铲屎官的福音！带「猫脸识别」功能的智能宠物门上线！
Installing a little door in, well, your main door can be a great way to allow your pets to come and go as they please, but sometimes leads to unwanted visitors too. Petvation is looking to change that with the help of AI facial recognition and a mobile app.
You may already have a little entry in your door that only gives access to your cats or dogs, but that likely means your pets will have to wear some sort of “key” on a collar to identify them and unlock the pet door. And these can be somewhat heavy. Therefore, considerate Petvation developers have developed a smart pet door without a “key”. They make use of the face recognition technology that has already been applied to our smartphones and computers to ensure that access to the home is only given to authorized(批准) family members.
However, the developers recognize that identifying and authorizing animal faces is more challenging than with humans, and therefore employ multiple-image full-body animal recognition. The AI model is expected to be continuously improved over time for better accuracy. And in addition to identifying cats and dogs, the system can also recognize all kinds of animals, so the entry point will remain firmly closed to unwanted guests.
The company says that three independent safety mechanisms(机制) are employed to “keep your pet safe from head to tail.” First, sensors detect and monitor the cats or dogs as they approach and pass through. There’s also a light anti-pinch(防夹) mechanism in place to ensure that tails aren’t caught in a descending door. And finally the system checks all sensors during operation and will enter a safe mode if issues are detected, and inform the human in charge through a mobile app that the Petvation needs some attention.
That app is also used for setup and control, including the ability to give access to specific household pets and keep track of the comings and goings of pets. The door can also be opened or closed remotely from within the app.
The Petvation team is currently raising production funds on Kickstarter, where pledges(抵押) start at US$169. If all goes to plan, shipping is estimated to start in October.

1.What does the underlined word “that” refer to?
A Wrong pets’ entry.
B The mobile app.
C AI facial recognition.
D Installing another door.
解析：选A。A词意指代题。根据划线单词前面的“sometimes leads to unwanted visitors too”可知，有的宠物主人会在家的大门上安装一个小门让宠物通过，但是这种小门有一个缺点，那就是很多其他的动物也能从小门进到家中。为了解决这个问题，Petvation研发了一款加了面部识别功能的智能宠物门。故选A。
2.What can be inferred from Paragraphs 2 and 3?
A Traditional pet doors are difficult to unlock.
B The smart pet door uses completely new technology.
C The smart pet door system can only identify cats and dogs.
D Developers improved face recognition technology in the door.
解析：选D。D细节理解题。根据第三段第一句可知，识别和授权动物面部比识别人类面部更具挑战性，因此开发人员采用了多图像全身动物识别技术，即他们改进了面部识别技术。故选D。
3.In which situation does the system “contact” the pet owner through a mobile app?
A There is something wrong with the sensors.
B Pets’ tails aren’t caught in a descending door.
C The phone battery is going to be dead.
D Unwanted visitors want to enter the door.
解析：选A。A细节理解题。根据第五段最后一句的“And finally the system checks all sensors during operation and will enter a safe mode if issues are detected, and inform the human in charge through a mobile app that the Petvation needs some attention.”可知，每次门打开并关闭时，设备都会交叉检查所有板载传感器的状态，以确保它们状态一致。如果有异常，用户将收到有关情况的通知，门将进入安全模式。故选A。
4.What type of writing is this text?
A A report.
B An announcement.
C An advertisement.
D A poster.
解析：选C。C推理判断题。本文主要介绍了一款智能宠物门，包括它的工作原理和操作方式，并在最后一段告知了预计发货时间，由此可推断本文是关于这款智能宠物门的一篇广告。故选C。
