    A "talking kitchen" teaches students how to cook French and speak French. Researchers at Newcastle University in the United Kingdom have developed the French Digital(数字的) Kitchen. Professor Paul Seedhouse led the project.

    "It works like a satellite navigation(导航) system in a car. The system can tell whether you've done what you were asked to do or not. For example, the sensor(传感器) in the knife not only knows that the knife is moving, but it also knows how the knife is moving. So it can discover whether the knife is slicing (切), whether it's scraping (刮) or what. And so it doesn't go on to the next stage of the program unless you've done what it senses(感到)you should have done," said Paul Seedhouse.

    Students can ask the computer to repeat the instructions or translate them into English. There are vocabulary(词汇) lessons before and after the cooking.

    Professor Seedhouse became interested in the idea after he visited a talking kitchen designed for a different purpose. In his opinion the French Digital Kitchen turns the process (过程) of learning language into a real life experience. "Here you're taking it out of the classroom and you're actually using the language to produce something which you can eat at the end of it. It's very enjoyable," he said.

    The system will be available for sale by the end of 2020. Adding the technology to a new kitchen could add about ten to twenty percent to the building costs. The system could also be added to an existing(现存的) kitchen.

    The researchers are also developing a new digital(的呼吸法) kitchen system that is easy to carry or to move. And the European Union has given them money to begin programs in six other languages, including English, Italian and Spanish.

    A new camera made by a company named Netatmo has facial recognition software (人脸识别系统) that can tell parents at work that their children have returned from school, or that a package (包裹) has been taken to their home. It can also tell them if a stranger has entered their home.

    Janina Mattausch is a product marketing manager for Netatmo.

    "The common security (安全) cameras at present are not that smart. So, they can tell you if something is moving but they don't necessarily know if it's a human being or, ah, if it's your kid- they don't know the difference, so they will warn (警告) you all the time."

    When family members enter a home, the new camera "recognizes" (识别) them and sends information to the owner's smartphone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send the owner a warning that will cause an alarm to sound on the owner's smartphone.

    That is what happened recently to a smart home camera owner named Damien. He lives in Paris.

    "On a Friday I was at work, attending a big monthly meeting when my phone warned. At first I told myself 'Oh, it must be a mistake, maybe I have to set the system again.' —but the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize."

    He watched the video and was very surprised by what he saw.

    "I saw a person I did not know with his shoes on. I was watching it live on video. So I felt totally unbelievable, frozen. I asked a workmate to take me back home as fast as possible and I called the police on the way."

    With the help of the video, the police found the intruder (闯入者) later that day.

The Vine That Ate the South

    Kudzu is a fast-growing vine(蔓生植物) that covers a large area in the southern United States. It is so common that one might think it is a native plant, but it is not. Kudzu was brought to the United States from Japan in 1876. Many Americans thought it was beautiful, and they began to plant it. They didn't know it could grow up to a foot a day during the summer months. Nor did they know it would grow up and over anything in its path.

    In Japan, kudzu experienced cold winters and a short growing season. But in the United States, it has a very long growing season with warm and wet southern weather. It is fine weather for the vine to grow fast.

    In the 1920s, people used the vine to feed farm animals. Ten years later, the government supported to plant kudzu because it kept soil from washing away. However, by the 1950s, the government no longer wanted people to plant the vine. Twenty years after that, the government said it was a harmful plant.

    The vine grows up trees and buildings, making some beautiful shapes. However, trees die after kudzu covers them because they cannot get enough light. Scientists are looking for ways to kill the vine. They used poisons(毒药) to kill the vine. However, some of the poisons made it grow even better. Scientists also find it difficult to dig up Kudzu. The plant is really tough.

    Because kudzu is so hard to kill, some people are making the best of it. So they try to find different uses for the vine. They find the vine can be used to make paper and baskets, it can be used to feed the goats, and it can even be eaten by people. Scientists are studying it in the hope that the vine can be used as a medicine. At the very least, kudzu serves as an example of the unexpected results that can come from non-native plants.
