     (tell) when you leave home each morning, and then go into an energy-efficient mode all by    4     (it). Your home will also learn your daily routine and     5     (prefer), so everything will be ready for you when you get home each evening. All controls will respond     6     voice commands, so if you want to change your routine, you just say aloud     7     you want and the home system will obey. In addition, the smart home     8     (programme) to monitor your health every day. Smart homes will be able to prevent serious damage from accidents. If there is     9     short in the electrical wiring, your smart home will detect it and provide you with the relevant information. This way, you will be able to fix the problem before your home becomes flooded     10     catches fire.

In the near future, we will be living in smart homes, which will ensure our    1    (safe), save us energy and provide a more comfortable environment to live in.

In the smart homes,    2    (use) advanced technology daily for automatic control of everything will be common. Our future home will use integrated sensors to tell when we leave home and then go into an energy-efficient mode all by     3    (it).

We will find our dinner already    4    ( prepare) without turning switchs on and off ourselves. It is also amazing    5    all controls will respond to voice commands.

Smart homes can help to keep serious damage from    6    (accident). For instance, if a water pipe    7    (start) leaking, our smart home will detect it. In addition, they can help monitor our health. They can also warn us early on if we have a critical sickness and    8    (potential) save our lives.

This smart technology isn’t    9    daydream or fantasy any longer. Many new innovations have become a reality. Nevertheless, it will take a few years    10    most new homes start to use this new technology.
